“…We recruited actors to address this question because of the centrality of accurate self-perception and awareness to their profession generally, and especially within the domain of physiology and emotion (Gosselin et al, 1995; Stanislavsky, 1952; Strasberg, 1987). Because of the established connection between interoception and emotional experience (Barrett et al, 2004; Critchley et al, 2004; Khalsa et al, 2018; Wiens et al, 2000), empathy (Ernst et al, 2013; Heydrich et al, 2021; Terasawa et al, 2014), and emotion regulation (Kever et al, 2015), we think it likely that the enhanced metacognitive awareness in actors identified here will facilitate actors’ emotion-related abilities, as the awareness of the perception of internal physiological signals would likely be relevant to the ability to effectively create, express, and convey emotion as an actor, though this is of course an empirical question. There is also the potential for these factors to be additionally related to other important emotion constructs like emotional awareness or intelligence (e.g., Ashkanasy & Dasborough, 2003; Lane et al, 1990; Salovey & Grewal, 2005), emotion expression (e.g., Elfenbein et al, 2002; Matsumoto et al, 2008), or affective synchrony (e.g., Wood et al, 2021) which could be examined by future studies.…”
