In the past, a considerable amount of research has been conducted into the effects of congruence between information display and task requirement on decision-making performance. The theoretical base for these works is the cost-benefit framework, which explains that the effort of decision makers will depend on the level of accuracy expected and the cost of the strategy employed to complete the task. In this research, the factor of self-efficacy is integrated into the cost-benefit framework for predicting decision making performance. An experiment was designed with two factors, display congruence and self-efficacy. The display congruence is a within-subject factor with 2 levels, high congruence and low congruence; the self-efficacy is a between-subject factor with 2 levels, high versus low. Subjects¡¦ eye movements were also tracked with an apparatus, eye tracker.
A total of 30 subjects participated in the experiment and 20 were found to be valid based on an analysis of the eye movement data. These subjects were divided into high and low self-efficacy groups according to their scores of self-efficacy measurement. The results show that when the congruence is low, subjects spent significantly longer decision time and changed information acquisition direction than they do when the congruence is high, although there was no difference in decision accuracy between these two conditions. Self-efficacy is found to significantly predict goal commitment, intensity of effort, and decision accuracy. In addition, when subjects moved from the situation of high congruence display to the low congruence one, high self-efficacy subjects were found to increase their level of effort more than low self-efficacy subjects.
