Do you remem­ber the IMPACT study pub­lished in 2009? It was a ran­dom­ized clin­i­cal trial with healthy older adults that com­pared a computer-based cog­ni­tive pro­gram that trains audi­tory pro­cess­ing (Brain Fit­ness Pro­gram, Posit Sci­ence) with edu­ca­tional video pro­grams (con­trol group). Peo­ple who used the pro­gram improved in the trained tasks, which was not that sur­pris­ing, but there was also a clear ben­e­fit in audi­tory mem­ory, which wasn’t directly trained.

A 2011 paper reports the 3-month follow-up results of the IMPACT study. The 487 par­tic­i­pants in the orig­i­nal study were 65 and older. Train­ing was 1 hour a day, 4 to 5 days a week, for a total of 40 hours in 8 to 10 weeks. There was no con­tact with the researchers between the ini­tial train­ing study and the follow-up study.

The results showed that 3 months after the ini­tial train­ing most of the improve­ment observed in the train­ing group was still present, although not as strongly. Read the rest of this entry »

There 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 Train­ing: No Magic Bul­let, Yet Use­ful Tool. Inter­view with Eliz­a­beth Zelin­ski: Dr. Zelin­ski, lead­ing researcher of the IMPACT study, shares fas­ci­nat­ing insights. For exam­ple: “…cog­ni­tive enhance­ment requires the engage­ment in a vari­ety of activ­i­ties, those activ­i­ties must be novel, adap­tive and challenging-which is why computer-based pro­grams can be help­ful. But even at a more basic level, what mat­ters is being engaged with life, con­tin­u­ally exposed to stim­u­lat­ing activ­i­ties, always try­ing to get out of our com­fort zones, doing our best at what­ever we are doing. A major typ­i­cal mis­con­cep­tion is that there is only one gen­eral intel­li­gence to care about. In real­ity, we have many dif­fer­ent cog­ni­tive abil­i­ties, such as atten­tion, mem­ory, lan­guage, rea­son­ing, and more, so it makes sense to have dif­fer­ent pro­grams designed to train and improve each of them.”

Sharon Beg­ley, Newsweek’s sci­ence reporter, recently wrote that

- “With the nation’s 78 mil­lion baby boomers approach­ing the age of those dreaded ‘“where did I leave my keys?” moments, it’s no won­der the mar­ket for computer-based brain train­ing has shot up from essen­tially zero in 2005 to $80 mil­lion this year, accord­ing to the con­sult­ing firm SharpBrains.

- “Now comes the largest and most rig­or­ous study of a commercially-available train­ing pro­gram, and it shows that there is hope for aging brains. This morn­ing, at the meet­ing of the Geron­to­log­i­cal Soci­ety of Amer­ica, sci­en­tists are pre­sent­ing data show­ing that after eight weeks of daily one-hour ses­sions with Brain Fit­ness 2.0 from Posit Sci­ence, elderly vol­un­teers got mea­sur­ably bet­ter in their brain’s speed and accu­racy of processing.

We recently had the chance to inter­view Dr. Eliz­a­beth Zelin­ski of the Uni­ver­sity of South­ern Cal­i­for­nia Andrus Geron­tol­ogy Cen­ter, who led the IMPACT (Improve­ment in Mem­ory with Plasticity-based Adap­tive Cog­ni­tive Train­ing) Study Sharon Beg­ley refers to in the quote above.

First, some con­text on this study, which is by far the largest high-quality study of its kind. The study was prospec­tive, ran­dom­ized, con­trolled, and used a dou­ble blind trial. 524 healthy adults 65-year-old and over were divided into two groups. One received an hour a day of train­ing for eight to ten weeks, and the other spent the same amount of time watch­ing edu­ca­tional DVDs. The IMPACT study, funded by Posit Sci­ence cor­po­ra­tion, was per­formed in mul­ti­ple loca­tions, includ­ing the Mayo Clinic, USCF, and San Fran­cisco Vet­eran Affairs Med­ical Center.

The dis­cus­sion cen­ters at his point on the ini­tial results that were pre­sented Geron­to­log­i­cal Soci­ety of Amer­ica (the study hasn’t been pub­lished yet).

Alvaro Fer­nan­dez: Dr. Zelin­ski. Thank you for being with us. Could you start by set­ting the con­text and pro­vid­ing an overview of how human cog­ni­tive abil­i­ties typ­i­cally evolve as we age based on insights from your Long Beach Lon­gi­tu­di­nal Study?

Eliz­a­beth Zelin­ski: Of course. The first con­cept to under­stand is that dif­fer­ent cog­ni­tive skills evolve over the lifes­pan in dif­fer­ent ways. Some that rely on expe­ri­ence, such as vocab­u­lary, actu­ally improve as we age. Some tend to decline grad­u­ally, start­ing in our late 20s. This hap­pens, for exam­ple, with pro­cess­ing speed (how long it takes us to process and respond to infor­ma­tion), mem­ory, and rea­son­ing. We could sum­ma­rize this phe­nom­e­non by say­ing that as we age we get bet­ter at deal­ing with the famil­iar, but worse at deal­ing with the new. We can always learn, but at a slower pace.

Are there any spe­cific tip­ping or inflec­tion points in this trend, any age when the rate of decline is more pronounced?

We don’t have a clear answer to that. It depends a lot on the indi­vid­ual. In gen­eral it is a grad­ual, cumu­la­tive process, so that by age 70 we sta­tis­ti­cally see clear age declines. Which, for exam­ple, is a strong fac­tor deter­min­ing why older adults strug­gle to adapt to new tech­nolo­gies, but why try­ing to learn them pro­vides needed men­tal stim­u­la­tion. Now we know that genes only account for a por­tion of this decline. Much of it depends on our envi­ron­ment, lifestyle and actions.

Can you sum­ma­rize what a healthy indi­vid­ual can do to slow down this process of decline, and help stay healthy and pro­duc­tive as long as possible?

One gen­eral rec­om­men­da­tion is to do every­thing we can to pre­vent or delay dis­ease processes, such as dia­betes or high-blood pres­sure, that have a neg­a­tive effect on our brains. For exam­ple, it is a tragedy in our soci­ety that we usu­ally reduce our lev­els of phys­i­cal exer­cise dras­ti­cally after we leave school.

Let me then ask: what are the rel­a­tive virtues of phys­i­cal vs. men­tal exercise?

Great ques­tion! That in fact leads into my sec­ond rec­om­men­da­tion. Aer­o­bic exer­cise has been shown to Read the rest of this entry »

Quick: say the color in which each word in this graphic is dis­played (don’t just read the word!):

Here you have a round-up of some great recent arti­cles on mem­ory, aging, and cog­ni­tive abil­i­ties such as self-control:

1) How to Boost Your Willpower (New York Times).

- “The video watch­ers were later given a con­cen­tra­tion test in which they were asked to iden­tify the color in which words were dis­played. (Note: now you see why we started with that brain exer­cise…) The word  for instance, might appear in blue ink. The video watch­ers who had sti­fled their responses did the worst on the test, sug­gest­ing that their self-control had already been depleted by the film challenge.”

- “Finally, some research sug­gests that peo­ple strug­gling with self-control should start small. A few stud­ies show that peo­ple who were instructed for two weeks to make small changes like improv­ing their pos­ture or brush­ing their teeth with their oppo­site hand improved their scores on lab­o­ra­tory tests of self-control. The data aren’t con­clu­sive, but they do sug­gest that the quest for self-improvement should start small. A vow to stop swear­ing, to make the bed every day or to give up just one food may be a way to strengthen your self-control, giv­ing you more willpower reserves for big­ger chal­lenges later.”

Com­ment: learn­ing, build­ing abil­i­ties, are processes that require prac­tice and grow­ing lev­els of dif­fi­culty. Like train­ing our mus­cles in the gym. So the advice to start small and pro­gres­sively do more makes sense. Many times the enemy of learn­ing is the stress and anx­i­ety we pro­voke by try­ing to do too many things at the same time…

2) Jog­ging Your Mem­ory (Newsweek) Thanks Chris for alert­ing us!

- “No one should expect mir­a­cles soon, if at all. But the deeper sci­en­tists peer into the work­ings of mem­ory, the bet­ter they under­stand Read the rest of this entry »
