Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is similar for both itch and pain, and concerns one*s capacity to disengage attention. Attentional disengagement from itch or pain is reflected by the reaction time of responses to ipsilaterally (as opposed to the itch/pain stimulus) versus contralaterally presented visual targets during the itch and pain stimuli, respectively, corrected for the reaction time during control blocks (i.e. without somatosensory stimulus). | — |
Secondary
| Measure | Time frame |
|---|---|
| As secondary outcome, the accuracy (i.e. incorrect responses) of the reactions to the visual targets will be determined during the itch and pain blocks, corrected for the control blocks. Exploratory, the degree of attentional disengagement from itch will be compared to the degree of attentional disengagement from pain, both with respect to the reaction times and the accuracy. Moreover, individual characteristics assessed by self-report questionnaires will exploratory be related to attentional disengagement from itch and pain. | — |
