A couple of recent studies have reinforced the lifelong potential for brain plasticity (the ability of the brain to rewire itself through experience) and the importance of physical exercise for cognitive vitality. One study focused on 1) adults over 50 with mild cognitive impairment, the other one on 2) stroke survivors.

1)  Memory problems: Adults 50-years-old and over with mild cognitive impairment (an advanced form of memory problems, but pre-dementia) were asked to exercise for three 50-minute sessions per week for 24 weeks (a total of 60 hours). Results: there were small, but measurable, cognitive benefits even 18 months after Read the rest of this entry »

Reader Theresa Cerulli just forwarded this Letter to the Editor that she had sent to the New York Times and went unpublished. The letter addresses the OpEd mentioned here (pitching physical vs. mental exercise), and refers to the Cogmed working memory training program, whose results have been studied in multiple papers published in top medical and scientific journals.

Dear Editor:

I applaud Sandra Aamodt and Sam Wang for throwing some cold water on the current brain fitness craze in their recent New York Times Magazine Opinion Editorial “Exercise on the Brain.” They are correct in labeling the host of “mental fitness” products that target aging baby boomers as “inspired by science — not to be confused with actually proven by science.” For the last 30 years, terms like “brain plasticity” have been widely and casually used, creating hype that risks drowning out the real breakthroughs that brain researchers are making in this area.

However, I would like to distinguish the “mental fitness” trend that Aamodt and Wang rightly criticize from actual researched-based cognitive training such as the Cogmed program developed in Sweden. Unlike “mental fitness” programs, cognitive training programs focus very narrowly on specific cognitive functions that research has shown to be plastic. This is in stark contrast to compiling a smattering of exercises or activities that are generally thought to be Read the rest of this entry »

Brett N. Steenbarger , Ph.D. Associate Professor of Psychiatry and Behavioral Sciences at SUNY Upstate Medical University, active trader for over 30 years, former Director of Trader Development for Kingstree Trading, LLC, author of The Psychology of Trading and the new Enhancing Trader Performance, and of the blog TraderFeed: Exploiting the edge from historical market patterns, is writing a great collection of best practices for traders (many of which are very relevant for all high-pressure occupations).

He wrote a great article a few weeks ago on the value of biofeedback in achieving self control, and now deepens the discussion with this best practice for traders.

Both articles are a fun read-here go some quotes from the most recent one

• “This best practice describes biofeedback as a tool for performance enhancement among traders. It emphasizes that the role of biofeedback is to keep us in touch with our (implicit) knowledge, not to eliminate emotion from the decision-making process.”

• “we want to control the level of cognitive and physical arousal so that we retain access to expertise that is already present. Biofeedback is a powerful tool for achieving such cognitive and physical control.”
• “Through structured practice, people can learn to systematically improve their ability to enter and remain in states of calm focus. Such ability is important to trading (and many other performance activities), not because it eliminates emotion, but because it preserves our access to the somatic markers that represent our market feel. The heart rate variability feedback is particularly user friendly, because it is computer based and can track progress both in practice sessions and in real time performance.”
• “Using the Freeze-Framer program, audible signals tell the user when he or she is experiencing high, medium, or low “coherence”, which is a measure of emotional regulation. On-screen games require the user to keep a floating balloon in the air, for instance, based upon sustained medium and high readings. I recently had an interesting experience during one feedback session: I sustained a high level of the balloon, but then clicked a wrong button on the screen and erased my data accidentally! After that frustration, it was *much* harder for me to keep the balloon in the air. It was a nice illustration of the impact of frustration even several minutes after an event.”
