这篇文章介绍了免费提供的波鸿情绪刺激集(BESST)，它包含身体和面部的图片，描绘了一种中性的表情或六种基本情绪(快乐、悲伤、恐惧、愤怒、厌恶和惊讶)中的一种，从两个不同的角度(0度正视VS相机向左避开45度)呈现。该集合包括565张正面和564张遮盖面部表情的真实身体照片，以及560张正面和560张避免视角的人脸，这些人脸是使用FaceGen 3.5 Moeller合成的。所有的刺激都根据分类的准确性和表情的自然性进行了验证。此外，每个面部刺激被变形为三个年龄版本(20/40/60岁)。结果显示，即使在快速强迫选择的条件下，也能很好地识别预期的面部表情，这与常见的实验设置相对应。刺激物的平均自然度等级介于中到高之间。(C)2012爱思唯尔爱尔兰有限公司。保留所有权利。
This article introduces the freely available Bochum Emotional Stimulus Set (BESST), which contains pictures of bodies and faces depicting either a neutral expression or one of the six basic emotions (happiness, sadness, fear, anger, disgust, and surprise), presented from two different perspectives (0 degrees frontal view vs. camera averted by 45 degrees to the left). The set comprises 565 frontal view and 564 averted view pictures of real-life bodies with masked facial expressions and 560 frontal and 560 averted view faces which were synthetically created using the FaceGen 3.5 Modeller. All stimuli were validated in terms of categorization accuracy and the perceived naturalness of the expression. Additionally, each facial stimulus was morphed into three age versions (20/40/60 years). The results show high recognition of the intended facial expressions, even under speeded forced-choice conditions, as corresponds to common experimental settings. The average naturalness ratings for the stimuli range between medium and high. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
