This book provides a comprehensive, up-to-date discussion of contemporary debates at the interface between psychology and criminal law. The topics surveyed include critiques of eyewitness testimony; the jury; sentencing as a human process; the psychologist as expert witness; persuasion in the courtroom; detecting deception; and psychology and the police. Kapardis draws on sources from Europe, North America, and Australia to provide an expert investigation of the subjectivity and human fallibility inherent in our system of justice. He also provides suggestions for minimising undesirable influences on crucial judicial decision-making. International in its scope and broad-ranging in its research, this book is the authoritative work on psycho-legal enquiry for students and professionals in psychology, law, criminology, social work, and law enforcement.
