We report a new case of visual associative agnosia. Our patient (DJ) was impaired in several tasks assessing visual processing of real objects, colour pictures, and line drawings. The deficit was present both with naming and gesturing responses. Object processing in other modalities (verbal, auditory nonverbal, and tactile) was intact. Semantic processing was impaired in the visual but not in the verbal modality. Picture-word matching was better than single picture identification. DJ's visual perceptual processing, was intact in several tasks such as visual attributes discrimination, shape discrimination, illusory contours perception, segmentation, embedded figures processing and matching objects under different viewpoints. Most importantly, we show that there was no impairment of stored structural descriptions and that the patient was able to build new visual representations. These results are considered in the context of Farah's (1990, 1991) proposals about visual associative agnosia.
我们报告了一例新的视觉联想性失认症病例。我们的患者（DJ）在多项评估真实物体、彩色图片和线条图视觉处理的任务中存在障碍。这种缺陷在命名和手势反应中都存在。其他模态（言语、听觉非言语和触觉）的物体处理完好无损。视觉语义处理受损，但言语模态未受损。图片-文字匹配优于单一图片识别。DJ 在多项任务中的视觉知觉处理完好无损，例如视觉属性辨别、形状辨别、错觉轮廓感知、分割、嵌入式图形处理和在不同视角下匹配物体。最重要的是，我们表明患者没有存储结构描述的损伤，并且能够建立新的视觉表示。这些结果在 Farah（1990，1991）关于视觉联想性失认症的建议的背景下进行了考虑。
