DRUG EFFECTS UPON PERFORMANCE UNDER TASK-INDUCED STRESS.

Abstract

An experiment was performed to test the interaction between drug/placebo effects and incentive conditions under task-induced stress. Sixty-three student volunteers served in a factorially designed experiment varying level of incentive, drug condition, and placebo condition (whether or not the subject was led to believe he had received a drug). All active drugs were given in disguised form. These included d-amphetamine sulfate (10 mg.), CHLORDIAZEPOXIDE HCL (10 mg.), and methylphenidate HCL (10 mg.). Neither the incentive nor the 'placebo condition' factor had a significant effect upon performance. D-amphetamine showed a significant superiority to other drug conditions early in the session. Most of this superiority derived from the ''high stress'' condition. Mood effects were also noted. Results were interpreted as favoring a mood-related component in performance enhancement rather than the psychoanalytic factor. (Author)
