Os objetivos deste estudo foram correlacionar o desempenho de crianças com Distúrbio Específico de Linguagem (DEL) nas provas de memória de trabalho e de compreensão de sentenças e verificar, entre as duas provas de memória de trabalho utilizadas, qual a mais eficaz para discriminar crianças com DEL, quando comparadas a crianças com desenvolvimento típico de linguagem (DTL). Foram selecionadas 66 crianças, com idades variando de 37 meses (3:1 anos) a 131 meses (10:11 anos), divididas em três grupos de 22 crianças: um grupo experimental, de crianças com diagnóstico de DEL, e dois grupos controle, de crianças com desenvolvimento típico de linguagem e aprendizagem (DTLA). O primeiro grupo controle (n=22) foi pareado pela idade psicolinguística (GCIPL) e, o segundo (n=22), pareado pela idade cronológica (GCIC). A memória de trabalho foi obtida por meio das provas de repetição de pseudopalavras (PP) e de memória seqüencial para dígitos (ITPA DG), e a compreensão de sentenças por meio do \"Token Test\". A comparação entre o desempenho dos grupos foi realizada pelo teste \"t\" de Student, a correlação entre as provas de memória de trabalho e compreensão de sentenças foi realizada pela correlação de Pearson e, para verificar qual a melhor prova para discriminar as crianças com DEL, utilizou-se a curva ROC. As análises demonstraram que os sujeitos do grupo experimental apresentaram menor número de acertos nas três provas aplicadas (p<0,05). Foi encontrada correlação positiva entre as provas de memória de trabalho e a prova de compreensão de sentenças (PP --> r=0,42, p=0,049; ITPA DG --> r=0,74, p<0,001). Entre as duas provas relacionadas à memória de trabalho, a que demonstrou ter o melhor índice discriminatório de crianças com DEL foi a de pseudopalavras, com acurácia de 95%. Concluiu-se que houve correlação positiva entre a memória de trabalho e o aspecto da linguagem, compreensão, e que a melhor forma de discriminar crianças com DEL e crianças com DTL, entre as duas analisadas é a prova de pseudopalavras. / The objectives of this study was to correlate the children\'s performance with Specific Language Impairment (SLI) in the working memory and sentences comprehension tasks and to verify among the two working memory tasks used, which one is more effective to discriminate children with SLI, when compared to children with typical language development (TLD). It was selected 66 children with ages varying of 37 months (3:1 years) to 131 months (10:11 years), divided in 3 groups of 22 children, being one a experimental group of children with diagnosis of SLI and two control groups of children with typical development of language and learning (TDLA), being the first control group (n=22) matched by the psycholinguistic age (CGPLA) and the second (n=22) matched by the chronological age (CGCA). The working memory was obtained through the nonwords repetition (NW) and digit span (ITPA DG) tasks, and the sentences comprehension through \"Token Test\". The comparison among the groups performance was accomplished by the Student\'s t-test, the correlation between the working memory and sentences comprehension tasks was accomplished by the Pearson correlation, and to verify which one is the best task to discriminate the children with SLI, the ROC curve analyses was used. The analyses demonstrated that the experimental group subject presented smaller number of successes in the three applied tasks (p <0,05). It was found positive correlation between the working memory and sentences comprehension tasks (NW-->r=0,42, p=0,049; ITPA DG-->r=0,74, p <0,001). Among the two tasks regarding the working memory, the one that demonstrated to be the best discriminatory index of children with SLI was the NW, with accuracy of 95%. Therefore it is ended that there was positive correlation among the working memory and the aspect of the language, comprehension. And the best form of discriminating children with SLI and children with TLD, among the analyzed two, is the NW task.

Recent reports suggest that over half of the world's population regularly uses two or more languages (or dialects) in their daily lives. The U.S. Census Bureau reports 21.6% of the population communicates in a language other than English within their homes. Thus, it is essential to methodically investigate how language processing and learning vary between monolingual and bilingual individuals. To date, research on the effects of bilingualism on language processing has been inconsistent or conflicting. The present study was designed to empirically examine if bilingual speakers differ in language processing and comprehension compared to their monolingual counterparts. It was hypothesized that the bilingual switching process would impact language processing as measured by accuracy and reaction time (RT). A sample of 60 participants was used and consisted of 15 monolingual English speakers and 45 bilingual Spanish, French, and Arabic speakers. All participants completed a series of language decision tasks consisting of 44 congruent and incongruent sentences presented randomly and sequentially. Results showed that participants were more accurate in detecting incongruent than congruent sentences. Similarly, participants also responded faster to incongruent than congruent sentences. In addition, results also showed that participants had higher accuracy scores when the sentences were presented sequentially than randomly and responded faster when sentences were presented randomly than sequentially. Interestingly, results also showed a significant interaction between congruency and presentation mode on participants' accuracy scores. Tests of simple effects indicated that for the sequentially presented sentences, there was a significant difference between congruent and incongruent sentences. Similarly, for the congruent sentences, there was a significant difference between the sequentially and randomly presented sentences. Furthermore, our results also showed a significant interaction between congruency and presentation mode on participants' reaction time scores. Tests of simple effects indicated that participants had faster reaction time scores in the congruent sentences when they were presented randomly than sequentially. A series of General Linear Models (GLM) was conducted to examine the effects of language tested, congruency, and presentation mode on participants' accuracy scores. Results also showed a marginally significant interaction between congruency and language tested on accuracy and reaction time scores. Tests of simple effects indicated that only the Arabic speakers had significantly higher accuracy scores on concurrent than incongruent sentences. None of the other language groups had significant differences between congruent and incongruent accuracy scores for the other language groups. Finally, there was a significant interaction between congruency and language tested on participants' reaction time scores. Results showed that for the congruent sentences, French speakers had significantly faster reaction times than Spanish speakers and English speakers had significantly faster reaction times than Spanish speakers. However, English speakers had significantly faster reaction time scores for incongruent sentences than Arabic speakers. Both theoretical and practical implications are discussed, and future research directions are presented.

Le présent travail aborde le thème de la complexité sémantique dans le langage naturel, et il propose une hypothèse basée sur certaines caractéristiques des phrases du langage naturel qui déterminent la difficulté pour l'interpretation humaine.Nous visons à introduire un cadre théorique général de la complexité sémantique de la phrase, dans lequel la difficulté d'élaboration est liée à l'interaction entre deux composants: la Mémoire, qui est responsable du rangement des représentations d'événements extraites par des corpus, et l'Unification, qui est responsable de la combinaison de ces unités dans des structures plus complexes. Nous proposons que la complexité sémantique depend de la difficulté de construire une représentation sémantique de l'événement ou de la situation exprimée par une phrase, qui peut être récupérée directement de la mémoire sémantique ou construit dynamiquement en satisfaisant les contraintes contenus dans les constructions.Pour tester nos intuitions, nous avons construit un Distributional Semantic Model pour calculer le coût de composition de l'unification des phrases. Les tests sur des bases de données psycholinguistiques ont révélé que le modèle est capable d'expliquer des phénomènes sémantiques comme la mise à jour context-sensitive des attentes sur les arguments et les métonymies logiques. / The present work deals with the problem of the semantic complexity in natural language, proposing an hypothesis based on some features of natural language sentences that determine their difficulty for human understanding. We aim at introducing a general framework for semantic complexity, in which the processing difficulty depends on the interaction between two components: a Memory component, which is responsible for the storage of corpus-extracted event representations, and a Unification component, which is responsible for combining the units stored in Memory into more complex structures. We propose that semantic complexity depends on the difficulty of building a semantic representation of the event or the situation conveyed by a sentence, that can be either retrieved directly from the semantic memory or built dynamically by solving the constraints included in the stored representations.In order to test our intuitions, we built a Distributional Semantic Model to compute a compositional cost for the sentence unification process. Our tests on several psycholinguistic datasets showed that our model is able to account for semantic phenomena such as the context-sensitive update of argument expectations and of logical metonymies.

The oral language can be receptive and expressive: the receptive refers to the individual's ability to understand what he hears, that is, to understand oral language; the expressive represents the individual's ability to speak and communicate orally. The present study has the main objective to identify the extension of the receptive vocabulary of a group of Brazilian children of elementary school and its relation with the reading comprehension. For this it was necessary: to verify the extension of the receptive vocabulary of students from 1st to 5th year; check reading comprehension; to investigate the relationship between the extension of the receptive vocabulary and the reading comprehension; to verify how the variable age behaves in the receptive vocabulary analyzes, the reading comprehension and the relation between them. The sample came from a private school that serves children from families of high socioeconomic status in the city of São Paulo. 95 students participated from the 1st to 5th year of elementary school. Two instruments were used: Peabody Image Receptive Vocabulary Peabody Test and Reading and Sentence Comprehension Test (TELCS). The results obtained in this study were expressed as mean and standard deviation for each age group, school year, receptive vocabulary and reading comprehension test. An analysis of variance (ANOVA) was conducted and Tukey's post hoc test was also used. The evaluation of the receptive vocabulary with the Peabody test allowed us to conclude that there is a significant difference in Peabody performance according to age and school year. The results indicated that the children had a growing extension of the receptive vocabulary and level of reading comprehension, according to the increase of age and schooling. It was possible to observe a significant correlation between the extension of the receptive vocabulary and the level of reading comprehension of the 3rd, 4th, and 5th grade students / O domínio da linguagem é um dos elementos fundamentais para a vida social e fundamental nos processos de pensamento. A linguagem oral pode ser receptiva e expressiva: a receptiva refere-se à capacidade do indivíduo de compreender o que ouve, isto é, compreender a linguagem oral; a expressiva representa a habilidade do indivíduo para falar e se comunicar oralmente. O presente estudo tem por objetivo central identificar a extensão do vocabulário receptivo de um grupo de crianças brasileiras do Ensino Fundamental I e sua relação com a compreensão da leitura. Para isso foi necessário: verificar a extensão do vocabulário receptivo de alunos de 1º a 5º ano; verificar a compreensão da leitura; investigar a relação entre a extensão do vocabulário receptivo e a compreensão da leitura; verificar como se comporta a variável idade nas análises do vocabulário receptivo, na compreensão da leitura e na relação entre elas. A amostra foi proveniente de uma escola particular que atende crianças de famílias de nível socioeconômico alto da cidade de São Paulo. Participaram 95 alunos do 1º ao 5º ano do ensino fundamental. Foram utilizados dois instrumentos: Teste de Vocabulário Receptivo por Imagens Peabody e Teste de Leitura e Compreensão de Sentenças (TELCS). Os resultados obtidos neste estudo foram expressos sob a forma de média e desvio-padrão para cada faixa etária, ano escolar, vocabulário receptivo e teste de compreensão de leitura. Foi conduzida uma análise de variância (ANOVA) e utilizado também o teste post hoc de Tukey. A avaliação do vocabulário receptivo com o teste Peabody permitiu concluir que existe diferença significativa no desempenho no Peabody em função da idade e ano escolar. Os resultados indicaram que as crianças tiveram uma crescente extensão do vocabulário receptivo e do nível de compreensão de leitura, conforme o aumento da idade e escolaridade. Foi possível observar uma correlação significativa entre a extensão do vocabulário receptivo e o nível de compreensão de leitura dos alunos do 3º, 4º, e 5º ano

Ce travail est consacré à lévaluation de lhypothèse selon laquelle une limitation des capacités de traitement est à lorigine des troubles langagiers et non langagiers des enfants dysphasiques (ou enfants avec troubles spécifiques du langage, TSL). Les enfants présentant ces troubles montrent des limitations importantes de leurs compétences langagières sans raison apparente (absence de troubles auditifs, intellectuels et affectifs ou de lésions neurologiques). Ces dernières années, la spécificité des troubles langagiers a été remise en cause par de nombreuses études révélant lexistence de difficultés non spécifiquement linguistiques chez les enfants avec TSL, tels que des troubles attentionnels, exécutifs et moteurs. Certains auteurs ont formulé l'hypothèse quune limitation des capacités de traitement est à lorigine des troubles langagiers et non langagiers des enfants avec TSL. Selon cette hypothèse, les troubles langagiers observés chez ces enfants ne sont pas dus à un déficit des représentations linguistiques, mais reflètent une performance limitée par des difficultés à mobiliser lensemble des ressources, linguistiques et/ou non linguistiques, nécessaires à la réalisation de la tâche. Les recherches réalisées ont permis dévaluer si une telle hypothèse permet dexpliquer les performances observées dans deux épreuves linguistiques considérées par plusieurs auteurs comme des marqueurs comportementaux des TSL, les traitements morphosyntaxiques et la répétition de non-mots, en manipulant les processus recrutés ou la quantité de ressources nécessaires lors de la réalisation de la tâche. Nous avons également manipulé la complexité dans une épreuve non linguistique afin détudier si les limitations des capacités de traitement peuvent être considérées comme générales ou si elles savèrent limitées aux traitements linguistiques. Globalement, nos résultats ne sont pas compatibles avec lhypothèse dune limitation des capacités de traitement à lorigine des troubles linguistiques des enfants avec TSL. Ces enfants ne présentent pas de limitation importante de leurs capacités de traitements qui permette dexpliquer leurs troubles langagiers.

Diese Dissertation betrachtet die Beziehung zwischen Parser und Grammatik bei Muttersprachlern (Native Speakers, NS) und Heritage- (Erb-) Sprechern (HS) des Griechischen, indem sie die Mechanismen untersucht, die einer pseudo-Lizenzierung bei Verletzungen der Kongruenz des grammatischen Geschlechts zugrunde liegen. Diese Verletzungen sind Fehler, die auftreten, wenn eine intervenierende Phrase (Attraktor) nicht mit den Genusmerkmalen des Kopfnomens übereinstimmt, ein Phänomen, das in der Literatur (Gender-)Agreement Attraktion, hier Attraktion von Genuskongruenz, genannt wird. Die Dissertation testet, ob eine solche Attraktion von Genuskongruenz im Griechischen vorhanden ist und ob ein- und zweisprachige Muttersprachler gleichermaßen anfällig für Fehler bei der Attraktion sind. Die Dissertation untersucht für die Gruppe der HS außerdem die Genuskongruenz beim Echtzeit-Sprachverstehen und -produzieren. In der Arbeit zeige ich, dass sowohl NS als auch HS anfällig für Attraktionsfehler bei der Genuskongruenz sind. Das zeigen die Reaktionszeitmuster und die Urteile. Gleichzeitig zeigten bei mündlichen Erzählungen beide Sprechergruppen die gleichen Übergeneralisierungsmuster für maskulines Genus bei belebten Nomen sowie bei mündlichen Erzählungen und beschleunigten Grammatikalitätsurteilen für Neutrum bei unbelebten Nomen. Zusammengenommen deuten diese Ergebnisse darauf hin, dass NS und HS anfällig für die Attraktion von Genuskongruenz sind und dass beide Gruppen ähnliche Hinweise zum Abruf des Genus verwenden und somit ähnliche Attraktionsmuster aufweisen. HS unterscheiden sich jedoch von NS in der Verarbeitung der Genuskongruenz an sich, insbesondere bei femininen Kopfnomen (markiertes Genus) in Objekt-Klitika, was darauf hindeutet, dass sowohl Markiertheit als auch Kongruenz an den Schnittstellen die Leistung von HS beeinflusst. Wenn Fehler auftreten, folgen beide Gruppen den gleichen Mustern der Übergeneralisierung. / This dissertation explores the relationship between the parser and the grammar in Native Speakers (NSs) and Heritage Speakers (HSs) of Greek by examining the mechanisms underpinning the illusory licensing of gender agreement violations: errors occurring when an intervening phrase (attractor) mismatches the gender cues of the head noun, a phenomenon which is usually called (gender) agreement attraction. In this work, I show that both NSs and HSs are prone to gender agreement attraction errors in the nominal domain of Greek, as their reaction time patterns and (speeded or scaled) judgements revealed. At the same time, both groups showed the same overgeneralization patterns of the masculine value in agreement errors with animate nouns in their oral narrations, and of the neuter value with inanimate nouns in their oral narrations and their online speeded judgements. Taken together, these results suggest that NSs and HSs are prone to gender agreement attraction in Greek and that both groups employ retrieval cues similarly showing similar attraction patterns. However, HSs differ from NSs in the processing of gender agreement per se, particularly with feminine head nouns (marked gender value) on object-clitics, suggesting that markedness as well as agreement at Interfaces influence HSs’ performance. Finally, when errors occur, both groups follow the same overegeneralization patterns.

Bei der Verarbeitung transitiver Sätze verwendet der Parser verschiedene Informationen, wie die Wortstellung, die Belebtheit und die Kasusmarkierung der Argumente, um eine Repräsentation der im Satz beschriebenen Situation aufzubauen. Frühere psycholinguistische Arbeiten zeigen, dass zwei belebte Argumente in einem Satz zusätzliche Verarbeitungskosten verursachen, außer wenn andere Informationen die Zuweisung der grammatischen und thematischen Rollen an die Argumente erlauben. In kasusmarkierenden Sprachen wie Deutsch ist einer dieser Hinweise die morphologische Kasusmarkierung. Die meisten zweistelligen deutschen Verben weisen ihren Argumenten das kanonische Nominativ-Akkusativ-Kasusmuster zu. Eine kleine Gruppe von zweistelligen Verben weist jedoch das nichtkanonische Nominativ-Dativ-Muster zu. Diese Verben unterschieden sich in ihrer Syntax und Semantik von kanonisch transitiven Verben und verursachen beim Satzverstehen höhere Verarbeitungskosten. In dieser Dissertation wird untersucht, wie die Verarbeitung von Argumentbelebtheitskontrasten während der Satzverarbeitung vom verbalen Kasuszuweisungsmuster moduliert wird. Ich stelle die Ergebnisse vier verschiedener Experimente vor (selbstgetaktetes Lesen, Blickbewegungsmessungen und EKP-Messungen). Alle experimentellen Methoden zeigen, dass der Effekt der Argumentbelebtheitskonstraste mit dem Effekt des verbalen Kasuszuweisungsmusters interagiert. Die Ergebnisse zeigen ein detaillierteres Bild der Satzverarbeitung und tragen zur Vereinigung der Transitivätsbegriffe in theoretischer Linguistik und Psycholinguistik bei. / During the comprehension of transitive sentences, the parser uses different kinds of information like word order, the arguments'' animacy status and case marking to build a representation of the situation the sentence describes. Previous research in psycholinguistics has shown that two animate arguments in a sentence cause additional processing costs, unless other cues allow the assignment of grammatical and thematic roles to the arguments. In case-marking languages like German, one of these cues is morphological case marking. While most German verbs assign the canonical nominative-accusative case pattern to their arguments, a small group of verbs assign noncanonical nominative-dative. These verbs differ from standard transitive verbs both in their syntax and their semantics, and are known to cause higher processing cost during comprehension. This dissertation examines how the processing of argument animacy contrasts during sentence comprehension is modulated by the verbal case marking pattern. I report the results of four different experiments, using self-paced reading time measurements, eyetracking and ERP measurements. All experimental methods show that the effect of argument animacy contrasts interacts with the effects of the verbal case marking pattern. The findings add further details to the existing knowledge about sentence comprehension, and combine perspectives on transitivity from theoretical linguistics and psycholinguistics.
