.I'm pretty sure you and I use "positive" and "negative" in regards to behavior change differently. But just to be sure, what do you mean by positive and negative?
I am using it in the *colloquial* version of operant conditioning, rather than the technical one, because most of the audience does not know the technical terms, and the technical terms run outright contrary to colloquial language. Most folks will get confused by "positive punishment".
We refer to that as multiple schedules.
I don't know who "we" are. Do you wish to make an appeal to authority at this time?
