情绪对低感觉寻求者安全行为决策的影响:来自ERPs的证据

Effects of emotion on safety behavior decision-making of low sensation seekers:evidence from ERPs

为从神经层面深究不同偶然情绪对低感觉寻求者的不安全行为决策过程的影响作用,采用事件相关电位(ERPs)技术进行试验研究。使用中国版大学生感觉寻求问卷筛选低感觉寻求者和中感觉寻求者(对照组)。采用视频片段作为情绪刺激材料在试验前诱发正性和负性情绪,并设置风险情景任务进行风险决策试验。结果表明:不考虑情绪变量时,低感觉寻求组与感觉寻求对照组在安全行为决策上无显著差异;正性情绪下,低感觉寻求个体保持风险规避倾向;负性情绪下,在行为表现上,低感觉寻求者更倾向作出不安全行为决策;负性情绪下,在ERPs成分上,低感觉寻求者诱发的晚期正成分(LPP)潜伏期更晚,表明负性情绪的干扰导致个体在风险分类与评价时难度增大,故此从神经层面解释其外在行为表现的内在原因。总之,情绪在感觉寻求影响安全行为决策过程中产生调节作用。

To investigate the effects of different incidental emotions on low sensation seekers'unsafe behavior decision-making process from a neural level,ERPs technique was used.The Chinese version of the Sensation Seeking Questionnaire for College Students was used to select low and medium sensation seekers(control group).Then,video clips were used as emotional stimulus materials to induce positive and negative emotions before the experiment,and a risk scenario task was set to perform risk decision-making experiments.The results indicated that when the emotional stimulus variable was not considered,there was no significant difference in safe behavior decision-making between the low sensation-seeking and the control groups.Under positive emotion,low sensation seekers maintained risk aversion.However,low sensation seekers were more likely to make unsafe behavior decisions regarding behavioral performance under negative emotion.Under negative emotion,the latency of LPP induced by low sensation seekers was delayed,indicating that the interference of negative emotion made it more difficult for individuals to classify and evaluate risks.Therefore,the intrinsic reasons for their external behavioral performance can be explained from a neural level.Therefore,emotions play a moderating role in the process of sensation seeking affecting safe behavior decision-making.
