The present study asked whether the processing of affective prosody is modulated by spatial attention. Pseudo-words with a neutral, happy, threatening, and fearful prosody were presented at two spatial positions. Participants attended to one position in order to detect infrequent targets. Emotional prosody was task irrelevant. The electro-encephalogram (EEG) was recorded to assess processing differences as a function of spatial attention and emotional valence.
Event-related potentials (ERPs) differed as a function of emotional prosody both when attended and when unattended. While emotional prosody effects interacted with effects of spatial attention at early processing levels (< 200 ms), these effects were additive at later processing stages (> 200 ms).
Emotional prosody, therefore, seems to be partially processed outside the focus of spatial attention. Whereas at early sensory processing stages spatial attention modulates the degree of emotional voice processing as a function of emotional valence, emotional prosody is processed outside of the focus of spatial attention at later processing stages.
本研究旨在探讨情感韵律的加工是否受到空间注意的调节。呈现具有中性、快乐、威胁和恐惧韵律的伪词，置于两个空间位置。参与者专注于一个位置，以检测不常见的目标。情感韵律与任务无关。记录脑电图（EEG）以评估空间注意和情绪效价的功能差异。
当被注意和未被注意时，事件相关电位（ERP）都随情感韵律而变化。虽然情绪韵律的影响与早期处理阶段（<200ms）的空间注意影响相互作用，但这些影响在后期处理阶段（>200ms）是累加的。
因此，情感韵律似乎在空间注意的焦点之外部分加工。虽然在早期的感觉处理阶段，空间注意根据情绪效价调节情感语音处理的程度，但在后期的处理阶段，情感韵律在空间注意的焦点之外被处理。
