Cognitive Performance in WS Subjects (n = 67) versus normal controls

a: Means (circles) and SD (bars) of WAIS-R subtest scores for WS cases. Performance subtests are listed in bold; verbal subtests in plain font. In normal controls (NC), WAIS-R subtest scores are 10±3 (thick gray line). b: Means (circles) and SD (bars) of VIQ, PIQ, and FSIQ scores for WS cases. In normal controls (NC), WAIS-R VIQ, PIQ, and FSIQ scores are 100±15 (thick gray line). c: Principal component analysis of WAIS-R shows subtests contribute differently to intelligence in WS cases versus normal controls. WAIS-R subtest loadings on PC1 in WS cases (x-axis) and normal controls (y-axis). Data used for normal analysis is from Enns and Reddon [27]. Performance subtests are listed in bold; verbal subtests in plain font. The iagonal line is x = y, at which WS and normal loadings are equal.
