Training and testing results for Experiment 2.

(A) Training results. Fish were trained to select CS+ and avoid CS−. Each curve represents the individual results of a specific fish. The dashed line at 75% represents the training criterion performance level. (B) Testing results. Fish were trained to avoid CS− and select 18 possible N+. The mean correct selection frequencies for each testing block were calculated. Bars represent standard deviation. The red line at 50% in both figures represents the expected selection frequency if subjects were choosing at random.
