“…It is possible that this reflects an interruption of operant responding by postprandial activities, such as licking in the vicinity of the dipper aperture (cf. Iversen, 1978;Staddon, 1977), which may be more prevalent following the consumption of the larger volume of the sucrose solution. Such an effect would have a more marked effect on response rate under high reinforcement frequencies, and might therefore result in a reduction in the value of Rmax.…”

Three rats were exposed to variable-interval schedules specifying a range of different reinforcement frequencies, using three different volumes of .32 molar sucrose (.10, .05, and .02 milliliters) as the reinforcer. With each of the three volumes, the rates of responding of all three rats were increasing, negatively accelerated functions of reinforcement frequency, the data conforming closely to Herrnstein's equation. In each rat the value of the constant K(H), which expresses the reinforcement frequency needed to obtain the half-maximal response rate, increased with decreasing reinforcer volume, the values obtained with .02 milliliters being significantly greater than the values obtained with .10 milliliters. The values of the constant R(max), which expresses the theoretical maximum response rate, were not systematically related to reinforcer volume. The effect of reinforcer volume upon the relationship between response rate and reinforcement frequency is thus different from the effect of the concentration of sucrose reinforcement: In a previous experiment (Bradshaw, Szabadi, & Bevan, 1978) it was found that sucrose concentration influenced the values of both constants, R(max) increasing and K(H) decreasing with increasing sucrose concentration.

Four rats were exponsed to variable-interval schedules specifying a range of different reinforcement frequencies. The effects of two doses of d-amphetamine (1.6 and 3.2 Zmol/kg) upon performance maintained under each schedule were examined. In the case of each rat, the response rates observed under control conditions (no injection or injection of the vehicle alone) were increasing, negatively accelerated functions of reinforcement frequency, the data conforming closely to Herrnstein's (1970) equation. In each rat, d-amphetamine (3.2 ,umol/kg) significantly reduced the value of the constant Rm,Z, which expresses the theoretical maximum response rate. In each rat, the value of KH, which expresses the reinforcement frequency needed to obtain the half-maximal response rate, was also reduced, although this only achieved statistical significance in the case of one rat. When the proportional change in response rate in the presence of the drug was plotted against the response rate under control conditions on double logarithmic co-ordinates, linear functions of negative slope were obtained; in each rat the slope was steeper and the value of the control response rate at which d-amphetamine exerted no effect was lower in the case of the higher dose (3.2 jumol/kg) than in the case of the lower dose (1.6 Smol/kg).Key words: Herrnstein's equation, response rate, reinforcement frequency, d-amphetamine, rate dependency, variable interval, lever press, rats Herrnstein (1970) proposed an equation of the following form to describe the relationship between response rate (R) and reinforcement frequency (r) in variable-interval schedules of reinforcement: R = Rmnax * rI(KH+ r) (1) where Rmax and KH are constants expressing the theoretical maximum response rate that can be generated in a variable-interval schedule, and the reinforcement frequency needed to obtain the half-maximal response rate respectively (Herrnstein, 1970,
