| Annotation | An individual-differences approach was used to examine the component processes which predict episodic long-term memory performance. 301 participants aged 20-90 received a 7 hour cognitive battery across 3 days. Key constructs hypothesised to affect long-term memory function were assessed, including multiple measures of working memory and perceptual speed. Latent-construct, structural equation modelling was used to examine the relationship of these measures and age to different types of long-term memory tasks. Speed was a key construct for all three types of memory task, mediating substantial age-related variance. Working memory was a fundamental construct for free and cued recall, but not spatial memory. The data suggest that both speed and working memory are fundamental to explaining age-related changes in cognitive ageing, but that the relative contributions of these constructs vary as a function of the type of memory task. |
