AG, a pure case of optic anomia (object naming impaired; action naming good) is described. We consider the fit of experimental data from AG to different theoretical accounts of optic aphasia. Overall, we find no evidence for impairments intrinsic to semantic representations, but we note a number of problems that we interpret as indicating a slight, and specific, weakness in semantic access from vision. We also note a mild problem in generating names to a cue (verbal fluency). The main aim of the report was to provide a full description of tests of visual, semantic, and speech output skills in this patient in relation to the processing of visually presented objects and scenes, within a sequential information processing account which enables some theoretical implications to be drawn, albeit not conclusively.
本文描述了AG这一单纯性视觉失认症病例（物体命名受损；动作命名正常）。我们考察了来自AG的实验数据与视觉性失语症不同理论解释的契合度。总体而言，我们没有发现语义表征内在受损的证据，但我们注意到一些问题，我们将其解释为表明从视觉中进行语义提取存在轻微且特定的缺陷。我们还注意到在根据提示生成名称（言语流畅性）方面存在一个轻微问题。本报告的主要目的是在一个顺序信息处理框架内，全面描述该患者在处理视觉呈现的物体和场景时的视觉、语义和言语输出技能测试，这使得我们能够得出一些理论启示，尽管并非结论性的。
