【 摘 要 】

Research on recognition memory has a long tradition in ERPs (see Yonelinas, 2002; Vilberg and Rugg, 2008 for reviews). One assumption is that recognition memory involves two distinct processes: familiarity and recollection. Familiarity refers to the feeling that a presented stimulus has been studied before, while recollection involves somewhat conscious retrieval of information associated with the respective study episode. Recently, Kafkas and Montaldi (2011, 2012) suggested that familiarity and recollection could also be distinguished in the size of the pupil. The claim is that the pupil dilates more for recollected than familiar stimuli. The distinction between familiarity and recollection in pupil size, however, is entirely based on remember/know paradigms. In Kafkas and Montaldi (2012), participants judged whether a presented stimulus was “old” or “new” and, in case of an “old” response, whether they can retrieve specific information of the study episode (“recall” response) or not (“familiar” response), and, in case of a “familiar” response, they then estimated the degree of familiarity (“weak” or “moderate” or “strong”).
