为考察重要失败经历对高、低耐挫大学生挫折心理的影响，实验1操纵高、低耐挫大学生在非常重要和较重要任务上经历失败。结果发现，与较重要任务相比，在非常重要任务上失败后，大学生有更消极的情绪和更强的成功坚信程度；低耐挫大学生有更少的坚持意愿，高耐挫大学生有更多的坚持行为。实验2操纵高、低耐挫大学生在非常重要任务上经历连续失败。结果发现，高耐挫大学生的成功坚信程度在经历连续3次、4次失败时显著下降，坚持意愿在连续3次失败时显著下降。低耐挫大学生的情绪体验和成功坚信程度在经历连续3次、5次失败时显著下降；坚持意愿在经历连续2次、4次失败时显著下降。结果表明，任务重要程度影响高、低耐挫大学生的挫折心理；高、低耐挫大学生经历连续失败时的挫折心理变化趋势不同。

The current study aimed to investigate the effects of major failure on the frustration levels of undergraduates with high and low perseverance. In study 1, undergraduates with high and low perseverance were asked to complete tasks differing in importance. The results showed that undergraduates had more negative emotions and more confidence about their success when they experienced failure in the most important task. Undergraduates with low perseverance expressed less intention to persist, while undergraduates with high perseverance displayed more persistence when they experienced failure in the most important task. In study 2, undergraduates with high and low perseverance were asked to complete a task and experience consecutive failures. For undergraduates with high perseverance, the results showed that their confidence in success decreased significantly after experiencing three or four consecutive failures. Also, their intention to persist decreased significantly after experiencing three consecutive failures. For undergraduates with low perseverance, the results showed that their emotional experience and intention to persist decreased significantly after experiencing three or five consecutive failures. Also, their confidence in success decreased significantly when they experienced two or four consecutive failures. These results indicate that task importance affects the frustration levels of undergraduates with high and low perseverance. The frustration levels of undergraduates with high and low perseverance who experienced consecutive failures showed different trends.
