Objective. Concurrent changes in physiological signals across multiple listeners (physiological synchrony—PS), as caused by shared affective or cognitive processes, may be a suitable marker of selective attentional focus. We aimed to identify the selective attention of participants based on PS with individuals sharing attention with respect to different stimulus aspects. Approach. We determined PS in electroencephalography (EEG), electrodermal activity (EDA) and electrocardiographic inter-beat interval (IBI) of participants who all heard the exact same audio track, but were instructed to either attend to the audiobook or to interspersed auditory events such as affective sounds and beeps that attending participants needed to keep track of. Main results. PS in all three measures reflected the selective attentional focus of participants. In EEG and EDA, PS was higher for participants when linked to participants with the same attentional instructions than when ...

脑电图，皮肤电活动和心率的生理同步反映了共同的选择性听觉注意。

目的。由共享的情感或认知过程引起的跨多个听众的生理信号同时变化（生理同步-PS）可能是选择性注意焦点的合适标志。我们旨在识别基于PS的参与者的选择性关注，其中个体在不同刺激方面共享关注。方法。我们在听觉完全相同的音轨，但被指示参加有声读物或穿插听觉事件（例如，参加者需要跟踪的情感声音和蜂鸣声。主要结果。所有这三个指标中的PS反映了参与者的选择性注意重点。
