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° frontal view vs. camera averted by 45° 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.
本文介绍了免费的博霍姆情感刺激集（BESST），其中包含描绘中性表情或六种基本情绪（快乐、悲伤、恐惧、愤怒、厌恶和惊讶）的身体和面部图片，分别从两个不同的视角（0°正面视角与向左转 45°的相机视角）呈现。该集合包括 565 张正面视角和 564 张左偏视角的真实身体的面具表情图片，以及 560 张正面和 560 张左偏视角的使用 FaceGen 3.5 Modeller 合成的面部图片。所有刺激物在分类准确性和表情的感知自然度方面都经过了验证。此外，每个面部刺激物都被变形为三个年龄版本（20/40/60 岁）。结果表明，即使在快速强制选择条件下，也能高度识别预期的面部表情，这与常见的实验设置相符。刺激物的平均自然度评分在中等和高等之间。
