Effect of Chlorpromazine Hydrochloride on Maze Learning in the Guppy

Abstract

Kellogg and Gavin (1960) demonstrated that guppies could learn mazes quite readily. Earlier, Cutting, et al. (1959) found that drugs affect the CNS in fish, including guppies, in much the same manner as in other lower animals. In this study the effects of a tranquilizer drug, chlorpromazine hydrochloride, on the learning of guppies in a non-avoidance sinlation was studied. N o attempt was made to assess the physiological effects involved.Method.-Ss were 10 guppies ( 1 to 1% in. long), 5 in each of 2 groups.
