SPCE 630 FINAL EXAM

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 behaviors (i.e., biting others). She has collected data for the frequency of Jerrell's bites for three weeks. Calculate the mean, median, and mode of the following data set (round to the nearest whole number): Week 1: 12, 11, 10, 22, 22 Week 2: 7, 8, 13, 21, 17 Week 3: 16, 7, 9, 3, 0 Mean= 12, Median=11, Mode=7,22 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 Which fo the following is true about single case research design? Most studies include one participant These data show which of the following: A change in variability Which of the following is a limitation of using statistical significance to differentiate between meaningful and trivial change? All of the above Which of the following is a limitation of group design? 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 greetin
