Abstract

Fourteen female albino rats served as Ss in a test of the theory of signal detectability. Motivation was controlled by maintaining Ss at 80% ad lib body weight. Four pilot Ss were first placed in a detection task receiving reinforcement for hits and correct rejections and shock for misses and false alarms. Experimental Ss were placed in a shuttle box with food at one end. Ss had to cross an electrified portion of the floor to reach the reinforcement. One group received reinforcement for hits and correct rejections and shock for misses and false alarms. The other group received reinforcement for hits and correct rejections, shock for misses and no reinforcement-no-shock for false alarms.
