Perceptual Deprivation Tolerance and Adequacy of Defenses

Abstract

The Rorschach test was administered to 14 Ss who had endured a week of perceptual deprivation and to 7 Ss who had terminated isolation prematurely. An Index of Control, equivalent to the proportion of Defense Demand to Effectiveness of Defense, was derived for each S. Groups with High- and Mid-control Indices tended to be composed of successful Ss whereas the group with a Low-control Index tended to be composed of unsuccessful isolation Ss.
