Figure 4

Behavioral response to light (conditioned response). Conditioned response is presented in terms of the proportion of distance moved at high velocity on Day 4 relative to that on Day 1. A proportion of 1.0 represents no change in response to the conditioned stimuli (CS) across days of training. All three groups exhibited a similarly small reduction in activity during the intertrial intervals (ITI) across days. Group no shock control (NOS) showed a similar pattern of response to the CS, with relatively little change across days. Both groups unpaired (UNP) and NOS suppressed activity during the CS somewhat on Day 4 relative to Day 1, with the most suppression of activity by group experimental (EXP). Error bars represent standard error, and * represents significance at p ≤ 0.05 (n = 8–10 in each group).
