SOLUTIONS
Jasper counted that Felicity sneezed 8 times. Which dimensional quantity of behavior is measured -
✅✅✅CORRECT -frequency
Sophie engaged in 24 episodes of crying. The observation period was 6 hours. What was Sophie's rate of
crying? - ✅✅✅CORRECT -4 episodes/hour
Scottie start his homework 2 minutes after his mom asked him to start. It took him 15 minutes to
complete his math assignment, 28 minutes to complete his writing assignment, and 7 minutes to
complete his science assignment. In between math and writing, he used the restroom for 5 minutes.
What was the total duration of completing his homework? - ✅✅✅CORRECT -50 minutes, does not
include the 2 minutes it took to start and using the restroom for 5 minutes (15 + 28 + 7 = 50)
After the teacher says, "ok, class is out," a student continues to remain at his desk for 2 minutes before
he gets up and packs his bag. It takes him 2 minutes to gather his books, 3 minutes to put them in his
backpack, and 1 minute to walk back to his desk and take a seat. What is this student's latency of packing
relative to the announcement? - ✅✅✅CORRECT -2 minutes
Tommy's mom says he eats his food quickly: He takes 12 bites of food per minute. What would be the
estimated average IRT? - ✅✅✅CORRECT -5 seconds
Christina puts a toy in front of Judy on 15 different occasions. Judy approached the toy on 10 occasions
and just walked away on 3 occasions. What is the percent occurrence of Judy approaching the toy? -
✅✅✅CORRECT -67% (10 divided by 15)
Across 3 days, there was low IOA on data collected during a new procedure implemented with a student.
For the student's behavior measured by two observers, agreement was calculated at 40%, 50% and 45%
for each respective day. What could be a potential issue? - ✅✅✅CORRECT -The definition of the
target behavior is unclear
Trina reviewed a video recording of a student 3 times, and took data on the student's eye contact using a
stopwatch, each time she counted 17 seconds. The client actually engaged in 23 seconds of eye contact.
, The fact that these 2 numbers don't match is because Trina's measurement lacks - ✅✅✅CORRECT -
Accuracy (Reliable b/c she viewed the video recording 3 times, But it is not accurate)
Tommy's doctor suggested that he slow his pace of eating. Which continuous measurement procedure
should be used in order to monitor Tommy's behavior and implement an appropriate behavior plan to
help him take bites at a slower pace? - ✅✅✅CORRECT -IRT
Trudy often interjects loudly during instruction which disrupts the other 28 students in her classroom.
B/c the teacher can't collect data on this, a 1:1 aide was assigned to help Trudy. What's the best
discontinuous measurement procedure to train the aide to use? - ✅✅✅CORRECT -Partial interval
sampling o (Not event recording b/c it is not discontinuous measurement procedure. Not whole interval
procedure b/c underestimates behavior they want to decrease. Not momentary time sampling b/c can
underestimate data)
After completing a preference assessment, Stella has several possible reinforcers she'd like to use w/her
client/ If she wants to assess whether or not these stimuli function as reinforcers for the client by
allowing the client to choose to work for either one stimulus or another, what assessment procedure can
she use? - ✅✅✅CORRECT -Concurrent operant reinforcer assessment (This is talking about a
reinforcer assessment not a preference assessment b/c it mentions she completed a preference
assessment and that she wants to assess whether stimuli function as reinforcers)
Sally is taking data on how long it takes Carina to swim around the pool Which dimension of behavior is
Sally measuring? - ✅✅✅CORRECT -Duration
Samantha used a withdrawal design to evaluate the effectiveness of a treatment. The use of the
withdrawal design exemplifies which dimension of ABA? - ✅✅✅CORRECT -Analytic is correct b/c it
seeks to identify a functional relation between IV and DV (Not conceptually systematic b/c this refers to
the extent by which behavior can be explained by basic principles. Not determinism b/c this refers to
universe being lawful place. Not empiricism b/c this refers to objective observation and subjective
interpretation of phenomena)
The discussion section of a journal article about teaching children to tact their own private events
suggests that these skills could be taught w/operant conditioning. Of the following, which is the most
appropriate analysis of this interpretation in the discussion section? - ✅✅✅CORRECT -This
interpretation in the discussion section seems consistent w/radical behaviorism
