Forty-nine young adults (M age = 22 years) and 30 elderly adults (M age = 69 years) rated the 60 pictorial stimuli from the Boston Naming Test (BNT) on familiarity, providing the first such normative data for these stimuli along this dimension. Participants also made speeded lexical decisions about the word item representations of each BNT picture. B NT word frequency values were also examined in relation to BNT familiarity and speeded lexical decision performance. For both young and elderly adults, lexical decision reaction times to the word representations of BNT stimuli were negatively related to word frequency and familiarity of the BNT pictures. These patterns suggest that increases in word frequency and picture familiarity facilitate (i. e., speed up) the processing of BNT word representations. Furthermore, speed of processing appears to be a relevant dimension of BNT performance, at least when young and elderly adults free from clinical aphasia are involved.
