Whereas middle-aged individuals tended to group the entire stimulus array into piles of similar items, the elderly individuals grouped very much as young children do--arranging only a portion of the stimulus array into elaborate designs. (Authors)

Study concerned with the effects of procedural differences on the classification of geometrical stimuli. (Author)

Investigates why children under eight years of age show categorical clustering above chance expectations in free recall, when such organization does not correlate with recall. Six-year-old children and adults were tested for memory of 24 pictures of categorizable items. Proportion of items recalled in category strings and number of strings of each…

Seventy-two first grade students and 72 freshman college students participated in a study designed to test the hypothesis that the younger the child, the more perceptible are the attributes used in judging equivalence in sorting tasks. (BD)

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)

Study concerned with the question of why older children remember more in categorized free recall. (Authors/MB)

Results indicated that availability of categories rather than frequency of words seemed most crucial in determining developmental changes in clustering efficiency. (Authors)

Investigated the development and fragmentation of categories over chronological and mental age without the requisite of free recall. Kindergarten, fourth grade, ninth grade and retarded students labeled and categorized chromatic slides of picturable objects. (GO)

Study compared the relative power of the Taxonomic, Semantic Differential, and Sense Impression categories in the recall behavior of children. (Authors)

A grouping task revealed a chronological progression: color and form determined the 4-year-old children's grouping about equally; form dominated in the 5-year-olds; and 9-year-olds grouped primarily by conceptual attributes. Performance on a memory task showed the developmental shift from color to form to concept, while cued recall showed…

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 paper examines several recent lines of research concerning category clustering and describes an alternative to the standard category clustering procedure used to study recall organization in younger children. The specific issue considered is the age at which children first show evidence of spontaneous category clustering in their free-recall.…

The present study investigated the relationship between developmental shifts in the organization of materials and developmental changes in deliberate strategy use. Second- and fourth-grade children were presented with clusterable sort/recall lists representing the factorial combinations of high and low inter-item association and high and low…

During socialization, individuals begin to understand increasingly broader and more abstract units of personal and social reality. Subjects (N=97) ranging in age from 13 to late middle age completed a linguistic task in which they could impose higher order conceptions on lower order descriptions by identifying different level similarities within…
