The California Older Adult Stroop Test (COAST) is a Stroop-type test specifically designed and normed on an older adult population. Traditional Stroop-type tests often incorporate blue as a color; older adults may have difficulties distinguishing blue from green accurately due to changes in their vision, which can interfere with accurate results. Blue-green color confusion can be particularly pronounced in persons with dementia. Our test uses red, green and yellow colors and is briefer, suiting older adults in a wide range of clinical and research settings.
The COAST is a timed test and requires use of a stopwatch.
