“…Three different mechanisms, that are not necessarily exclusive, might underlie such a mouth activation (for details see Borghi et al, 2019): (A) Reenactment of the past experience of acquiring abstract concepts, which typically occurred through the verbal linguistic mediation (Granito et al, 2015;Barca et al, 2017Barca et al, , 2020Mazzuca et al, 2018). (B) Re-explanation to ourselves of the word meaning, through the use of inner speech (Zannino et al, 2021;Villani et al, 2021;Dove et al, 2020;Borghi, 2020). (C) A motor preparation to ask additional explanations of word meaning to others, derived from the feeling of uncertainty and the metacognitive awareness that the owned knowledge of that concept is scarce and not adequate (i.e., Social Metacognition, Borghi et al, 2019;Fini & Borghi, 2019; see Borghi, Fini, & Tummolini, 2021;Borghi, 2020;Dove et al, 2020; see also Prinz, 2012;Shea, 2018).…”
