社交媒体互动反馈对食物奖赏加工的影响机制
The effect of feedback from social media interactions on food reward processing and its mechanisms
摘要
Abstract
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.关键词
