Comparison of two techniques for the development and maintenance of tracking behavior in monkeys

The present study compared two methods by which animal subjects can be taught to perform a pursuit tracking task. Rhesus monkeys were trained to track in order to avoid shock (Method No. 1) or to obtain food (Method No. 2). One animal received training under both procedures. Both techniques were effective; however, the method utilizing shock produced faster learning and more efficient performance. The possible reasons for these differences are discussed along with generality of the results. These methods should have implications for tracking research in which animal models are required.
