Five experiments examined whether overt repetition (i.e., saying a word aloud) during exposure is critical to the expressive learning of new words. When participants did not engage in overt repetition during exposure, they nevertheless exhibited clear expressive learning, both with and without an accompanying semantics, indicating that overt…

Young children were found to overextend and underextend newly uttered but previously understood words. The data are discussed in terms of differences between children's and adult's word meanings and between comprehension and production. (Author)

The relationship of object permanence and classification skills to receptive and expressive language development was investigated in infants. Object permanence, classification, and parent-child verbal interaction ratings were about equally related to language comprehension functioning, while permanence was more strongly related to language…

An experiment was conducted to investigate the hypothesis that English cliches reflect sex-specific styles of speech and that sex-specificity of expressions is related to differential usage by male and female speakers. Hypotheses were derived from Tyler's claims that the "neutral sphere" is infused by the male style, rendering it an inhibiting…

The findings from research on written and oral summarization are discussed under three headings: summarizers' strategies, improving summarizers' performance, and the assessment of summary quality. Objective measures of summary quality used by researchers are described, and ways these measures could be adapted for use in higher education assessment…

LITERATURE REVIEWS PROVIDE BIBLIOGRAPHIES ON RELEVANT RESEARCH (68 RESEARCH, 1955-66) AND ON LANGUAGE AND MENTAL RETARDATION (149 CITATIONS, 1929-66). FURTHER PAPERS ON…

Research on reading has tried, and failed, to account for wide disparities in reading skill even among children taught by the same method. Why do some children learn to read easily and quickly while others, in the same classroom and taught by the same teacher, don't learn to read at all? In "Language Development and Learning to Read", Diane…
