Abstract：
Affective stimuli in our environment indicate reward or threat and thereby relate to approach and avoidance behavior. Previous findings suggest that affective stimuli may bias visual perception, but it remains unclear whether similar biases exist in the auditory domain. Therefore, we asked whether affective auditory voices (angry vs. neutral) influence sound distance perception. Two VR experiments (data collection 2021-2022) were conducted in which auditory stimuli were presented via loudspeakers located at positions unknown to the participants. In the first experiment (N = 44), participants actively placed a visually presented virtual agent or virtual loudspeaker in an empty room at the perceived sound source location. In the second experiment (N = 32), participants were standing in front of several virtual agents or virtual loudspeakers and had to indicate the sound source by directing their gaze toward the perceived sound location. Results in both preregistered experiments consistently showed that participants estimated the location of angry voice stimuli at greater distances than the location of neutral voice stimuli. We discuss that neither emotional nor motivational biases can account for these results. Instead, distance estimates seem to rely on listeners\' representations regarding the relationship between vocal affect and acoustic characteristics.

摘要：
我们环境中的情感刺激表示奖励或威胁，从而与接近和回避行为有关。先前的研究结果表明，情感刺激可能会偏向视觉感知，但目前尚不清楚在听觉领域是否存在类似的偏差.因此,我们问情感听觉声音是否(愤怒与中性)影响声音距离感知。进行了两个VR实验（数据收集2021-2022），其中通过位于参与者未知位置的扬声器呈现听觉刺激。在第一个实验中（N=44），参与者积极地将视觉呈现的虚拟代理或虚拟扬声器放置在感知声源位置的空房间中。在第二个实验中（N=32），参与者站在几个虚拟代理或虚拟扬声器前，必须通过将视线指向感知的声音位置来指示声源。两个预先注册的实验的结果一致表明，参与者估计愤怒的声音刺激的位置比中性声音刺激的位置更大。我们讨论了情感或动机偏见都不能解释这些结果。相反，距离估计似乎依赖于听众对声音影响和声学特征之间关系的表示。（PsycInfo数据库记录（c）2024APA，保留所有权利)。
