Emotional faces are commonly used as stimuli in a wide number of research fields. The present study provides values of 198 pictures from one of the amplest available face databases, the Karolinska Directed Emotional Faces (KDEF). We used a new validation strategy that consisted of presenting pairs of faces which included an emotional face (i.e., angry, happy, sad) and its corresponding neutral face from the same model. This design allowed participants to keep a comparison face (i.e., neutral) as a constant anchor point to evaluate parameters on each emotional expression presented. Raters were asked to judge both the prototypicality of the emotional expressions (i.e., the degree to which they represent their corresponding emotional prototypes) as well as their emotional intensity. We finally discuss the potential advantages of this anchor-point method as a system to elicit judgments on facial emotional expressions.
情绪面孔通常被用作广泛研究领域的刺激物。本研究提供了来自可用的最大面部数据库之一的 198 张图片的数值，即卡罗林斯卡定向情绪面孔（KDEF）。我们使用了一种新的验证策略，包括呈现一对包括情绪面孔（即愤怒、快乐、悲伤）及其来自同一模型的相应中性面孔的面孔。这种设计允许参与者保留一个比较面孔（即中性）作为恒定的锚点，以评估呈现的每个情绪表达的参数。评估者被要求判断情绪表达的典型性（即它们在多大程度上代表其相应的情绪原型）以及情绪强度。我们最后讨论了这种锚点方法作为一种引出对面部情绪表达的判断的系统的潜在优势。
