Participants
Adults (50–89 years of age) who
were healthy and living in the community
were recruited through local
advertisements in community centers,
hospitals, and universities. Consistent
with previous reports of normative
scores,27,28 we targeted a
sample size of 80 participants (10
men and 10 women in each decade
between 50 and 89 years of age).
Assignment to an age cohort was
determined by a participant’s chronological
age at the time of testing.
