UPDATE|GRADED A+
Question 1
While collecting data on your client, you separate the session into observation periods. At
the end of the observation period, you document whether or not the individual is
engaging in the behavior at that specific moment. What type of recording procedure is
being used, and how would you report the total at the end of the session?
A)Momentary time sampling/percentage
B)Momentary time sampling/frequency
C)Partial interval recording/frequency
D)Partial interval recording/percentage
CORRECT ANSWER
A)Momentary time sampling/percentage
Momentary time sampling procedures are typically reported as a percentage. (Cooper,
Heron, & Heward, 2019, p. 90)
Question 2
Melinda teaches 3rd graders. While her student teacher is leading the class, Melinda
checks on the children at the end of every 5-minute interval. Melinda does a count of all of
the children that are participating in the activity. Which measurement strategy is best
exemplified by this scenario?
A)PLACHECK
B)Momentary Time Sampling
1
,C)Partial-Interval Recording
D)Whole-Interval Recording
CORRECT ANSWER
A)PLACHECK
Planned Activity Check (PLACHECK) is a variation of momentary time sampling.
PLACHECK is utilized to measure the over all behavior of a group as opposed to one
individual. Partial-interval and Whole-Interval Recording require observation throughout
the session as opposed to checking on the individual(s) at the end of an interval (Cooper,
Heron, & Heward, 2019, p. 91).
Question 3
When reviewing a cumulative record, you notice that both sessions 7 and 8 are presented
at the same level across the ordinate. What can you assume?
A)The behavior did not occur in session 8
.B)The behavior occurred at the same rate in session 8 as in session 7.
C)Data error is likely.
D)The behavior occurred more often in session 8 than session 7.
CORRECT ANSWER
A)The behavior did not occur in session 8.
The Cumulative Record is constructed by adding the number of responses during each
session. If the level of the record is the same during session 8 as session 7 you can
assume that the behavior did not occur during session 8 (Cooper, Heron, & Heward,
2019, p. 134).
Question 4
2
,Which of the following may be a more accurate name of the procedure known as "NCR"?
A)Time-based delivery of appetitive stimuli
B)Noncontingent delivery of a preferred stimulus
C)Time-contingent delivery of reinforcement
D)Noncontingent delivery of appetitive stimuli
CORRECT ANSWER
A)Time-based delivery of appetitive stimuli
Noncontingent reinforcement may be more accurately called time-based delivery of
appetitive stimuli. Understanding the method of this intervention is clearly more
important than the name itself. Although the stimuli may be reinforcers in one setting,
the noncontingent delivery of such stimuli negate the effects of the stimuli, making them
more accurately named "appetitive" or "Preferred" stimuli. (Cooper, Heron, & Heward,
2019, p. 615)
Question 5
While at the library, Zach unknowingly pulls the fire alarm. The loud noise startles Zach,
and he is less likely to approach the fire alarm in the future. The fire alarm appears to have
functioned as a(n):
A)Unconditioned punisher
B)Conditioned punisher
C)Neutral Stimulus
D)Unconditioned reinforcer
CORRECT ANSWER
A)Unconditioned punisher
3
, Unconditioned punishers function as punishers even though the learner has no prior
learning history with the stimulus.
Question 6
To decrease the rate of the behavior, you must ________ the IRT.
A)Increase
B)Decrease
C)Maintain
D)Disperse
CORRECT ANSWER
A)Increase
To decrease the rate of the behavior, you must increase the Interresponse time (IRT).
(Cooper, Heron, & Heward, 2019, p. 85)
Question 7
A parent is concerned with their child who is refusing to complete daily living tasks such as
taking a bath and brushing her teeth. This was a recent change in behavior and the parent
took the child to the doctor to get her looked at. The doctor recommended addressing the
behavior with the assistance of the behavior analyst. What might be your next course of
action?
A)Define the target behavior(s)
.B)Refer them to a medical professional.
C)Conduct a functional assessment.
D)Create a unique rein
