A forensic psychologist conducted a study to examine whether being hypnotized during recall affects how well a witness can remember facts about an event. Eight participants watched a short film of a mock robbery, after which each participant was questioned about what they had seen. The four participants in the experimental group were questioned while they were hypnotized and the researcher recorded their accurate responses. The four participants in the control group (not hypnotized) were questioned and the researcher recorded theiraccurate responses. Here are the results:
