Subject areas included competency to stand trial, issues of psychological evidence, crisis intervention and hostage negotiation, and special problems of the patient as offender. Additional subject areas were juvenile delinquency prevention through use of scare tactics, violence and the family, and the media and crime. Speakers were both criminal justice professionals and researchers from educational institutions. Four presentations on competency to stand trial discussed handling of the released mental patient, clinical and ethical problems in psychiatric assessments, diagnosis versus description in competency issues, and psychological aspects of courtroom testimony. The discussion of issues of psychological evidence focused on vocal indications of psychological stress, hypnosis, and determination of malingering. Sessions on crisis intervention and hostage negotiation examined hostage negotiation teams' values and organization, dynamics of the victim responses to terror, and the Stockholm syndrome. Sessions on patients as offenders focused on psychotherapy in probation and parole, group treatment of delinquents, the violent patient in the community, sentencing discretion, and legal aspects of treatment. Discussions of delinquency prevention examined the Scared Straight programs and the theory of juvenile intervention. Presentations on violence and the family examined social stress and marital violence, characteristics of families prone to violence, and violent surrogate families. Presentations on media and crime discussed studies of pornography and violence against women, a field study of television viewing and aggressive behavior in preschool children, aggression in children after observing filmed aggression, and the relationship of adolescent aggression to television. Closing discussions focused on a neuropsychosocial perspective of persistent juvenile delinquency and criminal behavior. Figures, tables, and chapter reference lists are included.
