The Smeets and Brenner view on grasping is simple: grasping is in fact pointing. In our comments we examine the model beyond the reach-to-grasp task, namely, by grasping (without reaching) of moving objects and eating. The model fits the data of both tasks. Although generalization of a model to different tasks usually strengthens its acceptance, in the present case it reveals its shortcomings, namely, both tasks include a clear grasping component that is hard to accept as pointing.
抓握实际上就是指物。在我们的评论中，我们考察了超出伸手抓握任务范围的该模型，即通过抓握（不伸手）移动的物体以及进食来考察。该模型与这两项任务的数据都相符。虽然将一个模型推广到不同任务通常会增强其被接受程度，但在当前这种情况下却揭示了它的缺点，即这两项任务都包含一个明显的抓握成分，而这很难被当作指物来接受。
