Problems With The Authors' Scope And Demarcation Analysis

Ngo, Hood, Martin, Painter, Smith & Zappavigna (2022: 176-7):

In example (15) the PARALINGUISTIC DEIXIS identifies time as [virtual:location] and selects for both SCOPE and DEMARCATION. 

In image 1 in (15), the ‘pinch’ point of left thumb and index finger selects for SCOPE as [narrow], as does the left index finger point in image 2. Both these vectors contrast with the right-hand vector in image 2 where an open palm with spread fingers and thumb configures SCOPE as relatively [broad]. The narrow pinch point in image 1 syncs sonovergently with today and semovergently with the meaning of the narrowly defined time reference. The relatively broad righthand point in image 2 syncs sonovergently with future and semovergently with the relatively open time reference. 

The PARALINGUISTIC DEIXIS in (15) also selects for DEMARCATION as [delineation]. In the second image, the left index finger extends outwards from the body, sustaining its semovergence with today. The left index finger delineates a boundary line, a [virtual:location] from which time stretches into the future, the [virtual:location] identified to the right. Our data suggest that the selection of [virtual:semiotic], whether [prospective] or [retrospective], does not select for either relative SCOPE or DEMARCATION.

[1] As previously explained, this is an example of using body language to make endophoric reference, with the left-right dimension of interpersonal space ideationally construing the past-future dimension of interpersonal time, and the pointing gesture signalling that the meanings 'present' and 'future' are recoverable from those construals by body language. Again, the vector is "resolved" and so the "deixis" is not virtual.

[2] To be be clear, selecting features from systems is the process of instantiation, and it is not a (more inclusive) system that does the selecting.

[3] To be clear, gestures don't instantiate ('select') content plane features, they realise them. That is, the authors here confuse interstratal realisation with system instantiation.

[4] To be clear, it is the expression (hand shape) that is broad or narrow, not the content. As previously explained, on the authors' model, this hand shape realises the ENGAGEMENT feature 'expansion'.

[5] To be clear, the timing of the gesture is linguistic and textual, because, like the tonic, it realises the focus of New information, in this case: today and future.

[6] To be clear, the gesture points to a spatial location that symbolises a temporal location. Any location can be construed as a boundary between other locations, but there is no evidence here that the gesture construes the location as a boundary. This is a case of making the data fit the theory instead of using the theory to account for the data.
