Bp. Allen et Ds. Lindsay, AMALGAMATIONS OF MEMORIES - INTRUSION OF INFORMATION FROM ONE EVENT INTO REPORTS OF ANOTHER, Applied cognitive psychology, 12(3), 1998, pp. 277-285
Numerous researchers have reported that exposure to misleading posteve
nt information (MPI) regarding details in a witnessed event can lead p
eople to report false details from the MPI when asked to report the wi
tnessed event. In such studies, the MPI is presented to participants i
n the context of information about the witnessed event. This experimen
t tests the hypothesis that postevent exposure to information that par
ticipants know is not about the witnessed event can, nonetheless, affe
ct performance on tests of memory for that event. As predicted, when a
sked to report details of an event depicted in a slide show, participa
nts tended to intrude details mentioned in a recent postevent narrativ
e that described a different event. (C) 1998 John Wiley & Sons, Ltd.
