“…Low levels of resting respiratory sinus arrhythmia (RSA), for example, have been consistently associated with dysfunctional emotional traits, such as aggression (Gordis, Feres, Olezeski, Rabkin, & Trickett, 2010), anxiety (Watkins, Grossman, Krishnan, & Sherwood, 1998), and depression (Carney et al, 1995).
