Is Your Brain Being Wired By Tech­nol­o­gy? (Cen­ter for Brain­Health at UT-Dallas):

“…Research shows we are exposed to three times more infor­ma­tion today as com­pared to four decades ago. This infor­ma­tion over­load leads to more mul­ti­task­ing and forces us to push our brain to do things it was not built to do.

Study: Working memory training can improve fluid intelligence

by

Very inter­est­ing new study on com­put­er­ized cog­ni­tive train­ing (or brain train­ing), well sum­ma­rized in LA Times arti­cle Mem­o­ry train­ing improves intel­li­gence in some chil­dren, report says. Quote:

The train­ing pro­gram used by Jaeg­gi and co-work­ers focused on ramp­ing up work­ing mem­o­ry: the abil­i­ty to hold in mind a hand­ful of infor­ma­tion bits briefly, and to update them as need­ed. Cog­ni­tive sci­en­tists con­sid­er work­ing mem­o­ry a key com­po­nent of intel­li­gence. But they have [Read more…] about Study: Work­ing mem­o­ry train­ing can improve flu­id intelligence

Brain Fitness Update: Best of 2008

by

Dear read­er and mem­ber of Sharp­Brains’ community,
We want to thank you for your atten­tion and sup­port in 2008, and wish you a Hap­py, brain fitness and health newsletterPros­per­ous, Healthy and Pos­i­tive 2009!

Below you have the Decem­ber edi­tion of our month­ly newslet­ter. Enjoy:

Best of 2008 

Announc­ing the Sharp­Brains Most Impor­tant Book of 2008: Neu­ro­sci­en­tist Torkel Kling­berg has writ­ten a very stim­u­lat­ing and acces­si­ble book on a cru­cial top­ic for our Infor­ma­tion Age: The Over­flow­ing Brain: Infor­ma­tion Over­load and the Lim­its of Work­ing Mem­o­ry. We have named it The Sharp­Brains Most Impor­tant Book of 2008, and asked Dr. Kling­berg to write a brief arti­cle to intro­duce his research and book to you. Enjoy it here.

Top 30 Brain Fit­ness Arti­cles of 2008: We have com­piled Sharp­Brains’ 30 most pop­u­lar arti­cles, writ­ten by thir­teen Expert Con­trib­u­tors and staff mem­bers for you. Have you read them all?

Novem­ber-Decem­ber News: No month goes by with­out sig­nif­i­cant news in the field of cog­ni­tive fit­ness. Sum­ma­rized here are 10 recent devel­op­ments wor­thy of atten­tion, includ­ing an upcom­ing brain train­ing prod­uct for ice hock­ey play­ers, my lec­ture at New York Pub­lic Library, and more.

Inter­views: Videogames, Meditation

Are videogames good for your brain?: A land­mark study by Dr. Arthur Kramer and col­leagues has shown that play­ing a strat­e­gy videogame can bring a vari­ety of sig­nif­i­cant men­tal ben­e­fits to old­er brains. Anoth­er recent study, also by Kramer and col­leagues, does not show sim­i­lar ben­e­fits to younger brains (despite play­ing the same game). How can this be? Dr. Kramer, who has kind­ly agreed to serve on Sharp­Brains’ Sci­en­tif­ic Advi­so­ry Board, elaborates.

Med­i­ta­tion on the Brain: Dr. Andrew New­berg pro­vides an excel­lent overview of the brain ben­e­fits of prac­tices such as med­i­ta­tion. He rec­om­mends, “look for some­thing sim­ple, easy to try first, ensur­ing the prac­tice is com­pat­i­ble with one’s beliefs and goals. You need to match prac­tice with need: under­stand the spe­cif­ic goals you have in mind, your sched­ule and lifestyle, and find some­thing practical.” 

The Need for Objec­tive Assessments 

Cog­ni­tive screen­ings and Alzheimer’s Dis­ease: The Alzheimer’s Foun­da­tion of Amer­i­ca just released a thought­ful report advo­cat­ing for wide­spread cog­ni­tive screen­ings after the age of 65 (55 giv­en the right con­di­tions). Sharp­Brains read­ers, probed by Dr. Joshua Stein­er­man, seem to agree.

Quan­ti­ta­tive EEG for ADHD diag­no­sis: Dr. David Rabin­er reports on the find­ings from a recent study that doc­u­ments the util­i­ty of Quan­ti­ta­tive EEG as an objec­tive test to assist in the diag­no­sis of ADHD. If this pro­ce­dure were to become more wide­ly used, he sug­gests, the num­ber of chil­dren and ado­les­cents who are inap­pro­pri­ate­ly diag­nosed and treat­ed for the dis­or­der would dimin­ish substantially.

Shall we ques­tion the brand new book of human trou­bles?: The fights over the new ver­sion of the psy­chi­atric diag­nos­tic man­u­al, the DSM‑V, are start­ing to come to light. Dr. Vaugh­an Bell won­ders why the pub­lic debate avoids the key ques­tion of whether diag­no­sis itself is use­ful for men­tal health and why psy­cho­met­rics are sim­ply ignored.

Resources for Life­long Learning

Edu­ca­tion builds Cog­ni­tive Reserve for Alzheimers Dis­ease Pro­tec­tion: Dr. Pas­cale Mich­e­lon reviews a recent study that sup­ports the Cog­ni­tive Reserve hypoth­e­sis — men­tal­ly stim­u­lat­ing expe­ri­ences through­out life, such as for­mal edu­ca­tion, help build a reserve in our brains that con­tributes to a low­er prob­a­bil­i­ty of devel­op­ing Alzheimer’s symptoms.

5 Tips on Life­long Learn­ing & the Adult Brain: Lau­rie Bar­tels asks us to please please 1) chal­lenge our­selves with new learn­ing, 2) remem­ber that neu­ro­plas­tic­i­ty and neu­ro­ge­n­e­sis are hall­marks of our brains, 3) check for mis-learn­ing on an ongo­ing basis, 4) more visu­als, less text, 5) move it, move it — start today!

Neu­ro­science Core Con­cepts: We all have heard “Use It or Lose It”. Now, what is “It”? The Soci­ety for Neu­ro­science (SfN) has just released a user-friend­ly pub­li­ca­tion titled Neu­ro­science Core Con­cepts, aimed at help­ing edu­ca­tors and the gen­er­al pub­lic learn more about the brain.

Torkel Klingberg helps with Overflowing Brain & Information Overload

by

Karolin­s­ka Insti­tute’s Dr. Torkel Kling­berg has just released in the US his excel­lent book The Over­flow­ing Brain: Infor­ma­tion Over­load and the Lim­its of Work­ing Mem­o­ry the Overflowing Brain by Torkel Klingsberg

The title was first released in Swe­den with great suc­cess, and our co-founder Dr. Elkhonon Gold­berg gave a Fore­word to the new US edition.

Dr. Kling­berg will be writ­ing an essay for Sharp­Brains read­ers soon, so we can dis­cuss the impor­tance of this top­ic and his work in depth. Let me now link to two thought-pro­vok­ing reviews of the book:

Atten­tion Must Be Paid (Inside High­er Ed)

- “The weak link in the infor­ma­tion age seems to be our human hard-wiring. So one gath­ers from The Over­flow­ing Brain: Infor­ma­tion Over­load and the Lim­its of Work­ing Mem­o­ry (Oxford Uni­ver­si­ty Press) by Torkel Kling­berg, who is a pro­fes­sor of devel­op­men­tal cog­ni­tive neu­ro­science at the Stock­holm Brain Insti­tute. A review of recent research on how atten­tion and mem­o­ry actu­al­ly func­tion with­in our gray mat­ter, it is a work of sci­en­tif­ic pop­u­lar­iza­tion rather than a hand­book on how to min­i­mize the cog­ni­tive drain of distraction.”

- “To sim­pli­fy Kling­berg’s already pared-down analy­sis, we can dis­tin­guish between two kinds of atten­tion. One is con­trolled atten­tion: the direct­ed effort to apply ones con­cen­tra­tion to a par­tic­u­lar task. The oth­er is stim­u­lus-dri­ven atten­tion, which is an invol­un­tary response to some­thing hap­pen­ing in the envi­ron­ment. (You can tune out the con­ver­sa­tions going on around you in a restau­rant. But if a wait­er drops a tray full of dish­es, it is going to impose itself on your awareness.)”

Information Overload? Seven Learning and Productivity Tips

by

We often talk in this blog about how to expand fun­da­men­tal abil­i­ties or cog­ni­tive func­tions, like atten­tion, or mem­o­ry, or emo­tion­al self-reg­u­la­tion. Think of them as mus­cles one can train. Now, it is also impor­tant to think of ways one can use our exist­ing mus­cles more efficiently.

Let’s talk about how to man­age bet­ter the over­whelm­ing amount of infor­ma­tion avail­able these days.

Hun­dreds of thou­sands of new books, ana­lyst reports, sci­en­tif­ic papers pub­lished every year. Mil­lions of web­sites at our googletips. The flow of data, infor­ma­tion and knowl­edge is grow­ing expo­nen­tial­ly, stretch­ing the capac­i­ty of our not-so-evolved brains. We can com­plain all day that we can­not process ALL this flow. Now, let me ask, should we even try?

Prob­a­bly not. Why engage in a los­ing propo­si­tion. Instead, let me offer a few strate­gies that can help man­age this flow of infor­ma­tion better. 

1. Pri­or­i­tize: strate­gic con­sult­ing firms such as McK­in­sey and BCG train their staff in the so-called 80/20 rule: 80% of effects are caused by the top 20% of caus­es. In a com­pa­ny, 80% sales may come from 20% of the accounts. Impli­ca­tion: focus on that top 20%; don’t spend too much time on the 80% that only account for 20%.

2. Lever­age a sci­en­tif­ic mind­set. Sci­en­tists shift through tons of data in effi­cient, goal-ori­ent­ed ways. How do they do it? By first stat­ing a hypoth­e­sis and then look­ing for data. For exam­ple, an untrained per­son could spend weeks “boil­ing the ocean”, try­ing to read as much as pos­si­ble, in a very frag­men­tary way, about how phys­i­cal exer­cise affects our brain. A trained sci­en­tist would first define clear hypothe­ses and pre­lim­i­nary assump­tions, such as “Phys­i­cal exer­cise can enhance the brain’s abil­i­ty to gen­er­ate new neu­rons” or “Those new neu­rons appear in the hip­pocam­pus”, and then look specif­i­cal­ly for data that cor­rob­o­rates or refutes those sen­tences, enabling him or her to refine the hypothe­ses fur­ther, based on accu­mu­lat­ed knowl­edge, in a vir­tu­ous learn­ing cycle. 

3. Beat your ene­mies-like exces­sive TV watch­ing. Watch­ing TV five hours a day has an effect on your brain: it trains one’s brain to become a visu­al, usu­al­ly unre­flec­tive, pas­sive recip­i­ent of infor­ma­tion. You may have heard the expres­sion “Cells that fire togeth­er wire togeth­er”. Our brains are com­posed of bil­lions of neu­rons, each of which can have thou­sand of con­nec­tions to oth­er neu­rons. Any thing we do in life is going to acti­vate a spe­cif­ic net­works of neu­rons. Visu­al­ize a mil­lion neu­rons fir­ing at the same time when you watch a TV pro­gram. Now, the more TV you watch, the more those neu­rons will fire togeth­er, and there­fore the more they will wire togeth­er (mean­ing that the con­nec­tions between them become, phys­i­cal­ly, stronger), which then cre­ates auto­mat­ic-like reac­tions. A heavy TV-watch­er is mak­ing him­self or her­self more pas­sive, unre­flec­tive, per­son. Exact­ly the oppo­site of what one needs to apply the oth­er tips described here. Con­tin­ue Reading
