What is mental exercise or “brain training”?

nIn Ses­sion 2 we showed that brain main­te­nance includes bal­anced nutri­tion, stress man­age­ment, phys­i­cal exer­cise and brain exer­cise. We also report­ed that numer­ous stud­ies have shown that intel­lec­tu­al activ­i­ty in gen­er­al is good for the brain and may help build up cog­ni­tive reserve.

The next ques­tion we need to clar­i­fy is, How is brain train­ing or brain exer­cise dif­fer­ent from dai­ly men­tal activ­i­ties? Let’s take the exam­ple of phys­i­cal activ­i­ty. There is a clear dif­fer­ence between phys­i­cal activ­i­ty and phys­i­cal exer­cise. Phys­i­cal activ­i­ty occurs when­ev­er we move our body or engage in a leisure activ­i­ty that involves mov­ing our body (e.g., play­ing pool). Phys­i­cal exer­cise (e.g. jog­ging) refers to the repeat­ed and struc­tured activ­i­ty of par­tic­u­lar parts of our bod­ies. While both phys­i­cal activ­i­ty and phys­i­cal exer­cise may bring ben­e­fits, it is the lat­ter that helps build capac­i­ty and mus­cles strength, con­tribut­ing to stay­ing fit as we age.

Sim­i­lar­ly, brain “train­ing”, or brain “exer­cise”, goes beyond men­tal activ­i­ty. Men­tal activ­i­ty takes place when­ev­er one is awake, rang­ing from mere­ly day dream­ing to read­ing a book or learn­ing a new lan­guage. Men­tal exer­cise or brain train­ing refers to the struc­tured use of cog­ni­tive exer­cis­es or tech­niques. Its aim is to improve spe­cif­ic brain func­tions.

Under­stand­ing the dif­fer­ence between men­tal activ­i­ty and men­tal exer­cise is cru­cial. For instance, many peo­ple feel that they are doing the best for their brain after hav­ing com­plet­ed their dai­ly puz­zle. How­ev­er cross­word puz­zles chal­lenge a rel­a­tive­ly nar­row range of cog­ni­tive skill and thus stim­u­late only a lim­it­ed range of brain regions. A 1999 study showed that increased amount of expe­ri­ence in doing cross­word puz­zles does not mod­i­fy the effect of age mea­sured in tasks requir­ing vocab­u­lary and rea­son­ing (Ham­brick et al.,1999). Cross­words puz­zles gen­er­ate men­tal activ­i­ty but they do not con­sti­tute a brain train­ing pro­gram!

This points out to the key word in brain train­ing: vari­ety. One needs a vari­ety of chal­leng­ing exer­cis­es in order to stim­u­late the whole brain. Recent rec­om­men­da­tions made by a pan­el of experts review­ing a poll by the Amer­i­can Soci­ety on Aging (2006) stat­ed: “A sin­gle activ­i­ty, no mat­ter how chal­leng­ing, is not suf­fi­cient to sus­tain the kind of men­tal acu­ity that vir­tu­al­ly every­one can achieve.” Even if one’s goal is to improve mem­o­ry func­tions, oth­er brain func­tions need stim­u­la­tion to achieve that goal. For instance, atten­tion and con­cen­tra­tion are essen­tial to good mem­o­riza­tion.

Sys­tem­at­ic brain train­ing pro­grams can be designed to lead to brain change in a more effi­cient way that ran­dom dai­ly activ­i­ties may. A com­bi­na­tion of both may be ide­al. Learn­ing a com­plex skill such as learn­ing the piano helps train and devel­op some parts of the brain. Well-designed train­ing pro­grams may help train and devel­op oth­er parts.
Defined as the struc­tured use of cog­ni­tive exer­cis­es or tech­niques aimed at improv­ing spe­cif­ic brain func­tions, brain train­ing includes a range of research-sup­port­ed tech­niques or approach­es, such as cog­ni­tive ther­a­py and med­i­ta­tion, along with the most pop­u­lar brain fit­ness soft­ware. This guide is focused on soft­ware pro­grams but will also dis­cuss oth­er approach­es.
