The effect of feedback on perceptual learning and confidence

Feedback is frequently used as a tool to improve performance in many tasks. However, the mechanisms by which feedback improves performance remain unclear. Using a motion direction discrimination paradigm, the present study aims to investigate the effects of True, Fake-positive and Fake-negative feed...

However, the mechanisms by which feedback improves performance remain unclear. Using a motion direction discrimination paradigm, the present study aims to investigate the effects of True, Fake-positive and Fake-negative feedback on performance and confidence, and whether their changes would transfer to an untrained stimulus. True feedback was generated based on participants’ actual response accuracy. Fake-positive feedback was generated based on a predetermined “correct” probability that was higher than the actual proportion of correct responses, and fake-negative feedback messages were generated based on a predetermined “correct” probability that was lower than the actual proportion of correct responses. In other words, True feedback reflected participant’s actual performance while fake feedback was independent of their actual response accuracy. Results showed that the effects of True and fake feedback were comparable and did not significantly improve accuracy or increase confidence. Learning was found to transfer to an untrained stimulus under the fake-negative feedback condition. This finding suggests a potential role for fake-negative feedback in facilitating generalization of learning.
