Discrimination Hypothesis

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.

Free Operant Situation

The effects of five levels of training (210, 490, 1470, 2450, 3430 reinforced responses) on extinction performance were investigated. A free-operant bar-press paradigm was employed. A continuous reinforcement schedule was used with .12 ml. of 64% sucrose. Number of bar-presses and duration of time to reach a 1-min. non-response criterion showed that resistance to extinction was an increasing function of the number of reinforcements during training. However, the amount of time required to reach a 5-min. criterion showed the opposite relationship. It was concluded that different criteria reflected different patterns of extinction behavior and that the overtraining extinction effect (decreased resistance to extinction following extended training) could be demonstrated in a free-operant situation if the appropriate criteria were selected.

Fourth Group

Four groups of 16 students were given 120 acquisition trials and 60 extinction trials in a verbal choice task. One group was given 120 continuously reinforced trials, a second group was given 120 partially reinforced trials, a third group was given 60 partially reinforced trials followed by 60 continuously reinforced trials, and a fourth group was given 60 continuously reinforced trials followed by 60 partially reinforced trials. Subjects given partial reinforcement after continuous reinforcement were as resistant to extinction as subjects given partial reinforcement only, and both groups were more resistant to extinction than subjects given continuous reinforcement only. Subjects trained with the partial-continuous order of reinforcement schedules, however, were no more resistant to extinction than subjects trained with continuous reinforcement only.

Resistance To 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.
