Investigated Piaget's distinction between the roles of scheme and schema in memory. Proposed that schemas may vary within wide limits while the underlying schemes from which the schemas stem remain stable. Subjects were 78, 6-year-old children. (SDH)

Suggests that patterns of abilities are the best cross-cultural evidence for the effects of environment and culture upon memory development. An object and place recall task was administered to 5- and 7-year-old American and Guatemalan children. (Author/SDH)

Investigated two developmental implications: (1) that foci for color categories become established and stabilized earlier than boundaries, and (2) that focal judgments are always more stable than boundary judgments. Subjects were 20 kindergarteners, 40 third graders and 40 adults. (Author/SDH)

Compared the home environments and parent-child interaction patterns of 20 preschool language-delayed children, 20 normal preschoolers and 20 genetically handicapped children with Down's Syndrome. Data indicate that language delay had a stronger influence on mother-child relationship than did socioeconomic factors. (Author/SDH)

The analysis of logical and antilogical influences on preference made by Bradbury and Nelson is extended to a consideration of choices by children in kindergarten, Grade 4, and Grade 8. Conclusions are drawn concerning the dependence of intransitive preference on the collative variable of novelty in choice context. (Author/SDH)

Presents: (1) an outline of prototype age-related changes in cognitive structure; (2) an application of these interrelationships to some existent research and concepts in the abilities domain; and (3) a discussion of the multifactor approach in structuring age-related change to organismic views of cognitive development. (SDH)

Examined three dimensions of role taking (perceptual, cognitive and affective) and two dimensions of moral judgment (intentionality and restitution). (Author/SDH)

A total of 80 males and females (from 10 to 18 years old) were studied for explanations of task performance. No consistent age or sex differences were found. (SDH)

This study investigated the prediction that playful activity would increase the number of alternate uses that children would be able to give for objects which are not involved in that activity. Subjects were 36 white, middle-class preschoolers. (Author/SDH)

Reexamines the priority effect using proper controls for serial position bias. Subjects were preschool, second and sixth grade children, and adults. (SDH)

A study of the differences in the estimates given by older and younger adults of the ages of stimulus persons distributed across the age continuum. (SDH)
