Are any of you aware of any practices for reducing cognitive tunneling (defined below) in a self-defense context?
Cognitive tunneling is an effect that occurs when our brains move from an auto-pilot mode (like when we're walking down the street, just enjoying the day or thinking about work, etc. - Condition White) to a crisis situation (Condition Orange or Red) where decisions are suddenly neceessary. The brain tends to lock in on the single stimulus most dominant (often, right in front of the field of vision at that moment) and ignore all others in decision making. This could lead to a whole range of problems, not the least being focusing on an obvious threat and ignoring two others next to him.
This will seem funny, yet give it a try.
Get online, and read forums, while listening to music and and watching TV.
Type while people are talking and type on a different subject.
Also do things while under stress and or with adrenaline such as on a roller coaster. While in this situation think about things around your and what was around you and ...
Train your body and mind to work on multiple things at once and to pay attention to your surroundings.
Walk into a room and remember what is outside the room and then go back into the other room and and see home much you remembered.
Mileage may vary
