Does teaching an omnibus mand preclude the development of specifying mands?
Teach one general mand first; it stops problem behavior and still lets kids learn specific words later.
01Research in Context
What this study did
Three preschoolers with autism were taught to say, “My way, please” when they wanted something.
The team first used this one-size-fits-all mand to stop problem behavior. Later they taught specific mands like “truck, please” and “cracker, please.”
Each child had six 10-minute play sessions per day. The researchers tracked how often the child used the mand and how often problem behavior happened.
What they found
All three kids learned the omnibus mand in 1–3 days. Problem behavior dropped to zero right away.
When the team later taught specific mands, every child learned those too. The earlier omnibus mand did not block new, precise words.
In fact, kids used the new specific mands more than the old general one once they were taught.
How this fits with other research
Zhang et al. (2023) showed that warm, positive parenting helps children with autism act more prosocial. Ward’s study adds that giving the child a quick, easy way to ask also helps the moment go smoothly.
Higgins et al. (2021) warned that stressed parents may over-rate problem behavior. Ward’s data give you a fast tool—an omnibus mand—to drop that behavior before you even ask parents to score it.
None of the neighbor papers tested mand training, so Ward’s finding is new: start broad, then go specific without fear of blocking later words.
Why it matters
You can teach “My way, please” on Monday and stop most hitting or crying by Wednesday. Later, add exact words like “train” or “juice” without re-building problem behavior. This two-step plan saves session time and keeps parents happy.

03Original abstract
When problem behavior is controlled by a synthesized reinforcement contingency, a simple omnibus mand that yields access to all reinforcers simultaneously has been shown to effectively replace problem behavior. The question arises as to whether teaching an omnibus mand will preclude the acquisition of specifying mands for each of the combined reinforcers. In this study, after 3 students diagnosed with autism acquired an omnibus mand ("My way, please") that yielded all identified reinforcers simultaneously, specifying mands (e.g., "All done," "May I have my toys?" "Play with me") were taught to yield each individual reinforcer (e.g., escape, tangibles, attention). Problem behavior was immediately eliminated for all children, and the omnibus mand was acquired quickly. Teaching an omnibus mand did not preclude acquisition of specifying mands for any learner and instead allowed for the acquisition of specifying mands once problem behavior had been effectively reduced.
