Developmental dyslexia is primarily a reading disorder, but recent studies have indicated that face processing problems may also be present. Using a case-series approach, we tested face recognition and visual word recognition in 24 high school students diagnosed with developmental dyslexia. Contrary to previous findings, no face recognition problems were found on the group-level. Rather, a significant classical dissociation with impaired word reading and normal face recognition was demonstrated on a group-level and for six individuals with developmental dyslexia. However, four individuals with dyslexia did show face recognition problems. Thus, while problems in face recognition can be present in developmental dyslexia, the dissociation strongly suggests that face recognition can also be preserved. Combined with previously reported dissociations between face and word recognition in developmental prosopagnosia, this constitutes a double dissociation.

发展性阅读障碍中的人脸识别：人脸和单词之间分离的证据

发展性阅读障碍主要是一种阅读障碍，但最近的研究表明，面部处理问题也可能存在。我们使用案例系列方法测试了 24 名被诊断为发育性阅读障碍的高中生的面部识别和视觉单词识别。与之前的发现相反，在组级别上没有发现人脸识别问题。相反，在群体水平和六个患有发育性阅读障碍的个体中，表现出显着的经典分离与单词阅读障碍和正常面部识别。然而，四名患有阅读障碍的人确实出现了面部识别问题。因此，虽然人脸识别问题可能存在于发展性阅读障碍中，但这种分离强烈表明人脸识别也可以保留。
