Disfunctions are drawn between visual perception and visual function, and four optometrists respond with further analysis of the visual perception-visual function controversy and its implications for children with learning problems. (CL)

Two experiments were conducted to demonstrate that human infants 3 months of age perceive color in a normal, trichromatic manner. Results from these studies of the neutral zone and hue discrimination evidence trichromatic vision in infancy and are discussed in the context of their clinical, social, and intellectual implications.

Our need for constancy makes us classify people as well as objects. If a group of people accept our view of them and behave with consistency then we are comfortable dealing with them. In regard to racism, we tend to classify people in ways which act to lower their self concepts. (CJ)

This study of educable mental retardates and intellectually average children supported the commonsense notion that recognition skill is more highly developed than reproduction skill in same age children of both groups. (WY)

Tests the hypothesis that the Mueller-Lyer illusion will be less strong when an observer is distant from figures than when he is close, and presents results that do not confirm the hypothesis. (RW)

Findings showed no preference for the color white over the color black, contrary to previous studies. (Author/DLS)

Tested 18-month olds for mirror self-recognition using classic rouge test or an alternative procedure, for social contingency awareness by being closely imitated for a long time, and for capacity for communication by synchronic imitation. Results support hypothesis that self-recognition and spontaneous perspective-taking develop in close synchrony…

Experiments investigated whether more elements in the upper part of a visual configuration influenced newborns' preference for face-like patterns. Findings indicated that newborns preferred nonface-like stimuli with more upper part elements over nonface-like stimuli with more lower elements, but did not prefer face-like over nonface-like stimuli…

Investigated 5-month-olds' perception of an object whose center was occluded and whose ends were visible only in succession. Found that infants perceived the object as one connected whole when the ends underwent common motion but not when the ends were stationary. Results suggest that infants perceive object unity but not object form. (Author/BC)
