Almost every piece of complicated machinery comes with an instruction manual. Without the proper directions it requires much more time and patience to figure out exactly how to use a new car, computer or TV. Using trial and error may be an appealing option to some, but can also lead to miscalculations which can damage new gadgets or, perhaps, even pose a safety risk. I don’t know about you, but I can’t find the the owner’s manual for my brain anywhere. I’m probably not the only one because scientists from around the world are constantly trying to give humans advice about how to optimize mental performance. It’s very difficult to succeed in life if you can’t focus well and retain information adequately. There are certainly environmental and genetic components involved in these mental processes, but that doesn’t mean those with a tendency toward inattention and poor memory need to simply accept those traits. The latest evidence was recently presented by researchers at the University of Wisconsin-Madison . Here’s an overview of what the UW-Madison study entailed: The goal of the experiment was to establish whether attention could be trained in individuals via “mental exercises”. 3 months of Vipassana meditative training and practice was the chosen intervention. Interactive hearing exercises, which included both “standard” and “deviant” sounds, were used to test the participants’ level of distraction. “Moment-to-moment stability of attention” and “reaction time” were the two measures used to quantify focus and mental performance in the group. The authors of the study noted that the meditative practice significantly decreased the occurrence of distractions and helped the study volunteers to better identify the details of the auditory stimuli they were processing. One of the lead researchers, Dr. Richard Davidson, commented that “ongoing fluctuations in attention stability are thought to reflect competitive interactions between task-related and task-unrelated processes, such as mind-wandering. Our work holds that the capacity to stabilize attention is best regarded as a skill that can be trained.” ( 1 ) It’s always reassuring when common sense is supported by controlled scientific evidence. It’s kind of like getting advice about money management from a wise uncle and then having it reaffirmed by a world-renowned economist. A new trial published in the October 2009 issue of the journal Memory and Cognition supports the notion that studying without distractions (music, phone calls, TV, etc.) can improve the way our brains process and retain information. These findings are based on two experiments that were recently conducted at Stanford University . The objective of the research was to assess the effects of “full” or “divided” attention in mental tasks involving both auditory and visual cues. The overall conclusions weren’t unexpected, but they did reveal some valuable clues as to the role that distraction can play in brain function. For instance, the researchers noted that “attention is not only necessary during memory encoding it is also important during memory retrieval to ensure future remembering”. In short, distractions negatively impact the immediate accuracy and formation of memories and the long-term retention of what is learned.

( a ) The November 4th issue of the Journal of Neuroscience starts off in a rather alarming manner. German scientists report that suffering from chronic pain can lead to “damage or loss of brain gray matter”. Fortunately, the news that followed was significantly more optimistic. 32 patients with chronic pain due to osteoarthritis of the hip demonstrated a loss of brain matter in the anterior cingulate cortex (ACC) and several other key areas of the brain including the brainstem. A similar group of pain-free, healthy patients were used as a means of comparison. 10 of the arthritic patients underwent hip replacement surgery. The participants who had the surgical procedure were deemed free of pain 6 weeks
