In Skinner's analysis of verbal behavior, three categories of environmental control over instances of verbal behavior appear to be relevant to the study of infant vocal development: the mand, the tact, and the echoic categories. Procedures used in the remediation of language deficiencies and procedures found in work in the area of language…

This study examined the social labels which are first used by infants, social differentiation on the basis of labeling behavior, and overgeneralization of social labels. Subjects were 81 infants from 9 to 36 months of age. The 9- to 24-month-olds were shown slides of themselves, their mothers, their fathers, and unfamiliar children, babies, and…

To determine the normal sequence of the development of Spanish phonology and Spanish grammatical patterns in the speech of native Spanish speakers, ages 2-5, a study of the acquisition of interrogative formation was undertaken. Two male and two females from each of nine age intervals between two and five were selected as informants; all were…

A study was conducted of the development of consonant clusters in the phonology of a native English-speaking child. His progress was studied over a year and a half period, in three one-month segments. His speech was recorded by tape and transcribed. Techniques used to elicit consonant clusters included real word imitation, imitation of nonsense…

To the question of whether Chomsky's hypothesized Language Acquisition Device (LAD) in young children is an adequate and feasible model of language acquisition, this paper answers that LAD should be reformulated so as to include semantics; that "informant presentation" rather than "text presentation" is responsible for language…

This analysis of the structure of children's narratives deals with material gathered from 96 children, aged 3 1/2 to 9 1/2 years, in conversations about events in which they were personally involved. Elements of the narratives and the structural relationship of these elements are examined. Three elements are discerned: (1) chronological…

This study focuses on children's reflectiveness about their drawings, and on the effect of other children's presence on the drawer's verbalizations about the drawing process and product. It was hypothesized that children would talk more about their representational efforts in the presence of other children, and that planning and evaluative or…

The purpose of this paper is to examine the status of deictic reference in the speech of 19 three-year-old Black children. The deictic verbs of motion are examined with reference to other aspects of the deictic system. The data for this study are approximately eight hours of spontaneous speech collected in a pre-school classroom. The hypothesis to…

The study summarized in this paper deals with the grammatical analysis of the spontaneous speech of approximately 150 children who are classified as mentally disabled; educable (I.Q. range 50-80). The performance of these mentally disadvantaged children is compared with the performance of 200 normally developing children by using a clinical…

Visual and verbal literacy skills are crucial to children because of their relationship to reading, and to adults because of their social utility. Such skills are, paradoxically, among those least often developed in a systematic fashion in elementary schools. One reason for this is that component subskills of visual and verbal literacy are…

This paper describes a study which examined the performance of 48 pairs of 18-month-old twins on the Mental Development Scale of the Bayley Scales of Infant Development to determine whether score differences would be found for the three subgroups of identical, fraternal same-sexed, and fraternal opposite-sexed twins. Of the 96 subjects, 46 (23…

Discusses the influence a first language can have on the acquisition of a second language. Includes some tentative proposals on the interaction of prior first-language knowledge and the creative construction process. (EKN)

While previous studies investigating sex differences in the growth of academic abilities have been inconsistent in their conclusions, sex differences have often been reported, particularly in the areas of verbal and mathematical achievement. Results from several longitudinal studies have suggested that these measured differences in achievement are…

The concept of consciousness played a central role in Vygotsky's research and theory. Unfortunately, with the advent of behaviorism, consciousness fell into disfavor. One of the major obstacles in studying consciousness is that there is no single acceptable definition of the term. Various researchers have dealt with five different aspects of…

In order to describe the developmental patterns of writing and rereading from writing of kindergarten children across group and individual contexts, a study asked 123 kindergarten children in Palatine, Illinois, to write and reread stories of their own composition over a school year. Children were asked to write in group classroom conditions at…
