Aim: This thesis discusses the relationship between college students' boredom tendency and attribution style as well as achievement motivation. Method: The author uses scale assessment on college students of boredom tendency scale, the inner-control scale, internality-powerful others scale and chance scale draw up by Leveson, as well as achievement motivation scale. Results: 1) There is no significant differences in sex on the boredom tendency of college students; in grade level, a comparatively significant difference exists between the total scores of tension, binding force and boredom tendency. 2) The total score of boredom tendency has significant negative correlation with that of achievement motivation (r = -0.509, p<0.01), has significant negative correlation with the success-wish dimension (r = -0.284, p<0.05), has significant positive correlation with the failure-fear dimension (r = 0.505, p<0.01), has negative correlation with the inner-control dimension (r = -0.133, p<0.05), has positive correlation with the chance dimension (r = 0.406, p<0.01), and has significant positive correlation with internality-powerful others dimension (r = 0.373, p<0.01). 3) The boredom tendency has mediating effect on achievement motivation and attribution style. Conclusion: The boredom tendency is closely related to the attribution style and achievement motivation, and plays a partial mediating role in the relationship between attribution style and achievement motivation.
