This study examines hindsight bias in relation to performance in the change detection (i.e., 'flicker') paradigm. In order to determine confidence ratings and predictions about performance,participants provided ratings at three time points. Following a verbal description of the flicker paradigm, the pre-test was administered. Next, three flicker trials were administered, followed by the mid-session test, three more flicker trials, and finally the post-test. Critically, the post-test asked participants to remember and report their initial confidence ratings and predictions about their performance. The hypotheses were that the participants would have an initial overestimateof ability to detect change that would decrease after participation in the change detection paradigm, and that post-test responses would be significantly different than the initial ratings, showing hindsight bias. Results showed that there was an initial overestimate of confidence in change detection ability, and that hindsight bias was evident in the measure of predicted performance level, but not in confidence ratings. These findings are important in many aspects of life that require us to understand the role of hindsight bias in recalling past events, such as in legal settings involving remembered reports of witnessing a crime.
