Investigates the different levels in the visual system at which laterality effects may be elicited in children and adults in five different experiments. (LLK)

Children and adults performed a divided attention task and two selective attention tasks with shapes that were either spatially integrated or separated. Results indicate that integrated stimuli are initially perceived as wholes, and separated stimuli as features, at all ages. (BC)

Results varied as a function of : (1) type of task (transfer, paired associate, or visual discrimination); (2) student age (kindergarten, first grade, or college); (3) stimuli size; and (4) number of response indicators. Research findings cannot be generalized from artificial orthographies to the English alphabet or from various aged subjects to…

Described are three experiments which probed children's sensitivity to structure or organization in visual patterns. Each experiment employed a different paradigm (complexity judgment, discrimination learning, recognition learning, and memory) in order to tap different aspects of children's use of structural information. Subjects were children in…

The few studies concentrating on adult age changes in discrimination shift behavior have reported that the performance of elderly adults on such tasks is inferior to that of younger adults and, in fact, similar to that of children. To determine whether verbal labeling, which has facilitated the performance of young children, would also reduce age…
