This book is based on the substantial influence of Dr. Lawrence S. Wrightsman, Jr. It is a means to honor his many contributions to the field of psychology and law and allow for current scholars to demonstrate the significance (both theoretical and professional) of an outstanding researcher, teacher, colleague, and friend. By virtue of his conducting research on so many of the core topics in the discipline, the book provides an overview of the current status of the field of psychology and law and places the contributions of Wrightsman within that field. The field of psychology and the law turned 100 years old in 2008—that year marked the centennial of the book by Hugo Münsterberg, titled On the Witness Stand, which contained remarkably prescient chapters on many contemporary topics, including eyewitness accuracy, confessions, hypnosis, and criminal psychology (now called forensic psychology; for a contemporary assessment of Münsterberg’s work, see Bornstein & Meissner, 2008). That book is honored in the title, since it is also the title of two co-edited volumes by Lawrence S. Wrightsman. This book is meant to highlight the contributions of Lawrence S. Wrightsman, who has produced some 45 books on psychology and law, including his landmark textbook Psychology and the Legal System, over a nearly 50-year career. The book is designed to stand alone as an integrated digest of the various ways in which psychology informs legal practice and legal outcomes.
