The law enforcement community has had a longstanding interest in the development of techniques to increase accuracy and detail of reports by eyewitnesses and victims (Whitehouse et al. 2005). There are a number of advocates for the technique of hypnosis. However, it is difficult to prove the claims of success given that the criteria for determining how helpful hypnosis was is subjectively determined and vary from case to case. Hypnosis is associated with increased overall production (that may be inaccurate) rather than a selective enhancement of correct recall (Whitehouse et al. 2005). Many controlled studies found hypnosis to have no unique properties and often yields less accurate information (Whitehouse et al. 2005).

2011). Hypnotic interviewing has been replaced by an alternative investigative interviewing called the cognitive interview. When used appropriately, the cognitive interview does not excessively influence incorrect responses and susceptibility to leading questions (Wagstaff et al. 2011). Applying hypnotic methods may help create relaxed and passive mode, which may help facilitate memory for certain kinds of material. Creating this atmosphere may help the client remember a face (Wagstaff et al. 2011). Components of hypnosis, such as eye closure, may help to reduce the distractions and aid with the production of visual and auditory imagery. According to Wagstaff et al. (2011), very brief focused meditation technique combined with eye closure may significantly enhance memory for both auditory and visual material without increased errors (Wagstaff et al. 2011). This may potentially provide a practical and reliable alternative to the longer and time consuming method of the cognitive interview. Although it may be useful to use the hypnotic methods as a brief memory facilitator for police procedures, it is important to note that it is less effective than a full cognitive interview
Psychological research shows that eyewitness testimony is not always accurate, therefore it should not be used in the criminal justice system. Discuss.
recall and the use of too many leading questions during interviews. Method: Participants were tested to see how affected they were by the treatment. hypnosis, those who were found to be medium to highly susceptible. were shown a film of a bank robbery. They were then split into 3 groups - hypnosis group, relaxation group and wake group. Participants were asked to come back a week later and were individually interviewed by being asked to use either the guiding
Many of today’s interrogation models being utilized in police investigations have an impact on false confessions. The model that has been in the public eye recently is the social psychological process model of interrogation known as the “The Reid Technique.” There are two alternatives used by the police today to replace the Reid Technique, one is the PEACE Model and the other is Cognitive Interviewing. These methods are not interrogation techniques like Reid but interview processes.
For this book report, I decided to read Hugo Münsterberg's On the Witness Stand. This book contains essays on psychology and crime and eyewitness testimony. Today this book is used as a reference for many issues in forensic psychology. For this report, I focused on two chapters of the book: Illusions and the Memory of the Witness. I am going to first summarize the two chapters I read then talk about what was going on at the time this book was written. I will then report some of the research in the book, and finish with my opinion on how this book has contributed to the literature and how it relates to the current knowledge of forensic psychology.
In Laurence Armand French Ph.D. and Thomas J. Young Ph.D.’s article The False Memory Syndrome: Clinical/Legal Issues for the Prosecution talks about memory recall being an unreliable form of evidence in the Criminal Justice System. French and Young state that hypnosis and lie detector tests are a misconception because “the cognitive interpretations of the emotional/autonomic aspects of the central nervous (CNS) and peripheral nervous systems are not true indicators of reality,” (p. 38).
Elizabeth Loftus, is a psychologist, mainly concerned with how subsequent information can affect an eyewitness’s testimony. Loftus has focused on misleading information in both the difference in wording of questions and how these questions can influence eyewitness testimony. This research is important because frequently, eyewitness testimony is a crucial element in criminal proceedings. Throughout Loftus’s career she has found a witness’s memory is highly flexible and subject to being influenced. The classic study by Loftus and Palmer (1974), illustrates that eyewitness testimony can be influenced by leading questions and ultimately proved unreliable.

In the court of law, eyewitnesses are expected to present evidence based upon information they acquired visually. However, due to memory processing, presenting this information accurately is not always possible. This paper will discuss the reliability of eyewitness testimony, its use in a relevant court case, and how the reasonable person standard relates to eyewitness testimony.
Hypnosis and Weight Loss Hypnosis has many practical uses, and these days it is becoming increasingly popular as a method of behavior modification. The Internet contains many advertisements for self-help programs that use hypnosis to reduce stress, quit smoking, or lose weight. In the area of hypnosis and weight loss, there are many web sites for both products and services for sale that promise to help anyone lose weight. Hypnosis uses suggestions to change a person's behavior and eating habits in order to facilitate weight loss. What are the expected outcomes?
Although testimony by witnesses is an invaluable tool in assisting judges and juries’ efforts to convict violent criminals, however, there are major issues with witness memory and recall of events. For this reason, officers of the court use the professional psychological research to deal with the likelihood of significant errors in eyewitness testimony. The fact is, human memory begins to fade within the first hour. In addition, memory continues to decrease for the next nine hours and beyond. Furthermore, recall of a crime can be affected by other factors. As a consequence of major mistakes in observer evidence many innocent victims spend years in prison before they are vindicated and
To our knowledge, eyewitness memory could be simply defined as a person’s episodic memory that he or she has been a witness of a certain criminal event. However, psychologists have discovered that the confidence of memory recall of eyewitness, would increase significantly by asking them the simple question, (e.g., Do you see the perpetrator below the following pictures?), even though the feedback
Contemporary societies in the United States are comprised of multicultural groups. Each person in these groups possesses different cognitive abilities that are possibly accompanied with distinct mental barriers that inhibit regions of the brain. The difficulties of remembering specific and accurate details of events transpired is a pervasive occurrence for those that have been present while a crime is committed. This is problematic as a person’s memory of a crime committed is crucial to law enforcement officers’ ability to apprehend the correct person responsible for having committed a crime. Law officials frequently request dependable eyewitness memory from bystanders present, as their ability to accurately identify the offender
Loftus’s work and the studies that followed have demonstrated that an individual’s memory of an event can easily be distorted by post-event information, which is provided through questions that the researcher or police officer in case of a real life crime might ask the witness. But not only researchers’ questions have been found to distort memory. Several studies have indicated that when witnesses discuss an event together they can mistakenly incorporate elements of each other’s memories into their own memories (e.g., Gabbert, Memon, & Allan, 2003; Paterson & Kemp, 2006). ...
Learn any slang or definitions when needed (for example, prisoners use different words when talking about other inmates). Don’t assume they refer to themselves using the same terms that you would use
Loftus has focused the bulk of her career on both the psychological and legal aspects of distorted or false memories, and her work demonstrates the facility with which memories and beliefs can be molded. Her findings regarding the strength of eyewitness testimony and repressed traumatic memories have helped change the notion that such testimony is absolutely reliable (Zagorski, N., 2005).”
