Retention of Avoidance: Time since Original Training or Time since Shock

Abstract

4 groups of 9 Holtzman rats were run on a brightness discrimination task in a T-maze under the conditions of shock-train-shock-retest or transfer. Under like manipulation intervals of 1 hr. or 24 hr. between shock-train and shock-retest or transfer and with constant 24-hr. intervals between train-shock, there was no decrement in avoidance for the 1-hr. retest group nor an increment for the 24-hr. transfer group. This supports memory retrieval rather than behavioral inhibition.
