Throughout this unit, you have learned about various research methods that are used by psychologists. For this assignment, you must choose three of the six scenarios listed below. Elena is a psychologist interested in understanding the impact of a sense of control on stress in humans. She brings in students from around campus and gives them a number of choices (increasing sense of control) before exposing them to a very difficult math test. She brings in another group of students and does not give them any choices before giving them the math test. She uses the scores earned by the two groups to see if those students given choices before the test do better than the students who did not get choices. Maxim is working with Joaquin in a counseling situation. Joaquin is a resident of the local jail, having been found stealing pastries from a bake shop. When caught, Joaquin claimed that the devil told him to do it and that he had done far worse things in the past. Maxim visits with him and makes notes about what he learns about Joaquin each time they are together. Glynnis is interested in understanding how people handle confrontation. She hangs out in a store near the customer service counter unobtrusively watching the agents at the desk. She records if they respond with passive aggressiveness, kindness, or anger. Gigi is a student in the marketing department. She wants to understand more about what attracts people to certain products. She creates a document with pictures of cereal boxes and asks people to rate which box they would be most attracted to when searching for a cereal. She then gathers information about their age, income, profession, and gender. Breck is interested in studying personal space and relationships. He gathers a number of students who are strangers, acquaintances, close friends, or in romantic relationships. He brings them into a classroom and asks them to begin a conversation with each other. He records the distance between the individuals having the conversation. Lucretia works at a children’s hospital. Her responsibility is to ask children who are coming to the hospital for the first time to respond to a number of questionnaires that may help determine their anxiety, depression, and pain levels. After choosing three of the above scenarios, answer the following questions for each of your three scenarios. Which research method was used (case history, survey, naturalistic observation, psychological tests, laboratory observation, or experiment)? Identify the information in the scenario that supports your reasoning. What ethical guidelines would need to be followed to conduct this study? Which basic ideas behind early approaches in psychology most closely align with this method? Your responses to the questions above for the three scenarios must result in a combined total of at least two pages in length for the assignment, not including the title page. If outside sources are used, please adhere to APA Style when creating citations and references for this assignment. APA formatting, however, is not necessary.

Read "Can Technology Save Sears?" Case Study (see attached file). Textbook is also attached.Answer below questions. Please use this strategy when you analyze a case:Identify and write the main issues found discussed in the case (who, what, how, where and when (the critical facts in a case).List all indicators (including stated "problems") that something is not as expected or as desired.Briefly analyze the issue with theories found in your textbook or other academic materials. Decide which ideas, models, and theories seem useful. Apply these conceptual tools to the situation. As new information is revealed, cycle back to sub steps a and b.Identify the areas that need improvement (use theories from your textbook)Specify and prioritize the criteria used to choose action alternatives.Discover or invent feasible action alternatives.Examine the probable consequences of action alternatives.Select a course of action.Design and implementation plan/schedule.Create a plan for assessing the action to be implemented.Conclusion (every paper should end with a strong conclusion or summary)Writing Requirements:4–5 pages in length (excluding cover page, abstract, and reference list)Use APA format to complete the paper.Include proper citations and references in the paperUse the page break featureNo Plagiarism
