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)

Results indicate that seven-month-old infants are sensitive to the depth cues of linear perspective and texture gradients. Self-produced locomotor experience is not necessary for the development of sensitivity to static-monocular depth information. (RJC)

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)

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

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)

Examined how children's and adults' initial conceptions of objects and space influence predictions about the physical world, but lead the naive person to misconstrue a dynamic event. Found that participants proficiently anticipated where an oscillating screen would contact a hidden object, but underestimated the distance until contact.…

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

Analyzes the research strategies, stimuli, subjects, statistical strategies, and relative variables in 34 empirical studies on children's representation of three-dimensional objects. The studies fell into three categories: children's representation of spatial relationships within an object, between two objects, and studies that included both. (MJP)
