饮食失调在大学生中很普遍，但大学生在识别饮食失调（ED）的存在方面并不准确，尤其是在涉及种族的情况下。关于小插图形式的诊断能力的研究很多，但除此之外的研究很少。例如，目前尚不清楚面部特征，如女性气质，如何影响观察者对饮食失调可能性的看法，这取决于种族。在目前的研究中，我们研究了关于面部外观和饮食失调的偏见如何根据面部图像的种族而有所不同。使用一种被称为反向相关的技术，我们用白脸和黑脸来估计与饮食失调的感知可能性相关的图像模板。具体来说，我们招募了28名大学生，根据图像噪声存在时饮食失调诊断的感知可能性，对白人和黑人面孔进行分类。随后，我们要求亚马逊土耳其机器人的参与者根据感知到的ED可能性和女性特征，对结果中特定种族的面部模板进行分类。与高可能性ED诊断相对应的模板通过第二个独立参与者样本在高于机会水平上与低可能性图像区分开来。对于黑人面孔来说，在高于概率水平上，与ED诊断的高可能性相对应的模板也被选择为比低可能性模板更女性化，而对于白人面孔则没有这种影响。这些结果表明，对女性气质和饮食失调可能性的刻板印象可能与感知过程相互作用。
Eating disorders are prevalent in college students but college students are not accurate in identifying the presence of eating disorders (ED) especially when race is involved. Much has been researched about diagnostic ability in vignette form, but little outside of this. For example, it is not known how facial features, such as perceived femininity, may affect observers’ beliefs about the likelihood of disordered eating depending on race. In the present study, we examined how biases regarding facial appearance and disordered eating may differ depending on the race of face images. Using a technique called reverse correlation, we estimated the image templates associated with perceived likelihood of disordered eating using both White and Black Faces. Specifically, we recruited 28 college students who categorized White and Black faces according to perceived likelihood of an eating disorder diagnosis in the presence of image noise. Subsequently, we asked Amazon Mechanical Turk participants to categorize the resulting race-specific face templates according to perceived ED likelihood and femininity. The templates corresponding to a high likelihood of an ED diagnosis were distinguished from low-likelihood images by this second independent participant sample at above-chance levels. For Black faces, the templates corresponding to a high likelihood of an ED diagnosis were also selected as more feminine than low-likelihood templates at an above-chance level, whereas there was no such effect found for White faces. These results suggest that stereotyped beliefs about both femininity and the likelihood of disordered eating may interact with perceptual processes.
