We investigated how emotionality of visual background context influenced perceptual ratings of faces. In two experiments participants rated how positive or negative a face, with a neutral expression (Experiment 1), or unambiguous emotional expression (happy/angry; Experiment 2), appeared when viewed overlaid onto positive, negative, or neutral background context scenes. Faces viewed in a positive context were rated as appearing more positive than when in a neutral or negative context, and faces in negative contexts were rated more negative than when in a positive or neutral context, regardless of the emotional expression portrayed. Notably, congruency of valence in face expression and background context significantly influenced face ratings. These findings suggest that human judgements of faces are relative, and significantly influenced by contextual factors.
我们研究了视觉背景情境的情感性如何影响对面部的感知评分。在两项实验中，参与者对一张带有中性表情（实验1）或明确情感表情（开心/愤怒；实验2）的面部，在叠加于积极、消极或中性背景情境场景上时所呈现出的积极或消极程度进行评分。无论所描绘的情感表情如何，在积极情境中看到的面部被评为比在中性或消极情境中看起来更积极，而在消极情境中的面部被评为比在积极或中性情境中更消极。值得注意的是，面部表情和背景情境中效价的一致性显著影响面部评分。这些发现表明，人类对面部的判断是相对的，并且受到情境因素的显著影响。
