K. Roberts et Gf. Wagstaff, THE EFFECTS OF BELIEFS AND INFORMATION ABOUT HYPNOSIS ON THE LEGAL DEFENSE OF AUTOMATISM THROUGH HYPNOSIS, Psychology, crime & law, 2(4), 1996, pp. 259-268
The aims of this study were to assess the impact of public conceptions
about the nature and coercive powers of hypnosis, and information reg
arding different approaches to hypnosis, on the plea of automatism thr
ough hypnosis in a criminal trial. Subjects were assigned to three gro
ups. Two were presented with criminal cases in which automatism throug
h hypnosis was implicated, as well as duress; one of these groups rece
ived information about different approaches to hypnosis. The third rec
eived the same cases, but with duress alone. Results showed that, when
automatism through hypnosis was implicated as well as duress, the def
endant offering the plea was judged less responsible, however, he was
not judged less guilty than when duress alone was the defence. Also, s
ubjects presented with the plea of automatism tended to be more scepti
cal about the idea than those not presented with this plea. The provis
ion of information on different approaches to hypnosis was largely ine
ffective in altering beliefs and judgments. Judgments of guilt and res
ponsibility were, however, strongly influenced by beliefs about automa
tism through hypnosis.
