面容失认症是指在没有感觉或智力障碍的情况下，无法仅凭面部识别某人。与获得性面孔失认症相比，我们研究了先天性面孔失认症。由于我们最近可以证明这种形式是作为一种简单的单基因性状遗传的，我们称之为遗传形式。为了确定面部识别和神经元处理以及面部信息的感知获取是否与面孔失认症有关，我们研究了四种遗传性面孔失认症患者的凝视行为，并将其与匹配的对照组进行了比较。这种很少被研究的面容失认症确保缺陷仅限于面部识别。对照组的参与者将目光集中在面部的中心特征上，而遗传性面孔失认症的参与者则表现出明显不同的凝视行为。他们的目光更分散，也更关注外部面部特征。因此，遗传性面孔失认症患者的面部识别障碍反映在他们的注视行为上。
Prosopagnosia is the inability to recognize someone by the face alone in the absence of sensory or intellectual impairment. In contrast to the acquired form of prosopagnosia we studied the congenital form. Since we could recently show that this form is inherited as a simple monogenic trait we called it hereditary form. To determine whether not only face recognition and neuronal processing but also the perceptual acquisition of facial information is specific to prosopagnosia, we studied the gaze behaviour of four hereditary prosopagnosics in comparison to matched control subjects. This rarely studied form of prosopagnosia ensures that deficits are limited to face recognition. Whereas the control participants focused their gaze on the central facial features, the hereditary prosopagnosics showed a significantly different gaze behaviour. They had a more dispersed gaze and also fixated external facial features. Thus, the face recognition impairment of the hereditary prosopagnosics is reflected in their gaze behaviour.
