Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…

Two experiments examine the sorts of cues that might be available to facilitate children's ability to discriminate between memories for their own actions. Results suggest that the differences in discrimination performance demonstrate the importance of kinesthetic cues and visible consequences for children's memory discrimination. (Author/RWB)

Examines the importance of (1) dimensional characteristics of stimuli present in discrimination transfer tasks, (2) having contrasting stimuli presented simultaneously, and (3) subjects age. Subjects were rural Mexican youths, ages 4 to 10. Reversal and nonreversal type discrimination transfer problems were used in the study. (DP)

Second grade Ss and college students were tested under three conditions of the temporal relationship of feedback and stimulus information. (Editor)

This study was designed to investigate the interacting effects of dimensional pre-training and set size on acquisition of a multiple discrimination involving letters of the alphabet. (Author)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli.

Reports research demonstrating that fourth-grade subjects could not solve a basic transverse patterning problem involving pairs of geometric forms even after 90 trials. The addition of one nonspatial dimension, however, resulted in solution. Also, the greater the number of nonspatial dimensions present, the better the learning. (Author/SDH)

This study examines serial habituation in a sample of 54 infants aged 2, 3, and 4 months to determine whether age changes are partially a function of different "strategies" rather than simply different rates of habituation. The serial habituation hypothesis proposes that attention and habituation of attention proceed in order of the relative…

Four studies with infants and preschool-age children examined various pattern perception tasks considered to be related to the perceptual basis of the development of reading skills. Study 1 used 28 neonates to test the hypothesis that supplemental stimulation (rocking, patting, holding) has measurable effects upon attention to visual patterns.…

This study was designed to assess the relative effectiveness of four components of pretraining on a subsequent simultaneous discrimination and reversal: (1) making same-different judgments about the two stimuli; (2) making a specific observing response to the critical feature of the stimuli; (3) simple familiarization with the stimuli; and (4)…

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…

Finding suggests that in perceptual learning situations like that of the present study, there may be no particular advantage to impoverishing the environment'' by minimizing irrelevant cues, at least as far as the children's immediate memory for stimuli is concerned. (Author)
