Study Notes
Alternating Treatment Design
- Rapid alteration of two or more treatments to measure effects on target behavior.
- Experimental conditions can change daily, per session, or within a session.
- Effective in demonstrating experimental control when data paths show little overlap, with one consistently higher.
- Helps protect against threats to internal validity like participant attrition and lack of baseline data.
- Requires semi-random exposure to each intervention.
Control of Influences in Alternating Treatments
- Addresses maturation effects (subject changes during the experiment).
- Mitigates data instability and sequence effects (previous treatment influences current treatment).
- Reduces issues related to participant attrition.
Advantages of Alternating Treatments
- No need for treatment withdrawal.
- Allows for quick comparisons between different treatments.
- Minimizes irreversibility and sequence effects.
- Suitable for unstable data patterns and can assess generalization.
- Allows for immediate intervention initiation.
Multiple Treatment Interference
- Previous treatment effects can impact current treatment outcomes.
- Follow-up with a single treatment phase to evaluate behavior effectively.
Multiple Treatments Design
- A reversal design assessing effects of multiple independent variables relative to one another.
- Examines differences by comparing conditions through an A-B-A structure.
Simultaneous Treatments (Concurrent Schedules)
- Involves two or more concurrently operating contingencies where the subject "chooses" the intervention.
- Requires data paths to align on graphs for accurate analysis.
Reversal Design
- Involves implementing and withdrawing an intervention (ABA design).
- Highly susceptible to sequence effects and may face ethical concerns in effective treatment withdrawal.
- Requires at least two reversals to substantiate a functional relationship.
Changing Criterion Design
- Evaluates treatment effects applied in a step-wise or graduated manner to a single behavior.
- Applicable only to behaviors already within the individual’s repertoire.
Guidelines for Changing Criterion
- Each new phase should serve as a baseline for the next, requiring stability in responses.
- Phase lengths should vary significantly to enhance validity.
- Changes in the size of criteria help demonstrate experimental control.
Multiple Probe Design
- Utilizes a multiple baseline approach with discontinuous measurement for teaching behaviors.
- Ideal for behaviors that require sequential teaching steps.
Multiple Probe Procedure Steps
- Collect 1-3 probes for each step.
- If stable low data is observed, implement intervention for the first step until mastery.
- Conduct new probes for all steps and repeat until all criteria are met.
Multiple Probe and Experimental Control
- Demonstrates control by measuring learner performance before training, during, and after mastering skills.
Multiple Baseline Design
- Conducts simultaneous baseline measurements on multiple behaviors.
- Interventions are staggered after achieving stable baselines, applied to one behavior at a time.
Experimental Control in Multiple Baseline
- Experimental control is shown when behaviors change only upon implementation of the independent variable.
Forms of Multiple Baseline
- Across settings: same behavior in different environments.
- Across behaviors: same subject exhibiting different behaviors.
- Across subjects: same behavior across different individuals.
Utility of Multiple Baseline
- Effective for interventions targeting dangerous behaviors or those with irreversible impacts.
Ensuring Experimental Control in Multiple Baseline
- Select independent baselines that do not influence each other, yet are similar enough for expected intervention effects.
- Vary the lengths of baselines and delay intervention until stability is ensured for increased control strength.
Predictions in Multiple Baseline Designs
- Predict behavior occurrences without intervention by analyzing baseline data.
- Verify by comparing target behavior rates under intervention with those remaining in baseline, confirming effects replication with each application of the intervention.
