Two experiments were conducted to test the hypothesis that category recall is related to the quantity conservation of mass, weight, and volume. The predicted association between conservation level and category recall was observed. (JMB)

An alternating sort-recall procedure was used in three experiments to train third-, fifth-, and seventh-grade students in the use of organizational techniques as memory aids. (Author/JMB)

Development of the ability to classify auditory patterns was studied at grades 2, 6, 10, and 12 and at adult age levels.

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)
