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.
研究了右脑和左脑损伤患者根据年龄对不熟悉面孔进行排序的能力，这些患者根据CT扫描结果分为后部损伤组和非后部损伤组。还进行了人脸识别测试和图形背景辨别测试。所有这三项测试都受到脑损伤的影响，但它们对损伤部位和损伤侧的敏感性各不相同。虽然在图形背景辨别测试中未发现半球差异，但面部年龄测试能显著区分右后部损伤患者与其他任何脑损伤组。人脸识别测试处于中间位置，与右非后部损伤患者相比，右后部损伤患者明显受损，与左后部损伤患者相比略有受损。失语症并未影响左脑损伤患者在任何一项测试中的表现。这些发现被解释为右后半球区域损伤会破坏视觉信息的结构编码的证据。还对四名面孔失认症患者进行了测试。只有那些表现出知觉性失认症迹象的患者在面部年龄测试中失败。
