Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Blood oxygen level dependent (BOLD) signal in the brain measured by functional magnetic resonance imaging during the pretest (within few weeks before the cognitive training) and the posttest (within few weeks after the cognitive training). Due to the study’s experimental design, BOLD signal is assessed in different conditions (during working memory task, rest, and movie watching) and can be analysed in several ways, including regional activity and their temporal correlations. | — |
Secondary
| Measure | Time frame |
|---|---|
| White matter properties of the brain measured by diffusion-weighted magnetic resonance imaging during the pretest (within a few weeks before the cognitive training) and the posttest (within a few weeks after the cognitive training). White matter properties can be analysed in several ways, including microstructure and tractography. | — |
