The present study was designed to gain a deeper understanding of the processing of biological motion stimuli. To this end, we investigated if the inhibition of return (IoR) effect emerges in initiation times and trajectories of pointing movements to targets in left and right space where the preceding cues were pointing movement of a human model or a dot with the same biological motion. Targets were randomly presented in the same or opposite side from the direction of the motion cue. It was hypothesised that the visuomotor system should resonate with the biological motion of a dot, but that the human model should exaggerate the effect. Thus, the human model should trigger stronger attention shifts compared with the dot model and lead to more robust IoR effects in both spatial (movement) and temporal parameters of the observer's pointing responses. Initiation times and the spatial parameters (angle of the hand trajectory) of the pointing movements were analysed. Results indicate that facilitation and IoR effects triggered by human and dot stimuli did not differ. Based on these findings, it seems that the crucial feature of motion cues that generate shifts in attention is biological motion, rather than human appearance per se.

生物运动在时间和空间运动参数中引起人与人之间的回归抑制

本研究旨在更深入地了解生物运动刺激的处理。为此,我们研究了返回抑制 (IoR) 效应是否出现在起始时间和指向左右空间中目标的指向运动轨迹中,其中先前的线索是指向人体模型或具有相同生物运动的点的运动. 目标随机出现在与运动提示方向相同或相反的一侧。假设视觉运动系统应该与点的生物运动产生共鸣,但人体模型应该夸大这种效果。因此,与点模型相比,人体模型应该触发更强的注意力转移,并在观察者的空间(运动)和时间参数中产生更强大的 IoR 效应。s 指向响应。分析了指向运动的启动时间和空间参数(手轨迹的角度)。结果表明,由人和点刺激触发的促进和 IoR 效应没有差异。基于这些发现,似乎产生注意力转移的运动线索的关键特征是生物运动,而不是人类外表本身。
