Procedures: Participants will be provided with an Actigraph to measure sleep quantity over a one week period. They will be instructed to follow their normal sleep schedules. Participants sleep will averaged across the 7 day period to match them into either a low sleep or high sleep group. Using a single-factor between-group match design subjects will be assigned to one of two sleep conditions: Sleep control (7-8hrs) and sleep deprivation (3-4hrs). Sleep will monitored overnight in a laboratory setting. Subjects will be given 5 positive, 5 negative, and 5 ambiguous written social scenarios. The participant will be instructed to rate how they would feel in the given situation on a 5-pt likert scale assessing the emotions happy, sad, and angry.

Participants in the sleep deprived group will rate all scenarios more negatively (i.e. They will perceive negative scenarios more negatively, perceive ambiguous scenarios more negatively, and perceive positive scenarios less positively). This will confirm our hypothesis. Discussion and Limitations to our Study Statistical Analysis to be used: Nonparametric References Why is this research important?

Hypothesis: Participants in the sleep deprivation group will rate all written scenarios more negatively than people in the control group. Participants: Will be acquired via local universities. The study will be advertised on each university's research site. Participants will be offered monetary compensation of $50 Participants will be informed of possible sleep deprivation Organizational Behavior and Human Decision Processes, 155, 169-180.
