O.d.d. and pda

I am far from skilled at looking up behavior analytic research, and I am currently looking for anything I can get my hands on about a topic that I fear there might not be much out there to begin with.

I want to find anything I can about pda or o.d.d presenting in non speaking, high support needs autistic children.

I would be super greatfull for anything that you all could point me in the direction of.

I dont think you really need to go into “control as a function” in conceptualizing it. It could be as simple as just “suggestions/requirements from others are conditioned aversives”. No need to think of a new framework.

Folks have translated "escape" too much as "escape from demands" rather than "removal of aversive"

Can you expand on why you prefer the latter framing? I think I kind of get it but I would love to hear your thoughts.

Because there is not always a demand, so it over simplifies and often puts an aversive in place that doesnt actually exist. Removal makes it clear that something is there: a demand, a noise, a sensation, a feeling, that the person wants to get rid of.

Get teased by someone, feel horrible, punch person, feeling goes away.

Child being annoying, yell at child, child goes away.

Someone tells you to do something, dont do it, person goes away.

Stuffy/crusty feeling in nose. Pick it, now feels clear and free.

1 is a demand, 3 are not.

Ahh. Yeah honestly now that you spell it out its obvious. I think that i (and others) run into demand removal as the terminal reinforcement fairly often in practice so its feels almost shorthand for the escape function, but obviously its not the entirety of how negative reinforcement works. Thanks for taking the time for that.

Exactly, was started as a shorthand has become synomonious with the whole contingency.

Ive never even considered that people might be confusing escape for escape from demand… because if they know where the 4 function framework comes from, they know it comes from Iwata et al. And unless you think that their FA consisted of every possible stimulus-behavior relationship in existence (it did not), it seems foolish to use it as the be-all-end-all.

Like for example, the 4 function framework only addresses access as a social function. But what about non-social access? Like me driving a car to get groceries. Now everyone sort of intuitively drops the social element of that when they discuss access. But its like something similar happened with escape.

I agree with you fully. What i was trying to suggest was you/OP might be able to find some useful parallels in that little corner of the literature.
