To examine how a reward influences a desired behavior, a mother first counts the number of times her son makes his bed over a two-week period. for the next two weeks, she gives him a reward every time he makes his bed. following this period, she stops rewarding him and again counts the number of times he makes his bed. this procedure would be an example of a(n) design. a. pretest-posttestb. baseline treatmentc. control seriesd. aba

D - ABA design.

Explanation:

ABA isn't an acronym but it does represent the stages of the model called Single Subject Experimental Design. "A" represents the initial behavior which is the base of the study. "B" represents the intervention to that behavior. Then, after the intervention the initial behavior is analyzed and so on until the desired effect or goal is achieved. In the exercise this design is described: "A" represents a boy making his bed. "B" is the mother rewarding that behavior. Like in the ABA model, the initial behavior is altered by the intervention and then the intervention is withdrawn to see if the behavior returns to the baseline level.
