A reasonable hypothesis is that to be creative you have to have this weird dissociation in your frontal lobe, one area turns on and a big area shuts off so that you're not inhibited, so that you're willing to make mistakes, so that you're not constantly shutting down all of these new generative impulses. Charles Limb: Your brain on improvDespite three years of avatar identity hacking, I still don't really understand how Botgirl came into being or continues to exist as a viscerally distinct persona. One way I've tried to understand what's going on with we is by viewing the experience of avatar identity through the context of other phenomena in the same ballpark, like ventriloquism, trance channeling and fictional characters who seem to write themselves.
Whatever is going on with multiple personas through the software of psychology, it's running on the hardware of biology and neurology. So I found the research recounted in this video about what happens in the brain during musical improvisation to be very interesting and possibly related.
I sponsored an informal investigation a few years ago on whether a personality test showed differences between human and avatar identities. It would be interesting to try something similar with a focus on what's happening in the brain. In any case, the presentation captured in this video is intriguing and entertaining on its own merits. Enjoy!
