Procrastinating Again? How to Kick the Habit: Scientific American
http://www.sciam.com/article.cfm?id=procrastinating-again

"Procrastination carries a financial penalty, endangers health, harms relationships and ends careers. “Procrastination undermines well-being on a wide scale,” notes psychologist Timothy A. Pychyl, director of the Procrastination Research Group at Carleton University in Ottawa. Nevertheless, recent work hints at potential upsides to this otherwise bad habit: perpetual foot-draggers seem to benefit emotionally from their trademark tactics, which support the human inclination to avoid the disagreeable." - Scientific American
Almost everyone occasionally procrastinates, but a worrisome 15 to 20 percent of adults routinely put off activities that would be better accomplished right away.
Although biology is partly to blame for foot-dragging, anyone can learn to quit
Procrastination can also stem from anxiety, an offshoot of neuroticism. Procrastinators postpone getting started because of a fear of failure (I am so worried that I will bungle this assignment), the fear of ultimately making a mistake (I need to make sure the outcome will be perfect), and the fear of success (If I do well, people will expect more of me all the time. Therefore, I’ll put the assignment off until the last minute, do it poorly, and people won’t expect so much of me).
One World, Many Minds: Intelligence in the Animal Kingdom: Scientific American

amazing advances in brain studies
Critical of Paul MacLean
“So-called lower animals, such as fish, reptiles and birds, display a startling array of cognitive capabilities. Goldfish, for instance, have shown they can negotiate watery mazes similar to the way rats do in intelligence tests in the lab…”
# Despite cartoons you may have seen showing a straight line of fish emerging on land to become primates and then humans, evolution is not so linear. The brains of other animals are not merely previous stages that led directly to human intelligence. # Instead—as is the case with many traits—complex brains and sophisticated cognition have arisen multiple times in independent lineages of animals during the earth’s evolutionary history. # With this new understanding comes a new appreciation for intelligence in its many forms. So-called lower animals, such as fish, reptiles and birds, display a startling array of cognitive capabilities. Goldfish, for instance, have shown they can negotiate watery mazes similar to the way rats do in intelligence tests in the lab.
