Psychology, Law and Eyewitness Testimony Peter B. Ainsworth, University of Manchester, UK Before giving evidence, witnesses have to swear to tell 'the truth, the whole truth and nothing but the truth'. Given current knowledge about human perception and memory, it is unlikely that witnesses will be able to keep this promise. Many professionals within the criminal justice and legal system are involved in recording and assessing eyewitness testimony, sometimes with unrealistic expectations of the ability of eyewitnesses to provide accurate and objective testimony: they, and students of psychology, law and criminology, will welcome this up-to-date, accessible survey of the concepts and research which now inform our knowledge of this field. Peter Ainsworth, an experienced lecturer and researcher, has written this book in a style suitable for non-specialists, and focuses on how and why witnesses make mistakes, how psychologists can help, and how legal procedures can be improved (for instance, by reducing the pressure on witnesses to guess). The text is authoritative, backed by references to key research, and well illustrated by examples of how psychology and law are interlinked in the study of eyewitness behaviour. "From some books you take new knowledge. Some books consolidate knowledge by clear writing. Occasionally, as in this book, you get both. Peter Ainsworth has done his readers a favour by presenting complex material simply yet succinctly. I hope the book enjoys the wide professional readership which it merits." Ken Pease, OBE, Professor of Criminology, University of Huddersfield, UK

Examines traditional safeguards against mistaken 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.

From the initial investigation of a crime to the sentencing of an offender, many everyday practices within the criminal justice system involve complex psychological processes. This volume analyzes the processes involved in such tasks as interviewing witnesses, detecting deception, and eliciting eyewitness reports and identification from adults and children. Factors that influence decision making by jurors and judges are examined as well. Throughout, findings from experimental research are translated into clear recommendations for improving the quality of evidence and the fairness of investigative and legal proceedings. The book also addresses salient methodological questions and identifies key directions for future investigation.
