Perception and action in human visual behaviour

人类每时每刻都在与物体互动。视觉是最常用来获取物体信息的感觉。尽管在过去的十年里，我们已经了解了很多关于视觉控制动作的知识，但我们还远远没有完全理解。有趣的是，研究表明，我们对物体的感知与我们与这些物体互动的能力截然不同。例如，感知错觉通常不会影响我们的行为，尽管它们会使我们对目标物体特征的感知产生偏差。然而，当人们与被遮挡在视线之外的物体或闭着一只眼睛观看的物体互动时，情况就会发生变化。在这些情况下，对物体的感知似乎对指导行动更为重要。在这里进行的研究将有助于理解意识知觉和动作视觉控制之间复杂的相互作用。对这些相互作用的基本理解可能有助于为治疗视觉或神经障碍患者的康复治疗师提供指导。

Humans interact with objects all the time. Vision is the sense that is most commonly used to acquire information about objects. Although we have learned a great deal about the visual control of action over the last decade, we are still far from a complete understanding. Interestingly, research has shown that our perception of objects is quite distinct from our ability to interact with those objects. For example, perceptual illusions do not typically affect our actions even though they create biases in our perception of the target object's features. The situation changes, however, when people interact with objects that are blocked from view, or that are viewed with one eye closed. In these situations, perception of the object seems to be more important for guiding action. The studies to be carried out here will help to understand the complex interactions between conscious perception and visual control of action. Fundamental understanding of these interactions may help to provide guidance to rehabilitation therapists working with individuals who have visual or neurological disorders.
