我们检测了威斯康星州卡片分类测验（WCST）的敏感性和特异性，作为对91名稳定局灶性脑损伤受试者额叶损伤的测量。脑损伤的位置和范围的解剖信息是从MR和CT影像学获得的。额叶与非额叶损伤的受试者在WCST表现上没有显着差异。一些额叶大面积受损的受试者在WCST测试中表现良好，而一些额叶以外受损的受试者则表现不佳。区分额叶和非额叶受试者的最佳截止分数只对62%的受试者进行了正确分类。对WCST表现与额叶各亚区损伤相关的进一步分析也未能揭示任何可靠的关系。这些研究结果表明，在WCST上的表现不能孤立地解释为额叶损伤的指标。
We examined the sensitivity and specificity of the Wisconsin Card Sorting Test (WCST) as a measure of frontal lobe damage in 91 subjects with stable focal brain lesions. Anatomical information about the location and extent of brain damage was obtained from MR and CT transparencies. No significant differences in WCST performance were found between subjects with frontal vs. nonfrontal damage. Some subjects with extensive frontal lobe damage performed well on the WCST, and some subjects with damage outside of the frontal lobes failed. The optimal cutoff scores for discriminating frontal from nonfrontal subjects correctly classified only 62% of the subjects. Further analysis of WCST performances associated with damage to various subregions of the frontal lobes also failed to reveal any reliable relationships. These findings indicate that performance on the WCST cannot be interpreted in isolation as an index of frontal lobe damage.
