V.Goffaux和B.Rossion(2006)认为，人脸的整体加工在很大程度上受到低空间频率(LSF)的支持，但高空间频率(HSF)支持较少。我们使用面孔组合的顺序匹配任务解决了这一问题。观察者判断对准或未对准的复合材料的上半部分是否相同。我们复制了V.Goffaux和B.Rossion(2006)的结果，发现与相同试验中的HSF Face相比，LSF在准确性上具有更大的比对效果。然而，与LSF Face相比，HSF对“相同”的反应也有更大的偏向，这表明对齐效应源于不同的反应偏向。至关重要的是，LSF和HSF的相似一致性效应表明，LSF和HSF的面孔被同等整体地处理。这些结果表明，为了充分理解面孔加工的整体性，有必要使用考虑反应偏差的措施。
V. Goffaux and B. Rossion (2006) argued that holistic processing of faces is largely supported by low spatial frequencies (LSFs) but less so by high spatial frequencies (HSFs). We addressed this claim using a sequential matching task with face composites. Observers judged whether the top halves of aligned or misaligned composites were identical. We replicated the V. Goffaux and B. Rossion (2006) results, finding a greater alignment effect in accuracy for LSF compared with HSF faces on same trials. However, there was also a greater bias for responding "same" for HSF compared with LSF faces, indicating that the alignment effects arose from differential response biases. Crucially, comparable congruency effects found for LSF and HSF suggest that LSF and HSF faces are processed equally holistically. These results demonstrate that it is necessary to use measures that take response biases into account in order to fully understand the holistic nature of face processing.
