【摘要】：在心理学与医学交叉范畴内,心理应激与情绪反应、认知反应和行为反应密切相关,表征了个体对外界刺激的反应的复杂的心理过程。心理应激可以作为激励使人适应和应对各种挑战环境,而如果长期处于心理应激状态下,人的心身健康也要受到一定程度的损害,甚至会出现严重的心理健康问题。论文旨在定量描述和分析心理应激这一复杂过程,采用机理分析与数据驱动相结合的模型化方法,计算及识别人格特性、认知评价和心境特征等特征参数,建立起一个应激源作为输入,个体情绪反应作为输出的心理应激动态分层模型,并对模型的动态响应特征进行了仿真分析。人格特性对心理应激的影响体现在应激出现的时间和波动程度上,对其提出了一个基于聚类的方法,从调查问卷数据中进行识别;而认知评价特征影响了心理应激的恢复时问,提出了针对具体的应激源采用贝叶斯分类的方法计算认知评价参量。作为应用研究,将所建立的心理应激模型应用于大学生的心理应激反应当中,针对大学生群体常见的应激源,分析和评估其心理应激响应,获得的结论有助于在一定程度上指导对于大学生的心理应激的有效应对。
[Abstract]:In the cross-category of psychology and medicine, psychological stress is closely related to emotional response, cognitive response and behavioral response, which represents the complex psychological process of individual response to external stimuli. Psychological stress can be used as an incentive to make people adapt to and cope with all kinds of challenges, but if they are in the state of psychological stress for a long time, their psychosomatic health will be damaged to a certain extent, and even serious mental health problems will appear. The purpose of this paper is to quantitatively describe and analyze the complex process of psychological stress, and adopt a modeling method combining mechanism analysis and data drive to calculate and identify the characteristic parameters such as personality characteristics, cognitive evaluation and mood characteristics. A dynamic delamination model of psychological stress was established with stress source as input and individual emotional response as output. The dynamic response characteristics of the model were simulated and analyzed. The influence of personality characteristics on psychological stress is reflected in the time and fluctuation of stress. A clustering based method is proposed to identify the personality characteristics from the questionnaire data, while cognitive evaluation features affect the recovery of psychological stress. A Bayesian classification method is proposed to calculate the cognitive evaluation parameters for specific stressors. As an applied study, the established psychological stress model was applied to the psychological stress response of college students, and the common stressors of college students were analyzed and evaluated. The conclusions obtained are helpful to guide the effective coping of college students' psychological stress to some extent.
