Children drew pictures of two objects placed in side-by-side or end-to-end views. Objects faced forward, backward, right, or left in such a way that one object occluded the other in some views. Children produced fewer drawings depicting occlusions for end-to-end than for side-by-side alignments. (BC)

A developmental study of the relation between apparent size and pictorial depth demonstrated the usefulness of operant techniques in establishing equivalent differential responding and interesting stimulus equivalence in adults, 9- and 3-year-olds. (Author/AJ)

In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. (Author/SB)

This study was designed to investigate the development of the visual placing response in infants, as well as the visual mediation of the response and texture factors that influence this response during its development. The response was associated with age and apparently developed in two phases. (Author/DB)

Ninety-seven children between 5 and 8 years of age drew two arrays, four times each, in different orientations vis-a-vis the child. Younger children's drawings contained much array-specific information but often no indication at all of the child's viewing position. Older children's drawings were predominantly view-specific, often containing little…

Had children draw two blocks arranged in depth, and then moved either child or array and had children draw what was then a left-right arrangement; the transformation was then reversed for a final drawing. Found that when children moved to a new standpoint, there was a significant increase in vertical portrayal (as depth portrayal) between first…

In this experiment, 446 children, ranging in age from 5-10 years, were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded to the nearer. (MS)

Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

Results of this study suggest that 3-year-olds have a good deal of sensitivity to static depth information. (Authors)

Tests the hypothesis that children will be better than adults at perceiving depth at large disparities in random-dot stereograms. Subjects were 4, 6, 8, and 25 years of age, with six males and six females in each of the four age groups. (MP)

Reports two experiments in which plain blocks of various sizes were presented in various spatial orientations to children three-eight years old in an attempt to establish how they represent three-dimensional spatial relations pictorially. Results showed that young children represented depth in the array vertically in the picture plane. (RH)

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Young children drew two opaque objects placed one behind the other. Over two-thirds of the children drew the objects separately in horizontal or vertical relationships. When drawing an object in a glass beaker, half of the children depicted the object vertically or horizontally separate from the beaker. (Author/DB)

Six motion projections were presented to first graders, seventh graders, and college students (N=72) in order to determine whether children can utilize the same motion parallax information as can adults. (MP)
