Abstract
Three groups, each containing eight rats on 23-h water deprivation, were trained in a straight alley runway. During acquisition, Group 1 received distilled water as a reinforcer, Group 2 a 4% sucrose solution, and Group 3 a 16% sucrose solution. Following acquisition, Ss received shock as they entered the goalbox. A derived measure of approach magnitude was obtained for 4 successive days of conflict testing. Significant differences were obtained on Day 1, indicating the magnitude of approach to be greater for those groups receiving a sugar solution as a reinforcer.
