Random bred male animals (N = 48 rats) underwent classical fear conditioning, an extinction trial, and a subsequent fear retention test either in the morning or in the afternoon. Half of the animals in both groups had been deprived of food for 18 hours prior to testing and were offered some food in the final fear retention test, whereas the others carried on feeding ad lib. The four groups were further split up into groups of three animals with a duration of the extinction trial of either 0, 15, 30, or 60 sec. Food deprivation had no significant effect on the fear retention data. But animals which had been tested in the afternoon showed greater fear reduction following a short duration of extinction than after a long duration. Animals tested in the morning, on the other hand, profited more from longer duration of extinction
