Проведен анализ пространственной семантики различных категорий русских существительных, входящих в психолингви-стическую базуданных; особое внимание уделяется абстрактным концептам. Выявлены различия пространственной семантики наименований физических ощущений и действий, эмоций, ментальных процессов. Полученны ерезультаты обсуждаются с точки зрения отдельных подходов в рамках теории воплощенного познания – теории концептуальной метафоры, теории слов как социальных инструментов (WAT, Words As social Tools), нейросемантики.
In an eye-tracking study we tested the hypothesis that comprehension is facilitated by a match between the order of the verb and its arguments in a sentence and the order of the actual sensorimotor interaction with these objects (for example, in the phrase put the bag into the box, the order of the arguments corresponds to the order of motor actions: take the bag, put it into the box) could facilitate comprehension of such constructions. We tested 40 native Russian speakers in a visual world sentence-picture matching task. In prepositional constructions, there was no difference between conditions that matched or mismatched sensorimotor stereotypes, whereas in instrumental constructions, sensorimotor stereotypes facilitated comprehension.
Zur Rolle des Pronomen to/eto in spezifizierenden Kopulaktionstrukturen im polnischen und russischen
(2001)
The article presents first results of a pilot study on the syntactic changes in Polish as a language contact in Germany. On the base of the experimental data tests the study examines the syntactic changes in Polish of two diaspora-generations: the so called forgetters and the incomplete learners. The article focuses on the questions: how the situation of languages in contact influences the syntactic changes in the heritage language (Polish) and which status have those syntactic transferences. Other linguistic and sociolinguistic factors, capable to cause the language change in the situation of language contact, are also discussed in the article.
Der W-Fragen-Erwerb stellt einen Teilbereich der kindlichen Syntaxentwicklung dar, die sich maßgeblich innerhalb der ersten drei Lebensjahre eines Kindes vollzieht. Eine wesentliche Rolle spielen dabei zwei Bewegungsoperationen, die sich auf die Position des Interrogativpronomens an die erste Stelle der W-Frage sowie die Position des Verbs an die zweite Stelle beziehen. In drei Studien wurde einerseits untersucht, ob deutschsprachige Kinder, die noch keine W-Fragen produzieren können, in der Lage sind, grammatische von ungrammatischen W-Fragen zu unterscheiden und andererseits, welche Leistungen sprachunauffällige und sprachauffällige deutschsprachige Kinder beim Verstehen und Korrigieren unterschiedlich komplexer W-Fragen (positive und negative W-Fragen) zeigen. Die Ergebnisse deuten auf ein frühes syntaktisches Wissen über W-Fragen im Spracherwerb hin und stützen damit die Annahme einer Kontinuität der kindlichen Grammatik zur Standardsprache. Auch scheinen sprachauffällige Kinder sich beim Erwerb von W-Fragen nicht qualitativ von sprachgesunden Kindern zu unterscheiden, sondern W-Fragen lediglich später korrekt umzusetzen. In beiden Populationen konnte ein syntaktischer Ökonomieeffekt beobachtet werden, der für eine spätere Umsetzung der Verbbewegung im Vergleich zur Bewegung des W-Elementes spricht.
In the present study, we investigated younger and older Persian preschoolers' response tendency and accuracy toward yes/no questions about a coloring activity. Overall, 107 three- to four-year-olds and five- to six-year-old children were asked positive and negative yes/no questions about a picture coloring activity. The questions focused on three question contents namely, actions, environment and person. As for children's response tendency, they showed a compliance tendency. That is, they provided yes and no responses to positively and negatively formed questions respectively. Children especially younger ones were more compliant toward positive questions and their tendency decreased by age. In addition, the results revealed children's highest rate of compliance tendency toward environment inquiries. Concerning response accuracy, the effects of age and question content were significant. Specifically, older children provided more accurate responses than their younger counterparts, especially to yes/no questions asked about the actions performed during the activity. The findings suggest that depending on the format and the content of yes/no questions younger and older children's response accuracy and tendency differ.

Wortartige Zwischenfälle
(2004)
There is a wealth of evidence showing that increasing the distance between an argument and its head leads to more processing effort, namely, locality effects: these are usually associated with constraints in working memory (DLT: Gibson, 2000: activation-based model: Lewis and Vasishth, 2005). In SOV languages, however, the opposite effect has been found: antilocality (see discussion in Levy et al., 2013). Antilocality effects can be explained by the expectation based approach as proposed by Levy (2008) or by the activation-based model of sentence processing as proposed by Lewis and Vasishth (2005). We report an eye-tracking and a self-paced reading study with sentences in Spanish together with measures of individual differences to examine the distinction between expectation- and memory based accounts, and within memory-based accounts the further distinction between DLT and the activation-based model. The experiments show that (i) antilocality effects as predicted by the expectation account appear only for high-capacity readers; (ii) increasing dependency length by interposing material that modifies the head of the dependency (the verb) produces stronger facilitation than increasing dependency length with material that does not modify the head; this is in agreement with the activation-based model but not with the expectation account; and (iii) a possible outcome of memory load on low-capacity readers is the increase in regressive saccades (locality effects as predicted by memory-based accounts) or, surprisingly, a speedup in the self-paced reading task; the latter consistent with good-enough parsing (Ferreira et al., 2002). In sum, the study suggests that individual differences in working memory capacity play a role in dependency resolution, and that some of the aspects of dependency resolution can be best explained with the activation-based model together with a prediction component.

Words as social tools
(2019)
There is evidence that infants start extracting words from fluent speech around 7.5 months of age (e.g., Jusczyk & Aslin, 1995) and that they use at least two mechanisms to segment words forms from fluent speech: prosodic information (e.g., Jusczyk, Cutler & Redanz, 1993) and statistical information (e.g., Saffran, Aslin & Newport, 1996). However, how these two mechanisms interact and whether they change during development is still not fully understood.
The main aim of the present work is to understand in what way different cues to word segmentation are exploited by infants when learning the language in their environment, as well as to explore whether this ability is related to later language skills. In Chapter 3 we pursued to determine the reliability of the method used in most of the experiments in the present thesis (the Headturn Preference Procedure), as well as to examine correlations and individual differences between infants’ performance and later language outcomes. In Chapter 4 we investigated how German-speaking adults weigh statistical and prosodic information for word segmentation. We familiarized adults with an auditory string in which statistical and prosodic information indicated different word boundaries and obtained both behavioral and pupillometry responses. Then, we conducted further experiments to understand in what way different cues to word segmentation are exploited by 9-month-old German-learning infants (Chapter 5) and by 6-month-old German-learning infants (Chapter 6). In addition, we conducted follow-up questionnaires with the infants and obtained language outcomes at later stages of development.
Our findings from this thesis revealed that (1) German-speaking adults show a strong weight of prosodic cues, at least for the materials used in this study and that (2) German-learning infants weight these two kind of cues differently depending on age and/or language experience. We observed that, unlike English-learning infants, 6-month-old infants relied more strongly on prosodic cues. Nine-month-olds do not show any preference for either of the cues in the word segmentation task. From the present results it remains unclear whether the ability to use prosodic cues to word segmentation relates to later language vocabulary. We speculate that prosody provides infants with their first window into the specific acoustic regularities in the signal, which enables them to master the specific stress pattern of German rapidly. Our findings are a step forwards in the understanding of an early impact of the native prosody compared to statistical learning in early word segmentation.
This article investigates the word order preferences of Tagalog-speaking adults and five- and seven-year-old children. The participants were asked to complete sentences to describe pictures depicting actions between two animate entities. Adults preferred agent-initial constructions in the patient voice but not in the agent voice, while the children produced mainly agent-initial constructions regardless of voice. This agent-initial preference, despite the lack of a close link between the agent and the subject in Tagalog, shows that this word order preference is not merely syntactically-driven (subject-initial preference). Additionally, the children’s agent-initial preference in the agent voice, contrary to the adults’ lack of preference, shows that children do not respect the subject-last principle of ordering Tagalog full noun phrases. These results suggest that language-specific optional features like a subject-last principle take longer to be acquired.
We report two corpus analyses to examine the impact of animacy, definiteness, givenness and type of referring expression on the ordering of double objects in the spontaneous speech of German-speaking two- to four-year-old children and the child-directed speech of their mothers. The first corpus analysis revealed that definiteness, givenness and type of referring expression influenced word order variation in child language and child-directed speech when the type of referring expression distinguished between pronouns and lexical noun phrases. These results correspond to previous child language studies in English (e.g., de Marneffe et al. 2012). Extending the scope of previous studies, our second corpus analysis examined the role of different pronoun types on word order. It revealed that word order in child language and child-directed speech was predictable from the types of pronouns used. Different types of pronouns were associated with different sentence positions but also showed a strong correlation to givenness and definiteness. Yet, the distinction between pronoun types diminished the effects of givenness so that givenness had an independent impact on word order only in child-directed speech but not in child language. Our results support a multi-factorial approach to word order in German. Moreover, they underline the strong impact of the type of referring expression on word order and suggest that it plays a crucial role in the acquisition of the factors influencing word order variation.
Georgian is famous for its word order flexibility: all permutations of constituent order are possible and the choice among them is primarily determined by information structure. In this paper, we show that word order is not the only means to encode information structure in this language, but it is used in combination with sentence prosody. After a preliminary description of the use of prosodic phrasing and intonation for this purpose, we address the question of the interrelation between these two strategies. Based on experimental evidence, we investigate the interaction of focus with word order and prosody, and we conclude that some aspects of word order variation are pragmatically vacuous and can be accommodated in any context if they are realized with an appropriate prosodic structure, while other word order phenomena are quite restrictive and cannot be overridden through prosodic manipulations.
Electrophysiological research using verbal response paradigms faces the problem of muscle artifacts that occur during speech production or in the period preceding articulation. In this context, this paper has two related aims. The first is to show how the nature of the first phoneme influences the alignment of the ERPs. The second is to further characterize the EEG signal around the onset of articulation, both in temporal and frequency domains. Participants were asked to name aloud pictures of common objects. We applied microstate analyses and time-frequency transformations of ERPs locked to vocal onset to compare the EEG signal between voiced and unvoiced labial plosive word onset consonants. We found a delay of about 40 ms in the set of stable topographic patterns for /b/ relative to /p/ onset words. A similar shift was observed in the power increase of gamma oscillations (30-50 Hz), which had an earlier onset for /p/ trials (similar to 150 ms before vocal onset). This 40-ms shift is consistent with the length of the voiced proportion of the acoustic signal prior to the release of the closure in the vocal responses. These results demonstrate that phonetic features are an important parameter affecting response-locked ERPs, and hence that the onset of the acoustic energy may not be an optimal trigger for synchronizing the EEG activity to the response in vocal paradigms. The indexes explored in this study provide a step forward in the characterization of muscle-related artifacts in electrophysiological studies of speech and language production.
One of the core issues in psycholinguistic research concerns the relationship between word category information and verb-argument structure (e.g. transitivity) information of verbs in the process of sentence parsing. In two experiments (visual versus auditory presentation) using event-related brain potentials (ERPs), we addressed this question by presenting sentences in which the critical word simultaneously realized both a word category and a transitivity violation. ERPs for sentences with both types of violation clustered with the patterns for sentences with a word category violation only, but were different from the patterns elicited by argument structure violations in isolation, since only the latter elicited an N400 ERP component. The finding that an argument structure violation evoked an N400 only if the phrase structure of the respective sentence was correct suggests that a successful integration of the word category information of a verb functionally precedes the application of its argument structure information.

Die vorliegende Arbeit befasst sich mit der wissensbasierten Modellierung von Audio-Signal-Klassifikatoren (ASK) für die Bioakustik. Sie behandelt ein interdisziplinäres Problem, das viele Facetten umfasst. Zu diesen gehören artspezifische bioakustische Fragen, mathematisch-algorithmische Details und Probleme der Repräsentation von Expertenwissen. Es wird eine universelle praktisch anwendbare Methode zur wissensbasierten Modellierung bioakustischer ASK dargestellt und evaluiert. Das Problem der Modellierung von ASK wird dabei durchgängig aus KDD-Perspektive (Knowledge Discovery in Databases) betrachtet. Der grundlegende Ansatz besteht darin, mit Hilfe von modifizierten KDD-Methoden und Data-Mining-Verfahren die Modellierung von ASK wesentlich zu erleichtern. Das etablierte KDD-Paradigma wird mit Hilfe eines detaillierten formalen Modells auf den Bereich der Modellierung von ASK übertragen. Neunzehn elementare KDD-Verfahren bilden die Grundlage eines umfassenden Systems zur wissensbasierten Modellierung von ASK. Methode und Algorithmen werden evaluiert, indem eine sehr umfangreiche Sammlung akustischer Signale des Großen Tümmlers mit ihrer Hilfe untersucht wird. Die Sammlung wurde speziell für diese Arbeit in Eilat (Israel) angefertigt. Insgesamt werden auf Grundlage dieses Audiomaterials vier empirische Einzelstudien durchgeführt: - Auf der Basis von oszillographischen und spektrographischen Darstellungen wird ein phänomenologisches Klassifikationssystem für die vielfältigen Laute des Großen Tümmlers dargestellt. - Mit Hilfe eines Korpus halbsynthetischer Audiodaten werden verschiedene grundlegende Verfahren zur Modellierung und Anwendung von ASK in Hinblick auf ihre Genauigkeit und Robustheit untersucht. - Mit einem speziell entwickelten Clustering-Verfahren werden mehrere Tausend natürliche Pfifflaute des Großen Tümmlers untersucht. Die Ergebnisse werden visualisiert und diskutiert. - Durch maschinelles mustererkennungsbasiertes akustisches Monitoring wird die Emissionsdynamik verschiedener Lauttypen im Verlaufe von vier Wochen untersucht. Etwa 2.5 Millionen Klicklaute werden im Anschluss auf ihre spektralen Charakteristika hin untersucht. Die beschriebene Methode und die dargestellten Algorithmen sind in vielfältiger Hinsicht erweiterbar, ohne dass an ihrer grundlegenden Architektur etwas geändert werden muss. Sie lassen sich leicht in dem gesamten Gebiet der Bioakustik einsetzen. Hiermit besitzen sie auch für angrenzende Disziplinen ein hohes Potential, denn exaktes Wissen über die akustischen Kommunikations- und Sonarsysteme der Tiere wird in der theoretischen Biologie, in den Kognitionswissenschaften, aber auch im praktischen Naturschutz, in Zukunft eine wichtige Rolle spielen.
The Wisconsin Card Sorting Test (WCST) is used to test higher-level executive functions or switching, depending on the measures chosen in a study and its goal. Many measures can be extracted from the WCST, but how to assign them to specific cognitive skills remains unclear. Thus, the current study first aimed at identifying which measures test the same cognitive abilities. Second, we compared the performance of mono- and multilingual children in the identified abilities because there is some evidence that bilingualism can improve executive functions. We tested 66 monolingual and 56 multilingual (i.e., bi- and trilingual) primary school children (M-age = 109 months) in an online version of the classic WCST. A principal component analysis revealed four factors: problem-solving, monitoring, efficient errors, and perseverations. Because the assignment of measures to factors is only partially coherent across the literature, we identified this as one of the sources of task impurity. In the second part, we calculated regression analyses to test for group differences while controlling for intelligence as a predictor for executive functions and for confounding variables such as age, German lexicon size, and socioeconomic status. Intelligence predicted problem solving and perseverations. In the monitoring component (measured by the reaction times preceding a rule switch), multilinguals outperformed monolinguals, thereby supporting the view that bi- or multilingualism can improve processing speed related to monitoring.
Wird Schon Stimmen!
(2018)
The article puts forward a novel analysis of the German modal particle schon as a modal degree operator over propositional content. The proposed analysis offers a uniform perspective on the semantics of modal schon and its aspectual counterpart meaning ‘already’: Both particles are analyzed as denoting a degree operator, expressing a scale-based comparison over relevant alternatives. The alternatives are determined by focus in the case of aspectual schon (Krifka 2000), but are restricted to the polar alternatives p and ¬p in the case of modal schon. Semantically, modal schon introduces a presupposition to the effect that the circumstantial conversational background contains more factual evidence in favor of p than in favor of ¬p, thereby making modal schon the not at-issue counterpart of the overt comparative form eher ‘rather’ (Herburger & Rubinstein 2014). The analysis incorporates basic insights from earlier analyses of modal schon in a novel way, and it also offers new insights as to the underlying workings of modality in natural language as involving propositions rather than possible worlds (Kratzer 1977, 2012).
Wie interpretieren Kinder nur? : Experimentelle Untersuchungen zum Erwerb von Informationsstruktur
(2010)
Im Zentrum der Arbeit steht die Frage, wie sechsjährige monolingual deutsche Kinder Sätze mit der Fokuspartikel nur interpretieren. In 5 Experimenten wurde untersucht, welchen Einfluss die Oberflächenposition der Fokuspartikel auf das Satzverständnis hat und ob die kontextuelle Einbettung der nur-Sätze zu einer zielsprachlichen Interpretation führt. Im Gegensatz zu den Ergebnissen bisheriger Studien (u.a. Crain, et al. 1994; Paterson et al. 2003) zeigen die Daten der Arbeit, dass die getesteten Kinder die präsentierten nur-Sätze zielsprachlich interpretierten, wenn diese in einen adäquaten Kontext eingebettet waren. Es zeigte sich weiterhin, dass die Kinder mehr Fehler bei der Interpretation von Sätzen mit nur vor dem Subjekt (Nur die Maus hat einen Ball.) als mit nur vor dem Objekt (Die Maus hat nur einen Ball.) machten. Entgegen dem syntaktisch basierten Ansatz von Crain et al. (1994) und dem semantisch-pragmatisch basierten Ansatz von Paterson et al. (2003) werden in der Arbeit informationsstrukturelle Eigenschaften bzw. Unterschiede der nur-Sätze für die beobachteten Leistungen verantwortlich gemacht. Der in der Arbeit postulierte Topik-Default Ansatz nimmt an, dass die Kinder das Subjekt eines Satzes immer als Topik analysieren. Dies führt im Fall der Sätze mit nur vor dem Subjekt zu einer falschen informationsstrukturellen Repräsentation des Satzes. Basierend auf den Ergebnissen der Arbeit und dem postulierten Topik-Default Ansatz wird in der Arbeit abschließend ein Erwerbsmodell für das Verstehen von Sätzen mit der Fokuspartikel nur entworfen und diskutiert.
The phenomenon of forced fixations suggests that readers sometimes fixate a word (due to oculomotor constraints) even though they intended to skip it (due to parafoveal cognitive-linguistic processing). We investigate whether this leads readers to look directly at a word but not pay attention to it. We used a gaze-contingent boundary paradigm to dissociate parafoveal and foveal information (e.g., the word phone changed to scarf once the reader's eyes moved to it) and asked questions about the sentence to determine which one the reader encoded. When the word was skipped or fixated only briefly (i.e., up to 100 ms) readers were more likely to report reading the parafoveal than the fixated word, suggesting that there are cases in which readers look directly at a word but their minds ignore it, leading to the illusion of reading something they did not fixate.
What’s Symmetrical?

This chapter investigates teacher management of learner turns in an American second-grade classroom during a read-aloud activity. A read-aloud is a whole-group instructional activity which involves a teacher read-ing aloud a book to a cohort of students as they listen (Tainio & Slotte, 2017). Using ethnomethodological conversation analysis (EMCA) and drawing on the concepts of alignment and affi liation (Steensig, 2012; Stivers, 2008; Stivers et al., 2011), we investigate how embodied practices such as gaze, facial expressions, body positioning and gestures in addition to verbal practices are used by the teacher separately and together to respond to learner turns in ways that keep the learners aff ectively engaged and, at the same time, ensure the orderly progression of the lesson. Our analysis shows that teacher cooperative management of learners’ turns involves: (1) orient-ing to them as affi liative tokens in order to neutralize their disaligning force while still treating learners as cooperative participants in the activity; and (2) managing turns not only according to their sequential positions and the actions they project but, just as importantly, to the larger instructional proj-ect being accomplished. The study contributes to the re-specifi cation of the everyday grounds of teaching in order to broaden understandings of the specialized nature of such work (Macbeth, 2014).
Morphological systems are constrained in how they interact with each other. One case that has been widely studied in the psycholinguistic literature is the avoidance of plurals inside compounds (e.g. *rats eater vs. rat eater) in English and other languages, the so-called plurals-in-compounds effect. Several previous studies have shown that both adult and child speakers are sensitive to this contrast, but the question of whether semantic, morphological, or surface-form constraints are responsible for the plurals-in-compounds effect remains controversial. The present study provides new empirical evidence from adult and child English to resolve this controversy. Graded linguistic judgments were obtained from 96 children (age range: 7;06 to 12;08) and 32 adults. In the task, participants were asked to rate compounds containing different kinds of singular or plural modifiers. The results indicated that both children and adults disliked regular plurals inside compounds, whereas irregular plurals were rated as marginal and singulars as fully acceptable. Furthermore, acceptability ratings were found not to be affected by the phonological surface form of a compound-internal modifier. We conclude that semantic and morphological (rather than surface-form) constraints are responsible for the plurals-in-compounds effect, in both children and adults.
Which repair strategy does the language system deploy when it gets garden-pathed, and what can regressive eye movements in reading tell us about reanalysis strategies? Several influential eye-tracking studies on syntactic reanalysis (Frazier & Rayner, 1982; Meseguer, Carreiras, & Clifton, 2002; Mitchell, Shen, Green, & Hodgson, 2008) have addressed this question by examining scanpaths, i.e., sequential patterns of eye fixations. However, in the absence of a suitable method for analyzing scanpaths, these studies relied on simplified dependent measures that are arguably ambiguous and hard to interpret. We address the theoretical question of repair strategy by developing a new method that quantifies scanpath similarity. Our method reveals several distinct fixation strategies associated with reanalysis that went undetected in a previously published data set (Meseguer et al., 2002). One prevalent pattern suggests re-parsing of the sentence, a strategy that has been discussed in the literature (Frazier & Rayner, 1982); however, readers differed tremendously in how they orchestrated the various fixation strategies. Our results suggest that the human parsing system non-deterministically adopts different strategies when confronted with the disambiguating material in garden-path sentences.
Background: Comprehension of non-canonical sentences is frequently characterised by chance level performance in people with aphasia (PWA). Chance level performance has been interpreted as guessing, but online data does not support this rendering. It is still not clear whether the incorrect sentence processing is guided by the compensatory strategies that PWA might employ to overcome linguistic difficulties.Aims: We aim to study to what extent people with non-fluent aphasia are aware of their sentence comprehension deficits.Methods & Procedures: This study combined offline and online data to investigate the effect of word order and error-awareness on sentence comprehension in a group of PWA and non-brain damaged (NBD) participants. The offline tasks involved auditory sentence picture-matching immediately followed by a confidence rating (CR). Participants were asked to judge the perceived correctness of their previous answer. Online data consisted of eye-tracking.Outcomes & Results: Replicating previous findings, PWA had significantly worse comprehension of Theme-Agent order compared to Agent-Theme order sentences. Controls showed ceiling level sentence comprehension. CR was a poor predictor of response accuracy in PWA, but moderate-good in NBD. A total of 6.8% of judgements were classified as guessing by PWA. Post hoc gaze data analysis indicated that CR was a predictor of the fixation pattern during the presentation of the linguistic stimuli.Conclusions: Results suggest that PWA were mostly unaware of their sentence comprehension errors and did not consciously employ strategies to compensate for their difficulties.
Eye movement data have proven to be very useful for investigating human sentence processing. Eyetracking research has addressed a wide range of questions, such as recovery mechanisms following garden-pathing, the timing of processes driving comprehension, the role of anticipation and expectation in parsing, the role of semantic, pragmatic, and prosodic information, and so on. However, there are some limitations regarding the inferences that can be made on the basis of eye movements. One relates to the nontrivial interaction between parsing and the eye movement control system which complicates the interpretation of eye movement data. Detailed computational models that integrate parsing with eye movement control theories have the potential to unpack the complexity of eye movement data and can therefore aid in the interpretation of eye movements. Another limitation is the difficulty of capturing spatiotemporal patterns in eye movements using the traditional word-based eyetracking measures. Recent research has demonstrated the relevance of these patterns and has shown how they can be analyzed. In this review, we focus on reading, and present examples demonstrating how eye movement data reveal what events unfold when the parser runs into difficulty, and how the parsing system interacts with eye movement control.

When participants in an experiment have to name pictures while ignoring distractor words superimposed on the picture or presented auditorily (i.e., picture-word interference paradigm), they take more time when the word to be named (or target) and distractor words are from the same semantic category (e.g., cat-dog). This experimental effect is known as the semantic interference effect, and is probably one of the most studied in the language production literature. The functional origin of the effect and the exact conditions in which it occurs are however still debated. Since Lupker (1979) reported the effect in the first response time experiment about 40 years ago, more than 300 similar experiments have been conducted. The semantic interference effect was replicated in many experiments, but several studies also reported the absence of an effect in a subset of experimental conditions. The aim of the present study is to provide a comprehensive theoretical review of the existing evidence to date and several Bayesian meta-analyses and meta-regressions to determine the size of the effect and explore the experimental conditions in which the effect surfaces. The results are discussed in the light of current debates about the functional origin of the semantic interference effect and its implications for our understanding of the language production system.
Two recent studies (Johnson et al., 2005; Perez-Leroux, 2006) found that English- and Spanish-learning children do not show the ability to use verb inflection as a cue to subject number before the age of 5 to 6 years. These findings suggest an asymmetric development as verb inflections are usually correctly produced before this age. In the present study we investigated whether German 3- to 4-year-olds take advantage of the information provided by the verb inflection in sentence comprehension. In a first study, children's looking behavior at two pictures was measured after presentation of a sentence in which the subject number was coded only by the verb inflection. The results from this study suggest that children's looks reflect correct interpretation of the sentences and thus show their ability to make use of verb inflection. In a second experiment, preferential looking was combined with an additional task in which the children had to point to the matching picture. in this case children did not perform above chance level. Our results underline the relevance that specific task demands have on the performance of children in comprehension testing. These have to be accounted for when interpreting findings on production and comprehension asymmetries in language acquisition.

Wernicke's 1903 case pure agraphia : an enigma for classical models of written language processing
(1996)
This study is concerned with repair practices that a teacher and students employ to restore intersubjectivity when faced with interactional problems in a Content and Language Integrated Learning (CLIL) classroom. Adopting a conversation analytic (CA) approach, it examines the interactional treatment of students’ verbal and embodied trouble displays in a video-recorded, teacher-fronted geography lesson held in English at a German high school. At the same time, it explores to what extent the repair practices employed are fitted to this specific interactional context. The analysis shows that students’ verbal trouble displays often result in extensive repair sequences, whereas students’ embodied trouble displays are usually met with teacher self-repair in the transition space. In this way, the latter are resolved much earlier and more quickly. The study further reveals practices like reformulation and translation to be especially useful for repairing interactional problems in classrooms in which a foreign language is used as the medium of instruction. The findings may be of interest for prospective as well as practicing teachers in that they provide relevant insights into how interactional trouble can be successfully managed in (CLIL) classroom interaction.
