Wikipedia says “Recent stud­ies sug­gest that Work­ing Mem­ory can be improved by work­ing mem­ory train­ing (Kling­berg et al., 2002)…Per­haps of greater impor­tance, another study has found after a period of work­ing mem­ory train­ing an increase in a range of cog­ni­tive abil­i­ties and an increase in IQ test scores of approx­i­mately 8%.”

A search for “Torkel Kling­berg” in PubMed returns 26 papers pub­lished in peer-reviewed pub­li­ca­tions such as the Jour­nal of the Amer­i­can Acad­emy of Child & Ado­les­cent Psy­chi­a­try, Jour­nal of Cog­ni­tive Neu­ro­science, and Nature Neu­ro­science.

We are happy to launch our Neu­ro­sci­en­tist Inter­view Series with an inter­view with Dr. Torkel Kling­berg.

Alvaro Fer­nan­dez (AF): Wel­come. Can you let us know where you work, and what your Lab does?

Dr. Torkel Kling­berg (TK): I have a pro­fes­sor­ship at Karolin­ska Insti­tute, and lead the Devel­op­men­tal Cog­ni­tive Neu­ro­science Lab, part of the Stock­holm Brain Insti­tute. The lab is address­ing the ques­tions of devel­op­ment and plas­tic­ity of work­ing mem­ory. We do that through sev­eral tech­niques, such as fMRI, dif­fu­sion ten­sor imag­ing to look at myeli­na­tion of white mat­ter in the brain, neural net­work mod­els of work­ing mem­ory and behav­ioral stud­ies. In addi­tion, I am a sci­en­tific advi­sor for Cogmed, the com­pany that devel­oped and com­mer­cial­izes RoboMemo.

AF: What stud­ies have you pub­lished so far? What stud­ies are in the pipeline, and will be pub­lished soon?

TK: You can find a com­plete list, and the stud­ies them­selves, at the lab home­page. Among our stud­ies are three stud­ies on the effect of work­ing mem­ory train­ing: Kling­berg et al. 2002, 2005 and Ole­sen et al. 2004. We have recently sub­mit­ted two papers on the effect of train­ing in com­bi­na­tion with med­ica­tion, and the effect of train­ing on school performance.

AF: What are the high­lights of your research so far?

TK: Our paper from 2004 in Nature Neu­ro­science, on the effect of work­ing mem­ory train­ing on brain activ­ity, and the 2005 ran­dom­ized, con­trolled clin­i­cal trial that showed the impact of work­ing mem­ory train­ing specif­i­cally in kids with ADD/ ADHD, have caught most pub­lic atten­tion, includ­ing ref­er­ences in Sci­en­tific Amer­i­can.

My other research con­cerns the neural basis for devel­op­ment and plas­tic­ity of cog­ni­tive func­tions dur­ing child­hood, in par­tic­u­lar devel­op­ment of atten­tion and work­ing mem­ory.
In short, I’d say that we have shown that work­ing mem­ory can be improved by train­ing and that such train­ing helps peo­ple with atten­tion deficits and it also improves rea­son­ing abil­ity overall.

AF: What are the effects in every-day life for a child with atten­tion deficits?

TK: When look­ing at the 1,200 chil­dren who have trained in Cogmed’s Stock­holm Clinic since start, the most com­mon effects are sus­tained atten­tion, bet­ter impulse con­trol and improved learn­ing abil­ity. Par­ents often report that their chil­dren per­form bet­ter in school and are able to keep up a coher­ent con­ver­sa­tion more eas­ily after train­ing. Being able to hold back impulses, such as anger out­bursts, and keep­ing bet­ter track of one’s things are other every-day life benefits.

AF: How are you mak­ing the pro­gram available?

TK: All rights are with Cogmed, who is mak­ing this avail­able in Swe­den and start­ing to offer this to selected clin­ics in the US this year. The pro­gram is called RoboMemo Work­ing Mem­ory Train­ing Pro­gram.

AF: What do you expect that we will learn over the next 5 years in the field of Brain Fit­ness Pro­grams and cog­ni­tive training?

TK: I think that we are see­ing the begin­ning of a new era of com­put­er­ized train­ing for a wide range of appli­ca­tions. Our stud­ies has mostly been aimed at indi­vid­u­als with marked prob­lems of inat­ten­tion, but there is a wider zone con­cern­ing what you define as atten­tion prob­lems, and we will see how RoboMemo can help a larger part of the pop­u­la­tion in improv­ing cog­ni­tive function.

AF: What will you talk about at CHADD?

TK: I will present the data from our pub­lished stud­ies on ADHD, as well as some new data from inde­pen­dent researchers in US uni­ver­si­ties that con­firm our find­ings con­cern­ing the effect of work­ing mem­ory training.

AF: You are writ­ing a book, cor­rect? what is it about?

TK: The book is a pop­u­lar sci­ence book about work­ing mem­ory, in the lab and in daily life. It will be out in March in Swe­den and we are cur­rently look­ing for a US publisher.

AF: Dr. Kling­berg, thanks for your time.

TK: My pleasure.
