情绪在同种个体之间传递信号,同时也向其他物种传递信号,以促进对外部和内部线索做出具有生态行为学意义的反应。然而,一个尚未解决的问题是,情绪识别的普遍性是否延伸至超出某一物种自然听觉范围的声音信号。在此,我们探究了人类是否能感知频率偏移后的大鼠超声发声中的情绪内容。我们发现,人类受试者能够正确地将情绪效价归属于经过人工移频的发声,且这种能力在一定程度上依赖于频率偏移的程度。这表明声音情绪交流在物种间具有高度保守性,而持续的感觉暴露不太可能是这些声音表达在进化上得以保留的必要条件。
Emotions are signalled among conspecifics but also to other species to facilitate ethologically meaningful responses towards external and internal cues. An unresolved question, however, is whether the universality of emotional recognition extends to vocalizations that lie outside a species' natural auditory range. Here we asked whether humans perceive emotional content of frequency-shifted rat ultrasonic vocalizations. We found that human subjects correctly assigned emotional valence to the artificially transposed vocalizations, with certain dependencies on the degree of the frequency shift. This suggest that vocal emotional communication is highly conserved across species and that continuous sensory exposure is unlikely to be required for evolutionary preservation of these vocal expressions.
