对儿童面孔知觉的研究揭示了早期和面孔敏感的事件相关电位(ERP)成分的发展变化。孩子们在对他人的面孔感知和评价上也往往表现出种族偏见。目前的研究调查了儿童和成人中脸部敏感的早期ERPs如何受到脸部种族的影响。第二个目标考察了面孔识别熟练程度和隐性种族偏见与对自己和其他种族面孔的事件相关电位反应的关系。当高加索儿童和成人观看高加索人和东亚人的面孔时，记录脑电反应。参与者还完成了识别任务和与高加索人和东亚人面孔的内隐联想任务。其他人种面孔比自己人种面孔诱发的P100波幅更大。此外，与其他种族识别能力较差的成年人相比，其他种族识别能力较好的成年人对其他种族面孔的P100幅度反应更大。此外，在成年人中，更大的有利于自己种族的内隐偏见与更大的其他种族面孔的P100到N170峰间波幅相关。相比之下，在8到10岁的孩子中，更大的有利于自己种族的内隐偏见与更小的P100到N170峰间波幅有关，无论是自己的种族面孔还是其他种族的面孔。具有较好种族认知度的5至10岁儿童也显示出与年龄相关的P100至N170峰间波幅的下降。其他种族面孔的N170潜伏期随着年龄的增长而减少，这在其他种族识别能力较好的5至10岁儿童中也更加明显。因此，认知熟练程度和内隐种族偏见与成人和儿童早期的事件相关电位反应有关，但方式不同。
Studies examining children’s face perception have revealed developmental changes in early and face-sensitive event-related potential (ERP) components. Children also tend to show racial biases in their face perception and evaluation of others. The current study examined how early face-sensitive ERPs are influenced by face race in children and adults. A second objective examined face recognition proficiency and implicit racial bias in relation to ERP responses to own- and other-race faces. Electroencephalographic responses were recorded while Caucasian children and adults viewed Caucasian and East Asian faces. Participants also completed recognition tasks and an implicit association task with Caucasian and East Asian faces. Other-race faces elicited larger P100 amplitudes than own-race faces. Furthermore, adults with better other-race recognition proficiency showed larger P100 amplitude responses to other-race faces compared to adults with worse other-race recognition proficiency. In addition, larger implicit biases favoring own-race individuals were associated with larger P100 to N170 peak-to-peak amplitudes for other-race faces in adults. In contrast, larger implicit biases favoring own-race individuals were associated with smaller P100 to N170 peak-to-peak amplitudes for both own- and other-race faces in 8- to 10-year-olds. Five- to 10-year-olds with better own-race recognition also showed an age-related decrease in P100 to N170 peak-to-peak amplitudes for own-race faces. The age-related decrease in N170 latency for other-race faces was also more pronounced in 5- to 10-year-olds with better other-race recognition proficiency. Thus, recognition proficiency and implicit racial bias are associated with early ERP responses in adults and children, but in different ways.
