Applied Behavior Analysis Motivating Operations
This set explains motivating operations in ABA, focusing on Establishing Operations (EOs), which change the effectiveness of a reinforcer and influence the frequency of behaviors, and describes the value-altering effect, which can increase (EO) or decrease (AO) reinforcement effectiveness.
Establishing Operation (EO)
any environment variable that:
(a) alters the effectiveness of some stimulus object or event as a reinforcer
(b) alters the current frequency of all BX that has been reinforcement by that stimulus, object or event

| Term | Definition |
|---|---|
Establishing Operation (EO) | any environment variable that: (a) alters the effectiveness of some stimulus object or event as a reinforcer |
value- altering effect | either an increase in the reinforcing effectiveness of some stimulus object or even in which case the MO is an EO or a decrease in reinforcing effectiveness in which the MO is an AO |
behavior- altering effect | Evocative effect: Abative effect: |
recovery from punishment procedure | the occurrence of response without its punisher |
unconditioned motivating operation (UMO) | food deprivation and painful stimulation |
reinforcer establishing effects | deprivation with respect to food water oxygent, activity and sleep have these effects |
reinforcer abolishing effect | food water ingenstion, oxygen intake, engaging in activity and sleeping |
conditioned motivating operations (CMO) | motivating variables that alter the reinforcing effectiveness of other stimuli, objects, or events but only as a result of learning history |
surrogate CMO CMO-S | accomplishes what the MO it was paired with accomplishes |
transitive CMO CMO-T | makes something else effective as reinfrocement |
reflexive COM CMO-R | alters a relation to itself (makes its own removal effective as reinfrocement) |
motivating operation MO | alters the effectiveness of some stimulus or a reinforcer, the value altering effect |
evocative effect | an increase in the current frequency of behavior that has been reinforced by the stimulus that is increased in reinforcing effectiveness by the same motivating operations. |
abative effect | a decrease in the current frequency of bx that has been reinforced by the stimulus that is increased in reinforcing effectiveness by the same motivating operation |
abolishing operation | a MO that decreases the reinforcing effectiveness of a stimulus, object, or event |
unpairing | any relationship developed by a pairing procedure can generally be weakened |
