Research subjects wanted for a study on how to improve your working memory

We are looking for young adults who are interested in improving their working memory with the help of working memory training.

Previous studies have shown that this type of working memory training leads to an improvement in concentration and spatial intelligence.


The aim of the study is to understand the mechanisms behind the improvement of working memory capacity, which could, for example, help people with reduced working memory who often suffer from concentration and learning difficulties.

This is how it works

You will participate in a training program where you train your working memory for 25 minutes per weekday for eight weeks. You do the training from home via an app designed by CogMed, a company that develops programs for cognitive training. The company is not involved in the study.

On seven occasions during the training period, your brain activity will be measured using MEG while performing both trained and untrained working memory tasks. The measurements take place at KI in Solna. Each examination lasts for about an hour and a half.

MEG is a completely harmless instrument that measures magnetic activity in the brain. During the training period, you will also do a Magnetic Resonance Imaging (MRI) on KI, which is needed to analyze MEG data.

The MRI lasts for about 30 minutes. MRI is a method that uses a magnetic camera to image the brain.

Who are we looking for?

We are looking for participants between 18 - 25.

Due to the MRI scan, you should not participate if you have claustrophobia or magnetic metal implants (pacemakers, brain simulators). Pregnant women should also avoid MRI scans and should therefore not participate in the study.

Because MEG measures magnetic fields, you should, in addition to not having metal implants, not wear glasses or braces.

Compensation and insurance

For each measurement occasion, a compensation of SEK 300 / hour is given. The compensation is taxable. We do not compensate for lost earnings, but compensate for travel expenses. All compensation is paid after the last measurement. Patient insurance applies.

Dates for the study

7 February to 31 March 2022.

Responsible for the study
