虽然大多数关于视觉注意的研究都考察了在视野中不同位置之间转移注意力的效果，但注意力也可以被引导到特定的视觉特征，如颜色，方向或运动方向。单单位研究表明，对一个特征的注意力会调节猴子视觉皮层一系列区域的神经元信号。基于特征的注意力的位置无关属性使得它特别适合于选择性地修改与当前关注的特征相匹配的复杂视觉场景中的刺激或部分的神经表征。这篇评论是TINS关于认知神经基质的特刊的一部分。
Although most studies of visual attention have examined the effects of shifting attention between different locations in the visual field, attention can also be directed to particular visual features, such as a color, orientation or a direction of motion. Single-unit studies have shown that attention to a feature modulates neuronal signals in a range of areas in monkey visual cortex. The location-independent property of feature-based attention makes it particularly well suited to modify selectively the neural representations of stimuli or parts within complex visual scenes that match the currently attended feature. This review is part of the TINS special issue on The Neural Substrates of Cognition.
