Yesterday I drunk quite a few beers.
I stayed to long in the sun.
Hence I got fever of 38.4 C (101.1 F)
My head was filled with cotton balls.
I felt that I couldn't perform any intellectual task.
That was a good moment to test the statement that your IQ is not influenced by how miserable you feel. That is a typical counter intuitive scientific finding.
So I did another 100 exercises at CTS and indeed, my performance was not degraded.
Actually I scored an all time high of 1564!
When I have a good night sleep, I perform badly at CTS during the first few hours after awaking.
Today I tried to see why. That was very difficult, since I felt rather musty.
Pattern recognition worked at its usual lightning speed though. So another part of the process is slowed down.
Usually we divide the solution process in two parts, pattern recognition and calculation.
The speed of pattern recognition isn't influenced by alcohol and fever, nor by sleep.
That leads to the conclusion that alcohol and fever don't have an influence on the speed of calculation either but a good night sleep slows the calculation down (I hope you can follow this).
That's hard to imagine.
Are there other factors at play which I don't know of?
Another conclusion is that the brainprocess that is usually slowed down by alcohol, is not involved in solving chess problems.
So the question rises: "Which brainprocess which is involved in the solution of chessproblems is unaffected by alcohol and fever, but slows down after much sleep?"
