Stroke patients were tested for their ability to recognize familiar objects shown in photographs, and we have confirmed previous reports that damage to the right hemisphere impairs recognition of objects shown at an "unusual angle". Additionally, these patients were impaired in matching unfamiliar (nonsense) objects which had been rotated. These impairments are discussed in the context of key task demands, particularly the need to extract depth cues from the photographs, and to rotate form elements to determine whether the samples provided different views of the same object. In the context of other work, these results suggest impairment of advanced perceptual skills which are needed to establish relationships of and among features of the forms.
对中风患者识别照片中熟悉物体的能力进行了测试，我们证实了之前的报告，即右脑损伤会损害对以“不寻常角度”呈现的物体的识别。此外，这些患者在匹配旋转过的不熟悉（无意义）物体时也存在障碍。在关键任务要求的背景下讨论了这些障碍，特别是从照片中提取深度线索以及旋转形状元素以确定所提供的样本是否展示了同一物体的不同视图的必要性。在其他研究的背景下，这些结果表明建立形状特征之间关系所需的高级感知技能受到了损害。
