Objective: Although it is well-known that lifestyle factors can influence cognitive health in aging, few studies have explored the relationship between everyday activities and cognition in older adults (Ferreira et al., 2015). The number of perseverative errors committed on the Wisconsin Card Sorting Test (WCST) is particularly sensitive to the effects of aging on cognition (Rhodes, 2004). Aging has also been associated with progressive declines in performance on the WCST with respect to number of errors and perseverative responses (Axelrod & Henry, 1992). The authors investigated the relationship between regular use of Sudoku and/or crossword puzzles and performance on the WCST among healthy older adults. Method: As part of a larger study, healthy older adults, ages 57-86 (M = 71), who do (n = 13) and do not (n = 21) regularly use Sudoku/crossword puzzles were given the WCST and a questionnaire on leisure activities. A Kruskal-Wallis H test was...
