The 60-item boston naming test: Norms for cognitively intact adults aged 25 to 88 years

Abstract

Age- and education-stratified norms on the 60-item Boston Naming Test (BNT) are presented for 219 cognitively intact adults aged 25-88 years. The sample size, age range, and education levels of this sample represent an improvement over currently available norms. Eight short forms of the BNT are compared with the 60-item BNT. Frequency of errors for individual BNT items and the distribution of incorrect responses over seven different categories of errors are discussed. Finally, specific probes to overcome difficulties with ambiguous items are suggested.
