OF TWO MINDS: THE REVOLUTIONARY SCIENCE OF DUAL-BRAIN PSYCHOLOGY

Ever since Freud, we've known that we share our mental space with another mind, one that may prove quite a hindrance. It can be like a bad roommate we can't evict, leaving dirty dishes in the sink and playing the stereo too loud, and all we can do is try to adjust its excesses with a few carefully worded notes. Dr. Fredric Schiffer believes that he has located the culprit and learned how to talk to it, and his clinical success with problems like cocaine addiction, depression, and posttraumatic stress disorder suggest that he's on to something. Of Two Minds is his report from the front.

A psychiatrist affiliated with Harvard Medical School, Schiffer has studied split-brain research and devised his own experiments to show that stress and anxiety are often felt more strongly in one hemisphere than the other. No simple "left brain good, right brain bad" dichotomy, it seems that those who have been affected by emotional trauma lateralize the effects, perhaps in an effort to maintain more-or-less-normal functioning. One hemisphere or the other gets stuck in the past, says Schiffer, and acts out through the patient's symptoms. His goal is integration of these two minds into a kind of team by using clever manipulation of sensory stimuli and other tools of cognitive science.

Of Two Minds is unusual in its acceptance of both scientific and emotional validity. Alternating reviews of the data with often heart-wrenching transcripts of therapy sessions, it offers a two-pronged assault on what seems to be a dual-natured problem. While it might not solve your "roommate problem" overnight, it may start you on the road to reconciliation. --Rob Lightner
