Object individuation: is the process whereby the brain infers that dynamic input reflects multiple discrete objects, rather than a single, continuing object over time. Object substitution masking: is a popular method for operationalizing object individuation inferences in the laboratory. Although object substitution masking was historically thought to interact with attentional processes, an emerging body of literature indicates that this form of visual masking is impervious to some attentional manipulations. However, one form of attention that has not been systematically studied in relation to object-substitution masking is endogenous attentional orienting. This is important because in other domains, endogenous attentional orienting has been found to have qualitatively distinct effects from other forms of attention, including impacting visual perception when other forms of attention do not. Therefore, if attention does interact with object individuation processes, then endogenous attentional orienting is the most likely candidate mechanism for such a relationship. Here, therefore, the impact of endogenous attentional on object-substitution masking was tested. Across 2 experiments, although endogenous attentional orienting impacted overall target perception, it had no impact on object substitution masking. This implies that object individuation inferences are indeed independent of attention. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
是指大脑推断动态输入反映多个离散客体，而不是随时间推移单一、连续客体的过程。客体替换掩蔽：是一种在实验室中操作客体分辨推断的常用方法。尽管客体替换掩蔽在历史上被认为与注意过程相互作用，但越来越多的文献表明，这种形式的视觉掩蔽不受某些注意操作的影响。然而，一种与客体替换掩蔽没有系统研究的注意力形式是内源性注意定向。这很重要，因为在其他领域，内源性注意定向已被发现与其他形式的注意力具有截然不同的影响，包括在其他形式的注意力不影响视觉感知时产生影响。因此，如果注意力确实与客体分辨过程相互作用，那么内源性注意定向是这种关系的最可能机制。因此，本文测试了内源性注意对客体替换掩蔽的影响。在 2 项实验中，尽管内源性注意定向确实影响了整体目标感知，但它对客体替换掩蔽没有影响。这意味着客体分辨推断确实独立于注意。（APA，2019）
