Abstract
Fifty-eight junior high school studens were divided into three groups and placed under supervisors of different supervisory types (P, M, or PM). Under the supervision of these adult supervisors, the studens were made to engage in a simple and repetitive task. During the course of the work, skin conductance and heart rate were monitored. Under P type supervision both GSR and HR increased, but under M type supervision GSR increased and HR rather decreased signficantly. Under PM type supervision GSR increased but HR did not change. A discussion was made on these physiological responses from the point of view of Lacey's environmental inake-rejection response patterns.
