Chapter 2 - Research Methods Flashcards
Single-subject designs
studies requiring only one or a few participants to conduct an entire experiment
Case studies vs. SS designs
case studies describe, SS designs manipulate
Advantages of single-subject designs
we don’t lose information due to averaging, more efficient and specific to individuals
Disadvantages of single-subject designs
we lose external validity and generalizability
Baseline
the normal frequency of a behavior that occurs before intervention
A-phase
baseline period
B-phase
treatment or experimental period
True or False: no statistics are used in SS designs
True !
Simple comparison design (AB)
comparing behavior in a baseline condition to behavior in a treatment condition
What is the disadvantage to a simple comparison design?
poor internal validity
Reversal design (ABA/ABAB)
involves repeated alternations between a baseline period and a treatment period
Limitations of a reversal design
cannot be used when intervention causes permanent changes or when it would be unethical to remove an effective intervention
Multiple baseline design
a treatment / intervention is instituted at successive points in time for two or more persons, settings, or behaviors
Multiple baselines across persons
measuring behavior across 2 + people
Multiple baselines across settings
measuring behavior of one person in 3 different settings
Multiple baselines across behaviors
measure more than one target behavior
Benefits of multiple baseline design
appropriate where treatment may cause long-term change and where removal is unethical
Limits of multiple baseline design
more complex design, when used on same person effects may generalize across settings / behavior
