We explore dance video clip stimuli as a means to test human observers' accuracy in detecting genuine emotional expressivity in full-body movements. Stimuli of every-day-type full-body expressions of emotions usually use culturally very recognizable actions (e.g. fist shaking for anger, etc). However, expressive dance movement stimuli can be created to contain fully abstract movements. The expressivity results from subtle variations in the body movements of the expressor, and emotions cannot be recognised by observers via particular actions (e.g. fist shaking, etc).

Forty-one participants watched and rated 24 pairs of short dance videos –from a published normalised dance stimuli library– in randomised order (N = 48). Of each carefully matched pair, one version of the full-body movement sequence had been danced to be emotionally genuinely expressive (clip a), while the other version of the same sequence (clip b) had been danced –while technically correct– without any emotional expressivity. Participants rated (i) expressivity (to test their accuracy; block 1), and (ii) how much they liked each movement (an implicit measure to test their emotional response (“liking”); block 2).

Participants rated clips that were intended to be expressive as more expressive (part 1: expressivity ratings), and liked those expressive clips more than the non-expressive clips (part 2: liking ratings). Besides, their galvanic skin response differed, depending on the category of clips they were watching (expressive vs. non-expressive), and this relationship was modulated by interceptive accuracy and arts experience. Results are discussed in relation to the Body Precision Hypothesis and the Hypothesis of Constructed Emotion.

我们探索舞蹈视频剪辑刺激，以测试人类观察者检测全身运动中真实情感表达的准确性。日常情绪表达的刺激通常使用在文化上非常容易识别的动作（例如，为愤怒而拳头摇动等）。但是，可以创建富有表现力的舞蹈动作刺激以包含完全抽象的动作。表现力是由于表达者身体动作的细微变化而产生的，观察者无法通过特定的动作（例如，拳头摇晃等）来识别情绪。

41名参与者以随机顺序观看和评价了24对短舞蹈视频（来自已发布的标准化舞蹈刺激库），并对其进行了评级（N  = 48）。在每对经过仔细匹配的对中，已将全身运动序列的一个版本跳舞为具有情感上的真实表现力（片段A），而在相同的序列的另一版本（片段b）则进行了跳舞（虽然技术上正确），却没有任何动作。情感表达。参与者对（i）表现力（以测试其准确性；框1）和（ii）他们对每个动作的喜欢程度进行了评估（一种隐含的量度，以测试其情绪反应（“喜欢”）；框2）。

参与者将旨在表现力的片段评分为更具表现力的片段（第1部分：表达能力等级），并且比那些非表达性片段更喜欢这些表达片段（第2部分：喜欢的评分）。此外，根据他们正在观看的剪辑的类别（表现性与非表现性），他们对皮肤的原电池反应也有所不同，并且这种关系受到截取性准确性和艺术经验的调节。讨论了有关身体精确度假说和建构情绪假说的结果。
