全局形状是一种通过其特征的空间布置来描述对象的形式而不描述特征本身的外观的表示。在我们的观点论文[1]中，我们提出了腹侧视觉通路不代表全局形状信息，而是对局部特征的出现敏感的证据。根据最近的发现[2]，我们进一步认为，由于它更普遍地参与视觉空间处理，背侧视觉通路是计算物体特征之间关系和形成整体形状知觉的理想通路，这一假说的一个关键预测是背侧视觉通路受损的患者应该表现出整体形状知觉的缺陷，而腹侧视觉通路受损的患者应该表现出备用形状知觉感知能力然而，Goodale和米尔纳[3]正确地指出，在大多数情况下，背侧通路的损伤会导致视觉引导行动的缺陷，而腹侧通路的损伤会导致物体识别的缺陷。
Global shape is a representation that describes an object’s form via the spatial arrangement of its features without describing the appearance of the features themselves. In our Opinion paper [1], we presented evidence that the ventral visual pathway does not represent global shape information but is instead sensitive to the appearance of local features. On the basis of recent findings [2], we further argued that, because of its involvement in visuospatial processing more generally, the dorsal visual pathway is ideally suited to compute the relations among object features and form global shape percepts.A key prediction of this hypothesis is that patients with damage to the dorsal pathway should exhibit deficits in perceiving global shape and patients with ventral damage should exhibit spared shape perception abilities. However, Goodale and Milner [3] rightly point out that, in the majority of cases, damage to the dorsal pathway causes deficits in visually guided action, whereas damage to the ventral pathway causes deficits in object recognition.
