In this paper, we propose that the debate concerning the locus of attentional selection can be resolved by specifying the conditions under which early selection is possible. In the first part, we present a theoretical discussion that integrates aspects from structural and capacity approaches to attention and suggest that perceptual load is a major factor in determining the locus of selection. In the second part, we present a literature review that examines the conditions influencing the processing of irrelevant information. This review supports the conclusion that a clear physical distinction between relevant and irrelevant information is not sufficient to prevent irrelevant processing; early selection also requires that the perceptual load of the task be sufficiently high to exceed the upper limit of available attentional resources.
在本文中，我们提出，关于注意力选择位点的争论可以通过明确早期选择得以发生的条件来解决。在第一部分，我们进行了理论探讨，整合了注意力的结构和容量方法的各个方面，并指出知觉负载是决定选择位点的一个主要因素。在第二部分，我们进行了文献综述，考察了影响无关信息加工的条件。这一综述支持了以下结论：相关信息和无关信息之间清晰的物理区分不足以防止无关信息的加工；早期选择还要求任务的知觉负载足够高，以超过可用注意力资源的上限。
