Yes! And it's not just "addressing" those contingencies, but all respecting the necesity of them without be judgmental. It's one thing to point out that giving the screaming toddler the toy may reinforce the screaming and be counterproductive to our functional communication training, DRA, DRO, etc. It's much more complicated to create a more nuanced intervention that accounts for the fact that, sometimes, mom just needs to do whatever it takes to get that todddler to stop crying (or not even cry to begin with), and this all has to be addressed first and foremost at the MO level. All too often, clinicians do the first part- the pointing out the inadvertent reinforcment- without being caring or kind enough (and, let's face it, skilled enough) to recognize the need of the mom to not only be the contingency manager for the toddler in question, but also the head chef, waiter, and dishwasher for the rest of the family, doing so between shifts as CNA, all while studying to get their nursing degree. IMHO, only a real jerk says "yeah, but if you don't stop giving them the toy when they scream then they won't stop screaming" and leaves it at that. That only leads to a plan that CAN'T be followed (not "won't" be followed, as if the mom had a choice in the matter) and blaming the mother for "lack of follow-through" or some such nonsense.
Hint, Hint for those of you playing armchair behavior analyst at home- first question you should ask is "why can't he have free access to that toy, either all the time or- especially- at times when you need to be doing other stuff and can't spend more time teaching him how to ask for it without screaming." You'd be suprised how often you don't get a reall good answer to this. Also, it doesn't hurt to ask the toddler why they scream like that at mommy. Worst case scenario they don't give you an answer and you've lost the 7.346732 seconds it took to ask the question. In my book, toddlerhood (~2+ year old) is plenty old enough to be introducing the concept of agency over one's own behavior and collaboration with others. I rarely (maybe once every 100 or so clients) get any answere, let alone one that is related to the question, but I still ask.
BTW- I know you know all of this stuff,
@futureapppsy2 sy2. It's just a topic that is rather dear to me (and, as
@cara susanna susana pointed out) makes me seem like I know what I am doing when I talk aobut it.
