Interaction effect between the reinforcement frequency (left: high, right: low), the reward magnitude (blue: small, red: large), and the experimental day on a pass rate, b approach index, c latency to pass the correct door, and d success rate with 95% confidence bands. Reinforcement frequency and reward magnitude had a significant interaction effect on the latency to pass with large-reward sharks learning significantly faster when subjected to a low reinforcement frequency (color figure online)
