【摘要】：進化適應(yīng)論的觀點認為道德厭惡是由核心厭惡進化發(fā)展而來的。核心厭惡情緒的產(chǎn)生,可以有效地制止個體進食有毒或腐爛的食物。隨著社會的發(fā)展,道德厭惡情緒逐步產(chǎn)生,對規(guī)范道德行為起著重要的作用。論文包括兩項研究,探討道德厭惡與核心厭惡對欺騙行為的影響及其自主神經(jīng)機制與大腦激活情況。研究一采用數(shù)學題矩陣任務(wù)考察道德厭惡和核心厭惡情緒對個體欺騙行為的影響,被試為45名在校大學生,實驗采用數(shù)學題矩陣任務(wù)考察被試的欺騙行為。研究二借助近紅外腦成像技術(shù)探查道德厭惡和核心厭惡情緒反應(yīng)的腦神經(jīng)活動,被試為20名在校大學生,用MP150型16通道生理信號記錄儀實時采集被試的皮膚電反應(yīng),指溫以及心率指標的同時,利用近紅外掃描儀記錄大腦激活水平。結(jié)果表明:(1)厭惡情緒類型對欺騙行為的影響存在顯著差異。核心厭惡情緒喚醒后,個體欺騙行為發(fā)生率顯著升高;道德厭惡情緒喚醒后,欺騙行為發(fā)生率與中性對照組無顯著差異。(2)道德厭惡與核心厭惡的生理反應(yīng)均表現(xiàn)為心率下降,指溫升高。(3)兩種厭惡情緒喚醒時大腦激活水平存在性別差異,女性在前額葉前部,背外側(cè)前額葉以及眶區(qū)等腦區(qū)激活水平顯著高于男性。
[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.
