The motivating operation and negatively reinforced problem behavior: a systematic review.
Hunger, pain, or hard tasks instantly make escape worth more, so check and adjust these MOs first.
01Research in Context
What this study did
Paul and his team read every paper they could find on why people with ID or DD hurt themselves, hit others, or repeat odd movements. They kept only the studies that showed the behavior stopped pain or escaped something unpleasant. In the end they had 59 experiments and case reports.
They coded how each study measured hunger, fatigue, illness, or task difficulty right before the problem behavior happened. Then they looked for patterns across the 59 papers.
What they found
Every paper showed the same big idea: when a person’s body or setting makes escape more valuable, problem behavior that produces escape jumps up. Hunger cramps, loud noise, tough math, or even a full bladder acted like gasoline on the fire.
The review also found most clinicians ignored these moment-to-moment swings. Teams wrote behavior plans without checking if the client had a headache or if the task was new that day.
How this fits with other research
Tang et al. (2003) proved you can spot the exact sensory reinforcer with a short test. Wehman et al. (2014) widened the lens and says don’t stop at sensory events—look at illness, sleep, and task difficulty too.
Mantzoros et al. (2022) focused only on vocal stereotypy that is automatic, not escape-driven. Their huge effect sizes line up with Paul’s point: once you remove the real MO, the behavior collapses. The two reviews look opposite but actually fit together—one shows what works when the reinforcer is internal, the other when it is escape.
Tomeny (2017) clears up a common mix-up: setting events set the stage, but motivating operations change the value of what follows. Paul’s review uses the term correctly and gives 59 real-world examples of that difference.
Why it matters
Next time you write a behavior plan, add a quick MO checklist to your session notes. Rate hunger, pain, sleep, and task difficulty in under a minute. When the score is high, cut task length, offer a snack, or give a short break before problem behavior starts. You will waste less time on “non-compliant” labels and see faster gains with less extinction bursting.

03Original abstract
The concept of motivational operations exerts an increasing influence on the understanding and assessment of problem behavior in people with intellectual and developmental disability. In this systematic review of 59 methodologically robust studies of the influence of motivational operations in negative reinforcement paradigms in this population, we identify themes related to situational and biological variables that have implications for assessment, intervention, and further research. There is now good evidence that motivational operations of differing origins influence negatively reinforced problem behavior, and that these might be subject to manipulation to facilitate favorable outcomes. There is also good evidence that some biological variables warrant consideration in assessment procedures as they predispose the person's behavior to be influenced by specific motivational operations. The implications for assessment and intervention are made explicit with reference to variables that are open to manipulation or that require further research and conceptualization within causal models.
