In spoken languages, children acquire locative terms in a cross-linguistically stable order. Terms similar in meaning to in and on emerge earlier than those similar to "front" and "behind," followed by "left" and "right." This order has been attributed to the complexity of the relations expressed by…

The study sought to understand the general trajectory of children's executive function, as well as whether there was heterogeneity among monolingual English-speaking and dual language learning children in their growth of executive function. In addition, the study examined whether monolingual English-speaking and dual language learning children…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

We used the elicited production task to explore the production of short and long passives in 15 Mandarin-speaking preschool children with Developmental Language Disorder (DLD; aged 4;2-5;11) in comparison with 15 Typically Developing Aged-matched (TDA) children (aged 4;3-5;8) and 15 Typically Developing Younger (TDY) children (aged 3;2-4;3). This…

Children who are deaf or hard of hearing (DHH) show delays in Theory of Mind (ToM) development. Complement sentences such as "Eliane says that Santa Clause exists" influence ToM performance. Can a training program targeting sentential complements enhance ToM? Twenty-one French-speaking DHH children (M[subscript age] = 8 years 11 months)…

Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

Previous studies suggest that age of acquisition affects the outcomes of learning, especially at the morphosyntactic level. Unknown is how syntactic development is affected by increased cognitive maturity and delayed language onset. The current paper studied the early syntactic development of adolescent first language learners by examining word…

The aim of this research was to assess global and socio-emotional development and infant's language of caregivers by means of the third edition of Bayley Scales of Infant and Toddler Development. Literature points peculiarities on the institutional setting and that presence or absence of mother can impact infant's development in several forms.…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

Background: Several studies show that socio-economic status (SES) is related to the developmental trajectories of children with typical development (TD). However, few studies have analysed this relationship regarding children with neurodevelopmental disorders such as Down syndrome (DS). In this paper, we analyse the impact of SES in the…

The present study is designed to understand the adjustment of visually impaired students, attending the special and the integrated schools. This study has been conducted on the students of 60 visually impaired students, aged 14-16 years, attending special and the integrated schools in the selected schools of Varanasi city, UP, India. The method of…

Play is a powerful influence on children's learning and parents can provide opportunities to learn specific content by scaffolding children's play. Parent-child synchrony (i.e., harmony, reciprocity and responsiveness in interactions) is a component of parent-child interactions that is not well characterized in studies of play. We tested whether…

The present study aimed at investigating whether L2 learning affects phonological short-term and working memory and first language (L1) development. The performance of a group of 31 4- to-5-year-old sequential bilinguals attending an International School on tasks assessing phonological short-term and working memory and linguistic performance in L1…

This study aimed at investigating the similarities and differences between Vygotsky's perspectives on child language development with nativism and behaviorism. Proposing the idea of the Zone of Proximal Development, Vygotsky emphasized the role of collaborative interaction, scaffolding, and guided participation in language learning. Nativists, on…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…
