摘　　要：食物奖赏反应的增强和环境中食物线索的诱惑可能是肥胖流行的重要因素。研究发现社交媒体曝光是导致过度进食的风险因素,但其潜在影响机制还未见探究。本研究从社交媒体互动的新视角切入,第一部分从理论层面探究社交媒体互动反馈对肥胖者食物奖赏加工的影响机制;模拟社交媒体互动,利用ERP技术(研究1)、fMRI技术(研究2)探究社交媒体“点赞”与评论对肥胖者食物奖赏“想要”“喜欢”成分以及奖赏神经机制的影响。第二部分从应用层面,关注如何构建健全的社会网络文化体系,引导肥胖者建立健康饮食行为;训练社交媒体行为,利用ERP技术(研究3)、fMRI技术(研究4)考察社交媒体互动行为训练对肥胖者健康食物“想要”“喜欢”以及奖赏神经机制的影响。本研究进一步从社交媒体互动的视角丰富了食物奖赏理论,同时为健全公共文化服务体系,引导健康饮食提出干预策略。Enhanced food reward responses and the lure of food cues in the environment may be important contributors to the obesity epidemic.Social media exposure has been found to be a risk factor for overeating,but the underlying mechanisms of influence have not been explored.In the first part of this research,we examined the impact of social media interaction feedback on food reward processing in obese people from a theoretical perspective;we simulated social media interactions and utilized ERP technology(Study 1)and fMRI technology(Study 2)to investigate the influence of social media“likes”and comments on food reward processing in obese people,and to examine the influence of social media“likes”and comments on food reward processing in obese people,and to investigate the influence of social media“likes”and comments on food reward processing in obese people.The effects of social media“likes”and comments on the“wanting”and“liking”components of food reward and the neural mechanisms of reward in obese individuals will be investigated using ERP(Study 1)and fMRI(Study 2)techniques.In the second part,from the application level,we focus on how to build a sound social network culture system to guide obese people to establish healthy dietary behaviors;train social media“liking”behaviors,and examine the effects of social media interactive behavior training on healthy food“want”and“like”components and reward neural mechanisms in obese people by using the ERP technology(Study 3)and the fMRI technology(Study 4).The effects of social media interactive behavior training on the neural mechanisms of“wanting”,“liking”,and rewarding in obese individuals were investigated using ERP(Study 3)and fMRI(Study 4).This research further enriches the theory of food reward from the perspective of social media interaction,it also proposes intervention strategies for a sound public cultural service system to guide healthy eating.
