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