Monitoring Conscious Recollection via the Electrical Activity of the Brain

Abstract

Although another person's experience of recollection cannot be observed directly, we have found that the underlying operations can be monitored using noninvasive electrophysiological techniques Results from two experiments showed that brain potentials elicited 500 to 900 ms after the onset of visually presented words vary systematically in amplitude with manipulations that influence the extent to which subjects engage in recollective processing These brain potentials can thus be construed as correlates of the subjective experience of recollection
