先前的研究表明，对动作的观察和动作的执行会激活常见的神经系统。最近，我们提供的数据显示，对抓握的动作观察启动了随后的执行（Castiello、Lusher、Mari、Edwards 和 Humphreys，2002）。在当前的论文中，我们研究了在启动项的大小不能预测目标的大小的情况下的动作启动（只有 20% 的试验是有效的）。我们证明了在这些条件下可靠的启动，与自动发生的效果一致。此外，即使观察者只看到物体而不是物体，我们也会显示启动作用以及启动试验中的伸手动作。我们讨论了与镜像神经元和物体可供性的作用相关的发现。 (C) 2003 Elsevier Inc. 保留所有权利。
Previous research has shown that the observation of actions and the execution of actions activate common neural systems. More recently, we have presented data showing that action observation of prehension primes subsequent execution (Castiello, Lusher, Mari, Edwards, & Humphreys, 2002). In the current paper we examined action priming under conditions in which the size of the prime did not predict the size of the target (only 20% of trials were valid). We demonstrated reliable priming under these conditions, consistent with the effect occurring automatically. In addition, we show priming even when observers saw just the object rather than the object and a reaching action on the prime trial. We discuss the findings in relation to the role of mirror neurons and object affordances. (C) 2003 Elsevier Inc. All rights reserved.
