Explored the effects of sorting methods upon the content of children's constructs. Results indicated that dyadic sorting and free response methods of construct elicitation differentially affect the types of constructs produced. (Author/BL)

Analysis of data collected from a Persian-English bilingual infant over 10 months beginning at age 9 months found that, in comparison to the monolingual child in a previous study by Halliday, both children developed pragmatic functions from a very early age. A categorization system is proposed to facilitate the analysis of child language…

This study evaluated the accuracy of automated methods of grammatical categorization ("tagging") of transcribed conversational language samples from 30 normally developing children. On a word-by-word basis, automated accuracy levels averaged 95.1%; accuracy of tagging whole utterances averaged 77.7%. Results suggest that further improvement of…

Reflects on researchers' conceptions about psychological growth over the last century. Discusses five themes relevant to developmental research: (1) the selection of phenomena for study; (2) the use of continuous dimensions or categories to describe children's characteristics; (3) continuity versus discontinuity in development; (4) the influence…

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…
