【摘要】：心理学界和医学界已经对老年人日常认知的影响因素进行了广泛的研究，然而，这些研究通常采用调查和测量的方法，结果很难从根本上说明变量之间的关系。与以往研究不同，本研究采用实验研究的方法，讨论了知觉压力对老年人日常认知的影响。实验一用血压作为老年人压力唤起的生物指标，采用血压仪记录被试的血压值。通过对被试血压基线值与实验控制下血压值的比较，结果发现实验组和对照组的血压变化存在显著差异，证明了实验控制的有效性。实验二旨在探讨知觉压力对老年人日常认知的影响。实验采用知觉压力量表把被试区分为高知觉压力组和低知觉压力组，随后随机抽取高、低知觉压力被试各15名，分别组成高压力情景组和低压力情景组。两组被试分别在高压情境下和低压情境下完成实验任务，结果发现：（1）老年人的知觉压力不存在显著的性别差异。（2）知觉压力对老年人日常认知的影响显著，，不同知觉压力者的日常认知能力差异显著。低知觉压力老年人较高知觉压力老年人，他们的日常认知能力更好，尤其在低压力情境下，表现尤为突出。
[Abstract]:Psychological and medical circles have carried out extensive research on the influencing factors of the daily cognition of the elderly. However, these studies usually use the methods of investigation and measurement, and the results are very difficult to explain the relationship between variables fundamentally. In contrast to previous studies, the effects of perceptual stress on the daily cognition of the elderly were investigated by using an experimental method. In experiment 1, blood pressure was used as a biological index of stress arousal in the elderly, and blood pressure was recorded by blood pressure meter. By comparing the baseline value of blood pressure between the subjects and the blood pressure under experimental control, it was found that there were significant differences in blood pressure between the experimental group and the control group, which proved the effectiveness of the experimental control. Experiment two aims to explore the effect of perceptual stress on the daily cognition of the elderly. The subjects were divided into high perceptual stress group and low perceptual stress group with perceptual stress scale. Then 15 subjects with high and low perceptual stress were randomly selected to form high stress situation group and low pressure situation group respectively. The two groups of subjects completed the task under high pressure and low pressure, respectively. The results showed that: (1) there was no significant gender difference in perceptual stress in the elderly. 2) the influence of perceptual stress on the daily cognition of the elderly was significant, and the daily cognitive ability of the patients with different perceptual stress was significantly different. The elderly with low perceptual stress had better daily cognitive ability, especially in low stress situations.
