The success of visuomotor interactions in everyday activities such as grasping or sliding a cup is inescapably governed by the laws of physics. Research on intuitive physics has predominantly investigated reasoning about objects' behaviour involving binary forced choice responses. We investigated how the type of visuomotor response influences participants' beliefs about physical quantities and their lawful relationship implicit in their active behaviour. Participants propelled pucks towards targets positioned at different distances. Analysis with a probabilistic model of interactions showed that subjects adopted the non-linear control prescribed by Newtonian physics when sliding real pucks in a virtual environment even in the absence of visual feedback. However, they used a linear heuristic when viewing the scene on a monitor and interactions were implemented through key presses. These results support the notion of probabilistic internal physics models but additionally suggest that humans can take advantage of embodied, sensorimotor, multimodal representations in physical scenarios.
在诸如抓取或滑动杯子等日常活动中,视觉运动交互的成功必然受物理定律支配。直观物理学的研究主要调查了涉及二元强制选择反应的物体行为推理。我们研究了视觉运动反应类型如何影响参与者对物理量的信念以及他们在主动行为中隐含的合法关系。参与者将冰球推向位于不同距离的目标。用交互概率模型进行的分析表明,即使在没有视觉反馈的情况下,当在虚拟环境中滑动真实冰球时,受试者采用了牛顿物理学规定的非线性控制。然而,当在显示器上观看场景并通过按键实现交互时,他们使用了线性启发式方法。这些结果支持概率性内部物理模型的概念,但此外还表明,人类可以在物理场景中利用具身的、感觉运动的、多模态的表征。
