The Virtual Kitchen Challenge: Relations between everyday function and cognition in older adults with healthy or impaired cognition

VKC measures of task accomplishment and time off-screen differed between healthy and impaired groups and may be sensitive to the cognitive aspects of everyday function at higher levels of impairment. Group differences in B/L completion time were eliminated after controlling for BT completion time, suggesting that VKC completion time may reflect motor or touchscreen proficiency. Future research should investigate VKC associations with computer proficiency and preclinical biomarkers, as well as VKC predictive validity for cognitive decline.
