The present study aimed to establish norms and evaluate the concurrent validity of TabCAT’s RNT compared to a modified version of the BNT (BNT-15). Participants and Methods: Our study included 177 cognitively and functionally normal older adults from the UCSF Hillblom Brain Aging Network (M_age = 77.9, SD = 7.2, range: 60–97; M_education = 17.7, SD = 2.0; Sex = 59.3% female). The participants identified as non-Hispanic White (82.5%), Asian (8.5%), non-Hispanic African American (3.4%), Hispanic (2.8%), and Other (2.8%). Participants completed the TabCAT RNT and other neuropsychological tests in English. The RNT is a speeded confrontation naming task in which participants are shown successive, black-and-white line drawings and asked to name each object as quickly as possible. The total score is the number of items correctly named in one minute. To minimize the impact of education and vocabulary while maintaining an appropriate level of challenge, items selected were required to be familiar and widely recognized, while exhibiting a range of low to moderate word frequency. Pearson and Spearman correlations were used to determine the association of the RNT and BNT-15 with sample demographics and other neuropsychological tests. Results: RNT scores were normally distributed and inversely correlated with age (r = -0.27, P < .001) but were not related to sex or education (all Ps > .70). Hence, normative data was stratified by age: 60-69 years (n = 24, M_score = 32.4, SD = 7.2), 70-79 years (n = 76, M_score = 31.3, SD = 7.2), 80 and older (n = 77, M_score = 28.6, SD = 7.2). RNT performance was significantly associated with performance on tests of language (confrontation naming, phrase repetition, verbal fluency), and executive function and processing speed (design fluency, trail making, digit span, Stroop); all Ps < .05. RNT performance did not significantly correlate with most measures of episodic memory or visuospatial skills. In contrast, BNT-15 performance correlated with measures of language and episodic memory, but not with measures of executive function or processing speed. Conclusions: Among healthy, highly educated older adults, TabCAT RNT performance declined with age and was unrelated to sex or education. Whereas both RNT and a traditional confrontation naming test were associated with language tests, the RNT was uniquely associated with executive and processing speed measures, consistent with our conceptualization of this test as a measure of speeded lexical access and retrieval. Importantly, the RNT scores were normally distributed with no ceiling effects, which suggests that it may be more useful for the sensitive detection of subtle impairments and change over time.

Objective:

Word finding difficulties are prevalent cognitive complaints among older adults and can signal the presence of neurodegenerative disease pathology. Traditional confrontation naming tests, such as the Boston Naming Test (BNT), lack sensitivity to mild slowing of lexical access and have ceiling effects. In contrast, the Rapid Naming Test (RNT), which is a digital speeded naming test, has a normal distribution. Previously validated for laptop administration (Stiver et. al, 2021), the Rapid Naming Test (RNT) is now available in tablet form on the Tablet-based Cognitive Assessment Tool (TabCAT). The present study aimed to establish norms and evaluate the concurrent validity of TabCAT’s RNT compared to a modified version of the BNT (BNT-15).

Participants and Methods:

Our study included 177 cognitively and functionally normal older adults from the UCSF Hillblom Brain Aging Network (M_age = 77.9, SD = 7.2, range: 60–97; M_education = 17.7, SD = 2.0; Sex = 59.3% female). The participants identified as non-Hispanic White (82.5%), Asian (8.5%), non-Hispanic African American (3.4%), Hispanic (2.8%), and Other (2.8%). Participants completed the TabCAT RNT and other neuropsychological tests in English. The RNT is a speeded confrontation naming task in which participants are shown successive, black-and-white line drawings and asked to name each object as quickly as possible. The total score is the number of items correctly named in one minute. To minimize the impact of education and vocabulary while maintaining an appropriate level of challenge, items selected were required to be familiar and widely recognized, while exhibiting a range of low to moderate word frequency. Pearson and Spearman correlations were used to determine the association of the RNT and BNT-15 with sample demographics and other neuropsychological tests.

Results:

RNT scores were normally distributed and inversely correlated with age (r = -0.27, P < .001) but were not related to sex or education (all Ps > .70). Hence, normative data was stratified by age: 60-69 years (n = 24, M_score = 32.4, SD = 7.2), 70-79 years (n = 76, M_score = 31.3, SD = 7.2), 80 and older (n = 77, M_score = 28.6, SD = 7.2). RNT performance was significantly associated with performance on tests of language (confrontation naming, phrase repetition, verbal fluency), and executive function and processing speed (design fluency, trail making, digit span, Stroop); all Ps < .05. RNT performance did not significantly correlate with most measures of episodic memory or visuospatial skills. In contrast, BNT-15 performance correlated with measures of language and episodic memory, but not with measures of executive function or processing speed.

Conclusions:

Among healthy, highly educated older adults, TabCAT RNT performance declined with age and was unrelated to sex or education. Whereas both RNT and a traditional confrontation naming test were associated with language tests, the RNT was uniquely associated with executive and processing speed measures, consistent with our conceptualization of this test as a measure of speeded lexical access and retrieval. Importantly, the RNT scores were normally distributed with no ceiling effects, which suggests that it may be more useful for the sensitive detection of subtle impairments and change over time.
