Is noun dominance in early lexical acquisition a widespread or a language-specific phenomenon? Thirty Singaporean bilingual English-Mandarin learning toddlers and their mothers were observed in a mother-child play interaction. For both English and Mandarin, toddlers' speech and reported vocabulary contained more nouns than verbs across book…

This paper reports on an original study designed to investigate age-related change in the way French children produce speech during oral narrative, considering both prosodic parameters -- speaking rate and duration of the prosodic speech unit -- and linguistic structure. Eighty-five French children aged four to eleven years were asked to tell a…

This study examined the relations between receptive language development and other developmental domains of preschoolers from low-income families, through an inter-cultural perspective involving the United States and Turkey. A total of 471 children and their caregivers participated in Turkey, while 287 participated in the United States. Children's…

Pierce "et al." (2017) have proposed that variations in the timing, quality and quantity of language input during the earliest stages of development are related to variations in the development of phonological working memory and, in turn, to later language learning outcomes. To examine this hypothesis, three groups of children who are…

Cross-linguistic studies have shown that typically developing children have difficulties comprehending non-canonical structures. These findings have been interpreted within the Relativized Minimality (RM) approach, according to which local relations cannot be established between two terms of a dependency if an intervening element possesses similar…

Research on sources of individual difference in parental Infant-Directed Speech (IDS) is limited and there is a particular lack of research on fathers' compared to mothers' speech. This study examined the predictive relations between infant characteristics and variability in paternal lexical diversity (LD) in dyadic free play with two-year-olds (M…

Establishing local coherence relations is central to text comprehension. Positive-causal coherence relations link a cause and its consequence, whereas negative-causal coherence relations add a contrastive meaning (negation) to the causal link. According to the cumulative cognitive complexity approach, negative-causal coherence relations are…

Parent report instruments adapted from the MacArthur-Bates Communicative Development Inventories (CDI) examined vocabulary development in children aged 0 ; 8 to 2 ; 6 for two Chinese languages, Mandarin (n = 1694) and Cantonese (n = 1625). Parental reports suggested higher overall scores for Mandarin- than for Cantonese-speaking children from…

To investigate the apparent delay in color naming by young children, this study compared natural-kind and color naming (and corresponding comprehension) by 48 young English children who completed testing four times over six weeks. Results indicated that, as opposed to the salience view, the apparent delay in color naming may be explained solely on…

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age less than 33 weeks and/or birth weight less than 1,500 grams) and a comparison sample of 102 children born full term…

Investigated the effect of language on Chinese-speaking children's performance on false-belief tasks under three between-subjects conditions. Chinese-speaking adults and young children responded to false-belief tasks. Results revealed a rapid developmental pattern in the children's understanding of false beliefs and suggested the important role of…

Investigated the use of relative clauses in French children's narrative monologues. Narrative texts, based on a picture book without text, were collected from monolinguals age 5, 7, and 10 years and adults. Researchers coded relative constructions. Use of relative clauses in general-discourse functions preceded use in more specific narrative…

Two studies investigated developmental changes, and inter-linguistic and inter-individual variations, in the expansion and composition of young French children's early lexicons. Results indicated that lexical productivity strongly increased with age, whereas lexical diversity showed little developmental progression. Inter-individual variability in…

Twenty-two Spanish-speaking children ages 3 to 6 years participated in an elicited production study designed to test whether children's ability to produce subjunctive relative clauses related to their ability to pass a false-belief task. Results indicated a strong correlation between children's ability to use the subjunctive mood in relative…

Pragmatic development requires the ability to use linguistic forms, along with non-verbal cues, to focus an interlocutor's attention on a referent during conversation. We investigate the development of this ability by examining how the use of demonstratives is learned in Turkish, where a three-way demonstrative system ("bu,"…
