Fundamental frequency, duration, and amplitude measures were extracted from stressed and unstressed syllables in interword and intraword comparisons. Analysis of target stress patterns revealed no difference between acoustic marking of stress by 6 adults and 22 toddlers. Findings indicate that children generally control these variables to derive…

This study examined effects of familiarity with a speech target on coarticulation magnitude in 30 young children and 10 adults. Children exhibited a greater effect of a following vowel on the preceding fricative than did adults. Nonmeaningful production items exhibited greater effects of the vowel on the preceding fricative than did meaningful…

This investigation addresses problems of defining verbal imitation, and suggests solutions by analyzing verbal interactions between two children and their mothers. Children were between 18 and 35 months old, with a mean length of utterance between 1.4 and 4.2 morphemes. Analyses focus upon the uses these children made of maternal models; 10…

The study investigated the effectiveness of a pragmatic language function protocol with a sample of 240 normal preschool children, aged 2-5, in a structured setting. The protocol was shown to be used reliably and was sensitive to differences in the mastery of language skills of normal children of different ages. (Author/JDD)

Reports on data collected in nine age ranges from 18 months to 71 months that examined children's ability to understand emotion-descriptive adjectives when used by adults and their own use of these words in productive vocabulary. (HOD)

Explores the underlying knowledge that children have about the relationship between the structure of requests and the relative status of speakers and listeners. Shows that the three age groups (preschoolers, 5-year-olds, and 10-year-olds) could systematically differentiate the requests by means of syntactic directness or semantics. (HOD)

Spanish-speaking children of Mexican descent living in California were tested on the acquisition of 18 Spanish consonants. The 120 subjects (aged 3 to 5:7 years) were equally divided into eight age groups, and the median ages (50%) and upper age limits (90%) of customary production of each consonant were determined.
