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.

Since the adoption by the American Psychological Association (APA) in 1995 of an offi cial policy endorsing state legislation that would authorize appropriately qualifi ed psychologists to prescribe psychotropic medication (DeLeon, 1996), an increasing number of states have seen the introduction of such legislation. In 1998, the Territory of Guam became the fi rst jurisdiction to enact prescriptive authority legislation for psychologists. Despite fi erce opposition from organized medicine, especially from the psychiatric community, steady progress toward the goal has been made (Thomas, 2000). States such as California, Louisiana, Hawaii, and Georgia have been among the early leaders in the prescriptive authority initiative, and the list of states that have already introduced legislation or are preparing to do so is growing year by year (Jennings, 2001).In the spring of 2001, the New Mexico legislature considered a bill that was introduced with broad-based support on behalf of the New Mexico Psychological Association (NMPA). The bill advanced through committees of jurisdiction in both houses and passed the House, only to die on the fl oor of the Senate without ever coming to a vote in that chamber (Foxhall, 2001). The near success of the NMPA-sponsored bill in the fi rst year of introduction
