ABA 515 Cumulative Exam Flashcards
(195 cards)
What are probes in ABA research?
Intermittent assessments used to determine if behavior change has generalized or maintained.
What are two meanings of the term ‘probe’?
- A method to assess performance
- A design feature in a multiple-probe design
Give three reasons to use a multiple-probe design.
- Behavior needs structured trials
- Repeated measures could harm learning
- Still meets design criteria when embedded in a multiple baseline
How is randomization used in alternating treatment designs?
Conditions are presented in a random order to reduce bias.
How is randomization used in multiple baseline designs?
Start times or treatment orders are randomized.
What is a combined design?
A research design that blends features of two or more single-case designs to strengthen conclusions.
What is a mini-reversal?
A brief return to baseline or altered condition to verify intervention effects without ending the whole treatment.
What are transfer of training and response maintenance?
Transfer: Behavior generalizes to new settings
Maintenance: Behavior continues after intervention ends
What is statistical regression and why is it a problem in single-case design?
It’s when extreme scores naturally move toward the average, which can be mistaken for treatment effects.
What is the guideline for phase duration in single-case research?
Phases should continue until clear, stable patterns are observed — not based on arbitrary durations.
What are two risks of shifting phases too early?
It can confound results and reduce internal validity.
What are two criteria for deciding when to shift phases?
- Use explicit decision rules
- Base decisions on stability and trend, not just time
What are practice effects?
Improvements due to repeated exposure to a task, not because of the intervention.
What is variability and why is it important?
Fluctuations in data — large variability makes it harder to detect treatment effects.
List four causes of variability in single-case designs.
Observer drift, environmental changes, inconsistent procedures, inherent behavior variability
What is the purpose of outcome research in ABA?
To determine whether interventions work under real-world conditions.
What is a constructive strategy?
Adding a new component to an effective intervention to enhance outcomes.
What is a parametric strategy?
Testing different levels (e.g., more or less) of an independent variable.
What is a comparative strategy?
Comparing two different interventions to see which is more effective.
What are two defining features of single-case designs?
Repeated measurement and replication within the same participant.
What is the difference between single-case and group design?
Single-case: Few participants, many observations
Group design: Many participants, few observations each
List the four strengths of single-case designs.
Ongoing feedback, individual focus, generality, evaluation of effectiveness
Why does Kazdin promote single-case research?
It allows flexibility, feedback, and evaluation of individual responses, especially in applied settings.
What are multiple-probe designs used for?
To evaluate behavior change without continuous baseline data, often used when frequent testing could affect behavior.
