Could the two of you, and we'll obviously unpack this in a lot of different ways, but can the two of you just provide a general overview of what this mediational theory is and how, I guess, initially you applied it to those equivalence relations as a starting point?

Yeah, well, the...

The overall approach here is, I can give you a little bit of history.

Both of us have taught stimulus equivalence and other kinds of topics.

And we also published a couple of papers back in the 80s about function altering.

And we talked about function altering specifically about verbal stimuli, call them rules.

We did not talk about a mechanism.

So are the mediating behaviors always like a code base or are there other examples of mediating behaviors that would be applicable?
