Phillip has received a referral to work with a student in a local school. He would
like to develop a plan that will reduce the problem behavior while increasing the
likelihood of a preferred behavior. In order to accomplish this, he conducts an FBA
and then confirms the results with an FA. He then ensures proper training of the
intervention to ensure that it will be implemented with fidelity. He develops an
extensive data collection system to review the effect of the intervention on the
behavior, and even asks the teacher to stop using the intervention for a period of
time to determine whether the behavior returns to pre-intervention levels
without the support. Ultimately, as a scientist-practitioner, he would like to have
what effect on the behavior?
Control
High levels of internal validity are achieved by:
Controlling confounds
Which of the following are potential sources for confounds?
All of the above
When developing a research design, the researcher should attempt to avoid
exposing the participant to the assessment too often, especially if there is a
chance that the participant will develop his/her skills with this particular
assessment through exposure. By doing so, the researcher is reducing the risk of
which threat to validity?
Testing
, 2
External validity refers to the extent to which:
Similar results would be obtained under different conditions
External validity is obtained in single subject research by:
Multiple replications across different subjects/conditions
The definition of a target behavior should always be described as:
All of the above
Explicit behavior definitions are important to the practitioner of applied behavior
analysis for all of the following reasons except:
Increased likelihood of behavior change
When the definition of the target behavior focuses on the form of the behavior, it
should be considered what kind of definition?
Topography-based definition
A(n) ____________ behavior is a behavior that produces indirect benefits to
clients by potentially increasing opportunities for participation in other
environments.

Melanie would like to investigate the effect of "Spinning Therapy" on the verbal
behavior, specifically the use of intraverbals, of adults on the Autism Spectrum.
She worries that the more time they spend listening to music, the more she will
be unable to determine the effect of her intervention. Based on this plan, what
would be the independent variable?

Steve is a researcher who has primarily investigated the effectiveness of various
interventions with young children identified on the Autism Spectrum enrolled in
early intervention programs. However, Steve believes that many of the
interventions studied may also be effective with older children in a school setting.
In order to ensure that the interventions he develops are implemented in the
settings and with the population that he did not initially test, Steve needs to make
sure that he designs a study with a high degree of what?
external validity
Emma goes to great lengths during her research to graph her data with a high
level of precision. She reviews her graph often to ensure that she has adequate
information to evaluate the level, trend, and variability of the data collected.
Which kind of validity is Emma focused on through her efforts?
Data-evaluation validity
The researcher notices that Arianna's performance during the study is highly
variable. After further investigation, he discovers that her performance seems to
be better when data are collected in the morning. Which type of confound may
be to blame?
Measurement
Dan is investigating the effectiveness of a token economy system on social skill
development of one of his clients. He begins to notice that after a sharp increase
in social skill behaviors at the start of the intervention, his client suddenly
decreases his frequency of the preferred behavior. Dan decides to investigate the
implementation fidelity of the intervention and learns that the token economy is
now being used in the setting not only with the social skill behaviors, but also with
cleaning behaviors, which happen to be a preferred task for the client. With this
information, Dan should be concerned with which threat to validity?
Diffusion of treatment
