Three groups of Nigerian high school and college students were tested for response to four pictorial depth cues. Students had more difficulty with cues concerning the relative size of objects and the foreshortening of straight lines than with cues involving overlap of lines and distortion of the angles between lines.

Investigates the responsiveness of 14- and 20-week-old infants to binocular information using a stereoscopic shadow caster showing an object approaching on a collision course. (Author/SS)

A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and…

A visually directed sensory motor training program with a 30-day duration did not enhance the depth perception of five-year-old children. (MM)

A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

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)

Results of two studies were consistent with the view that 3-month-old infants perceive movement in depth during their own movement. They can move to avoid a surface just prior to contacting it. (Author/RH)

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 the design of visual simulation equipment for training systems, one key decision is the nature of the image storage medium to be used. One consideration in this complex issue is the adequacy of the depth cues which can be derived from imagery based on two- rather than three-dimensional sources. Although motion parallax is a relatively minor…

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)
