In his new work, the author, a former psychotherapist who has written previously on attention deficit/hyperactivity disorder (Attention Deficit Disorder: A Different Perspective), recommends techniques for raising children diagnosed with this condition. Although many of the specific strategies will be very useful to parents raising ADHD children, too much of the text is devoted to complex genetic and evolutionary theory. According to Hartmann, ADHD is a trait (referred to here as the Edison gene, because the inventor Thomas Edison is believed to have had the trait) rather than a disorder, because it once provided useful skills for functioning in a hunter-gatherer society. The hunter abilities contrasted sharply with the farmer trait, which carried the skills required in farming societies. For example, hunter children have a short attention span, beneficial in a dangerous world where the environment had to be constantly monitored. The innovative but impatient hunter child is usually placed in special ed classes and is looked on as a disciplinary problem; but Hartman believes that ADHD children should be thought of separately. He provides specific guidelines for parents, partly based on the work of Alfred Adler, which encourage mutual respect between parent and child. Hartmann is not an advocate of drug therapy, and he argues for educational reform and alternative schools or home schooling as better learning situations for ADHD children. Hartmann believes that creative outside-the-box thinking, characteristic of those with ADHD, is a real asset to solving many of the world's serious problems. (Oct.)
