Normative data on the Korean version of the Boston Naming Test.

The purpose of this study is to introduce the Korean version of the Boston Naming Test (K-BNT) and to present the normative data. The K-BNT contains the same number of test items and uses the identical general administration method as the original Boston Naming Test (BNT). However, most of the items had to be altered due to the linguistic and cultural differences between Korean and English speakers. We administered 60 line-drawing pictures to six hundred normal participants in eight age groups (15-19, 20-24, 25-34, 35-44, 45-54, 55-64, 65-74, and 75 years and older), five educational levels (0, 1-6, 7-9, 10-12, and 13 years and more), and gender. Since the K-BNT scores were not affected by gender and found not to be significantly different among some age groups, we finalized each cell based on four age groups (15-44, 45-54, 55-74, and 75 years and older) and five education levels (0, 1-6, 7-9, 10-12, and 13 years and more). The highest score was achieved by the 15-44 age group with 13 and more years of education (M = 53.93, SD = 3.06), and the lowest by those of 75 years and older with no education (M = 27.42, SD = 8.22).
