Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Attention and psychomotor speed | 8 min online task on 4 timepoints (n=4) on all experimental days (n=4) | Attention and psychomotor speed is assessed using the Psychomotor Vigilance Task (PVT). The reaction times to optical stimulus (red dot) on the screen, measured in milliseconds will be used as a measure. | ClinicalTrials.gov |
| Primary | Memory | 6 min online task on 4 timepoints (n=4) on all experimental days (n=4) | Memory is assessed using the N-back letter task. The reaction times for correct answers (was the letter on the screen displayed one/two/three letters ago? Yes or No), measured in milliseconds will be used as a measure. | ClinicalTrials.gov |
| Primary | Emotion recognition | 4 min online task on 4 timepoints (n=4) on all experimental days (n=4) | Emotion recognition is assessed using the Karolinska Directed Emotional Faces. The reaction times for correct answers (what emotion does the person on the picture show? Anger, Fear, Disgust, Happiness, Sadness, Surprise), measured in milliseconds will be used as a measure. | ClinicalTrials.gov |
| Primary | Executive function | 5 min online task on 4 timepoints (n=4) on all experimental days (n=4) | Executive function is assessed using the Stroop colour and word task. The reaction times for correct answers (name the word and name the colour of the word), measured in milliseconds will be used as a measure. | ClinicalTrials.gov |
