Threats to internal validity include:
Testing, maturation, procedural infidelity
Match the definition. 2A. Events that occur during the experiment but that are not related to planned
procedural changes that may influence the outcome
History
2B. Changes in behavior due to the passage of time
Maturation
2C. Occurs when participants need to respond to the same test repeatedly during a baseline or probe
condition, which influences responding
Testing
Threats related to the measurement system, and are of concern because of repeated measurement
by human observers who may make errors
Data instability
Inconsistent implementation of the experimental condition
Procedural infidelity
The loss of participants during a study, which limits the generality of findings
Attrition
Occurs when a participant's behavior is influenced by more than one planned intervention during the
course of a study
Multiple treatment interference
A type of data instability that refers to a repeated and predictable pattern in the data series over time
Cyclical variability
Carryover Effects
-Refers for an effect of being tested in one state on participants' behavior in later situations
- May occur in a within-subject trial when the effect of a particular level of the self-independent
variable persists even after the treatment finishes
The hypothesis that states that there is no significant difference between samples is:
The Null Hypothesis
Amanda is an RBT at an ABA clinic. She is working with her client, Jerrell, to decrease aggressive

number):
Dr. Jones wanted to know if the use of the Good Behavior Game decreased rates of disruptive
behaviors in an elementary school. Dr. Jones collected data throughout the duration of the school
year across two elementary schools. In school A, all k-6 classrooms used the Good Behavior Game. In
School B, no classrooms used the Good Behavior Game. At the end of the school year, Dr. Jones
concluded that the Good Behavior Game had no impact on student disruptive behavior, when in fact
it had. This is an example of:
A Type 2 Error
The primary purpose of the method section is to:
Detail the plan of study being proposed.
allows the readers to evaluate and judge the study's validity and reliability

A change in variability
Which of the following is a limitation of using statistical significance to differentiate between

All of the above
Dr. Lestremau is employed in a large urban school district with 10 elementary schools. She wants to
evaluate the effects and feasibility of peer-mediated, school-based, discrete trial training for teaching
multiplication skills to six students with autism spectrum disorder. She will collect on-going and
frequent measurement of students' fluency with multiplication facts. Dr. Lestremau is using:
Single case research design methodology
Kacyn is a BCBA at an ABA Center. She is running a small social skills group with 6 children who have
autism spectrum disorder. Kacyn is using the "Tough Kids Social Skills Curriculum." The goal of the
social skills sessions is to build basic social entry skills (e.g., making eye contact, greetings, responding
to name). Prior to the start of the group, Kacyn collected data for each of the participants. Specifically,
she asked the therapists to complete the BASC-2 (a rating scale that measures changes in behavior
and emotional status) and also collected the frequency of spontaneous greetings during a 30-minute
observation period. She continued to collect data for spontaneous greetings during and after
implementation of the social skills group. What is the dependent variable?
The frequency of spontaneous greetings
