Boundary theory of eating suggests that restricting food consumption takes vast cognitive resources, so it may impact food consumption of restrained eaters while emotion occupies cognitive resources. However, the effects of emotion on inhibitory control of different subgroups of restrained eaters are still unclear. Present study is aimed to investigate the differ- ence of inhibitory control by Go-Nogo paradigm between two different subgroups of restrained eaters under both threshold emotion and subliminal affective priming. The results show that the inhibitory control in response to food-cues of unsuccessful restrained eaters is particularly inter- fered by negative emotion. On the contrary, there is no such effect on successful restrained eaters. The different influence of negative emotion on different subgroups might be one of the most im- portant factors for successful restrained eating. Keywords Restrained Eater, Emot
