“…Following the ideas of Darwin ( 1872 ) and James ( 1884 ) that it is the afferent signals from the body which elicit emotions and feelings, several theorists in the field of emotion have postulated that sensory feedback from facial and postural movements contribute significantly to emotional experience (Tomkins, 1962 ; Laird, 1974 ; Izard, 1993 ). Indeed, a number of studies have demonstrated that feelings and attitude are affected by changing proprioceptive input from the muscles and joints through the adoption or mimicry of a certain facial expression, (McIntosh, 1996 ; Carr et al, 2003 ; Davis et al, 2009 ), posture (Riskind and Gotay, 1982 ; Duclos et al, 1989 ; Cacioppo et al, 1993 ; Stepper and Strack, 1993 ; Neumann and Strack, 2000 ; Duclos and Laird, 2001 ; Carney et al, 2010 ), head movement (Briñol and Petty, 2003 ; Forster, 2004 ), isometric muscle contraction in the arms (Cacioppo et al, 1993 ; Neumann and Strack, 2000 ), or certain expressive whole-body movements (Duclos and Laird, 2001 ; Shafir et al, 2013 ). It has further been demonstrated that combining both facial and bodily expressions of a certain emotion has a cumulative effect, producing stronger feelings of the corresponding emotion than do either bodily or facial expression alone (Flack et al, 1999 ).…”
