摘要
最原始的生物运动之一是行走。人类的视觉不断处理行走动作,以预测社会互动,避免潜在的碰撞。与直觉相反,当处理多个行走生物运动时,视觉系统通过单个运动中的参考排斥(偏离类别边界方向)和长时间的排斥适应(偏离先前刺激方向)来优化感知。然而,我们如何在短期运动中独特地感知步行的生物运动尚不清楚。在这里,通过要求参与者调整方向直到与他们刚刚看到的方向一致,我们发现了行走生物运动感知中的序列依赖(对先前刺激方向的偏向)(实验1)。我们在非生物运动(旋转球体)中发现了类似的效果,但幅度更大(实验2)。此外,生物运动的序列依赖性与参考斥力共存,而非生物运动与参考吸引力共存。另一个实验证明了生物和非生物运动之间的不对称相互影响:吸引序列依赖可以在它们之间转移,并且从生物运动到非生物运动更大(实验3)。这种不对称性明显大于反向生物运动和非生物运动之间的不对称性,这表明这种效应在很大程度上是由生物运动独特的社会意义驱动的(实验4)。结果表明,视觉在处理生物运动时实现了序列依赖,以保持相对稳定的时间表征,但与非生物运动相比,视觉以较少的偏差方式避免了太大的偏差。(PsycInfo Database Record (c) 2025 APA,版权所有)。
Serial dependence in biological motion perception: Unique patterns compared to nonbiological motion.
One of the most primitive biological motions is walking. Human vision constantly processes walking movements to anticipate social interactions and avert potential collisions. Counterintuitively, when processing multiple walking biological motions, the visual system optimizes the perception through reference repulsion within a single motion (a bias away from the category boundary direction) and repulsive adaptation in a prolonged time (a bias away from the direction of preceding stimuli). However, how we uniquely perceive walking biological motion across short-term movements remains unclear. Here, by asking participants to adjust the direction until it matches the one they just saw, we uncovered the serial dependence (a bias toward the direction of preceding stimuli) in walking biological motion perception (Experiment 1). We found a similar effect for nonbiological motion (a rotating sphere) but with a greater amplitude (Experiment 2). Furthermore, serial dependence in biological motion coexisted with reference repulsion, while nonbiological motion coexisted with reference attraction. An additional experiment demonstrated an asymmetric mutual influence between biological and nonbiological motion: the attractive serial dependence could transfer between them and was greater from biological to nonbiological motion (Experiment 3). This asymmetry was significantly greater than that observed between inverted biological motion and nonbiological motion, suggesting that the effect is largely driven by the unique social significance of biological motion (Experiment 4). The results suggest that vision implements serial dependence when processing biological motion to maintain a relatively steady representation across time but in a less biased way than nonbiological motion to avoid too much deviation.
