An aggression machine III. The stability of aggressive and nonaggressive patterns of behaviour

PitkÄnen, L. The stability of aggressive and non-agressive patterns of behaviour. Scand. Psychol., 1973, 14, 75–77.-Six extreme groups (overtly aggressive, aggressive-anxious, anxious, controlled extraverts, balanced controlled, and controlled introverts) had been composed on the basis of peer ratings. The differences between the groups were describable in terms of a two-dimensional model including the main dimensions "number of overt responses" and "control of behaviour". Independent teacher ratings after an interval of one year showed that the individual patterns of behaviour adopted for coping with thwarting situations were maintained in spite of the change of class environment.
