**Study 4 Description** The previous studies have examined the extent to which people update their beliefs about their abilities after completing a difficult task. Belief updating has been measured by taking the difference between pre-task assessments and post-task assessments. An assumption of this measure, though, is that people remember their initial assessments and are knowingly lowering their rating post-task. Another possible explanation could be that people are misremembering or unknowingly shifting their memory of their initial ratings downward and believe that they are giving equivalent pre- and post-ratings. Study 4 examines this possibility. All participants complete a procedure similar to Studies 1 and 2, in which they are randomly assigned to report their prediction of their performance on the anagram task either before (Preregistration condition) or after (Hindsight condition) completing it. In addition, one third of participants will be assigned to provide one pre-task rating of their verbal ability and one post-task rating (as was done in the previous studies, Control condition). A second group will be asked, at the end of the study after providing their post-task rating, to try and remember their initial verbal ability rating (Remember condition). Finally, a third group will not provide a pre-task rating and will be asked, after providing their post-task rating, to report what they think *would* have been their pre-task rating (Would condition). These additional conditions will help us to understand whether individuals are aware of their belief updating.
