This study examined the influence of cognate status and language distance on simultaneous bilingual children's vocabulary acquisition. It aimed to tease apart effects of word-level similarities and language-level similarities, while also exploring the role of individual-level variation in age, exposure, and nontarget language proficiency. Children…

Purpose: Play is a critical aspect of children's development, and researchers have long argued that symbolic deficits in play may be diagnostic of developmental disabilities. This study examined whether deficits in play emerge as a function of developmental disabilities and whether our perceptions of play are colored by differences in language and…

Although emerging evidence suggests that parental behavior is related to the development of child executive functioning (EF), the mechanisms through which parenting affects child EF have yet to be investigated. The goal of this study was to examine the potential mediating role of child language in the prospective relation between maternal autonomy…

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…

A study of spontaneous language use by elementary school children and teachers in a wide range of classroom activities used a combination of observation, audiotaping, videotaping, and interviews to examine more closely the role of dialect diversity in elementary education. The study provides a more accurate and complete record of classroom life…

Investigates the role of pupil language in classroom learning through an ethnographic study of one "good" teacher and her class, particularly three average and above-average pupils. (HOD)

Studies the simultaneous language development in American Sign Language and spoken English by a hearing girl. Findings show: (1) a mixture of oral and manual babbling, (2) a code-switching ability across modalities, and (3) a single syntactic system incorporating rules from both languages but with two separate lexicons. (Author/PJM)

A study was conducted to analyze the language behavior of mothers of children with normal language development and mothers of children with delayed language development as they interacted with their children to determine if the two groups of mothers provided different linguistic inputs for their children. Two randomly selected groups of children…

The purpose of this study was to investigate the linguistic differences in the spontaneous speech of language-deviant children in two very different situations. Spontaneous speech samples of eleven five-year-old language-deviant children were obtained from: (1) the traditional adult-child therapy situation using appropriate stimulus materials; and…

The purpose of this research was to frame a hypothesis accounting for the observed behavior of particular children in a contact language area, in an attempt to understand their linguistic learning processes. The community involved was the township of Benque Viejo at the Guatemalan frontier, and the four informants, aged 10-13, spoke varying…

Input language may have an effect on child development that goes far beyond language development alone. Language is the medium by which children acquire at least a portion of their sex role and social class or group characteristics, world view, and emotional and psychological well-being. Existing theories of psychological development ignore…

Observation of child language development is just one way to study how language changes over time. Developmental psycholinguistics shares much common ground with historical linguistics and with studies of languages in contact and the evolution of pidgins and creoles. By studying the way language changes, this paper focuses on clarifying the…

A descriptive case study reports and examines a five-year-old Finnish child's attainment of English language and communication skills during his first eight months in the United States, within a pragmatic theoretical framework, focusing on the various functions of utterances. The child's language usage is divided into social and egocentric speech…

Two studies were conducted to determine whether language as well as appearance cues would influence children's performance on a sex constancy task. In the first study, preschoolers and second graders participated in a sex constancy task in which different labels were used to refer to a picture of a boy or girl. The results showed that older…

Examines a series of naturally-occurring phone calls between a young child and his grandmother in the child's second language (L2), Portuguese. Notes that during the calls the child's L2 appears to increase in complexity, but is subsequently abandoned. Argues that this abandonment requires an examination of the language's role in the larger…
