“…However, it seems that the medium of vocal expressions as a bottom-up factor can also influence this peak distribution. Concerning this medium or nature of vocalizations, vocal expressions of emotions can be purely nonverbal, such as laughs, cries, or screams (Sauter et al, 2010;Simon-Thomas et al, 2009), but they can also be superimposed on semantically neutral Kotz et al, 2003;Leitman et al, 2010) and semantically emotional language (Beaucousin et al, 2007;Mitchell, 2006;Mitchell et al, 2003;Schirmer et al, 2004), as well as on pseudospeech (Bach et al, 2008;Sander et al, 2005). Given this distinction between nonverbal vocal expressions and emotional prosody, it might be assumed that emotional intonations superimposed on speech strongly engage the left IFC, whereas nonverbal expressions activate the right IFC (Meyer et al, 2005).…”
