Deck 14: The Experimental Single-System Designs: A-B-A, A-B-A-B, B-A-B

Question 1

A design that turns out to be A-B-A-B-A-B also is an experimental removal design, and thereby offers the logical basis for inferring causality.

Answer 1

True

Question 2

A design that turns out to be B-A is not an experimental removal design, and it cannot claim any logical basis for inferring causality.

Answer 2

True

Question 3

Use of an A-B-A-B design can unequivocally prove that it was your specific technique that produced the changes.

Answer 3

False

Question 4

The experimental design that would probably be most suited for emergency situations would be:

A) A-B-A
B) A-B-A-B
C) B-A-B

Question 5

The major factor determining when to change phases is:

A) Length of phases
B) Stability in the data
C) Carryover effects
D) None of the above

Question 6

The main thing carryover effects do when they are present is:
a) Clarify causality exists
b) Decrease stability
c) Demonstrate reversibility
d) None of the above

Question 7

The A-B-A-B design tends to protect from the following threat or threats to internal validity:

A) History
B) Maturation
C) Testing
D) All of the above
E) None of the above

Question 8

In an experimental removal design, the practitioner has to have a B intervention that attains positive improvement (in comparison with the baseline data) before removing that B and returning to an A condition (baseline).

Question 9

A major reason for using the B-A-B design is that one can begin to work with the problem immediately and still have a logical basis for determining both change and possible causality.

Question 10

A practitioner removes a successful intervention because he/she wishes to test a research hypothesis about causality, which requires that an experimental removal take place.

Question 11

I applied my intervention in the third phase to Angelina's walking instead of her sitting still. This design is most precisely called:

A) Removal
B) Withdrawal
C) Reversal
D) Experimental

Question 12

Carryover effects are always the same as irreversibility.
