Nm. Steblay et Rk. Bothwell, EVIDENCE FOR HYPNOTICALLY REFRESHED TESTIMONY - THE VIEW FROM THE LABORATORY, Law and human behavior, 18(6), 1994, pp. 635-651
The evidence for differences in recall accuracy for hynotized vs. nonh
ypnotized eyewitnesses in forensically relevant settings was examined
through a meta-analytic review of 24 research studies. Recall accuracy
for nonleading questions after a 1- to 2-day delay favored the hypnot
ized subjects (d = .46); however, less accurate recall was evidenced f
or hypnotized subjects following a delay of less than 24 hours (d = -.
29) or a one-week delay (d = -.24). The recall of hypnotized subjects
also displayed more intrusion of uncued errors and higher levels of ps
eudomemory. Hypnotized subjects also expressed higher levels of confid
ence in recall accuracy compared to nonhypnotized subjects. Caution is
urged regarding use of hypnotically refreshed memory.
