【摘要】：眼睛能够传递丰富的信息,快速准确地接收、解读他人的眼神信息是一项在进化过程中逐步形成的重要的社会认知能力。有研究显示,当观察者发现他人正在注视某一方向或物体时,总是会自动地追随其视线,该现象称为注视追随,而他人的视线则成为注视线索。注视追随行为对表情识别、语言习得以及人际沟通能力的发展均起着重要的作用。然而以往针对注视追随行为的研究多集中于单个注视线索场景,在现实生活中,人们经常需要面对包含不同方向注视线索的多人交互场景。视觉系统如何解决注视线索的冲突竞争,是顺利完成多人交互的关键问题之一。因此单一注视线索的研究由于简化了现实场景中的信息复杂性,其结论尚不能为多人同时存在的复杂场景提供完整的解释和预测,需要对上述问题进行系统探讨。本研究对经典注视线索范式进行改良,采用多个注视线索替代以往研究范式中单一的注视线索,构建多人注视线索冲突的场景。以线索效应为指标,通过操纵人脸表情或数量差异等因素,改变线索的提示作用强度,系统探讨了注视线索冲突场景中的注视追随行为及其机制。整个研究包含三部分。研究一以恐惧表情变化人脸为例,主要探讨在两人注视线索冲突场景下,视觉系统是否能基于线索提示作用的强度,进行注视追随选择。研究二对该选择性追随的发生阶段进行探讨。研究三将两人场景推广至群体场景,考察冲突注视线索的数量差异对选择性追随行为的影响。获得以下主要结果:(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得到选择性追随。(2)相对于高兴表情,与个体生存关系更为密切的恐惧表情能够增强注视线索的提示作用。(3)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。(4)冲突注视线索的选择发生在晚期反应选择阶段。上述研究结果表明:在多人注视线索发生冲突竞争的场景中,视觉系统可以基于恐惧表情和数量差异,调节线索提示作用强度,从而执行选择性注视追随。
[Abstract]:It is an important social cognitive ability that the eyes can transmit abundant information, receive and interpret the eye information of others quickly and accurately. Studies have shown that when observers find that others are looking in a certain direction or object, they always follow their eyes automatically. This phenomenon is called gaze following, and the sight of others becomes a fixation clue. Gaze following plays an important role in facial expression recognition, language acquisition and interpersonal communication. However, in the past, most of the studies focused on a single fixation clue scene, and in real life, people often have to face the multi-person interaction scene with different direction fixation cues. How to solve the conflict and competition of fixation cues in visual system is one of the key problems to complete multiplayer interaction successfully. Therefore, the study of single gaze cues can not provide a complete explanation and prediction for the complex scenes in which many people exist at the same time, because it simplifies the complexity of information in the real scene, so the above problems need to be discussed systematically. In this study, the classic fixation cues paradigm is improved, and multiple fixation cues are used to replace the single fixation cues in the previous research paradigm, and the scene of multiple fixation cues conflict is constructed. Based on the cue-effect, by manipulating the facial expression or the number difference, and changing the cues' hint intensity, this paper systematically discusses the fixation following behavior and its mechanism in the fixation cue-conflict scene. The whole study consists of three parts. In the first study, taking the face of fear expression change as an example, this paper mainly discusses whether the visual system can choose the gaze following based on the intensity of cue-prompting in the conflict scene of two fixation cues. In the second study, the stage of the selective follow was discussed. In the third study, the effects of the number of conflicting fixation cues on the selective follow behavior were investigated by popularizing the two-person scene to the group scene. The main results are as follows: 1) facial expression information affects the selection of multiple fixation cues in conflict scenarios, and gazing cues that integrate fear expressions are selectively followed. 2) relative to happy expressions, The fear expression, which is more closely related to individual survival, can enhance the cues' cues.) in the multi-person scene where the gazing cues conflict, people tend to follow the direction of most people's gaze. That is to say, the clue cues of majority school are more effective. 4) the choice of conflict fixation cues occurs in the stage of late reaction selection. The results show that the visual system can adjust the intensity of cues based on fear expression and quantity difference in the scene of conflict and competition of multiple fixation cues and then perform selective fixation follow.
