Question 8

T/F: The multiple baseline design is the
most widely used experimental design
in ABA.

Answer 8

True

Question 9

T/F: Experimental control is
demonstrated when the independent
variable reliably produces the change
in the dependent variable.

Answer 9

True

Question 10

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.

Answer 10

True

Question 11

T/F: Delayed multiple baseline design is
effective when limited resources
prevent a full-scale design to be
conducted.

Answer 11

True

Question 12

T/F: An advantage of using a multiple
baseline design is that a functional
relationship is directly shown.

Answer 12

False, not directly shown

Question 13

T/F: Reversal/withdrawal designs require
a baseline.

Answer 13

True

Question 14

T/F: With repeated reversals, the more
reversals, the weaker the experimental
control.

Answer 14

False, stronger

Question 15

T/F: . In a non-parametric analysis the
independent variable is either present
or absent.

Answer 15

True

Question 16

T/F: Single-subject designs mean that
the experiment can only be used with
one subject.

Answer 16

False, subject serves as their own control

Question 17

T/F: The A in an A-B-A design stands for
the intervention.

Answer 17

False, baseline

Question 18

T/F: The most common type of multiple
baseline design is Multiple Baseline
Across Settings.

Answer 18

False, multiple baseline across subject

Question 19

. #dosage

Answer 19

Parametric Analysis

Question 20

A type of analysis where the
independent variable is either
on or off

Answer 20

Non-Parametric Analysis

Question 21

. #MostWidelyUsed

Answer 21

Multiple Baseline Design

Question 22

Each individual serves as their
own control

Answer 22

Single subject design

Question 23

Uses NCR as a control instead
of going back to baseline to
show the effect of
reinforcement.

Answer 23

NCR Reversal

Question 24

The most straightforward and
powerful within subject design
for demonstrating a functional
relation between an
environmental manipulation
and a behavior

Answer 24

ABAB

Question 25

Any uncontrolled factor that is suspected to exert influence on the dependent variable

Answer 25

Confounding Variable

Question 26

An aspect of the environment that must be held constant

Answer 26

Extraneous Variable

Question 27

Reversal, A-B-A-B, A-B-A are all other names for this design

Answer 27

Withdrawal Design

Question 28

. #Compare

Answer 28

Component Analysis

Question 29

When looking at a single data point on a graph, it tells you:

Answer 29

When the behavior was recorded and the level of the behavior

Question 30

An A-B design does not demonstrate a functional relationship between variables because there isn’t any:

Answer 30

Replication

Question 31

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?

Answer 31

Multiple baseline across participants

Question 32

The most unique thing about a single-subject experimental design is that…

Answer 32

The subject serves as both the experimental and Control group

Question 33

A problematic thing about averaging data is that….

Answer 33

-It eliminates variations in data -you lose outliers -Cannot examine individual differences

Question 34

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?

Answer 34

ABAB

Question 35

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?

Answer 35

Comparative analysis

Question 36

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

Answer 36

Multiple baseline across behaviors

Question 37

Dr. Oz is deciding what dosage of medication will work best for his patient. What type of analysis should the doctor use?

Answer 37

Parametric analysis

Question 38

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.

Delayed multiple baseline
