两类手部动作表示被示出为通过监听可操纵对象的名称来激活（例如，手机）。与正确使用一个物体相关的功能性动作在它的名字出现后很快就被唤起，正如启动执行该动作所指示的那样。启动是持续整个词的发音时间。体积动作（那些用来简单地举起一个物体）在一个词的开头显示出负启动效应，然后是短暂的正启动效应。这种时间过程模式是由一个双过程机制，涉及额叶和顶叶解决候选运动反应之间的冲突。这两种类型的行动表示提出的概念知识的一部分，当遇到一个可操纵的对象的名称，虽然功能性的行动发挥了更核心的作用，在词汇概念的表示。
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.
