Examines the effect of different training methods on perceptual learning of impulsive children. A matching to sample method (M), and a differentiation method (D) were used. Data indicated that Ss receiving D training learned to process features distinguishing stimuli; whereas, Ss receiving M training showed no preference for a particular mode of…

Suggests that the information integration processes used by adults to form judgments are also used by children. (ST)

Findings provide information about developmental differences in sorting and recall, as well as evidence that organizational training may influence recall performance. (Authors)

Study examined the effects of an integrative or central information processing variable on visual-motor task performance of normal and mentally retarded Ss. (Authors)

It was concluded that developmental differences in focusing are related to developmental differences in reflection-impulsivity. (Author)
