Problems With The Authors' Analysis Of Hand Shape

 Ngo, Hood, Martin, Painter, Smith & Zappavigna (2022: 183-4):

In (17'') we present a sequence of images and descriptions of the lecturer’s paralanguage. …

In terms of size, the beat synchronous with the first tonic on (Foucault) and the last (form of power) extends the furthest, with the stroke of the latter extending maximally downwards from shoulder height. The final beat is also extended in duration as it is held beyond the completion of the tone group.

Variation in the shape of the beating hand is noted in image 4 and magnified in (17''') to reveal the co-instantiation of a depicted paralinguistic entity. In this instance the gestural beat synchronises with self; the pronoun refers anaphorically to the semiotic entity form of knowledge. The paralinguistic beat thus assigns textual prominence to an ideational meaning.

[1] To be clear, this display does not present the text as spoken:

[2] To be clear, this distinction in the amplitude of the beat serves the same function as the distinction between tonic salient syllables and non-tonic salient syllables.

[3] To be clear, the location of the holding of the gesture suggests the function of the holding is demarcative.

[4] Clearly, the hand shape is not recognisable as meaning '(it)self' or 'form of knowledge', so it cannot be said to be realising this ideational meaning. 

[5] To be clear, it is the beat of linguistic gesture, not the hand shape, that gives rhythmic salience, highlighting what could have been chosen as realising the focus of New information, but was not. However, the fact that an emphatic pronoun was not given tonic prominence in this analysis, gives reason to doubt the accuracy of the analysis.
