    A parametric description of amphetamine's effect on response rate: changes in reinforcement efficacy and response topography (1985)

    Notes: Abstract A mathematical model was used to describe the effects of amphetamine on the rate of a reinforced response in the rat. The model provides measures of reinforcement efficacy and response topography for behavior maintained by variable-interval reinforcement schedules. In this study the measured behavior was a lever press, the reinforcer was water, and the variable-interval schedules provided five different rates of reinforcement, ranging from about 20 to 660/h. In each session the rats were exposed to each of the five schedules, and as reinforcement rate increased, the rate of lever pressing increased in a negatively accelerated manner that was closely approximated by the equation for a rectangular hyperbola. Amphetamine changed responser rate and the parameters of the best-fitting hyperbolas. The 0.25–1.0-mg/kg doses increased response rate, and the parameter changes supported the interpretation that the increases were due primarily to an increase in reinforcement efficacy. The 2.0- and 3.0-mg/kg doses decreased response rates maintained by low reinforcement rates and increased response rates maintained by high reinforcement rates, and the parameter changes supported the interpretation that at higher doses amphetamine produced counteracting changes in reinforcement efficacy and response topography: reinforcement efficacy decreased, whereas response topography changed so as to increase response rates.

    Chlorpromazine and pimozide alter reinforcement efficacy and motor performance (1986)

    Notes: Abstract This study evaluated the effects of chlorpromazine and pimozide on reinforced responding. In each session, rats were exposed to a series of five variable-interval reinforcement schedules. The response requirement was a lever press, the reward was a small portion of water, and the reinforcement rate varied from about 20 to 660 reinforcers per hour. Response rate was a negatively accelerated function of reinforcement rate, and the relationship between the two variables was described by the equation for a rectangular hyperbola (the matching law). One parameter of the hyperbola is equivalent to the asymptotic response rate and the other parameter is equivalent to the rate of reinforcement that maintains a one-half asymptotic response rate. Chlorpromazine (0.75–3.0 mg/kg) and pimozide (0.1–0.4 mg/kg) dose-dependently decreased response rates. At low doses, the response rate decreases were, for the most part, restricted to the low reinforcement rate schedules. In contrast, the highest dose tested decreased response rates at both low and high reinforcement rates. The patterns of response rate decreases resulted in dose-dependent changes in the parameters of the matching law equation. The shifts in the matching law parameters were discussed in terms of the motoric and motivational interpretations of neuroleptic-induced response rate changes.

    Amphetamine analogs have differential effects on DRL 36-s schedule performance (1995)

    Notes: Abstract Amphetamine and related compounds have previously been shown to differentially release dopamine (DA) and serotonin (5HT) in vivo and in vitro. The purpose of this report is directly to compare five amphetamine analogs on differential reinforcement of low rate 36-s (DRL 36-s) schedule performance, and to determine whether the reported increases in dopamine and/or serotonin release induced by these drugs can be related to observed behavioral differences. Amphetamine (AMPH) and methamphetamine (METH) induced large increases in response rate, methylene-dioxymethamphetamine (MDMA) and para-chloroamphetamine (PCA) caused small increases in response rate, while fenfluramine (FEN) had no effect on response rate. AMPH, METH, PCA and MDMA caused a dose-dependent decrease in reinforcement rate, and FEN had no effect on reinforcement rate. AMPH, METH, and PCA but not FEN, shifted the peak of the inter-response time (IRT) distribution toward shorter intervals, MDMA decreased peak location only at the highest dose. All five drugs caused a dose-dependent decrease in peak area, indicating a loss of schedule control on the DRL 36-s schedule. Consistent with in vitro and in vivo release studies, the differential results of these five drugs on DRL 36-s schedule performance suggest a predominant dopamine role for AMPH and METH, a predominant serotonin role for FEN, and different degrees of combined dopaminergic and serotonergic roles for MDMA and PCA in the mediation of the task.
