Recent findings suggest that visuomotor performance is modulated by people's beliefs about the agency (e.g., animate vs. inanimate) behind the events they perceive. This study investigated the effect of instructed agency on ocular tracking of point-light motions with biological and nonbiological velocity profiles. The motions followed either a relatively simple (ellipse) or a more complex (scribble) trajectory, and agency was manipulated by informing the participants that the motions they saw were either human or computer generated. In line with previous findings, tracking performance was better for biological than for nonbiological motions, and this effect was particularly pronounced for the simpler (elliptical) motions. The biological advantage was also larger for the human than for the computer instruction condition, but only for a measure that captured the predictive component of smooth pursuit. These results suggest that ocular tracking is influenced by the internal forward model people choose to adopt.
最近的研究结果表明，人们对事件背后的主体（例如，有生命的还是无生命的）的信念会影响运动知觉表现。本研究通过指示主体来调查被试对具有生物和非生物速度曲线的光点运动的眼动跟踪的影响。这些运动遵循相对简单（椭圆）或更复杂（涂鸦）的轨迹，通过告知参与者他们所看到的运动是人为的还是计算机生成的来操纵主体。与之前的发现一致，生物运动比非生物运动的跟踪表现更好，并且这种效应对于更简单（椭圆）的运动尤为明显。对于人类指令条件，生物优势也大于计算机指令条件，但仅适用于捕捉平滑追踪预测成分的度量。这些结果表明，眼动跟踪受到人们选择采用的内部前馈模型的影响。
