Perception of hostility in the TAT as a function of defensive style.

Groups of male and female students with high, intermediate, and low scores on Byrne's Scale of Repression-Sensitization judged the amount of hostility and the darkness of 10 TAT cards, including the blank. The groups' judgments for each card were expressed in terms of the statistic E, a non-parametric index of discriminability derived on the basis of the theory of signal detection. Subjects with low scores on the scale showed significantly lower E values for hostility (p less than .05), but not for darkness, than the other two groups. It was concluded that differences in sensitivity to affective stimulation underlie the dimension of Repression-Sensitization.
