The Psychology Of Eyewitness Identification

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.

Eyewitnesses play an important role in criminal cases when they can identify culprits. Estimates suggest that tens of thousands of eyewitnesses make identifications in criminal investigations each year. Research on factors that affect the accuracy of eyewitness identification procedures has given us an increasingly clear picture of how identifications are made, and more importantly, an improved understanding of the principled limits on vision and memory that can lead to failure of identification. Factors such as viewing conditions, duress, elevated emotions, and biases influence the visual perception experience. Perceptual experiences are stored by a system of memory that is highly malleable and continuously evolving, neither retaining nor divulging content in an informational vacuum. As such, the fidelity of our memories to actual events may be compromised by many factors at all stages of processing, from encoding to storage and retrieval. Unknown to the individual, memories are forgotten, reconstructed, updated, and distorted. Complicating the process further, policies governing law enforcement procedures for conducting and recording identifications are not standard, and policies and practices to address the issue of misidentification vary widely. These limitations can produce mistaken identifications with significant consequences. What can we do to make certain that eyewitness identification convicts the guilty and exonerates the innocent? Identifying the Culprit 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. Identifying the Culprit will be an essential resource to assist the law enforcement and legal communities as they seek to understand the value and the limitations of eyewitness identification and make improvements to procedures.

Eyewitness testimony is highly compelling in a criminal trial, and can have an indelible impact on jurors. However, two decades of research on the subject have shown us that eyewitnesses are sometimes wrong, even when they are highly confident that they are making correct identifications. This book brings together an impressive group of researchers and practicing attorneys to provide current overviews and critiques of key topics in eyewitness testimony.

The Handbook of Eyewitness Psychology presents a survey of research and legal opinions from international experts on the rapidly expanding scientific literature addressing the accuracy and limitations of eyewitnesses as a source of evidence for the courts. For the first time, extensive reviews of factors influencing witnesses of all ages-chil

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.

Methods, Measures, and Theories in Eyewitness Recognition Tasks provides a comprehensive review of the fundamental issues surrounding eyewitness recognition phenomena alongside suggestions for developing a more methodologically rigorous eyewitness science. Over the past 40 years, the field of eyewitness science has seen substantial advancement in eyewitness identification procedures, yet theoretical and methodological developments have fallen behind. Featuring contributions from prominent international scholars, this book examines methodological and theoretical limitations and explores important topics, including how to increase the accuracy of identifying perpetrators when using CCTV images, how to create more identifiable facial composites, and the differences in accuracy between younger and older eyewitnesses. Providing in-depth discussion on the limitations of traditional lineups, eyewitness memory fallibility, and the complications that arise when using laboratory simulations, along with suggestions for new methods, this book will be an invaluable resource for researchers in eyewitness recognition, lawyers, players in the criminal justice system, members of innocence commissions, and researchers with interests in cognitive psychology.
