Primary Outcome Measures

Name	Time	Method
The difference between the average reaction time for incongruent trials (at the location of the neutral stimulus) and congruent trials (at the location of the itch stimulus) during the post-ABM training dot-probe task will be the primary outcome measure. This outcome measure will be compared across the three conditions, while taking into account the respective reaction times during the pre-ABM dot-probe task.

Secondary Outcome Measures

Name	Time	Method
Secondarily, self-ratings of experienced itchiness of the cowhage stimulus on a visual analogue scale (VAS) will be compared post-training between the three conditions, while taking into account the VAS itch scores of the cowhage stimulus pre-training. <br /><br>Thirdly, the reaction times for congruent and incongruent trials at baseline (pre-ABM training) will be compared within the entire group.<br /><br>Eye-movements towards pictorial itch and neutral stimuli will be exploratively compared. The ABM training effect will be exploratively associated with individual characteristics.
