BACB Task List 5
A-B Design - correct answer A two phase experimental design consisting of a pre-
treatment baseline condition (a) followed by treatment condition (b)
A-B-A Design - correct answer a three phase experimental design
(a) inital baseline [until steady state of responding]
(b) implementation of until bx has changed and steady state of responding
(a) return to baseline conditions by withdrawing the independent variable
A-B-A-B - correct answer inital baseline phase (a)
until steady state of responding
initial intervention phase in which the treatment variable (b) is implemented until bx
changed and steady state of responding occurred
return to baseline conditions (a)
by withdrawing the independent variable to see if responding "reverses" to level in
initial baseline
second intervention phase (b)
to see if treatment effects can be replicated
Verification - correct answer accomplished by demonstrating prior level of baseline
responding would have remained unchanged had the independent variable not been
introduced.
Replication - correct answer repeating independent variable manipulations
conducted previously in the study and obtaining similar outcomes
The most straightforward and most powerful within subject design to show
functional relations - correct answer A-B-A-B reversal
