| Annotation | Sensory disability, grip strength, and speed of processing have been established as associates of cognitive performance in cross-sectional studies. However, it is not known whether changes in these predictor variables are associated with changes in cognitive functioning. This Australian study examined the relationship between initial level of three predictor variables - speed of processing, sensory disability and grip strength - and changes in memory and crystallized intelligence (CIQ). It also examined the relationships between change in grip strength, cognitive speed and sensory disability and changes in memory and CIQ; and investigated these relationships with the effects of age and sex statistically removed. Results showed that initial levels of reaction time or grip strength did not predict rate of change on memory tasks. Changes in grip strength, speed and memory correlated moderately, suggesting that these variables have some tendency to move together over time. Sensory disability correlated with age, but not with change in speed, grip, memory or CIQ. These relationships held across the age range studied, after adjustment for age and sex. (KJ/RH). |
