Psychology Chapter 9: Alternating Treatments Design

Questions and Answers

What is the basic goal of an Alternating Treatments Design?

Using a single treatment for all subjects

Collection of baseline data before treatment

Presentation of treatments simultaneously

Comparison of the effects of two or more treatments on the same behavior (correct)

What is an Alternating Treatments Design With No Baseline?

Treatments are presented randomly to the subjects across different days or times without pre-intervention baseline data.

What does it mean when an Alternating Treatments Design has a baseline?

Baseline data are collected before the presentation of the treatments to provide information about changes.

Study Notes

Alternating Treatments Design Overview

Aims to compare effects of multiple treatments on the same behavior.
Can be executed with or without baseline data.

Alternating Treatments Design Types

Without Baseline: Treatments are presented randomly on different days or sessions; no initial data collected but may include alternating no-treatment phases.
With Baseline: Collects baseline data prior to treatment, allowing for bigger insights when evaluating treatment effectiveness.
With Final Treatment Phase: Concludes with the treatment determined to be most effective based on the preceding analysis.

Key Concepts

Multiple Treatment Interference: Occurs when the effect of one treatment influences other treatments, potentially skewing results.
Prediction: Each data point must verify previous predictions to confirm effectiveness of treatments.
Verification: Successive data points should support the predictions made from earlier data, demonstrating consistency.
Replication: Treatment effects are valid if observed trends continue across sessions.

Practical Considerations

Intercomponent Interval Length: Duration a treatment is applied; longer intervals facilitate better discrimination between treatments by subjects.

Methodologies in Treatment Design

Multielement Design: Identifies factors in functional behavior analysis that affect behavior, aiding in intervention selection.
Simultaneous Treatments Design: Also known as concurrent schedules design; sustains all treatments at the same time, posing planning challenges.
Adapted Alternating Treatments Design: Applies the intervention to multiple, similar yet functionally independent behaviors, expanding the scope of treatment evaluation.
