To assess value-altering and behavior-altering effects, define Marisol's candidate operation and one consequence. Measure current consequence value through a suitable choice, allocation, or reinforcer test and measure behavior that has historically produced that consequence. Use comparable periods, clear timing, intact access, and raw denominators. Strong motivating-operation evidence requires both linked effects; partial or discordant results should remain visible.

Define the value-altering effect

Name the consequence and the direction of predicted change. Select a value measure that can detect relative choice, allocation, latency, work, or reinforcer effect while preserving voluntary access and client preference.

Define the behavior-altering effect

Choose one response class with a documented history of producing that consequence. Specify opportunities, windows, prompts, effort, omissions, invalidity, and whether multiple communication forms belong in the class.

Align operation and time

Record when the candidate operation occurs, its intensity or amount when measurable, time since exposure, and the observation window. Effects may fade, reverse, or vary by consequence.

Build comparable periods

Match consequence availability, activity, setting, partner, device state, response effort, prompts, and competing options. Use natural variation when manipulation would add burden or ethical risk.

Interpret discordant results

A value measure may change while the response stays stable, or the response may change while the value measure does not. Report the split pattern and investigate availability, history, measurement sensitivity, rules, effort, and context.

Use this sequence to assess value-altering and behavior-altering effects

Define Marisol's operation and consequence, select one value and one related-behavior measure, align timing, compare matched periods, show both results, and keep the MO conclusion as narrow as the linked evidence.

Build Marisol's linked-effects assessment sheet

Create one versioned linked-effects assessment sheet for the home music-choice routine. Include Marisol's priority, candidate operation, consequence, historically related response, learning history, value measure, behavior measure, comparison, timing, setting, partner, access history, consequence availability, effort, prompts, competing options, health, integrity, raw data, invalidity, missingness, withdrawal, direct experience, result, uncertainty, decision, owner, correction, and review trigger. Store only decision-relevant information with role-limited access.

Validate Marisol's motivating-operation evidence

Confirm that Marisol can access every option and response mode, each music choice produces the defined outcome, and request opportunities are truly comparable. Reproduce 9/12, 4/12, 8/12, and 3/12 from raw events. Review carryover, song familiarity, device state, partner behavior, time, and competing activities. Treat consistent change across both measures as stronger evidence while retaining alternative explanations and Marisol's direct report.

Keep Marisol's value, behavior, and experience separate

Measure current consequence value and historically related behavior with their own eligible units, then ask Marisol separately about clarity, effort, comfort, usefulness, burden, and whether assessment should continue. A value change can occur without the measured response changing. A response can change because of availability, prompts, effort, rules, or stimulus control. Direct experience remains important while answering a different question.

Work through Marisol's example

Marisol has 12 matched music-choice opportunities after a quiet interval and 12 after an hour of preferred music. She chooses music in 9/12 quiet-interval opportunities and 4/12 recent-music opportunities. Music requests occur in 8/12 and 3/12 corresponding routine opportunities. The aligned choice and request differences support a possible abolishing effect of recent music access in this sample, with time, activity, and song-set differences still open. Preserve every planned and valid unit, raw count, denominator, operation state, access history, consequence state, response, prompt, availability check, health context, integrity result, withdrawal, direct report, system failure, correction, and unresolved item. This fictional example demonstrates one assessment control. It offers no universal consequence value, diagnosis, trait, treatment effect, legal conclusion, coverage decision, payment promise, or outcome guarantee.

Address Marisol's main assessment risk

Using request rate alone as a value measure can confuse consequence availability, prompts, communication effort, or a changed task. Using choice alone leaves the behavior-altering part of the claim untested. Review operation definition, consequence specificity, response history, comparison, timing, health, access, availability, effort, prompts, context, client experience, authority, and causal scope separately. A large difference cannot repair an inaccessible or ethically unsound assessment.

Keep motivating-operation concepts and authority clear for Marisol

The ABAI Basic Principles page lists motivating operations in higher-education content. The BACB Test Content Outline covers motivating operations, discriminative stimuli, reinforcement, verbal behavior, assessment, and intervention as examination content. The current BACB Ethics Code addresses competence, involvement, consent and assent when applicable, medical needs, assessment, risk, data, documentation, and evaluation for covered people. These sources do not create licensure, payer approval, or an individualized plan for Marisol.

Use conventional MO terms precisely for Marisol

Sundberg summarizes the motivating-operation concept, including value-altering and behavior-altering effects and the establishing-operation and abolishing-operation directions. For Marisol, define the operation, consequence, relevant behavior, history, timing, and comparison directly. Deprivation, satiation, preference, availability, and response rate are related observations rather than interchangeable labels.

Preserve conceptual uncertainty for Marisol

Langthorne and McGill present surrogate, reflexive, and transitive conditioned motivating operations. Edwards and colleagues emphasize interaction between motivating operations and discriminative stimuli and question overreliance on subtype labels. Use these sources to frame hypotheses for Marisol, while observable operations and outcomes carry the report.

Handle negative-reinforcement interpretations carefully for Marisol

Edwards and colleagues review motivating operations and negative reinforcement and critique parts of conventional theory. The paper supports precise descriptions of antecedent conditions, consequence changes, response histories, and competing interpretations. It supplies no authority to create distress, block escape, remove essential support, or continue after Marisol withdraws.

Preserve treatment scope, AAC, assent, and access for Marisol

The CASP public summary supplies high-level ABA behavioral-health-treatment scope for autistic people, with licensed detail outside this page. ASHA's AAC portal says AAC users should always have access to their communication tools or devices. Breaux and Smith provide assent-focused practice guidance in an evolving evidence base. Follow governing sources and keep health care, food, water, bathroom access, communication, mobility, rest, relationships, safety, and emergency help available to Marisol.

Choose Marisol's next bounded action

Marisol selects the song set and asks the team to use her comfort rating alongside choice and request measures. Record the qualified owner, supporting evidence, effective date, current supports, health and access state, implementation check, accessible explanation, disagreement route, and reassessment trigger. Preserve the original assessment when consequences, routines, health, or preferences change. A new context creates a dated version rather than an error in Marisol's earlier response.

Close Marisol's motivating-operation review

Review the linked-effects assessment sheet with Marisol, the qualified behavior analyst, relevant partners, access owners, and specialists named in the manifest. Confirm that consequence value stays separate from differential availability, both linked effects have reproducible denominators, AAC and basic access remain protected, health questions stay with qualified professionals, and conclusions remain bounded to the sampled consequence, response, time, and context. Keep this page draft and noindex until every required review is complete.
