Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Secondarily, generalization to another stimulus modality will be investigated by comparing the conditions on the attentional bias index for the word stimuli and differences in sensitivity to touch evoked itch will be assessed across conditions. It is planned to explore the temporal dynamics of attention allocation over time (e.g., Davis et al., 2016, Zvielli et al., 2016) for both the itch pictures and words across the conditions.
