Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Light
one hour of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during hour immediately prior to desired waketime
Flashes
one hour of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during the hour immediately prior to desired waketime
Fake light
during hour immediately prior to desired waketime, subjects will receive one light flash (insufficient to cause phase shift)
Flashes
one hour of a sequence of light flashes (4000 lux, 3 msec, every 30 seconds); occurs during the hour immediately prior to desired waketime
