title: Exploring the informational sources of metaperception: the case of Change Blindness Blindness.
abstract: Perceivers generally show a poor ability to detect changes, a condition referred to as "Change Blindness" (CB). They are, in addition, "blind to their own blindness". A common explanation of this "Change Blindness Blindness" (CBB) is that it derives from an inadequate, "photographical" folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time and perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration.
