SOME EFFECTS OF MORPHINE AND AMPHETAMINE ON INTELLECTUAL FUNCTIONS AND MOOD,
Abstract
The purpose of this investigation was to study the effects of morphine and d-amphetamine singly and in combination upon need, achievement, mood, and intellectual functioning. The Guilford factor analytic model of intellectual functioning, the Nowlis and Nowlis check list, and the McClelland need achievement scale were employed in measurement and interpretation. The Evaluation category of the Guilford model was the most sensitive to drug effects. Morphine enhanced performance on all tests in this category. The need to achieve and the sense of ''activation'' were increased by d-amphetamine. The other effects of d-amphetamine on intellectual functioning were irregular. The effects of the mixture of amphetamine and morphine could not be predicted knowing the effects of either alone. The Guilford model of intellectual functioning, the Nowlis and Nowlis adjective check list, and the McClelland need achievement scale all appear to be useful tools in the evaluation of psychoactive compounds upon human performance.
