Part 1
Jane, a military psychologist, wants to examine two types of treatments for depression in a group of military personnel who have suffered the loss of their legs. She has only 20 men to work with.

  • What would be the best research design for the study and why?
  • What are some issues that Jane needs to consider before starting the study?
  • What is a longitudinal study? What are the benefits and challenges associated with a longitudinal study?
  • Using the South University Online Library find two peer-reviewed articles (one that has used a between study design and one that has used a within study design) Summarize both of these articles. Make sure you discuss the research design specifically.
  • Explain what practice and carryover effects are in the context of the within subjects design study that you found. What steps did the researchers take to reduce these effects?

Part 2
Hector is a graduate student hoping to conduct research with statistically significant results. He is using a survey to investigate the ways in which medical students manage stress. He thinks they consume coffee, eat, and watch television. He wants to control for demand characteristics, and does not want his bias to influence his results. Answer the following questions regarding the approach he should take:

  • Is it ethical for Hector to use deceit in order to control for demand characteristics? Why or why not? Does it matter whether or not the documentation that his University’s Institutional Review Board (IRB) approved addressed the use of deceit? Why or why not?
  • What are three strategies Hector can use to identify and eliminate biases in his survey?
  • Do you think Hector’s body language or clothing can convey biases? Why or why not?
  • Hector is planning to recruit subjects and administer his survey in the Student Center (where students gather to converse, eat, and study) at his University. Is this a good way to control for demand characteristics? Why or why not?
  • The participants in Hector’s research are of different genders, ages, races, ethnicities, and religions. However all of them are current medical students. Is it appropriate for him to make a generalization based on the results of his research? Explain your reasoning.

Conducting an ethnographic study

Conducting an ethnographic study is a fun way of gathering research about your social environment. You may have done an ethnography before without really being aware of it. In a small way, this assignment recreates what ethnographers do when they visit a new community to conduct research.
Complete the following:Observation

  • Choose a restaurant, library, mall, dining hall, coffee shop, or similar public location. Plan to spend a minimum of two hours at the location. You will visit this location twice, for a minimum of four hours total. Keep in mind that if you should find one of your peers in the establishment at the same time when you are there, do not interrupt him/her and do not do the assignment at the same time.
  • Document what occurs at this chosen location:
    • Describe the establishment.
    • Analyze the interactions between people.

Next, write a paper documenting and analyzing your observations of the location.
Observation Notes
Your observation notes should specifically include the following:

  • Name and location of the establishment
  • Dates and times you were there
  • Place where you stood/sat and when you did your research
  • Description of the physical characteristics of the inside and outside of the establishment (e.g. brick or concrete structure, paint color, seating arrangements)
  • Number and types of people visiting the establishment while you were there (age, sex, type of clothing, probable occupations, ethnicity, etc.)
  • Document interactions such as:
    • specific nature of the interactions that take place in the establishment among customers, between customers and staff, and among staff
    • types of languages used in the establishment and by whom
    • any strange or unusual behavior

Analysis Summary
Include the following in your analysis:

  • Comparison of similarities and differences of this establishment and other similar establishments you know about
  • Nature of the treatment of customers in the establishment
  • Relationships between customers and workers
  • Any behavior that surprised you or was contrary to your expectations
  • How it felt to do the research
  • Most difficult aspects of the research
  • What you found most interesting about the research

In your analysis, be sure to draw upon your observations to support your conclusions.
Appendix
In the appendix of your paper, include the following:

  • A sketch of the layout of the establishment (You can draw in a computer program, like Paint that comes preloaded on most PCs and insert it into your Word file.)
  • Transcription of your notes

Write a 4–6-page paper in Word format. Apply APA standards to citation of sources

Briefly describe the need to validate the result of any research study

Think in relation to a college professor, John, who claims he is a superior teacher because his Introduction to Psychology class performed better than the class taught by another teacher Drew, did on their final exam.

  • Briefly describe the need to validate the result of any research study
  • Is it important for a study to have high internal validity? What if Drew’s students had to take the exam during a time when construction was going on outside the window? What if there is suspicion of cheating on the part of a number of John’s students? Use the concepts of internal validity and discuss the problems with John’s claim.
  • Consider the same concept for external validity. What conditions must be met inside the college to be able to have high external validity? What are the advantages of conducting experiments in a laboratory (box-like environment)?
  • If John were to use this information to support his teaching strategies in a publication, would this be an example of accurate reporting of information? Why or why not?

Justify your answers with appropriate reasoning and research and comment on the postings of at least two peers.
Part 2
In last week’s discussion, we mentioned Jane, a military psychologist, who was examining treatments for depression in a group of military personnel who have suffered the loss of their legs. She has only 20 men to work with.

  • What are some things that Jan should consider to ensure that there is high internal validity in her study design?
  • What are some things she should think about when it comes to ensuring high external validity? Is it necessary for Jane to conduct her study in the laboratory (or can it be done in the field)? How will this influence validity?

Research Methodologies
In this assignment, you will examine the importance of scientific methods and critical thinking in research.
Using the Internet, research the following:

  • Scientific methods in research
  • Critical thinking in research

Scenario
In 2007, a world famous violinist, Josh Bell, whose ticket prices averaged $100 each in a concert in Boston, played a $3.5 million handcrafted violin posing like a street musician in a Washington D.C. metro station. This experiment was done to note how many people would stop and listen to his beautiful performance. He made a mere $32 that day. The experiment concluded that very few people stop to appreciate the good things in their daily life.
Based on your research and the scenario, discuss the following about the methodology used:

  • Do you think the method used was scientific? Justify your answer.
  • Do you think any other method could be used to collect data to study such behavior? Why?
  • How does research shape the scientific field?
  • Have the steps of research been followed in the above experiment? Justify your answer.

Scientific thought involves critical thinking. Defining critical thinking is not as easy as it seems. Critical thinking is often referred to as thinking of unique ways of experimenting.

  • Do you think the above experiment involved critical thinking? Why or why not?
  • Define critical thinking in your own words and explain how it is used in research.

Media often takes advantage of such experiments. They could report experiments irresponsibly to make it saleable. How can the above experiment be presented irresponsibly?
