The construction of an activity wheel to exercise subhuman primates is described and a sample cumulative record of steady-state responding is presented. The wheel consists of a Lucite and aluminum bar circular cage which rotates freely on four roller bearings inside two stationaly Lucite walls. The aluminum bars act as a circular treadmill and as a shock grid for conditioning the animals. A free-operant avoidance paradigm utilizing visual and auditory control stimuli can be used to condition and maintain stable rates of responding. Pressplates and one-plane readouts are also installed on one stationary wall to permit the training of animals to additional discriminated avoidance tasks.
