| الوصف: | Aim: This study investigates the effects of degree of multilingualism on cognitive functions in adulthood, with focus on episodic memory recall and including measures of verbal fluency as well as global cognition. Design: We studied a large population-based cohort cross-sectionally, and we also assessed changes over time through longitudinal measurements on four time-points over a 15 year period. Participants were drawn from the Betula prospective cohort study in UmeÃ¥, Sweden. The participants included in this study at baseline (n = 894, mean age = 51.44, 59.4% females) were divided according to number of languages into bilinguals (n = 395), trilinguals (n = 284), quadrilinguals (n = 169), and pentalinguals (n = 46). Data and analysis: We analysed performance on tasks of episodic memory recall, verbal fluency (letter and category) and global cognition (Minimental State Examination, MMSE) both cross-sectionally and longitudinally. The control background variables were baseline age, gender, years of education, general fluid ability Gf (Wechsler Block Design Test), and socioeconomic status. We employed a linear mixed modelling approach with entropy balancing weights to assess effects of degree of multilingualism on cognitive functions. Findings and conclusions: Using bilinguals as the reference group, our results indicated that all the other multilingual groups exhibited superior performance on episodic memory recall than bilinguals at baseline. The rate of change over time did not differ for trilinguals and pentalinguals compared to bilinguals. While quadrilinguals declined more over time than bilinguals, they still scored significantly higher than bilinguals at the last test wave. For letter fluency, similarly, all language groups scored higher than bilinguals at baseline, and none of the groups differed from bilinguals in rate of change over time. With regard to category fluency, quadrilinguals scored higher than bilinguals at baseline, but trilinguals and pentalinguals did not ... |
