BCBA Mock Exam OBHS/ Well Graded
A+ Updated 2025
A - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals.
Select the most reasonable first step in the treatment process.
You wish to conduct some descriptive analyses. Which of the following is NOT a
rationale for such an activity?
a. To determine functional relations
b. To provide information that might lead to a functional relationship
c. To examine patterns of the behavior
d. To generate hypotheses about the behavior
B - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals.
Select the most reasonable first step in the treatment process.
At first, you are puzzled by the behavior. You therefore work with the child, and then let
the hypotheses evolve from your data. This example demonstrates the process of:
a. Induction
b. Deduction
c. Social learning theory
d. Stimulus equivalence
D - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals. To conduct your descriptive
analysis, you realize that someone should consent to the process. From whom should
you obtain consent?
a. The child
b. The parents
,c. The teachers
d. Both the child and the parents
B - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals. During some of your
interviews, the parents report that the behavior began about 2 years ago when the child
was afflicted with a serious intestinal bacterial infection. What should be your next step?
a. Include that fact in your analysis
b. Immediately ask for a medical exam that looks at the status of the infection
c. Conduct a functional analysis of the current reinforcers
d. Report the problem to child protective services
B - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals. One of the tools that you wish
to use is a pattern analysis. Which best exemplifies this method?
a. Have the parents record a narrative during the day so that you can examine the
behavior and the situations under which it occurs.
b. Have the parents record behaviors and the time that they occur during the day
c. Set up an ABC format sheet and have the parents record behavior
d. Allow the parents to tally the data frequencies and the antecedents they observed
C - CORRECT ANSWERS-You have been asked to consult on a case involving a 10
year old girl who engages in some severe SIB at home, such as scratching her head,
banging her head, and poking her eyes. She lives at home with her mother and father.
She is nonverbal, but will take her parents by the hand and show them things that she
wants. She seems to be able to perform many tasks, but the SIB definitely interferes
with many activities.
For example, she engages in high-rate SIB during meals. From your descriptive
analysis, you generate many kinds of information. You would like to have some rate
data across days. How might you do this?
a. Plot the number of occurrences of the behavior
b. Count the number of occurrences and plot them by the situation in which they
occurred
c. Count the number of occurrences and divide by the recording time each day
d. Count the number of occurrences and multiply it by the dependent variable
, B - CORRECT ANSWERS-The results of your descriptive analysis suggest that the SIB
occurs when the mother is not in close proximity to the child. Thus, she begins to injure
herself anytime the mother leaves her side. Data also show that in general, SIB is
followed by mother returning to the child.
You wish to do some systematic manipulations to confirm the hypothesis. Which of the
following best exemplifies this?
a. Collect and organize ABC data
b. Have mom remain close to the child. Then have her leave the child's side. Count SIB
when the child is close to mom and when mom is not close by.
c. Examine ABC data and look for SIB when mom is close by and when mom is not.
d. Examine SIB in and out of task.
B - CORRECT ANSWERS-A client under your supervision engages in frequent
rumination that appears to have resulted in substantial weight loss. What is the first
assessment task?
a. Systematic manipulation of some variable
b. Records review
c. Nothing - the behavior is not change worthy
d. Conduct an IQ test
C - CORRECT ANSWERS-You find that one of your clients has a substantial anxiety
reaction to being in the lunchroom. You posit that there is some kind of respondent
conditioning process that has caused this, and you wish to try respondent extinction.
This would involve
a. Social extinction - ignore the child when he becomes anxious
b. Escape extinction - do not let the child escape from the lunchroom
c. Have the child frequently enter the lunchroom without any "traumatic" events
occurring.
d. Have the child perform a task while in the lunchroom.
B - CORRECT ANSWERS-The philosophy of determinism, as applied to the analysis of
behavior, assumes that behavior is:
a. subject to random occurrences.
b. caused by some event or combination of events.
c. a cause of other events.
d. determined by the will of the person.
B - CORRECT ANSWERS-You take an initial baseline on "in seat" behavior. You then
implement a token economy in which in seat behavior is reinforced with tokens. Your
treatment team decides to demonstrate the efficacy of the token system, and
recommends an A-B-C-B reversal design. Which of the following is an example of such
a design?
a. In the 3rd phase, stop implementing the token system
b. In the 3rd phase, present tokens for out of seat behavior
c. Present the tokens for in seat behavior in another setting
d. Implement a schedule of less frequent tokens in phase 3
