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.
Explains the nature and importance of population genetics. Derives the Hardy-Weinberg equilibrium principle for Mendelian (cross-breeding) populations. Points out that though the Hardy-Weinberg law produces a static gene pool when it applies, mutation, selection, random genetic drift, and migration upset this equilibrium and cause gene frequencies to shift-these factors being, therefore, the principal causes of evolution.
