BACB BCABA Online Questions & Answers

• Question 151:

  When a child is taught to perform a certain behavior in the presence of certain specific stimuli, and not in the presence of other stimuli, this procedure is calleD.

  A. discrete trial training.
  B. controlling stimulus training.
  C. conditioned stimulus learning.
  D. stimulus discrimination learning.
  D. stimulus discrimination learning.

• Question 152:

  Three boys with autism, ages 710 years old, served as participants in a study. During baseline, staff used response blocking when five instances of aggression or head-banging occurred within 10 seconds, until attempts ceased for 1 minute.

  During baseline and treatment, each occurrence of aggression and head- banging was recorded daily and converted to the number of responses per hour. Treatment comprised a differential reinforcement of incompatible behavior (DRI)

  schedule coupled with response blocking after every head-banging or aggression. The staff initially applied the treatment to head-banging, while continuing to take a baseline on aggression. After noting treatment effects on head-banging, the

  staff then applied the treatment to aggression.

  What is the independent variable?

  A. DRI schedule with instruction on the incompatible behavior
  B. DRI schedule and response blocking
  C. rate of the incompatible behavior
  D. number of head-bangs and aggressions per hour
  B. DRI schedule and response blocking

• Question 153:

  Which method is the BEST to use when presenting categorical data from a functional analysis?

  A. a bar graph
  B. anecdotal report
  C. scatter plot
  D. standard celeration chart
  A. a bar graph

• Question 154:

  A child diagnosed with autism engages in hand flapping almost continuously at home, day care and school. An intervention is devised to alleviate this challenging behavior. Which type of experimental design would be BEST?

  A. reversal
  B. multi-element
  C. withdrawal
  D. multiple baseline
  D. multiple baseline

• Question 155:

  Each response in a chain produces a stimulus change that serves as both a discriminative stimulus anD.

  A. a prompt.
  B. a limited hold.
  C. a conditioned reinforcer.
  D. an establishing operation.
  C. a conditioned reinforcer.

• Question 156:

  A behavior analyst responsible for the evaluation of a behavior change program has been unable to get others to collect data on the targeted behaviors. The others involved, including other service providers, are relying on personal anecdotes and questionnaires to evaluate the effectiveness of the program. The primary consumer reports satisfaction with the results so far. To evaluate the program, the behavior analyst should:

  A. check the reliability from the questionnaire's information.
  B. conduct formal interviews to supplement the available information.
  C. obtain data on the targeted behaviors.
  D. use available information only.
  C. obtain data on the targeted behaviors.

• Question 157:

  One of the basic requirements for staff training is that the:

  A. completion of training should be based on the demonstrated competency of the staff.
  B. skills should be measured only upon the completion of training.
  C. training should be accomplished by observation followed by a question-and-answer session.
  D. underlying competency-based principles should be taught.
  A. completion of training should be based on the demonstrated competency of the staff.

• Question 158:

  A behavior analyst has been consulting for a client who repeatedly pushes her knuckles into her eyes. After conducting a functional analysis, implementing a function-based intervention plan, and ensuring all staff were thoroughly trained on the intervention procedures, data indicate the client's behavior has increased over the last month. What consideration is MOST likely to have been overlooked prior to conducting the FA?

  A. The behavior may be a symptom of the client's disability.
  B. Staff may lack competence for carrying out the intervention.
  C. There may be a biological/medical variable affecting the client.
  D. The increase in the behavior should have been anticipated due to an extinction burst.
  C. There may be a biological/medical variable affecting the client.

• Question 159:

  What is the reinforcing consequence in "I itch, therefore I scratch?"

  A. automatic positive reinforcement
  B. automatic negative reinforcement
  C. proprioceptive positive reinforcement
  D. proprioceptive negative reinforcement
  B. automatic negative reinforcement

• Question 160:

  What could be done to clarify the differentiation in the frequency of aggression among the environments shown in this graph?

  A. Use an equal interval graph.
  B. Record data for an entire week.
  C. Include more environments along the horizontal axis.
  D. Change the vertical axis so that the range is zero to twenty.
  D. Change the vertical axis so that the range is zero to twenty.
