多人冲突注视线索的选择性追随及其认知机制

As an important cognitive ability in interpersonal communication, gaze following refers to the phenomenon of people would automatically redirect their visual attention by following others' gaze direction. Comparing to single gaze scenes in previous studies, most of the scenes in real life are interactive ones including many eye gazes directing to various directions. Hence it's far from clear that how visual system process the confliction between gazes with different orientations. Based on applicants' previous findings, current project aims to systematically explore the selected gaze following phenomenon and its underlying mechanism by adopting behavioral paradigms including dot-probe and working memory tasks, as well as event-related potential method. Three studies are planned as follows: Study 1 investigates how the quantity difference of conflicting gaze cues affects selective gaze following; Study 2 concerns the influence of social information (facial expression) on selective gaze following; and Study 3 further clarify the cognitive mechanism and neural basis of selective gaze following behavior. Part of the project plan has been testified in preliminary experiments. Current project would help providing psychological evidence for appearance and spreading of herd behaviors, deepening the knowledge on social nature of gaze cue, and finally building cognitive model for selective gaze following phenomenon. In addition, the applicant had published three research articles as the first author in international authoritative publications, and is fully capable of conducting cognitive experiments. All those lay a solid foundation for carrying out current project smoothly.

注视追随是指个体通过自动追随他人的注视方向实现注意定向的行为现象，是人际交往中的一项重要能力。现实生活中个体常要面对包含注视线索方向冲突的多人交互场景，但以往针对注视追随现象的研究多集中于单个注视线索场景，其研究结论的解释效力有限。本项目基于申请人的前期研究，采用点探测和工作记忆任务，并结合事件相关电位技术，对冲突注视线索下的选择性追随行为及其机制进行系统探讨。研究一考察冲突线索数量差异对选择性注视追随的影响；研究二考察社会信息(人脸表情)对选择性注视追随的调节作用；研究三考察选择性注视追随的内在选择机制及其神经基础。该项目的部分研究方案已得到预实验结果的支持。本项目的实施有助于深化对注视线索社会本质的认识，建立选择性注视追随的认知模型，亦可为揭示群体行为的发生和传播规律提供心理学依据。申请人经过系统的认知科学训练，已在国际权威刊物上发表一作论文3篇，为本项目的顺利实施提供了坚实基础。

注视追随是指个体通过自动追随他人的注视方向实现注意定向的行为现象，是人际交往中的一项重要能力。现实生活中个体常要面对包含注视线索方向冲突的多人交互场景，但以往针对注视追随现象的研究多集中于单个注视线索场景，其研究结论的解释效力有限。本项目采用点探测和工作记忆任务，并结合事件相关电位技术，对冲突注视线索下的选择性追随行为及其机制进行系统探讨。研究结果发现：（1）表情信息影响冲突场景下多个注视线索的选择，整合恐惧表情的注视线索相对于中性表情线索得到选择性追随，其注视方向信息的知觉加工和工作记忆均得到了显著提升；（2）在注视线索发生冲突的多人场景中，人们倾向于追随多数人的注视方向，即多数派的线索提示作用更强，其注视方向知觉加工和工作记忆绩效均得到了显著提升；（3）冲突注视线索的选择追随没有增强注视线索本身的知觉表征，因而更可能是发生在晚期的信息利用反应阶段。.本研究创造出一系列探测多人注视线索选择性追随现象及其加工机制的新范式，为后续在多人交互场景下的注视线索研究提供了有效工具。研究结果对拓展多人注视线索加工理论，深化对注视线索本质的认识具有重要意义。为揭示群体中的信息扩散、行为传染等现象背后的规律提供了心理学依据。.项目执行期间发表相关SSCI/SCI论文3篇，CSSCI中文1篇，培养硕士研究生5名，实现了项目预期目标。
