Las 15 preguntas de un vistazo

¿Prefieres leer antes de jugar? Abajo están todas las preguntas de la muestra. Las respuestas y explicaciones quedan plegadas hasta que las abras.

1. 1. A technician splits a 10-minute observation into 30-second intervals. At the exact end of each interval, she looks up and records only whether the client is out of seat at that moment. Which procedure is she using?

   • A. Whole interval recording
   • B. Partial interval recording
   • C. Momentary time sampling
   • D. Permanent product recording
   Ver respuesta y explicación

   Respuesta: C. Momentary time sampling

   Momentary time sampling only looks at the instant each interval ends, so whatever happens in between is not recorded. Partial interval recording scores an interval if the behavior happens at any point in it, whole interval recording only if it lasts the entire interval, and permanent product recording measures what a behavior leaves behind, such as a finished worksheet.

2. 2. Which of these definitions describe behavior in observable and measurable terms?

   Marca todas las que correspondan.

   • A. Hits the table with an open hand hard enough to be heard across the room
   • B. Gets frustrated when asked to clean up
   • C. Says "no" or turns away within 5 seconds of an instruction
   • D. Is defiant during work time
   • E. Leaves the chair so that no part of the body touches the seat

   Respuesta: A. Hits the table with an open hand hard enough to be heard across the room, C. Says "no" or turns away within 5 seconds of an instruction, E. Leaves the chair so that no part of the body touches the seat

   A good definition describes what the person does, so that two observers would count the same events. Hitting the table, saying no or turning away, and leaving the chair can all be seen and counted. Frustrated and defiant are labels for an inner state or an attitude, and two people watching the same session would score them differently.

3. 3. Complete the sentence.

   Partial interval recording tends to _____ how much a behavior occurs, while whole interval recording tends to _____ it.

   Opciones para el hueco 1: overestimate, underestimate, measure exactly

   Opciones para el hueco 2: overestimate, underestimate, measure exactly

   Ver respuesta y explicación

   Respuesta: overestimate, underestimate

   In partial interval recording, a single brief occurrence marks the whole interval, so the result runs high. In whole interval recording, the behavior has to last the entire interval to be scored, so short episodes drop out and the result runs low. That is why partial interval suits behavior you want to reduce and whole interval suits behavior you want to see more of.

4. 4. A technician places five items in front of a client and lets the client take one. She then removes the chosen item and presents the remaining four again, and repeats until one item is left. Which preference assessment is this?

   • A. Paired stimulus
   • B. Multiple stimulus without replacement
   • C. Free operant
   • D. Single stimulus
   Ver respuesta y explicación

   Respuesta: B. Multiple stimulus without replacement

   In a multiple stimulus without replacement assessment, the chosen item is not put back, so the order of choices gives a ranking from most to least preferred. A paired stimulus assessment offers two items at a time, a free operant assessment watches how long the client engages with freely available items, and a single stimulus assessment offers one item at a time.

5. 5. During a functional analysis, what is the RBT's role?

   • A. Choosing which test conditions to run and in what order
   • B. Interpreting the graphs and deciding which function the behavior serves
   • C. Explaining the results to the family once the sessions are done
   • D. Running the conditions exactly as designed and recording the data
   Ver respuesta y explicación

   Respuesta: D. Running the conditions exactly as designed and recording the data

   The outline says an RBT participates in components of functional assessment. Designing the analysis, interpreting the results and explaining them to the family belong to the supervising behavior analyst. The RBT's part is to carry out the conditions as written and to collect accurate data, because a sloppy condition or a missed data point can point the whole team at the wrong function.

6. 6. Which sequence shows the parts of a discrete trial in the correct order?

   • A. Discriminative stimulus, response, consequence, intertrial interval
   • B. Response, discriminative stimulus, consequence, intertrial interval
   • C. Discriminative stimulus, consequence, response, intertrial interval
   • D. Intertrial interval, consequence, discriminative stimulus, response
   Ver respuesta y explicación

   Respuesta: A. Discriminative stimulus, response, consequence, intertrial interval

   A discrete trial starts with the instruction or cue, the discriminative stimulus, followed by the learner's response and then the consequence, such as reinforcement for a correct answer or a correction. A short pause, the intertrial interval, separates it from the next trial. When a prompt is needed, it comes right after the instruction and before the response.

7. 7. Complete the sentence.

   In _____ chaining, the learner is taught the last step of the task analysis first, while the technician completes all the earlier steps.

   Opciones para el hueco 1: forward, backward, total task

   Ver respuesta y explicación

   Respuesta: backward

   Backward chaining starts at the end, so the learner finishes the task and contacts the natural reinforcer of completing it on every trial. Steps are then added from the back toward the front. Forward chaining starts with the first step, and total task chaining teaches every step on every trial with whatever prompting each one needs.

8. 8. After giving an instruction, a technician waits a few seconds. If the learner does not respond, she gives a gesture, then a model, then physical guidance, stopping as soon as the learner responds. Which prompting procedure is this?

   • A. Most-to-least prompting
   • B. Least-to-most prompting
   • C. Stimulus fading
   • D. Constant time delay
   Ver respuesta y explicación

   Respuesta: B. Least-to-most prompting

   Least-to-most prompting gives the learner the chance to respond with as little help as possible, adding more support only when needed. Most-to-least runs the other way, starting with full help and fading it, which is the usual choice when errors should be kept low. Stimulus fading changes the material itself, and time delay changes the wait before a prompt.

9. 9. Which statements about a token economy are correct?

   Marca todas las que correspondan.

   • A. Tokens should be delivered right after the target behavior, not saved up for the end of the session
   • B. Tokens keep working without backup reinforcers once the client is used to earning them
   • C. Tokens are conditioned reinforcers that get their value from being exchanged for backup reinforcers
   • D. Backup reinforcers work best when the client already has free access to them all day
   • E. An RBT can change the exchange rate on the spot if the client seems bored
   Ver respuesta y explicación

   Respuesta: A. Tokens should be delivered right after the target behavior, not saved up for the end of the session, C. Tokens are conditioned reinforcers that get their value from being exchanged for backup reinforcers

   A token has no value of its own. It works because it can be exchanged for backup reinforcers, and it works best when it follows the behavior immediately. If the backup items are freely available anyway, there is no reason to earn tokens for them, and without any exchange the tokens soon lose their value. The exchange rate is part of the plan, so a change goes through the supervisor.

10. 10. A child screams whenever a math worksheet is put in front of him, and the worksheet is usually taken away until he calms down. What is the most likely function of the screaming?

    • A. Escape from the task
    • B. Access to attention
    • C. Access to a tangible item
    • D. Automatic reinforcement
    Ver respuesta y explicación

    Respuesta: A. Escape from the task

    The pattern to look for is what reliably follows the behavior. Here the worksheet goes away, so the screaming is most likely maintained by escape, a form of negative reinforcement. Attention would look like adults reacting, tangible would look like receiving an item, and automatic reinforcement would mean the behavior happens regardless of what anyone does.

11. 11. Complete the sentence.

    In _____, reinforcement is delivered at the end of a set interval only if the problem behavior has not occurred during it.

    Opciones para el hueco 1: DRA, DRO, DRI, DRL

    Ver respuesta y explicación

    Respuesta: DRO

    Differential reinforcement of other behavior, DRO, reinforces the absence of the problem behavior for a set time. DRA reinforces a specific alternative behavior, DRI a behavior that cannot happen at the same time as the problem behavior, and DRL a lower rate of a behavior that is fine in moderation.

12. 12. A behavior that used to get attention is now placed on extinction as part of the plan. Which of these might the technician see, especially early on?

    Marca todas las que correspondan.

    • A. A temporary increase in the behavior
    • B. New variations of the behavior
    • C. Emotional responses such as crying or anger
    • D. An immediate drop to zero on the first day
    • E. A permanent end to the behavior that can never return
    Ver respuesta y explicación

    Respuesta: A. A temporary increase in the behavior, B. New variations of the behavior, C. Emotional responses such as crying or anger

    When a behavior stops working, it often gets worse before it gets better. That temporary increase is the extinction burst, and it often comes with new forms of the behavior and emotional responding. A behavior that has faded can also come back later, through spontaneous recovery or resurgence, so neither an instant drop nor a permanent end is something to expect.

13. 13. Which session note is written most objectively?

    • A. Client was in a bad mood all morning and did not want to work on any of his programs today.
    • B. Client seemed tired and unfocused, probably because he went to bed late the night before.
    • C. Client completed 8 of 10 matching trials independently and cried for 2 minutes when the tablet was removed.
    • D. Client was manipulative during clean-up and kept testing limits with every adult in the room.
    Ver respuesta y explicación

    Respuesta: C. Client completed 8 of 10 matching trials independently and cried for 2 minutes when the tablet was removed.

    An objective note reports what happened in terms anyone could have observed: counts, durations and the events around them. Bad mood, tired because of bedtime, and manipulative are guesses about feelings, causes or intent. If something might affect progress, such as a late night or a new medication you were told about, you report it to your supervisor as information rather than writing it in as the explanation.

14. 14. A parent asks the RBT to stop using the visual timer in the behavior plan because it seems to upset the child. What should the RBT do?

    • A. Stop using the timer from now on, since the parent is the client's guardian and knows the child best
    • B. Tell the parent that a behavior plan can never be changed once it is written
    • C. Look up research on timers and suggest a different approach to the parent at the next session
    • D. Keep following the plan as written, thank the parent, and pass the concern to the supervisor promptly
    Ver respuesta y explicación

    Respuesta: D. Keep following the plan as written, thank the parent, and pass the concern to the supervisor promptly

    An RBT implements the plan and does not change it. The parent's concern matters and may well lead to a change, but deciding that belongs to the supervisor, so the RBT passes it on in a timely manner. Dropping the timer alone, dismissing the parent, or giving a recommendation of your own all step outside the role.

15. 15. A client's parent offers to pay the RBT to babysit the client on weekends. What is the best response?

    • A. Accept, since babysitting happens outside work hours and is a private arrangement with the family
    • B. Decline or ask the supervisor first, since a second paid role with the family is a multiple relationship
    • C. Accept, but avoid running any ABA programs or taking data while babysitting
    • D. Accept, because the extra hours with the client will help skills generalize to the home
    Ver respuesta y explicación

    Respuesta: B. Decline or ask the supervisor first, since a second paid role with the family is a multiple relationship

    Being the client's technician and the family's paid babysitter at the same time is a multiple relationship. It can blur professional boundaries and make objective work harder, even with the best intentions. The outline asks RBTs to recognize these risks and how to handle them, which in practice means not starting the second role and talking to the supervisor.

Qué entra en el examen RBT en 2026

El examen de Registered Behavior Technician (técnico de conducta registrado) lo fija la Behavior Analyst Certification Board (BACB) y se hace en persona en un centro de examen de Pearson VUE. Según el RBT Handbook, tiene 85 preguntas, de las que 75 puntúan y 10 son preguntas piloto que no puntúan y que no puedes distinguir del resto. Todas son de opción múltiple con cuatro opciones y una sola respuesta correcta, y tienes 90 minutos. Tu resultado depende de tu rendimiento global, no de aprobar cada área por separado.

Desde 2026 el examen sigue el RBT Test Content Outline (3.ª ed.), que algunas webs de preparación llaman Task List 3.0. Tiene 43 tareas en seis dominios, y las 75 preguntas que puntúan se reparten así: Data Collection and Graphing (recogida de datos y gráficas) 13, Behavior Assessment (evaluación de la conducta) 8, Behavior Acquisition (adquisición de conductas) 19, Behavior Reduction (reducción de conductas) 14, Documentation and Reporting (documentación e informes) 10 y Ethics (ética) 11. La adquisición de conductas es el bloque más grande, así que los procedimientos de enseñanza como los ensayos discretos, las ayudas (prompting), el encadenamiento y el refuerzo merecen la mayor parte de tu tiempo de estudio.

El examen es solo un paso de varios. Antes de presentarte, la BACB espera que tengas al menos 18 años, que hayas terminado el bachillerato (high school), que pases las comprobaciones de antecedentes y de registros de abuso, que completes una formación de 40 horas y que superes una Initial Competency Assessment (evaluación inicial de competencias). Cuando apruebas, trabajas bajo supervisión continua y te recertificas en un ciclo que fija la BACB, que en 2026 pasó de un año a dos. Estas normas ya han cambiado antes y pueden volver a cambiar, así que toma los datos vigentes, incluidos plazos y tasas, del RBT Handbook en bacb.com y no de una página de preparación, esta incluida.

Cómo usar esta muestra

Estas 15 preguntas siguen en pequeño los pesos del esquema: 3 de recogida de datos y gráficas, 2 de evaluación de la conducta, 4 de adquisición de conductas, 3 de reducción de conductas, 1 de documentación e informes y 2 de ética. La mayoría son escenas cortas de una sesión, porque así pregunta el examen real: no qué significa un término, sino qué procedimiento está aplicando un técnico y qué debería hacer a continuación.

El examen real solo usa preguntas de una respuesta con cuatro opciones. Esta muestra también usa marcar todas las que correspondan y completar huecos, que son más difíciles a propósito, porque no puedes acertarlas descartando tres respuestas incorrectas. Hazla de una sentada y sin apuntes, y después lee todas las explicaciones, también las de las preguntas que acertaste. Trata una respuesta fallada como un tema y no como un dato. Si fallaste la pregunta del registro por intervalo parcial, repasa juntos todos los procedimientos de medición, porque al examen le encanta ponerlos uno al lado del otro.

Una cosa que hay que dejar clara. Esto es práctica de examen, no orientación clínica. Las preguntas de ética de aquí tratan de los límites del rol de RBT, como quién cambia un plan y a quién le planteas una preocupación. Con un cliente real, sigues el plan de conducta que escribió tu supervisor y le preguntas a tu supervisor, no a una página de preguntas.

Cómo StudyPDF crea tests completos con tu propio material

Quince preguntas pueden enseñarte dónde flojeas. Por sí solas no te dejan listo para el examen, y un banco genérico rara vez coincide con lo que de verdad subrayó tu formación de 40 horas.

StudyPDF parte de tu material. Subes las diapositivas de tu formación, tus apuntes del curso o los documentos que te dio tu supervisor, y Bo, el agente de estudio, crea tests de práctica completos con esas páginas exactas. Cada pregunta sale de tu material y cada explicación cita de dónde viene la respuesta, así que puedes ir directo a la fuente cuando algo no te cuadre. Puedes generar tests nuevos tantas veces como quieras, centrarlos en un dominio como la medición o la reducción de conductas, y seguir qué conceptos sigues fallando.

No hace falta subir nada para empezar. Si no tienes ningún archivo a mano, nombra un tema, por ejemplo las ayudas y su retirada gradual o los procedimientos de medición, y Bo escribe un test de práctica sobre eso. Empezar es gratis.
