| 中文摘要 | The sense of agency refers to the feeling of control over one's own movements and external environment that arises during active movement. It is a fundamental characteristic of human mental activity and has received increasing attention from researchers due to its prevalence in daily life. Previous studies have shown that the sense of agency is influenced by many factors, especially the emotional state in which the subject is living. General emotional arousal can enhance the sense of agency, while strong emotional arousal such as anger, fear, and sexual arousal can diminish the sense of agency. Psychosocial stress is one of the common stressors in our lives and is categorized into acute psychosocial stress and chronic psychosocial stress. Previous studies have demonstrated that chronic psychosocial stress has adverse effects on our health, while the effects of acute psychosocial stress on the sense of agency are unknown. The Trier Social Stress Test is one of the most valid and commonly used laboratory tasks to study human stress responses. It consists of a 5-minute preparation, a 5-minute public presentation, and a 5-minute mental arithmetic task. Therefore, the main purpose of this study was to assess the effect of acute psychosocial stress on the perception of the sense of agency through the Trier Social Stress Test. The methodology of the study involved comparing the changes in subjective indicators and objective physiological indicators produced by the two groups before and after the Trier Social Stress Test, with the groups randomized. We used the Self-Assessment Model scale as a subjective indicator and heart rate, electrodermal activity, and salivary cortisol levels as objective physiological indicators. There are two approaches to measuring the sense of agency: explicitly and implicitly. The four main findings of this study are as follows. First, using an implicit measure of the sense of agency, the experimental group's temporal binding scores differed significantly between the pre-test and the post-test, suggesting that acute psychosocial stress led to a decrease in the sense of agency. However, the results of the extraneous and implicit measures were not consistent. Second, analyses of the temporal estimation results found that both implicit and explicit measures indicated that the interval between the behavior and the subsequent outcome was subjectively compressed to a greater degree and the sense of agency was greater in the voluntary condition than in the involuntary condition. Third, the Trier Social Stress Test was able to elicit consistent stress responses at both the physiological and psychological levels, and the experimental group's scores on subjective ratings of emotional arousal, as well as changes in physiological indices including heart rate, electrodermal activity, and salivary cortisol, were significantly different from those of the control group. Changing values of salivary cortisol significantly predicted the magnitude of the temporal binding effect. Fourth, a correlation analysis of all subjects' scores on the Trait Anxiety Inventory and the sense of agency Inventory revealed that the Trait Anxiety Inventory score (T-AI) was significantly negatively correlated with the positive sense of agency (SoPA) scores, whereas the Trait Anxiety Inventory score (T-AI) was significantly positively correlated with the negative sense of agency (SoNA) scores. This suggests that there may be a potential link between trait anxiety and sense of agency and that the effect of trait anxiety on sense of agency is negative. Taken together, these results suggest that acute psychosocial stress leads to strong emotional arousal, a significant reduction in the temporal binding effect, and a diminished sense of agency. The results of this study have important reference value for our understanding of the mechanisms by which psychosocial stress affects human health and the changes in the sense of agency in social situations. |
| 英文摘要 | 主动控制感是在主动动作过程中产生的控制自身动作，进而控制外界事物和环境的一种主观体验。主动控制感是人类心理活动的一个基本特征，因其在生活中的重要性，近年来有关主动控制感的研究与日俱增。既往的研究表明，主动控制感受到许多因素的影响，尤其是主体所处的情绪状态，如一般的情绪唤起可以增强主动控制感，而强烈的情绪唤起如愤怒，恐惧，性唤起状态等则会使主动控制感减弱。社会心理应激是我们生活中常见的应激源之一，它分为急性社会心理应激和慢性社会心理应激。既往研究证实了慢性社会心理应激对我们的健康产生不利的影响，而急性社会心理应激所导致的社交焦虑状态对主动控制感的影响尚不清楚。特里尔社会应激测试是研究人类应激反应最有效和最常用的实验室任务之一，包括 5min 准备，5min 公开演讲和 5min 心算任务。本研究的主要目的是通过特里尔社会应激测试评估急性社会心理应激对主动控制感的影响。研究方法是以健康的在校大学生为研究对象，通过随机分组的方法，对比两组在特里尔社会应激测试的前后所产生的主观指标和客观生理指标的变化，我们选取了情绪状态的自我评估量表为主观指标，心率，皮肤电活动和唾液皮质醇水平为客观生理指标。主动控制感的测量包括外显测量和内隐测量，主动动作的时间压缩效应是内隐测量的一种常用的方式。我们通过时间估计任务同时对主动控制感进行外显测量和内隐测量，以此来检验急性社会心理应激对主动控制感的影响。 本研究的主要发现有以下四点。第一，通过对主动控制感的内隐测量，实验 组的时间绑定得分在前测和后测之间存在显著差异，表明急性社会心理应激导致 了主动控制感的下降。而外显测量和内隐测量的结果出现了分离的现象。 第二，对于时间估计结果的分析发现，无论是内隐测量还是外显测量都表明， 在主动动作条件下，动作和随后的结果之间的间隔在主观上比在被动条件下被压 缩得更大，主动控制感更强。 第三，特里尔社会应激测试能够在生理和心理水平导致一致的应激反应，实 验组的主观评分中的情绪唤起度的得分以及生理指标的变化，包括心率，皮肤电 导水平，皮肤电导反应以及唾液皮质醇，都与控制组存在显著差异。唾液皮质醇 的变化值能够显著预测时间压缩效应的大小。 第四，通过对所有被试特质焦虑量表和主动控制感量表得分进行相关分析发 现，特质焦虑量表得分（T-AI）与正性的主动控制感（SoPA）得分呈显著负相 关，而特质焦虑量表得分（T-AI）与负性的主动控制感（SoNA）得分呈显著正 相关。表明，特质焦虑与主动控制感之间可能存在潜在联系，而且特质焦虑对主动控制感的影响是负性。 综合以上结果表明，急性社会心理应激会导致强烈的情绪唤起，时间压缩效应显著减弱，主动控制感减弱。本研究的结果对我们理解社会心理应激影响人类 健康的机制以及社交情境下的主动控制感的变化有重要的参考价值。 |
