Two groups of albino rats were run in a shock avoidance-wheel turning situation in a comparison of two methods of producing experimental extinction. The Guthrie "toleration" method and the more conventional "response-no reinforcement" method were employed. Results of the extinction series show 6.5 mean number of responses for the toleration group to 14.4 for the conventional extinction group. Conclusions are that this confirms one of Guthrie's theoretical ideas and calls for a reformulation of Hull's theory of extinction. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
