How language affects social cognition and emotional competence in typical and atypical development: A systematic review.

BACKGROUND: The ability to understand the mental state of others (social cognition), as well as language, is crucial for children to have good social adaptation. Social cognition (SC) has been shown to be a hierarchical model of three factors (Cognitive, intermediate and affective SC) interrelated with linguistic processes. Children on the autism spectrum and children with developmental language disorder (DLD) or social communication disorder (SCD) manifest language and SC difficulties, albeit in different ways. AIMS: This systematic review aims to find how language and SC interact with each other and identify linguistic and socio-affective profiles in the target population. METHODS: About 1593 articles were systematically reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guide in November 2022, obtaining, through inclusion/exclusion criteria, a total of 38 articles for qualitative assessment. The majority of them were on autism (26) or DLD (14) and to a lesser extent SCD (3). MAIN CONTRIBUTION: Although SC is related to all components of language, SC is strongly related to narrative and morphosyntax and partially related to lexicon. Pragmatics shows a complex relation with SC due to greater sensitivity to other factors such as age or task, and prosody appears to be more related to emotional processes. Besides, autistic, SCD and DLD children showed differences in their language and socio-affective performance. Mainstream DLD children have lower performance in general language, where autistic and SCD children have more linguistic variation and are lower in pragmatic and SC tasks, SCD children being more associated with language production difficulties and autistic children with both receptive and productive language. CONCLUSION: Each language component has a different interaction with SC. Likewise, different linguistic profiles are partially found for each disorder. These results are important for future lines of research focusing on specific components of interaction and socio-emotional processes, as well as for clinical and educational treatment. WHAT THIS PAPER ADDS: What is already known on the subject The hierarchical model of Schurz et al. (2021), divide social cognition into three brain constructs: cognitive social cognition (CSC), affective social cognition (ASC) and intermediate social cognition (ISC). They observe a large relationship between language and ISC, a fact that has been corroborated with some other studies. Studies have also found lower linguistic and socio-affective abilities in children with autism and language and communication disorders compared with children with neurotypical development, and large behavioural and neurocognitive overlaps between these disorders (Durrleman et al., 2019; Löytömäki et al., 2019). What this paper adds to existing knowledge This is the first review that relates all linguistic components (narrative, lexicon, morphosyntax, pragmatic and prosody) with the three constructs of social cognition (Cognitive, intermediate and affective). Moreover, it is the first review that studies the socio-linguistic factors comparing autism, developmental language disorder and social communication disorder with each other and with neurotypical development in children aged from 4 to 9 years. What are the potential or actual clinical implications of this work? Understanding how language and social cognition interact with each other in autism spectrum disorder, developmental language disorder and social communication disorder allows us to trace socio-linguistic profiles for each of the studied disorders, understand better children with these difficulties, and, with this, find specific potential intervention points to improve and prevent these difficulties.

Grammatical correction and morphological productivity tasks as potential identifiers of developmental language disorder in Spanish-Catalan bilingual children: a pilot study.

A critical problem for Catalan-Spanish bilinguals is the lack of assessment tools to conduct valid and accurate oral language evaluations. The purpose of this preliminary study was to provide pilot data for a new potential assessment tool in Catalan. We examined the possibility that two novel tasks, a grammatical correction (GramCorr) and morphological productivity (MP; nonword and word subtasks), could differentiate between Catalan-speaking children with and without developmental language disorder (DLD) with good diagnostic accuracy. Twenty-seven school-aged children with DLD (Mage = 9;1 years) and twenty-seven age/sex-matched typically developing (TD) children (Mage = 9;0 years) participated in the study. Group differences and diagnostic accuracy analyses (sensitivity and specificity and likelihood ratios) were conducted. Results showed that the overall accuracy of children with DLD was significantly poorer than that of the TD controls in the two tasks. The preliminary diagnostic accuracy results suggested that the overall test (GramCorr+MP) could be useful in identifying children with DLD (cut-off point 62.1%; sensitivity (.929)/specificity (.893); +LH (8.67)/-LH (0.80). Moreover, the overall MP task (nonword + word subtasks; cut-off point 60%; sensitivity (.897)/specificity (.931), +LH (13.00)/-LH (0.111)) appears to provide adequate information to help in detecting DLD. The nature of both tasks, their usefulness for practitioners and future steps in the design of valid tools for the identification of Catalan speaking children with DLD are discussed.

Statistical word learning in Catalan-Spanish and English-speaking children with and without developmental language disorder.

BACKGROUND: A growing body of work shows that children with developmental language disorder (DLD) perform poorly on statistical word learning (SWL) tasks, consistent with the predictions of the Procedural Deficit Hypothesis that predicts that procedural memory is impaired in DLD. To date, however, SWL performance has not been compared across linguistically heterogeneous populations of children with DLD. AIMS: To compare SWL performance in a group of age, sex and non-verbal IQ-matched Catalan-Spanish and English-speaking children with and without DLD. METHODS & PROCEDURES: Two cohorts of children: (1) 35 Catalan-Spanish-speaking children with DLD (Mage = 8;7 years) and 35 age/sex-matched typical developing (TD) children (Mage = 8;9 years), and (2) 24 English-speaking children with DLD (Mage = 9;1 years) and 19 age/sex matched TD controls (Mage = 8;9 years) completed the tone version of a SWL task from Evans et al. (2009). Children listened to a tone language in which transitional probabilities within tone words were higher than those between words. OUTCOMES & RESULTS: For both Catalan-Spanish and English cohorts, overall performance for the children with DLD was poorer than that of the TD controls regardless of the child's native language. Item analysis revealed that children with DLD had difficulty tracking statistical information and using transitional probability to discover tone word boundaries within the input. For both the Catalan-Spanish and English-speaking children, SWL accounted for a significant amount of unique variance in Receptive and Expressive vocabulary. Likelihood ratio analysis revealed that for both Catalan-Spanish and English cohorts, children having performance ≤ 45% on the SWL task had an extremely high degree of likelihood of having DLD. The analysis also revealed that for the Catalan-Spanish and English-speaking children, scores of ≥ 75% and ≥ 70%, respectively, were highly likelihood to be children with normal language abilities. CONCLUSIONS & IMPLICATIONS: The findings add to a pattern suggesting that SWL is a mechanism that children rely on to acquire vocabulary. The results also suggest that SWL deficits, in particular when combined with other measures, may be a reliable diagnostic indicator for children with DLD regardless of the child's native language, and whether or not the child is bilingual or monolingual. WHAT THIS PAPER ADDS: What is already known on the subject Although there is some disagreement, a small but growing body of work suggests that deficits in procedural memory, as measured either by motor sequencing (Serial Reaction Time-SRT) or SWL tasks, may be part of the deficit profile of children with DLD. To date, studies have not examined SWL across linguistically heterogeneous populations of children with DLD to determine if it is a unique clinical marker of the disorder. What this paper adds to existing knowledge The results show that children with DLD, regardless of their native language, or whether the child is bi- or monolingual, have difficulties on SWL tasks, and that these deficits are linked to severity of the language disorder. Taken together, these results indicate that procedural memory deficits may be a core feature of DLD. This suggests that statistical-learning tasks using tone stimuli can also advance our understanding of statistical-learning abilities in children with DLD more globally. What are the potential or actual clinical implications of this work? The current study shows that statistical-learning tasks using tone stimuli can be used in conjunction with standardized assessment measures to differentiate children with DLD from children with typical language ability.

Rethinking attention in time: Expectancy violations reconcile contradictory developmental evidence.

Temporal expectations critically influence perception and action. Previous research reports contradictory results in children's ability to endogenously orient attention in time as well as the developmental course. To reconcile this seemingly conflicting evidence, we put forward the hypothesis that expectancy violations-through the use of invalid trials-are the source of the mixed evidence reported in the literature. With the aim of offering new results that could reconcile previous findings, we tested a group of young children (4- to 7-year-olds), an older group (8- to 12-year-olds), and a group of adults. Temporal cues provided expectations about target onset time, and invalid trials were used such that the target appeared at the unexpected time in 25% of the trials. In both experiments, the younger children responded faster in valid trials than in invalid trials, showing that they benefited from the temporal cue. These results show that young children rely on temporal expectations to orient attention in time endogenously. Importantly, younger children exhibited greater validity effects than older children and adults, and these effects correlated positively with participants' performance in the invalid (unexpected) trials. We interpret the reduction of validity effects with age as an index of better adaptation to the invalid (unexpected) condition. By using invalid trials and testing three age groups, we demonstrate that previous findings are not inconsistent. Rather, evidence converges when considering the presence of expectancy violations that require executive control mechanisms, which develop progressively during childhood. We propose a distinction between rigid and flexible mechanisms of temporal orienting to accommodate all findings.

Real-time comprehension of Spanish prepositions and prepositional locutions in bilingual children with developmental language disorder: A study based on eye-movement evidence.

BACKGROUND: Function words, and more specifically prepositions and prepositional locutions, are considered to be one of the most important difficulties for children with DLD. AIMS: To examine the capacity of bilingual children with developmental language disorder (DLD) to comprehend different Spanish prepositions and prepositional locutions in a simple sentence structure, for example, El gato está sobre la mesa/El gato está bajo la mesa (The cat is on the table/The cat is under the table). METHODS & PROCEDURES: We used simple sentence structures to reduce lexical difficulties in order to focus our evaluation strictly on the grammatical morphemes under study. A total of 96 Spanish and Catalan-speaking participants, divided into four groups, were evaluated in an eye-tracking psycholinguistic experiment: 24 children with DLD (average age = 7.8 years, age range = 4.6-12.6), 24 children with the same chronological age (average age = 7.8 years, age range = 4.6-12.2), 24 children with the same linguistic level (average age = 6.8 years, age range = 4.6-9.4) and 24 adults (average age = 22.5 years, age range = 18-30). OUTCOMES & RESULTS: The empirical data show that, despite some differences, bilingual children with and without DLD can comprehend Spanish prepositions and prepositional locutions under the current experimental conditions. CONCLUSIONS & IMPLICATIONS: Our results suggest that the capacity of bilingual children with DLD to comprehend Spanish prepositions and prepositional locutions in real time and within simple sentence structures is preserved. What this paper adds What is already known on the subject The empirical literature indicates that children with DLD show important errors in the production of functional words in general, and prepositions in particular. However, unlike other grammatical morphemes (such as clitic pronouns and articles), prepositions have been less studied, and the few existing studies have focused on the dimension of language production, not comprehension. What this paper adds to existing knowledge The present study, composed of two experimental tasks, seeks to determine to what extent the observable difficulty in the linguistic production of prepositions is also present in the comprehension of children with DLD. The empirical results suggest a less atypical comprehension in comparison with our initial hypothesis, and the differences that appear between the two tasks, allow us to formulate a theoretical interpretation regarding the mechanisms of their understanding. Thus far, we are not aware of other studies that have evaluated in real time the comprehension of prepositions and prepositional locutions in parallel. Clinical implications of this study Results suggest the presence of a more preserved comprehension of prepositions and prepositional locutions, at least in real-time experimental conditions (eye-tracking) and in simple sentence structures. A less atypical comprehension raises the possibility of a better prognosis for children with DLD. Working with comprehension of simple sentences and the gradual addition of more difficult grammatical morphemes could help to enhance the comprehension of a growing complex grammar.

"El nen s'ha menjat una aranya": The development of narratives in Catalan speaking children.

The production of a well-constructed narrative is the culmination of several years of language acquisition and is an important milestone in children's development. There is no current description of narrative development for Catalan speaking children. This study collected elicited narratives in Catalan from 118 children aged 4;0-10;11. Narratives were scored for macrostructure and microstructure. Narrative scores improved with age with maximum performance for macrostructure by 9 years. Children's ability to use micro-structural components of Catalan is variable with some developments continuing beyond 9 years. The results are discussed in relation to theoretical arguments about universal and specific features of narrative development. We conclude by highlighting the usefulness of the new test for future language assessment of children acquiring Catalan.

Exploring Spanish writing abilities of children with developmental language disorder in expository texts.

Introduction: Numerous studies have shown that children with developmental language disorder (DLD), in addition to oral language difficulties, exhibit impaired writing abilities. Their texts contain problems in grammar, organization, cohesion, and length of written output. However, most of these studies have been conducted with English speakers. English is characterized by complex phonological structure, opaque orthography, poor morphology and strict word order. The aim of this research is to observe the writing abilities of children with DLD in a language with simple phonological structure, transparent orthography, rich morphology and flexible word order like Spanish in the production of expository texts. Methods: Twenty-six children with DLD (mean age in months = 128.85) and 26 age-and sex-matched typically developing (TD) children (mean age in months = 124.61) wrote an expository text about their favorite animal. Results: In order to analyze how the two groups plan and encode written texts, we looked at word frequency and sentence structure, grammatical complexity and lexical density, and omissions and errors. Compared to the TD group, the children with DLD omitted more content words; made more errors with functional words, verb conjugation and inflectional morphemes, and made a large number of spelling errors. Moreover, they wrote fewer words, fewer sentences, and less structurally and lexically complex texts. Discussion: These results show that children with DLD who speak a transparent orthography language such as Spanish also have difficulties in most language areas when producing written texts. Our findings should be considered when planning and designing interventions.

Perception of audio-visual speech synchrony in Spanish-speaking children with and without specific language impairment.

Speech perception involves the integration of auditory and visual articulatory information, and thus requires the perception of temporal synchrony between this information. There is evidence that children with specific language impairment (SLI) have difficulty with auditory speech perception but it is not known if this is also true for the integration of auditory and visual speech. Twenty Spanish-speaking children with SLI, twenty typically developing age-matched Spanish-speaking children, and twenty Spanish-speaking children matched for MLU-w participated in an eye-tracking study to investigate the perception of audiovisual speech synchrony. Results revealed that children with typical language development perceived an audiovisual asynchrony of 666 ms regardless of whether the auditory or visual speech attribute led the other one. Children with SLI only detected the 666 ms asynchrony when the auditory component preceded [corrected] the visual component. None of the groups perceived an audiovisual asynchrony of 366 ms. These results suggest that the difficulty of speech processing by children with SLI would also involve difficulties in integrating auditory and visual aspects of speech perception.

The formulation of argument structure in SLI: an eye-movement study.

This study investigated the formulation of verb argument structure in Catalan- and Spanish-speaking children with specific language impairment (SLI) and typically developing age-matched controls. We compared how language production can be guided by conceptual factors, such as the organization of the entities participating in an event and knowledge regarding argument structure. Eleven children with SLI (aged 3;8 to 6;6) and eleven control children participated in an eye-tracking experiment in which participants had to describe events with different argument structure in the presence of visual scenes. Picture descriptions, latency time and eye movements were recorded and analyzed. The picture description results showed that the percentage of responses in which children with SLI substituted a non-target verb for the target verb was significantly different from that for the control group. Children with SLI made more omissions of obligatory arguments, especially of themes, as the verb argument complexity increased. Moreover, when the number of arguments of the verb increased, the children took more time to begin their descriptions, but no differences between groups were found. For verb type latency, all children were significantly faster to start describing one-argument events than two- and three-argument events. No differences in latency time were found between two- and three-argument events. There were no significant differences between the groups. Eye-movement showed that children with SLI looked less at the event zone than the age-matched controls during the first two seconds. These differences between the groups were significant for three-argument verbs, and only marginally significant for one- and two-argument verbs. Children with SLI also spent significantly less time looking at the theme zones than their age-matched controls. We suggest that both processing limitations and deficits in the semantic representation of verbs may play a role in these difficulties.

Effect of verb argument structure on picture naming in children with and without specific language impairment (SLI).

BACKGROUND: This study investigated verb argument structure effects in children with specific language impairment (SLI). AIMS: A picture-naming paradigm was used to compare the response times and naming accuracy for nouns and verbs with differing argument structure between Spanish-speaking children with and without language impairment. METHODS & PROCEDURES: Twenty-four children with SLI (ages 5;3-8;2 [years;months]), 24 age-matched controls (ages 5;3-8;2), 24 MLU-w controls (ages 3;3-7;1 years), and 31 adults participated in a picture-naming study. OUTCOMES & RESULTS: The results show all groups produced more correct responses and were faster for nouns than all verbs together. As regards verb type accuracy, there were no differences between groups in naming one-argument verbs. However, for both two- and three-argument verbs, children with SLI were less accurate than adults and age-matched controls, but similar to the MLU-matched controls. For verb type latency, children with SLI were slower than both the age-matched controls and adults for one- and two-argument verbs, while no differences were found in three-argument verbs. No differences were found between children with SLI and MLU-matched controls for any verb type. CONCLUSIONS & IMPLICATIONS: It has been shown that the naming of verbs is delayed in Spanish children with SLI. It is suggested that children with SLI may have problems encoding semantic representations.

Online Comprehension of Verbal Number Morphology in Children With Developmental Language Disorder: An Eye-Tracking Study.

PURPOSE: Previous studies have raised the possibility of preserved language comprehension in children with developmental language disorder (DLD) in online tasks and within simple sentence structures. Consequently, we evaluated the capacity of children with DLD to comprehend verbal number agreement in simple sentence structures (i.e., verb-object-subject and verb-subject). METHOD: Using an eye-tracking methodology, we conducted two psycholinguistic experiments with 96 Spanish- and Catalan-speaking participants. The sample was distributed into four groups: 24 children with DLD (age range: 4;6-12;6 [years;months]; average age = 7;8 [years;months]), 24 children with the same chronological age (4;6-12;2, 7;8), 24 children with the same linguistic level (4;6-9;4, 6;8), and 24 university students as language experts (18-30, 22;5). RESULTS: The experimental data indicate that children with DLD can comprehend verbal number agreement at least under the present experimental conditions. CONCLUSION: The empirical outcomes suggest that number morphology comprehension by children with DLD might be more typical than what it is generally considered to be.

Do children realize that pretend emotions might be unreal?

This research is aimed at comparing children's understanding of the distinction between external and internal emotion in deception and pretend play situations. A total of 337 children from 4 to 12 years of age participated in the study. Previous research suggests that in deception situations this understanding is very rudimentary at the age of 4 years, whereas 6-year-olds can articulate it in words. In the present work the children were asked to make this distinction in pretend play or deception tasks. The results show that in pretend play situations children start making this distinction at the age of 6 years, and their performance is better when the simulated emotion is negative rather than positive. These findings suggest that 4-year-olds are not aware that the emotions expressed in pretend play situations might be different from internal emotions.

Narrative comprehension and production in children with SLI: an eye movement study.

This study investigates narrative comprehension and production in children with specific language impairment (SLI). Twelve children with SLI (mean age 5;8 years) and 12 typically developing children (mean age 5;6 years) participated in an eye-tracking experiment designed to investigate online narrative comprehension and production in Catalan- and Spanish-speaking children with SLI. The comprehension task involved the recording of eye movements during the visual exploration of successive scenes in a story, while listening to the associated narrative. With regard to production, the children were asked to retell the story, while once again looking at the scenes, as their eye movements were monitored. During narrative production, children with SLI look at the most semantically relevant areas of the scenes fewer times than their age-matched controls, but no differences were found in narrative comprehension. Moreover, the analyses of speech productions revealed that children with SLI retained less information and made more semantic and syntactic errors during retelling. Implications for theories that characterize SLI are discussed.

Sociodemographic and Pre-Linguistic Factors in Early Vocabulary Acquisition.

Here, we studied the beginnings of language development, jointly assessing two groups of precursors, sociodemographic and pre-linguistic, that have previously been studied separately. Thus, the general objective of this study was to explore which factors best explained the acquisition of initial expressive vocabulary. The sample consisted of 504 participants from Catalan-speaking homes with ages ranging between 10 and 18 months. The data were obtained through the MacArthur-Bates Communicative Development Inventories (MCB-CDIs). Vocabulary development shows a lexical spurt at 17 months. Regression analyses show that pre-linguistic factors have more explanatory power of than sociodemographic ones. Within the sociodemographic variables, age, birth order and birth weight explain part of the vocabulary variance. With respect to pre-linguistic variables, imitation, late gestures and phrase comprehension are predictors of the initial vocabulary acquisition. Specifically, imitation and late gestures were the pre-linguistic behaviours that made it possible to distinguish between children with higher and lower levels of vocabulary. We discussed these findings in relation to their relevance for language acquisition and for the early assessment of linguistic competence.

Vocabulary Abilities and Parents' Emotional Regulation Predict Emotional Regulation in School-Age Children but Not Adolescents With and Without Developmental Language Disorder.

A comprehensive approach, including social and emotional affectations, has been recently proposed as an important framework to understand Developmental Language Disorder (DLD). There is an increasing considerable interest in knowing how language and emotion are related, and as far as we know, the role of the emotional regulation (ER) of parents of children with and without DLD, and their impact on their children's ER is still unknown. The main aims of this study are to advance our knowledge of ER in school-age children and adolescents with and without DLD, to analyze the predictive value of expressive and receptive vocabulary on ER in school-age children and adolescents, and to explore parental ER and their effect on their children's and adolescents' ER. To cover all objectives, we carried out three studies. In the first and second study, expressive and receptive vocabulary were assessed in wave 1, and ER (Emotional Regulation Checklist -ERC- for children and Emotion Regulation Scale -DERS- for adolescents) was assessed in wave 2, 4 years later. Participants in the first study consisted of two groups of school-aged children (13 had DLD and 20 were typically developing children -TD). Participants in the second study consisted of two groups of adolescents (16 had DLD and 16 were TD adolescents). In the third study, the ER of 65 of the parents of the children and adolescents from study 1 were assessed during wave 2 via self-reporting the DERS questionnaire. Results showed no significant differences in ER between DLD and TD groups neither in middle childhood nor in adolescence. Concerning vocabulary and ER, expressive language predicted ER in school-age children but not in adolescents. Finally, parental ER explained their school-age children's ER, but this was not the case in adolescents. In conclusion, the present data indicated that expressive vocabulary has a fundamental role in ER, at least during primary school years, and adds new evidence of the impact of parents' ER upon their children's ER, encouraging educators and speech language pathologists to include parents' assessments in holistic evaluations and interventions for children with language and ER difficulties.

Consistency of a Nonword Repetition Task to Discriminate Children with and without Developmental Language Disorder in Catalan-Spanish and European Portuguese Speaking Children.

Nonword repetition has been proposed as a diagnostic marker of developmental language disorder (DLD); however, the inconsistency in the ability of nonword repetition tasks (NRT) to identify children with DLD raises significant questions regarding its feasibility as a clinical tool. Research suggests that some of the inconsistency across NRT may be due to differences in the nature of the nonword stimuli. In this study, we compared children's performance on NRT between two cohorts: the children in the Catalan-Spanish cohort (CS) were bilingual, and the children in the European Portuguese cohort (EP) were monolingual. NRT performance was assessed in both Spanish and Catalan for the bilingual children from Catalonia-Spain and in Portuguese for the monolingual children from Portugal. Results show that although the absolute performance differed across the two cohorts, with NRT performance being lower for the CS, in both Catalan and Spanish, as compared to the EP cohort in both, the cut-points for the likelihood ratios (LH) were similar across the three languages and mirror those previously reported in previous studies. However, the absolute LH ratio values for this study were higher than those reported in prior research due in part to differences in wordlikeness and frequency of the stimuli in the current study. Taken together, the findings from this study show that an NRT consisting of 3-, 4-, and 5-syllable nonwords, which varies in wordlikeness ratings, when presented in a random order accurately identifies and correctly differentiates children with DLD from TD controls the child is bilingual or monolingual.

Real time comprehension of Spanish articles in children with developmental language disorder: Empirical evidence from eye movements.

Function words and, more specifically, articles have been widely indicated as one of the main sources of difficulty for children with Developmental Language Disorder (DLD). The present study is the first to assess the online comprehension of Spanish articles in bilingual children with DLD. In an eye tracking experiment, we monitored participants' eye movements as they listened to Spanish articles embedded in structurally simple sentences. Ninety-six subjects from four different groups were evaluated: 24 children with DLD (average age 7;08), 24 children with the same chronological age (average age 7;08), 24 younger children matched for mean length utterance (average age 6;08), and 24 adults (average age 22;05). We calculated the proportion between the preference for the correct visual referent and a competitor object. Our results suggest that children with DLD are capable of timely comprehension of Spanish articles in real time and within simple sentence structures. However, we observed a strong effect of chronological age in the sample of interest; younger children with DLD are able to identify the correct referent, but this preference is weaker compared to the older children with DLD. We also observed local differences between the DLD group, and the other two children control groups, particularly when the chronological age group is introduced as a factor. These findings suggest a developmental trajectory that is different in the DLD group relative to children with typical language development. Notwithstanding, in spite of the article production difficulties previously reported, children with DLD in the present sample appear to be able to comprehend Spanish articles in the current experimental conditions.

Auditory word recognition of verbs: Effects of verb argument structure on referent identification.

Word recognition includes the activation of a range of syntactic and semantic knowledge that is relevant to language interpretation and reference. Here we explored whether or not the number of arguments a verb takes impinges negatively on verb processing time. In this study, three experiments compared the dynamics of spoken word recognition for verbs with different preferred argument structure. Listeners' eye movements were recorded as they searched an array of pictures in response to hearing a verb. Results were similar in all the experiments. The time to identify the referent increased as a function of the number of arguments, above and beyond any effects of label appropriateness (and other controlled variables, such as letter, phoneme and syllable length, phonological neighborhood, oral and written lexical frequencies, imageability and rated age of acquisition). The findings indicate that the number of arguments a verb takes, influences referent identification during spoken word recognition. Representational complexity and amount of information generated by the lexical item that aids target identification are discussed as possible sources of this finding.

The effects of bilingualism on conflict monitoring, cognitive control, and garden-path recovery.

Bilinguals demonstrate benefits on non-linguistic tasks requiring cognitive control-the regulation of mental activity to resolve information-conflict during processing. This "bilingual advantage" has been attributed to the consistent management of two languages, yet it remains unknown if these benefits extend to sentence processing. In monolinguals, cognitive control helps detect and revise misinterpretations of sentence meaning. Here, we test if the bilingual advantage extends to parsing and interpretation by comparing bilinguals' and monolinguals' syntactic ambiguity resolution before and after practicing N-back, a non-syntactic cognitive-control task. Bilinguals outperformed monolinguals on a high-conflict but not a no-conflict version of N-back and on sentence comprehension, indicating that the advantage extends to language interpretation. Gains on N-back conflict trials also predicted comprehension improvements for ambiguous sentences, suggesting that the bilingual advantage emerges across tasks tapping shared cognitive-control procedures. Because the overall task benefits were observed for conflict and non-conflict trials, bilinguals' advantage may reflect increased cognitive flexibility.

Do Children with SLI Use Verbs to Predict Arguments and Adjuncts: Evidence from Eye Movements During Listening.

Different psycholinguistic theories have suggested the importance of verb semantics in rapidly anticipating upcoming information during real-time sentence comprehension. To date, no study has examined if children use verbs to predict arguments and adjuncts in sentence comprehension using children with specific language impairment (SLI). Twenty-five children with SLI (aged 5 years and 3 months to 8 years and 2 months), 25 age-matched controls (aged 5 years and 3 months to 8 years and 2 months), 25 MLU-w controls (aged 3 years and 3 months to 7 years and 1 month), and 31 adults took part in the study. The eye movements of participants were monitored while they heard 24 sentences, such as El hombre lee con atención un cuento en la cama (translation: The man carefully reads a storybook in bed), in the presence of four depicted objects, one of which was the target (storybook), another, the competitor (bed), and another two, distracters (wardrobe and grape). The proportion of looks revealed that, when the meaning of the verb was retrieved, the upcoming argument and adjunct referents were rapidly anticipated. However, the proportion of looks at the theme, source/goal and instrument referents were significantly higher than the looks at the locatives. This pattern was found in adults as well as children with and without language impairment. The present results suggest that, in terms of sentence comprehension, the ability to understand verb information is not severely impaired in children with SLI.
