Unit 5

Question 1

Repeated, systematic presentation and
removal of an independent variable (or IV)
While measuring changes in the dependent
variable (or DV) and holding other factors
constant

Answer 1

Experimental Design

Question 2

To demonstrate a functional relation

between the IV and DV and To evaluate the interventions once they are decided upon

Answer 2

The Primary goals of systematic experimental manipulation

Question 3

Changes in an antecedent or consequent
stimulus class consistently alter a dimension 
of a response class

Answer 3

Functional Relation

Question 4

The extent to which an analysis assures that
measured changes in behavior are due to
the manipulation and not due to uncontrolled
extraneous variables.

Answer 4

Internal Validity

Question 5

The extent to which a study’s results are
generalizable to other subjects, settings, or
behaviors.

Answer 5

External Validity

Question 6

History
Maturation
Testing
Instrumentation
Diffusion of treatment
Regression towards the mean
Selection bias
Attrition

Answer 6

Threats to Internal Validity

Question 7

Measurement
Stability
Immediacy
Replication

Answer 7

Minimizing Validity Threats

Question 8

The repeated and systematic presentation
and removal of a treatment and
measurement of behavior while holding other
factors constant

Answer 8

Single-Case Design (SCD)

Question 9

Assessment of the dependent variable prior
to the introduction or change of the
independent variable

Answer 9

Baseline

Question 10

Movement in the analysis from one level or
kind of independent variable to the next level
or kind of independent variable

Answer 10

Phase Change

Question 11

Baseline phase followed by a treatment phase
Effect is demonstrated when behavior
changes from one phase to the next

Answer 11

A-B Design

Question 12

Baseline is followed by a treatment

condition.

Answer 12

Withdrawl Design

Question 13

An intervention is applied to the target

behavior after a baseline phase

Answer 13

Reversal Design

Question 14

Two or more independent baselines are
established.
The independent variable is then separately
introduced in a staggered fashion to each
baseline.

When behavior is stable for the first baseline,
the independent variable is introduced on the
second baseline, and so on.

Answer 14

Multiple Baseline Design

Question 15

First baseline is continuous, but subsequent
baseline data collection is conducted on an
intermittent basis relative to the first baseline

Answer 15

Multiple Probe Technique
