I've already repeatedly told you about my policy regarding discussing personal fight experience on a public open thread. (-_-)

Click on the link. There's thorough evidence from research conducted by Laur as well as others that he references, and a lot of that research was conducted thoroughly too (e.g. as with scientific experiments, they had test groups and control groups).

Proper studies into survival stress reaction and its relation to combat performance dates back to the 1930s;
e.g.
+ Soldiers experienced immense difficulty transmitting Morse code during combat compared to during training. Transmitting Morse is a fine motor skill and research shows that fine motor skills are the first thing that most people lose under combat stress.
+ During the Vietnam War the location of buttons and switches in fighter cockpits were reconfigured according to survival stress reaction research results in order to make them more intuitively accessible during combat

The majority of survival stress reaction research was conducted by the military up until the mid 1960s. Since then there's been a lot more research from non-military researchers as well from sports sciences (seeing how extreme stress reaction relates to athletic performance).
