“…These results related to the relationship between reappraisal, mindfulness and neurophysiological changes are further in line with different models of consciousness, such as the Self-awareness, self-regulation, and self-transcendence (S-ART) model ( Vago and David, 2012 ) and the Sphere Model of Consciousness (SMC, Paoletti, 2002 ; Paoletti and Ben-Soussan, 2019 , 2020 ; Paoletti et al, 2020 ). According to the SMC, reappraisal and voluntary movement toward a state of contentless consciousness, also defined as momentary silent consciousness ( Baars, 2013 ; Josipovic, 2019 ) may have a decisive role in the experience ( Paoletti et al, 2020 ; Paoletti and Ben-Soussan, 2020 ), in which focusing one’s attention on silence can be used as a paradigm for facilitating better internal communication through an internal environment intentionally created ( Paoletti and Selvaggio, 2013 ; Paoletti et al, 2017 ; De Fano et al, 2019 ). Consequently, in this study, silence was operationalized as self-reported absence of thoughts and a subjective experience of mental quietness as suggested by various authors ( Rudrauf et al, 2003 ; Hinterberger et al, 2014 ; Josipovic, 2014 , 2019 ; Winter et al, 2019 ; see Table 1 ), thus describing a state in which participants spontaneously experienced and reported a sort of contentless consciousness.…”
