1. Josh, a BCBA, recently designed an intervention to decrease the problem behavior of one of his clients. Josh has learned that his client is inconsistent when taking his prescribed medication and Josh is worried that this inconsistency with medication may be effecting the behavior, making it difficult to determine whether his intervention is responsible for any changes in the behavior. Which of the following is Josh’s concern likely related to?
a. internal validity
b. external validity
c. social validity
d. face validity
2. On a line graph, the value of the dependent variable is displayed on the ________________.
a. condition line
b. abscissa
c. legend
d. ordinate
3. When using a MBL (multiple baseline?) across settings, the researcher:
a. adds an intervention across different behaviors and individuals in the same location
b. adds an intervention on the same behavior and subject across different settings or conditions
c. changes an intervention with different behaviors across different locations
d. adds and then removes an independent variable across different children in the same classroom
4. Data from direct observation is graphed across multiple conditions and the rate of the behavior across these different conditions is compared to determine which condition is related to the behavior.
Which of the following dimensions does this statement exemplify?
a. effective
b. technological
c. applied
d. analytic
5. Measurement has validity when it:
a. produces an observed value that matches the natural occurrence of the behavior
b. is collected using discontinuous measurement
c. results in data that directly measures what it sets out to measure
d. yields data that is consistent in repeated opportunities to measure
6. Nyla, an inclusion specialist, is using a new reading program to increase the word reading skills with 3 of her students. To experimentally assess the effectiveness of this program, which of the following designs would be most appropriate?
a. Cumulative Record
b. Multiple Baseline
c. Delayed Baseline
d. Reversal Design
7. Review the graph below:
Which of the following is accurate?
a. replication occurred within second baseline condition
b. predication occurred within second baseline condition
c. prediction occurred within initial baseline condition
d. replication occurred, verification did not
8. On an equal interval graph, _______________ the distance on the vertical axis between each unit of measurement magnifies the variability in the data, whereas ______________ the units of measurement on the vertical axis minimizes the portrayal of variability in the data set.
a. contracting-increasing
b. increasing-expanding
c. increasing-contracting
d. contracting-decreasing
9. Which of the following is an example of a behavior for which a reversal design would be appropriate to use?
a. disruptive verbal behavior
b. spelling errors
c. dangerous aggressive behavior
d. serious self-injury
10. Jason is a 5 yr old student who is not always on task during “centers”, a whole class activity wherein all 14 of the students separate into groups. During “centers”, Jason’s kindergarten teacher will be conducting observation to measure Jason’s on task behavior. She will need to conduct this measurement without any paraprofessional support as she is the only adult in the classroom at this time. In this scenario, which of the following measures would be most appropriate for Jason’s teacher to utilize?
a. partial interval recoding
b. PLACHECK
c. duration
d. momentary time sampling
11. Which of the following should a behavior analyst consider when selecting a method to calculate interobserver agreement? (select all that apply)
a. whether the behavior is a free or restricted operant
b. whether the definition is a topographical or a functional one
c. the level of stringency that is desired/feasible
d. the measurement utilized
12. Which of the following is accurate when referencing a quasi design?
a. this design is synonymous with a between group design
b. this design does not require inferences
c. this design allows one to determine a causal relation
d. this design approximates other experimental designs
