خود ناتوان سازی، ارزیابی مورد انتظار و عملکرد: متناسب سازی مثبت و شدت سازی منفی

Abstract Three studies investigated the influence of social- and self-evaluative motives on self-handicapping and performance. In each study, efficacy expectancies were manipulated by varying the difficulty of a preliminary task, and social- and self-evaluation were manipulated orthogonally. In Study 1, participants who self-handicapped performed better than those who did not when a positive or negative evaluation was expected, in some conditions. In Study 2, we used a situationally imposed handicap and found that both social- and self-evaluation participants showed improved performance in the presence of the handicap. In Study 3, when a positive or negative evaluation was expected, high self-handicappers performed better after choosing to self-handicap, for both social- and self-evaluative motives. Little evidence of self-handicapping or effects on subsequent performance was found for low self-handicappers. No evidence was found for self-handicapping among participants who could not be evaluated. Discussion centers around motives to self-handicap and implications for subsequent performance.
