Physiological measurements of MPA (e.g., Abel and Larkin, 1990 ; Brotons, 1994 ; Yoshie et al, 2009 ; Wells et al, 2012 ; Kenny et al, 2013 ; Studer et al, 2014 ; van Fenema et al, 2017 ; Gomez et al, 2018 ) have also been used as indicators of physiological arousal resulting from activation of the sympathetic division of the Autonomic Nervous System (ANS), for example heart rate, skin conductance, blood pressure, hormone levels, muscle tension and respiration ( Studer et al, 2014 ).…”
