Partial Reinforcement Training

3 groups of albino rats were given 96 acquisition trials in a runway. One group (C) was given consistent reinforcement, while the other 2 groups (PN, PR) received the same partial reinforcement pattern, RRNNRRNN, on each day. Following Trial 4 for Group PN and Trial 5 for Groups PR and C., Ss were given intertrial reinforcement. In extinction the groups were ordered PR, PN, C, with Group PR being most resistant to extinction. Taken in conjunction with the results of studies involving abbreviated training, the findings were interpreted as supporting the view that the same variables or processes influence extinction performance following both abbreviated and extended training. The results were further interpreted as supporting the modified aftereffects hypothesis.

Observing Responses

College students made observing responses in a discrete-trial instrumental-conditioning situation. Intertrial intervals from 1 to 10 sec. were factorially combined with patterns of reinforcement involving different total numbers of non-reinforcements, numbers of successively occurring non-reinforcements, and numbers of non-reinforced—reinforced trial transitions. In agreement with previous studies with rats, Exp. 1 indicated that intertrial interval interacts with pattern of reinforcement and accounts for a large percentage of the total variance. Contrary to previous studies with rats, Exp. 2 indicated that the effects of intertrial interval with humans are due to more than just those intertrial intervals near a non-reinforced—reinforced trial transition. Though much of the basic human and animal partial-reinforcement data are similar, the theoretical accounts apparently should differ.

Reinforcement Procedure

2 varied magnitude of reward instrumental runway studies with rats were conducted to ascertain whether the sequential variables, intertrial reinforcements and number of successive small magnitude of reward trials (S-length) would influence resistance to extinction (Rn) in a manner similar to that of comparable variables in the partial reinforcement (PR) situation. Exp. I indicated that S-length affects Rn in the same manner as the number of consecutive nonreinforced trials in the PR experiment. Contrary to the results of PR experiments, in Exps. I and II, the intertrial reinforcement procedure did not reduce Rn. The results of the two experiments indicate, however, that animals receiving identical goal events but differing in the sequence of such events exhibit differential Rn.
