“…The ability to automatically (unconsciously) mimic or imitate the facial expressions of others is a fundamental aspect of social behavior and is linked to various outcomes such as liking, dyadic rapport, emotional contagion, and the perception and interpretation of emotions ( Vaughan and Lanzetta, 1981 ; Brothers, 1990 ; Hatfield et al, 1992 ; Cappella, 1993 ; Lundqvist and Dimberg, 1995 ). Unfortunately, this critical mimicking reflex is impaired in individuals with clinical disorders such as depression ( Sloan et al, 2002 ; Zwick and Wolkenstein, 2017 ), alexithymia ( Schiano Lomoriello et al, 2021 ), and other disorders ( McIntosh et al, 2006 ; Varcin et al, 2010 ; Peter-Ruf et al, 2017 ; Passardi et al, 2019 ; Ziebell et al, 2021 ). There is even evidence that non-clinical samples with negative moods ( Ingram and Hamilton, 1999 ) also have disrupted automatic mimicry ( Sloan et al, 2002 ; Lautzenhiser, 2003 ), pointing to the possibility that even mild negative mood (NM) can disrupt mimicry behavior.…”
