Three experiments examined vision's role in infants' grasping of horizontally and vertically oriented rods. Found that infants differentially oriented their hand regardless of lighting and similar to control conditions where they could see rod and hand throughout reach. Findings suggest that infants may use current sight of object's orientation or…

Configural visual abilities in thirteen children with Williams syndrome (WS) compared to 13 children matched on mental age and 13 children matched on chronological age. Configural abilities were tested through four tasks (1) Silhouette (2) Fragmented (3) Mooney and (4) overlapping figures. In the first three tasks, it was necessary to take into…

The basis of young children's performance of judgments of recency and frequency was investigated using a modified version of Huppert and Piercy's [Huppert, F. A., & Piercy, M. (1978). The role of trace strength in recency and frequency judgements by amnesic and control subjects. Quarterly Journal of Experimental Psychology, 30, 347-354]…

The effects of gaze direction on memory for faces were studied in children from three different age groups (6-7, 8-9, and 10-11 years old) using a computerized version of a task devised by Hood, Macrae, Cole-Davies and Dias (2003). Participants were presented with a sequence of faces in an encoding phase, and were then required to judge which…

The relationship between hyperactivity and neuropsychological test performance at different age levels was investigated with 90 children 6-8 years old and 92 children 9-12 years old. Subjects were administered a battery of neuropsychological tests, and a parent completed the Child Behavior Checklist (CBC). Young children demonstrated no…

Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…

The effects of age, task, and egocentric responding on visual-spatial perspective taking were studied among 41 preschool children between 3.0 and 5.9 years of age. Children were individually administered three perspective-taking measures: the upside-down/right-side-up task, a block task, and a picture box task, all previously described in the…

A total of 100 third and ninth grade students participated in a study to determine how children of different ages perceptually segment a continuing behavior sequence presented on a television program. The children were shown a short segment from a motion picture on a videotape viewer. Following the viewing, the children completed unitizing…

The prediction that children would have more difficulty learning to differentiate faces of another race than their own, even though objective differences were constant, was tested. A discrimination task, consisting of two schematic drawings of faces cut from varying shades of brown (Caucasian), pink-tan (Negro) and green (control), and a doll…

This study uses a search task to investigate the development of word superiority effects in visual perception. Subjects are kindergarten, second and fourth grade children, and college students. (CM)

English-speaking and Dutch-speaking children were asked to pick the big, tall, or long members of pairs of bricks. Comprehension improved with age but older children in both groups were prone to choose the taller (but smaller) of two objects when asked to point to the bigger one. (SED)

Finding suggests that in perceptual learning situations like that of the present study, there may be no particular advantage to impoverishing the environment'' by minimizing irrelevant cues, at least as far as the children's immediate memory for stimuli is concerned. (Author)

One question prompting the present research concerned the relation between performance under tachistoscopic'' conditions where exposure durations are too brief to permit active overt visual search, and performance when overt search is possible. (Author)

Test Battery was designed to explore the auditory and the visual perceptual processing abilities of children from five through eight. (Authors)
