Summary
Conflict behavior was induced in rats by simultaneously rewarding with liquid food and punishing with pain shock every lever response made in the presence of a tone. Meprobamate, phenobarbital and pentobarbital increased the number of shocks a rat would accept in order to obtain the food reward; in contrast, promazine and d-amphetamine decreased the number of shocks taken. The technique thus permits a separation on a behavioral basis of meprobamate, pentobarbital and phenobarbital from promazine and d-amphetamine.
