Abstract
Pairs of rats were injected with adrenalin, placebo, or chlorpromazine and allowed to interact freely in an open field. Adrenalin-injected rats were significantly more sociable than placebo rats, who in turn were more sociable than chlorpromazine. On later test trials, all animals received placebo injections. There were no differences among conditions, suggesting no residual effects of drugs or of drug-induced experiences in the field.
