Glyn Humphreys对注意和绑定的研究始于特征整合理论，该理论认为将视觉特征（如颜色和方向）结合在一起需要空间选择性注意。Humphreys采用了一个更具包容性的结合概念，并在神经心理学的基础上提出了对整个结合过程的多阶段描述，其中形式元素结合在一起之后是两个阶段的特征结合。只有特征结合的第二阶段，即从后顶叶皮层开始并返回早期视觉区域的再入（自上而下）过程，才需要注意。根据他对证据趋同的承诺，Humphreys认为调查注意在运动致盲中的作用可能是更好地理解注意依赖的第二阶段特征绑定的认知作用的途径。他认为，这种作用可能是为了解决歧义，并产生对知觉输入的单一一致的解释。
Glyn Humphreys' research on attention and binding began from feature-integration theory, which claims that binding together visual features, such as colour and orientation, requires spatially selective attention. Humphreys employed a more inclusive notion of binding and argued, on neuropsychological grounds, for a multi-stage account of the overall binding process, in which binding together of form elements was followed by two stages of feature binding. Only the second stage of feature binding, a re-entrant (top-down) process beginning in posterior parietal cortex and returning to early visual areas, required attention. In line with his commitment to converging evidence, Humphreys considered that investigating the role of attention in motion-induced blindness could be a route to better understanding of the cognitive role of the attention-dependent second stage of feature binding. He suggested that this role might be to resolve ambiguity and to generate a single consistent interpretation of the perceptual input.
