Tests the hypothesis that children will be better than adults at perceiving depth at large disparities in random-dot stereograms. Subjects were 4, 6, 8, and 25 years of age, with six males and six females in each of the four age groups. (MP)

Discusses changes occurring in two-, four-, and six-month-old infants' visual attention span, through a series of experiments examining their ability to orient to peripheral visual stimuli. The results obtained were consistent with the hypothesis that infants get faster with age in shifting attention to a spatial location. (AA)

Infants between four and eight months of age were tested for their ability to reach for visible and unseen toys that made sounds. Infants reached for toys in the dark under two auditory illusion conditions, the Haas effect and the midline illusion. Results indicated that, by four months of age, infants perceived the Haas effect and the midline…

The capacity of six-month-old infants to maintain information in working memory for several seconds was studied using two versions of an oculomotor delayed response task. The results indicated that infants maintained information about stimulus locations in working memory for three to five seconds. (MDM)

The development of visual orienting to a cued target on the part of practicing and nonpracticing tennis players aged 13, 16, and 25 years was examined. Results indicated that practicers were not faster than nonpracticers in processing visual information and that subjects of all ages oriented attention voluntarily to cued locations. (LB)

Results support the contention that with advancing years brain-damaged children may adapt to and/or recover from the deficit(s) involved in the inability to develop and maintain a readiness to respond. (Author/MB)

Event-related potentials (ERPs) of children and adults were measured while subjects observed pictures of facial expressions. Adults had greater ERP responses to happy than to angry faces, whereas children had greater ERP responses to angry than to happy faces. (BC)

Tested infants' latency in turning toward stimulus patterns and the duration of their initial fixation. Results showed that "turning latency" fell in a linear manner from 36 to 120 weeks after conception. Fixation time fell abruptly at 53 weeks. Preterm and full-term infants showed the same developmental trends. (BC)

Results from three studies involving college, third grade, and kindergarten subjects, suggest that individuals across a wide age range are able to use the visual properties of a stimulus for only a very brief period as the basis for making matched judgments. (Author/SDH)

Reports on a series of four experiments designed to determine more precisely the characteristics of the stage of visual feature analysis of word identification and to examine response competition factors in this interference task. (SB)

Older children had faster reaction times overall than did the younger children, and the difference between reaction times in the two experimental conditions was greater for the older children than for the younger children. (Authors/MB)

Covert visual orienting was measured in 13 twelve-year-old and 11 fifteen-year-old hockey players and in 13 college students with no hockey training. Found that high-skill 15-year-olds were better able than all other groups to take advantage of the general alerting effect produced by the sudden onset of a cue. (MDM)

The reaction times, movement times, and final accuracy of hand movements of 6, 8, and 10 year olds that were directed toward visual goals were measured by means of tasks in which direction and amplitude components of movement were required. (RH)

Three experiments obtained same-different judgments from children and adults to trace normal development of local and global processing of hierarchical visual forms. Findings indicated that reaction time was faster on global trials than local trials; bias was stronger in children and diminished to adult levels between ages 10 and 14. Reaction time…
