Abstract

Rats were trained to escape shock by running from the white to the black half of a 2 compartment box. The white compartment was divided by a screen, to form an enclosure for a stimulus animal. 50% of the Ss ran the acquisition trials with another animal present (Aw), while the others ran alone (Aa). These groups were further subdivided into extinction-with-animal (Ew) and extinction-alone groups (Ea). The Aw-Ea group appeared to show more rapid extinction than the other groups. Relevance of these data to concepts of counter-conditioning and novelty is discussed. From Psyc Abstracts 36:02:2EK58K. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
