Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER PEOPLE CAN CHANGE THEIR PERCEPTUAL PROCESSING STRATEGIES TO INCLUDE TESTS FOR THE PRESENCE OF ONLY THOSE STIMULUS FEATURES NECESSARY FOR THE TASK AT HAND. LEARNING DURING PRACTICE AND THE EFFECT OF AGE ON THE ABILITY TO USE OPTIMAL STRATEGIES WERE INVESTIGATED. A DISJUNCTIVE REACTION TIME PROCEDURE WAS…

BOTH COGNITIVELY-ORIENTED AND RESPONSE-ORIENTED THEORIES OF PERCEPTUAL LEARNING ARE DISCUSSED AND CONTRASTED WITH A STIMULUS-ORIENTED THEORY. PERCEPTUAL LEARNING IS DEFINED AS AN INCREASE IN SPECIFICITY OF DISCRIMINATION OF THE STIMULUS INPUT. THE AUTHOR DESCRIBED WHAT IS LEARNED IN PERCEPUTAL LEARNING AS () THE DISTINCTIVE FEATURES OF THINGS, (2)…

Additional support to a stimulus-response (S-R) association by the use of an extraneous stimulus is called "prompting." Prompting has an effect on learner achievement particularly if the prompting agent is identical on successive S-R trials. This experiment sought to analyze the differences in learner achievement when different prompting stimuli…

Trained preschoolers and adults on three sets of successive discriminations with stimuli labeled A, B, and R. Tested for derived stimulus-response relations and stimulus-stimulus relations. Adults displayed class-consistent B-R and A-B performances over all conditions. Children's display of class-consistent B-R performance varied by training…

Infants in four age groups--three, six, nine and twelve months--were exposed to an experimental procedure designed to assess the extent to which such subjects were capable of discriminating between different orientations of the same form, and the extent to which they were capable of recognizing the identity between different orientations of the…
