Associations between sleep and cognition. A, Objective sleep (actigraphy composite score) is not associated with performance on the executive function task Trail Making Test (B minus A). B, Subjective sleep (PSQI global score) is positively associated with performance on the trails task. C, Trails task performance is negatively associated with the difference in subjective and objective sleep quality across individuals. PSQI score is inverted on its axis, reflecting that greater scores indicate worse sleep quality. Trail Making Test (B minus A) is also inverted on its axis, reflecting that higher scores indicate worse executive function.
