Presents nine experimental studies investigating auditory and visual discrimination in very young infants. Results are discussed in terms of their implications for understanding habituation, cross-modal stimulation, receptive language development, and individual differences. Appendices include data on visual fixation duration and information on…

Seventeen preschool children were administered two color-discrimination pretests, verbal and nonverbal. The five children who scored lowest were chosen to recieve the color program. Four scored elow 85 percent on the nonverbal pretest, whereas the other 12 children scored above 85 percent. On the verbal pretest, all five experimental subjects…

A study tested a multiple-resources model of human information processing wherein the two cerebral hemispheres are assumed to have separate, limited-capacity pools of undifferentiated resources. The subjects were five right-handed males who had demonstrated right visual field-left hemisphere (RVF-LH) superiority for processing a centrally…

This study investigated the response behavior of nine infants, aged 13-15 weeks, to a recurrent pattern of visual and verbal stimuli presented by their own mothers and by female strangers. The infants were presented with the following 2-minute sequence (repeated 3 times): (1) one-half minute of an unknown female leaning over the crib with a…

Three projects were designed to develop and evaluate materials for use with aphasic children (perceptually handicapped with language problems). The first project presented stimulus pairs in varying modality conditions. Results suggested that, although the aphasic children were not capable of improving their auditory discrimination performance,…
