title: Marijuana-induced primary process content in the TAT.
abstract: Seventy-two normal adult male subjects wrote TAT stories under baseline and either placebo- or marijuana-ingestion conditions. Marijuana subjects received 20 mg. doses of delta-9 tetrahydrocannabinol. The stories were keypunched and content analyzed with the Regressive Imagery Dictionary, which yields a score for primary process content. Results indicate that marijuana, relative to placebo, caused subjects to write stories with a higher proportion of primary process content than they had included in baseline stories.
