Abstract
Rats were conditioned to depress a bar to receive food. Four equivalent groups were trained with 1, 12, 24 and 48 hrs. of food deprivation preceding the exptl. period. After conditioning had taken place all animals were given food for 24 hrs. After this there was a 24 hr. deprivation period followed by 2 exptl. extinction tests 30 mins. apart. The number of extinction responses and the total time of extinction indicated that between 1 and 24 hrs. of privation resulted in faster learning. Rate of the conditioned response was not a reliable measure.This publication has 3 references indexed in Scilit:
