Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Attention network alerting component:in the behavioral test, a cross (+) is displayed in the center of the screen, with flankers in the form of congruent (>>><>>>>) above or below it appear. Participants are required to focus on the cross during the test period and when the flankers appear, with high speed and accuracy in the direction of the central arrow using the mouse (the left mouse key for when the central arrow tip is to the left and the key the right side of the mouse when the tip of the central arrow is to the right). The alert component is obtained from the fraction of the reaction time and the number of errors of the central sign from the alarm without a sign. Timepoint: After randomization into two experimental and control groups, the pre-test is performed, then the intervention is carried out in 10 sessions and transcranial stimulation is applied in 3 sessions every week for 20 beats, then the post-test is performed. Method of measurement: Attention network test, quantitative electroencephalography.;Orientation component of the attention network: the orientation component is obtained from the fraction of the reaction time and the number of spatial cue errors from the central cue. Timepoint: After randomization into two experimental and control groups, the pre-test is performed, then the intervention is carried out in 10 sessions and transcranial stimulation is applied in 3 sessions every week for 20 beats, then the post-test is performed. Method of measurement: Attention network test, quantitative electroencephalography.;Executive component of attention network:The executive control component is obtained from the fraction of the reaction time and the number of errors of the incongruent arrows from the congruent ones. Timepoint: After randomization into two experimental and control groups, the pre-test is performed, then the intervention is carried out in 10 sessions and transcranial stimulation is applied in 3 sessions every week for 20 beats, then the | — |
