Regulation of Emotion, Sleep Extension, and mTBI

A 1.5-hour nap opportunity compared to a neutral 1.5 hour waking activity (e.g., puzzle completion) prior to task. Participants will either nap or not prior to the emotion regulation task. These two conditions will be counter-balanced within gender and participants will complete them 1 week apart. If they are in the nap condition, they will nap for 1.5 hours with PSG in a dark, soundproofed room with optional fan, white noise, or music. If they are in the no nap condition, they will work on puzzles for 1.5 hours in the same room but with the lights on.
