The WAIS-III (Wechsler, 1997) was used to measure current level of intellectual abilities (i.e., Full-Scale IQ or FSIQ) for all participants except Case 1, which was estimated based on the Barona formula (Barona, Reynolds, & Chastain, 1984). WAIS-III IQ scores were based on norms for 80+ year olds. VIQ: Verbal Intelligence Quotient, PIQ: Performance Intelligence Quotient;

Indicates significant split between WAIS-III PIQ and VIQ. A difference of 8.63 between scores is considered significant (p<0.05) for those age 80–84 while difference of 9.49 is considered significant for those age 85–89 (Wechsler, 1997). Cases 1, 2 and 5 were included in a previous report (Rogalski et al. 2013).
