Hearing-impaired 6- to 13-year-olds (N=24), trained to discriminate between two stimulus complexes differing in shape, direction, and number, were asked to discriminate between individual characteristics in all possible pair combinations. General failure to respond to all characteristics equally suggested that hearing-impaired children tend to be…

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)…

Article describes an experiment showing through paired associate testing how different groups can have the same total learning time. (Author/MM)

Examines the interrelationships of task performances and developmental changes of 4-, 6-, and 8-year-olds. Significant developmental changes were observed on transposition, cue interference, and spatial memory. The pattern of intercorrelations between tasks suggested a high degree of correspondence across tasks. (ST)

Discrimination learning set performance was examined in preschool children as a function of age and number of trials per problem. Subjects were 120 children three, four, five, and six years old. (MP)

Describes observer-based technique for assessing auditory capacities of infants from three to 12 months of age. This technique, referred to as the Observation-based Psychoacoustic Procedure (OPP), combines features of the Forced-choice Preferential Looking Technique and of the Visual Reinforcement Audiometry. Pure-tone detection and frequency…

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…

Evaluates the efficacy of two training procedures for eliminating selective stimulus control observed with three trainable mentally retarded children. In another experiment, improvements in stimulus control were not a function of varying degrees of difficulty between stimulus sets or of a prior history of discrimination training with the less…

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…

When 112 fifth- and sixth-graders were observed for their use of one of two possible rehearsal strategies in verbal discrimination learning tasks, the strategy in which the children generated a functional explanation of the word showed a positive influence on simple frequency discriminations. Data analyses also indicate that under this strategy…

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…

The research concerned the association of neutral objects, such as nonsense syllables, with rewards, such as money and candy, in children. Thirty-six subjects were obtained from grades two through six of local public elementary schools in Nashville, Tennessee. Associations between neutral objects and rewards were formed in a task concerning…
