A new study following over 6,000 people shows a clear relationship between reaction time, memory, and cognitive decline. Slower reaction times and poorer memory associated with greater risk of dying in young and old people...
CogLabs Newswire: Slower reaction times and poorer memory are associated with a greater risk of dying in young and old people, a new study shows. The finding in younger subjects is especially surprising, given that prior research linking higher mortality with poorer cognitive function in the elderly was attributed to degeneration of the brain due to aging.
"These results suggest that reaction time is not merely an indicator of age-related physiological deteriorations but rather an indicator of the brain's more basic information processing ability, suggesting that slower and more variable processing skills are a risk factor for mortality in themselves...
