Measure
Primary Insomnia (PI)
PI sufferers enrolled will meet Research Diagnostic Criteria for insomnia disorder, score \> 14 on the Insomnia Severity Index, report insomnia for \> 3 months, have sleep difficulties \> 3 nights per week, score \< 3 on the Epworth Sleepiness Scale (ESS), score \> 40 on the Hyperarousal Scale10 and report an inability to nap in the daytime. Multiple Sleep Latency Test (MSLT): The daytime protocol will include a 4-trial Multiple Sleep Latency Test (MSLT) along with 4-trials of a computer -administered battery of reaction time tasks. The assessment protocol will start two to three hours after participants' respective morning rising times and will begin with a battery of the neuro-cognitive testing followed by an MSLT nap. Per standard MSLT procedures, the daytime testing will be scheduled so the four performance testing and sleepiness assessment trials occur two hours apart. All daytime testing will be conducted under the supervision of trained laboratory technologists.
Normal Sleepers (NS)
The normal sleepers enrolled will report general satisfaction with sleep and no sleep/wake complaints, score \< 10 on the ESS, score \< 35 on the Hyperarousal Scale10, and deny a practice of routine daytime napping. Multiple Sleep Latency Test (MSLT): The daytime protocol will include a 4-trial Multiple Sleep Latency Test (MSLT) along with 4-trials of a computer -administered battery of reaction time tasks. The assessment protocol will start two to three hours after participants' respective morning rising times and will begin with a battery of the neuro-cognitive testing followed by an MSLT nap.
