整体面孔加工的一个特点是不能选择性地关注I面孔部分而忽略另一部分的信息。在3个连续匹配实验中，作者通过测量空间对齐或脱节配置中显示的线索和未线索复合半脸之间的一致性效应，测试了整体处理的知觉和决策帐户。作者发现，当研究脸的上半部分和下半部分在空间上对齐，错位（实验1），或彼此相邻（实验2）时，一致性效应。然而，在测试中，一致性效应因未对齐而减少，并在相邻配置中消失。这表明，在测试中的操作比在学习中的操作更有影响力，与整体处理的决策帐户一致。当编码需求的研究和测试的面孔等同（实验3），作者观察到的研究配置的影响表明，与感性的解释，编码的影响幅度的整体处理。总之，这些结果不能占目前的知觉或决策帐户的整体处理，并建议存在一个注意力依赖的机制，可以整合空间上分离的脸部分。
One hallmark of holistic face processing is an inability to selectively attend to I face part while ignoring information in another part. In 3 sequential matching experiments, the authors tested perceptual and decisional accounts of holistic processing by measuring congruency effects between cued and uncued composite face halves shown in spatially aligned or disjointed configurations. The authors found congruency effects when the top and bottom halves of the study face were spatially aligned, misaligned (Experiment 1), or adjacent to one another (Experiment 2). However, at test, congruency effects were reduced by misalignment and abolished for adjacent configurations. This suggests that manipulations at test are more influential than manipulations at study, consistent with a decisional account of holistic processing. When encoding demands for study and test faces were equated (Experiment 3), the authors observed effects of study configuration suggesting that, consistent with a perceptual explanation, encoding does influence the magnitude of holistic processing. Together, these results cannot be accounted for by current perceptual or decisional accounts of holistic processing and suggest the existence of an attention-dependent mechanism that can integrate spatially separated face parts.
