Fricatives and affricates in different word positions and initial fricative clusters were elicited from three linguistically deviant children (ages five years, two months to seven years) and one normal child (age two years, nine months) by means of pictures depicting familiar objects. Data from two of the older children and the normal child are…

A longitudinal study of language development is being conducted in which ten recordings of spontaneous speech are being made of l28 children at 3-month intervals. Children were stratified with respect to age, sex, birth month, social and educational family background and family occupations. A matrix was constructed for two groups of children, with…

Traditionally linguists have considered pidgin languages as corrupted constructions of European vocabulary based on African or Asian syntax. Recent systematic studies of these languages show complex patterns of mutual influence on many levels. To explain the structural similarities of pidgin languages, some linguists, such as Keith Whinnom, have…

A study was conducted to determine criteria to measure successful language development and to determine what factors might be considered to be the determiners of this development. Subjects were 16 children, aged 3 years 3 months, selected on an intuitive basis from the 64 children in the older age group to represent the full range of development,…

Describes the structure and emergence of extended argument sequences produced by preschool children. Provides a system for analyzing turns that initiate, elaborate, and terminate argument sequences. Draws conclusions regarding the development of proficiency in producing argument and interaction. (PD)

Indicates that 18- to 20-month-old infants can detect the correspondence between auditorially and visually perceived speech; that is, they manifest some of the components related to lip-reading phenomena in adults. This demonstration of the bimodal perception of speech in infancy has important implications for social, cognitive, and linguistic…

Attempts to determine whether children can use social-pragmatic cues to determine "what kind" of referent, object, or action an adult intends to indicate with a novel word. Doubts that children assume that a novel word refers to whatever nameless object is present. Suggests that lexical acquisition rests fundamentally on children's…

Examines whether knowledge of functional properties of a referent for a new name influences children's first guesses about whether that name refers to an object or a substance. Suggests that children do not rely on a single source of information, but rather draw on various kind of information, including perceptual characteristics of the entities…

This study investigated whether mothers' responses to their infants' gestures play a role in their infants' vocabulary development. Eight infants were observed interacting at home with their mothers on 2 occasions, when the infants were 10 to 12 months old, and 16 to 18 months old. Videotapes of the observations were transcribed and coded for…

A study of the babbling and phonological development of 54 infants used half-hour videotape recordings of the children at play in their own homes. The vocal output was phonetically transcribed twice for interrater agreement, and analyzed for the consonants used five times or more in the child's vocal repertoire. These consonants were considered to…

This paper examines children's early attempts at describing events absent in space and time, referred to as the "reportative function." The first part of the paper offers some explanations for the late emergence of the reportative function in young children's speech. Part two presents examples of children's attempts to report past events…

A study of data on Japanese children shows that the development of verbs occurs at the same time as the development of nouns and may even precede it. The subjects for the study were two children who were learning Japanese as their first language. Four speech samples, taken between the ages of 22 and 28 months, were audiotaped and supplemented by…

The spontaneous speech of a Mohawk-speaking boy was recorded from age 2;10 to 4;1. Analysis of this speech indicated that certain verbal prefixes are acquired earlier than suffixes. The pronominal prefix of nouns, on the other hand, enters late. Yet, before the appearance of any nominal affix, the child already uses a pronominal possessive as a…

The verbal behavior of three children was sampled. The samples were analyzed to obtain a picture of three stages of the children's language development, specifically the interrogative structures. Each stage was about 4- or 5-months long, starting at the 18th to 28th month, depending upon the child's level of linguistic ability. The interrogative…

A study was conducted to determine whether the child expresses linguistic knowledge during the single-word period. The order of mention in 65 sets of successive single-word utterances from five children at Stage 1, two to four years old, were analyzed. To elicit speech, the children were shown line drawings representing such situations as animate…
