“…Specific findings include synchrony in body movement (Ramseyer & Tschacher, 2011), vocal prosody (e.g., pitch, intonation, accent, rhythm and loudness, use of pauses; Couper-Kuhlen, 2012; Weiste & Peräkylä, 2013, 2014), as well as physiological synchrony such as changes in skin-conductance (Marci et al, 2007; see also early studies on heart-rate, Di Mascio, 1955; and emotional reactivity, Lacey, 1959). In general, these studies have shown that greater synchrony is correlated with better ratings of therapist empathy and other measures of the therapeutic relationship, and treatment outcome (see Reich et al, 2014 for an exception).…”
