What Researchers Did
Researchers confined six individuals in a hyperbaric chamber for 28 days at a low overpressure to repeatedly test their mental performance using four different assessments.
What They Found
Simple mental performance tests, such as sustained attention and visual reaction time, showed a distinct learning effect over the 28 days of isolation. However, more cognitively demanding tasks like short-term memory tests revealed patterns of impairment. While some individual, temporary impairments were noted in the more difficult tests, the overall mental performance of the group appeared to remain largely unchanged throughout the isolation period.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A significant limitation of this study is the very small sample size of only six participants.
