A motivating operation (MO) is a change in the environment that alters how valuable a consequence is and how likely behavior that earns it becomes right now.
Example
A learner who has not eaten in hours is more likely to work for a snack. A learner who has just eaten a large snack is less likely to.
Key points
- An establishing operation increases the value of a reinforcer, such as being hungry.
- An abolishing operation decreases its value, such as being full.
- Deprivation and satiation are common examples.
Exam tip
If access to a reinforcer is limited before a session, the reinforcer is likely to be more effective. If the learner has had plenty, expect it to work less well.
Common mistake
Confusing an MO with an antecedent instruction. An MO changes how valuable a consequence is and how likely related behavior is right now.
Quick check
Does deprivation of a reinforcer usually increase its value? Yes, an establishing operation.
