We examined the role of single features and feature configurations in the effect of schematic faces on rated threat. A total of 101 medical students rated their emotional impression of schematic facial stimuli using semantic differential scales (Activity, Negative Valence, and Potency). In different parts of the experiment, the ratings concerned single features, eyebrow-mouth configurations, or complete faces. Although eyebrows emerged as the overall most important feature, the effect of features was modulated by configuration. Simple configurations of eyebrows and mouth appeared to convey threat and nonthreat in a way highly similar to that of complete faces. In most cases, the configurations of eyebrows and mouth could significantly predict the effect of the complete faces.
我们研究了单一特征和特征组合在示意性面孔对威胁评级影响中的作用。共有101名医科学生使用语义差异量表（活跃度、负性效价和效用力）对示意性面部刺激的情感印象进行评级。在实验的不同部分，评级涉及单一特征、眉毛-嘴巴组合或完整面孔。尽管眉毛总体上是最重要的特征，但特征的影响会受到组合的调节。眉毛和嘴巴的简单组合似乎以与完整面孔非常相似的方式传达威胁和非威胁信息。在大多数情况下，眉毛和嘴巴的组合能够显著预测完整面孔的效果。
