50. Group ways of channelizing aggression (28:58)

Date:
1958
Summary:
The methods of directing and using aggression in children are demonstrated in studies of the Americans of the continental United States, the Kwoma of New Guinea, and the Alorese of the Dutch East Indies. We move from the creation of frustration in children through the expression of aggressive responses to the various ways the aggressive responses are directed and utilized. Dr. Bullock’s narration is closely linked to dance action and original musical effects. The types of stimuli that frustrate children are explained. As each example is followed to its logical end of aggressive behavior, one can understand the hit-and-run tactics of the Kwoma, the competitive spirit of the American, and the inferior and helpless feeling of the Alorese. The battle scenes presented at the end of the Kwoma and Alorese groups throw our concept of war into a new mental perspective.
