Amphetamine increased anxiety scores on the Rorschach test in healthy men but did not affect thought disorder measures. This dissociation suggests the Rorschach may differentially assess anxiety and thought disorders.

Area of Science:

  • Psychopharmacology
  • Clinical Psychology
  • Neuroscience

Background:

  • The Rorschach test is a projective psychological test used to assess personality characteristics and emotional functioning.
  • Understanding the effects of stimulant medications like amphetamine on psychological measures is crucial for clinical and research applications.

Purpose of the Study:

  • To investigate the effects of d-amphetamine on Rorschach anxiety and thought disorder indices in healthy male undergraduates.
  • To examine the dissociation between anxiety and thought disorder responses under amphetamine administration.

Main Methods:

  • A double-blind, counterbalanced design was employed with 22 healthy male undergraduate participants.
  • Participants received either d-amphetamine (0.2 mg/kg or 0.4 mg/kg) or a placebo across test sessions spaced three weeks apart.

  • Rorschach test performance was assessed for anxiety and thought disorder variables under each condition.

    • Main Results:

    • D-amphetamine administration led to a significant increase in Rorschach anxiety indices.
    • No significant elevation in Rorschach indices of thought disorder was observed following amphetamine administration.
    • A dissociation was noted between the drug's effects on anxiety versus thought disorder measures.

    Conclusions:

    • The findings suggest that amphetamine specifically enhances anxiety-related responses on the Rorschach without impacting thought disorder indicators.
    • This dissociation has implications for the utility of the Rorschach in differentiating between anxiety disorders and thought disorders, such as schizophrenia.
