Objective: We compared the relationships among sex, clustering strategy, and recall across different task demands using 16-word California Verbal Learning Test-Second Edition (CVLT-II) 9-word Philadelphia (repeatable) Test (PrVLT). Background: Women generally score higher than men on verbal memory tasks, possibly because women tend to use semantic clustering. This sex difference has been established via word-list learning tests such as CVLT-II. Methods: In a retrospective between-group study, we how 2 separate groups of cognitively healthy older adults performed longer shorter test. The group completing CVLT-II had 36 26 men; PrVLT 27 21 men. Results: Overall, multiple regression analyses revealed that was significantly associated with total both tests’ lists (P<0.001). Sex differences in diminished word list. Conclusions: Semantic uniquely influenced lists. However, serial depending length list (ie, demand). These findings suggest complex nonlinear relationship memory, strategies, demand.
