集團成層構造の研究

In this report we consider the group stratification and its stability from a few points of view. By using a large number of primary school boys who have been typical leaders and followers in school life, we organized the following three combination. 1) a leader and a follower. 2) a leader and a leader. 3) a follower and a follower.
And then these combinations were placed in the following three experimental conditions.
1) Group members were placed in a spontaneous situation.
2) Group members were given an adult leader's pressure.
3) The insight which each group member has had to that situation was changed.
In these conditions we studied the processes of change in the type of group stratification and the degree of stability of member relation in the group stratification.
The results of these experiments are as follows :
1. The type of groupstratification is determined sometimes by the insight which each member has on the situation or at othertimes by the barrier which is constituted by an outside factor. It is felt that the type of group stratification may be represented by the free movement region which each member has in the situation in relation to other members.
2. The degree of stability of group member relation in group stratification is influenced by the degree of definition of the boundaries of the free movement region which each member has, it is believed.
3. But these cencepts free movement region and the degree of definition of boundary, have not been defind operationally. Therefore we will consider these concepts experimentally in the near future.
