Understanding Eyewitness Memory

An essential overview of how perception and memory affect eyewitness testimony In 1981, sixteen-year-old Michael Williams was convicted on charges of aggravated rape based on the victim’s eyewitness testimony. No other evidence was found linking him to the attack. After nearly twenty-four years, Williams was released after three separate DNA analyses proved his innocence. The victim still maintains that Williams was the culprit. This heartbreaking case is but one example of eyewitness error. In Understanding Eyewitness Memory, Sean M. Lane and Kate A. Houston delve into the science of eyewitness memory. They examine a number of important topics, from basic research on perception and memory to the implications of this research on the quality and accuracy of eyewitness evidence. The volume answers questions such as: How do we remember and describe people we’ve encountered? What is the nature of false and genuine memories? How do emotional arousal and stress affect what we remember? Understanding Eyewitness Memory offers a brilliant overview of how memory and psychology affect eyewitness testimony, where quality and accuracy can mean the difference between wrongful imprisonment and true justice.

"This book examines basic behavioral and neuroscientific research on perception and memory and its relevance for understanding how errors might occur when remembering complex events such as those experienced by eyewitnesses"--

The organization of the first Society for Applied Research in Memory and Cognition (SARMAC) conference centered around two specifically identifiable research topics -- autobiographical memory and eyewitness memory. These two areas -- long-time staples on the menu of investigators of memory in more natural settings -- differ on a variety of dimensions, perhaps most notably on their specific goals for scientific inquiry and application. For many questions about memory and cognition that are of interest to scientific psychology, there have been historical as well as rather arbitrary reasons for their assignment to the autobiographical or eyewitness memory fields. Perhaps as a result of differing historical orientations, the first volume's seven autobiographical memory chapters focus upon the qualities or types of recall from research participants, whereas the seven chapters in the eyewitness memory volume generally focus upon the quantity (a concern for completeness) and accuracy of recall. This interest in the ultimate end-product and its application within the legal process in general encourages eyewitness memory investigators to modify their testing procedures continually in an attempt to gain even more information from participants about an event. Indeed, several of the eyewitness memory chapters reflect such attempts. Beyond the specific contributions of each chapter to the literature on autobiographical and eyewitness memory, the editors hope that the reader will come away with some general observations: * the autobiographical and eyewitness memory fields are thriving; * these two fields are likely to remain center stage in the further investigation of memory in natural contexts; * although the autobiographical and eyewitness memory chapters have been segregated in these two volumes, the separation is often more arbitrary than real and connections between the two areas abound; * the two research traditions are entirely mindful of fundamental laboratory methods, research, and theory -- sometimes drawing their research inspirations from that quarter; and * the two fields -- though driven largely by everyday memory concerns -- can contribute to a more basic understanding of memory at both an empirical and a theoretical level.

By shedding light on the many factors that can intervene and create inaccurate testimony, Elizabeth Loftus illustrates how memory can be radically altered by the way an eyewitness is questioned, and how new memories can be implanted and old ones changed in subtle ways.

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.
