Delay Component

Following 30 sessions of training on a 60-sec. random-interval schedule of reinforcement, 2 pigeons were exposed to a multiple schedule containing non-contingent and variable delay components that provided equal frequencies of reinforcement. The introduction of the multiple schedule resulted in decreased response rare in both components, with a higher rate maintained under the variable delay. Post-reinforcement pauses were systematically increased during the non-contingent schedule, but no systematic increases in pause duration were noted for the variable delay component.

Response Facilitation

Gradually increased electric shock was superimposed on responding maintained on a VI 60-sec. schedule of reinforcement. Shock was contingent upon the reinforcement producing response and preceded reinforcement delivery. Following total response suppression, shock was removed and then reintroduced at selected intensities. The previously observed monotonic linear relationship between rate of responding and shock intensity was not recorded. Rather, post-reinforcement response bursts and two distinct patterns of response facilitation emerged.

Delay Of Reinforcement

In a fixed interval schedule of reinforcement the only responses to be reinforced are those made when a certain time interval has elapsed since the previous reinforcement. The behaviour of three rats on such a schedule was compared with their behaviour on a schedule where a response made at any time during the interval was reinforced by setting up a reward which was delivered when the interval had elapsed. Response rates were higher in the ordinary fixed interval schedule than in its modified version, and it is argued that this rules out attempts to explain the maintenance of fixed interval performance by delayed reinforcement. Despite the clear difference in response rates, there was considerable similarity between the post-reinforcement pauses developed in the two schedules, and this suggests that pausing is influenced more by temporal than by response contingencies.
