Aesthetic preference occurs in everyday experience. Studies have suggested that aesthetic preference (such as observing other's motion) affects social interaction via enhanced neural processing. This study investigated the effect of aesthetic preference on neural activities, in response to walking motion. Twenty participants observed biological motion (BM) representing three walking types (model-posture, good-posture, and bad-posture) and their scrambled motion (SM) during the event-related potentials measurement. The N200 and N300 amplitudes, reflecting the early sensory and the later integrational processes, were analyzed. The results revealed that the N200 amplitude of BM was greater than that of SM in the good- and bad-posture conditions. The N300 amplitude was larger in BM than SM regardless of the walking type. Exploratory regression analyses indicated that the N300 for BM, but not for SM or N200, was more negatively deflected with the increase of aesthetic preference scores. Our findings suggest that aesthetic preference enhances the later integrational process of BM represented in the N300 amplitude, whereas the early perceptual process (reflected by the N200 amplitude) is potentially modulated by familiarity rather than aesthetic preference in other's motion.
审美偏好存在于日常经验中。研究表明，审美偏好（如观察他人的动作）通过增强神经处理来影响社交互动。本研究通过事件相关电位测量，调查了审美偏好对行走运动神经活动的影响。20 名参与者观察了三种行走类型（模特姿势、良好姿势和不良姿势）的生物运动（BM）及其打乱运动（SM）。分析了反映早期感觉和后期综合过程的 N200 和 N300 振幅。结果表明，在良好姿势和不良姿势条件下，BM 的 N200 振幅大于 SM 的 N200 振幅。无论行走类型如何，BM 的 N300 振幅均大于 SM 的 N300 振幅。探索性回归分析表明，与 SM 或 N200 不同，BM 的 N300 随着审美偏好评分的增加而更负向偏转。我们的研究结果表明，审美偏好增强了 N300 中代表的 BM 的后期综合过程，而其他运动中（由 N200 振幅反映）的早期感知过程可能是由熟悉度而不是审美偏好调节的。
