This study investigated developmental memory capacity through picture span and feature binding. Participants included third grade students and college age adults with typical development. Picture span was used to assess working memory capacity when participants were asked to identify, locate, and sequence common visual-graphic symbols from…

To act and think, children and adults are continually required to ignore irrelevant visual information to focus on task-relevant items. As real-world visual information is organized into structures, we designed a feature visual search task containing 3-level hierarchical stimuli (i.e., local shapes that constituted intermediate shapes that formed…

Presents two experiments which investigated whether there is a shift with age in the relative speed and difficulty of same versus different judgments. Subjects included preschoolers, third graders, and college students. (SDH)

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

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…
