Twenty-four congenitally visually handicapped infants, aged 6-24 months, participated in a study to determine (1) those stimuli best able to elicit visual attention, (2) the stability of visual acuity over time, and (3) the effects of binaural sensory aids on both visual attention and visual acuity. Ss were dichotomized into visually handicapped only and multihandicapped groups for purposes of analysis. Results indicated that visually handicapped only infants spent more time attending to stimuli, but no preference was shown by either handicapped group for type of stimulus or method of presentation. In addition, Ss improved on the visual acuity measure over an 8-week period, regardless of handicapped group or an 8-hour exposure to binaural sensory aids. Finally, a disordinal interaction occurred among binaural sensory aid, stimulus type, and handicapped group; and mere exposure to the binaural sensory aid without specific training was judged not to be effective in a program of visual efficiency training for infants 6-24 months old. Visual stimulation procedures as utilized with older visually handicapped children are questioned as applied to infants 6-24 months old. (Author)
