Implicit Detection Of Change: Can We Do Without Awareness?
People generally assume that in order to perceive change, a person must consciously attend to the object that undergoes some kind of displacement or alteration. For example, one day the family car appears intact, but then at some point I notice that the left-front fender has been bent. Psychological theory, too, has highlighted the central role of attention and awareness in change perception (Rensink, 2002; Rensink et al., 1997; Werner and Thies, 2000). D. J. Simons and R. A. Rensink (2005) are very explicit on this point: "Attention is needed to see change".
