Unit 9 Flashcards
A research design consisting of a baseline and a treatment phase.
AB design
A three-phase experimental design consisting of an initial baseline phase (A) until steady state responding (or counter therapeutic trend) is obtained, an intervention phase in which the treatment condition (B) is implemented until the behavior has changed and steady state responding is obtained, and a return to baseline conditions (A) by withdrawing the independent variable to see whether responding “reverses” to levels observed in the initial baseline phase.
ABA design
An experimental design consisting of (1) an initial baseline phase (A) until steady state responding (or countertherapeutic trend) is obtained, (2) an initial intervention phase in which the treatment variable (B) is implemented until the behavior has changed and steady state responding is obtained, (3) a return to baseline conditions (A) by withdrawing the independent variable to see whether responding “reverses” to levels observed in the initial baseline phase, and (4) a second intervention phase (B) to see whether initial treatment effects are replicated.
ABAB design
An experimental design that corresponds to an A-B-A-B design, where the second baseline is replaced with a placebo phase (B).
ABCB design
An experimental design in which two or more conditions are presented in rapidly alternating succession independent of the level of responding; differences in responding between or among conditions are attributed to the effects of the conditions.
Alternating treatment design
A three-phase experimental design that begins with the treatment condition. After steady state responding has been obtained during the initial treatment phase (B), the treatment variable is withdrawn (A) to see whether responding changes in the absence of the independent variable. The treatment variable is then reintroduced (B) in an attempt to recapture the level of responding obtained during the first treatment phase.
BAB design
A research design in which a number of different goal levels are set for the behavior during the treatment phase.
Changing criterion design
A variation of the multiple baseline design in which an initial baseline, and perhaps intervention, are begun for one behavior (or setting, or subject), and subsequent baselines for additional behaviors are begun in a staggered or delayed fashion.
Delayed multiple baseline design
An experimental technique that demonstrates the effects of reinforcement. Differential reinforcement of an incompatible or alternative behavior are used as a control condition, instead of a no-reinforcement condition.
DRI or DRA reversal technique
An experimental technique for demonstrating the effects of reinforcement by using differential reinforcement of other behavior as a control condition instead of a no-reinforcement (baseline) condition.
DRO reversal technique
Occurs when two observers independently observe and record a person’s behavior at the same time and agree on the occurrence of the behavior.
Interobserver agreement
A research design in which there is a baseline and a treatment phase for two or more behaviors of the same person.
Multiple baseline across behaviors design
A research design in which there is a baseline and treatment phase for the same behavior of the same subject in two or more different settings.
Multiple baseline across settings design
A research design in which there is a baseline and treatment phase for two or more people exhibiting the same target behavior. The implementation of treatment is staggered across time for each subject.
Multiple baseline across subjects design
An experimental design that begins with the concurrent measurement of two or more behaviors in a baseline condition, followed by the application of the treatment variable to one of the behaviors while baseline conditions remain in effect for the other behavior(s).
