- InterventionsThe participants will receive electrocutaneous stimuli while performing either distraction tasks and while actively attending the electrocutaneous stimuli. Distraction tasks are mental-arithmetic tasks, word-association, spatial distraction or n-back task. Active attending of the stimuli is achieved by asking the participant to rate each stimulus on a VAS.
Each participant will perform both the attend condition as well as the distraction condition. With this repeated measures design it will be possible to show the effects of distraction on stimulus processing.
- Primary outcomeThe effects of sustained distraction on the processing of these stimuli will be investigated using EEG measurements. The effect of distraction is observed when the event related potentials (evoked by the electrocutaneous stimuli) are smaller in the distraction conditions compared to the attend conditions. When this is observed one can say that distraction has an attenuating effect on painful stimulus processing.
- Secondary outcomeThe effects of distracting electrocutaneous stimuli on the performance of attention demanding tasks will be measured.
- TimepointsEach experiment is an individual experiment and runs for max 2 to 3 hours.
