Studies using the English and Spanish MacArthur Communicative Development Inventories demonstrated that the grammatical abilities of 20--30-month-old bilingual children were related more strongly to same-language vocabulary development than to broader lexical-conceptual development or maturation. First, proportions of different word types in each…

This paper reports on a study that examined both the concurrent and longitudinal connections between multiple components of the home environment and indicators of preschool-aged children's literacy and language development. Data were collected from 85 parents and their children at two different times. Results of structural path models indicated…

These are typical scenarios of children with hearing loss who are being included increasingly in early childhood settings. Recent federal legislation encourages states to develop programs to screen the hearing of all infants before they leave the hospital, and currently 39 states have adopted newborn infant hearing screening mandates (ASHA 2005).…

The current study examined whether socioeconomic status (SES) and chaos in the home mediate the shared environmental variance associated with cognitive functioning simultaneously estimating genetic influences in a twin design. Verbal and nonverbal cognitive development were assessed at 3 and 4 years for identical and same-sex fraternal twin pairs…

The basic properties of a dynamic systems approach of development are illustrated by contrasting two simple equations. One equation is characteristic of dynamic systems models. The other refers to what, for the sake of simplicity, is referred to as the standard developmental approach. We give illustrations from cognitive, language and social…

The purpose of this study was to determine how storytelling and story reading influence the language development and story comprehension of young children from 3 to 5 years of age. During the study, two groups of children heard the same 24 stories. Group A heard the stories told and Group B heard the stories read from a book. The language pre- and…

The development of oral language in classrooms has been an incidental occurrence historically. The amount of oral language that children have is an indicator of their success or struggle in school. To meet the needs of these children, teachers can make oral language development a primary focus for instruction. This article examines ways that…

This study examines how rapid automatized naming (RAN) components-articulation time and pause time-develop from kindergarten to the end of first grade and how RAN components are related to different reading measures and to RAN total time. Sixty-two children were administered RAN tasks in kindergarten and at the beginning and end of Grade 1.…

This paper presents a response to five commentaries on our article "An Analysis of Autism as a Contingency-Shaped Disorder of Verbal Behavior" (Drash & Tudor, 2004). One of the principal objectives of that article is to provide the behavior analysis community and the autism community with a conceptual basis for analyzing autism as a behavioral…

The study investigated whether young children's health status is significantly related to their performance on measures of intelligence, language, and behavior, as well as parents' concerns, stress, and perceptions of their children's development. One hundred twelve 3 to 5 year-old children, recruited from a large pediatric practice and three…

"Theory of mind" development is now an important research field in deaf studies. Past research with the classic false belief task has consistently reported a delay in theory of mind development in deaf children born of hearing parents, while performance of second-generation deaf children is more problematic with some contradictory results. The…

Several recent studies from our laboratory have shown that 14-month-old infants have difficulty learning to associate two phonetically similar new words to two different objects when tested in the Switch task. Because the infants can discriminate the same phonetic detail that they fail to use in the associative word-learning situation, we have…

This paper investigates the acquisition of compound vs. phrasal stress ("hot dog" vs. "hot dog") in English. This has previously been shown to be acquired quite late, in contrast to recent research showing that infants both perceive and prefer rhythmic patterns in their own language. Subjects (40 children in four groups the averages ages of which…

Recent studies have suggested that cultures vary in subtle ways in the talk about talk that children hear and learn to produce. Twenty-two three-year-old children and their families in respectively Oslo, Norway and Cambridge, Massachusetts were observed during mealtime with the aim of identifying talk-focused talk. The analysis distinguished talk…

It is a matter of debate whether the two differentiated grammatical systems in a bilingual child develop autonomously, or whether there is interdependence and in what areas (Genesee, 2001; Meisel, 2001). Extensive research is being carried out in the emergence of the two grammars, but not much attention has been given to the development of…
