This article reports evidence that two variables--object viewpoint and semantic priming--differentially affect action and semantic decisions to objects. Changing the viewing angle of an object, so that its graspable parts are oriented away from observers, disrupted action decisions but had little effect on semantic categorization. In contrast, semantic priming influenced semantic categorization and object naming, but not action decisions. Action priming, however, did not affect performance. These selective effects are consistent with the existence of separate semantic and direct (nonsemantic) routes to action from vision.
本文报告了证据表明两个变量——物体视角和语义启动——对物体的动作和语义决策有不同影响。改变物体的视角，使其可抓握部分背离观察者，会干扰动作决策，但对语义分类影响不大。相比之下，语义启动影响语义分类和物体命名，但不影响动作决策。然而，动作启动并未影响表现。这些选择性效应与从视觉到动作存在独立的语义和直接（非语义）路径相一致。
