We present an investigation of the perception of authenticity in audiovisual laughter, in which we contrast spontaneous and volitional samples and examine the contributions of unimodal affective information to multimodal percepts. In a pilot study, we demonstrate that listeners perceive spontaneous laughs as more authentic than volitional ones, both in unimodal (audio-only, visual-only) and multimodal contexts (audiovisual). In the main experiment, we show that the discriminability of volitional and spontaneous laughter is enhanced for multimodal laughter. Analyses of relationships between affective ratings and the perception of authenticity show that, while both unimodal percepts significantly predict evaluations of audiovisual laughter, it is auditory affective cues that have the greater influence on multimodal percepts. We discuss differences and potential mismatches in emotion signalling through voices and faces, in the context of spontaneous and volitional behaviour, and highlight issues that should be addressed in future studies of dynamic multimodal emotion processing.
我们展示了一项关于视听笑声中真实性感知的调查，其中我们对比了自发和有意的样本，并研究单峰情感信息对多峰感知的贡献。在一项初步研究中，我们证明，在单峰（仅音频、仅视觉）和多峰（视听）情境下，听众都认为自发笑声比有意笑声更真实。在主要实验中，我们表明多峰笑声增强了有意和自发笑声的可辨别性。情感评分与真实性感知之间关系的分析表明，虽然两种单峰感知都能显著预测视听笑声的评价，但对多峰感知影响更大的是听觉情感线索。我们讨论了在自发和有意行为背景下，通过声音和面部进行情感信号传递的差异和潜在不匹配，并强调了动态多峰情感处理未来研究中应解决的问题。
