Sixty Ss were observed in groups of six in a free-play situation under both density conditions. Results showed that there was significantly less aggression and less social interaction in the high-density condition than in the low-dcnsity condition. Thcrc was a significant Density X Sex effect o n aggression and signficant main effects of sex on aggression, nurturance, number of interruptions, and number of children interacted with. Several complexities in researching and explaining the effects of density on behaviors are discussed. |
