Patients with lesions to either the right or left hemisphere and control subjects were asked to discriminate photographs of faces and then to sort these photographs according to the identity of the face or the emotion displayed. Whether identity and emotion were correlated, independent, or constant was varied across trials. Patients with right hemisphere damage were significantly impaired at discriminating both identity and expression, and at selectively attending to either sort of facial information. However, these subjects could selectively attend to attributes of geometric figures suggesting that their impairment with faces cannot be attributed to deficits in selective attention in general.
患有右侧或左侧半球损伤的患者以及对照组受试者被要求辨别面部照片，然后根据面部的身份或所显示的情绪对这些照片进行分类。身份和情绪是相关、独立还是恒定的，在不同试验中有所变化。右侧半球损伤的患者在辨别身份和表情以及选择性地关注任何一种面部信息方面均有显著受损。然而，这些受试者能够选择性地关注几何图形的属性，这表明他们对面部的损伤不能归因于一般的选择性注意力缺陷。
