Scientific critique of BBC/ Nature Brain Training Experiment

logo-bbcThere has been quite a bit of comment about the Owen et al study in Nature available online on April 20, 2010. A quick synopsis of the study is that the BBC show Bang Goes the Theory worked with the study authors to provide a test of the hypothesis that commercially available brain training programs transfer to general cognitive abilities. The conclusion was that, despite improvements on the trained tasks, “no evidence was found for transfer effects to untrained tasks, even when those tasks were cognitively closely related.”

The experiment

The study was conducted through the show’s web site. Of 52,617 participants who registered, approximately 20% (11,430) completed full participation in the study, which consisted of two benchmarking assessments 6 weeks apart with variants of neuropsychological tests and at least two training sessions. People were randomly assigned to one of three groups that were asked to train for about 10 min a day three times a week for the 6-week period, though they could train either more or less frequently. One of the two experimental groups was a “brain training” group that completed tasks including simple arithmetic, finding missing pieces, matching symbols to a target, ordering rotating numbers by numerical value, updating, and memory for items. Most of the training sessions were 90 sec each; the rotating numbers tasks was 3 min. These activities are similar to those used in “edutainment” programs that can be played online or with a handheld device. The other experimental group was trained on reasoning tasks that involved identifying relative weights of objects based on a visual “seesaw”, selecting the “odd” item in a concept formation type task, a task involving thinking through the effects of one action on current and future states, and three planning tasks including drawing a continuous line around a grid while ascertaining that the line will not hinder later moves, a version of the Tower of Hanoi task, and a tile sliding game. The control group spent time answering questions about obscure facts and organizing them chronologically based on any available online resource. Results indicated that the two experimental groups performed better than the control group on only one outcome test of grammatical reasoning; there were no differences between either experimental group and the controls on the remaining test. The experimental groups had improved on the trained tasks but not on the transfer tasks.

Scientific concerns

Although some news reports suggest that these findings are definitive, there are a number of concerns, many of which have to do with whether the findings have been overgeneralized to all forms of brain training because only a few tests were used. Second, there have been questions raised about the amount of time allocated to training and the issue of testing in the home environment. The study reported Read the rest of this entry »

Brain Research Interview Series

We are working on improving several sections of our website, especially our Resources section. It will look much better in a few days. Our first step has been to re-organize our Neuroscience Interview Series, and below you have how it looks today.

During the last 18 months I have had the fortune to interview over 15 cutting-edge neuroscientists and cognitive psychologists on their research and thoughts. Here are some of our favorite quotes (you can read the full interview notes by clicking on the links):

Brain Health and Fitness Workshops

Today I have an announcement to make. You probably are seeing all the articles about Brain Fitness in the press and wondering, “What is this all about?”, “Can someone help me navigate through all the programs out there?”, “How is Brain Fitness relevant to me in my personal life or at work?”. Well…we are delivering a series of workshops to companies and organizations combining modules -including scientific overview, the industry trends and key players, fun team-building exercises- that can be tailored to each organization’s specific needs. Sessions last from 1 to 6 hours, depending on the group’s composition and agenda and are delivered either in person or via web conference.

We want to be able to reach more organizations, so please let us know of any ideas!

Some recent examples

1. Managing Stress for Peak Performance (we mentioned some notes on an Accenture session)

New and challenging situations – such as taking on new responsibilities– can trigger reactions in our brain and body that limit or even block our decision-making abilities. These reactions may also harm our long-term brain power and health. Although we cannot avoid change and stressful situations, we can learn how to manage our stress levels to ensure peak performance-even in tough moments. The latest neuroscience research proves that stress management is a trainable “mental muscle.” This is true for any high pressure profession, be it trading, sports, or simply modern life.

2. The Science of Brain Health and Brain Fitness (similar to what I will teach at UC Berkeley OLLI)

Neuroscientists have shown how the human brain retains neuroplasticity (the ability to rewire itself) and neurogenesis (the creation of new neurons) during its full lifetime, leading to a new understanding of Read the rest of this entry »
