The Effect of Varying Reward Treatments on Performance and Learning Acquisition in Mice

Abstract

An animal’s ability to learn and perform perceptual tasks is highly variable, depending on factors such as reward type. Using a more favorable reward is expected to positively influence motivation and performance. The present study examined the effects of using a highly palatable caloric reward in lieu of standard water reward. It was hypothesized that a high caloric reward solution would facilitate a faster learning rate on an auditory discrimination task. By examining the effects of alternative reward treatments on performance in an auditory discrimination task, we can determine optimal treatment conditions in which mice learn most efficiently. These results could further elucidate the relationship between caloric intake, nutrition, and arousal.
