Summary

The goal of this study is to learn whether virtual reality (VR) construction tasks can detect performance changes associated with prior sleep, and to determine the extent to which these changes can be distinguished from interacting repetitively with VR itself.

Detailed description

After passing a physical assessment and psychological screen, up to 12 participants will be enrolled. Ahead of each 8-hour in-laboratory assessment, participants will be asked to participate in a 1-week at-home monitoring period while continuing with their regular sleep/wake schedule. During this at-home assessment participants will be asked to wear an ActiGraph to objectively assess sleep and complete daily sleep diaries and call into a time-stamped voice-mailbox when going to bed and getting out of bed to confirm sleep/wake times. Participants will be asked to refrain from any alcohol, substances, or intense physical activity during each 1-week at home monitoring period. Similarly, participants are asked to refrain from caffeine consumption 5h prior to the in lab. Participants will then participate in two 8-hour sessions in an in-laboratory setting with a 1-week washout period in-between each in-laboratory visit. The two 8-hour visits will be identical in schedule and instrumentation, differing only in whether VR tasks are administered. Order of visits will be randomized. At each visit, participants will arrive to the laboratory \~6h after their habitual waketime (determined from daily call-ins) and be hooked up for ECG and beat-by-beat blood pressure. They will wear an ActiGraph the entire in-laboratory visit. Participants will also be asked to complete the Karolinska Sleepiness Scale (KSS) questionnaire and the modified Positive Affect-Negative Affect Schedule (PANAS) and the Profile of Mood States (POMS) questionnaire. Finally, participants will be asked to complete construction virtual reality tasks using a virtual reality headset during each of the 4 time points at each visit.
