100% Accurate Answers
1. What is the potential issue with Todd's estimate of vocal stereotypy when
using a multiple baseline design across settings?
No estimation can be made
Accurate estimation of behaviors
An overestimate of behaviors
An underestimate of behaviors
2. In a study examining the effects of a new intervention on student behavior,
how would you ensure that the response definition is clearly articulated in the
methodology section?
By providing specific criteria for what constitutes the target
behavior and including examples of acceptable responses.
By summarizing the intervention's goals without detailing the
behaviors.
By focusing solely on the statistical analysis methods used in the study.
By including a general overview of the research topic without
specifics.
3. The parents of a 4-year-old with ASD in your practice come in for a
consultation with concerns about their child's progress with speech therapy.
He makes few sounds and does not babble. He seems to understand what
they say and will follow some instructions. He can point to pictures they
label. He is the only child with ASD in his preschool program, and his speech
pathologist is focusing on sound imitation. His parents note he does not
imitate well. The parents are looking for guidance as to how his team might
promote communication. Of the following, what might you advise them to
, discuss with the Committee on Preschool Special Education regarding his
speech therapy?
Consider implementing a simple picture system, starting with choice
then building to picture exchange
Ordering a voice output tablet-based system as a first step for use at
home to complement the speech therapy at school
Plan to continue working on imitating sounds both with the therapist
and in front of a mirror
Continue reinforcing verbal imitation since visual systems prevent
learning spoken language
4. What is the term for the measurement system that records each correct
response in behavior analysis?
Interval recording
Permanent product
Time sampling
Frequency count
5. Describe how a frequency count measurement system is utilized in assessing
mastery of a task in applied behavior analysis.
A frequency count assesses the quality of responses given by a
learner.
A frequency count tracks the number of errors made during a task.
A frequency count records the duration of time spent on a task.
A frequency count measures the number of correct responses to
determine if a learner has mastered a task.
,6. Describe the difference between measures of central tendency and
measures of dispersion in statistics.
Measures of central tendency are used only in qualitative research,
while measures of dispersion are for quantitative research.
Measures of central tendency summarize data with a single value,
while measures of dispersion indicate the spread of data points.
Measures of central tendency are always higher than measures of
dispersion.
Measures of central tendency show how data varies, while measures
of dispersion provide an average.
7. Describe the significance of establishing a correlation in research within
applied behavior analysis.
Establishing a correlation eliminates the need for further research.
Establishing a correlation is only relevant in experimental designs.
Establishing a correlation helps researchers understand the
relationship between variables, which can inform future
interventions.
Establishing a correlation proves that one variable causes changes in
another.
8. Describe the difference between interpreting experimental control and
assessing basic effects in visual analysis.
Interpreting experimental control evaluates statistical significance,
while assessing basic effects examines data trends.
Interpreting experimental control is about data collection methods,
while assessing basic effects is about visual representation.
, Interpreting experimental control is concerned with sample size, while
assessing basic effects looks at the whole study.
Interpreting experimental control looks at the entire study's data,
while assessing basic effects focuses on adjacent phases.
9. Jacob recently conducted a study at a residential center in which they
evaluated a procedure to train direct care staff to increase positive
interactions with the residents during mealtime. During the course of the
study they became concerned that the data collectors began to depart from
the accurate use of definitions over time. Jacob is most likely concerned with
which of the following:
Observer drift
Poor reliability
Reactivity
Observer Bias
10. Dr. S uses changing criterion design to implement physical activity program
that is designed to incrementally increase physical activity in people with
ASD. Which is a guideline for using changing criterion?
Phase changes should be made only when there is stability in
current phase and a tx effect in preceding panel
All tx phase should include same # of data points to evaluate
stepwise changes in data
When behavior change is slow, phases should be longer to ensure
stability before the criterion is changed
Special effort should be made to minimize multiple treatment
interference
