Bolded are scores that are greater than 1 standard deviation below the normative sample mean (i.e., a T-score < 40); T-scores have a mean of 50 and a standard deviation of 10; %ile, percentile; CVLT-3, California Verbal Learning Test-Third Edition (normed for age, sex, and education); WAIS-IV, Wechsler Adult Intelligence Scale-4th Edition (normed for age, sex, education, and ethnicity); WMS-IV, Weschler Memory Scale-4th Edition (normed for age, sex, education, and ethnicity; BVMT, Brief Visuospatial Memory Test-Revised (normed for age); DKEFS, Delis-Kaplan Executive Function System (normed for age). Boston Naming Test and Grooved Pegboard scores are normed for age, sex, education, and ethnicity; the Rey-Osterrieth Complex Figure Test is normed for age.
