【摘要】：进化适应论的观点认为道德厌恶是由核心厌恶进化发展而来的。核心厌恶情绪的产生,可以有效地制止个体进食有毒或腐烂的食物。随着社会的发展,道德厌恶情绪逐步产生,对规范道德行为起着重要的作用。论文包括两项研究,探讨道德厌恶与核心厌恶对欺骗行为的影响及其自主神经机制与大脑激活情况。研究一采用数学题矩阵任务考察道德厌恶和核心厌恶情绪对个体欺骗行为的影响,被试为45名在校大学生,实验采用数学题矩阵任务考察被试的欺骗行为。研究二借助近红外脑成像技术探查道德厌恶和核心厌恶情绪反应的脑神经活动,被试为20名在校大学生,用MP150型16通道生理信号记录仪实时采集被试的皮肤电反应,指温以及心率指标的同时,利用近红外扫描仪记录大脑激活水平。结果表明:(1)厌恶情绪类型对欺骗行为的影响存在显著差异。核心厌恶情绪唤醒后,个体欺骗行为发生率显著升高;道德厌恶情绪唤醒后,欺骗行为发生率与中性对照组无显著差异。(2)道德厌恶与核心厌恶的生理反应均表现为心率下降,指温升高。(3)两种厌恶情绪唤醒时大脑激活水平存在性别差异,女性在前额叶前部,背外侧前额叶以及眶区等脑区激活水平显著高于男性。
[Abstract]:According to evolutionary adaptation theory, moral aversion develops from the evolution of core aversion. Core aversion can effectively prevent individuals from eating toxic or rotting food. With the development of society, moral aversion gradually emerges, which plays an important role in regulating moral behavior. The paper includes two studies to explore the effects of moral aversion and core aversion on deceptive behavior, autonomic nervous mechanism and brain activation. In the first study, the effects of moral aversion and core aversion on individual deceptive behavior were investigated by using the task of mathematical matrix. The subjects were 45 college students and the task of mathematical problem matrix was used to investigate the deceptive behavior of the subjects. The second study was to explore the neuroactivity of moral aversion and core aversion by using near infrared imaging technique. Twenty college students were enrolled in the study. The skin electrical responses were collected by MP150 16-channel physiological signal recorder in real time. At the same time, NIR scanner was used to record the brain activation level along with the index of finger temperature and heart rate. The results showed that: (1) there were significant differences in the influence of the type of aversion on cheating behavior. After arousal of core aversion, the incidence of individual deceptive behavior increased significantly. After arousal of moral aversion, the incidence of deceptive behavior was not significantly different from that of the neutral control group. (2) the physiological response of moral aversion and core aversion was the decrease of heart rate. (3) the activation level of brain in prefrontal lobe, dorsolateral prefrontal lobe and orbital area was significantly higher in female than in male.
