Effects of Food Deprivation on the Performance of a Two-Turn Task in a Temporal Circular Maze

Abstract

Ten hooded rats were trained to perform a two-turn task in a temporal circular maze. The effects of levels of food deprivation (2, 26, 50, 74, 98, 122 hr.) on performance were evaluated. It was found that the correct responses were not affected, but both running time and competing behaviour decreased significantly with increase in hours of food deprivation. In a second experiment 8 rats were trained in a similar way and after attaining a stable performance, were run for a further 4 sessions at 24 hr. deprivation, and then at 72 hr. deprivation. The results precluded the possibility that the results obtained in Experiment I were due to practice effects, and support the findings on the effects of deprivation.
