Brief Summary
This is a single-center, observational study design. Enrolled participants will be typically, healthy older adults. Participants will complete daily computerized measures, in addition to continuously wearing an Actiwatch device. The study period will last 2 weeks. The objectives of the study are to examine the impact of sleep, pain, and circadian rhythm on practice-related learning in older adults at their preferred versus nonpreferred times of day.

Outcome Measures
Primary Outcomes (1)
Cognition as assessed by computerized neuropsychological testing
Cognitive domains include processing speed, immediate memory, delayed memory, and executive function
Morning and evening completion for 14 days
Study Arms (1)
Typically healthy older adults
Adults 65 years and older with only common late-life medical conditions who will complete a screening that includes a Polysomnograph and assessment that includes Actiwatch.
Interventions
Participants will be screened for sleep disorders other than chronic insomnia with an in-home overnight sleep monitoring. Monitoring will consist of six electroencephalography (EEG) measures, two electrooculography (EOG), and chin electromyography (EMG) according to standard placements. Other channels will include oxygen saturation level, bilateral anterior tibialis EMG, heart rate (EKG), thoracic strain gauge, and a nasal/oral thermistor. A single night of polysomnography will be collected during the 2 weeks of assessment.
This device will be worn on the wrist for 14 continuous days to measure limb movements and ambient light.
