A neglected topic in metamemory research is the ability of subjects to predict their own recognition performance for faces. We investigated whether subjects can make such judgments of learning (JOL) for unfamiliar faces and whether JOLs relate to facial distinctiveness, a powerful determinant of face recognition. One group of subjects made JOLs, and a second group rated the same faces for distinctiveness; subsequently, both groups tried to recognize these faces among new faces. There was significant prospective metamemory for faces that appeared to be based on facial distinctiveness. Both prospective metamemory and distinctiveness ratings related to long-lasting effects in event-related brain potentials (ERPs), closely resembling an ERP component that predicted face recognition. Therefore, the brain processes underlying JOLs, distinctiveness, and recognition memory for faces appear to be intimately related.
元记忆研究中一个被忽视的主题是受试者预测自己对面部识别表现的能力。我们研究了受试者是否能够对不熟悉的面孔做出这种学习判断（JOL），以及JOL是否与面部独特性相关，面部独特性是人脸识别的一个重要决定因素。一组受试者做出JOL，另一组对相同面孔的独特性进行评分；随后，两组都试图在新面孔中识别这些面孔。对于似乎基于面部独特性的面孔，存在显著的前瞻性元记忆。前瞻性元记忆和独特性评分都与事件相关脑电位（ERP）中的长期效应相关，与预测人脸识别的ERP成分非常相似。因此，JOL、独特性和面部识别记忆背后的大脑过程似乎密切相关。
