The precise mechanism underlying RB has been extensively debated.
Nancy Kanwisher has argued that it involves failure to
tokenize the second appearance of a repeated stimulus and create a separate mental record for the second instance. Tokenization, here, means the ability to identify the second stimulus as a second individual, or token. Lack of tokenization means that the second appearance of the stimulus is being dropped from short term memory before it can be identified, and hence, remains unreportable. However, Whittlesea and colleagues have argued that repetition blindness arises from a failure to properly reconstruct the list, both online and post list. This failure to properly reconstruct the list arises from the poor encoding cues that are the result of the RSVP task. == See also ==
