Abstract

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.
