Study Arms:
- LabyrinthVR Trackers (Type: EXPERIMENTAL): Multi-session cognitive intervention with head-mounted display virtual reality computer game that presents an adaptive spatial wayfinding challenge. Game movement via participant ambulation wearing leg-position trackers.
- LabyrinthVR Scoot (Type: EXPERIMENTAL): Multi-session cognitive intervention with head-mounted display virtual reality computer game that presents an adaptive spatial wayfinding challenge. Game movement via teleporting technique.
- Placebo Controls (Type: PLACEBO_COMPARATOR): Multi-session cognitive intervention with handheld tablet or wireless virtual reality headset presentation of commercially available, narrative computer games.
- Coherence (Type: ACTIVE_COMPARATOR): Multi-session cognitive intervention with head-mounted display virtual reality computer game that presents an adaptive rhythm training game.
- Labyrinth Tablet (Type: EXPERIMENTAL): Multi-session cognitive intervention with tablet computer, displaying 2.5D version of Labyrinth game in an adaptive spatial wayfinding challenge. Game movement via on-screen control buttons.
- Labyrinth VR wireless (Type: EXPERIMENTAL): Multi-session cognitive intervention with head-mounted display virtual reality computer game using wireless, narrower filed technology to presents an adaptive spatial wayfinding challenge. Game movement via teleporting technique.

Based on this trial design, predict the completion outcome and termination type (if applicable).
