Today, L.S. Vygotsky's concept of a 'zone of proximal development' (ZPD) is often used to just mean best practices in early years teaching, like scaffolding. But in his original theory, the zones linked age periods distinguished by age-specific neoformations -- one of which was the formation of concepts at adolescence. So Vygotsky rejected Stern's…

Previous studies found that bilingual children and adults with typical language development (TLD) perform better than monolinguals in novel word learning, but show lower scores on lexical retrieval tasks (e.g., naming known words). Children with developmental language disorder (DLD) lack in their abilities in both tasks compared with children with…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

With the rapid increase in the diagnostic rates of autism spectrum disorder (ASD), there has been a growing need for evaluating the trends in training natural change agents to implement behavioral interventions and coming to a consensus on training procedures that are efficacious, efficient, and accessible. The purpose of this multiple manuscript…

Socioeconomic status (SES) has been shown to influence language skills, with children of lower SES backgrounds performing worse on language assessments compared to their higher SES peers. While there is abundant behavioral research on the effects of SES, whether there are differences in the neural mechanisms used to support language skill is less…

Scholars debate whether musical and linguistic abilities are associated or independent. In the present study, we examined whether musical rhythm skills predict receptive grammar proficiency in childhood. In Experiment 1, 7- to 17-year-old children (N = 68) were tested on their grammar and rhythm abilities. In the grammar-comprehension task,…

Although rapid automatized naming (RAN) is one of the best predictors of reading across languages, its nature remains elusive. In the present study, we aim to elucidate the nature of RAN by examining the cognitive and environmental correlates of RAN. One hundred forty-one second-year kindergarten Chinese children (71 girls, 70 boys; mean age =…

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…

Background: The literature on input addressed to children with specific language impairment (SLI) has shown contrasting results on the role that parents assume during conversational interactions. Some studies have shown that parents compensate for the child's linguistic limitations. In contrast, other studies have indicated that mothers are…

This study examined the preschool predictors of elementary school narrative writing skills. The sample included 65 typically developing African American children, ranging in age from 5.0 to 5.5 years, and was 44.6% male. Targeted preschool predictors included measures of phonological processing, core language abilities, prereading skills, and…

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two-character…

The relation of social and linguistic input measures to early vocabulary development was examined in 30 low-income African American mother-infant pairs. Observations were conducted when the child was 0 years, 1 month (0;1), 0;4, 0;8, 1;0, 1;6, and 2;0. Maternal input was coded for word types and tokens, contingent responsiveness, and…

The use of four types of psychological state words (physiological, emotional, desire, and cognitive) during mother-child play sessions at ages 3, 4, and 5 years was examined in 30 children diagnosed with delayed expressive language at 24-31 months and 15 age-matched comparison children with typical development. The children's mean length of…

Examines mothers' discourse in joint picture book reading in terms of the level of abstract thought it requires the child to make and compares this with language used in an interactive, product-oriented task, modelling a clown using play-doh. (39 references) (GLR)

Research on the development of efficiency in spoken language understanding has focused largely on middle-class children learning English. Here we extend this research to Spanish-learning children (n=49; M=2;0; range=1;3-3;1) living in the USA in Latino families from primarily low socioeconomic backgrounds. Children looked at pictures of familiar…
