It has been suggested that hypnosis techniques may have the potential
to enhance eyewitness memory in forensic investigations. However, labo
ratory research shows that increases in recall with hypnosis technique
s are often associated with decreases in accuracy, false confidence in
incorrect information, and increased suggestibility to leading questi
ons and misleading post-event information. These problems limit the us
efulness of hypnosis as an interviewing procedure. However, in practic
al investigations, many factors associated with hypnosis, apart from t
he hypnotic induction itself, might lead to memory enhancement compare
d with standard police interviews. For example, hypnotic interviewers,
because of their psychological, clinical, and interpersonal skills, m
ay be better interviewers than police officers. They may use effective
interviewing strategies such as those associated with the ''cognitive
interview''; a procedure which has the potential to enhance recall by
approximately 35% without the problems of memory distortion associate
d with hypnosis. It is concluded, therefore, that a cognitive intervie
w procedure should be used in preference to hypnosis. (C) 1998 John Wi
