“…In total, there are 27 distinct types of behaviour that can either be considered individually or be classified according to broader behaviour categories. The modified version, used previously by Dimic et al [11], focuses on 14 of these distinct behaviours which can be grouped together to form 6 broader categories ( Table 1). The behavioural categories used, and relevant behaviours within these categories, are as follows: prosocial (look at the interviewer, smile, nod), flight (look down, crouch, look away, freeze), assertion (lean forward), gesture (variable hand and arm movement used during speech), displacement (handface movements, fumbling), and relaxation (fold arm across chest, laugh, neutral face).…”
