Mothers' utterances were measured during interactions with their 13-month-old infants and correlated with measures of infants' productive lexical development at 13 and 24 months. Correlations between maternal measures and infants' lexical development were lower for employed mothers than for mothers who were full-time caregivers. (BC)

This research review sought to discover the forms of family verbal interaction that nurture language development in infants and toddlers, the function of different family members in this process, and the role of environmental factors in language development. Results indicate that speech to a child is significantly different from speech to an…

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…

Examined the communicative behavior of 40 maltreated and nonmaltreated 31-month-old toddlers and their mothers. Results revealed that maltreated toddlers followed a pattern of shorter mean length of utterance, less descriptive speech, and proportionally less relevant speech. (RJC)

The ability of young children to communicate at the time they produce their first words was studied, with particular reference to the question of whether children are able to modify their requests depending on the adult's response. The subjects were four children ranging in age from 15 to 18 months; the data were their requests of adults coded…

Infants raised the pitch of their vocalizations when stimulated by vocalizing parents. Nonvocal stimulation did not repeat the effect. Intonation contours did not change during different conditions. The pitch of the parents' vocalizations also rose during vocal interaction. Changes in infant pitch were interpreted as a function of imitation.…

The relationship between speech perception and speech production was investigated, by comparing five six and seven-year-old Dutch children who misarticulated the final consonant cluster /-ts/ with three control groups. Results indicate that the poorer the articulation proficiency of a group, the more variability there was in both production and…

Reports on an experiment describing the lexical development of a hearing child with a deaf mother and hearing father. Data confirm previous findings that (1) sign emerges before spoken word, (2) acquisition stages are similar in ASL and spoken English, and (3) the child initially develops one lexical system. (Author/AM)

Discourse and conversational analysis methods were used in a qualitative reconstruction of one aspect of the regularities in the way 61 children "do" personal reference. Of particular interest was the development of two reference forms: minimization--preference for simple (one word) forms, or recipient design--reference forms indicating…

THE AIM OF THIS RESEARCH PROJECT WAS TO IDENTIFY THE ARTICULATORY INACCURACY PROFILES OF CHILDREN ACCORDING TO THE ETIOLOGY OF THE CONDITION PRODUCING THE SPEECH DIFFICULTY. DURING THE FIRST PHASE OF THE RESEARCH, A BATTERY OF TESTS TO PROVIDE INFORMATION ON THE ARTICULATORY PATTERNS, VERBAL INTELLIGENCE, AND AUDITORY PERCEPTION OF NORMAL CHILDREN…

This study investigated the role of gesture in communication development. Gestural categories, based on communicative function, were identified from longitudinal videotapes of one mother-child pair. The videotapes were made weekly or bi-weekly from the time the child was 13 months of age until she was 42 months of age. The results of the study…

After taking base rate measures of verbal behavior, using a specially devised Story Telling Test and selected sub-tests from the Illinois Test of Psycholinguistic Abilities, 34 children with a mean age of 4-4, attending a year-round Head Start program, were assigned to matched experimental and control groups. The children in the experimental group…

Concerned with educational problems associated with low socioeconomic status, this pilot study in linguistic ecology was designed to substitute hard data for speculation about the nature and frequency of verbal behavior in the world of the poor child. To avoid self-consciousness and any restrictions on movement of the subjects, a small…
