Sleep Deprivation Study

Study Overview

Brief Summary
-----------------
The purpose of this study is to evaluate the measures of brain function, both neurophysiological (event-related potentials (ERPs) and functional (cognitive assessments), in response to sleep deprivation.

Cognitive Change, Sleep Deprivation, Caffeine

Intervention / Treatment
-----------------
* Behavioral: Sleep Deprivation
* Other: Caffeine
* Other: No Caffeine

Primary Purpose: Basic Science
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: 2-group, randomized design
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Sleep Deprivation and Caffeine Intervention<br>Participants randomized into the sleep deprivation group and then randomized into receiving caffeinated coffee the next morning. Participant is blinded to the caffeine intervention. | Behavioral: Sleep Deprivation<br>* Participants will be randomized into either the sleep deprivation group or the control group, who will sleep regularly.<br>Other: Caffeine<br>* On Day 2 morning, after the sleep deprivation or sleeping, participants will be randomized into receiving caffeinated or de-caffeinated coffee, which they will be blinded to.<br>|
| Sham Comparator: Sleep Deprivation and no Caffeine intervention<br>Participants randomized into the sleep deprivation group and then randomized into receiving de-caffeinated coffee the next morning. Participant is blinded to the caffeine intervention. | Behavioral: Sleep Deprivation<br>* Participants will be randomized into either the sleep deprivation group or the control group, who will sleep regularly.<br>Other: No Caffeine<br>* De-caffeinated coffee<br>|
| Active Comparator: Control and Caffeine<br>Participants randomized into the control group, who will sleep regularly, and then randomized into receiving caffeinated coffee the next morning. Participant is blinded to the caffeine intervention. | Other: Caffeine<br>* On Day 2 morning, after the sleep deprivation or sleeping, participants will be randomized into receiving caffeinated or de-caffeinated coffee, which they will be blinded to.<br>|
| Sham Comparator: Control and No Caffeine<br>Participants randomized into the control group, who will sleep regularly, and then randomized into receiving de-caffeinated coffee the next morning.
