Abstract

During three years, the psychological-social development was observed in a group of 218 school pupils, aged 10-15 years, attending sport and control classes. Basing on the aggression scale of the A.H. Buss and A. Durkee Hostility-Guilt Inventory, the questionnaire on neuroticism Jaki jestes (What Are You Like?) by E. Skrzypek and M. Choynowski and the interview method, it was concluded that with age, there was an increase of general aggressiveness, strongly positively correlated with neuroticism, in both groups of pupils. However increase of aggressive behaviour was greater and statistically significant in a group of non-sport boys. In sport-active boys significant decrease of neuroticism level and less aggressiveness was observed. These dependence did not appear in observing girls. Concomitantly girls from the control groups showed a significant drop in the index of guilt-feeling. It might be postulated that increased physical activity influenced the regulation of aggressive behaviour connected with neuroticism in the group of boys from sport classes, producing a favorable effect in the process of their social development.
