两个实验探讨了语言理解对示能性的影响。参与者阅读一个由观察或动作动词（看/抓）后跟一个物体名称组成的句子。他们必须判断句子后面的视觉对象是否与句子中提到的对象相同。无论是精度或电力握可抓取的对象呈现在一个方向提供的行动（规范）或没有。动作句比观察句快，有力握物体比精确握物体快。此外，更快的RT时，获得定向提供的行动。结果表明，在语言理解过程中激活的模拟导致了对象的“运动原型”的形成。该运动原型编码关于临时/规范和稳定的可供性的信息（例如，方向，大小），这可能涉及到不同的认知和神经系统（背侧，腹侧系统）。(C)2008 Elsevier B. V.保留所有权利。
Two experiments investigate the effects of language comprehension on affordances. Participants read a sentence composed by either an observation or an action verb (Look at/Grasp) followed by an object name. They had to decide whether the visual object following the sentence was the same as the one mentioned in the sentence. Objects graspable with either a precision or a power grip were presented in an orientation affording action (canonical) or not. Action sentences were faster than observation sentences, and power grip objects were faster than precision grip objects. Moreover, faster RTs were obtained when orientation afforded action. Results indicate that the simulation activated during language comprehension leads to the formation of a "motor prototype" of the object. This motor prototype encodes information on temporary/canonical and stable affordances (e.g., orientation, size), which can be possibly referred to different cognitive and neural systems (dorsal, ventral systems).
