Tested 63 kindergarten children on a spatial perspective task in which they copied the location and orientation of objects when the model and response spaces were aligned or when one was rotated 90 degrees or 180 degrees. (LLK)

Discusses the respective roles of rate of learning and level of cognitive development in determining intellectual performance in 156 normal and retarded children matched for mental age. (Author/LLK)

The olfactory acuity of 120 individuals ranging in age from 6 through 94 years was assessed by means of magnitude production in a simple motor task. (LLK)

Discusses the impact of role playing on the change of moral judgment maturity in 96 college students. Subjects showed both immediate and delayed increases in moral judgment maturity when role playing a moral dilemma against an opponent who employed reasoning above the subject's initially assessed state.

Examines the modifiability of children's information processing strategies by modeling techniques in fourth grade internally and externally oriented children. (LLK)

A matching task was presented to 120 subjects from 6 to 20 years of age to investigate the relative influence of dimensional salience and salience of variability on problem solving. The task included four dimensions: form, color, number, and position. (LLK)

Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

Observed 45 fourth- and fifth-grade boys and their parents in structured interaction situations. Boys selected for the study were highly internal and external in locus of control and were observed to assess the parental influence on their locus of control. (LLK)

Examines the concepts employed by normal and retarded children matched for mental age in kindergarten through fourth grades. Two studies explored the schema by which these children organized their experience into meaningful patterns. (LLK)

Investigates the effects of giving preschool children plans to resist distraction and their resistance in a subsequent work situation. (Author/LLK)

Studies the extent to which psychometric and Piagetian scales correlate during infancy and also explores the nomological networks of these scales and the degree to which their networks are similar. (LLK)

Investigated the separate and interactive effects of a model's affective response and anticipated consequences of third and fourth grade children's imitative and nonimitative play behaviors. (ED)
