颜面部审美认知中的眼动变化

眼动与人的心理活动有关.眼动系指包括注视、眼跳和追随3种运动形式,三者经常交错在一起,目的均为将要注意的刺激物成像于中央窝区域,以形成清晰的图像.眼动仪可精确记录以上指标,以便研究者分析被试者的认知与心理活动.人们在看见面孔时,潜意识中会进行审美评判,自上而下的意识会影响被试者注意力的分布.面孔因素、被试者因素和任务因素可引起基本的眼动模式的变化,即在三角形分布的视觉注意基础上各面部特征所占的视觉注意比例的变化.错畸形、唇腭裂和面部畸形等异常颜面部会改变眼动模式,而眼动仪既为异常颜面的量化提供了新技术,也为纠正异常颜面提供了新的评判方法.眼动追踪技术客观地记录了人们在颜面部审美过程中的生理变化,揭示了颜面部审美的客观规律.将其收集的数据通过计算机分层,可为疾病的分级和治疗需要提供参考.

Eye tracking study of facial aesthetics

Eye movement is related to psychology. This movement includes fixation, saccade, and pursuit movement, which serve as stimuli in the foveal area of the eyes. Eye trackers precisely record eye movement to analyze the cognitive and psychological activities of subjects. People viewing faces undergo aesthetic judgment subconsciously, and the conscious can influence the attention allocation of subjects. Faces, subjects, and task factors can change the basic eye movement pattern. The visual attention allocation of faces changes on the basis of the triangular eye movement pattern. Malocclusion, cleft lip and palate, and facial deformity can change the eye movement pattern. Eye trackers can quantify the attention deviation in abnormal faces and provide a new evaluation method to determine the effect of correcting the abnormality. Such devices objectively record the physiological changes in people during the aesthetic processing of faces, thereby facilitating the identification of the facial aesthetic pattern. In the future, eye trackers can be used to assess treatment needs, level diseases, and evaluate the curative effect of deformed faces on the basis of eye tracking data and computer science.
