有证据表明，当一个对象的一个功能是专门出席，该对象的其他任务无关的功能也收到增强处理，大概是由于自动绑定过程。另一方面，证据也表明，注意力可以选择性地偏向于处理一个特征，而牺牲处理其他特征。因此，绑定调用相关功能的组合处理，而选择性注意强调差异处理。我们假设，约束性和选择性的基于特征的注意力取决于一个共同的资源，因此可能会显示干扰效应。目前的研究通过操纵绑定需求来测试这一点，而人类参与者则将注意力集中在移动随机点刺激的颜色或运动上。反应时间的措施表明，有偏见的注意力的影响减少时，约束力的要求增加。这一发现支持的论点，约束力依赖于，至少部分地，在相同的机制所援引的准备偏置的选择性注意。
Evidence indicates that when one feature of an object is specifically attended, other task-irrelevant features of that object also receive enhanced processing, presumably as a result of automatic binding processes. On the other hand, evidence also shows that attention can be selectively biased in favor of processing one feature at the expense of processing others. Thus, binding invokes combinatorial processing of related features whereas selective attention emphasizes differential processing. We hypothesized that binding and selective feature-based attention depend on a common resource and therefore might show interference effects. The current study tested this by manipulating binding demands while human participants directed their attention to the color or motion of moving random dot stimuli. Response time measures showed that effects of biased attention were reduced when binding demands were increased. This finding supports the thesis that binding relies, at least in part, upon the same mechanisms invoked by preparatory biasing of selective attention.
