恐惧和污名化经常被用来激励体重较高的人从事健康的行为，但这些策略有时适得其反，导致不良后果。在本研究中，体重耻辱感对认知（即抑制控制）和食物选择（即卡路里选择）的影响在自认为超重的个体中进行了研究。据预测，当参与者读到对体重较高的个体的歧视与对外群体的歧视时，他们在抑制控制任务中表现得更差，在食物选择任务中订购更多的卡路里。参与者完成了在线预筛选，评估他们是否认为自己超重，以及他们对体重耻辱的看法。研究人员邀请那些认为自己超重的人进入实验室，完成操纵体重歧视的任务，然后测量抑制控制和食物选择。参与者对体重的耻辱感越高，他们在抑制控制任务中的表现就越差，当他们读到对体重较高的人的歧视时，他们会点更多的卡路里。当参与者读到对外群体的歧视时，没有观察到这些关系。目前的研究结果提供了证据，表明对体重耻辱的认识对于理解基于体重的歧视的影响至关重要。此外，这些结果对于理解和解决基于体重的耻辱感的心理和生理后果具有理论和实践意义。
Fear and stigmatization are often used to motivate individuals with higher body weight to engage in healthy behaviors, but these strategies are sometimes counterproductive, leading to undesirable outcomes. In the present study, the impact of weight-based stigma on cognition (i.e., inhibitory control) and food selection (i.e., calories selected) was examined among individuals who consider themselves to be overweight. It was predicted that participants higher in perceived weight stigma would perform more poorly on an inhibitory control task and order more calories on a food selection task when they read about discrimination against individuals with higher weight versus discrimination against an out-group. Participants completed online prescreen measures assessing whether they considered themselves to be overweight and their perceptions of weight stigma. Individuals who considered themselves to be overweight were invited into the laboratory to complete tasks that manipulated weight-based discrimination, then inhibitory control and food selection were measured. The higher participants were in perceived weight stigma, the more poorly they performed on the inhibitory control task and the more calories they ordered when they read about discrimination against individuals with higher body weight. These relationships were not observed when participants read about discrimination against an out-group. The present findings provide evidence that perceptions of weight stigma are critical in understanding the impact of weight-based discrimination. Additionally, these results have theoretical and practical implications for both understanding and addressing the psychological and physical consequences of weight-based stigma.
