Perceiving the environment automatically informs how we can interact with it through affordance mechanisms. However, it remains unknown how our knowledge about the environment shapes how it is perceived. In this training study, we evaluated whether motor and function knowledge about novel objects affects visual object processing. Forty-three participants associated a usage or function to a novel object in interactive virtual reality while their EEG was recorded. Both usage and function influenced the mu-band (8–12 Hz) rhythms, suggesting that motor and function object information influence motor processing during object recognition. Learning the usage also prevented the reduction of the theta-band (4–8 Hz) rhythms recorded over the posterior cortical areas, suggesting a predominant top-down influence of tool use information on visuo-motor pathways. The modulation being specifically induced by learning an object usage, the results support further the embodied cognition approach rather than the reasoning-based approach of object processing.

感知环境会自动告知我们如何通过可供性机制与之交互。然而，我们对环境的了解如何影响人们对环境的感知仍然未知。在这项培训研究中，我们评估了关于新物体的运动和功能知识是否会影响视觉物体处理。43 名参与者在记录他们的 EEG 时将一种用法或功能与交互式虚拟现实中的新对象相关联。使用和功能都会影响 mu-band (8–12 Hz) 节律，这表明运动和功能对象信息会影响对象识别过程中的运动处理。学习使用也阻止了记录在后皮质区域的 theta 波段（4-8 Hz）节律的减少，这表明工具使用信息对视觉运动通路的主要自上而下影响。
