摘　　要：利用心理生理实验法,通过将情绪抑制操作引入最后通牒博弈实验范式,探讨负性情绪抑制的主观情绪体验、生理反应及其对社会决策行为的影响。以40名大学生为被试,采用MP150型16导生理记录仪记录皮肤电反应和心率。实验为2(组别:情绪抑制组、自然观看组)×2(性别:男、女)×2(博弈对手:人、计算机)×4(分配方案:$5:$5、$7:$3、$8:$2、$9:$1)的混合设计,其中组别和性别为被试间因素,博弈对手和分配方案为被试内因素。结果发现:(1)对负性情绪进行抑制没有减少被试相应的主观体验,情绪抑制使皮肤电反应性增强;(2)负性情绪抑制的主观体验和生理反应不存在性别差异;(3)在面对不公平的分配方案时,情绪抑制组被试比自然观看组更倾向于拒绝接受。结果表明在最后通牒博弈中,情绪抑制影响回应者的行为反应,使他们更倾向于做出不理智的决策。Emotion suppression is a form of emotion regulation defined as the conscious inhibition of emotionally expressive behavior while emotionally aroused. Previous research has shown that inhibiting emotionally expressive behavior leads to depletion of self-regulatory capacities and increased sympathetic activation of the cardiovascular system. Evidence from decision-making research has indicated that the cognitive-affective component was modulated by the attributes of options when making choice. This process was monitored by the individual and required an effort of self-regulation. Drawing from a limited-resource model of self-regulation, we predicted that emotion suppression would impact the subsequent decision making task due to the depletion of the self-regulatory capacity. The study was designed to investigate the effects of emotion suppression and its influence on the behavioral responses of respondents in the ultimatum game, using methods of psycho-physiological experiments. Participants were 20 female and 20 male college students. Ten negative pictures were presented to all the participants. Half of them were instructed to suppress their emotions and the other half simply watch the pictures, and then all the participants were instructed to play as the responders in the ultimatum game presented on the video monitor. Physiological measures were collected continuously throughout the whole procedure. Emotional states before and after watching the pictures were assessed by using a self-report inventory, which contained 5 emotional states： amusement, anger, disgust, fear and sadness. The experimental design was a 2x2x4 mixed factorial, in which group condition （no-suppression, suppression） varied between subjects, and game rival （human, computer） as well as money proposals （￥ 5： ￥ 5, ￥7： ￥ 3,￥ 8： ￥ 2, ￥ 9： ￥ 1） varied within subjects. The results showed that： （1） the Repeated Measure ANOVA for the self-report variables did not reveal any effects with respect to group con
