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)

Two experiments were conducted investigating the extent to which transfer of training would take place. (Editor)

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

This paper presents further data on the Moss-Harlow Effect, together with some new theory, supporting the conclusion that younger subjects prefer novelty more than do older children. (Author)

Author attempted to relate research in the area of musical studies with Leon Kamin's research with animals. The experiment with human subjects set out to measure the presentation of auditory stimuli without punishment as an indication of memorization processes. (RK)

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)

Questions processes involved in physical matching task when stimuli are presented for duration short enough to prevent physical scanning. Research supported by U.S. Public Health Service. (DS)

Description of a study testing for retention of visual material identified as being familiar or unfamiliar to the subjects. (HB)

An attempt to isolate possible effects of the application of visual reminders on learning by TV. The underlying assumption was that learning by means of television and other visual media can be enhanced by methodically applying visual reminders. (Author)

Two major trends in the development of natural language concepts were found in the present study: (1) there was a clear indication that such concepts exist in a relatively fragmented form in young children; (2) young children showed a strong dependence on perceptual attributes in their definitions of concepts.
