Think we all have dif­fer­ent tastes where beauty is con­cerned? Well, cog­ni­tive psy­chol­ogy shows us that an aver­age face (made from sev­eral other faces) is almost always judged as more attrac­tive than its con­stituent faces… Why? It may be for the sim­ple rea­son that an aver­age face is closer to the men­tal idea we have of a pro­to­typ­i­cal face and thus eas­ier for the brain to process.

Want to expe­ri­ence it? Fol­low this link to the the Face Research Lab and cre­ate your own aver­age faces. Enjoy.

Happy stim­u­lat­ing New Year to you!

This is a par­tial list of the lit­er­a­ture we reviewed dur­ing the research phase of our new book, The Sharp­Brains Guide to Brain Fit­ness.  We know many friends of Sharp­Brains are researchers, health­care pro­fes­sion­als, graduate/ Ph.D. stu­dents, who want have direct access to the ref­er­ences (per­haps PubMed should pro­mote itself as a never end­ing source of men­tal stim­u­la­tion?), so here you have this list, orga­nized by rel­e­vant chap­ter. Please note that the list below appears in the book — whose man­u­script we had to close in Jan­u­ary 2009.

Learn­ing can be inci­den­tal. We all mem­o­rize facts with­out pay­ing much atten­tion to these facts or with­out will­ing to mem­o­rize them. How­ever, when one really wants to mem­o­rize a fact, it is cru­cial to pay atten­tion. Many stud­ies have shown that com­pared to full atten­tion con­di­tions, divid­ing atten­tion dur­ing study time leads to poor mem­ory performance.

This exer­cise will help you prac­tice focus­ing your attention.

It may seem easy but make sure you count twice!

Yes­ter­day, Lucy went all the way to Boston. She wanted to buy new shoes. She had to go in many shops before she found the shoes she wanted. She was happy to stop at a restau­rant to have some tea and cook­ies before she took the train back home.

Count the num­ber of “F” in this text:

Fin­ished files are the result of years of sci­en­tific study com­bined with the expe­ri­ence of years.

Last sum­mer, Jean and Har­riet spent their vaca­tion in Michi­gan. They rented a cabin on the lake. The cabin had two bed­rooms and a nice deck. They used to spend a lot of time on the deck, just look­ing at how the light would change on the water. Sev­eral times, they bor­rowed bikes from their neigh­bors and spent a few hours explor­ing the vil­lages not far from their cabin.

Nin­tendo brain-trainer ‘no bet­ter than pen­cil and paper’ (The Times):
“The sur­vey of ten-year-old chil­dren found no evi­dence to sup­port claims in Nintendo’s adver­tis­ing cam­paign, fea­tur­ing Nicole Kid­man, that users can test and reju­ve­nate their grey cells. The Nin­tendo DS is a tech­no­log­i­cal jewel. As a game it’s fine, said Alain Lieury, pro­fes­sor of cog­ni­tive psy­chol­ogy at the Uni­ver­sity of Rennes, Brit­tany, who con­ducted the sur­vey. But it is char­la­tanism to claim that it is a sci­en­tific test.

Com­ments: as we have said before, Nin­tendo Brain Age and Brain Train­ing should be seen as what they are: a game. And the con­struct of one’s hav­ing a  “brain age” makes no sense.

Hav­ing said that, the researcher quoted then offers, out of the blue, a highly inac­cu­rate statement:

“The study tested Nintendo’s claims on 67 ten-year-olds. “That’s the age where you have the best chance of improve­ment,” Pro­fes­sor Lieury said. “If it doesn’t work on chil­dren, it won’t work on adults.”

That asser­tion (that some­thing won’t “work” on adults because it won’t “work” on kids) makes even less sense than hav­ing a “brain age”. The Cog­ni­tive Reserve research shows the need for life­long men­tal stim­u­la­tion — and the real­ity is that kids are more exposed to nov­elty and chal­lenge all the time, whereas older adults may not be. Fur­ther, that claim (some­thing that doesn’t “work” on kids won’t “work” on adults) has already been tested and proven wrong:

In a cou­ple of recent tri­als, dis­cussed here, the same strat­egy game (Rise of Nations, a com­plex chal­lenge for exec­u­tive func­tions), played for the same num­ber of hours (23)  showed quite impres­sive (untrained) cog­ni­tive ben­e­fits in peo­ple over 60 — and no ben­e­fits in peo­ple in their 20s.

How can this be? Well, we often say that our brains need nov­elty, vari­ety and chal­lenge — and it should be obvi­ous that those ingre­di­ents depend on who we are Read the rest of this entry »

If you could, you would. You can, but pre­fer not to know it?

More than any other organ, your brain is up to you. You are what you think, not just what you eat. Here’s some food for thought:

Design your Mind

Set­ting cog­ni­tive and behav­ioral goals raises chal­leng­ing and wor­thy ques­tions: What do you want from your brain? Will you know it when you achieve it?

To attain the brain of our choos­ing, we must under­stand our selves and cur­rent abil­i­ties. Intro­spec­tion and curios­ity are help­ful if they trig­ger and sus­tain the effort to enrich the mind. How­ever, objec­tive infor­ma­tion which leads to informed assess­ment of brain func­tion is often lacking.

Mind your Brain

Hon­esty. Open­ness. Self-awareness.

Irrefutable virtues, but in prac­tice most peo­ple fall short. Few reg­u­larly appraise their brain skills; even so, the abil­ity to accu­rately judge one’s own men­tal per­for­mance is not guar­an­teed. I believe the first step to mind­ing the brain is shed­ding hang-ups while offer­ing and solic­it­ing frank feed­back from fam­ily and close con­fi­dants. In the clin­i­cal set­ting, rou­tine cog­ni­tive screen­ing and “men­tal check ups” are not cur­rently prac­ticed, in part due to time con­straints and lim­ited util­ity of tra­di­tional paper-and-pencil tests. From a pub­lic health per­spec­tive, the U.S. Pre­ven­ta­tive Task Force reviewed Read the rest of this entry »

How many dif­fer­ences can you spot?

You have seen and maybe tried that exer­cise or game in the Sun­day paper many times: find 5 dif­fer­ences between the two images.

You may like it or not. You may think it is only for kids. But it is a GREAT brain exercise!

Let’s see what cog­ni­tive processes and which brain areas are involved in this exercise:

As you have prob­a­bly noticed, a grow­ing num­ber of Expert Con­trib­u­tors are writ­ing in our blog, so that we can col­lec­tively dis­cuss the lat­est research and trends on cog­ni­tive and brain health, and the impli­ca­tions of brain research in gen­eral for our every­day lives. 

If you haven’t done so already, make sure to sub­scribe to our newslet­ter (above) and our RSS feed (on the right).

Below you have the pro­files of some of our Con­trib­u­tors and links to their best arti­cles with us so far. Enjoy!

Do you know where words are stored in your brain…?

In your tem­po­ral lobe! (in green on this pro­file view of the right side of your brain).

As you know your brain has two sides (two hemi­spheres) con­nected by the cor­pus cal­lo­sum. So you have one tem­po­ral lobe on each side of the brain.

If you are right-handed, your lan­guage is stored mostly in your left tem­po­ral lobe. If you are left-handed, you are not so lat­er­al­ized and your lan­guage is stored a bit on both sides of your brain in the tem­po­ral lobes.

Words in the brain are not stored ran­domly. They seemed to be quite orga­nized. Research has shown that words that are often heard together (such as salt and pep­per) or words that share some mean­ing (such as nurse and doc­tor) are con­nected or asso­ci­ated in the brain. Once you hear one, the other is activated.

Here is a brain exer­cise whose aim is to stim­u­late the con­nec­tions or asso­ci­a­tions between words in your tem­po­ral lobe.

In the left col­umn you have a Read the rest of this entry »

Today we have the plea­sure to have Dr. Pas­cale Mich­e­lon, one of our new Expert Con­trib­u­tors, write her first arti­cle here. Enjoy, and please com­ment so we hear your thoughts and engage in a nice conversation.

(Btw, if you notice some sim­i­lar­ity between the col­ors in the fMRI scan below and the look & feel of this site…well, the rea­son is that those orange-grey fMRI col­ors were our inspi­ra­tion! the orange color denotes the most brain activation).

You have prob­a­bly heard about CAT and MRI scans (pro­duced thanks to machines like the one to the top right). So you know that these are tech­niques that doc­tors and sci­en­tists use to look inside the brain.

You have prob­a­bly also heard about brain fit­ness and how impor­tant it is to keep a healthy brain to be pro­tected against age-related and disease-related brain damages.

The ques­tion we ask here is the fol­low­ing: Can we use brain scans to eval­u­ate how fit the brain is? Before we try to answer this ques­tion let’s start with the basics and try to under­stand how brain scans work.

Brain imag­ing, also called neu­roimag­ing, allows one to Read the rest of this entry »
