In visual search, both attentional and non-attentional sensory processes contribute to set-size effects. Here, non-attentional sensory effects were controlled and the remaining effects matched closely the purely attentional effects measured by a cueing paradigm. Using these controls, set-size effects were measured for five simple and two more complex tasks. The set-size effects were of similar magnitude for all of the simple tasks and larger for the complex tasks. For stimuli in the simple tasks, the results were consistent with the existence of a purely attentional effect on decision processing that is independent of the particular stimulus.
在视觉搜索中，注意力和非注意力感觉过程都会对集合大小效应产生影响。在此，非注意力感觉效应得到了控制，其余效应与通过提示范式测量的纯注意力效应密切匹配。利用这些控制措施，对五个简单任务和两个更复杂的任务进行了集合大小效应的测量。所有简单任务的集合大小效应幅度相似，而复杂任务的效应则更大。对于简单任务中的刺激，结果与决策过程中存在独立于特定刺激的纯注意力效应相一致。
