EVIDENCE FOR HYPNOTICALLY REFRESHED TESTIMONY - THE VIEW FROM THE LABORATORY

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.
