摘　　要：肥胖问题给我国国民身心健康带来了严重的不良影响。因此,通过干预饮食行为以减少过度进食并防控肥胖问题具有重要意义。与传统抑制控制训练对饮食行为的微弱影响不同,食物抑制控制训练具有显著效果,但其内在作用机制尚不明确。因此,本研究拟开展4个研究,共计8个实验来解决上述问题。具体来说,研究1和2,从食物抑制控制训练更新食物价值这一路径出发,考察训练能否通过提升Go食物价值,降低No-go食物价值,进而改变个体的饮食行为。研究3和4,则从食物抑制控制训练建立食物与自动反应/抑制联结这一路径出发,考察训练能否通过建立Go食物与自动反应联结,No-go食物与自动抑制联结,进而改变个体的饮食行为。本研究有助于阐明食物抑制控制训练的内在作用机制,为我国过度进食和肥胖的干预和治疗提供新思路。The issue of obesity poses significant adverse effects on the physical and mental health of the Chinese population.Intervening in eating behaviors is crucial for reducing overeating and addressing obesity.Unlike traditional inhibitory control training,which has limited effects on eating behaviors,food-specific inhibitory control training demonstrates remarkable efficacy.However,its underlying mechanisms remain unclear.This study aims to address this gap by conducting four studies comprising eight experiments.Specifically,Studies 1 and 2 explore whether food-specific inhibitory control training can alter eating behaviors by updating food values,enhancing the value of“Go”foods while reducing the value of“No-Go”foods.Studies 3 and 4 investigate whether the training can change eating behaviors by forming automatic response/inhibition associations,linking“Go”foods to automatic responses and“No-Go”foods to automatic inhibition.This study seeks to elucidate the mechanisms underlying food-specific inhibitory control training and offers new perspectives for the intervention and treatment of overeating and obesity in China.
