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.

Group A

Three groups of rats ran 108 trials in a straight runway, one trial every 3 days. On the first 44 trials, one group received continuous (and immediate) reinforcement (CRF), a second group 50 per cent partial reinforcement (PRF), and the third group a 50 per cent schedule of partial delay of reinforcement (PDR). All groups received CRF on the next 20 trials, and extinction on the last 44 trials. The PRF and PDR groups extinguished at approximately the same rate, and significantly more slowly than the CRF group.

Partial Reinforcement Training

Rats were trained in a straight-alley runway in two replications of 24 rats each. Two groups received partial reinforcement training with one or three successive nonreward trials (N-length), two groups received partial delay training with one and three successive delayed trials (D-length), and two additional groups received immediate continuous reinforcement. Following training all groups were shifted to continuous delay. The results indicated that D-length increased resistance to continuous delay, however, N-length did not have the corresponding effect. The performance of both N-length groups equalled that of the D-length 3 group, but the D-length 1 group was inferior and not different from the continuously reinforced control groups. These results were discussed in terms of Capaldi's (1967) sequential theory of instrumental learning.
