Despite the multisensory nature of perception, previous research on emotions has been focused on unimodal emotional cues with visual stimuli. To the best of our knowledge, there is no evidence on the extent to which incongruent emotional cues from visual and auditory sensory channels affect pupil size.
To investigate the effects of audiovisual emotional information perception on the physiological and affective response, but also to determine the impact of mismatched cues in emotional perception on these physiological indexes.
Pupil size, electrodermal activity and affective subjective responses were recorded while 30 participants were exposed to visual and auditory stimuli with varied emotional content in three different experimental conditions: pictures and sounds presented alone (unimodal), emotionally matched audio-visual stimuli (bimodal congruent) and emotionally mismatched audio-visual stimuli (bimodal incongruent).
The data revealed no effect of emotional incongruence on physiological and affective responses. On the other hand, pupil size covaried with skin conductance response (SCR), but the subjective experience was partially dissociated from autonomic responses.
Emotional stimuli are able to trigger physiological responses regardless of valence, sensory modality or level of emotional congruence.
尽管感知具有多感官性质，但之前关于情绪的研究一直集中在具有视觉刺激的单一模式情绪线索上。据我们所知，关于视觉和听觉感官通道的不一致情绪线索在何种程度上影响瞳孔大小，尚无证据。
研究视听情绪信息感知对生理和情感反应的影响，但也要确定情绪感知中不匹配线索对这些生理指标的影响。
当 30 名参与者在三种不同的实验条件下暴露于具有不同情绪内容的视觉和听觉刺激时，记录瞳孔大小、皮肤电活动和情感主观反应：单独呈现的图片和声音（单一模式）、情绪匹配的视听刺激（双模式一致）和情绪不匹配的视听刺激（双模式不一致）。
数据显示情绪不一致对生理和情感反应没有影响。另一方面，瞳孔大小与皮肤电反应（SCR）相关，但主观体验与自主反应部分分离。
无论情绪的效价、感官模态或情绪一致性水平如何，情绪刺激都能够引发生理反应。
