摘要
目的:通过实验方法探讨A型和B型人格男性对脑力任务的主观负荷评价的差异。方法:具有A型和B型人格的男性被试各40名做2项脑力任务:任务1为简单计算;任务2为Sternberg记忆搜索任务,每项任务持续5分钟。然后被试使用3个主观评价技术:库柏-哈柏修正法(MCH)、主观负荷评估技术(SWAT)和NASA任务负荷指数量表(NASA-TLX)来分别判断2项任务的脑力负荷大小。结果:A、B2组被试在两项脑力任务中,在具有同等的执行绩效情况下,具有A型人格男性的3个脑力负荷主观量表得分除MCH的任务1外均高于具有B型人格的男性(MCH任务1:6.5±0.5/5.9±0.5,t=1.67,P=0.083;任务2:7.3±0.5/6.3±0.4,t=2.72,P=0.024;SWAT任务1:75.3±5.8/58.2±5.3,t=5.04,P<0.001;任务2:68.8±6.4/59.1±6.6,t=2.75,P=0.022;NASA-TLX任务1总分64.8±6.7/46.2±7.1,t=3.15,P=0.014;任务2总分:58.8±4.7/45.6±5.7,t=3.36,P=0.009)。结论:A型人格男性对脑力任务的主观负荷评价较高。
Objective： The purpose of the present study was to investigate the subjective mental workload in Type A and Type B men during mental tasks. Methods： Forty Type A and 40 Type B men performed two tasks individually and both tasks took for 5 min. The tasks contained a simple mathematical processing one and a Sternberg memory search one. After performing the two tasks, subjects rated their subjective workload by three subjective techniques： the Modified Cooper-Harper Scale （MCH） , the Subjective Workload Assessment Technique （SWAT）, and the NASA Task Load Index （ TASA-TLX ） . Results： The trend was shown that for both tasks, under similar task performance, Type A men had higher scores than Type B men measured by MCH （Task 1：6.5±0.5/5.9 ±0.5, t = 1.67, P=0.083; Task2： 7.3±0.5/6.3±0.4, t=2.72, P =0.024, SWAT（Task 1： T=5.037, P〈0.001; Task2： T=2.746, P=0.022）, and NASA-TLX （Task 1 total score： 64.8 ±6.7/46.2 ±7.1, t=3.15, P= 0.014, Task2 total score： 58.8 ±4.7/45.6 ±5.7, t=3.36, P=0.009） . Conclusion： Type A men feel a greater subjective mental workload as compared with Type B men during mental tasks.
