Delay Of Reward

Ss receiving partial delay of reward showed better differential learning with a brightness cue given on the delay trials than did Ss receiving partial reinforcement for which the cue was given on nonreward trials. Partial delay of reinforcement resulted in faster start latencies on the trials in which reinforcement was immediate than occurred for continuous immediate reinforcement. The decremental effects of constant delay of reinforcement on performance were eliminated when a sufficient number of trials were given.

Operant Procedure

Three different volumes (.01, .4 and .7 ml.) of a 32% sucrose concentration were employed in a free-operant bar-press study. In acquisition performance was a decreasing function of volume while in extinction greater persistence of performance was obtained for the .4 and .7 groups than for the .01 group. The extinction results were contrasted with those obtained in discrete-trial experiments which had employed a comparable range of volumes and number of reinforcements but which reported that large volumes tended to decrease rather than increase resistance to extinction.

Delay Of Reward

3 groups of 4 rats completed run-to-lick contingencies with delay of reward intervals of 0, 3, and 10 sec. imposed between the FR 10 running requirement and delivery of a 4% sucrose solution. Following acquisition sessions, Ss received extinction sessions which continued until instrumental responding stabilized. The experimental design continued over 4 replications. There were no differential effects of delay of reward conditions on either total acquisition or extinction responding.
