In this research, in order to get some ideas regarding the activity of communicating, I investigated what differences occur in the communication among homogeneous groups and heterogeneous groups. As a result of this research, the following four points became clear, and I got closer to understanding the makeup of groups in the activity of communicating. 1 ) In a homogeneous group which consisted of "superiors," the members all tended to agree on the same scientifically correct conclusions, but because they omitted explanatory comments, sufficient communication did not materialige. 2 ) In a homogeneous group which consisted of "inferiors," even if the communication were advancing on a mistaken premise, the function which corrects such mistakes did not operate, and general understanding was not deepened. 3 ) The ideas of superiors in the heterogeneous group were sometimes confused by the remarks of inferiors. 4 ) Communication in the heterogeneous group was fruitful, and, especially for the inferiors in the group, there was effective communication which deepened general understanding.
