Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will test if cued self-generated expectations affect pain processing. Our main aim is to assess time-frequency (EEG) neural characteristics of self-generated positive and negative expectations on pain in the expectation phase directly prior to the application of painful stimuli. | — |
Secondary
| Measure | Time frame |
|---|---|
| In addition, we will examine neural processes after the cue presentation and during the application of the pain stimuli. | — |
