There is converging evidence for the presence of a fast subcortical face-processing route that operates on global face characteristics in the mature brain. Until now, little has been known about the development of such a route, which is surprising given suggestions that this fast subcortical face-processing route might be affected in neurodevelopmental disorders such as autism. To address this, early visual event-related potentials to pictures of fearful and neutral faces containing detailed or global information in 3- to 4-year-old (n = 20), 5- to 6-year-old (n = 25), and 7- to 8-year-old (n = 25) children were compared. In children, emotional processing was driven by detailed information. Developmental effects are discussed in terms of maturation of the fast subcortical face-processing route as well as an increase in experience with facial expressions with age.
越来越多的证据表明，成熟大脑中存在一条快速的皮质下面部处理途径，该途径对全局面部特征起作用。到目前为止，人们对这样一条途径的发展知之甚少，这令人惊讶，因为有研究表明，这种快速的皮质下面部处理途径可能会受到自闭症等神经发育障碍的影响。为了解决这个问题，我们比较了 3 至 4 岁（n=20）、5 至 6 岁（n=25）和 7 至 8 岁（n=25）儿童对包含详细或全局信息的恐惧和中性面孔图片的早期视觉事件相关电位。在儿童中，情绪处理是由详细信息驱动的。我们将从快速皮质下面部处理途径的成熟以及随着年龄的增长对面部表情经验的增加的角度来讨论发展效应。
