Two major functions of the visual system are discussed and contrasted. One function of vision is the creation of an internal model or percept of the external world. Most research in object perception has concentrated on this aspect of vision. Vision also guides the control of object-directed action. In the latter case, vision directs our actions with respect to the world by transforming visual inputs into appropriate motor outputs. We argue that separate, but interactive, visual systems have evolved for the perception of objects on the one hand and the control of actions directed at those objects on the other. This 'duplex' approach to high-level vision suggests that Marrian or 'reconstructive' approaches and Gibsonian or 'purposive-animate-behaviorist' approaches need not be seen as mutually exclusive, but rather as complementary in their emphases on different aspects of visual function.
本文讨论并对比了视觉系统的两个主要功能。视觉的一个功能是创建外部世界的内部模型或感知。物体感知方面的大多数研究都集中在视觉的这一方面。视觉还指导针对物体的动作控制。在后一种情况下，视觉通过将视觉输入转化为适当的运动输出，指导我们相对于世界的行动。我们认为，一方面，为了感知物体，另一方面，为了控制针对这些物体的行动，已经进化出了独立但相互作用的视觉系统。这种对高级视觉的“双重”方法表明，马尔理论或“重构性”方法与吉布森理论或“目的性-有生命-行为主义”方法不必被视为相互排斥，而应被视为在对视觉功能不同方面的强调上是互补的。
