Effects of laboratory-induced controllable and uncontrollable stress on Rorschach variables m and Y.

Abstract

The research literature regarding stress and the Rorschach has frequently produced contradictory results. A possible explanation for the lack of consensus may be that past research has failed to consider the nature of the stressor. A potentially important dimension is whether the stressor is perceived as controllable or uncontrollable, particularly because these two types of stressors invoke distinctive sets of biobehavioral reactions. We examined the effects of experimentally induced uncontrollable and controllable stress on m and Y Rorschach responses. Uncontrollable laboratory stress was associated with an increase in both m and Y variants, whereas controllable laboratory stress was associated with an increase only in m. Potential implications and directions for future research are discussed.
