Few studies have focused on mechanisms of developmental change during the prelinguistic period. The lack of focus on early vocal development is surprising given that maternal responsiveness to infants during the first two years has been found to influence later language development. In addition, in a variety of species, social feedback is…

This article is about the contributions children make in clinical interviews. This issue is studied by re-analysing a selection of the empirical excerpts used by Piaget in his seminal book The Child's Conception of the World. The focus is on how children use language non-literally, and especially on how they use meta-communicative markers ("as…

Characterizing early communicative development in children with Autism Spectrum Disorders (ASD) is valuable for understanding profiles of ability in this population. The current investigation was modeled on Charman, Drew, Baird & Baird (2003b). Analyses explored parent report of early vocabulary, non-verbal communication, functional object use and…

There are many postulates of a relation between quality of attachment with theory of mind and language functions (e.g., de Rosnay & Hughes, 2006). The current study examined in longitudinal design how different patterns of attachment are associated with usage of internal state language at ages 17, 23, 30 and 36 months. Transcripts of mother-child…

In an investigation of discourse sensitivity, Catalan-speaking children aged 4 to 8 years were asked two different questions in a picture description task. One was a wide-focus question ("What is happening?"); the other was a narrow-focus question ("What is happening to 'the patient'?"). Children of all age groups displayed sensitivity to the…

From the beginning of life, a child's acts of meaning are joint constructions, enacted through dialogue between himself and a significant other by reference to whom he is achieving a personal identity. When the child begins to control his material environment, he begins the transition to systematic symbolic construction. At the same time, he is…

This study investigated the nature and extent of differences in young children's talk when they interact with mothers and peers. Sixteen girls between 2.5 and 3.5 years of age played twice with their mothers and twice with a peer. Play sessions were videotaped and coded according to measures of quantity and quality of talk. Results of measures of…

A study investigating the acquisition of empty categories (ECs) in Sinhala, a language of the Indo-Aryan family spoken in Sri Lanka, is reported in part. The results examined here concern ECs occurring in a subset of adverbial clause types differing with regard to the kinds of null subjects they permit, including those obligatorily coindexed,…

This examination focuses on the idea that child language acquisition is constrained by the same principles that have been found to hold on syllable structure across languages. First, a recently-proposed constraint on syllable structure, the Sonority Cycle, is outlined, and the way that it accounts for syllabic structure across languages is…

A study investigated children's use of three acoustic parameters (intensity, fundamental frequency, and duration) in the production of two-syllable nonsense words. Subjects were six children each at ages 2, 3, and 4 years with age-appropriate language skills and normal hearing sensitivity. An examiner produced eight novel two-syllable words of…

Designed to grade children's knowledge of commonly used instructional terms in a particular language arts program, the AIT consists of a verbal part and a situational part. Each part assesses the same commonly used instructional terms: word, begin, letter, name, makes sense, beginning sounds, print, trace, capital letter, rhyme, period, stands…

The use of observation of natural language interaction as a measure of language proficiency and the impact of discourse characteristics on children's use of Spanish and English as measured by length of utterances are examined. The goal of this observational approach to measuring language proficiency is to distinguish between the effects of change…

Dialogues of sets of socially similar twins are studied. The opinion that twins have slower syntactic development than non-twins is seriously questioned. Dialogues with twins saying the same utterance together, correcting each other, quarreling, playing verbal games, etc. are analyzed in their deep structure. (SCC)

Through discussion and illustrative events, an evolving segment of communication is described during the course of transition of one child's total communication system from the sensorimotor or gestural level at 12 months into the level of use of the adult words "more" and "mine," and associated utterances, at 24 months.

Results are reported of a study of voice onset time characteristics of stops in initial clusters in American English words produced by children and adults. (Author/RM)
