“…SCA, which represents sympathetic nervous activity, reflects the method used for our data collection as being exosomatic and conductance as opposed to endosomatic and resistance (for a full discussion, see Khazan, ). Consistent with recommendations from physiology experts (Fish, Russoniello, & Clemmons‐James, ; Khazan, ) for comparing tonic (i.e., baseline sympathetic arousal) and phasic (i.e., amount of change in sympathetic arousal with the inclusion of a stimulus) trends, an aggregated mean SCA score was calculated individually for the baseline, RW with partner, and RW with friend tasks for comparison purposes. Of note, SCA is responsive to movement, talking, being startled, and several other events.…”
