Inclusion criteria
Inclusion criteria: All participants will be healthy and pain-free as determined by self-report, between 18 and 75 years of age, and capable of speaking and reading Dutch.

Exclusion criteria: Participants will be excluded when they use psychotropic or analgesic drugs (e.g., opioids such as morphine or tramadol, tricyclic antidepressants such as amitriptyline or nortriptyline, anticonvulsants such as gabapentin or carbamazepine, or antipsychotics such as haloperidol) that affect reaction times or pain perception, or when participants are allergic for Spanish peppers or have psoriasis on one of their hands.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Reaction time (RT) to targets in a visual search task. When an irrelevant distractor is presented during the visual search, attention is captured and response times become longer as compared to no-distractor present trials. This RT effect is expected to vary according to the presence and the spatial position of the painful hand. | — |
Secondary
| Measure | Time frame |
|---|---|
| Detection accuracy, *learnability*; the speed (number of trials necessary) at which a participant learns and *unlearns* a new association between two events; number of trials that are required to learn a new association, saccade latency; delay in response times of eye movements, saccade accuracy; eye movement in the correct direction. | — |
