A Motivating Operation (MO) is anything that:

  1. Changes how much your child wants something (makes it more or less valuable), and
  2. Changes behavior (makes a behavior more or less likely to happen to get that thing)

Why it matters

  • Prevents problem behavior before it starts
  • Makes learning easier and more successful
  • Responding more effectively in the moment

For example: if your child hasn’t eaten in a while, food becomes more valuable — they’re more likely to ask, grab, or get upset to get food. Hunger is an MO.

Everyday examples

  • Sleep deprivation — attention or comfort becomes more valuable, so you see more whining and clinginess
  • Too much screen time already — screens lose value, so there is less motivation to earn them
  • Being told “no” often — attention may become more valuable, so there are more attempts to get a reaction

How to “establish” helpful MOs

You’re not creating motivation out of nowhere — you’re arranging the environment so your child wants to communicate or behave appropriately.

  1. Make access controlled (but fair) — keep preferred items visible but not freely available. A toy on a shelf means your child is more likely to request it.
  2. Use small portions — give a little at a time. A few crackers instead of the whole bag means more chances to ask appropriately.
  3. Rotate toys and activities — novelty increases motivation. Put toys away and reintroduce them later so they feel “new” again.
  4. Build in opportunities to ask for help — a closed container means your child needs help, which creates a communication opportunity.
  5. Limit (not remove) constant access — if something is always available, it loses value. Balance is key; avoid frustration overload.

One caution

Don’t overuse MOs in a way that creates distress (e.g., extreme deprivation). The goal is to encourage communication and positive behavior, not frustration.
