隐性种族偏见已被证明会影响决策和行为。它还可能通过增加社会群体之间的感知差异来改变感知体验。我们通过测试代表黑人和白人面孔的分布式血氧水平依赖(BOLD)模式在具有较高内隐种族偏见的参与者中是否更不相似，来研究这一现象如何在神经水平上表达。我们使用多体素模式分析来预测参与者正在观看的人脸的种族。我们成功地根据早期枕叶视觉皮质、枕叶面部区域和梭形面部区域(FFA)的大胆激活模式预测了人脸的种族。虽然早期视觉区域的大胆激活模式可能反映了不同的知觉特征，使得所有参与者都能成功预测，但基于FFA(高级面孔加工区域)的大胆激活模式的成功预测仅限于高度亲白偏见的参与者。这些发现表明，更强的内隐亲白偏见降低了黑人和白人面孔神经表征的相似性。
Implicit race bias has been shown to affect decisions and behaviors. It may also change perceptual experience by increasing perceived differences between social groups. We investigated how this phenomenon may be expressed at the neural level by testing whether the distributed blood-oxygenation-level-dependent (BOLD) patterns representing Black and White faces are more dissimilar in participants with higher implicit race bias. We used multivoxel pattern analysis to predict the race of faces participants were viewing. We successfully predicted the race of the faces on the basis of BOLD activation patterns in early occipital visual cortex, occipital face area, and fusiform face area (FFA). Whereas BOLD activation patterns in early visual regions, likely reflecting different perceptual features, allowed successful prediction for all participants, successful prediction on the basis of BOLD activation patterns in FFA, a high-level face-processing region, was restricted to participants with high pro-White bias. These findings suggest that stronger implicit pro-White bias decreases the similarity of neural representations of Black and White faces.
