Identifying the Culprit: Assessing Eyewitness Identification makes the case that better data collection and research on eyewitness identification, new law enforcement training protocols, standardized procedures for administering line-ups, and improvements in the handling of eyewitness identification in court can increase the chances that accurate identifications are made. This report explains the science that has emerged during the past 30 years on eyewitness identifications and identifies best practices in eyewitness procedures for the law enforcement community and in the presentation of eyewitness evidence in the courtroom. In order to continue the advancement of eyewitness identification research, the report recommends a focused research agenda.

This volume provides a tutorial review and evaluation of scientific research on the accuracy and reliability of eyewitness identification. The book starts with the perspective that there are a variety of conceptual and empirical problems with eyewitness identification as a form of forensic evidence, just as there are a variety of problems with other forms of forensic evidence. There is then an examination of the important results in the study of eyewitness memory and the implications of this research for psychological theory and for social and legal policy. The volume takes the perspective that research on eyewitness identification can be seen as the paradigmatic example of how psychological science can be successfully applied to real-world problems.

Examines traditional safeguards against mistaken eyewitness identification.

Why do police officers, investigators, prosecutors, judges, and others with an interest in eliciting accurate memory-based testimony need to inform themselves of the research literature in experimental psychology that addresses the question of witness memory? The answer is straightforward, from the perspective of a simple cost/benefit analysis. As with so many matters in the administration of public funds, effectiveness holds important rewards. Those who investigate crimes and decide which line of investigation to pursue and which line to postpone or set aside, necessarily make judgments about the likely guilt of suspects based on the information at hand. If they can make these judgments with a high degree of accuracy, everyone benefits. For many cases eyewitness identification is an important component of evidence, prosecution, and plea negotiation. If witness identification is correctly implemented, investigators and prosecutors can make their judgments effectively, and focus their resources more efficiently. A major component of effectiveness requires avoiding expending scarce resources on erroneous prosecutions. It is in everyone's interest to make the best use of the memory of witnesses: to preserve it without changing it; to render it maximally accessible; to provide an environment in which witnesses feel free to report their recollections; and to accurately assess the probable validity of the witness's report, regardless of the witness's certainty or doubts about its accuracy. This volume gathers evidence from various research domains on eyewitness testimony. Although many of the studies discussed deal with eyewitness identification, it is noteworthy that many of them also touch upon other areas of concern to eyewitness researchers, including chapters on: *voice recognition by humans and computers, with particularly detailed instructions on conducting voice "lineup," *differential aspects of recognition memory in children, *elderly eyewitness' memory, *problems of cross-racial identification, *psychological aspects of facial image reconstruction techniques, *person descriptions, *particular benefits of reinstating context as a means to improve eyewitness memory, *problems associated with various research paradigms in the eyewitness arena, and *recommendations on how to conduct lineups and photospreads and their proper evaluation. Differentiated from other literature on this topic by its non-technical language and accessibility to non-professionals, this volume covers a great deal of ground, raises a host of questions, settles some others, and points the way to more effective use and evaluation of what eyewitnesses have to say.
