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)

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…

The authors have been engaged in research focused on students' depth of learning as well as teachers' efforts to foster deep learning. Findings from a study examining the teaching practices and student learning outcomes of sixty-four teachers in seventeen different states (Smith et al. 2005) indicated that most of the learning in these classrooms…

Pictorial depth perception of Tanzanian children was investigated using two versions of Hudson's pictures test. Revised version test scores were higher for all children. (ST)

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)

Several investigations have shown that young infants perceive the unity of a center-occluded object when the visible ends of the object undergo common motion but not when the object remains stationary. This study is an extension of earlier investigations on object unity in that it assesses amodal completion of stationary circles in which one half…
