Abstract : The experiment was designed to measure four component effects of d-amphetamine in a paired-associate learning task. The drug was compared with placebo to reveal (1) effects upon acquisition of new material, (2) persistence of material so learned, (3) effects of drug present during test of delayed recall, and (4) interactions between drug present during learning and drug present during test of delayed recall. Paired associates of varying degrees of usage frequency, association value, and intra-list competition were employed. Sixty-nine college males were tested in two sessions, for learning and delayed recall respectively. Presence of the drug during learning resulted in significantly greater delayed recall of the low-competition lists, and non-significantly greater delayed recall of high competition lists. The same dosage given for the recall session had no significant effect upon delayed recall or relearning. (Author)
