One's being able to allocate attention to particular regions or properties of the visual field is fundamental to visual information processing. Visual attention determines what input is carefully analyzed and what input is more or less ignored. But at what stage of the visual system is this process evident? We describe three experiments that demonstrate an effect of voluntary spatial attention and voluntary object-based attention on an orientation illusion (the tilt aftereffect) that is believed to take place in primary visual cortex. This finding, in which selective visual attention influences adaptation to visual orientation information, contributes to mounting evidence for a view of visual perception in which mutual interaction takes place between high-level and low-level subsystems.
能够将注意力分配到视野的特定区域或属性是视觉信息处理的基础。视觉注意力决定了哪些输入会被仔细分析，哪些输入会或多或少被忽略。但在视觉系统的哪个阶段这个过程会明显体现呢？我们描述了三个实验，这些实验证明了自愿空间注意力和基于对象的自愿注意力对一种被认为发生在初级视觉皮层的方向错觉（倾斜后效）的影响。这一发现，即选择性视觉注意力会影响对视觉方向信息的适应，为一种视觉感知观点提供了越来越多的证据，即在高级和低级子系统之间会发生相互作用。
