Short-term retention of habituation in the rat: A developmental study from infancy to old age.

Abstract
Allowed 168 infant, weanling, adult, and elderly Blue Spruce hooded and albino rats to habituate to a simple exploratory situation and then tested them for retention after 1 min, 1 hr, or 24 hrs. Infants habituated more slowly than older Ss as indicated by time to habituate and response frequency measures. No age differences were found after a 1-min retention interval, which suggests that the final levels of original habituation did not differ. However, after longer intervals (1 hr and 24 hrs), infants showed poorer retention of habituation than the older Ss. (17 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
