Cognitive processing speed captured on the smartphone during actigraphy-labeled sleep

(A) The median processing speeds—in terms of tapping speed, unlocking time, and locating the app icon—captured for each individual accumulated over the observation period.

(B) The differences in mean processing speed captured during actigraphy-estimated sleep in contrast to the values accumulated in the hour before sleep and after sleep (95% confidence interval). The sizes of the shapes in (B) correspond to the sample size (see the main text for the corresponding degrees of freedom).
