Martin's Notion Of Commitment

Martin & Zappavigna (2019: 12-3):

In terms of commitment (i.e. the amount of meaning specified across semiotic modes; Martin 2010, Painter et al. 2013), the dermatologist and steroid are committed in the language but not the paralanguage; but the needle is more delicately committed in the paralanguage as a tiny pointed entity and then as a syringe. 

And the paralinguistic commitment of the bump in fact takes place two tone groups after it is committed verbally.

[1] To be clear, Martin's notion of 'commitment' is invalidated by the fact that it is based on a fundamental misunderstanding of the system network, namely: that a speaker can choose the degree of delicacy to be instantiated during logogenesis.  As Martin (2011: 255-6) explains:

Instantiation also opens up theoretical and descriptive space for considering commitment (Martin 2008, 2010), which refers to the amount of meaning instantiated as the text unfolds.  This depends on the number of optional systems taken up and the degree of delicacy pursued in those that are, so that the more systems entered, and the more options chosen, the greater the semantic weight of a text (Hood 2008).

To be clear, a system network is not a type of flowchart, such that instantiation involves a movement through more and more delicate systems.  A system network is a network of relations.  In the case of lexicogrammar, the system specifies how all the features are related to each other, such that the instantiation of each lexical item in a text is the instantiation of all the features that specify it, from the most general all the way to the most delicate.

In short, Martin misconstrues what the linguist can do — decide on the degree of delicacy "pursued" in analysing a text — as what a speaker can do; but see also [3] below.

[2] Translating into SFL theory, the claim here is that the meanings 'dermatologist' and 'steroid' are instantiated in the language but not in paralanguage.  However, this is manifestly untrue.  As previously explained, the body of the speaker herself represented the dermatologist in two figures ('taking the needle' and 'injecting the steroid').

The instantiation of the meaning 'steroid' is more subtle.  Because, as Halliday & Matthiessen (1999: 156) point out, a Process requires a Medium for its actualisation, the gesture representing the 'injecting' Process implicates a Medium, and so the meaning 'fluid' is at least implicated in the gesture, even if the meaning 'steroid' is not precisely specified.  (Try gesturing the meaning 'steroid'.)

To be clear, the authors' false claim derives from two procedural errors:

• assuming that handshape is the only bodily expression of ideational meaning here, and
• analysing at the level of element ("entity") instead of figure (while claiming the latter).

[3] As explained in [1], Martin's notion of "more delicate commitment" is nonsensical, based as it is on his misunderstanding of what system networks represent.

However, here it can also be seen that Martin confuses 'delicacy' as a scale of decreasing generality in system networks with 'delicacy' as a scale of decreasing generality in construing experience as meaning, as in 'needle' vs 'tiny pointed entity'.   It can also be seen that, even in these terms, the authors have the relation backwards, since 'tiny pointed entity' is a more general construal than 'needle', not more delicate, since, as a class, it includes a broader range of potential members.

[4] To be clear, the word 'syringe' is not instantiated in the data.  It appears only in the authors' gloss of the body language accompanying the wording and injected this like steroid.

[5] As explained in the previous post, the reason why this gesture is made with the final figure, and not the second, is that it realises the nucleus of the final figure, it all bubbled up, rather than the meaning of the word bump in the second figure.  The authors' confusion again arises from analysing isolated elements instead of their functions in figures.
