本研究采用视觉诱发事件相关电位（ERP）的方法来研究结构和更高层次的面孔处理的时间模式，在出生和寄养/养母观看他们的孩子的照片。14名生母和14名养母/养母参与了一项计算机化的任务，在这项任务中，她们观看了自己孩子的面部照片，以及熟悉和不熟悉的儿童和成人的面部照片。所有的母亲，无论类型，显示ERP模式提示增加注意力分配到自己的孩子的脸相比，其他儿童和成人的面孔开始早在100-150毫秒刺激后开始，并持续数百毫秒。这些数据符合并行处理模型，该模型假定多个大脑区域参与同时编码面部的结构特征及其情感和个人意义。此外，后期积极的ERP模式与更大的分配的注意力预测母亲的亲子关系的看法，积极的和有影响力的孩子的心理发展。这些研究结果表明，使用ERP组件的潜在效用，以指数产妇的过程。
This study employed visually evoked event-related potential (ERP) methodology to examine temporal patterns of structural and higher-level face processing in birth and foster/adoptive mothers viewing pictures of their children. Fourteen birth mothers and 14 foster/adoptive mothers engaged in a computerized task in which they viewed facial pictures of their own children, and of familiar and unfamiliar children and adults. All mothers, regardless of type, showed ERP patterns suggestive of increased attention allocation to their own children’s faces compared to other child and adult faces beginning as early as 100–150 ms after stimulus onset and lasting for several hundred milliseconds. These data are in line with a parallel processing model that posits the involvement of several brain regions in simultaneously encoding the structural features of faces as well as their emotional and personal significance. Additionally, late positive ERP patterns associated with greater allocation of attention predicted mothers’ perceptions of the parent–child relationship as positive and influential to their children’s psychological development. These findings suggest the potential utility of using ERP components to index maternal processes.
