Temporoparietal junction dysfunction and what part it may or may not play in the efficacy of BDSM style dynamicked relationships and LDR versus face to face interactions.
Of course, the psychological and physiological factors do not work in a vacuum but are prey to being effected by sociological factors as well. To wit, whether the person in question is part of a collectivist society or a cult of rugged individualism...
But, the question on my mind is studying the parameters and concatenations of a person being able to view themselves as separate from other... or not.
But, yeah. Some people can read "putting my arms around you to hug you right now" typed out in text and actually feel the arms slipping around them and holding them tightly. While others can read those words and smile and find it "cute." But, it is just words on a screen to them and holds only a minimal "empty" psychological and possibly emotive effect with no physical impact at all.
I'm not even trying to get into which is right and which is wrong. The person who can experience societal interaction without blocks and filters separating self from other. And whether it is the person themselves who is "sick" or the people, the culture, which deems them so. I'm still back on studying the TPJ interplay and messiness that is only just recently beginning to be able to be studied "scientifically" in such as people diagnosed with Autism, Asperbergers, Shizophrenia, Parkinson's, Alzheimer's, amnesiacs...
Fascinating.
