Emotion Regulation Paradigm - MacArthur Reactivity Protocol (MRP)
The MacArthur Reactivity Protocol (Bush et al. 2011) includes challenges across four different task domains and paired baseline tasks. Challenges include a social task (talking with an experimenter); a cognitive task (digit span); a sensory task (receiving two drops of lemon juice on the tongue); and an emotional task (watching an age-appropriate video clip intended to elicit fear). Baseline tasks include talking about pictures in a book for the social domain, an easier digit span task in the cognitive domain, identifying a drop of water for the sensory domain, and watching a neutral video clip for the emotional domain. Baseline tasks were designed to account for the psychomotor demands of the corresponding challenge task and each task lasted up to two minutes.
