I'm pondering this question at the moment. As a psychologist interested in creative approaches to therapy, the Jaynesian theory of mind/consciousness is of course thrilling to say the least. I see connections to a lot of areas in psychology.
What about the current rise in interest in both adhd and mindfulness? How are these concepts related? Intuitively I see how adhd mimics a bicameral mind while also fitting nicely with Thom Hartmann's notion of the hunter/gatherer-mind of adhd. "Deficits" in adhd is about the same as those functions needed for conscious executive controling of behaviour, the post-bicameral advantages so to say. Also, the very same "left-side" abilities is what our western culture promotes highly in upbringing and education. Contrasting is the surge in interest in buddhist meditation practice and the promotion of being "here and now" as in mindfulness.
I speculate that adhd is on the table because we've accelerated the development of unicameral culture. Adhd:ers are the ones lagging behind, being too bicameral. At the same time, something is telling us to slow down and to reconsider the prevalent focus on rationality, effiency, planning, organizing and general left-braining (like environmental issues). Consider the Zen notion of No-Mind as a state of bicamerality and meditation as a means to weaken the power of consciousness-ing. In that perspective, my idea of adhd as an ideal platform for meditation makes perfect sense. I allow myself to make a lot of this speculation by linking to This Article
Ooops, I went off topic.
Answer is No, I don't know how to therapy this theory but I'm dying to find out.
What about exploring the avenue of deliteralization
proposed by Hayes et al. in the Acceptance and Commitment Therapy. They have their buddhist connections for sure and the theory behind it, Relational Frame Theory
, fits rather nicely with Jaynes theory.
