In two sentence repetition experiments, we investigated whether four- and five-year-olds master distinct representations for intransitive verb classes by testing two syntactic analyses of unaccusatives (Burzio, 1986; Belletti, 1988). Under the assumption that, with unaccusatives, the partitive case of the postverbal argument is realized only on…

Social deficits have been implicated in the language delays and deficits of children with autism (ASD); thus, the extent to which these children use language input in social contexts similarly to typically developing (TD) children is unknown. The current study investigated how caregiver input influenced the development of "wh"-question…

Because of its structural characteristics, specifically the prevalence of verb types in infant-directed speech and frequent pronoun-dropping, the Italian language offers an attractive opportunity to investigate the predictive effects of input frequency and positional salience on children's acquisition of nouns and verbs. We examined this…

This study provides the first systematic account of word-final cluster acquisition in bilingual children. To this end, forty Welsh-English bilingual children differing in language dominance and age (2;6 to 5;0) participated in a picture-naming task in English and Welsh. The results revealed significant age and dominance effects on cluster…

Fast mapping weaknesses in children with specific language impairment (SLI) may be explained by differences in disambiguation, mapping an unknown word to an unnamed object. The impact of language ability and linguistic stimulus on disambiguation was investigated. Sixteen children with SLI (8 preschool, 8 school-age) and sixteen typically…

The present study compared the performance of twenty-seven French-speaking internationally adopted (IA) children from China to that of twenty-seven monolingual non-adopted French-speaking children (CTL) matched for age, gender, and socioeconomic status on a Clitic Elicitation task. The IA children omitted significantly more accusative object…

The aim of this paper is to compare speech and co-speech gestures observed during a narrative retelling task in five- and ten-year-old children from three different linguistic groups, French, American, and Italian, in order to better understand the role of age and language in the development of multimodal monologue discourse abilities. We asked 98…

In Study 1 we analyzed Italian child-directed-speech (CDS) and selected the three most frequent active transitive sentence frames used with overt subjects. In Study 2 we experimentally investigated how Italian-speaking children aged 2;6, 3;6, and 4;6 comprehended these orders with novel verbs when the cues of animacy, gender, and subject-verb…

Languages typically express semantic components of motion events such as manner (roll) and path (down) in separate lexical items. We explore how these combinatorial possibilities of language arise by focusing on (i) gestures produced by deaf children who lack access to input from a conventional language (homesign); (ii) gestures produced by…

An utterance such as "Show me the large rabbit" potentially generates a "contrastive inference," i.e., the article "the" and the adjective "large" allow listeners to pragmatically infer the existence of other entities having the same noun (e.g. a "small" rabbit). The primary way to measure…

Eight children aged 4;1-8;1 and their primary caregivers participated in a study designed to evaluate their use of the onset cluster /str-/ in both read and conversational speech. The cluster is currently undergoing a reported sound change in many varieties of English, with the initial /s/ being retracted to [?]. The study compared the initial…

It is widely agreed that learning to read starts with the establishment of letter-to-phoneme correspondences. However, it is also widely agreed that prereaders do not have access to phoneme units. Here we show that the building of associations between letters and syllables, which we call the "syllabic bridge", might be a faster and more…

Links between young children's everyday use of mindful conversational skills and their success on laboratory tests of theory of mind understanding (ToM) were evaluated. Using published scales, teachers rated the conversational behavior and shyness of 129 children aged 60 to 101 months (M = 78·8 months) who were in their first years of primary…

Recent research on adult German suggests that speakers use particular pitch accent types to signal the information status of discourse referents. This study investigates to what extent German five- and seven-year-olds have acquired this mapping. Semi-natural speech data was obtained from a picture-elicited narration task in which the information…

When bilingual children enter formal reading education, host language proficiency becomes increasingly important. This study investigated the relation between socioeconomic status (SES), maternal language use, reading input, and vocabulary in a sample of 111 six-year-old children of first- and second-generation Turkish immigrant parents in the…
