人们如何表征物体的意义？现在，考虑可操纵的物体（例如，铅笔）激活大脑区域的潜在行动。但是，这种激活是这些对象的意义的一部分，还是仅仅是偶然的？我们在这里报告的研究表明，当手从事的任务涉及的运动与那些用来与频繁操作的对象进行交互的运动不兼容时，更难思考这些对象，但不难思考不经常操作的对象（例如，书架）。重要的是，对对象的手动经验量决定了干扰量。这些发现表明，大脑活动背后的手动操作是一部分，而不是外围的，经常操纵的对象的代表。此外，他们认为，人们思考一个物体的能力是动态变化的，这取决于他们对物体意义的（基于经验的）心理表征与他们当时正在做的事情之间的匹配。
How do people represent object meaning? It is now uncontentious that thinking about manipulable objects (e.g., pencils) activates brain regions underlying action. But is this activation part of the meaning of these objects, or is it merely incidental? The research we report here shows that when the hands are engaged in a task involving motions that are incompatible with those used to interact with frequently manipulated objects, it is more difficult to think about those objects—but not harder to think about infrequently manipulated objects (e.g., bookcases). Critically, the amount of manual experience with the object determines the amount of interference. These findings show that brain activity underlying manual action is part of, not peripheral to, the representation of frequently manipulated objects. Further, they suggest that people’s ability to think about an object changes dynamically on the basis of the match between their (experience-based) mental representation of its meaning and whatever they are doing at that moment.
