So ~20% of people in this study who got Covid but not Long Covid are still experiencing sever cognitive impairment? That’s not concerning at all! 
Regardless of whether it’s covid or capitalism, this just further increases my suspicions that people around me are losing their damned minds.
The tests here are simple reaction time and “number vigilance tests” btw. Not sure what that second one actually is.
number vigilance tests
Participants view a stream of digits presented in the middle of the screen, one at a time. A new digit is presented ~750ms (for a presentation rate of: 80 words/minute). Whenever the digit is the same as the target digit (which is presented on the right of the screen throughout the task), they have to press the Spacebar. Otherwise they are instructed to not do anything but stay vigilant and wait for the next digit.
So it’s a combination of visual processing, short term memory, and reaction time.
Yeah, but it’s also meant to measure impulsiveness. It’s a type of Go/No Go test. They’re not just measuring how fast you respond when you’re right, but your ability to stop yourself when the answer is wrong.
