California Verbal Learning Test: normative data for the elderly.

Overlapping age tables were developed, separately for males and females, to provide additional normative information for the California Verbal Learning Test (CVLT) and extend the normative data to persons older than 80 years of age. Participants were 92 males and 120 females with means for age and education of 70.58 years (SD = 6.98) and 14.92 years (SD = 2.56), respectively. Normative information was also provided for additional measures of retention rate and proportion of perseverations and intrusions. The clinical utility of these norms strongly depends on how closely a person matches the demographic characteristics of the normative group.
