Perception and action in human visual behaviour

人类无时无刻不在与物体互动。 视觉是最常用于获取有关物体的信息的感觉。 尽管在过去的十年里，我们已经学到了很多关于视觉控制动作的知识，但我们仍然远远没有完全理解。 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，知觉错觉通常不会影响我们的行动，即使它们在我们对目标物体特征的感知中产生偏见。 然而，当人们与视线被阻挡的物体互动时，或者当人们闭上一只眼睛时，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重要。 在这里进行的研究将有助于理解有意识的感知和视觉控制之间的复杂相互作用。 对这些相互作用的基本理解可能有助于为那些患有视觉或神经系统疾病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.
