This study examined the performance of two computer-based batteries (CogState and Joggle), and a paper/pencil battery (Neruopsych) as it relates to worse sleep within older black adults (n= 87, females= 68). The computer-based batteries, particularly Joggle, appear to be most sensitive for detecting an association between worse sleep and poor cognitive performance. Results suggest type of cognitive battery administered to older Blacks may influence the ability to detect associations between sleep and cognitive functioning.
