Resumo
The effects of d‐amphetamine and pentobarbital were studied on performance during 3‐hr sessions under fixed‐interval 60‐min schedules of food presentation. Low doses of d‐amphetamine increased rates of responding and higher doses decreased rates of responding, both during the entire 3‐hr session and during each of the individual fixed intervals. Pentobarbital produced little effect on rates of responding averaged over the 3‐hr session, but it decreased rates during the first fixed interval and increased them during the second and third fixed intervals. The effects of d‐amphetamine were shown to be dependent on the control rate of responding, as has been shown with shorter fixed‐interval values. Analysis of d‐amphetamine effects in terms of the point at which the probability of responding is greater than zero was not descriptive of overall fixed‐interval performance.
