处理面部信息的能力对于社交互动至关重要。以往的研究表明，成熟的人脸处理依赖于人脸特征和几何信息的提取。研究还表明，儿童获得这些处理技能的时间会延长。目前，人们对不同面部属性的处理顺序还不太了解。也就是说，虽然一些研究支持并行路线模型，该模型根据其可变性对不同的属性进行分组，但其他研究表明，特定的不变属性（如面部身份）可以作为解释更多动态方面（如面部表情或眼睛注视方向）的参考系。目前的研究测试了一种不同的方法，它提出了面对属性处理不同的任务要求。16名成年人做了一项相同-不同的任务，第二张脸可以在身份、表情或凝视方面与第一张脸不同，或者这些方面的任何组合。我们发现，反应时间增加和准确率下降时，身份被重复，这表明面部身份的变化是最显着的。最后，我们测试了两组7至8岁和10至11岁的儿童，发现那些特别依赖于面部信息处理策略的面部特征的准确率较低。这表明，虽然整体而言，脸处理策略是成人一样，从7岁，具体的脸属性的处理不断发展，整个童年中期。
The ability to process facial information is vital for social interactions. Previous research has shown that mature face processing depends on the extraction of featural and configural face information. It has been also shown that the acquisition of these processing skills is prolonged in children. The order in which different face properties are processed is currently less understood. Namely, while some research has supported a parallel-route model which groups different properties according to their variability, other studies have shown that specific invariant properties, such as facial identity, can serve as a reference frame for interpreting more dynamic aspects, such as facial expression or eye gaze direction. The current study tested a different approach, which proposes that face property processing varies with task requirements. Sixteen adults did a same-different task where the second face could differ from the first in the identity, expression, or gaze, or any combination of those. We found that reaction times increased and accuracy rates decreased when the identity was repeated, suggesting that changes in facial identity were the most salient ones. Finally, we tested two groups of 7-to 8- and 10- to 11-year-old children and found lower accuracy rates for those face properties that rely in particular on configural information processing strategies. This suggests that while overall, face processing strategies are adult-like from 7 years of age, the processing of specific face properties develops continuously throughout mid-childhood.
