Clinical observation of performance on the Logical Memory (LM) and Visual Reproduction (VR) subtests from the WMS-III has revealed some variability in retention rates across stories and figures. This paper examined the degree to which this variability occurs in lateralized temporal lobe epilepsy (TLE) in comparison to a matched group from the WMS-III standardization sample, and explored whether analysis of qualitative aspects of LM and VR performance yield additional lateralizing information in TLE. Analysis of LM and VR scaled scores revealed differences between the TLE groups for LM, but not VR scores. All subjects benefited from repetition of LM Story B, with greater improvement in story retention in the Left versus Right TLE group. Variability in VR recall across figures was seen in all groups, with a bimodal distribution of retention rates for each figure and a sizable percentage of each group completely forgetting two or more figures. These results suggest that more careful analysis of individual LM story performance may be useful in some patients with TLE, whereas variability in VR retention across figures is common and should not be over interpreted.
对韦氏记忆量表第三版（WMS - III）中逻辑记忆（LM）和视觉再现（VR）子测验表现的临床观察显示，故事和图形的记忆保持率存在一定差异。本文研究了与WMS - III标准化样本中的匹配组相比，这种差异在颞叶癫痫（TLE）患者中出现的程度，并探讨了对LM和VR表现的定性分析是否能为TLE提供额外的定位信息。对LM和VR量表分数的分析显示，TLE组在LM分数上存在差异，但VR分数无差异。所有受试者重复LM故事B后都有获益，左颞叶癫痫组在故事记忆方面的改善比右颞叶癫痫组更大。所有组在VR图形回忆中都存在差异，每个图形的记忆保持率呈双峰分布，且每组中有相当比例的受试者完全忘记了两个或更多图形。这些结果表明，对某些TLE患者而言，更仔细地分析个体LM故事表现可能有用，而VR图形记忆保持的差异很常见，不应过度解读。
