On the search for the neurophysiological manifestation of recollective experience . M.E . Smith ( 1993 ) obtained event-related brain potentials ( ERPs ) from subjects performing a recognition memory task using " remember " ( R ) and " know " ( K ) judgments , and reported observing in the ERP a " neurophysiological manifestation of recollective experience " as a difference between the positive waveforms elicited by stimuli that yielded R and K judgments . We replicated his experiment and examined the componential structure of the R > K effect in two ways . First , we found that correction for P300 latency jitter eliminated the effect reported by Smith . Second , the application of principal component analysis indicated that the positive waveform elicited by the words in the test list was a P300 . These analyses do not support the hypothesis that there is a new component ( the " memory-evoked shift " ) that is a specific manifestation of recollection .
