SSRD is commonly used to examine the changes in the behavior of an individual as a result of treatment.

Problem Observation
The subject of the experiment is a 21-year-old African female named Maggie. She came to the United States two years ago to attend medical school at the Texas College of Osteopathic Medicine at the University of North Texas Health Science Center (UNTHSC). The other members of her family still reside in Nigeria and her ability to communicate or visit is limited due to a lack of time and finances. At the tender age of 3 months, Maggie’s parents enrolled her into daycare. Her mother was a bank manager and her father was a corporate lawyer; both parents had busy schedules and could not take care of Maggie on their own. Upon completing elementary school Maggie was immediately enrolled into a boarding school in Ghana. Once again her parents failed to give her social support causing Maggi to feel unloved by her family.

It is possible that changes in Maggie’s mood and behavior during the treatment phase were a result of unknown environmental events not related to the treatment. For example, Maggie while enabling Maggie to interact and join social groups she could have met a significant other that affected her treatment; even if her significant other aided in reducing her depression he would still be a variable that was not controlled for in the experiment. Due to the successful outcome, it is tempting to accept the results of the AB design and conclude that the treatment had an effect when decrease levels of baseline behavior (A) are followed by gradual or dramatic increases due to the introduction of the treatment (B). But the truth of the matter is that proper control procedures were not present.

They believe the theory of evolution cannot be true because it does not bring in to play the intelligent designer himself. In other words, intelligent design is a theory centered on religion. And if intelligent design is unscientific and religiously in nature, why should this one theological idea be given time over all the others if it were to be taught in a science course. Most intelligent design supporters imply there is only one creator or intelligent designer: in other words a monotheistic creator....   [tags: personal beliefs on academics]
