[SIZE=2]Not likely. True multiple personality disorder is a very rare thing, and the personalities are usually distinct.
I wonder about this. Granted, according to DSM IV-TR you are correct, but I know i have several personality 'tendencies'. Sometimes they seem to be more prevalent in certain brain states, isn't MPD with true distinction just an exaggeration of this? Who knows.
But i would argue that anyone who thinks there is only one single personality fixed and not comprised of different inputs, has never seen or worked with a person with a deviated corpus callosum, or who has 'alien hand syndrome'. kinda freaky.
I'm just suggesting that while maybe even if there are not distinct personalities- functionally, there could be, or even just using the paradigm may prove useful- as long as it is maintained that the analogy is just a paradigm used to break down the many parallel layers of function of our consciousness.
(The wife is attending a pyscho-pharmaceutical conference today, we were up late last night brushing up on the chemical basics of consciousness... I have to admit- it is pretty cool. I'd love to be able to work in the research end of the field.)
