Abstract:

Callaway and Stone have proposed that drugs which arouse or depress the electroencephalographic response should differentially affect the re-ACTION TO STIMULI WHICH OCCUR WITH DIFFERENT FREQUENCIES. The object of this study was to test this hypothesis. The disjunctive reaction times to stimuli with different probabilities of occurrence were obtained from Ss while under the effects of chloropromazine, d-amphetamine, atropine, and sucrose. The data demonstrated that Ss RT is a function of the probabilities of the stimuli, that chloropromazine increases RT and that amphetamine decreases RT. There was no evid nce to support the hypothesis of a differential drug effect on stimuli with different probabilities of occurrence. Author
