The following pdf is, i think, part of a presentation from a student led research project from UCLA. The researches were attempting to see if/how different parts of the brain could be linked to MBTI types, by obtaining readings from a group of students interacting with each other and in a number of activites and scenarios.
This is the kind of playful experimenting I would love to be able to do,
Obviously, don't treat this as professional scientific results/process/etc.
Oh..it is 102 powerpoint type pages or so, but each sheet is super simple to read.
