Abstract：
Gaze direction and pupil dilation play a critical role in communication and social interaction due to their ability to redirect and capture our attention and their relevance for emotional information. The present study aimed to explore whether the pupil size and gaze direction of the speaker affect language comprehension. Participants listened to sentences that could be correct or contain a syntactic anomaly, while the static face of a speaker was manipulated in terms of gaze direction (direct, averted) and pupil size (mydriasis, miosis). Left anterior negativity (LAN) and P600 linguistic event-related potential components were observed in response to syntactic anomalies across all conditions. The speaker\'s gaze did not impact syntactic comprehension. However, the amplitude of the LAN component for mydriasis (dilated pupil) was larger than for miosis (constricted pupil) condition. Larger pupils are generally associated with care, trust, interest, and attention, which might facilitate syntactic processing at early automatic stages. The result also supports the permeable and context-dependent nature of syntax. Previous studies also support an automatic nature of syntax (fast and efficient), which combined with the permeability to relevant sources of communicative information, such as pupil size and emotions, is highly adaptive for language comprehension and social interaction.
摘要：
凝视方向和瞳孔扩张在沟通和社交互动中起着至关重要的作用，因为它们能够重定向和捕获我们的注意力和情感信息的相关性。本研究旨在探讨说话者的瞳孔大小和注视方向是否会影响语言理解。参与者听了可能正确或包含句法异常的句子，而说话者的静态面部是根据注视方向(直接，避免)和瞳孔大小(散瞳，瞳孔缩小）。在所有情况下，都观察到左前负（LAN）和P600语言ERP成分的句法异常。说话者的目光并不影响句法理解。然而,散瞳（瞳孔扩大）的LAN分量的幅度大于瞳孔缩小（瞳孔缩小）的幅度。较大的学生通常与护理有关，信任,兴趣,和注意,这可能有助于在早期自动阶段进行句法处理。结果还支持语法的渗透性和上下文相关性质。以前的研究也支持语法的自动性质(快速和高效)，再加上对相关传播信息来源的渗透性，比如瞳孔大小和情绪，对语言理解和社交互动具有高度适应性。
