Questions and CORRECT Answers
4 common Single Case Designs - CORRECT ANSWER - ABAB, Multiple Baseline,
Changing Criterion, Alternating Treatment
ABAB Reversal Design - CORRECT ANSWER - type of experimental design in which an
intervention is introduced, withdrawn, and then reinstated, and the behavior of a participant is
examined on and off the treatment
Multiple Baseline Design - CORRECT ANSWER - Implemented across different skills,
participants, or settings.
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). After maximum
change has been noted in the first behavior, the treatment variable is applied in sequential fashion
to each of the other behaviors in the design.
The staggered implementation is important when demonstrating experimental control and a
functional relationship in multiple baseline designs.
Changing Criterion Design - CORRECT ANSWER - A type of single-subject design in
which the effect of the treatment is demonstrated by how closely the behavior matches a criterion
that is systematically altered.
Each phase is a change in criterion. Each change acts as baseline for the phase, demonstrating
replication
Alternating Treatments Design - CORRECT ANSWER - an experimental design in which
two or more conditions are presented in rapidly alternating succession independent of the level of
responding
, Baseline is not necessary in alternating treatment designs.
determines which intervention is most effective
Single Case Design Questions - CORRECT ANSWER - Demonstration - to what extent
will the intervention work?
Parametric - does more or less of the intervention work better?
Component - how effective is the intervention when various components are added or
subtracted?
Comparative - does one intervention work better than another?
Single Case vs. Group - CORRECT ANSWER - Single Case -
Experimental control
Participant serves as their own control
Variables are measured repeatedly and defined operationally
IV is manipulated actively
Group -
typically produces correlational results
experimental and control groups
treatment results are generalized
fidelity data is typically not collected
Advantages of SCD - CORRECT ANSWER - tests conceptual theories
validates intervention effectiveness
focuses on the individual
demonstrates generalization
cost-effective and reliable
