IN A REPRODUCTION TASK WHICH INCLUDED INSTANCES OF SEVERAL SCHEMATA MIXED TOGETHER, SUBJECTS LEARNED TO DISTINGUISH AMONG THE SCHEMATA WITHOUT KNOWLEDGE OF RESULTS. A BEST FITTING EQUATION DESCRIBING PERFORMANCE AS A FUNCTION OF NUMBER OF REPRODUCTION TRIALS ACCURATELY PREDICTED LEARNING WITH NEW SUBJECTS AND PATTERNS RANDOMLY SAMPLED FROM A…

The relationship between conceptual complexity and stimulus saliency was explored in a 3 x 4 factorial design using 144 undergraduates. Levels of complexity were represented by varying the ratio of relevant-to-irrelevant dimensions (1:3, 2:2, and 3:1). The saliency factor varied according to the discriminability between each attribute within…

A two-phased training study attempted (1) to accelerate the rate at which a total of 8 severely and profoundly retarded children (mean age 57 months) developed the Piagetian concept of object permanence and (2) to demonstrate generalization of the higher performance on object permanence scale to other scales of sensorimotor intelligence and to the…
