| Annotation | This Australian study examines the extent to which age-related variance in episodic memory can be explained by taking into account individual differences in cognitive and non-cognitive variables, and their contribution to remembering. Episodic memory was assessed for 3 tasks in a sample of 951 older people aged 70 to 96. Correlations between age and memory accounted for 6-9% of variance. Hierarchical multiple regressions showed a reduction in this age-related variance by up to 94%, after entering gender, depression, health, cognitive status, activities, and speed. General processing speed was the major mediator of age-related variance in memory. Although both the age-related variance and the speed-related variance in memory were significantly reduced by prior entry of other individual differences variables for all 3 tasks, speed remained a significant mediator of remembering, and negligible differences in the residual age-related variance were observed by inclusion of other background variables. |
