Abative effect
A type of behavior-altering effect that causes an in-the-moment decrease in the current frequency of behavior that’s been reinforced by a specific stimulus.
B.16 Identify examples of motivating operations.
Abolishing operation
A type of motivating operation that is the product of satiation that, at that moment, decreases the effectiveness of the stimulus as a reinforcer as well as the current frequency
Behavior-altering effect
An effect of motivating operations that causes an in-the-moment increase or decrease in the current frequency of behavior that’s been reinforced by a specific stimulus.
Conditioned motivating operation (CMO)
An MO that, due to learning history, changes the value of other stimuli, objects, or events, and creates an in-the-moment change in the frequency of any behavior associated with those

Dana Do’s: How to Determine Value vs. Behavior Altering Effect
A motivating operation is not a thing that you hold in your hand. It is the state or condition of being deprived of something or satiated with something. PTB co-founder Dana Meller dives into the in-the-moment effects to help explain the difference.

Dana Do’s: How to Discriminate Between SDs & MOs
PTB co-founder Dana Meller breaks down the distinction between motivating operations (MOs) and discriminative stimulus (SDs).
Refer to BCBA® Task List (5th ed.) Sections B-10: Define and provide examples of stimulus control; and B-12: Define and provide examples of motivating operations.

Establishing operation
A type of motivating operation that is the product of deprivation that, at that moment, increases the effectiveness of the deprived stimulus as a reinforcer and increases the frequency of
Evocative effect
A type of behavior-altering effect that causes an in-the-moment increase in the current frequency of behavior that’s been reinforced by a specific stimulus.
Four-term contingency
A motivating operation is added to a three-term contingency and the added component of motivation has an abative or evocative effect on the behavior (e.g., MO-SD-Bx-C).

Function-altering effect
A phenomenon where the consequence of a behavior in the presence of an MO changes the behavior evoked by the specific or similar MOs in the future.
Motivating operation (MO)
An environmental variable that alters the reinforcing or punishing effectiveness of a stimulus and alters the current frequency of all behavior that has been reinforced or punished by that stimulus.
Reflexive MO (CMO-R)
A type of conditioned motivating operation that is established when a stimulus comes before and signals the onset of pain/something aversive, making it so that the removal of this warning
