| 目的：探讨考试应激对不同特质焦虑者注意稳定性的影响。方法：利用状态-特质焦虑问卷对参加大学生英语四级考试（CET-4）的某大学400名大学生进行初筛，从中随机抽取10名高特质焦虑学生和10名非高特质焦虑学生，分别进入高特质焦虑组和非高特质焦虑组。应用数字划消实验和事件相关电位测量其对照期（学期开始2周后，后3个月内无考试）和应激期（CET-4前2周至前1d）的注意力，进行统计分析。结果：（1）非高特质焦虑组的划对数高于高特质焦虑组（F=8．178，P=0．007）。（2）对照期高特质焦虑组的P300波幅及潜伏期与非高特质焦虑组均无差异（F分别为0．125和0．127，P分别为0．728和0．726）；应激期高特质焦虑组的P300波幅明显低于非高特质焦虑组（F=12．913，P=0．002），P300潜伏期明显长于非高特质焦虑组（F=16．952，P=0．001）。应激期非高特质焦虑组的P300潜伏期短于对照期（F=6．514，P=0．020）。结论：考试应激对不同特质焦虑者注意稳定性的影响不同。高特质焦虑者是应激管理的重点人群。[著者文摘] |

| Abstract: |
| Objective：To examine the influence of exam stress on the sustained attention of students with different levels of trait anxiety. Methods： With the State-Trait Anxiety Inventory （STAI）, 10 students with high trait anxiety （high trait anxiety group, H group） and 10 with non-high trait anxiety （non-high trait anxiety group, NH group） were randomly sampled from 400 students taking the coming College English Test-Band 4 （CET-4）. Their attention was measured with digit cancellation test and the event related potentials during the control phase （the period was chosen 2 weeks after the beginning of the semester and there was no examination in the following 3 months） and the stress phase （ from 2 weeks to 1 day before CET-4 examination）. Results： The right cancellation number of the NH group was higher than that of the H group（P=8. 178, P=0. 007）. During the control phase the P300 amplitude and latency were similar between the 2 groups （F= 0. 125, 0. 127, respectively; P= 0. 728, 0. 726, respectively）. During stress phase the P300 amplitude of the H group was significantly lower than that of the NH group（F=12. 913, P=0. 002）and the P300 latency of the H groups was longer than that of the NH group（P=16. 952, P=0. 001）. In NH group, the P300 latency in the stress phase was significantly shorter than that of the control phase （F= 6. 514,P=0. 020）. Conclusion： Exam stress has different influences on the sustained attention of people with different levels of trait anxiety, which suggests that people with high trait anxiety are the target population for stress management.[著者文摘] |
