摘要:
测量大学生一天中认知疲劳的变化趋势,为促进大学生身心健康提供参考.方法 对33名备战考研的淮南师范学院大四学生进行智力测验和气质类型测验,在一天中10个不同的时间点上统一进行认知疲劳成绩的测定.结果 上午时段中,译码成绩最低为7:30(34.75±7.33),最高为11:20(51.90±10.56);下午时段中,译码成绩最低为18:20(46.75-±8.97),最高为16:20(53.60±9.50).在上午学习时间内(7:30-11:20),认知疲劳度逐渐降低;在下午学习时间内(14:20-18:20),认知疲劳度先低后高;高智商组在每一测试时段的译码测验成绩均高于低智商组,并且高智商组被试认知疲劳变化趋势相对于低智商组更为平缓;胆汁质组被试在每一测试时段的译码测验成绩均高于其他3组被试,多血质组一天之中波动幅度变化最为平缓,抑郁质组被试一天之中波动幅度变化最为显著.结论 认知疲劳高低水平起伏变化受自然时间点、智力水平、气质类型影响.
