“Our digital lives make concentration difficult…A group of Cambridge university researchers believes to have developed a “fun” solution to this modern problem. By playing a “brain training” game, called Decoder, players can increase their concentration.

How often do you review and comment on a document while talking on the phone with a colleague about an unrelated matter? Or think about your problems at work while helping your child with his homework? [Read more…] about Brain teaser to test your multi-tasking skills and improve concentration
Concentration–or attention– and memory are two crucial mental skills and are directly related. In fact, many memory complaints have nothing to do with the actual ability to remember things: They come from a failure to focus properly on the task at hand.
For example, when you don’t remember where you parked your car [Read more…] about Brain fitness tips to improve concentration and memory
Excellent Scientific American cover story:
“Will a pill at breakfast improve concentration and memory—and will it do so without long-term detriment to your health?”
Their answer, in short: not really, not anytime soon.
I couldn’t agree more. Let’s pay real attention to non-invasive options to augment cognition, from exercise to cognitive training and meditation.
For more context, you may enjoy my recent article Preparing Society for the Cognitive Age, published in Frontiers in Neuroscience.
Have you already read The SharpBrains Guide to Brain Fitness?
1. Pick the only part of your body that does not contain fat:
Answer: d) Fats are also present in the brain: in neurons’ membranes to keep them flexible. These fats are the omega 3 and omega 6 fatty acids molecules. (Page 32 of the book)
2. Pick the only food product that doesn’t contain Omega‑3 fatty acids
d. Jelly Beans
Answer: d) Fatty acids can be found in cold-water fish (such as mackerel, herring, salmon, and tuna), kiwi, and walnuts. (Page 33)
3. Pick the only food product that doesn’t contain antioxidants
a. Olive oil
Answer: b) Antioxidants can be found in vegetable oils, nuts, green leafy vegetables (e.g., spinach), citrus fruit, and berries. (Page 33)
4. Chronic Stress cannot:
a. Prevent you from being creative
b. Kill brain cells
c. Prevent you from sleeping
d. Kill liver cells
Answer: d) Prolonged exposure to adrenal steroid hormones like cortisol, which is released into the blood stream when we are stressed, can lead to cell death and block the formation of new neurons. (Page 35)
5. What type of physical exercise is the best for your brain health?
a. Weight lifting
b. Aerobic exercises
c. Flexibility exercises [Read more…] about Brain Quiz: Do You Have a Brain?
The growing field of cognitive training (one of the tools for brain fitness) can appear very confusing as the media keeps reporting contradictory claims. These claims are often based on press releases, without a deeper evaluation of the scientific evidence.
Let’s take a couple of recent examples, in successive days:
“It doesn’t work!” type of headline:
Reuters (Feb. 10, 2009) Formal brain exercise won’t help healthy seniors: research”
Healthy older people shouldn’t bother spending money on computer games and websites promising to ward off mental decline, the author of a review of scientific evidence for the benefits of these “brain exercise” programs says.
It works! type of headline:
ScienceDaily (Feb. 11, 2009) “Computer Exercises Improve Memory And Attention, Study Suggests”
According to the researchers, participants who used the Brain Fitness Program also scored as well as those ten years younger, on average, on memory and attention tests for which they did not train.
So, does structured brain exercise / cognitive training work or not?
The problem may in fact reside in asking this very question in the first place, as Alvaro pointed out a while ago in his article Alzheimer’s Disease: too serious to play with headlines.
We need a more nuanced set of questions.
1. Cognition is made of several different abilities (working memory, attention, executive functions such as decision-making, etc)
2. Available training programs do not all train the same abilities
3. Users of training programs do not all have the same needs or goals
4. We need to differentiate between enhancing cognitive functions and delaying the onset of cognitive deficits such as Alzheimer’s.
Let’s illustrate these points, by [Read more…] about Does cognitive training work? (For Whom? For What?)
