研究人员对右脑和左脑受损的患者按年龄对未知面孔进行排序的能力进行了研究，并根据 CT 扫描结果分为后部组和非后部组。还进行了人脸识别测试和图形背景辨别测试。所有三项测试均受到脑损伤的影响，但它们对病变部位和侧面的敏感性各不相同。虽然在图形地面辨别测试中没有发现半球差异，但面部年龄测试显着区分了右后损伤患者和任何其他脑损伤组。面部识别测试处于中间位置，与右侧非后部患者相比，右后部患者明显受损，而与左后部患者相比，右后部患者略有受损。失语症不会影响左脑受损患者在任何测试中的表现。这些发现被解释为证据，表明右后半球区域的损伤破坏了视觉信息的结构编码。还测试了四名面盲症患者。只有那些表现出统觉失认迹象的人才能在面部年龄测试中失败。
The ability to order unknown faces by age was investigated in right and left brain-damaged patients, divided into posterior and non-posterior groups on the basis of CT scan findings. A face recognition test and a figure ground discrimination test were also given. All three tests were affected by brain damage, but their sensitivity to the locus and side of lesion varied. While no hemispheric difference was found on the figure ground discrimination test, the face age test significantly discriminated patients with right posterior injury from any other brain-damaged group. The face recognition test occupied an intermediate position, with right posterior patients significantly impaired in comparison with right non-posterior patients and marginally impaired with respect to left posterior patients. Aphasia did not affect the performance of left brain-damaged patients on any of the tests. The findings are interpreted as evidence that damage of the right posterior hemisphere areas disrupts the structural encoding of visual information. Four prosopagnosic patients were also tested. Only those showing signs of apperceptive agnosia failed on the face age test.
