Before completing this discussion, be sure to review Chapter 4 of your text, and the REM Sleep video.  You may also find it helpful to explore the Eunice Kennedy Shriver National Institutes of Child Health and Human Development website from the recommended resources.

After examining the research in human development presented in your required resources, please choose and complete one of the following discussion options:

Option A: The brain goes through many changes as we age. Select and examine a developmental phase (infancy, childhood, adolescence, adulthood and old age) and describe the status of the brain at the selected phase. How may this shape behavior?

Option B: Sleep patterns change as we age. Select and examine a developmental phase (infancy, childhood, adolescence, adulthood and old age) and provide a description of the sleep patterns at the selected phase. How does your selected phase compare to those of other developmental phases?

Your initial post must be at least 300 words and use a minimum of one scholarly source located in the Ashford University Library or on Google Scholar that is cited and referenced according to APA style, as outlined in the Ashford Writing Center.

Guided Response: Review several of your classmates’ posts. Provide a substantive response to at least two of your peers in a minimum of 200 words. Respond to a post that examines a developmental phase different from the one you selected and one that examines the same phase. Discuss the extent to which you agree or disagree with the content of each post. Be sure that you cite scientific evidence to support your views.

Details:

Clearly identifying the independent and dependent variables in a study is a critical aspect of any research project. The dissertation is no different. This assignment will allow you to practice your skills in identifying research variables.

General Requirements:

Use the following information to ensure successful completion of the assignment:

  • In a study investigating the effects of humor on memory, Schmidt (1994) showed participants a list of sentences, half of which were humorous and half were non-humorous. Schmidt found that participants consistently recalled more of the humorous sentences than the non-humorous sentences, demonstrating that the use of humor increased participants’ recall of sentences.
  • Instructors will be using a grading rubric to grade the assignments. It is recommended that learners review the rubric prior to beginning the assignment in order to become familiar with the assignment criteria and expectations for successful completion of the assignment.
  • Doctoral learners are required to use APA style for their writing assignments. The APA Style Guide is located in the Student Success Center.
  • This assignment requires that at least two additional scholarly research sources related to this topic, and at least one in-text citation from each source be included.

Directions:

In as essay of 250-500 words, thoroughly address the following items:

  1. Define the term independent variable and identify the independent variable for this study.
  2. Describe the scale of measurement used for the independent variable.
  3. Define the term dependent variable and identify the dependent variable for this study.
  4. Describe the scale of measurement used for the dependent variable.
  5. Provide an example of a simple study using Schmidt (1994) as a model. State the purpose of the research (Schmidt’s purpose was to examine the effects of humor on memory), the research question (Schmidt’s research question was: What are the effects of humor on memory?), the independent variable, and the dependent variable for your study.

A Brief Description Of Two Emerging Issues Confronting The Psychology Profession

/in /by

As the psychology profession evolves, new issues continue to arise. Advances in technology influence the way professional psychologists practice, which creates additional considerations such as patient privacy. As the world becomes more globally connected, additional ethical and multicultural issues emerge. As practitioners, professional psychologists must follow both professional and government regulations, both of which are continually changing. At times, these regulations may seem to act as barriers to effective practice. It is critical that psychologists know about these changes so they can accommodate them when necessary. It is your responsibility as a professional psychologist to examine emerging issues confronting the psychology profession and think about how they impact the future of the profession.

To prepare for this Discussion, visit the professional associations and organizations from Discussion 1 of this week. When you visit each website, pay particular attention to sections on the practice of psychology. These sections address the most pressing issues facing professional psychologists, both now and in the future

Assignment 2: LASA 1: Case Studies Presentation

By Wednesday, November 25, 2015, create a Microsoft PowerPoint presentation to educate a group of medical students participating in their grand rounds. There should be at least ten slides in your Microsoft PowerPoint as well as a title slide and a slide listing all your sources for creating this slideshow. You should also create speaker notes for each slide of your presentation, which include the main talking points for the topic addressed on the slide. Save the presentation as

In order to create your slideshow, review the two case studies and then answer the questions following each case study:

Case Study 1: Isaac is a fifty-nine-year-old man. Several months ago, he noticed a slight tremor in his hands. He assumed this to be a normal consequence of aging. The tremor, however, gradually worsened, along with some muscular stiffness and slowness in initiating movement. The tremor was more pronounced when he was not voluntarily moving. Isaac was referred to a neurologist, who diagnosed him with Parkinson’s disease. After visiting the neurologist, Isaac and his family ask you to further explain this disorder. Isaac also asks about L-dopa as a treatment—the neurologist had mentioned L-dopa as an effective medication but had instead prescribed selegiline:

  • What are the symptoms of Parkinson’s disease?
  • What are the possible causes? Be sure to discuss both hereditary and environmental factors thought to contribute to this disease.
  • What parts of the brain does this disease affect?
  • Why do you think the neurologist prescribed selegiline instead of L-dopa?

Case Study 2: Sabrina is a twenty-seven-year-old woman who recently underwent a corpus callosotomy. Initially after surgery, when given a verbal command, Sabrina demonstrated marked apraxia of the left hand. However, the extent of this issue diminished over time. Answer the following questions about this client:

  • What disorder was most likely being treated by this operation, and how is the surgery performed?
  • In what way is the surgery expected to help Sabrina?
  • What are the risks and benefits of the surgery? Compare these to the risks and benefits of an alternative treatment. If the decision were yours, which would you recommend? Explain your decision.
  • What was the cause of the apraxia?
  • What does the reduction in apraxia symptoms tell us about hemispheric specialization?

For this assignment and all Dropbox assignments, you are required to cite, at a minimum, the online course and the textbook for the course. Additional sources are welcome. Scholarly sources are preferred and can be found in the Argosy University online library. For reputable web sources, look for .gov or .edu sites as opposed to .com sites. Do not use Wikipedia.
