The effects of d-amphetamine on the inter-response times of rats and guinea-pigs on a modified Sidman discriminated avoidance schedule
Tóm tắt
Four rats and four guinea-pigs were trained under a modified Sidman discriminated bar-bress avoidance schedule. The guinea-pigs acquired the avoidance response more rapidly than the rats. The Bovet-Gatti d-amphetamine profiles were similar in both species in that there was a significant increase in responding before the stimulus light and click were presented and the inter-response times of efficient responses were shorter. The data indicated that guinea-pigs may be better subjects for psychopharmacological work involving discriminated bar-press avoidance behavior.
