全身表情是与面部自然相关的主要视觉刺激类别之一，在过去十年中，对身体表情如何处理的神经科学研究已进入研究议程。在这里，我们描述了刺激集的全身表情被称为身体表达动作刺激测试（BEAST），我们提供了验证数据，这些材料的情感研究人员的社区使用。该数据库由来自46名演员的254个全身表情组成，表达4种情绪（愤怒，恐惧，快乐和悲伤）。在所有的照片中，演员的脸都是模糊的，参与者被要求在四个选择强迫选择任务中对刺激中表达的情绪进行分类。结果表明，所有的情绪都被很好地识别，悲伤是最容易的，其次是恐惧，而快乐是最困难的。BEAST似乎是对目前可用的评估情感信号识别的工具的有价值的补充。它可以用于外显识别任务以及匹配任务和内隐任务，结合面部表情，情感韵律，或与情感图片作为健康受试者以及临床人群的背景。
Whole body expressions are among the main visual stimulus categories that are naturally associated with faces and the neuroscientific investigation of how body expressions are processed has entered the research agenda this last decade. Here we describe the stimulus set of whole body expressions termed bodily expressive action stimulus test (BEAST), and we provide validation data for use of these materials by the community of emotion researchers. The database was composed of 254 whole body expressions from 46 actors expressing 4 emotions (anger, fear, happiness, and sadness). In all pictures the face of the actor was blurred and participants were asked to categorize the emotions expressed in the stimuli in a four alternative-forced-choice task. The results show that all emotions are well recognized, with sadness being the easiest, followed by fear, whereas happiness was the most difficult. The BEAST appears a valuable addition to currently available tools for assessing recognition of affective signals. It can be used in explicit recognition tasks as well as in matching tasks and in implicit tasks, combined either with facial expressions, with affective prosody, or presented with affective pictures as context in healthy subjects as well as in clinical populations.
