Problems With The System Of Facial Affect

Ngo, Hood, Martin, Painter, Smith & Zappavigna (2022: 120, 121):

The systemic functional semiotic system of FACIAL AFFECT presented in Figure 5.3 takes into account these important contributions in a number of areas, including descriptive terminology. For example, the naming of features in the model of FACIAL AFFECT avoids the use of Ekman’s terms of ‘happiness’ and ‘sadness’ as [happiness] is already a feature in linguistic ATTITUDE. Instead emotion terminology is sourced to Darwin’s (1872) opposition in facial movements of ‘high spirit’ and ‘low spirit’. Darwin’s influence is seen in Figure 5.3 in the naming of the feature [spirit] and its opposing features as [up] and [down].

[1] To be clear, the system in Figure 5.3 confirms the fact that here the authors model paralanguage as a bi-stratal semiotic system. As previously noted, although this is consistent with the notion of a semiotic system, it is inconsistent with the preceding chapters in which paralanguage is misunderstood as an expression-only semiotic system. Where in previous chapters it was just paralinguistic expression that was semovergent with language, in this chapter it is both paralinguistic content and expression that is semovergent with language.

[2] To be clear, the title of Darwin (1872), The expression of the emotions in man and animals, acknowledges that the expression of emotion does not require the evolution and development of language. As such, the facial expression of emotion is protolanguage, not language.

Where AFFECT is a system of the interpersonal metafunction in the tri-stratal semiotic of language, protolanguage is a bi-stratal system that is pre-metafunctional. On Halliday's model, the expression of emotion serves the personal microfunction. 

In short, to model the personal microfunction of protolanguage as the interpersonal metafunction of language, as FACIAL AFFECT, is theoretically invalid.
