视觉体验的内容取决于选择性注意力在视野中的分布。我们使用功能性磁共振成像（fMRI）来测试基于特征的注意力是否可以全面影响视觉皮层对被关注位置以外刺激的反应。注意刺激特征（颜色或运动方向）增加了皮层视觉区域对空间上遥远的、被忽略的具有相同特征的刺激的反应。
The content of visual experience depends on how selective attention is distributed in the visual field. We used functional magnetic resonance imaging (fMRI) in humans to test whether feature-based attention can globally influence visual cortical responses to stimuli outside the attended location. Attention to a stimulus feature (color or direction of motion) increased the response of cortical visual areas to a spatially distant, ignored stimulus that shared the same feature.
