Abstract

This research examined whether there are differences in group decision making between senior leader groups and junior leader groups. Results revealed that senior leaders contributed more during the discussion than junior leaders, and groups with senior leaders performed better than the groups with junior leaders. In post-discussion activities group members noted that senior leaders were able to represent their groups better, and showed better leadership during discussion. On the other hand, the leader's age impacted differently depending on leader selection methods. For senior leaders, leaders randomly assigned were perceived to be more beneficial to groups. However for junior leaders, leaders systematically selected were perceived to represent their groups better and exhibit better leadership. The interaction between leader's age and leader selection seems to arise from a difference of leader's power bases.

본 연구는 리더의 나이에 따라 집단 의사 결정이 어떻게 달라지는지 알아보고자 하였다. 연구 결과, 나이 많은 리더가 나이 적은 리더에 비해 토론 중 발언 비율이 높았으며, 나이 많은 리더가 속한 집단의 결정 정확률이 더 높았다. 또한 리더의 나이가 많은 경우, 집단 구성원들은 리더의 집단 대표성과 발휘된 리더십을 더 높게 인식하고 있었다. 한편, 리더의 나이가 집단 의사 결정에 끼치는 영향은 리더 선출법에 따라 달라졌다. 리더의 나이가 적은 경우에는 체계적인 방법으로 선출된 리더 집단의 토론의 질이 높게 나타난 반면, 리더의 나이가 많은 경우에는 무작위로 선출된 리더 집단의 토론의 질이 높게 나타났다. 이와 같은 결과는 리더가 소유한 권력 기반의 차이에서 비롯된 것이라 추론할 수 있다.
