Book excerpt: 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.
