Two classes of hand action representations are shown to be activated by listening to the name of a manipulable object (e.g., cellphone). The functional action associated with the proper use of an object is evoked soon after the onset of its name, as indicated by primed execution of that action. Priming is sustained throughout the duration of the word's enunciation. Volumetric actions (those used to simply lift an object) show a negative priming effect at the onset of a word, followed by a short-lived positive priming effect. This time-course pattern is explained by a dual-process mechanism involving frontal and parietal lobes for resolving conflict between candidate motor responses. Both types of action representations are proposed to be part of the conceptual knowledge recruited when the name of a manipulable object is encountered, although functional actions play a more central role in the representation of lexical concepts.
两类手部动作表示在听到可操作对象（例如手机）的名称时被激活。与正确使用对象相关的功能动作在对象名称出现后很快被激发，这表现为该动作的预先执行。在单词发音的整个过程中，这种启动都会持续。体积动作（用于简单提起物体的动作）在单词开始时会产生负启动效应，随后会产生短暂的正启动效应。这种时间进程模式可以用一个双过程机制来解释，该机制涉及额叶和顶叶，用于解决候选运动反应之间的冲突。这两种类型的动作表示都被提议作为遇到可操作对象的名称时所涉及的概念知识的一部分，尽管功能动作在词汇概念的表示中起着更核心的作用。
