Purpose of the present experiment was to compare performance of four- and six-year-olds on a conjunctive concept task in which the two relevant values were either within a single dimension (unidimensional) or from two different dimensions (bidimensional). (Authors)

Major finding was that punishment presented in the same sensory modality as the reinforcement was superior to punishment presented in a different sensory modality from the reinforcement. (Author)

Data were interpreted as suggesting that incidental learning may not be cumulative over trials, but rather, may be due to memory of the last trial. (Author)

Kindergarten children were given simultaneous discrimination tasks with two irrelevant dimensions varying within settings. Prior to each block of feedback trials, the children were asked to provide a statement of the solution. The trial block on which the correct relevant dimension was first verbalized was found to be predictive of discrimination…

Two groups of mentally retarded children (MA: 4 to 8 years) were pretrained using two different methods. It was predicted that shift performance of the two groups trained to use different strategies would resemble those of two different developmental levels. (MP)

Results imply that sets of instructions may form a response class, with characteristics similar to those found in studies of generalized imitation. (Author)

Studies based on an analysis of one species of learning and transfer task, the transposition problem, in terms of two ways in which the experimenter's and the child's definition may differ. (Author)

Predictions for multidimensional generalization were derived from Hull-Spence learning theory, and an experiment is reported that was designed to test this aspect of the theory. Alternative to this analysis is presented in PS 502 062; authors respond in PS 502 063. (Authors/MB)
