Abstract
The relationship between the resistance to extinction of a running response and the number of acquisition trials (Ng) was investigated. Six groups of rats received either 10, 20, 40, 60, 80, or 100 rewarded trials followed by 80 nonrewarded extinction trials at five trials per day with an intertrial interval of 18 min. The mean numbers of trials to extinction criteria of 40 and 120 sec. were negatively related to Ng, and running speed in early extinction was nonmonotonically related to Ng. These data were contrasted with those previously obtained in the Skinner box. In addition, the mean number of trials on which avoidance responses occurred in extinction was positively related to Ng and the mean number of trials to the first avoidance response was negatively related to Ng. These latter relationships are consistent with interference theories of extinction which stress the acquisition of competing avoidance responses.This publication has 5 references indexed in Scilit:
