A cross-sectional study of the effects of age, education, and gender on the Boston Naming Test.

The effects of age, education, and gender on visual confrontation naming using the 60-item Boston Naming Test (BNT) were studied in 1111 "normal" elderly (ages 50-101) and 61 younger adults (ages 20-49). Significantly poorer mean BNT scores and increasing variability (measured in standard deviations) were found with successively older age groups and with lower educational levels even after stratification on the demographic variables. There was a non-significant trend for males to score slightly higher than females. Age declines on the BNT were considerably greater for this cross-sectional data than for the longitudinal data we previously reported.
