如果像颜色和方向这样的特征在早期阶段1和2被大脑分别处理，那么大脑随后如何匹配正确的颜色和方向？我们发现，即使在极高的呈现率下，也可以报告方向与颜色或亮度的空间叠加配对，这表明这些特征在早期阶段就明确地组合编码，从而消除了任何后续信息绑定的需要。相比之下，报告空间上分离的特征配对需要慢一个数量级的速率，这表明感知这些配对需要在缓慢的注意阶段进行绑定。
If features such as color and orientation are processed separately by the brain at early stages 1, 2, how does the brain subsequently match the correct color and orientation? We found that spatially superposed pairings of orientation with either color or luminance could be reported even for extremely high rates of presentation, which suggests that these features are coded in combination explicitly by early stages, thus eliminating the need for any subsequent binding of information. In contrast, reporting the pairing of spatially separated features required rates an order of magnitude slower, suggesting that perceiving these pairs requires binding at a slow, attentional stage.
