Abstract
PM-Sensitivity Training developed by Misumi (1972) was conducted for 60 nursing school teachers to improve their leadership ability. The trainee were divided into 10 groups by 6 members and discussed the case of post problem for 90 minutes. After that, they rated the leadership behavior (the task performance behavior and the group maintenance behavior) of themselves and of the co-members of each group during the discussion. Before the next case discussion, they were informed of the cognitive discrepancy between self-perception (ratings by themselves) and perceived-self (ratings by the co-members of each group) concerning their leadership behavior. The Perception Types (Self-Perception Valued Type; Perceived-Self Valued Type) were decided by asking them whether they valued self-perception or perceived-self. The case discussion, mutual ratings, and feedback of the discrepancy were conducted four times (the first session-the fourth session).
The main results of this study were as follows:
1) As the session acumulated, the discrepancy between self-perception and perceived-self concerning their leadership behavior had significantly decreased.
2) The number of the Perceived-Self Valued Type (29 persons) was significantly more than that of the Self-Perception Valued Type (11 persons).
3) In the process of reducing the cognitive discrepancy, the Self-Perception Valued Type tried to use the strategy that made perceived-self contiguous to self-perception (that made perceived-self change by changing their own leadership behaviorChanging Behavior Strategy) more than the Perceived-Self Valued Type. The Perceived-Self Valued Type tried to use the strategy that made self-perception contiguous to perceived-self (that changed self-perception-Changing Perception Strategy) more than Self-Perception Valued Type.
4) In the process of reducing the cognitive discrepancy, in general, Changing Perception Strategy was significantly used more than Changing Behavior Strategy.
