First, third, and fifth graders made judgments of the geographical slant of surfaces depicted in photographs while optical slant and postural orientation were manipulated. The results indicated the existence of a linear mechanism which compensates for the effect of postural inclination. (JMB)

The sensory modality of a task and the modality of a retroactive interfering activity were systematically covaried in order to test two models of intersensory functioning. Subjects were 40 ten-year-old boys and girls. (BD)

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)

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)

Analyzes third grade children's performance on the Mueller-Lyer Illusion for whole and partial presentations of the figure. Results do not support Piaget's theory of perceptual development but are consistent with the theory of simultaneous and successive syntheses. (Author/BH)

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)
