This study investigated the role of semantic analyzability in children's understanding of idioms with 80 children (kindergarten and grades 1, 3, and 4). Idioms varied in the degree that the meanings of their parts contributed to their figurative meanings. Findings indicated age differences with younger children better understanding the…

Two experiments examined children's semantic representations and semantic naming errors. Results suggested that functional and physical properties are core aspects of object representations in the semantic lexicon and that the degree of semantic knowledge makes words more or less vulnerable to retrieval failure. Discussion focuses on the dynamic…

Developmental differences in the relative salience of features in concept representations in semantic memory and their contributions to differences in cued recall were examined in two experiments. Subjects were second graders, fifth graders, and college students. Results showed that recall varied with feature salience, with salience greatest for…

Compares two types of semantic development (the acquisition of disappearance words and success-failure words) to performance on two types of cognitive tasks (object-permanence and means-ends tasks) among infants. (HOD)

Student understanding of 30 nontechnical words used in science was investigated. No significant differences were found between the understanding of nontechnical words in science or between the verbal reasoning ability of males (n=108) and females (n=89). Of the four different question formats, students had the most difficulty with the synonym…

Three experiments explored the development of formal logical reasoning between Grades 4 and 12 and the role of semantic content in the solution of Wason's (1966) selection task problems. Results suggest that formal logical reasoning is not generally present during the fourth or sixth grades and that formal logical competence becomes available in…

Students, ages 12, 15, 18, and 23 (n=60 per group), wrote definitions for 16 abstract nouns. Responses were analyzed for Aristotelian style. There was an increasing tendency for students to mention the appropriate category to which a word belongs, core features of the word, and subtle aspects of meaning. (DB)

As the first title in the new series, "New Directions in Communication Disorders Research: Integrative Approaches", this volume discusses a unique phenomenon in cognitive science, single-word reading, which is an essential element in successful reading competence. Single-word reading is an interdisciplinary area of research that incorporates…

Examines the quality of conversation produced by small groups of subjects in fifth, ninth, and twelfth grades and the last year of college. Results supported Piaget's sequence of conversational development. However, topical coherence apparently is not fostered by focused turns but emerges as a generalization of the normative constraints applying…

Investigates the role of intraverbal learning (a process through which semantic knowledge is acquired from purely linguistic information) in preschool children's acquisition of semantic concepts. Shows that the relative effectiveness of pictorial and intraverbal information depends on the child's age, the type of information supplied, and the…

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)
