3 white tats were trained to rotate an activity wheel to avoid signaled shocks. Response latencies varied inversely with intertrial intervals and directly with signal-shock intervals. 2 animals responded early in the signal-shock interval and always avoided nearly all shocks. The third animal typically responded late in the interval and was less successful in avoiding shocks.
