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.
