Assess Multiple- and Mixed-Schedule Components

To assess multiple and mixed schedule components, define Keiko's component schedules, durations, transitions, response, consequence, exposure, and access. A multiple schedule correlates components with distinct signals; a mixed schedule omits those signals. Measure component-specific responding, consequence delivery, signal contact, transition effects, prompts, and direct experience. Signal presentation alone cannot establish discriminative control or schedule understanding.

Define every component

Write the response, consequence, schedule, duration, entry, exit, and transition rule for each component. Preserve actual context changes that co-occur with the schedule.

Specify signals or their absence

For multiple schedules, define accessible component-correlated stimuli. For mixed schedules, document that no distinct component signal is programmed while other contextual cues remain possible.

Verify signal contact

Check that Keiko can detect, distinguish, understand, and use each signal without forced gaze. Include text, icon, speech, AAC, tactile, or environmental forms as needed.

Measure by component

Report eligible responses, prompts, consequence deliveries, misses, errors, and direct experience separately for each component. Record transition and carryover periods.

Preserve the control question

Differential responding can support a signal-control hypothesis when paired with history and comparison. It does not establish comprehension, preference, or benefit by itself.

Use this sequence to assess multiple and mixed schedule components

Define Keiko's components and signals, verify access, measure component-specific response and delivery, preserve transitions and errors, ask about experience, and interpret differentiation within the sampled schedule.

Build Keiko's multiple-and-mixed component matrix

Create one versioned multiple-and-mixed component matrix for the school-club conversation review. Include Keiko's priority, response, consequence, programmed schedule, obtained schedule, count or clock, distribution, reset, signal, value, availability, delay, magnitude, quality, effort, prompts, access, health, exposure, integrity, agreement, raw sequence, invalidity, missed delivery, extra delivery, withdrawal, direct experience, benefits, side effects, result, uncertainty, decision, owner, correction, and review trigger. Store only decision-relevant information with role-limited access.

Validate Keiko's schedule evidence

Reproduce Keiko's 13/15 and 12/15 signal-contact results, 10/15 and 3/15 request results, and 9/10 and 1/3 partner-delivery results. Audit component duration, sequence, transitions, signals, visibility, language, AAC, prompts, consequence availability, and carryover. Compare with an unsignaled arrangement only if that question matters and the burden is justified. Ask Keiko whether signals are clear, useful, and respectful.

Keep Keiko's implementation, outcomes, and experience separate

Measure programmed-versus-obtained schedule integrity with due events. Measure Keiko's response and client-priority outcome with their own units. Ask separately about clarity, effort, comfort, usefulness, burden, and whether assessment should continue. Accurate implementation can coexist with poor fit or unwanted effects. Better experience can also occur without evidence that the schedule caused an outcome change.

Work through Keiko's example

Keiko has 15 signaled-available and 15 signaled-unavailable conversation periods. She contacts the correct signal in 13/15 and 12/15 periods. Her accessible conversation request occurs in 10/15 available and 3/15 unavailable periods. Partners respond as programmed after 9/10 available requests and mistakenly after 1/3 unavailable requests. Report signal contact, requests, and partner delivery with separate denominators. Preserve every planned and valid unit, raw count, denominator, eligible response, due event, count or clock, reset, signal, delivery, delay, miss, substitution, extra, access state, integrity result, withdrawal, direct report, system failure, correction, and unresolved item. This fictional example demonstrates one assessment control. It offers no universal schedule effect, behavioral function, diagnosis, trait, treatment effect, legal conclusion, coverage decision, payment promise, or outcome guarantee.

Address Keiko's main assessment risk

Pooling 13/30 requests hides component differentiation and partner errors. Calling the colors controlling cues without a relevant delivery history and comparison also overstates the evidence. Review response and consequence definitions, programmed and obtained rules, count or clock, reset, signal, value, availability, delay, effort, prompts, access, health, context, client experience, authority, and causal scope separately. High integrity cannot repair an inaccessible, burdensome, or ethically unsound schedule.

Keep schedule concepts and authority clear for Keiko

The ABAI Basic Principles page lists reinforcement schedules in higher-education content. The BACB Test Content Outline covers continuous and intermittent reinforcement, ratio and interval schedules, time schedules, compound schedules, maintenance, and schedule thinning as examination content. The current BACB Ethics Code addresses competence, involvement, consent and assent when applicable, positive reinforcement, medical needs, risk, data, documentation, and evaluation for covered people. These sources do not create an individualized schedule for Keiko.

Interpret ratio and interval patterns cautiously for Keiko

Baum analyzes interval and ratio performance from a molar perspective. Staddon and Cerutti review operant conditioning and schedule research. These sources support careful attention to programmed relations, obtained outcomes, time, and response allocation. Textbook schedule patterns are common findings rather than promised signatures for Keiko.

Measure ratio pauses without assigning character for Keiko

Lattal and colleagues review decades of research on pausing under ratio schedules. Pauses can vary with upcoming and prior ratios, reinforcer conditions, histories, and procedures. For Keiko, define the pause boundary, requirement, consequence, effort, and context before interpreting the observation. A pause is not proof of unwillingness or one mechanism.

Scope schedule-thinning evidence carefully for Keiko

Hagopian, Boelter, and Jarmolowicz reviewed schedule thinning following functional communication training and found 19 of 76 reviewed FCT studies described thinning. Falligant and colleagues provide an updated review addressing recurrence, pacing, reinforcer dimensions, competing activities, signals, and other design variables. These FCT-focused reviews do not create a universal schedule, delay ladder, or clinical result for Keiko.

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

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 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 Keiko.

Choose Keiko's next bounded action

Keiko chooses words and icons in addition to color and asks partners to explain transitions before using the schedule in another club setting. 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 responses, consequences, people, systems, schedules, or preferences change. A new arrangement creates a dated version rather than an error in Keiko's earlier performance.

Close Keiko's schedule review

Review the multiple-and-mixed component matrix with Keiko, the qualified behavior analyst, relevant partners, access owners, and specialists named in the manifest. Confirm that programmed and obtained schedules stay separate, due-event and response denominators are reproducible, AAC and basic access remain protected, health questions stay with qualified professionals, and conclusions remain bounded to the sampled response, consequence, schedule, time, and context. Keep this page draft and noindex until every required review is complete.
