时间取向与乐观偏差的关系:乐观的中介作用

The relationship between time perspective and optimism bias:the mediating effect of optimism

采用津巴多时间取向量表、生活定向问卷修订版、生活事件量表对870名大学生被试进行调查。结果显示:时间取向与气质性乐观、乐观偏差三者之间存在显著的相关关系;气质性乐观在消极过去取向、宿命现在取向与消极将来事件可能性判断之间呈正向的部分中介作用,在宿命现在取向与积极将来事件可能性判断之间呈负向的部分中介作用,在积极过去取向、未来取向与消极将来事件可能性判断之间呈负向的部分中介作用,在积极过去取向、未来取向与积极将来事件可能性判断之间呈正向的部分中介作用,在消极过去取向与积极将来事件可能性判断之间起完全中介作用。结论:时间取向(除了消极过去取向)直接影响乐观偏差,也可以通过气质性乐观间接影响乐观偏差。

This study aimed to examine the relationship between time perspective and optimism bias,and the mediating effect of optimism.Zimbardo Time Perspective Inventory,Life Orientation Test-Revised and Life Event Scale were used to investigate 870 college students.The results show that optimism has a significant correlation with time perspective and optimistic bias.Optimism has a positive partially mediating role between past negative perspective,fatalistic present perspective and possibility judgment of negative events,and a negative partially mediating role between fatalistic present perspective and positive future events possibility judgment.Optimism has a negative partially mediating role between positive past perspective,future perspective and possibility judgment of negative future events,a positive partially mediating role between positive past perspective,future perspective and possibility judgment of positive future events.Optimism plays a completely mediating role in the relationship between negative past orientation and possibility judgment of positive future events.The results indicates that time perspective(in addition to negative past perspective)directly affects optimism bias,but also indirectly affects optimism bias through optimism.
