“…Finally, more objective estimations of the size and characteristics of the EM vocabulary were provided by testing children's ability to label faces, stories or vignettes describing feelings (Grosse et al, 2021;Streubel et al, 2020;Widen & Russell, 2003, 2008, listing as many emotion words as they knew (Beck et al, 2012) or asking definitions for EM words (Nook et al, 2020). Overall, these studies show that most children between 28 and 36 months have already learnt words describing feelings such as funny, love or scared (Bretherton & Beeghly, 1982;Nook et al, 2017;Ridgeway et al, 1985;Widen & Russell, 2003, 2008, and that EM vocabularies grow quickly at ages 4-11 (Baron-Cohen et al, 2010;Grosse et al, 2021;Li & Yu, 2015;Nook et al, 2020;Streubel et al, 2020). Also, EM words denoting positive affective states are learnt earlier in life compared to those expressing negative feelings (Baron-Cohen et al, 2010;Li & Yu, 2015).…”
