研究已经说明了“认知”和“行动”系统之间的分离，表明不同的表征可能是现象体验和视觉运动行为的基础。然而，这些系统也相互作用。目前的研究表明，当一个对象的语义处理需要一个适当的动作时，一个必要的相互作用。实验1表明，语义任务干扰了手柄对物体的正确抓取，而视觉空间任务没有干扰。实验2评估了没有语义成分的视觉运动任务的表现，并显示了并发任务的效果逆转。在实验3中，并发词任务的变化表明语义信息的检索是适当掌握的必要条件。总之，如果没有语义处理，视觉运动系统可以指导对物体的有效抓取，但不是以适合其使用的方式。
Research has illustrated dissociations between "cognitive" and "action" systems, suggesting that different representations may underlie phenomenal experience and visuomotor behavior. However, these systems also interact. The present studies show a necessary interaction when semantic processing of an object is required for an appropriate action. Experiment 1 demonstrated that a semantic task interfered with grasping objects appropriately by their handles, but a visuospatial task did not. Experiment 2 assessed performance on a visuomotor task that had no semantic component and showed a reversal of the effects of the concurrent tasks. In Experiment 3, variations on concurrent word tasks suggested that retrieval of semantic information was necessary for appropriate grasping. In all, without semantic processing, the visuomotor system can direct the effective grasp of an object, but not in a manner that is appropriate for its use.
