Abstract
In avoidance learning 60-day-old female rats were somewhat superior to 225-day-old rats during acquisition, followed by 30-day-old rats. Resistance to extinction was directly related to age, the 30-day-old rats extinguishing most rapidly. From Psyc Abstracts 36:01:1EK88D. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
