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)

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)

Arguing that the failure of instructional materials is frequently due to misconceptions held by their developers concerning the nature of comprehension, this chapter examines the factors involved in comprehension and relates them to the design of instructional materials. Three types of errors in comprehension are discussed, and ways to avoid them…

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…

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…

Examines the understanding of the pragmatic function of mental terms ("think,""know,""guess") to express the relative certainty of 69 children aged 3-11. Results showed an improvement with age for the "know-think" and "know-guess" contrasts, but no improvement with age for 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…

Between their second and fifth years, young children learn approximately 15 new words a day. For every word the child hears, he or she must choose the correct referent out of an infinite set of candidates. An important problem for developmental psychologists is to understand the principles that limit the child's hypotheses about word meanings. A…

Types of utterances (with locative action utterances specifically differentiated) were evaluated in a language-impaired child tracked between one year, six months and three years of age. Comparison with utterances in other children suggests the importance of such a fine-grained analysis in detecting semantic properties of child language…

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…

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…

Two children (ages four and five) with word-finding deficits characterized largely by semantic substitutions participated in a treatment involving phonological information about target words. Treatment resulted in reduction not only of occasional phonological word-finding substitutions but also of the large number of semantic word-finding…

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…
