三个年龄组的参与者(5-6岁，7-8岁，成年人)根据面部认同感匹配面部。该过程包括低通或高通过滤的人脸或由与不同空间带宽相关联的两个人脸组成的混合人脸。比较刺激为未过滤的面孔。在三个年龄组中，数据表明优先处理低通信息有显著的偏见。在第二个任务中，参与者被要求识别混合高分/低分面孔的情绪(微笑或做鬼脸)或性别(男性或女性)。不同年龄段的两个任务都出现了相反的结果；性别歧视任务表明偏向低通信息，而情绪任务表明偏向高通信息。这些差异表明，情绪、性别和身份等不同功能类型的信息具有独立的加工路径。这些路线在5岁时就已经建立起来了。(C)2004 Elsevier Inc.保留所有权利。
Three age groups of participants (5-6 years, 7-8 years, adults) matched faces on the basis of facial identity. The procedure involved either low- or high-pass filtered faces or hybrid faces composed from two faces associated with different spatial bandwidths. The comparison stimuli were unfiltered faces. In the three age groups, the data indicated a significant bias for processing of low-pass information in priority. In a second task, participants were asked to identify the emotion (smiling or grimacing) or gender (male or female) of hybrid high-pass/low-pass faces. Opposite results emerged in the two tasks irrespective of the age group; the gender discrimination task indicated a bias for low-pass information, and the emotion task indicated a bias for high-pass information. These differences suggest independent processing routes for functionally different types of information such as emotion, gender, and identity. These routes are already established by 5 years of age.
