In Experiment 1, we trained four pigeons to concurrently discriminate displays of 16 same icons (16S) from displays of 16 different icons (16D) as well as between displays of same icons (16S) from displays that contained 15 same icons and one different icon (15S:1D). The birds rapidly learned to discriminate 16S vs. 16D displays, but they failed…

Following pretraining on three figures, 44 nonhandicapped preschoolers were assigned to experimental groups to investigate methods of integrating a new, similar symbol into a set of familiar symbols to approximate the difficult disciminations encountered by young children in school. (Author)

Infants ranging in age from six months to eight months were shown repeated instances of real object movement-disappearance-reappearance. Results suggest that the key changes in early cognitive development rest primarily upon the infant's gradual adaptation of old responses through encounters with new events--rather than upon the acquisition of…

Four experiments investigated newborns' ability to discriminate, recognize, and learn visual information embedded in the schematic face-like patterns preferred at birth. Results indicated that newborns discriminated face-like stimuli relying on their internal features and recognized a perceptual invariance between face-like configurations in…

CONCEPT FORMATION IN 50 KINDERGARTENERS WAS STUDIED BY REQUIRING THE CHILDREN TO SORT CARDS ACCORDING TO ONE OF FOUR ATTRIBUTES OF THREE DIFFERENT DIMENSIONS. THE OBJECTIVE WAS TO EXPLORE THE VALIDITY AND LIMITATIONS OF AN ALL-OR-NONE LEARNING MODEL FOR COMPLEX CLASSIFYING RESPONSES. INFORMATION WAS PRESENTED TO THE SUBJECT BY TWO POSITIVE…

This study established a controlled instructional procedure for visual concept learning in a school setting and investigated the possibility that an ability trait difference could affect visual learning of the concept. A total of 84 high visualizers and 84 low visualizers were selected from 629 fourth grade children according to their scores on…
