SNA, Experimental Designs, Validity Flashcards
List the 4 main types of experimental designs
reversal/withdrawal,
multiple baseline,
alternating treatment,
changing criterion
List the 3 variations of Multiple Baseline Design
Multiple probe,
delayed multiple baseline,
non-concurrent multiple baseline
List the 4 variations of the Reversal Design
Repeated reversal,
BAB,
multiple treatment reversal,
DRI/DRA/DRO Reversal
List 3 of the advantages of a Multiple Baseline Design
Successful intervention not removed,
promotes generalization,
easy to implement
List 2 disadvantages of a Multiple Baseline Design
Only one intervention can be used,
some individuals may be delayed in
getting treatment
List the 3 types differential reinforcement reversal designs
DRA/DRI/DRO
List the 2 types of validity
Internal, external
T/F: The multiple baseline design is the
most widely used experimental design
in ABA.
True
T/F: Experimental control is
demonstrated when the independent
variable reliably produces the change
in the dependent variable.
True
T/F: Multiple probe Design uses
intermittent probes to provide the
basis to determine if behavior change
has occurred prior to the intervention
instead of simultaneous baselines.
True
T/F: Delayed multiple baseline design is
effective when limited resources
prevent a full-scale design to be
conducted.
True
T/F: An advantage of using a multiple
baseline design is that a functional
relationship is directly shown.
False, not directly shown
T/F: Reversal/withdrawal designs require
a baseline.
True
T/F: With repeated reversals, the more
reversals, the weaker the experimental
control.
False, stronger
T/F: . In a non-parametric analysis the
independent variable is either present
or absent.
True
T/F: Single-subject designs mean that
the experiment can only be used with
one subject.
False, subject serves as their own control
T/F: The A in an A-B-A design stands for
the intervention.
False, baseline
T/F: The most common type of multiple
baseline design is Multiple Baseline
Across Settings.
False, multiple baseline across subject
. #dosage
Parametric Analysis
A type of analysis where the
independent variable is either
on or off
Non-Parametric Analysis
. #MostWidelyUsed
Multiple Baseline Design
Each individual serves as their
own control
Single subject design
Uses NCR as a control instead
of going back to baseline to
show the effect of
reinforcement.
NCR Reversal
The most straightforward and
powerful within subject design
for demonstrating a functional
relation between an
environmental manipulation
and a behavior
ABAB
Any uncontrolled factor that is
suspected to exert influence on
the dependent variable
Confounding Variable
An aspect of the environment
that must be held constant
Extraneous Variable
Reversal, A-B-A-B, A-B-A are all
other names for this design
Withdrawal Design

Component Analysis
When looking at a single data point on a graph, it tells you:
When the behavior was recorded and the level of the behavior
An A-B design does not demonstrate a functional relationship between
variables because there isn’t any:
Replication
A researcher wants to see if a new drug enhances feelings during sex. The
researcher measures sensation for 5 participants for 7 days. Then, he
gives the drug to one participant for a week, prior to giving it to the next
participant. After the third week, the third participant also receives the
drug, and this pattern continues until all 5 participants receive the drug.
What type of experimental design does this demonstrate?
Multiple baseline across participants
The most unique thing about a single-subject experimental design is
that…
The subject serves as both the experimental and Control group
A problematic thing about averaging data is that….
-It eliminates variations in data
-you lose outliers
-Cannot examine individual differences
Dr. Now is conducting a series of experiments. He believes that he found a
way to have his patients rapidly lose weight. He wants to use a within
subject design that is considered to be the most powerful and
straightforward to demonstrate a functional relation between his patient’s
weight and his new treatment. What type of experimental design should Dr.
Now use?
ABAB
You are shopping for different types of make-up foundation. You by 3 and
then compare which brand matches best with your skin. What type of
analysis are you conducting?
Comparative analysis
Clint has a client who engages in SIB, aggression toward others and
thumbsucking. He has a treatment that he wants to use across all 3
behaviors. What type of experimental design would be best for this
scenario
Multiple baseline across behaviors
Dr. Oz is deciding what dosage of medication will work best for his patient.
What type of analysis should the doctor use?
Parametric analysis
A BCBA at a school system wants to study the effects of her new
intervention on 3 children at the school. However, there are limited
resources that prevent her from conducting a full-scale design. She also
wants to be able to have the flexibility to introduce the intervention if a
new subject becomes available. What type of design would best suit her
needs?
Delayed multiple baseline
SNABA wants to determine the effectiveness of pay bonuses on employees.
They decide to evaluate different levels of pay on employee’s performance
(DV) by offering $50, $100, and $500 bonuses. What type of analysis are they
using?
Parametric analysis
