The relation between Matching Familiar Figures Test performance and Piaget's construct of perceptual activity was examined with 48 third- and fourth-grade boys. (SB)

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

The importance of awareness of the pictorial surface and point of observation was investigated in children and adults. The effect of station point was found to interact with pictorial surface and age, thus suggesting the development of a mechanism of compensation for the perspective distortion of oblique view. (JMB)

The effects of perceptual and cognitive factors on information processing in visual periphery were studied in 5- and 8-year-old children and in adults. Subjects judged either the similarity (Study 1) or identity (Study 2) of geometric forms. (Author/SB)

Visual pattern preferences were established for 96 9- and 13-week-old infants using stimuli varying in contour density presented either at a low, moderate, or high luminance level. Age differences in the maximally preferred patterns across stimuli and luminance levels indicated that luminance interacts with contour density in determining stimulus…

Subjects aged 8, 10, 12, and 18 years participated in two visual search tasks. (Author/SB)

Two studies explored the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both experiments, kindergarten, second- and fifth-grade children were required to classify sets of stimuli that varied in size and brightness. (SB)

Reports two experiments which examined developmental changes in the patterns of preference for varying degrees of perspective while controlling for the station point used in viewing. Subjects were 28 preschool children (age four years), 23 elementary school students (age six years) and 30 college students from introductory psychology classes. (MP)

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

A visual search task was used to assess developmental changes in elementary school children's selective attention to specified portions of a visual display. (Author/SB)

Preschool and third grade children matched the orientation of stimuli tachistoscopically presented at times individually set to achieve about 75 percent correct performance. Preschoolers showed no superiority on left versus right while third graders showed significant top and right superiorities. Results are compared with those for adults on the…

Three experiments were performed using an aperture-viewing technique to assess the accuracy of shape perception when subjects were required to emit eye movements in order to pick up shape information, compared with the accuracy of shape perception when subjects were not required to emit eye movements. All three experiments explored whether the…

Presents a study of perspective taking ability among children aged 3 to 7. The first task involved a classic block appearance task. In the second task, the child and/or the experimenter each wore different colored glasses and the child was asked to describe how a white card appeared to each of them. (BD)
