Amphetamine on Rorschach measures in normal subjects.

22 normal college men (mean age 20.3 yrs) were administered either dextro-amphetamine (0.2 or 0.4 mg/kg) or placebo in a double-blind, counterbalanced design to determined whether a single administration of amphetamine would increase indicators of state-related stress and anxiety and not elevate indicators of thought disorder. Test sessions were 3 wks apart and included, among other measures, the Rorschach test. Rorschach anxiety and thought disorder variables were measured under drug and placebo conditions. Results suggest that amphetamine causes an increase in Rorschach anxiety indices but does not elevate Rorschach indices of thought disorder. The observed dissociation of anxiety and thought disorder on the Rorschach has implications for the role of the Rorschach in studying neurobiological correlates of acute stress and anxiety.
