We conducted multivariate random-effect analyses on longitudinal data from 238 adults, ranging in age from 30 to 94, who were tested on five lexical tests over a period of 20 years to examine (a) the relations between lemma and lexeme retrieval as manifested in different tests of lexical retrieval and (b) changes in lexical processing during older adulthood. This study documents differing profiles of age-related decline in lexical retrieval determined by task demand, gender, education, and underlying cognitive skills. The tasks that required retrieval of unique lexical items (Boston Naming Test and Action Naming Test) yielded significant age-related decline that became more rapid in older age, distinguishing them from tasks that allowed for the retrieval of various lexical items. Findings support a cascaded progression of lemma and lexeme retrieval during word production.

This study tests the hypothesis that retrieval of object and action names declines at different rates with age. Uncued and cued performance on the Boston Naming Test (BNT) and the Action Naming Test (ANT) were examined for 171 individuals from 50 to 88 years old. To control for differences in item difficulty, a subset of items from each of the two tests was selected for which uncued performance was equivalent in individuals in their 50s. With this matched set of items, differences in action and object naming were tested in the 60s and 70+ age groups. Although age-related decline in name retrieval was observed for both the BNT and the ANT subsets, no differences between object and action retrieval were found. Our results, thus, do not confirm previous studies reporting that object names and action names are differentially retrieved with aging. We discuss these new findings in relation to evidence of dissociations in object and action naming in brain-damaged individuals. (JINS, 2002, 8, 764–770.)

Abstract Objective The Boston Naming Test (BNT) is a lexical-retrieval task. It has been documented that those with a history of traumatic brain injury (TBI) have reduced performance on the BNT. Bilingualism is also known to impact BNT performances. We examined the relationship of TBI and bilingualism/monolingualism on BNT performances. Method The sample (N = 95) consisted of 36 healthy controls (19 bilingual; 17 monolingual), 32 acute TBI participants (12 bilingual; 20 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. All participants passed performance validity testing. A 3X2 ANOVA was conducted to determine the effect of TBI and bilingualism/monolingualism on BNT performance. Results A main effect was found for group (i.e., control, 6 month TBI, and 12 month TBI), p < .001, ηp² = .21. Pairwise comparisons revealed that acute TBI participants performed worse than the control and chronic TBI groups. A main effect for bilingualism/ monolingualism was found, p < .001, ηp² = .14; monolinguals performed better on the BNT. No interactions were found between TBI and bilingualism/monolingualism. Conclusions BNT performance improves overtime in TBI and the pattern of improvement post-TBI is not statistically different between bilingual/monolingual groups. Relative to monolinguals, bilingual participants demonstrated worse BNT performance.

Background: Age-related hearing loss (HL) has been associated with dementia, though the neurocognitive profile of individuals with HL is poorly understood. Objective: To characterize the neurocognitive profile of HL. Methods: N = 8,529 participants from the National Alzheimer’s Coordinating Center ≥60 years and free of cognitive impairment who were characterized as Untreated-, Treated-, or No HL. Outcomes included executive function (Trail Making Test [TMT] Part B), episodic memory (Immediate/Delayed Recall), language fluency (Vegetables, Boston Naming Test), and conversion to dementia. Regression models were fit to examine associations between HL and neurocognitive performance at baseline. Cox proportional hazards models examined the links between HL, neurocognitive scores, and development of dementia over follow-up. Results: At baseline, those with Untreated HL (versus No HL) had worse neurocognitive performance per standardized difference on executive function (TMT Part B [mean difference = 0.05 (95% CI 0.00, 0.10)]) and language fluency (Vegetables [mean difference = –0.07 (95% CI –0.14, –0.01)], Boston Naming Test [mean difference = –0.07 (95% CI –0.13, –0.01)]). No differences in these neurocognitive performance scores were demonstrated between Treated HL and No HL groups other than MMSE [mean difference = –0.06 (95% CI –0.12, 0.00)]. Through follow-up, executive dysfunction differed by hearing group (χ 2(2) = 46.08, p <  0.0001) and was present among 39.12% in No HL, 44.85% in Untreated HL, and 49.40% in Treated HL. Worse performance across all cognitive domains predicted incident dementia. Conclusion: The observed association between Untreated HL and lower cognitive ability that improved when hearing aids were worn may reflect an inability to hear the test instructions. Future studies using cognitive assessments validated for use in HL are needed to evaluate the neuropsychological profile of HL and identify individuals at risk for dementia.

Language processing in older adulthood is a model of balance between preservation and decline. Despite widespread changes to physiological mechanisms supporting perception and cognition, older adults’ language abilities are frequently well preserved. At the same time, the neural systems engaged to achieve this high level of success change, and individual differences in neural organization appear to differentiate between more and less successful performers. This chapter reviews anatomical and cognitive changes that occur in aging and popular frameworks for age-related changes in brain function, followed by an examination of how these principles play out in the context of language comprehension and production.

This study compared prorated Boston Naming Test (BNT-P; omitting the noose item) and standard administration (BNT-S) scores in physical medicine and rehabilitation patients ( N = 480). The sample was 34% female and 91% White with average age and education of 46 ( SD = 15) and 14 ( SD = 3) years, respectively. BNT-P was calculated by summing correct responses excluding item 48 and estimating the 60-item score with cross multiplication and division. BNT-P and BNT-S scores were compared via concordance correlation (CC) coefficients; reflected and log transformed data were examined with equivalence tests. BNT-P and BNT-S scores showed almost perfect agreement (CC = .99). Transformed scores demonstrated equivalence (±1.1 points). Raw and scaled score differences were 0 in 88% and 96% of cases, respectively. Race and ethnicity accounted for item 48 outcomes while controlling for age and education. Findings support the utility of prorated BNT scores in rehabilitation patients.
