Across many topics, eyewitness testimony remains a vivacious research area. The American Psychology-Law Society lists more than 1,400 references on the topic from 1883 and 2006. Eyewitness testimony research established roots as a research area in psychology over 100 years ago in Germany. There existed a strong German interest in eyewitness testimony (Sporer, 2006), and
Every year in North America at least 75,000 people are identified from police lineups and subsequently prosecuted. There are hundreds of documented cases in which mistaken eyewitness identification has led to false imprisonment. Although it is impossible to know how often eyewitnesses make mistakes, it is known that mistakes are made. For example, of approximately
Eyewitness memory plays a pivotal role in many criminal trials. A substantial body of psychological research on eyewitness memory has developed over the years. This research paper examines various types of eyewitness memory, factors that influence eyewitness memory, methods of improving eyewitness memory, and how eyewitness memory is evaluated in the course of investigations and
Eyewitness research has repeatedly shown that exposure to postevent information can affect a witness’s ability to accurately report details of an originally encoded event.

Even when each person has witnessed the same event, their
Police investigators will frequently request that witnesses to a crime provide verbal descriptions of the alleged perpetrator.

People who wear a disguise are attempting to conceal their appearance or change how they look. Culprits may wear any of a number of possible disguises for the commission of a crime. For example, a bank robber may wear a ski mask, or dark sunglasses and a knit cap. Changes in facial characteristics may result
A substantial base of laboratory research is now available to aid our understanding of eyewitness identification processes and to support recommendations for lineup reform. However, there are also a limited number of peer-reviewed, published studies that measure eyewitness responses in real police cases. Although few, the studies include large-scale investigations involving a sizable combined sample
This research paper focuses on the degree to which experts and others are persuaded that each of a number of factors influences the accuracy of eyewitness identifications. Supreme Court cases, among them United States v. Amaral (1973) and Daubert v. Merrell Dow Pharmaceuticals (1993), have opened avenues of research addressing how the influence of various
Lay beliefs about factors that influence the reliability of eyewitness testimony have been assessed with a variety of survey and experimental methods. When compared with expert opinion about the effects of these factors, the lay public frequently holds beliefs that would be considered incorrect in the light of psychological research on eyewitness memory. A brief
The use of hypnosis to enhance the memory of a witness to a crime often results not only in some additional accurate recall of information about the event but also in the incorporation of additional misinformation into the witness’s memory of the event and a general increase in his or her confidence in the veracity
