CHILD PROBLEMS IN BEHAVIOR ANALYSIS
CHAPTER 3 NOTES
PART ONE
1.Descriptive: characterizes the level of behavior existing before intervention.
2.Predictive: predicts the future level of the target behavior in the absence of the IV or if the IV
has no effect; serves as a criterion to evaluate whether the intervention produces change.
3.A-B design: basement followed by a treatment phase; effect demonstrated when behavior
changes from one phase to the next.
4.AB Design Limitations: - recommended only when there is no other way to get data
- sometimes appropriate in clinical settings
- however, supports only weak conclusions
- changes may be the result of extraneous variables
5.ABAB design: • likelihood is small that some extraneous variable produced behavior change
• limitations:
• may be unethical to reverse treatment
• some changes are not reversible
• behavior, after initial change, makes contact with other variables that make reversal unlikely
even if intervention is withdrawn
6.Multiple Baseline Design: - two or more independent baselines are established
- IV is separately introduced in a staggered fashion to each baseline
- when behavior is stable, the iv is introduced on the second baseline
7.Alternative Treatment Design: - multielement design
- rapid alternation of two or more IVs or levels of the IV
- each session has a different condition
8.Multi-element Design (Alternating Treatments): rapid alternation of two or more IV's
repeated measurement of behavior while the conditions alternate rapidly
IVs continue alternating independently of the level of responding
