The general idea of a Linguistic Field and a Linguistic Code can be found in the Language & Linguistics section of the Ideas Pages. It is the notion that, within therapy, patient and therapist become locked together via a "linguistic field", i.e. a particular way in which the use of language becomes structured. My speculation is that the linguistic characteristics of this structuring could be used both as a diagnostic tool and as a prognosis for the success of the therapy.
Moving this idea beyond the stage of speculation would require support and collaboration with others.
