I am also concerned with maintaining avenues of communication and cross-fertilization among various communities of inquiry. We have to observe the specialized ways that terms are used in particular communities but we cannot capitulate to uses so specialized that they obscure the more general meaning.
I completely agree. For any audience, it's important to start with terminology that is familiar to the audience. But when talking about any source, it's best to quote the ipsissima verba of the author(s). As an example, I'm still working on and extending the slides for a talk I presented in July 2016 on "The virtual reality of the mind". That was for a conference whose participants had a strong background in AI and neuroscience. So I started with those two subjects and presented Peirce's semiotic as the unifying framework for organizing and relating research in those two fields. Before getting to Peirce, I started with terminology and examples that the audience was familiar with. See http://www.jfsowa.com/talks/vrmind.pdf The full presentation is rather long (112 slides), but Just look at three slides to see the point: Slide 45 describes an experiment that shows how physics instruction changes neural representation. I describe the study briefly and include the URL of the full publication. Slide 46 shows three fMRI images of neural activity in the brain of the students. And it uses the same terminology as the original publication. (See a copy below.) Slide 57 shows exactly the same three images as slide 46, but it describes the neural activity in terms of Firstness, Secondness, and Thirdness. As far as I know, this is the first example that shows neural correlates of Peirce's three categories. If anyone knows of any other examples, I would love to see them.

Slide 57: Neural Correlates Neural correlates of Firstness, Secondness, and Thirdness: ● Perception is based on localized percepts or prototypes. It classifies phenomena by the monadic predicates of Firstness (fMRI image #1). ● Long-distance connections in the parietal lobes support dyadic relations that connect all sensory and motor modalities. They represent the structures of Secondness (image #2). ● The frontal lobes process the mediating Thirdness in reasoning, planning, causality, and intentionality (image #3). ● Much more detail must be analyzed and explained, but the examples in slides 45, 46, and this one illustrate promising directions to explore.
