Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameters are the measurements regarding emotion regulation that are associated with fear and pill use in adults: the extent of fear acquisition and extinction by subjective measures and skin conductance (during the emotion regulation experiments). | — |
Secondary
| Measure | Time frame |
|---|---|
| The other study parameters include the Late Positive Potential (LPP) as a neural marker and electromyographie (EMG) as a physical marker for emotional reactivity that is modulated by emotion regulation (during the emotion regulation experiments) , and cortisol, self-evaluation and task performance changes after induced psychosocial stress (during the stress experiments), and mood questionnaires. These different study parameters are included to form a comprehensive view on the effects of the pill on neural, physiological and psychological processes underlying depression and anxiety in adolescents. | — |
