Abstract
The impact of familial deprivation on the acquisition of skill for pictorial depth perception was studied on two groups of 125 children each from Indian nurseries and orphanages, ranging in age from 3 to 61/2 years. Ss were required to judge distance by interpreting each of the six common pictorial cues depicted one at a time in a set of pictures. Analysis of mean scores revealed a clear developmental trend in both the groups. Intelligence was significantly correlated with the scores. With intelligence controlled, significant retarding effects of deprivation on the scores at the higher age levels but none at 3 to 4 years were found. Comparison of scores on each of the six cues revealed the same tendency. Lack of heterogeneity and absence of stimulation in orphanages had a general retarding influence on the development of the skill for pictorial depth perception.
