The role of exteroceptive and interoceptive awareness in executing socially relevant bodily actions: A naturalistic investigation of greeting behaviour in the UK and Spain

Body awareness is tightly linked to motor action. Non-verbal greetings constitute a behaviour through which an awareness of both socio-cultural habits (exteroceptive awareness) and internal bodily states (interoceptive awareness) play out to influence the structure of action. To establish the effect of culture on non-verbal greeting behaviours, naturalistic observations were carried out in two countries (Britain and Spain) that are purported to exhibit differences in greeting types. Interoceptive awareness (IA) was subsequently measured in a proportion of observed participants ( N = 33) who filled in the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2). As expected, a significant difference in greeting type was observed between British ( N = 252) and Spanish ( N = 244) greeters. Scores of greeting intimacy and competency did not differ significantly between Britain and Spain. However, independent of culture, several moderate and strong relationships emerged between selective dimensions of the MAIA-2 and scores of intimacy and competency. Specifically, intimacy and competency scores were positively correlated with the ‘Awareness of Mind-Body Integration’ dimension. Greeting intimacy yielded additional positive relationships with the Not Distracting and Trusting subscales, and a negative relationship with the Not Worrying subscale. These relationships suggest that IA facilitates healthy social approach behaviour as expressed through greetings, irrespective of cultural greeting differences. We discuss IA and greeting behaviour in the context of attachment, consider the clinical implications for social anxiety and the future implications for social interactions in a post-COVID-19 era.
