One risk to the demonstration of experimental control when using a B-A-B design is that the behavior improves during the B condition and deteriorates during the A condition. improves during the B condition. doesn't deteriorate during the B condition. doesn't deteriorate during the A condition.

doesn't deteriorate during the A condition. In a reversal design, to demonstrate experimental control, there has to be at least two changes in level or trend-one corresponding to the onset of baseline condition and one corresponding to the offset of the baseline condition. If the behavior doesn't deteriorate during the A condition, there is no difference between the initial B condition and the A condition; therefore, no opportunity for a reversal. (Cooper, Heron, & Heward., 1987, pp. 174-175 Cooper, Heron, & Heward, 2007, p. 180)

In an A-B-A design, a reversal occurs when
baseline is re-introduced and the behavior approximates the level during the original baseline.
baseline is re-introduced and the behavior is maintained.
the intervention is introduced and the behavior remains at the level during the original baseline.
baseline is re-introduced and the behavior returns to the level during the original intervention.

baseline is re-introduced and the behavior approximates the level during the original baseline.

6

A reversal design can be designated as
A-B-A, where A=baseline, B=intervention.
A-B, where A=baseline, B=intervention.
A-B-C-A, where A=baseline, B=intervention 1, C=intervention 2.
A-B-C, where A=baseline, B=intervention 1, C=intervention 2.

 A-B-A, where A=baseline, B=intervention.

an alternating treatments design.
a reversal design.

Which design could provide the most valid non-intervention measure with a demonstration of experimental control?
B-A-B-A-B
A-B
A-B-A-B
B-A-B-A

 A-B-A-B

With any design that begins with an intervention, you will never know for sure what the "natural" non-intervention (true baseline) rate would be. That is, the intervention may permanently change the behavior. Also, each reversal adds to the demonstration of experimental control. (Cooper, Heron, & Heward., 1987, pp. 163-167, 174-175; Cooper, Heron, & Heward, 2007, p. 196)

With a reversal design, each reversal
strengthens the demonstration of experimental control.
strengthens the demonstration of generalization.
weakens the demonstration of experimental control.
weakens the demonstration of generalization.

 strengthens the demonstration of experimental control.

A functional relation using a reversal design calls for (minimally)
baseline followed by implementation in a step-wise fashion across subjects.
baseline and two interventions.
two alternations between the baseline and a particular intervention.
two or more subjects.

two alternations between the baseline and a particular intervention.

"A" represents the baseline condition, "B" represents one intervention condition, and "C" represents a second intervention condition. (Cooper, Heron, & Heward., 1987, pp. 163-167; Cooper, Heron, & Heward, 2007, pp. 176-199)

ALTERNATING TREATMENTS (simultaneous treatments, multielement multiple schedule)--rapid alternation between two or more treatments
MULTIPLE BASELINE--staggered implementation of the intervention in a step-wise fashion across subjects, settings, or behaviors
REVERSAL (withdrawal)--alternation between baseline and a particular intervention
(Bailey & Burch, 2002; Cooper, Heron, & Heward., 1987, pp. 162-218; Cooper, Heron, & Heward, 2007, pp. 176-219; Poling et al., 1995; Tawney & Gast, 1984)

Which could provide the strongest demonstration of experimental control?
A-B-A
multiple baseline design across two subjects
A-B-A-B-A
B-A-B

Due to the risk of serious injury, you need to intervene on a behavior immediately. What experimental design should you use?
B-A-B
