Abolishing operation

An abolishing operation has two related effects

The value-altering effect is a decrease in the current effectiveness of some consequence. The behavior-altering effect is a decrease or change in behavior that has historically produced, removed, or interacted with that consequence.

These effects are linked to a consequence class. Saying “motivation went down” leaves the analyst asking: motivation for what outcome, under which conditions, and shown by which behavior?

Satiation is a familiar example

After someone eats a large lunch, an offered snack may function as a weaker reinforcer for a food request than it did before lunch. The same lunch may have little effect on the value of conversation, music, or a quiet room.

One declined snack does not prove an abolishing operation. Preference, illness, sensory features, availability, history, and other simultaneous changes can also affect responding. Repeated observations or a suitable comparison strengthen the interpretation.

Relief can also lose current value

When an aversive condition ends, further escape from that condition has little current value because the condition is absent. The relevant responses may temporarily decrease. The conceptual literature on motivating operations and negative reinforcement contains important disagreements, so analysts should describe the exact antecedent condition, stimulus change, history, and response.

Edwards and colleagues review motivating operations and negative reinforcement, including the distinction between establishing operations that increase effectiveness and abolishing operations that decrease it. Their paper also critiques parts of conventional MO theory.

Establishing operations move in the other direction

An establishing operation temporarily increases the effectiveness of a consequence and evokes or increases behavior historically related to it. An abolishing operation decreases effectiveness and abates or changes related behavior.

The same event can have different effects for different consequences or people. Time without music may increase the value of listening for one person, while a noisy day may reduce it for another.

An AO and an SD answer different questions

A discriminative stimulus, or SD, signals that a response has produced reinforcement more often in its presence than in relevant comparison conditions. A motivating operation changes how effective that consequence currently is and alters related behavior.

A vending machine’s “in service” light may signal availability. A large meal may reduce the value of food from the machine. Availability and current value can vary independently, and both can influence responding.

The term describes a relation, not an inner state

The BACB BCBA Test Content Outline, 6th edition includes motivating operations, discriminative stimuli, reinforcement, and functional relations. It is examination content, not a clinical interpretation for any person.

Sundberg summarizes the MO concept’s value-altering and behavior-altering effects and the establishing-operation and abolishing-operation distinction. These concepts organize observable environmental relations rather than diagnose a person as “unmotivated.”

Clinical use has ethical limits

A treatment plan should never manufacture deprivation of food, water, bathroom access, sleep, communication, mobility, prescribed care, relationships, or emergency help. Basic needs and health come first.

For covered behavior analysts, the current BACB Ethics Code addresses competence, client involvement, consent and assent when applicable, medical needs, assessment, risk, data, and continual evaluation. A qualified clinician interprets motivating operations within assessment and scope.

A fictional observation

Nadia chooses between crackers and a drawing activity during ten matched choice opportunities before lunch and ten after lunch. Crackers are selected in 7 of 10 before-lunch opportunities and 2 of 10 after-lunch opportunities. Drawing remains available in both periods.

The pattern is consistent with lunch functioning as an abolishing operation for crackers. It does not establish causation: time of day, cracker quality, routine, or other changes may contribute. The team preserves raw choices, opportunity definitions, food access, health context, and Nadia’s report.

Measure the claimed relation

Define the operation, consequence, historically relevant response, comparison periods, opportunities, and observation window. Report response allocation, rate, latency, or another measure that fits the behavior.

Keep preference assessment, reinforcer function, availability, and motivating-operation effects conceptually separate. A preferred item may have little reinforcing value in a particular moment.

Language should remain provisional. Say that an event “may have functioned as an abolishing operation for access to music during this period” when the evidence supports only a hypothesis. This identifies the consequence, time, and uncertainty. Avoid treating an AO as a permanent property of a person or item. Reassess when health, setting, access, deprivation history, choice options, or the consequence itself changes.
