However, a series of tests revealed that their cognitive abilities slowed down while in space, “suggesting that processing speed, visual working memory, sustained attention, and risk-taking propensity may be the cognitive domains most susceptible to change in Low Earth Orbit for high-performing, professional astronauts,” the researchers wrote….’ (Victor Tangermann via Futurism)
