Under widely distributed practice in a straight alley, partially reinforced goldfish did not exhibit greater resistance to extinction than consistently reinforced animals. The relative influence of equating trials or reinforcements in generating the partial reinforcement effect could not be evaluated since the partially reinforced Ss were significantly less resistant than either the equated-reinforcement Ss or the equated-trials Ss.

To test the discrimination hypothesis of the partial reinforcement effect in extinction, partial or continuous reinforcement trials were interpolated between the initial training trials of partial or continuous reinforcement and the extinction period. 112 children from Grades 2 and 3 participated in one of four conditions. Children receiving two consecutive blocks of partial reinforcement showed the greatest resistance to extinction, children receiving two consecutive blocks of continuous reinforcement showed the weakest resistance, and those receiving partial reinforcement followed by continuous reinforcement or vice versa showed intermediate levels of resistance. Discrimination between training and extinction does not seem to be the critical factor involved in the partial reinforcement effect. The results were discussed in terms of a stimulus analyzer or a sequential analysis model.

2 experiments investigating the effects of intertrial reward on resistance to extinction following partial reward schedules containing N-lengths (number of consecutive nonrewards preceding a rewarded trial) of 1, 2, or 3. It was found that intertrial rewards completely eliminated the partial reinforcement effect for all N-lengths when run times were considered but had no effect on goal times. These data were discussed in terms of their relevance to the modified aftereffects hypothesis and previous investigations of intertrial reward.

40 albino rats were assigned randomly to the cells of a 2 × 2 factorial design consisting of per cent reinforcement (50% and 100%) by deprivation (high and low). Speed measures were obtained from two segments of a straight-alley runway for 80 acquisition and 56 extinction trials with 4 trials given per day. Deprivation effects were found over the closely spaced trials within daily sessions for both acquisition and extinction. In extinction the interaction of drive and per cent reinforcement within daily sessions lends support to a frustration-theory explanation of extinction behavior. The lack of deprivation-produced differences in the size of the partial reinforcement effect over days is also consistent with this explanation.

One group of 10 male albino rats was given partial reinforcement while the other 10 rats received continuous reinforcement in a straight alley. Subjects then experienced five consecutive stages of Extinction 1, Continuous Reinforcement 1, Extinction 2, Continuous Reinforcement 2, and finally, Extinction 3. Analysis showed the partial reinforcement effect in extinction was sustained over two stages of extinction and two stages of continuous reinforcement, since subjects receiving partial reinforcement ran faster than rats given continuous reinforcement throughout all three of the extinction periods. The results seem to support those of Amsel's (1967) and Capaldi's (1967) theoretical formulations of the partial reinforcement effect in extinction.

4 groups ( ns = 10) of albino rats were given 40 acquisition and 25 extinction trials in a straight runway under one of the following conditions: (1) continuous reinforcement with an exhaust fan operative; (2) continuous reinforcement with exhaust fan operating but blocked from exhausting; (3) partial reinforcement with exhaust fan operating but blocked, and (4) partial reinforcement with exhaust fan operative. The results imply that exhausting odor(s) under a partial schedule increases running speeds during acquisition and resistance to extinction. The study points to important methodological implications for partial reinforcement research.

Frustration theory (Amsel, 1958) is unable to explain partial reinforcement effects following limited acquisition training. It is suggested that attempts to explain these findings may have implications for conditioning theories in general, and that more attention should be given to the early acquisition process.
