Further Study of Interactive Effects of Amphetamine and Food Deprivation

Abstract

64 male Holtzman rats were randomly assigned to 16 independent amphetamine and food deprivation conditions to determine the interaction effects of the conditions on food consumption and contact time with the food dish. The results demonstrated a significant interaction effect of amphetamine and food deprivation on food consumption ( p < .05) and on contact time ( p < .01). The results were discussed in relation to previous findings of such an interaction effect, and it was concluded that the phenomenon demonstrates a considerable amount of generality.
