Analysis of characteristics of 53 children with specific language impairment (SLI), ages 4 to 9, suggested that family history is related to pattern of language performance. Children with deficits in only expressive language had a higher proportion of affected family members than did children with both expressive and receptive language deficits.…

This article reviews recent research on children's knowledge and acquisition of derivational morphology across studies of listening, speaking, reading, and spelling. The paper concludes that this dimension of language organization deserves more attention than it now receives in language instruction. (Author/JDD)

Focuses on a single rule of grammar to produce evidence of a memory system for language acquisition and processing that is modular; independent of real-world meaning; unaffected by frequency and similarity; sensitive to formal distinctions; more sophisticated than the explicitly-taught rules it subsumes; developed independently of ambient input;…

This study examined whether toddlers build a repertoire of words as integral sequences of gestures and then differentiate these sequences into their gestural and segmental components. Results demonstrate clear differences in duration and coordination of gestures between children and adults and a shift toward the patterns of adult speakers during…

Data from a transcript database of 12 children collected in 1-hour samples every month from 1;0 to 3;0 support the hypothesis that there should be strong differences in the frequency and types of errors between pronouns with suppletive nominatives and those without. The suppletive nominative forms "I" and "she" are blocked from overextension in a…

Analyzes the developing language of the author's preschool-age daughter to examine the role of language use in two different cultural contexts. Discusses code switching, and the role of narratives. (SR)

While children aged 1;10 and 2;1 show only a modest rate of mapping novel nouns onto unfamiliar rather than familiar objects, children aged 1;4 and 1;8 show a high rate. Two studies with young 2-year olds found the noun-mapping preference prevalent, but unless initial choices are strongly reinforced, increase in salience of familiar kinds lures…

A report of research on phonology consists of two parts. The first examines the direction in which syllables are "built"--whether the segment or the syllable came first. The first part looks at the effects that different forms of syllabification have on syllable structure, and explores which syllable structure accounts for most…

Children aged 2 - 4 were tested to determine the effects of plausibility on comprehension of negative statements. It was found that negatives about an exceptional item in an array, i.e. plausible negatives, were understood before implausible negatives. Other results are described and discussed. (Author/RM)

Data drawn from videotapes of children aged 20 to 32 months were analyzed for patterns in the use of various self-reference forms at an age when children rarely refer to others compared to their use at an age when children more regularly refer to others as main participants. First, the distribution of the forms…

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…

Two studies of the innovative semantic distinctions and innovative uses before the acquisition of conventional number classifiers by young Japanese children (aged 5-7 years) are discussed. The findings suggest that lexical acquisition is an intricate process which often requires more than simple mappings of forms onto categories, and that…

The purpose of this study was to gather information on the acquisition of non-Indo-European languages. The field work was conducted in the village of Faleasao on the island of Ta'u in the Manu'a group of American Samoa from June, 1968 to June, 1969. The data collected consists primarily of tape recordings of naturally occurring and elicited speech…

THE INSTRUCTIONAL RESEARCH, DEVELOPMENT, AND EVALUATION UNIT OF THE DADE COUNTY (FLORIDA) PUBLIC SCHOOLS CONSTRUCTED SEVERAL INSTRUMENTS TO MEASURE CHILDREN'S LANGUAGE DEVELOPMENT. FOUR OF THESE INSTRUMENTS WERE USED BY THE SPECIAL LANGUAGE TEACHER PROJECT IN A STUDY CONDUCTED FROM FEBRUARY TO MAY, 1967 IN DADE COUNTY SCHOOLS. THE OBJECTIVES OF…

Summarized in terms of competence and performance models is the development of questionning behavior in the language repertoire of retarded children. The role of questions, particularly WH questions, is reviewed in adult language (semantics and pragmatics) and children's language (receptive and expressive abilities). Discussed is research dealing…
