PTSD and the scientific method

In this module's SLP assignment, you will take a break from the anatomy and physiology of stress to analyze the work you have done so far, specifically in your Module 3 Case Assignment.

The readings you accomplished for Module 3's Case Assignment are quite new scientific theories that are currently being tested by scientists who are trying to figure out why individuals suffer from behavioral issues such as depression and PTSD. The scientific and medical communities have collected a lot of evidence that stress plays a very big role in not only creating these behaviors, but also perpetuating them. We still have a long way to go and many unanswered questions!

By completing *Case 3, you have participated in the **scientific method. After you view this linked animation, use this ***diagram as your reference point to complete the following components of this assignment:
- In which part of the Case Assignment did you address Step 1, "observe and generalize"?
- Which part of the Case Assignment required you to accomplish Step 2, "formulate a hypothesis"?
- Did your hypothesis contain information that can be accepted as the absolute truth? If not, what information was missing? (HINT: Think back to the studies about cortisol and PTSD.) Based on the information that was missing from your hypothesis, what could you test in order to obtain more information on the unknown piece?
- Do a bit of research on the technology available today that could facilitate this test. Examples of new technology include brain imaging, blood chemistry and hormone level tests, CAT scans, MRIs, and DNA mapping. What step of the scientific method does this require?
- Now that you have some additional information, briefly and in simple terms, describe how you would test the missing information and which step of the scientific method this accomplishes.

During the observation phase, subjects are gathered for observational study or experimentation, depending on the design process used. The PTSD and Complement System part of Case 3 addresses Step 1, "observe and generalize", because in this part of Case 3, the brain activity levels of PTSD patients were observed, and generalizations regarding the complement pathway was made.

The hypothesis is a claim or statement that is testable. The Conclusion of Case 3 required me to accomplish Step 2, "formulate a hypothesis". In the Conclusion of Case 3, the presumed connections between the influence of stress on the immune system were explained. The hypothesis was the statement made that provided a picture of what happens to the immune system as stress occurs. The hypothesis can be tested using the scientific method. Research can be conducted, and data gathered to determine if the hypothesis will be rejected or not rejected.

My hypothesis contained some information that cannot be automatically accepted as the absolute truth. It is unclear how the regulatory mechanism of cortisol impairs a person's physiological and ...
