How do we perceive voices coming from different spatial locations, and how is this affected by emotion? The current study probed the interplay between space and emotion during voice perception. Thirty participants listened to nonverbal vocalizations coming from different locations around the head (left right; front back), and differing in valence (neutral, positive [amusement] or negative [anger]). They were instructed to identify the location of the vocalizations (Experiment 1) and to evaluate their emotional qualities (Experiment 2). Emotion-space interactions were observed, but only in Experiment 1: emotional vocalizations were better localised than neutral ones when they were presented from the back and the right side. In Experiment 2, emotion recognition accuracy was increased for positive negative and neutral vocalizations, and perceived arousal was increased for emotional neutral vocalizations, but this was independent of spatial location. These findings indicate that emotional salience affects how we perceive the spatial location of voices. They additionally suggest that the interaction between spatial ("where") and emotional ("what") properties of the voice differs as a function of task.
我们如何感知来自不同空间位置的声音，情绪对此有何影响？本研究探讨了声音感知过程中空间和情绪的相互作用。30 名参与者听取了来自头部不同位置（左、右、前、后）的非言语发声，这些发声在效价上有所不同（中性、积极[愉悦]或消极[愤怒]）。他们被指示识别发声的位置（实验 1）并评估其情绪质量（实验 2）。观察到了情绪-空间的相互作用，但仅在实验 1 中：当发声来自背面和右侧时，情绪发声比中性发声的定位更好。在实验 2 中，对正性、负性和中性发声的识别准确性增加，对情绪发声的感知唤醒度增加，但这与空间位置无关。这些发现表明，情绪显著性影响我们感知声音空间位置的方式。此外，它们表明，声音的空间（“在哪里”）和情绪（“是什么”）属性之间的相互作用因任务而异。
