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 the 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 Designs

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

Withdrawal 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
