The development of multiplicative classificatory skills in children between 4 and 9 years of age was investigated by means of two forms of the matrix-completion task. (Authors)

An investigation of the category-recall relationship using first, third, and fifth graders as subjects. Recall was found to be a function of the number of categories in the sort, and there were no differences in recall among the three retrieval conditions. (Author/SDH)

The most significant finding is that classification according to complete similarity not only occurs much earlier than reported by Inhelder and Piaget, but also does not follow the developmental course reported by Inhelder and Piaget. (Author)

Assessed organizational strategies for recall by comparing lists designed for recall by children in kindergarten, third and sixth grade with ordinary free associations, and by observing whether the lists served as units of organization in a subsequent free recall task. (Author/SDH)

An exploration of age-related characteristics of children's personal categorizing schemes and relationships between free recall clustering (measured in reference to these schemes), and the number of items recalled. The 60 subjects were from five grade levels: 1, 4, 7, 10 and college. (Author/SDH)

This research studied the effects of instructions on children's recall in a free recall learning task. Also investigated were developmental trends, including expected superiority of older children in recall and spontaneous formation of stable organizational groupings. A third area of study concerned the possibility that younger children benefit…

This study was designed (1) to determine differences in classificatory skills of low socioeconomic status children under intervention and non-intervention conditions; (2) to determine differences in classification skills of bilingual, biliterate, and monolingual students; and (3) to study differences in classificatory skills as a function of age.…
