The fastest components of these miniature eye movements are microsaccades, which can be observed about once per second. Recent studies demonstrated that microsaccades are linked to covert shifts of visual attention [e.g., Engbert & Kliegl (2003), Vision Res 43:1035-1045]. Here,we generalized this finding in two ways. First, we used peripheral cues, rather than the centrally presented cues of earlier studies. Second, we spatially cued attention in vision and audition to visual and auditory targets. An analysis of microsaccade responses revealed an equivalent impact of visual and auditory cues on microsaccade-rate signature (i.e., an initial inhibition followed by an overshoot and a final return to the pre-cue baseline rate). With visual cues or visual targets,microsaccades were briefly aligned with cue direction and then opposite to cue direction during the overshoot epoch, probably as a result of an inhibition of an automatic saccade to the peripheral cue. With left auditory cues and auditory targets microsaccades oriented in cue direction. Thus, microsaccades can be used to study crossmodal integration of sensory information and to map the time course of saccade preparation during covert shifts of visual and auditory attention.

It would be desirable to have other predictors that are easier to collect and objective in nature if these predictors were capable of capturing the information stored in predictability. This paper contributes to this discussion by testing a possible predictor: conditional co-occurrence probability. This measure is a simple statistical representation of the relatedness of the current word to its context, based only on word co-occurrence patterns in data taken from the Internet. In the regression analyses, conditional co-occurrence probability acts like lexical frequency in predicting fixation durations, and its addition does not greatly improve the model fits. We conclude that readers do not seem to use the information contained within conditional co-occurrence probability during reading for meaning, and that similar simple measures of semantic relatedness are unlikely to be able to replace predictability as a predictor for fixation durations.

When the meaning of a concrete content word is being acquired, the learner is confronted with stimuli of various modalities related to the word's meaning. This comes to be stored as sensory knowledge about the object. It is further postulated that there is a conceptual domain remote from the mechanisms of perception, which is often referred to as functional knowledge or verbal semantics. There is a large body of neuropsychological literature trying to establish how much sensory and functional semantics is needed to access a name, and whether the relative contribution of these types of knowledge is the same for all categories of objects. Another controversial issue is whether naming requires access to semantic knowledge, or whether object names can be accessed directly from vision without the intervention of semantics, as is generally accepted for written word naming. Some support for this assumption seems to come from cases of so-called non-optic aphasia, a condition in which patients can name from visual presentation only but not from any other modality of presentation such as auditory, verbal, tactile, etc. In optic aphasia, a condition far better established, naming is possible from all modalities except vision. Aims: The aim of this paper is to draw attention to the first case description of non-optic or negative optic aphasia described by Wolff (1897, 1904). Methods Procedures: The case describes the results of a re-examination of Voit, who was seen by several neurologists in the course of a decade in classical aphasiology. The patient demonstrated anomia in oral but not in written naming of objects in view. Wolff's examination involves extensive testing of semantic processing in several modalities, especially with respect to the status of functional and sensory semantic features Outcomes Results: The re-examination of patient Voit by Wolff in 1897 with new procedures revealed a specific impairment in processing sensory knowledge, while functional knowledge of objects was relatively preserved. This led to a naming impairment in all modalities of presentation except the visual one. Using more refined tasks, Wolff also demonstrated receptive impairments, in contrast to previous researchers who had concluded that the impairment was restricted to oral production. Conclusions: Although Wolff's (1904) case of negative optic aphasia has been almost completely forgotten (but see Bartels Wallesch, 1996), it is astonishingly modern in its conceptual approach and in the central questions it addresses on the mechanisms involved in the process of naming and on the structure of the semantic system. As is usual in classical cases, the methodology may appear less stringent than in most contemporary work, but the approach was brilliant.

Children start to succeed on complementation tasks in which they are required to report the content of an embedded clause in the second half of the fourth year. Traditional ToM tasks test the child’s ability to predict that a person who is holding a false belief (FB) about a situation will act "falsely". In these task, children do not represent FBs until the age of 4 years. According the linguistic determinism hypothesis, only the unique syntax of complement sentences provides the format for representing FBs. However, experiments measuring children’s looking behavior instead of their explicit predictions provided evidence that already 2-year olds possess an implicit ToM. This dissertation examined the question of whether there is an interrelation also between implicit ToM and the comprehension of complement sentences in typically developing German preschoolers. Two studies were conducted. In a correlational study (Study 1 ), 3-year-old children’s performance on a traditional (explicit) FB task, on an implicit FB task and on language tasks measuring children’s comprehension of tensed sentential complements were collected and tested for their interdependence. Eye-tracking methodology was used to assess implicit ToM by measuring participants’ spontaneous anticipatory eye movements while they were watching FB movies. Two central findings emerged. First, predictive looking (implicit ToM) was not correlated with complement mastery, although both measures were associated with explicit FB task performance. This pattern of results suggests that explicit, but not implicit ToM is language dependent. Second, as a group, 3-year-olds did not display implicit FB understanding. That is, previous findings on a precocious reasoning ability could not be replicated. This indicates that the characteristics of predictive looking tasks play a role for the elicitation of implicit FB understanding as the current task was completely nonverbal and as complex as traditional FB tasks. Study 2 took a methodological approach by investigating whether children display an earlier comprehension of sentential complements when using the same means of measurement as used in experimental tasks tapping implicit ToM, namely anticipatory looking. Two experiments were conducted. 3-year-olds were confronted either with a complement sentence expressing the protagonist’s FB (Exp. 1) or with a complex sentence expressing the protagonist’s belief without giving any information about the truth/ falsity of the belief (Exp. 2). Afterwards, their expectations about the protagonist’s future behavior were measured. Overall, implicit measures reveal no considerably earlier understanding of sentential complementation. Whereas 3-year-olds did not display a comprehension of complex sentences if these embedded a false proposition, children from 3;9 years on were proficient in processing complement sentences if the truth value of the embedded proposition could not be evaluated. This pattern of results suggests that (1) the linguistic expression of a person’s FB does not elicit implicit FB understanding and that (2) the assessment of the purely syntactic understanding of complement sentences is affected by competing reality information. In conclusion, this dissertation found no evidence that the implicit ToM is related to the comprehension of sentential complementation. The findings suggest that implicit ToM might be based on nonlinguistic processes. Results are discussed in the light of recently proposed dual-process models that assume two cognitive mechanisms that account for different levels of ToM task performance. N2 - Zahlreiche Studien legen nahe, dass der Erwerb finiter Komplementsatzstrukturen eine Voraussetzung für die Entwicklung einer Theory of Mind (ToM) ist. Kinder beginnen in circa der zweiten Hälfte ihres 4. Lebensjahres Komplementsatzverständnisaufgaben zu lösen, die eine Wiedergabe des Komplementsatzes erfordern. Die ToM wird klassischerweise als erworben bezeichnet, wenn ein Kind korrekt vorhersagen kann, dass eine Person, die eine falsche Überzeugung hat, entsprechend "falsch" handeln wird. Es ist bekannt, dass sich diese Fähigkeit bei Kindern mit circa 4 Jahren entwickelt. Gemäß der Hypothese des linguistischen Determinismus liefert die syntaktische Komplexität von Komplementsatzstrukturen das Format, um falsche Überzeugungen mental zu repräsentieren. In ToM Aufgaben, die erfassen, wo Kinder eine zukünfige Handlung einer fehlinformierten Person antizipieren, konnte allerdings bereits schon bei 2-Jährigen das Verstehen falscher Überzeugungen nachgewiesen werden. Diese frühe Fähigkeit wird auch implizite ToM genannt, da diese Art der Aufgabe keine bewusste Entscheidung verlangt. Die vorliegende Dissertation untersucht erstmalig im Deutschen, ob der Zusammenhang zwischen dem Verstehen von Komplementsatzstrukturen und ToM auch für diese implizite Fähigkeit gilt. Zwei Studien wurden durchgeführt. In Studie 1 wurden die Leistungen von 3-Jährigen in einer klassischen (expliziten) ToM Aufgabe, einer impliziten ToM Aufgabe und in Komplementsatzverständnisaufgaben erhoben und auf korrelative Zusammenhänge hin getestet. Dabei wurde mittels eines Eye-Trackers das antizipative Blickverhalten gemessen und somit auf das Vorhandensein einer impliziten ToM geschlossen. Die Leistungen in den Sprachaufgaben korrelierten nicht mit den Blickdaten, obwohl beide Maße mit den Leistungen in der expliziten ToM Aufgabe in Beziehung standen. Unerwarteterweise konnte jedoch generell kein implizites Verstehen falscher Überzeugungen bei 3-jährigen nachgewiesen werden. Da die implizite ToM Aufgabe nichtsprachlich war, wird der Einfluss von Aufgabeneigenschaften auf die Elizitierung von impliziter ToM diskutiert. Studie 2 untersuchte, ob 3-Jährige ein früheres, implizites Verstehen von Komplementsatzstrukturen in Aufgaben zeigen, in denen antizipatorische Blicke anstelle von expliziten Antworten gemessen werden und damit das gleiche Maß verwendet wird wie in impliziten ToM Aufgaben. Zwei Experimente wurden durchgeführt. Der präsentierte Komplementsatz drückte entweder eine falsche Überzeugung des Protagonisten aus (Exp. 1) oder eine Überzeugung, deren Wahrheitsgehalt nicht bestimmt wurde (Exp. 2). Während bei 3-Jährigen kein Verstehen von Komplementsatzstrukturen, die eine falsche Proposition enthielten, nachgewiesen werden konnte, zeigten Kinder ab einem Alter von 3;9 Jahren, dass sie den komplexen Satz verarbeiten, wenn dieser keine falsche Proposition beinhaltet. Dieses Ergebnismuster spricht dafür, dass (1) der sprachliche Ausdruck einer falschen Überzeugung die implizite ToM nicht elizitieren kann und dass (2) das Erfassen des rein syntaktischen Verstehens durch zusätzliche Realitätsinformation beeinträchtigt wird. Zusammenfassend konnte in der vorliegenden Arbeit kein Hinweis dafür gefunden werden, dass die implizite ToM in gleicher Weise wie die explizite ToM mit dem Verstehen von Komplementsatzstrukturen einhergeht. Die Ergebnisse legen nahe, dass vielmehr nonlinguistische Faktoren bei der Entwicklung einer impliziten ToM eine Rolle spielen könnten. Die Resultate werden mit Blick auf aktuelle Zwei-Prozess-Modelle diskutiert.

The Plenary talks provide a venue for questions of the numerical capacities and human arithmetic (Brian Butterworth), of the theoretical development of cognitive architectures and intelligent virtual agents (Pat Langley), of categorizations induced by linguistic constructions (Claudia Maienborn), and of a cross-level account of the “Self as a complex system“ (Paul Thagard). KogWis 2010 integrates a wealth of experimental research, cognitive modelling, and conceptual analysis in 5 invited symposia, over 150 individual talks, 6 symposia, and more than 40 poster contributions. Some of the invited symposia reflect local and regional strenghts of research in the Berlin-Brandenburg area: the two largests research fields of the university Cognitive Sciences Area of Excellence in Potsdam are represented by an invited symposium on “Information Structure” by the Special Research Area 632 (“Sonderforschungsbereich”, SFB) of the same name, of Potsdam University and Humboldt-University Berlin, and by a satellite conference of the research group “Mind and Brain Dynamics”. The Berlin School of Mind and Brain at Humboldt-University Berlin takes part with an invited symposium on “Decision Making” from a perspective of cognitive neuroscience and philosophy and the DFG Cluster of Excellence “Languages of Emotion” of Free University presents interdisciplinary research results in an invited symposium on “Symbolising Emotions”.

The present work approaches these questions by investigating the negative particle ne used for sentential negation in Bulgarian and its impact on the overt realisation and the interpretation of imperative inflexion, bound aspectual morphemes and clitic pronouns in child, adult and aphasic language. In contrast to other Slavic languages, Bulgarian negative imperatives (NI) are grammatical only with imperfective verbs. We argue that NI are instantiations of overt aspectual coercion induced by the presence of negation as a temporally sensitive sentential operator. The scope relation between imperative mood, negation, and aspect yields the configuration of the imperfective present which in Bulgarian has to be overtly expressed and prompts the imperfective marking of the predicate. The regular and transparent application of the imperfectivising mechanism relates to the organisation of the TAM categories in Bulgarian which not only promotes the representation of fine perspective shifts but also provides for their distinct morphological expression. Using an elicitation task with NI, we investigated the way 3- and 4-year-old children represent negation in deontic contexts as reflected in their use of aspectually appropriate predicates. Our findings suggest that children are sensitive to the imperfectivity requirement in NI from early on. The imperfectivisation strategies reveal some differences from the target morphological realisation. The relatively low production of target imperfectivised prefixed verbs cannot be explained with morphological processing deficits, but rather indicates that up to the age of five children experience difficulties to apply a progressive view point to accomplishments. Two self-paced reading studies present evidence that neurologically unimpaired Bulgarian speakers profit from the syntactic and prosodic properties of negation during online sentence comprehension. The imperfectivity requirement negation imposes on the predicate speeds up lexical access to imperfective verbs. Similarly, clitic pronouns are more accessible after negation due to the phono-syntactic properties of clitic clusters. As the experimental stimuli do not provide external discourse referents, personal pronouns are parsed as object agreement markers. Without subsequent resolution, personal pronouns appear to be less resource demanding than reflexive clitics. This finding is indicative of the syntax-driven co-reference establishment processes triggered through the lexical specification of reflexive clitics. The results obtained from Bulgarian Broca's aphasics show that they exhibit processing patterns similar to those of the control group. Notwithstanding their slow processing speed, the agrammatic group showed no impairment of negation as reflected by their sensitivity to the aspectual requirements of NI, and to the prosodic constraints on clitic placement. The aphasics were able to parse the structural dependency between mood, negation and aspect as functional categories and to represent it morphologically. The prolonged reaction times (RT) elicited by prefixed verbs indicate increasing processing costs due to the semantic integration of prefixes as perfectivity markers into an overall imperfective construal. This inference is supported by the slower RT to reflexive clitics, which undergo a structurally triggered resolution. Evaluated against cross-linguistic findings, the obtained result strongly suggests that aphasic performance with pronouns depends on the interpretation efforts associated with co-reference establishment and varies due to availability of discourse referents. The investigation of normal and agrammatic processing of Bulgarian NI presents support for the hypothesis that the comprehension deficits in Broca's aphasia result from a slowed-down implementation of syntactic operations. The protracted structure building consumes processing resources and causes temporal mismatches with other processes sustaining sentence comprehension. The investigation of the way Bulgarian children and aphasic speakers process NI reveals that both groups are highly sensitive to the imperfective constraint on the aspectual construal imposed by the presence of negation. The imperfective interpretation requires access to morphologically complex verb forms which contain aspectual morphemes with conflicting semantic information – perfective prefixes and imperfective suffixes. Across modalities, both populations exhibit difficulties in processing prefixed imperfectivised verbs which as predicates of negative imperative sentences reflect the inner perspective the speaker and the addressee need to take towards a potentially bounded situation description. N2 - Die schnelle und automatische Natur der Satzverarbeitung wirft Fragen nach der inkrementellen Integration von funktionalen Elementen auf. Wie erfolgt der Zugriff auf die strukturellen, semantischen und prosodischen Informationen der funktionalen Elemente? Wie werden diese Informationen beim Aufbau der syntaktischen Struktur so verknüpft, dass eine wohlgeformte semantische Repräsentation entsteht? Die vorliegende Dissertation widmet sich diesen Fragen durch die Untersuchung der Verarbeitungsmuster von bulgarischen negativen Imperativen (NI) in der Sprache von Kindern, Erwachsenen und Broca-Aphasikern. Die Effekte der Negationspartikel ne auf die Realisierung und die Interpretation von Imperativ- und Aspektmorphologie sowie von klitischen Pronomen werden in Produktions- und online Satzverständnistests untersucht. Im Unterschied zu anderen slawischen Sprachen sind synthetische NI im Bulgarischen mit perfektiven Verben ungrammatisch. Diese Besonderheit wird zunächst durch die aspektuelle Interpretation von NI und die sprachspezifische Organisation des TAM-Systems begründet. Die Aspektrestriktion resultiert aus dem Aspektzwang, den die Negation als temporal sensitiver Operator auslöst. Die Skopusrelation zwischen imperativem Modus, Negation und Aspekt ergibt die temporale Konfiguration von imperfektivem Präsens, die im Bulgarischen morphologisch durch die Imperfektivierung des Prädikats markiert werden muss. Der Wechsel in der aspektuellen Perspektive wird durch einen produktiven und transparenten Imperfektivierungsmechanismus gewährleistet. Der Erwerb von Negation in deontischen Kontexten wurde anhand der Produktion von imperfektiven Prädikaten in einem Elizitationsexperiment mit 3- und 4-jährigen Kindern untersucht. Die Ergebnisse belegen eine frühe Sensitivität für die aspektuelle Wohlgeformtheit der NI. Die Imperfektivierungsstragien zeigen jedoch Abweichungen von der zielsprachlichen morphologischen Realisierung. Die relativ niedrige Produktion von imperfektivierten präfigierten Verben kann nicht durch Defizite in der Morphologieverarbeitung erklärt werden. Die Fehleranalyse verdeutlicht die Schwierigkeiten der Kinder eine Innenperspektive zu potenziell gebundenen Ereignissen einzunehmen, die der zielsprachlichen Interpretation entspräche. Die syntaktischen und prosodischen Effekte der Negation auf die inkrementelle Verarbeitung von Imperativen bei erwachsenen bulgarischen Muttersprachlern wurde in zwei online Leseexperimenten (self-paced reading) untersucht. Die Reaktionszeiten (RT) zeigen, dass die Negation den lexikalischen Zugriff auf imperfektive Verben beschleunigt. In NI wird der Verarbeitungsaufwand für klitische Pronomen auch deutlich reduziert, da die proklitische Negation mit den pronominalen Enklitika eine phono-syntaktisch strikt geordnete Sequenz bildet. Da der experimentelle Kontext keine externen Diskursreferenten bereitstellt, werden klitische Personalpronomen als Objektkongruenzmarker verarbeitet. Dementsprechend elizitieren sie kürzere RT als die reflexiven Klitika, die eine syntaktisch motivierte Resolution auslösen. Abgesehen von der deutlich verlangsamten Geschwindigkeit, weisen die RT der untersuchten Broca-Aphasikern ein mit dem der Kontrollgruppe vergleichbares Muster auf. Die Agrammatiker profitieren vom Aspektzwang sowie von den phono-syntaktischen Restriktionen der klitischen Gruppe in NI. Dieses Ergebnis wird als Evidenz interpretiert, dass keine qualitative Beeinträchtigung in der Verarbeitung der funktionalen Eigenschaften der Negation vorliegt. Die Aphasiker sind in der Lage die strukturell bedingte Interaktion zwischen Modus, Negation und Aspekt zu parsen und morphologisch abzubilden, weisen jedoch längere RT für präfigierte Verben auf, was auf einen erhöhten Interpretationsaufwand hindeutet. Die längeren RT der reflexiven Klitika sprechen auch dafür, dass die Performanz der Broca-Aphasikern eher durch den Resolutionsprozess und durch die Verfügbarkeit von Diskursreferenten bedingt wird. Die Lesezeit-Experimente liefern Evidenz für die Hypothese, dass Verständnisdefizite bei Broca-Aphasie von einer langsamen Implementierung syntaktischer Operationen resultieren. Die Limitierung von Verarbeitungsressourcen verzögert den Strukturaufbau und verursacht zeitliche Diskrepanzen zwischen Prozessen, die die semantische Repräsentation bedingen. Die Untersuchungen zur Verarbeitung von NI bei bulgarischen Kindern und Broca-Aphasikern belegen die hohe Sensitivität beider Gruppen für den Aspektzwang in prohibitiven NI. Die imperfektive Interpretation erfordert Zugang zu morphologisch komplexen Verben mit semantisch widersprüchlichen aspektuellen Affixen – perfektiven Präfixen und imperfektiven Suffixen. Beide Gruppen haben Schwierigkeiten präfigierte imperfektivierte Verben zu verarbeiten. Als Prädikate in NI reflektieren solche komplexe Verben die innere Perspektive, die Sprecher und Hörer in der Repräsentation eines potenziell gebundenen Ereignisses einzunehmen haben.

Three eye-movement data sets based on the reading of Dutch and German unrelated sentences reveal a sizeable, replicable increase in reading times over several words in the beginning and the end of sentences. The data from the paragraphbased English-language Dundee corpus replicate the pattern and also indicate that the increase in inspection times is driven by the visual boundaries of the text organized in lines, rather than by syntactic sentence boundaries. We argue that this effect is independent of several established lexical, contextual and oculomotor predictors of eye-movement behavior. We also provide evidence that the effect of word position-intext has two independent components: a start-up effect arguably caused by a strategic oculomotor program of saccade planning over the line of text, and a wrap-up effect originating in cognitive processes of comprehension and semantic integration.

The visual information recorded is accessed, evaluated and processed. Only by retrieving the meaning of a word from the long-term memory, as well as through the connection and storage of the information about each individual word, is it possible to access the semantic meaning of a sentence. Therefore memory, and here in particular working memory, plays a pivotal role in the basic processes of reading. The following dissertation investigates to what extent different demands on memory and memory capacity have an effect on eye movement behavior while reading. The frequently used paradigm of the reading span task, in which test subjects read and evaluate individual sentences, was used for the experimental review of the research questions. The results speak for the fact that working memory processes have a direct effect on various eye movement measurements. Thus a high working memory load, for example, reduced the perceptual span while reading. The lower the individual working memory capacity of the reader was, the stronger was the influence of the working memory load on the processing of the sentence. N2 - Beim Lesen steuern okulomotorische Prozesse die Blickbewegungen über den Text. Die aufgenommenen visuellen Informationen werden erschlossen, beurteilt und verarbeitet. Erst durch den Abruf der Wortbedeutung aus dem Langzeitgedächtnis, und die Verknüpfung sowie Speicherung der einzelnen Wortinformationen erschließt sich die semantische Bedeutung eines Satzes. Somit stellt das Gedächtnis und hier insbesondere das Arbeitsgedächtnis eines der grundlegenden Prozesse für das Lesen dar. Die vorliegende Dissertation untersucht inwieweit sich unterschiedliche Gedächtnisanforderungen und Gedächtniskapazitäten auf das Blickverhalten während des Lesens auswirken. Für die experimentelle Überprüfung der Forschungsfragen wurde das in der Arbeitsgedächtnisforschung sehr häufig genutzte Paradigma der Lesespannenaufgabe verwendet, bei dem Probanden einzelne Sätze lesen und beurteilen. Die Ergebnisse sprechen für einen direkten Einfluss von Arbeitsgedächtnisprozessen auf verschiedene Blickbewegungsmaße. So reduzierte eine hohe Arbeitsgedächtnisbelastung beispielsweise die perzeptuelle Spanne während des Lesens. Je geringer die individuelle Arbeitsgedächtniskapazität des Lesers war, desto stärker war der Einfluss der Arbeitsgedächtnisbelastung auf die Satzverarbeitung.

T1 - Attention deployment during memorizing and executing complex instructions JF - Experimental brain research N2 - We investigated the mental rehearsal of complex action instructions by recording spontaneous eye movements of healthy adults as they looked at objects on a monitor. Participants heard consecutive instructions, each of the form "move [object] to [location]''. Instructions were only to be executed after a go signal, by manipulating all objects successively with a mouse. Participants re-inspected previously mentioned objects already while listening to further instructions. This rehearsal behavior broke down after 4 instructions, coincident with participants' instruction span, as determined from subsequent execution accuracy. These results suggest that spontaneous eye movements while listening to instructions predict their successful execution.

This issue has persisted because most investigated paradigms generated data compatible with both serial and parallel models. Here, we study eye movements in a sequential scanning task, where stimulus n indicates the position of the next stimulus n + 1. We investigate whether eye movements are controlled by sequential attention shifts when the task requires serial order of processing. Our measures of distributed processing in the form of parafoveal-on-foveal effects, long-range modulations of target selection, and skipping saccades provide evidence against models strictly based on serial attention shifts. We conclude that our results lend support to parallel processing as a strategy for eye movement control.

Participants discriminated gaze-contingent probes that occurred with different spatial and temporal offsets from randomly chosen fixation points during reading. We found that attention was initially focused at fixation and that subsequent defocusing was slower when the fixated word was lower in frequency. Later in a fixation, attention oriented more towards the next saccadic target for high- than for low-frequency words. These results constitute the first report of the time course of the effect of load on attentional engagement and orienting in reading. They are discussed in the context of serial and parallel models of reading.

We addressed these questions experimentally by measuring pupillary responses of 40 participants who listened to a series of Limericks. The Limericks ended with either a semantic, syntactic, rhyme or metric violation. Compared to a control condition without violations, only the rhyme violation condition induced a reliable pupillary response. An anomaly-rating study on the same stimuli showed that all violations were reliably detectable relative to the control condition, but the anomaly induced by rhyme violations was perceived as most severe. Together, our data suggest that rhyme violations in Limericks may induce an emotional response beyond mere anomaly detection.

In our study, we examined self-reported psychological symptoms and chronic mood. Data from a representative sample of 866 elite student-athletes (aged 12-15 years), enrolled in high-performance sport programming in German Elite Schools of Sport, were compared with data from 80 student-athletes from the same schools who have just been deselected from elite sport promotion, and from 432 age-and sex-matched non-sport students from regular schools (without such programming). Anxiety symptoms were least prevalent in female elite student-athletes. In male elite student-athletes, only symptoms of posttraumatic stress were less prevalent than in the other groups. Somatoform symptoms were generally more frequent in athletes, a trend that was significantly pronounced in deselected athletes. Deselected athletes showed an increased risk for psychological symptoms compared with both other groups. Regarding chronic mood, again deselected athletes showed less positive scores. While there was a trend toward high-performance sport being associated with better psychological health at least in girls, preventative programs should take into account that deselection from elite sport programming may be associated with specific risks for mental disorders.

This is underscored by genetic studies that demonstrated associations between melatonin receptor type 2 gene (MTNR1B) polymorphisms and characteristics of type 2 diabetes. We set out to test the hypothesis whether genetic variants at MTNR1B are also relevant for other disease phenotypes within the cardiovascular continuum. We thus investigated single nucleotide polymorphisms (SNPs) of MTNR1B in relation to blood pressure (BP) and cardiac parameters in hypertensive patients. Methods: Patients (n = 605, mean age 56.2 +/- 9.4 years, 82.3% male) with arterial hypertension and cardiac ejection fraction (EF) >= 40% were studied. Cardiac parameters were assessed by echocardiography. Results: The cohort comprised subjects with coronary heart disease (73.1%) and myocardial infarction (48.1%) with a mean EF of 63.7 +/- 8.9%. Analysis of SNPs rs10830962, rs4753426, rs12804291, rs10830963, and rs3781638 revealed two haplotypes 1 and 2 with frequencies of 0.402 and 0.277, respectively. Carriers with haplotype 1 (CTCCC) showed compared to non-carriers a higher mean 24-hour systolic BP (difference BP: 2.4 mm Hg, 95% confidence interval (CI): 0.3 to 4.5 mm Hg, p = 0.023). Haplotype 2 (GCCGA) was significantly related to EF with an absolute increase of 1.8% (CI: 0.45 to 3.14%) in carriers versus non-carriers (p = 0.009). Conclusion: Genetics of MTNR1B point to impact of the melatonin signalling pathway for BP and left ventricular function. This may support the importance of the melatonin system as a potential therapeutic target.

This phenomenon is referred to as postactivation potentiation (PAP) and it was frequently substantiated in original research manuscripts, systematic literature reviews, and meta-analyses. However, there is a lack in the literature regarding precise dose-response relations. This literature review describes the main determinants of PAP effects and additionally presents the state of the art regarding the acute effects of PAP protocols on measures of strength, power, and speed in subelite and elite athletes of different sport disciplines. Furthermore, an attempt is made to demonstrate evidence-based information concerning the design of effective PAP protocols. Methods: Our literature search included the electronic databases Pubmed, SportDiscus, and Google Scholar (1995 - March 2013). In total, 23 studies met the inclusionary criteria for review. Results: Findings from our literature review indicate that various conditioning activities produce acute PAP effects in subelite and particularly elite athletes. More specifically, conditioning activities that are characterised by multiple sets, moderate to high intensities (60 - 84 % of the one repetition maximum), and rest intervals of 7 - 10 min. following the conditioning activity have the potential to induce short-term improvements in muscle force output and sports performance. Conclusion: It is recommended that subelite and particularly elite athletes from strength, power, and speed disciplines apply specifically tailored conditioning activities during the acute preparation process for competition to induce performance enhancing PAP effects.

However, there is a void in the literature regarding muscle activation levels during the performance of these exercises. Thus, the purpose of this study was to investigate differences in muscle activation during therapeutic climbing exercises depending on the degree of task difficulty. Participants/Material and Methods: A sample of 10 healthy subjects (sex: 4 females, 6 males; age: 27 +/- 3 years; climbing experience: 5 +/- 3 years) performed three shoulder girdle (i.e., wide shoulder pull, narrow shoulder pull, shoulder row) and two leg extensor (i.e., ascending frontal, ascending sidewards) exercises. Electromyographic (EMG) data were recorded on the right side for eleven muscles and then normalised using the maximum voluntary contractions for each muscle. Results: With increasing task difficulty, muscle activity in all but one muscle (i.e., m. trapezius ascendens) increased significantly for the three shoulder girdle exercises. For the two leg extensor exercises, an increase in task difficulty produced a tendency towards yet not significantly higher muscle activity. Conclusion: Shoulder row was the most effective therapeutic climbing exercise in the ability to activate muscles while showing the highest EMG signals. The absence of significant differences in muscle activity between the two leg extensor exercises indicates their equivalent use for muscle activation during therapy.

Association of balance, strength, and power measures in young adults. J Strength Cond Res 27(3): 582-589, 2013-The purpose of this study was to investigate the relationship between variables of static/dynamic balance, isometric strength, and power. Twenty-seven young healthy adults (mean age: 23 6 4 years) performed measurements of static (unperturbed)/dynamic (perturbed) balance, isometric strength (i.e., maximal isometric torque [MIT]; rate of torque development [RTD] of the plantar flexor), and power (i.e., countermovement jump [CMJ] height and power). No significant associations were found between variables of static and dynamic balance (r = -0.090 to + 0.329, p > 0.05) and between measures of static/dynamic balance and isometric strength (r = +0.041 to +0.387, p > 0.05) and static/dynamic balance and power (r = -0.076 to + 0.218, p > 0.05). Significant positive correlations (r) were detected between variables of power and isometric strength ranging from +0.458 to +0.689 (p, 0.05). Furthermore, simple regression analyses revealed that a 10% increase in mean CMJ height (4.1 cm) was associated with 22.9 N.m and 128.4 N.m.s(-1) better MIT and RTD, respectively. The nonsignificant correlation between static and dynamic balance measures and between static/dynamic balance, isometric strength, and power variables implies that these capacities may be independent of each other and may have to be tested and trained complementarily.

Prominent intrinsic fall-risk factors are age-related decreases in balance and strength / power performance as well as cognitive decline. Additional studies are needed to develop specifically tailored exercise programs for older adults that can easily be implemented into clinical practice. Thus, the objective of the present trial is to assess the effects of a fall prevention program that was developed by an interdisciplinary expert panel on measures of balance, strength / power, body composition, cognition, psychosocial well-being, and falls self-efficacy in healthy older adults. Additionally, the time-related effects of detraining are tested. Methods/Design: Healthy old people (n = 54) between the age of 65 to 80 years will participate in this trial. The testing protocol comprises tests for the assessment of static / dynamic steady-state balance (i.e., Sharpened Romberg Test, instrumented gait analysis), proactive balance (i.e., Functional Reach Test; Timed Up and Go Test), reactive balance (i.e., perturbation test during bipedal stance; Push and Release Test), strength (i.e., hand grip strength test; Chair Stand Test), and power (i.e., Stair Climb Power Test; countermovement jump). Further, body composition will be analysed using a bioelectrical impedance analysis system. In addition, questionnaires for the assessment of psychosocial (i.e., World Health Organisation Quality of Life Assessment-Bref), cognitive (i.e., Mini Mental State Examination), and fall risk determinants (i.e., Fall Efficacy Scale -International) will be included in the study protocol. Participants will be randomized into two intervention groups or the control / waiting group. After baseline measures, participants in the intervention groups will conduct a 12-week balance and strength / power exercise intervention 3 times per week, with each training session lasting 30 min. (actual training time). One intervention group will complete an extensive supervised training program, while the other intervention group will complete a short version (` 3 times 3') that is home-based and controlled by weekly phone calls. Post-tests will be conducted right after the intervention period. Additionally, detraining effects will be measured 12 weeks after program cessation. The control group / waiting group will not participate in any specific intervention during the experimental period, but will receive the extensive supervised program after the experimental period. Discussion: It is expected that particularly the supervised combination of balance and strength / power training will improve performance in variables of balance, strength / power, body composition, cognitive function, psychosocial well-being, and falls self-efficacy of older adults. In addition, information regarding fall risk assessment, dose-response-relations, detraining effects, and supervision of training will be provided. Further, training-induced health-relevant changes, such as improved performance in activities of daily living, cognitive function, and quality of life, as well as a reduced risk for falls may help to lower costs in the health care system. Finally, practitioners, therapists, and instructors will be provided with a scientifically evaluated feasible, safe, and easy-to-administer exercise program for fall prevention.

Modeled from a principal-agent perspective, the managing referee boards can be seen as the principal. They aim at facilitating a fair competition which is in accordance with the existing rules and regulations. In doing so, the referees are assigned as impartial agents on the pitch. The coaches take over a non-legitimate principal-like role trying to influence the referees even though they do not have the formal right to do so. Separate questionnaires were set up for referees and coaches. The coach questionnaire aimed at identifying the extent and the forms of influencing attempts by coaches. The referee questionnaire tried to elaborate on the questions if referees take notice of possible influencing attempts and how they react accordingly. The results were put into relation with official match data in order to identify significant influences on personal sanctions (yellow cards, second yellow cards, red cards) and the match result. It is found that there is a slight effect on the referee’s decisions. However, this effect is rather disadvantageous for the influencing coach and there is no evidence for an impact on the match result itself. N2 - Die Arbeit untersucht die Frage, ob Trainer im nicht-professionellen Fußball Schiedsrichterentscheidungen beeinflussen können. Aufbauend auf einer Prinzipal-Agent Perspektive nehmen die Schiedsrichterausschüsse die Rolle des Prinzipals ein. Sie zielen darauf ab, einen fairen Wettkampf zu organisieren, der in Übereinstimmung mit dem geltenden Regelwerk durchgeführt wird. Um dies zu erreichen, werden die Schiedsrichter als unparteiische Agenten auf dem Spielfeld eingesetzt. Die Trainer nehmen in dieser Konstellation eine illegitime, prinzipal-ähnliche Rolle ein und versuchen, den Schiedsrichter zu ihren Gunsten zu beeinflussen. Dies geschieht, ohne dass die Trainer ein entsprechendes Recht dazu hätten. Sowohl für die Trainer als auch für die Schiedsrichter wurde ein Fragebogen entworfen. Der erstgenannte zielt darauf ab, das Ausmaß und die Form von Beeinflussungsversuchen zu erheben. Der Schiedsrichter-Fragebogen hingegen erörtert die Fragen, ob die Unparteiischen mögliche Beeinflussungsversuche durch die Trainer wahrnehmen und wie sie gegebenenfalls darauf reagieren. Die Ergebnisse wurden mit offiziellen Spieldaten in Verbindung gebracht um potentielle Einflüsse auf Spiele (persönliche Strafen sowie das Endergebnis) zu identifizieren. Es wurde herausgefunden, dass es einen leichten Effekt auf Schiedsrichterentscheidungen gibt. Dieser ist zumeist jedoch nachteilig für den jeweiligen Trainer und es gibt kein Indiz für einen Einfluss auf das Endergebnis.

These spatial-temporal associations have an impact on our sensorimotor system: thinking about one's past and future leads to subtle body sways in the sagittal dimension of space (Miles, Nind, & Macrae, 2010). In this study we investigated whether mental time travel leads to sensorimotor correlates in the horizontal dimension of space. Participants were asked to mentally displace themselves into the past or future while measuring their spontaneous eye movements on a blank screen. Eye gaze was directed more rightward and upward when thinking about the future than when thinking about the past. Our results provide further insight into the spatial nature of temporal thoughts, and show that not only body, but also eye movements follow a (diagonal) "time line" during mental time travel.

F1 and F2 trajectories were fitted with parametric curves using the discrete cosine transform (DCT) and the zeroth DCT coefficient represented formant trajectory means and the first DCT coefficient represented the magnitude and direction of formant trajectory change to characterize vowel inherent spectral change (VISC). Cross-dialectal comparisons involving these measures revealed significant differences for the phonologically back monophthongs /D, , , u:/ and also /3z:/ and the diphthongs /eI, e, aI, I/. Most cross-dialectal differences are in zeroth DCT coefficients, suggesting formant trajectory means tend to characterize such differences, while first DCT coefficient differences were more numerous for diphthongs. With respect to VISC, the most striking differences are that /u:/is considerably more diphthongized in the Northern dialect and that the F2 trajectory of /e/proceeds in opposite directions in the two dialects. Cross-dialectal differences were found to be largely unaffected by the consonantal context in which the vowels were produced. The implications of the results are discussed in relation to VISC, consonantal context effects and speech perception. (c) 2014 Acoustical Society of America.

The aim was to identify relevant parameters in order to objectively assess the in-patient rehabilitation outcome. Methods: From February 2009 to June 2010 1253 patients (70.9 +/- 7.0 years, 78.1% men) at 12 rehabilitation clinics were enrolled. Items concerning sociodemographic data, the impairment group (surgery, conservative/interventional treatment), cardiovascular risk factors, structural and functional parameters and subjective health were tested in respect of their measurability, sensitivity to change and their propensity to be influenced by rehabilitation. Results: The majority of patients (61.1%) were referred for rehabilitation after cardiac surgery, 38.9% after conservative or interventional treatment for an acute coronary syndrome. Functionally relevant comorbidities were seen in 49.2% (diabetes mellitus, stroke, peripheral artery disease, chronic obstructive lung disease). In three key areas 13 parameters were identified as being sensitive to change and subject to modification by rehabilitation: cardiovascular risk factors (blood pressure, low-density lipoprotein cholesterol, triglycerides), exercise capacity (resting heart rate, maximal exercise capacity, maximal walking distance, heart failure, angina pectoris) and subjective health (IRES-24 (indicators of rehabilitation status): pain, somatic health, psychological well-being and depression as well as anxiety on the Hospital Anxiety and Depression Scale). Conclusion: The outcome of in-patient rehabilitation in elderly patients can be comprehensively assessed by the identification of appropriate key areas, that is, cardiovascular risk factors, exercise capacity and subjective health. This may well serve as a benchmark for internal and external quality management.

The aim of a cardiac rehabilitation is to improve overall physical health, psychological well-being, physical function, the ability to participate in social life and help patients to change their habits. Regarding the heterogeneity of these aims measuring of the effect of cardiac rehabilitation is still a challenge. This study recommends a concept to assess the effects of cardiac rehabilitation regarding the individual change of relevant quality indicators. Methods: With EVA-Reha; cardiac rehabilitation the Medical Advisory Service of Statutory Health Insurance Funds in Rhineland-Palatinate, Alzey (MDK Rheinland-Pfalz) developed a software to collect data set including sociodemographic and diagnostic data and also the results of specific assessments. The project was funded by the Techniker Krankenkasse, Hamburg, and supported by participating rehabilitation centers. From 01. July 2010 to 30. June 2011 1309 patients (age 71.5 years, 76.1% men) from 13 rehabilitation centers were consecutively enrolled. 13 quality indicators in 3 scales were developed for evaluation of cardiac rehabilitation: 1) cardiovascular risk factors (blood pressure, LDL cholesterol, triglycerides), 2) exercise capacity (resting heart rate, maximal exercise capacity, maximal walking distance, heart failure [NYHA classification], and angina pectoris [CCS classification]) and 3) subjective health (IRES-24: pain, somatic health, psychological wellbeing and depression as well as anxiety on the HADS). The study was prospective; data of patients were assessed at entry and discharge of rehabilitation. To measure the success of rehabilitation each parameter was graded in severity classes at entry and discharge. For each of the 13 quality indicators changes of severity class were rated in a rating matrix. For indicators without a requirement for medical care neither at entry nor at discharge no rating was performed. Results: The grading into severity classes as well as the minimal important differences were given for the 13 quality indicators. The result of rehabilitation can be demonstrated in suitable form by means of rating of the 13 quality indicators according to a clinical population. The rating model differs well between clinically changed and unchanged patients for the quality indicators. Conclusion: The result of cardiac rehabilitation can be assessed with 13 quality indicators measured at entry and discharge of the rehabilitation program. If a change into a more favorable category at the end of rehabilitation could be achieved it was counted as a success. The 13 quality indicators can be used to assess the individual result as well as the result of a population - e.g. all patients of a clinic in a specific time period. In addition, the assessment and rating of relevant quality indicators can be used for comparisons of rehabilitation centers.

No predictors for travel activity and for travel-associated haemorrhage or thromboembolic complications of patients on OAT are known. Methods: A standardised questionnaire was sent to 2500 patients on long-term OAT in Austria, Switzerland and Germany. 997 questionnaires were received (responder rate 39.9%). Ordinal or logistic regression models with travel activity before and after onset of OAT or travel-associated haemorrhages and thromboembolic complications as outcome measures were applied. Results: 43.4% changed travel habits since onset of OAT with 24.9% and 18.5% reporting decreased or increased travel activity, respectively. Long-distance worldwide before OAT or having suffered from thromboembolic complications was associated with reduced travel activity. Increased travel activity was associated with more intensive travel experience, increased duration of OAT, higher education, or performing patient self-management (PSM). Travel-associated haemorrhages or thromboennbolic complications were reported by 6.5% and 0.9% of the patients, respectively. Former thromboennbolic complications, former bleedings and PSM were significant predictors of travel-associated complications. Conclusions: OAT also increases travel intensity. Specific medical advice prior travelling to prevent complications should be given especially to patients with former bleedings or thromboennbolic complications and to those performing PSM.

CKD carries prognostic relevance. We aimed to describe patient characteristics, risk factor management and control status of patients in cardiac rehabilitation (CR), differentiated by presence or absence of CKD. Design and methods: Data from 92,071 inpatients with adequate information to calculate glomerular filtration rate (GFR) based on the Cockcroft-Gault formula were analyzed at the beginning and the end of a 3-week CR stay. CKD was defined as estimated GFR <60 ml/min/1.73 m(2). Results: Compared with non-CKD patients, CKD patients were significantly older (72.0 versus 58.0 years) and more often had diabetes mellitus, arterial hypertension, and atherothrombotic manifestations (previous stroke, peripheral arterial disease), but fewer were current or previous smokers had a CHD family history. Exercise capacity was much lower in CKD (59 vs. 92Watts). Fewer patients with CKD were treated with percutaneous coronary intervention (PCI), but more had coronary artery bypass graft (CABG) surgery. Patients with CKD compared with non-CKD less frequently received statins, acetylsalicylic acid (ASA), clopidogrel, beta blockers, and angiotensin converting enzyme (ACE) inhibitors, and more frequently received angiotensin receptor blockers, insulin and oral anticoagulants. In CKD, mean low density lipoprotein cholesterol (LDL-C), total cholesterol, and high density lipoprotein cholesterol (HDL-C) were slightly higher at baseline, while triglycerides were substantially lower. This lipid pattern did not change at the discharge visit, but overall control rates for all described parameters (with the exception of HDL-C) were improved substantially. At discharge, systolic blood pressure (BP) was higher in CKD (124 versus 121 mmHg) and diastolic BP was lower (72 versus 74 mmHg). At discharge, 68.7% of CKD versus 71.9% of non-CKD patients had LDL-C <100 mg/dl. Physical fitness on exercise testing improved substantially in both groups. When the Modification of Diet in Renal Disease (MDRD) formula was used for CKD classification, there was no clinically relevant change in these results. Conclusion: Within a short period of 3-4 weeks, CR led to substantial improvements in key risk factors such as lipid profile, blood pressure, and physical fitness for all patients, even if CKD was present.

Thirty-four children including 8 children with a family risk for developmental language impairment were tested on the discrimination of trochaic and iambic disyllabic sequences when they were 4 months old. At 5 years of age, standardized measures on language performance (SETK3-5) and nonverbal intelligence (SON-R) were obtained. Overall, evidence of discrimination of the rhythmic patterns was found only for children without a family risk. The performance in early rhythmic discrimination correlated with the later outcomes in SETK3-5 subtests on sentence comprehension and morphological skills, but not with subtests related to memory performance nor with nonverbal intelligence. Our results suggest that indicators of language development can be discovered as early as 4 months of age, and seem to correlate with later outcomes in rather specific language skills.

A1 - Nuerk, Hans-Christoph T1 - Aspects of situated cognition in embodied numerosity: the case of finger counting JF - Cognitive processing : international quarterly of cognitive science N2 - Numerical cognitions such as spatial-numerical associations have been observed to be influenced by grounded, embodied and situated factors. For the case of finger counting, grounded and embodied influences have been reported. However, situated influences, e.g., that reported counting habits change with perception and action within a given situation, have not been systematically examined. To pursue the issue of situatedness of reported finger-counting habits, 458 participants were tested in three separate groups: (1) spontaneous condition: counting with both hands available, (2) perceptual condition: counting with horizontal (left-to-right) perceptual arrangement of fingers (3) perceptual and proprioceptive condition: counting with horizontal (left-to-right) perceptual arrangement of fingers and with busy dominant hand. Report of typical counting habits differed strongly between the three conditions. 28 % reported to start counting with the left hand in the spontaneous counting condition (1), 54 % in the perceptual condition (2) and 62 % in the perceptual and proprioceptive condition (3). Additionally, all participants in the spontaneous counting group showed a symmetry-based counting pattern (with the thumb as number 6), while in the two other groups, a considerable number of participants exhibited a spatially continuous counting pattern (with the pinkie as number 6). Taken together, the study shows that reported finger-counting habits depend on the perceptual and proprioceptive situation and thus are strongly influenced by situated cognition. We suggest that this account reconciles apparently contradictory previous findings of different counting preferences regarding the starting hand in different examination situations.

(GTH) N2 - A recently developed multiparameter computer-aided expert system (TheMa) for guiding anticoagulation with phenprocoumon (PPC) was validated by a prospective investigation in 22 patients. The PPC-INR-response curve resulting from physician guided dosage was compared to INR values calculated by "twin calculation" from TheMa recommended dosage. Additionally, TheMa was used to predict the optimal time to perform surgery or invasive procedures after interruption of anticogulation therapy. Results: Comparison of physician and TheMa guided anticoagulation showed almost identical accuracy by three quantitative measures: Polygon integration method (area around INR target) 616.17 vs. 607.86, INR hits in the target range 166 vs. 161, and TTR (time in therapeutic range) 63.91 vs. 62.40 %. After discontinuation of anticoagulation therapy, calculating the INR phase-out curve with TheMa INR prognosis of 1.8 was possible with a standard deviation of 0.50 +/- 0.59 days. Conclusion: Guiding anticoagulation with TheMa was as accurate as Physician guided therapy. After interruption of anticoagulant therapy, TheMa may be used for calculating the optimal time performing operations or initiating bridging therapy.

Much has been learned about the spatial selection of fixation locations, while the principles governing the temporal control (fixation durations) are less clear. Here, we review current theories for the control of fixation durations in tasks like visual search, scanning, scene perception, and reading and propose a new model for the control of fixation durations. We distinguish two local principles from one global principle of control. First, an autonomous saccade timer initiates saccades after random time intervals (local-I). Second, foveal inhibition permits immediate prolongation of fixation durations by ongoing processing (local-II). Third, saccade timing is adaptive, so that the mean timer value depends on task requirements and fixation history (Global). We demonstrate by numerical simulations that our model qualitatively reproduces patterns of mean fixation durations and fixation duration distributions observed in typical experiments. When combined with assumptions of saccade target selection and oculomotor control, the model accounts for both temporal and spatial aspects of eye movement control in two versions of a visual search task. We conclude that the model provides a promising framework for the control of fixation durations in saccadic tasks.
