THE DISCUSSION IS IN THE FORM OF TESTIMONY PRESENTED BEFORE A COMMITTEE OF THE CANADIAN SENATE. THE WITNESS DISCUSSES HIS STUDIES OF THE EFFECTS OF EARLY EXPERIENCES ON BRAIN DEVELOPMENT AND BEHAVIOR, INCLUDING CROSS-CULTURAL STUDIES INDICATING A RELATIONSHIP BETWEEN DEPRIVATION OF PHYSICAL AFFECTION AND NURTURANCE IN THE PARENT-CHILD RELATIONSHIP AND PHYSICAL VIOLENCE. THESE STUDIES LED TO THE CONCLUSION THAT FAILURE OF NURTURANCE IN HUMAN RELATIONSHIPS, BEGINNING WITH THE PARENT-CHILD RELATIONSHIP, IS THE PRINCIPAL FACTOR IN THE DEVELOPMENT OF ALIENATION, PSYCHOPATHY, VIOLENCE, AND AGGRESSION. THE BULK OF THE TESTIMONY CONSISTS OF THE WITNESS' COMMENTS ACCOMPANYING FILM AND SLIDE PRESENTATIONS IN WHICH THE FINDINGS OF EXPERIMENTAL (ANIMAL) AND CROSS-CULTURAL STUDIES ON THE ORIGINS OF HUMAN VIOLENCE ARE ILLUSTRATED. THE WITNESS ALSO RESPONDS TO QUESTIONS POSED BY COMMITTEE MEMBERS. --IN ENGLISH AND FRENCH. (LKM)
