TY - JOUR A1 - Zhou, Wei A1 - Kliegl, Reinhold A1 - Yan, Ming T1 - A validation of parafoveal semantic information extraction in reading Chinese JF - Journal of research in reading : a journal of the United Kingdom Reading Association N2 - Parafoveal semantic processing has recently been well documented in reading Chinese sentences, presumably because of language-specific features. However, because of a large variation of fixation landing positions on pretarget words, some preview words actually were located in foveal vision when readers' eyes landed close to the end of the pretarget words. None of the previous studies has completely ruled out a possibility that the semantic preview effects might mainly arise from these foveally processed preview words. This case, whether previously observed positive evidence for parafoveal semantic processing can still hold, has been called into question. Using linear mixed models, we demonstrate in this study that semantic preview benefit from word N+1 decreased if fixation on pretarget word N was close to the preview. We argue that parafoveal semantic processing is not a consequence of foveally processed preview words.

This suggests that dyslexics encounter local processing difficulties, which presumably induce a narrower perceptual span. Consequently, dyslexics should suffer less than normal readers from removing parafoveal preview. Here we used a gaze-contingent moving window paradigm in a RAN task to experimentally test this prediction. Results indicate that dyslexics extract less parafoveal information than control children. We propose that more attentional resources are recruited to the foveal processing because of dyslexics' less automatized translation of visual symbols into phonological output, thereby causing a reduction of the perceptual span. This in turn leads to less efficient preactivation of parafoveal information and, hence, more difficulty in processing the next foveal item.

Such differences in fixation probability may imply a selection effect for multivariate analyses of eye-movement corpora if selection effects correlate with word properties of skipped words. For example, with fewer fixations on short and highly frequent words the power to detect parafoveal-on-foveal effects is reduced. We demonstrate that increasing the fixation probability on function words with a manipulation of the expected difficulty and frequency of questions reduces an age difference in skipping probability (i.e., old adults become comparable to young adults) and helps to uncover significant parafoveal-on-foveal effects in this group of old adults. We discuss implications for the comparison of results of eye-movement research based on multivariate analysis of corpus data with those from display-contingent manipulations of target words.

Based on Ackerman's (1996) notion of trait complexes, specific interest profiles of gifted high-school graduates can be expected. Aims.Vocational interests of gifted and highly achieving adolescents were compared to those of their less intelligent/achieving peers according to Holland's (1997) RIASEC model. Further, the impact of intelligence and achievement on interests were analysed while statistically controlling for potentially influencing variables. Changes in interests over time were investigated. Sample.N= 4,694 German students (age: M= 19.5, SD= .80; 54.6% females) participated in the study (TOSCA; Koller, Watermann, Trautwein, & Ludtke, 2004). Method. Interests were assessed in participants' final year at school and again 2 years later (N= 2,318). Results.Gifted participants reported stronger investigative and realistic interests, but lower social interests than less intelligent participants. Highly achieving participants reported higher investigative and (in wave 2) higher artistic interests. Considerable gender differences were found: gifted girls had a flat interest profile, while gifted boys had pronounced realistic and investigative and low social interests. Multilevel multiple regression analyses predicting interests by intelligence and school achievement revealed stable interest profiles. Beyond a strong gender effect, intelligence and school achievement each contributed substantially to the prediction of vocational interests. Conclusions.At the time around graduation from high school, gifted young adults show stable interest profiles, which strongly differ between gender and intelligence groups. These differences are relevant for programmes for the gifted and for vocational counselling.

In a high-powered study (N = 14,348), we replicated previous research showing that women report higher levels of Agreeableness, Conscientiousness, Extraversion and Neuroticism. For implicit measures, gender differences were much smaller for all, and opposite in sign for Extraversion. Somewhat higher levels of implicit Neuroticism and Agreeableness were observed in women, and somewhat higher levels of implicit Extraversion and Openness were observed in men. There was no gender difference in implicit Conscientiousness. A possible explanation is that explicit self-concepts partly reflect social norms and self-expectations about gender roles, while implicit self-concepts may mostly reflect self-related experiences.

Here, we contribute to this issue by contrasting regular (regular stem, regular suffix) with semi-irregular (regular stem, irregular suffix) and irregular (irregular stem, irregular suffix) participle formation in a visual priming experiment on German verb inflection. We measured ERPs and RTs and manipulated the inflectional and meaning relatedness between primes and targets. Inflected verb targets (e. g., leite, "head") were preceded either by themselves, by their participle (geleitet, "headed"), by a semantically related verb in the same inflection as the target (fuhre, "guide") or in the participle form (gefuhrt, "guided"), or by an unrelated verb in the same inflection (nenne, "name"). Results showed that behavioral and ERP priming effects were gradually affected by verb regularity. Regular participles produced a widely distributed frontal and parietal effect, irregular participles produced a small left parietal effect, and semi-irregular participles yielded an effect in-between these two in terms of amplitude and topography. The behavioral and ERP effects further showed that the priming because of participles differs from that because of semantic associates for all verb types. These findings argue for a single processing system that generates participle priming effects for regular, semi-irregular, and irregular verb inflection. Together, the findings provide evidence that the linguistic categories of verb inflection are processed continuously. We present a single-system model that can adequately account for such graded effects.

T1 - Your neighbors define your value a study of spatial bias in number comparison JF - Acta psychologica : international journal of psychonomics N2 - Several chronometric biases in numerical cognition have informed our understanding of a mental number line (MNL). Complementing this approach, we investigated spatial performance in a magnitude comparison task. Participants located the larger or smaller number of a pair on a horizontal line representing the interval from 0 to 10. Experiments 1 and 2 used only number pairs one unit apart and found that digits were localized farther to the right with "select larger" instructions than with "select smaller" instructions. However, when numerical distance was varied (Experiment 3), digits were localized away from numerically near neighbors. This repulsion effect reveals context-specific distortions in number representation not previously noticed with chronometric measures.

T1 - Free associations as a measure of stable implicit attitudes JF - European journal of personality N2 - Two studies explored the psychometric properties of free association methods for the assessment of attitudes. Even though the stability of the actual associations was rather low, psychometric properties of the valence estimates of the free associations were highly satisfactory. Valence estimates of associations were provided by independent judges who rated the valence of the associations that were generated by participants. Valence estimates of the associations showed satisfactory internal consistencies and retest reliabilities over three weeks. Additionally, valence estimates of the associations were significantly and independently related to both explicit self-reported attitudes and implicit attitudes that were assessed with an OssiWessi Implicit Association Test. Free association methods represent a useful complement to the family of implicit measures and are especially suitable for the assessment of non-relative attitudes towards single attitude objects.

The present prospective study investigates, in humans, the long-term impact of maternal responsiveness and stimulation during early mother-child interaction on adrenocorticotropic hormone (ACTH) and cortisol response to a psychosocial laboratory stressor in adulthood. The data are from an epidemiological cohort study of the long-term outcome of early risk factors assessed at birth. At age 3 months, mothers and infants were videotaped during a 10-min standardized nursing and playing situation and evaluated by trained raters for maternal stimulation and infant and maternal responsiveness. At age 19 years, 270 participants (146 females, 124 males) completed the Trier Social Stress Test. The results indicated that less maternal stimulation during early interaction at age 3 months predicted diminished plasma ACTH and cortisol increase in response to acute psychosocial stress in male, but not female offspring. In contrast, maternal responsiveness was found to be unrelated to hypothalamic-pituitary-adrenal (HPA) reactivity. In accordance with the findings from animal research, the present study provides prospective evidence in humans of a long-term association between early maternal interaction behavior and the offspring's hormonal stress response in young adulthood, suggesting that poor maternal stimulation in early infancy may result in reduced HPA axis reactivity to an acute psychosocial stressor in males.

In order to clarify this question, we conducted interviews with 26 elementary school students and applied content analysis to examine the interview protocols. Although the results support some of the theoretically postulated components, they suggest that questionnaire measures have neglected some important aspects of reading motivation (e. g., reading to regulate one's feelings, reading to relax). Finally, consequences for the revision of reading motivation questionnaires were discussed.

A positive association between intrinsic reading motivation and reading amount was assumed, whereas a negative contribution to reading amount was expected for extrinsic reading motivation. As control variables, lower order reading comprehension (comprised of word- and sentence-level comprehension), gender, and social desirability were taken into account. Structural equation analyses indicated that reading amount fully mediated the positive effect of intrinsic reading motivation on higher order comprehension, whereas extrinsic reading motivation exerted both indirect and direct negative effects on comprehension. Additional analyses confirmed a suppression effect and showed significant negative contributions of extrinsic reading motivation to reading amount and reading comprehension only when intrinsic reading motivation was simultaneously included as a predictor.

Metacognitive strategy knowledge and test anxiety were expected to be equally associated with comprehension in the two test conditions. Participants were 424 eighth- and ninth-grade students. They were presented with several instruments measuring cognitive and motivational predictors and read a text on a mathematical topic; then half of them took a test on comprehension either without or with text access. Based on multiple-group structural equation modeling, results indicated that reasoning ability, decoding ability, and metacognitive strategy knowledge significantly predicted comprehension only in the without-text condition, whereas achievement motivation and test anxiety significantly predicted comprehension only in the with-text condition.

However, to date there are few neuropsychological studies on cognitive flexibility among adolescent patients with AD, especially on gender differences in AD. Here, we investigate cognitive functions, especially cognitive flexibility, in adolescent patients with unipolar AD (UAD) compared to a healthy control group (CG). Method: The study population consists of 17 male patients (M-age = 15.4 +/- 1.3) and 22 female patients with UAD (M-age = 15.6 +/- 1.4) as well as 20 male (M-age = 16.0 +/- 1.0) and 30 female (M-age = 15.7 +/- 0.9) healthy adolescents. A neuropsychological test battery was conducted, and depressive symptoms, psychological stress, and intelligence were also assessed. Results: The analyses revealed no significant group differences regarding cognitive flexibility or visual processing speed, albeit slight better performance in motor processing speed for the CG. Furthermore, no gender differences were observed regarding cognitive flexibility, though female subjects general displayed better performance in processing speed. Conclusions: Overall, there are no indications for serious deficits and specific gender differences in cognitive flexibility or processing speed in adolescent patients with UAD. Independent of psychological distress, female subjects seem to have some advantages in processing speed.

In speech, rhythm groups auditory events, e.g., sounds and pauses, together into words, making their boundaries acoustically prominent and aiding word segmentation and recognition by the hearer. After word recognition, the hearer is able to retrieve word meaning form his mental lexicon, integrating it with information from other linguistic domains, such as semantics, syntax and pragmatics, until comprehension is achieved. The importance of speech rhythm, however, is not restricted to word segmentation and recognition only. Beyond the word level rhythm continues to operate as an organization device, interacting with different linguistic domains, such as syntax and semantics, and grouping words into larger prosodic constituents, organized in a prosodic hierarchy. This dissertation investigates the function of speech rhythm as a sentence segmentation device during syntactic ambiguity processing, possible limitations on its use, i.e., in the context of second language processing, and its transferability as cognitive skill to the music domain. N2 - Rhythmus ist eine zeitliche und systematische Organisierung von akustischen Ereignissen im Sinne von Prominenz, Timing und Gruppierung. In der Sprache gruppiert Rhythmus auditorische Ereignisse, wie zum Beispiel Laute und Pausen, zu Wörtern und kreiert dadurch akustisch prominente Wortgrenzen die dem Hörer bei der Segmentierung und Erkennung von Wörtern helfen können. Werden Wörter erkannt, kann der Hörer die Wörterbedeutung aus seinem Lexicon abrufen und sie mit der Information aus verschiedenen linguistischen Bereichen, semantischer, syntaktischer und pragmatischer Bereich, integrieren. Die Rolle von Sprachrhythmus ist jedoch nicht auf Wortsegmentierung und Erkennung begrenzt. Er spielt eine entscheidender Rolle in der Bildung von der Prosodischer Hierarchie, die die linguistischen Konstituenten organisiert. Die vorliegende Dissertation untersucht die Rolle des Sprachrhythmus in a) der Segmentierung von Sätzen, basierend auf der Verarbeitung von syntaktischen Ambiguitäten, b) mögliche Grenzen dieser Segmentierungsfunktion im Bereich der Zweitsprachverarbeitung, und c) mögliche Gemeinsamkeiten zwischen der kognitiven Fähigkeit Rhythmus in Sprache und Musik zu erkennen und zur Segmentierung zu nutzen.

We see a tennis racket hitting a ball and sense that it caused the ball to fly over the net; we may also have an eerie but equally compelling experience of causality if the streetlights turn on just as we slam our car's door. Both perceptual [1] and cognitive [2] processes have been proposed to explain these spontaneous inferences, but without decisive evidence one way or the other, the question remains wide open [3-8]. Here, we address this long-standing debate using visual adaptation-a powerful tool to uncover neural populations that specialize in the analysis of specific visual features [9-12]. After prolonged viewing of causal collision events called "launches" [1], subsequently viewed events were judged more often as noncausal. These negative aftereffects of exposure to collisions are spatially localized in retinotopic coordinates, the reference frame shared by the retina and visual cortex. They are not explained by adaptation to other stimulus features and reveal visual routines in retinotopic cortex that detect and adapt to cause and effect in simple collision stimuli.

Working memory has been regarded as the process responsible for those cognitive activities. This thesis addresses the question: what limits working-memory capacity (WMC)? A question that still remains controversial (Barrouillet & Camos, 2009; Lewandowsky, Oberauer, & Brown, 2009). This study attempted to answer this question by proposing that the dynamics between the causes of forgetting and the processes helping the maintenance, and the manipulation of the memoranda are the key aspects in understanding the limits of WMC. Chapter 1 introduced key constructs and the strategy to examine the dynamics between inhibition, attentional control, and the causes of forgetting in working memory. The study in Chapter 2 tested the performance of children, young adults, and old adults in a working-memory updating-task with two conditions: one condition included go steps and the other condition included go, and no-go steps. The interference model (IM; Oberauer & Kliegl, 2006), a model proposing interference-related mechanisms as the main cause of forgetting was used to simultaneously fit the data of these age groups. In addition to the interference-related parameters reflecting interference by feature overwriting and interference by confusion, and in addition to the parameters reflecting the speed of processing, the study included a new parameter that captured the time for switching between go steps and no-go steps. The study indicated that children and young adults were less susceptible than old adults to interference by feature overwriting; children were the most susceptible to interference by confusion, followed by old adults and then by young adults; young adults presented the higher rate of processing, followed by children and then by old adults; and young adults were the fastest group switching from go steps to no-go steps. Chapter 3 examined the dynamics between causes of forgetting and the inhibition of a prepotent response in the context of three formal models of the limits of WMC: A resources model, a decay-based model, and three versions of the IM. The resources model was built on the assumption that a limited and shared source of activation for the maintenance and manipulation of the objects underlies the limits of WMC. The decay model assumes that memory traces of the working-memory objects decay over time if they are not reactivated via different mechanisms of maintenance. The IM, already described, proposes that interference-related mechanisms explain the limits of WMC. In two experiments and in a reanalysis of data of the second experiment, one version of the IM received more statistical support from the data. This version of the IM proposes that interference by feature overwriting and interference by confusion are the main factors underlying the limits of WMC. In addition, the model suggests that experimental conditions involving the inhibition of a prepotent response reduce the speed of processing and promotes the involuntary activation of irrelevant information in working memory. Chapter 4 summed up Chapter 2 and 3 and discussed their findings and presented how this thesis has provided evidence of interference-related mechanisms as the main cause of forgetting, and it has attempted to clarify the role of inhibition and attentional control in working memory. With the implementation of formal models and experimental manipulations in the framework of nonlinear mixed models the data offered explanations of causes of forgetting and the role of inhibition in WMC at different levels: developmental effects, aging effects, effects related to experimental manipulations and individual differences in these effects. Thus, the present approach afforded a comprehensive view of a large number of factors limiting WMC. N2 - Bei vielen kognitiven Aktivitäten ist die vorübergehende Speicherung und Manipulation von Mental Objects ein notwendiger Schritt um ein kognitiven Ziel zu erreichen. Diese Prozesse finden im Arbeitsgedächtnis statt. Diese Dissertation behandelt die Frage wodurch die Kapazität des Arbeitsgedächtnisses (Working Memory Capacity, WMC) limitiert wird. Dieses Thema wurde in der Literatur bislang kontrovers diskutiert (Barrouillet & Camos, 2009; Lewandowsky, Oberauer, & Brown, 2009). Es wird hier vorgeschlagen, dass die Dynamik zwischen den Ursachen des Vergessens und den Prozessen, welche die Aufrechterhaltung unterstützen, und die Manipulation der Memoranda die Grundlagen für das Verständnis der WMC-Limitierung bildet. Kapitel 1 führt in das Thema ein und erklärt die Strategie um die Dynamik zwischen Hemmung, Aufmerksamkeitskontrolle und den Ursachen des Vergessens im Arbeitsgedächtnis zu untersuchen. Die Untersuchung in Kapitel 2 testet die Leistung von Kindern, jungen und alten Erwachsenen in einem Working Memory Updating Task mit zwei Bedingungen; eine beinhaltet Go-Steps, die andere Go- und No-Go Steps. Die Daten der Experimentalgruppen wurden mithilfe des Interferenzmodells (IM; Oberauer & Kliegl, 2006), welches Interferenz-ähnliche Mechanismen als Hauptursache des Vergessens postuliert, simultan gefitted. Zusätzlich zu Interferenz-ähnlichen Parametern, die Interferenz durch Feature-Overwriting oder Ablenkung beinhalten, sowie Parametern welche die Geschwindigkeit der Informationsverarbeitung repräsentieren, wurde ein neuer Parameter eingeführt. Dieser beschreibt die benötigte Zeit um zwischen Go- und No-Go Steps zu unterscheiden. Es wird gezeigt, dass Kinder und junge Erwachsene weniger anfällig für Interferenz durch Feature-Overwriting waren als alte Erwachsene. Kinder waren am anfälligsten für Interferenz durch Ablenkung, gefolgt von alten Erwachsenen und jungen Erwachsenen. Junge Erwachsene zeigten die schnellste Verarbeitungsrate, gefolgt von Kindern und alten Erwachsenen. Weiterhin wechselten junge Erwachsene am schnellsten zwischen Go- und No-Go Steps. In Kapitel 3 werden die Dynamik zwischen den Ursachen des Vergessens und der Hemmung einer Prepotent Response im Kontext von folgenden drei formellen Modellen der Beschränkung des WMC beschrieben: Ein Ressource-Modell, ein Decay-Based-Modell und drei Versionen des IMs. Die Annahme, dass der Begrenzung der WMC eine beschränkte und eine gemeinsame Ursache der Aktivierung für die Aufrechterhaltung und Manipulation von Objekten zugrunde liegt wurde benutzt um das Ressource-Modell zu konstruieren. Das Decay-Modell nimmt an, dass Memory-Traces von Objekten im Arbeitsgedächtnis mit der Zeit verblassen, wenn sie nicht durch Mechanismen zur Aufrechterhaltung reaktiviert werden. Das IM (s.o.) besagt, dass Interferenz-ähnliche Mechanismen die Limitierung des WMC erklären können. In zwei Experimenten sowie einer Reanalyse der Daten des zweiten Experiments konnte eine der Versionen des IM als statistisch plausibler als die anderen beiden erkannt werden. In dieser Version des IM werden Feature-Overwriting und Interferenz durch Ablenkung als Hauptfaktoren für die Limitierung des WMCs beschrieben. Zusätzlich werden experimentelle Bedingungen welche eine Hemmung der Prepotent Response beinhalten als reduzierende Faktoren für die Geschwindigkeit der Informationsverarbeitung sowie für die unfreiwillige Aktivierung irrelevanter Information im WM genannt. Kapitel 4 fasst Kapitel 2 und 3 zusammen und zeigt, wie diese Arbeit Evidenz für Interferenz-ähnliche Mechanismen als Hauptursache des Vergessens liefert; weiterhin wird versucht die Rolle der Hemmung und Aufmerksamkeitskontrolle im Arbeitsgedächtnis zu erklären. Mit der Implementierung von formalen Modellen und experimentellen Manipulationen im Rahmen von Nonlinear-Mixed-Models konnten die Ursachen des Vergessens und die Rolle der Hemmung im WMC auf verschiedenen Ebenen erklärt werden. Entwicklungseffekte, altersbedingte Effekte, Effekte durch experimentelle Manipulationen sowie individuelle Unterschiede in diesen Effekten spielten eine wichtige Rolle. Die hier vorgestellte Herangehensweise ermöglicht daher einen umfassenden Blick auf eine große Anzahl auf WMC-limitierende Faktoren.

The task consisted of mentally shifting spatial positions within a grid according to arrows, their color signaling either only go (control) or go/no-go conditions. The interference model (IM) of Oberauer and Kliegl (2006) was simultaneously fitted to the data of all groups. In addition to the 3 main model parameters (feature overlap, noise, and processing rate), we estimated the time for switching between go and no-go steps as a new model parameter. In this study, we examined the IM parameters across the life span. The IM parameter estimates show that (a) conditions were not different in interference by feature overlap and interference by confusion; (b) switching costs time; (c) young adults and children were less susceptible than old adults to interference due to feature overlap; (d) noise was highest for children, followed by old and young adults; (e) old adults differed from children and young adults in lower processing rate; and (f) children and old adults had a larger switch cost between go steps and no-go steps. Thus, the results of this study indicated that across age, the IM parameters contribute distinctively for explaining the limits of WMC.

Second, we examined whether preschoolers' selective imitation is influenced by differences in the modeled actions and/or by the situational context. Finally, we investigated how verbal cues given by the model affect preschoolers' imitation. Participants (3- to 5-year-olds) watched an adult performing an unusual action in three imitation tasks (touch light, house, and obstacle). In two conditions, the model either was or was not restricted by situational constraints. In addition, the model verbalized either the goal that was to be achieved, the movement, or none of the action components. Preschoolers always acted on the objects without constraints. Results revealed differences in preschoolers' selective imitation across the tasks. In the house task, they showed the selective imitation pattern that has been interpreted as rational, imitating the unusual action more often in the no-constraint condition than in the constraint condition. In contrast, in the touch light task, preschoolers imitated the unusual head touch irrespective of the model's constraints or of the verbal cues that had been presented. Finally, in the obstacle task, children mostly emulated the observed goal irrespective of the presence of the constraint, but they increased their imitation of the unusual action when the movement had been emphasized. Overall, our data suggest that preschoolers adjust their imitative behavior to context-specific information about objects, actions, and their interpretations of the model's intention to teach something.

N2 - We measured Chinese dyslexic and control children's eye movements during rapid automatized naming (RAN) with alphanumeric (digits) and symbolic (dice surfaces) stimuli. Both types of stimuli required identical oral responses, controlling for effects associated with speech production. Results showed that naming dice was much slower than naming digits for both groups, but group differences in eye-movement measures and in the eye-voice span (i.e. the distance between the currently fixated item and the voiced item) were generally larger in digit-RAN than in dice-RAN. In addition, dyslexics were less efficient in parafoveal processing in these RAN tasks. Since the two RAN tasks required the same phonological output and on the assumption that naming dice is less practiced than naming digits in general, the results suggest that the translation of alphanumeric visual symbols into phonological codes is less efficient in dyslexic children. The dissociation of the print-to-sound conversion and phonological representation suggests that the degree of automaticity in translation from visual symbols to phonological codes in addition to phonological processing per se is also critical to understanding dyslexia.

A1 - Kliegl, Reinhold T1 - The generation of secondary saccades without postsaccadic visual feedback JF - Journal of vision N2 - Primary saccades are often followed by small secondary saccades, which are generally thought to reduce the distance between the saccade endpoint and target location. Accumulated evidence demonstrates that secondary saccades are subject to various influences, among which retinal feedback during postsaccadic fixation constitutes only one important signal. Recently, we reported that target eccentricity and an orientation bias influence the generation of secondary saccades. In the present study, we examine secondary saccades in the absence of postsaccadic visual feedback. Although extraretinal signals (e.g., efference copy) have received widespread attention in eye-movement studies, it is still unclear whether an extraretinal error signal contributes to the programming of secondary saccades. We have observed that secondary saccade latency and amplitude depend on primary saccade error despite the absence of postsaccadic visual feedback. Strong evidence for an extraretinal error signal influencing secondary saccade programming is given by the observation that secondary saccades are more likely to be oriented in a direction opposite to the primary saccade as primary saccade error shifts from target undershoot to overshoot. We further show how the functional relationship between primary saccade landing position and secondary saccade characteristics varies as a function of target eccentricity. We propose that initial target eccentricity and an extraretinal error signal codetermine the postsaccadic activity distribution in the saccadic motor map when no visual feedback is available.

CY - London ER - TY - THES A1 - Ohl, Sven T1 - Small eye movements during fixation : the case of postsaccadic fixation and preparatory influences T1 - Kleine Augenbewegungen während der Fixation: Der Fall der postsakkadischen Fixation und vorbereitender Einflüsse N2 - Describing human eye movement behavior as an alternating sequence of saccades and fixations turns out to be an oversimplification because the eyes continue to move during fixation. Small-amplitude saccades (e.g., microsaccades) are typically observed 1-2 times per second during fixation. Research on microsaccades came in two waves. Early studies on microsaccades were dominated by the question whether microsaccades affect visual perception, and by studies on the role of microsaccades in the process of fixation control. The lack of evidence for a unique role of microsaccades led to a very critical view on the importance of microsaccades. Over the last years, microsaccades moved into focus again, revealing many interactions with perception, oculomotor control and cognition, as well as intriguing new insights into the neurophysiological implementation of microsaccades. In contrast to early studies on microsaccades, recent findings on microsaccades were accompanied by the development of models of microsaccade generation. While the exact generating mechanisms vary between the models, they still share the assumption that microsaccades are generated in a topographically organized saccade motor map that includes a representation for small-amplitude saccades in the center of the map (with its neurophysiological implementation in the rostral pole of the superior colliculus). In the present thesis I criticize that models of microsaccade generation are exclusively based on results obtained during prolonged presaccadic fixation. I argue that microsaccades should also be studied in a more natural situation, namely the fixation following large saccadic eye movements. Studying postsaccadic fixation offers a new window to falsify models that aim to account for the generation of small eye movements. I demonstrate that error signals (visual and extra-retinal), as well as non-error signals like target eccentricity influence the characteristics of small-amplitude eye movements. These findings require a modification of a model introduced by Rolfs, Kliegl and Engbert (2008) in order to account for the generation of small-amplitude saccades during postsaccadic fixation. Moreover, I present a promising type of survival analysis that allowed me to examine time-dependent influences on postsaccadic eye movements. In addition, I examined the interplay of postsaccadic eye movements and postsaccadic location judgments, highlighting the need to include postsaccadic eye movements as covariate in the analyses of location judgments in the presented paradigm. In a second goal, I tested model predictions concerning preparatory influences on microsaccade generation during presaccadic fixation. The observation, that the preparatory set significantly influenced microsaccade rate, supports the critical model assumption that increased fixation-related activity results in a larger number of microsaccades. In the present thesis I present important influences on the generation of small-amplitude saccades during fixation. These eye movements constitute a rich oculomotor behavior which still poses many research questions. Certainly, small-amplitude saccades represent an interesting source of information and will continue to influence future studies on perception and cognition. N2 - Die Beschreibung des Blickbewegungsverhaltens als eine sich abwechselnde Folge von Sakkaden und Fixationen stellt eine starke Vereinfachung dar, denn auch während einer Fixation bewegen sich die Augen. Typischerweise treten Bewegungen von kleiner Amplitude (z.B. Mikrosakkaden), 1-2 mal pro Sekunde während einer Fixation auf. Frühe Studien zu Mikrosakkaden wurden von Fragen bezüglich des Einflusses von Mikrosakkaden auf die visuelle Wahrnehmung, und Studien zu der Rolle von Mikrosakkaden bei der Fixationskontrolle dominiert. Fehlende Evidenz für eine Rolle, die ausschließlich Mikrosakkaden zufällt, führten zu einer sehr kritischen Betrachtung von Mikrosakkaden. In den letzten Jahren rückten Mikrosakkaden wieder mehr in den Fokus. Vielerlei Zusammenhänge mit Wahrnehmung, okulomotorischer Kontrolle und Kognition, sowie neue Erkenntnisse bezüglich der neurophysiologischen Implementierung von Mikrosakkaden konnten aufgedeckt werden. In den letzten Jahren wurden verschiedene Modelle der Mikrosakkadengenerierung vorgestellt. Auch wenn sich diese in ihren exakten Mechanismen unterscheiden, so teilen sie doch die Annahme, dass Mikrosakkaden in einer topographisch organisierten motorischen Karte für Sakkaden ausgelöst werden. Diese Karten beinhalten eine Repräsentation für klein-amplitudige Sakkaden im Zentrum der Karte (mit dem rostralen Pol der colliculi superiores als neurophysiologische Implementierung). In der vorliegenden Arbeit kritisiere ich, dass Modelle der Mikrosakkadengenerierung ausschließlich auf Resultaten langanhaltender präsakkadischer Fixation beruhen. Ich führe an, dass Mikrosakkaden in einer natürlicheren Situation untersucht werden sollten, nämlich während der Fixation nach einer großen Sakkade. Die Untersuchung postsakkadischer Fixation bietet eine neue Möglichkeit Modelle der Mikrosakkadengenerierung zu falsifizieren. In den Studien zeige ich, dass Signale über den Fehler in der Sakkadenlandeposition (visuelle und extra-retinale), sowie fehler-unabhängige Signale, wie die Zielreiz-Exzentrizität, einen entscheidenden Einfluss auf kleine Sakkaden haben. Diese Resultate erfordern Modifikationen an dem kürzlich eingeführten Modell von Rolfs, Kliegl und Engbert (2008), um die Generierung von kleinen Sakkaden auch während der postsakkadischen Fixation erklären zu können. Darüber hinaus präsentiere ich eine viel versprechende Ereigniszeitanalyse, die uns erlaubt zeitabhängige Einflüsse auf das postsakkadische Blickbewegungsverhalten zu untersuchen. Außerdem untersuche ich das Zusammenspiel von postsakkadischen Augenbewegungen und postsakkadischen Positionsurteilen. Dabei wird die Bedeutung von postsakkadischen Augenbewegungen als Kovariate in den statistischen Analysen betont. Ein zweites Ziel dieser Arbeit besteht darin Modellvorhersagen bezüglich vorbereitender Einflüsse auf die Mikrosakkadengenerierung zu untersuchen. Die Ergebnisse, hinsichtlich eines signifikanten Einflusses des preparatory set auf die Mikrosakkadenrate unterstützt die wesentliche Modellannahme, dass erhöhte fixationsbezogene Aktivität zu einer größeren Anzahl an Mikrosakkaden führt. In der vorliegenden Arbeit präsentiere ich wichtige Einflüsse auf die Generierung von kleinen Sakkaden während der Fixation. Diese Augenbewegungen stellen ein vielseitiges okulomorisches Verhalten dar, welche weiterhin zahlreiche Fragen mit sich bringen und sicherlich zukünftige Studien zu Wahrnehmung und Kognition beeinflussen werden.

Für diesen Übersetzungsprozess ist es zielführend, ästhetische Kundenbedürfnisse zu kennen, denn die Qualität einer Designlösung hängt auch davon ab, inwieweit der Designer Kundenbe-dürfnisse und damit das Designproblem richtig erfasst hat (Ulrich, 2006). Eine Grundlage hierfür entsteht durch eine erfolgreiche Designer-Nutzer-Interaktion und den Aufbau eines gemeinsamen Kontextwissens (Lee, Popovich, Blackler & Lee, 2009). Zwischen Designern und Kunden findet jedoch häufig kein direkter Austausch statt (Zeisel, 2006). Zudem belegen Befunde der Kunst- und Produktästhetikforschung, dass der Erwerb von gestalterischem Wissen und damit die Entwicklung ästhetischer Expertise mit Veränderungen der kognitiven Verarbeitung ästhetischer Objekte einhergeht, die sich in Wahrnehmung, Bewertung und Verhalten manifestieren. Damit ist auch zu erwarten, dass die Präferenzurteile von Designern und Kunden bei der ästhetischen Bewertung von Design nicht immer konvergieren. Ziel der vorliegenden Arbeit war daher die systematische Untersuchung dieser expertisebedingten Wahrnehmungs- und Bewertungsunterschiede zwischen designge-schulten und ungeschulten Personen bei der Betrachtung von Automobildesign. Damit sollten Perzeption, Verarbeitung und Bewertung von Automobildesign durch design-ungeschulte Personen transparenter gemacht und mit der Verarbeitung designgeschul-ter Personen verglichen werden, um einen Beitrag zur gemeinsamen Wissensbasis und damit einer erfolgreichen Designer-Nutzer-Interaktion zu leisten. Die theoretische Einbettung der Arbeit basierte auf dem Modell ästhetischer Erfahrung und ästheti-schen Urteilens von Leder, Belke, Oeberst und Augustin (2004), welches konkrete Annahmen zu Verarbeitungsunterschieden von ästhetischen Objekten zwischen Experten und Laien bietet, die bisher allerdings noch nicht umfassend geprüft wurden. Den ersten Schwerpunkt dieser Arbeit bildete die Untersuchung von Unter-schieden zwischen Designern und designungeschulten Rezipienten bei der Beschrei-bung und Bewertung auf dem Markt vorhandenen Fahrzeugdesigns. Dabei sollte auch geprüft werden, ob eine lexikalische Verbindung zwischen Beschreibungsattributen von Fahrzeugrezipienten und den postulierten Markenwerten von Automobilmarken hergestellt werden kann. Diesem ersten Untersuchungsanliegen wurde in zwei Studien nachgegangen: Studie I diente der Erhebung von Beschreibungsattributen mittels Triadenvergleich in Anlehnung an Kelly (1955). Es wurde geprüft, ob designgeschulte Teilnehmer produkti-ver verbalisieren, dabei anteilig mehr symbolbezogene als formbezogene Attribute generieren und innerhalb ihrer Gruppe häufiger gleiche Attribute nutzen als designun-geschulte Teilnehmer. Hierfür beschrieben 20 designgeschulte Probanden und 20 designungeschulte Probanden mit selbst gewählten Adjektiven die Unterschiede zwischen vier präsentierten Fahrzeugen. Die Gruppen nutzten dabei entgegen der Annahmen sehr ähnliche Attribute und unterschieden sich somit auch nicht in ihrer Verwendung symbolbezogener und formbezogener Attribute. Die generierten Attribute wurden mittels Prototypenansatz (Amelang & Zielinski, 2002) den ermittelten und nachfolgend kategorisierten Markenwerten von 10 Automobilherstellern zugeordnet, so dass sechs Skalen zur Erfassung der ästhetischen Wirkung von Fahrzeugen entstanden. In Studie II wurde ein diese sechs Skalen umfassender Fragebogen an einer Stichprobe von 83 Designern und Designstudierenden sowie 98 Probanden ohne Designausbildung in einer Onlinebefragung hinsichtlich Skalenkonsistenz geprüft. Außerdem wurden erste Annahmen aus dem Modell von Leder et al. (2004) abgeleitet und durch einen Vergleich der beiden Teilnehmergruppen hinsichtlich der Bewertung der vier präsentierten Fahrzeugmodelle für die Skalen mit guter interner Konsistenz (Attraktivität, Dynamik, Fortschritt, Qualität), sowie eines ästhetischen Gesamturteils, der benötigten Bewertungszeit und der Automobilaffinität überprüft. Hierbei vergaben Designstudierende und insbesondere ausgebildete Designer radikalere Bewertungen als Designlaien, benötigten mehr Zeit bei der Bewertung und waren automobilaffiner als die ungeschulten Befragungsteilnehmer. Den zweiten Schwerpunkt der Arbeit bildete eine konzeptionelle Zusammen-führung der Annahmen des Modells von Leder et al. (2004) und der Postulate zur Wirkung von Objekteigenschaften auf ästhetische Urteile (Berlyne, 1971; Martindale, 1988; Silvia, 2005b). Konkret sollte geprüft werden, welchen Einfluss marktrelevante Objekteigenschaften, wie z.B. das Ausmaß an Innovativität, auf die durch Expertise moderierte Bewertung von Design haben. In den Studien III und IV wurden hierfür systematisch bezüglich Innovativität und Balance gestufte Linienmodelle von Fahrzeu-gen präsentiert. In Studie III wurden die Modelle in einer Onlinebefragung durch 18 Designstudierende und 20 Studenten der Fahrzeugtechnik hinsichtlich Attraktivität, Innovativität und Balance bewertet. Im Einklang mit den Annahmen konnte gezeigt werden, dass sehr neuartiges Design von den designungeschulten Probanden als weniger attraktiv bewertet wird als von Betrachtern eines Designstudienganges. In Studie IV wurden neben den Ästhetikbewertungen zusätzlich das Blickverhal-ten und der affektiver Zustand der Versuchsteilnehmer in einem Messwiederholungs-design mit einer zwischengelagerten Phase elaborierter Designbewertung, in welcher der in Studie II geprüfte Fragebogen eingesetzt wurde, erhoben. An der Laborstudie nahmen je 11 Designer, Ingenieure, und Geisteswissenschaftler teil. Wiederum wurde innovatives Design von den designungeschulten Gruppen als weniger attraktiv bewertet. Dieser Unterschied reduzierte sich jedoch nach wiederholter Bewertung der Modelle. Die Manifestation expertisebedingten Blickverhaltens konnte nicht beobach-tet werden, wie auch die durch eine angenommene bessere Bewältigung einherge-hende positivere Stimmung oder höhere Zufriedenheit in der Expertengruppe. Gemeinsam mit den Befunden aus den Studien II und III wurde deutlich, dass Designausbildung und, noch ausgeprägter, Designexpertise neben einer höheren Attraktivitätsbewertung innovativen Designs auch zu einer differenzierteren Beurtei-lung von Innovativität führt. Dies wurde mit der Erweiterung des mentalen Schemas für Fahrzeuge durch die Beschäftigung mit vielfältigen Modellvarianten bereits während des Studiums interpretiert. Es wurden Hinweise auf eine stilbezogene, elaboriertere Verarbeitung von Fahrzeugdesign durch designgeschulte Betrachter beobachtet sowie eine mit Expertise einhergehende Autonomität ästhetischer Urteile als Ausdruck einer hohen ästhetischen Entwicklungsstufe (Parsons, 1987). Mit diesen bei unterschiedlichen Stichproben beobachteten, stabilen expertisebedingten Bewer-tungsunterschieden wurde eine begründete Basis für die geforderte Sensibilisierung für ästhetische Kundenbedürfnisse im Gestaltungsprozess geschaffen. Der in dieser Arbeit entwickelte Fragebogen kann hierbei für eine elaborierte Messung von Fahrzeugdesignpräferenzen, zum Vergleich der ästhetischen Wirkung mit den intendierten Markenwerten sowie für die Diskussion von Nutzereindrücken eingesetzt werden. Die Ergebnisse der vorliegenden Arbeiten tragen somit zur Erweiterung und Präzisierung des theoretischen Verständnisses von Ästhetikbewertungen bei und lassen sich gleichzeitig in die Praxis der Designausbildung und des Designprozesses übertragen. N2 - Car designers are experts in creating car exteriors that transport a brand’s identity by giving a form to its values which has to appeal to a multitude of customers (Giannini & Monti, 2003; Karjalainen, 2002). In this process of translating values into forms it is quintessential to apprehend the customers’ requirements, as the designers understanding of these needs and thus of the design problem itself has a major impact on the quality of the design (Ulrich, 2011). One basis for this apprehension is shared contextual knowledge stemming from a successful interaction between the designer and the user (Lee, Popovich, Blackler & Lee, 2009). Unfortunately, there often is no direct exchange between designers and users (Zeisel, 2006). What is more, findings from research on the fine arts and product aesthetics prove that acquiring design knowledge and aesthetic expertise distinctly alters one’s cognitive processing of aesthetic objects, which also manifests in one’s perception, assessment, and behaviour. One should also expect experts’ preferential assessments to differ from the ones of users as far as aesthetic assessment is concerned. Considering these propositions, the goal of this doctoral thesis was to systematically examine these expertise-induced differences between design experts and laymen in perceiving and assessing automotive design. This thesis also contibutes to furthering the interaction between designers and users by establishing a shared knowledge basis and does so by analyzing the perception, processing, and assessment of car design by designers and laymen. Theoretical assumptions are based on the model of aesthetic appreciation by Leder, Belke, Oeberst and Augustin (2004), which provides detailed but hitherto untested assumptions on how experts and laymen differ in their processing of aesthetic objects. The thesis first focussed on examining the expertiseinduced differences in describing and assessing car design available „in the wild“, i.e. on the market. This and the lexical link between customers’ descriptive attributes and brand values as intended by the car companies were tested in two studies: Study I collected descriptive attributes by using Kelly’s (1955) method of triadic comparions. It also tested the assumption that experts verbalise more productively, generate a higher ratio of symbol-related to form-related attributes and are more homogenous in their use of attributes. In this study, 20 experts and 20 laymen were presented four cars and were to describe the differences between them using self-chosen adjectives. Contrary to the initial assumption, both groups used similar attributes and did thus also not differ in the ratio of symbol-related and form-related attributes. The attributes generated in this study were matched to the collected and categorised values of ten brands using a prototype approach (cp. Amelang & Zielinski, 2002), which resulted in six scales for covering the aesthetic impression of cars. Study II tested these scales for consistency on 83 designers and students of design and 98 design laymen in an online questionnaire. In addition, first predictions were derived from the model by Leder et al. (2004) and tested by comparing these two groups regarding their assessment of four cars on the scales that had shown a high level of internal consistency (attractiveness, dynamics, progressiveness and quality) as well as regarding their overall aesthetic appreciation, response time, and affinity for cars. In this study, the experts were more radical in their assessments, took more time working in the tasks, and cherished cars more than the laymen. The second focus of this work was to combine the assumptions of the model by Leder et al. (2004) and the postulations on how the characteristics of aesthetic objects influence aesthetic assessments (Berlyne, 1971; Martindale, 1988; Silvia, 2005b): Inhowfar do market-relevant characteristics such as innovativeness affect expertise-induced assessment of design? Study III and IV used line art models that were systematically graduated for innovativeness and balance to answer this question. In study III, 18 design students and 20 engineering students assessed these models in an online questionnaire regarding attractiveness, innovativeness, and balance. The results were in line with the assumptions and showed that laymen rated highly innovative design less attractive than experts. Study IV collected data on the aesthetic assessment, gaze behavior, and the participants’ affective state in a repeated measures design that included an intermediary phase of elaborately assessing design by using the questionnaire developed in study II. The sample consisted of 11 designers, 11 engineers, and 11 humanities scholars. Although highly innovative design – as in study III – was rated less attractive by the laymen, repeated measurement decreased this group difference. The study assumed but could not show effects of expertise-induced gaze behaviour, and an expertise-induced better coping with the task resulting in a greater satisfaction with one’s task performance. The findings of this thesis demonstrate that experience with design and – even more pronounced – expertise in this field result in a greater appreciation for innovative design and a more nuanced assessment of innovativeness. Probably, designers constantly enhance their mental schema due to being confronted with various variations of and solutions for a design problem. The studies suggest that experts process car design in a more style-related, elaborate manner and also that designers, due to their more advanced aesthetic level of development (Parsons, 1987) and expertise, are more autonomous in their assessment. These stable expertise-induced differences in assessment between laymen and experts could be demonstrated for various samples. Thus, they are a valid basis for dealing more sensitively with customers’ requirements in the design process. The questionnaire developed in this thesis can be applied to measure design preferences in detail, to compare the aesthetic impact to the intended brand statement, and to discuss users’ impressions. To conclude, the results presented in this thesis contribute to the theory of aesthetic assessment in providing a more precise understanding of aesthetic assessments and can also be applied to design education and design processes.

T1 - Visual and linguistic cues to graspable objects JF - Experimental brain research N2 - Two experiments investigated (1) how activation of manual affordances is triggered by visual and linguistic cues to manipulable objects and (2) whether graspable object parts play a special role in this process. Participants pressed a key to categorize manipulable target objects copresented with manipulable distractor objects on a computer screen. Three factors were varied in Experiment 1: (1) the target's and (2) the distractor's handles' orientation congruency with the lateral manual response and (3) the Visual Focus on one of the objects. In Experiment 2, a linguistic cue factor was added to these three factors-participants heard the name of one of the two objects prior to the target display onset. Analysis of participants' motor and oculomotor behaviour confirmed that perceptual and linguistic cues potentiated activation of grasp affordances. Both target- and distractor-related affordance effects were modulated by the presence of visual and linguistic cues. However, a differential visual attention mechanism subserved activation of compatibility effects associated with target and distractor objects. We also registered an independent implicit attention attraction effect from objects' handles, suggesting that graspable parts automatically attract attention during object viewing. This effect was further amplified by visual but not linguistic cues, thus providing initial evidence for a recent hypothesis about differential roles of visual and linguistic information in potentiating stable and variable affordances (Borghi in Language and action in cognitive neuroscience. Psychology Press, London, 2012).

T1 - Rehabilitationsbedarf bei Hausarztpatienten mit psychischen Störungen JF - Die Rehabilitation : Zeitschrift für Praxis und Forschung in der Rehabilitation N2 - Hintergrund: Rehabilitationsmedizin ist nach § 2 und § 26 SGB IX die medizinische Spezialdisziplin zur Vorbeugung, Diagnostik und Behandlung chronischer Erkrankungen. Dies betrifft in besonderem Maße psychische Erkrankungen. Die Behandlung chronischer Erkrankungen erfordert in der Regel eine komplexe und multimodale Langzeitbetreuung, bei der niedergelassenen Ärzten eine zentrale Rolle zukommt. Allerdings gibt es bislang nur wenig ausgearbeitete Konzepte zu den rehabilitationsmedizinischen Aufgaben niedergelassener Ärzte und den ihnen zur Verfügung stehenden diesbezüglichen Behandlungsoptionen. Methoden: Zur Klärung der Frage, welche Rolle rehamedizinische Aspekte in der Hausarztpraxis haben, wurden im ersten Schritt 40 niedergelassene Ärzte zum geschätzten Anteil chronisch psychisch kranker Patienten in ihrer Praxis befragt. Im zweiten Schritt wurden 1 451 Patienten im Alter von 18 bis 60 Jahren mittels des WHO-5-Screenings zum psychischen Wohlbefinden, dem IMET-Fragebogen zu Teilhabestörungen, der Burvillskala zur Multimorbidität und Fragen zum psychischen Erkrankungsstatus und Arbeitsstatus untersucht. Ergebnisse:Im Durchschnitt schätzten die Hausärzte den Anteil ihrer Patienten mit psychischen Erkrankungen auf 41,9% (SD=18,2; Range 15-90%).Von den Patienten gaben 46,5% an, unter psychischen Beschwerden zu leiden. 38,3% der Patienten sagten, dass die Probleme bereits seit 6 Monaten oder länger bestehen (chronisch), und 26,9% erklärten, dass sie die Beschwerden in den letzten 6 Monaten durchgängig erlebt haben (persistierend). Insgesamt litten 29,7% der 18- bis 60-jährigen Hausarztpatienten unter chronischen psychischen Beschwerden mit zusätzlich relevanten Teilhabestörungen. Schlussfolgerungen: Patienten mit chronischen psychischen Problemen und Teilhabestörungen sind in Praxen niedergelassener Ärzte häufig anzutreffen. Niedergelassene Ärzte und insbesondere Hausärzte sind demnach zu einem wesentlichen Teil ihrer Tätigkeit als Rehabilitationsmediziner anzusehen. In ihren Händen liegt die Diagnostik, Behandlung, Koordinierung und Langzeitführung der chronisch Kranken, wie auch die sozialmedizinische Betreuung, von der Feststellung einer Arbeitsunfähigkeit bis hin zur Einleitung stationärer Rehamaßnahmen. Die Bedeutung der niedergelassenen Ärzte im Rehaprozess verdient organisatorisch wie wissenschaftlich mehr Aufmerksamkeit.

The prevalence of job-anxiety within a working population is not known. Identifying individuals who would benefit from intervention might be useful. Aims To investigate job-anxiety in employees not undergoing treatment for mental health illness, firstly by assessing the level of job-anxiety and work-related avoidance tendencies in a working sample, and secondly by testing whether job-anxiety is distinguishable from trait-anxiety. Methods Cross-sectional survey of a convenience sample obtained through personal contact distribution. Employees from different professional settings completed an anonymous questionnaire and provided information on their employment status. The State-Trait-Anxiety Inventory (STAI-T) was used to measure trait-anxiety and the Job-Anxiety-Scale (JAS) was used to assess job (state) anxiety. Results There was a 69% response rate (240 responses); 188 responses were available for analysis of whom 62% were women. There were no employees with high trait-anxiety. Ten employees (5%) reported increased job-anxiety and of these nine employees reported high 'tendencies of avoidance and workplace absence'. Avoidance was most often accompanied by the comorbid job-anxieties 'job-related social anxiety', 'fear of changes at work' and 'fears of existence', 'anticipatory' and 'conditioned' job-anxiety and 'panic symptoms'. Conclusions In this sample, self-reported job-anxiety appeared as a specific type of anxiety as opposed to trait-anxiety. In the workplace job-anxiety can present as job-avoidance and sickness absence and should be distinguished from trait-anxiety. In practice, employers and occupational health practitioners should be aware of those employees prone to sickness absence.

T1 - Serial and parallel processes in eye movement control - current controversies and future directions T2 - The quarterly journal of experimental psychology N2 - In this editorial for the Special Issue on Serial and Parallel Processing in Reading we explore the background to the current debate concerning whether the word recognition processes in reading are strictly serialsequential or take place in an overlapping parallel fashion. We consider the history of the controversy and some of the underlying assumptions, together with an analysis of the types of evidence and arguments that have been adduced to both sides of the debate, concluding that both accounts necessarily presuppose some weakening of, or elasticity in, the eyemind assumption. We then consider future directions, both for reading research and for scene viewing, and wrap up the editorial with a brief overview of the following articles and their conclusions.

Consistent with the theory, pubertal timing of the girls (but not of the boys) was predicted by the quality of parental relations in childhood, and pubertal timing of the girls (but not of the boys) was a significant predictor of the age at first intercourse. The results suggest that there are different developmental pathways for girls and boys with respect to the predictions of the evolutionary theory of socialization of Belsky et al.

Additive effects among these factors have been taken as evidence for discrete-stage models of word reading. We present evidence from linear mixed-model analyses applied to 2 lexical decision experiments indicating that apparent additive effects can be the product of aggregating over- and underadditive interaction effects that are modulated by recent trial history, particularly the lexical status and stimulus quality of the previous trial's target. Even a simple practice effect expressed as improved response speed across trials was powerfully modulated by the nature of the previous target item. These results suggest that additivity and interaction between factors may reflect trial-to-trial variation in stimulus representations and decision processes rather than fundamental differences in processing architecture.

T1 - Overweight people have low levels of implicit weight bias, but overweight nations have high levels of implicit weight bias JF - PLoS one N2 - Although a greater degree of personal obesity is associated with weaker negativity toward overweight people on both explicit (i.e., self-report) and implicit (i.e., indirect behavioral) measures, overweight people still prefer thin people on average. We investigated whether the national and cultural context - particularly the national prevalence of obesity predicts attitudes toward overweight people independent of personal identity and weight status. Data were collected from a total sample of 338,121 citizens from 71 nations in 22 different languages on the Project Implicit website (https://implicit.harvard.edu/) between May 2006 and October 2010. We investigated the relationship of the explicit and implicit weight bias with the obesity both at the individual (i.e., across individuals) and national (i.e., across nations) level. Explicit weight bias was assessed with self-reported preference between overweight and thin people; implicit weight bias was measured with the Implicit Association Test (IAT). The national estimates of explicit and implicit weight bias were obtained by averaging the individual scores for each nation. Obesity at the individual level was defined as Body Mass Index (BMI) scores, whereas obesity at the national level was defined as three national weight indicators (national BMI, national percentage of overweight and underweight people) obtained from publicly available databases. Across individuals, greater degree of obesity was associated with weaker implicit negativity toward overweight people compared to thin people. Across nations, in contrast, a greater degree of national obesity was associated with stronger implicit negativity toward overweight people compared to thin people. This result indicates a different relationship between obesity and implicit weight bias at the individual and national levels.

In 3 eye-tracking experiments, participants read silently sentences that allow for 2 possible syntactic interpretations when there is no comma or other cue specifying which interpretation should be taken. In Experiments 1 and 2, participants heard a low-pass filtered auditory version of the sentence, which provided a prosodic boundary cue prior to each sentence. In Experiment 1, we found that the boundary cue helped syntactic disambiguation after the cue and led to longer fixation durations on regions right before the cue than on identical regions without prosodic boundary information. In Experiments 2 and 3, we used a gaze-contingent display-change paradigm to manipulate the parafoveal visibility of the first constituent character of the target word after the disambiguating position. Results of Experiment 2 showed that previewing the first character significantly reduced the reading time of the target word, but this preview benefit was greatly reduced when the prosodic boundary cue was introduced at this position. In Experiment 3, instead of the acoustic cues, a visually presented comma was inserted at the disambiguating position in each sentence. Results showed that the comma effect on lexical processing was essentially the same as the effect of prosodic boundary cue. These findings demonstrate that processing a prosodic boundary could impair the processing of parafoveal information during sentence reading.

The present study aims to replicate recent findings using different genetic variants and measures of early adversity assessed both prospectively and retrospectively. Data were collected in the context of an ongoing epidemiological cohort study following the outcome of early risk factors from birth into adulthood. 300 participants (137 males, 163 females) were genotyped for four CRHR1 SNPs (rs7209436, rs110402, rs242924, and rs17689882) and completed the Beck Depression Inventory at ages 19, 22 and 23 years. Childhood adversity was assessed using the Childhood Trauma Questionnaire and by a standardized parent interview yielding an index of family adversity. Our results indicate that CRHR1 and childhood adversity interacted to predict depressive symptoms in young adults. Specifically, we found that the impact of childhood maltreatment on adult depressive symptoms was significantly higher in individuals (i) with two copies of the CRHR1 TAT haplotype, and (ii) homozygous for the G allele of rs17689882. The interaction was demonstrated for exposure to childhood maltreatment as assessed by retrospective self-report, but not to prospectively ascertain objective family adversity. The present study partially replicates recent findings of a CRHR1 by childhood adversity interaction with regard to adult depression highlighting the subjective characteristics of the environmental pathogen that is operative in this interaction.

Here we investigate the consequences of this functional segregation for the control of fixation durations during scene viewing. Using gaze-contingent displays, we applied high-pass or low-pass filters to either the central or the peripheral visual field and compared eye-movement patterns with an unfiltered control condition. In contrast with predictions from functional segregation, fixation durations were unaffected when the critical information for vision was strongly attenuated (foveal low-pass and peripheral high-pass filtering); fixation durations increased, however, when useful information was left mostly intact by the filter (foveal high-pass and peripheral low-pass filtering). These patterns of results are difficult to explain under the assumption that fixation durations are controlled by foveal processing difficulty. As an alternative explanation, we developed the hypothesis that the interaction of foveal and peripheral processing controls fixation duration. To investigate the viability of this explanation, we implemented a computational model with two compartments, approximating spatial aspects of processing by foveal and peripheral activations that change according to a small set of dynamical rules. The model reproduced distributions of fixation durations from all experimental conditions by variation of few parameters that were affected by specific filtering conditions.

A1 - Engbert, Ralf T1 - Differentiating between verbal and spatial encoding using eye-movement recordings JF - The quarterly journal of experimental psychology N2 - Visual information processing is guided by an active mechanism generating saccadic eye movements to salient stimuli. Here we investigate the specific contribution of saccades to memory encoding of verbal and spatial properties in a serial recall task. In the first experiment, participants moved their eyes freely without specific instruction. We demonstrate the existence of qualitative differences in eye-movement strategies during verbal and spatial memory encoding. While verbal memory encoding was characterized by shifting the gaze to the to-be-encoded stimuli, saccadic activity was suppressed during spatial encoding. In the second experiment, participants were required to suppress saccades by fixating centrally during encoding or to make precise saccades onto the memory items. Active suppression of saccades had no effect on memory performance, but tracking the upcoming stimuli decreased memory performance dramatically in both tasks, indicating a resource bottleneck between display-controlled saccadic control and memory encoding. We conclude that optimized encoding strategies for verbal and spatial features are underlying memory performance in serial recall, but such strategies work on an involuntary level only and do not support memory encoding when they are explicitly required by the task.

The program has been designed according to insights on the typical and atypical development of mathematical abilities. The learning process is supported through multimodal cues, which encode different properties of numbers. To offer optimal learning conditions, a user model completes the program and allows flexible adaptation to a child's individual learning and knowledge profile. Thirty-two children with difficulties in learning mathematics completed the 6-12-weeks computer training. The children played the game for 20 min per day for 5 days a week. The training effects were evaluated using neuropsychological tests. Generally, children benefited significantly from the training regarding number representation and arithmetic operations. Furthermore, children liked to play with the program and reported that the training improved their mathematical abilities.

Correlation between food familiarity and actual preference JF - Zeitschrift für Gesundheitspsychologie N2 - The preference for fruits and vegetables is the main predictor for the longtime healthy eating behavior. There are many factors which affect the development of food preferences. The familiarity with different foods seems to be a special aspect associated with the corresponding preference. To establish a preference for fruits and vegetables during early childhood, we need to know more about the factors that affect this preference development. So far, research has mostly concentrated on the food intake and less on the corresponding preference. Additionally, it is often based on studies of the mere-exposure effect or on older children and their ability to label fruits and vegetables correctly. Findings about the level of food familiarity in young children and its relation to the actual food preference are still missing. Our study focuses on different aspects of food familiarity as well as on their relationship to the child's preference and presents results from 213 children aged 2 to 10 years. Using standardized photos, the food preference was measured with a computer-based method that ran automatically without influence from parents or interviewer. The children knew fewer of the presented vegetables (66 %) than fruits or sweets (78 % each). About the same number of vegetables (63 %) had already been tasted by the children and were considered tasty. Only 48 % of the presented vegetables were named correctly - an ability that increases in older children. Concerning the relationship between the familiarity with vegetables and their preference, the different familiarity aspects showed that vegetables of lower preference were less often recognized, tasted, considered tasty, or named correctly.

JF - Appetite : multidisciplinary research on eating and drinking N2 - Background: Research concerning children's emotional eating behavior has shown its negative impact on weight-related problems. Taking the model of Birch and Davison (2001) into account, we focus on the role of maternal feeding behavior on the association between emotional eating of the mother and the child. Methods: 482 mothers and their children participated in this cross-sectional study. The mothers were asked about their feeding strategies, their children's and their own emotional eating and weight. We tested a structural equation model for different feeding strategies. Results: In addition to an expected direct association between the mother's and child's emotional eating, the maternal feeding strategies are related to the child's eating behavior. A higher maternal restriction of food or its monitoring was associated with a higher level of children's emotional eating, while allowing the child more control about their eating was linked to less pronounced emotional eating behavior. Conclusions: The results highlight the relevance of maternal feeding behavior on emotional eating in childhood. In terms of preventing weight-related problems, the findings indicate the necessity of training parents in allowing their children more control and avoiding the restriction of food.

Recent embodied theories suggest that analog number representations are based on previous sensory experiences and constitute therefore a common magnitude metric shared by multiple domains. Here we demonstrate the existence of a cross-modal semantic distance effect between symbolic and tactile numerosities. Participants received tactile stimulations of different amounts of fingers while reading Arabic digits and indicated verbally whether the amount of stimulated fingers was different from the simultaneously presented digit or not. The larger the semantic distance was between the two numerosities, the faster and more accurate participants made their judgments. This cross-modal numerosity distance effect suggests a direct connection between tactile sensations and the concept of numerical magnitude. A second experiment replicated the interaction between symbolic and tactile numerosities and showed that this effect is not modulated by the participants' finger counting habits. Taken together, our data provide novel evidence for a shared metric for symbolic and tactile numerosities as an instance of an embodied representation of numbers.

Participants were asked about both victimization by, and perpetration of, sexual aggression since the age of 14. Both same-sex and heterosexual victim-perpetrator constellations were examined. Prevalence rates were established for different victim-perpetrator relationships (partners, acquaintances, strangers) and for incidents involving alcohol consumption by one or both partners. The overall perpetration rate was 13.2%, for men and 7.6% for women. The overall victimization rate was 35.9% for women and 19.4% for men. A disparity between victimization and perpetration reports was found for both men and women. Perpetration and victimization rates were highest among participants who had sexual contacts with both opposite-sex and same-sex partners. Sexual aggression and victimization rates were higher between current or former partners and acquaintances than between strangers. Alcohol consumption by one or both partners was involved in almost 75% of all victimization and almost 70% of all perpetration incidents.

They provide insights into IPV from nine different cultures - China, Germany, Italy, Japan, Mexico, Northern Ireland, Sweden, Turkey, and the United States - from scholars in the fields of psychology, gender studies, political science, and economics. The first three papers look at how widespread the experience of IPV is among different groups of women, examine selected risk factors associated with heightened vulnerability to victimization, and discuss consequences of intimate partner victimization. Another two papers place the problem of IPV in the wider context of societal perceptions and attitudes about victims and perpetrators of IPV in different countries, whereas the last paper examines the role of individual differences in the management of emotions in the escalation or de-escalation of relationship conflict. In combination, the papers highlight the interplay between the macro level of social and cultural norms condoning the use of violence, the micro level of family relations and construction of couple relationships, and the individual level of attitudes and behaviors that precipitate IPV.

T1 - How preview space/time translates into preview cost/benefit for fixation durations during reading JF - The quarterly journal of experimental psychology N2 - Eye-movement control during reading depends on foveal and parafoveal information. If the parafoveal preview of the next word is suppressed, reading is less efficient. A linear mixed model (LMM) reanalysis of McDonald (2006) confirmed his observation that preview benefit may be limited to parafoveal words that have been selected as the saccade target. Going beyond the original analyses, in the same LMM, we examined how the preview effect (i.e., the difference in single-fixation duration, SFD, between random-letter and identical preview) depends on the gaze duration on the pretarget word and on the amplitude of the saccade moving the eye onto the target word. There were two key results: (a) The shorter the saccade amplitude (i.e., the larger preview space), the shorter a subsequent SFD with an identical preview; this association was not observed with a random-letter preview. (b) However, the longer the gaze duration on the pretarget word, the longer the subsequent SFD on the target, with the difference between random-letter string and identical previews increasing with preview time. A third patternincreasing cost of a random-letter string in the parafovea associated with shorter saccade amplitudeswas observed for target gaze durations. Thus, LMMs revealed that preview effects, which are typically summarized under preview benefit, are a complex mixture of preview cost and preview benefit and vary with preview space and preview time. The consequence for reading is that parafoveal preview may not only facilitate, but also interfere with lexical access.
