Research and Critique an Experimental Study

Prior to beginning work on this assignment, be sure to have read all the required resources for the week.

Find an experimental research study on the topic chosen in Week One for your Final Research Proposal. You may choose to include an experimental study which was included in the literature review you used in the Week One assignment by searching the reference list for experimental research studies on the topic. However, it is also acceptable to find and include an experimental research study on the topic that is not included in that literature review.

Identify the specific experimental research design used in the study. Summarize the main points of the experimental research study including information on the hypothesis, sampling strategy, research design, statistical analysis, results, and conclusion(s). Evaluate the published experimental research study focusing on and identifying the specific threats to validity that apply to the chosen study. Explain whether or not these threats were adequately addressed by the researchers. Describe how the researchers applied ethical principles in the research study. Assumptions About Human Behavior Select one of the schools of thought from the readings for this week (physiology, experimental psychology, voluntarism, structuralism, functionalism, Gestalt psychology, and other early approaches). Discuss your chosen school of thought in terms of these four attributes: 1. Principles: Rules and standards associated with the school of thought. 2. Values: Core beliefs, ideals, and priorities that distinguish this school of thought from others. 3. Subject Matter: Content, the issues focused on by practitioners of this school of thought. 4. Research Methods and Other Applied Methodologies: Questions asked and problems solved by those using this school of thought. Identifying Your Assumptions Your initial post in this discussion has two parts; be sure to address both of them. First, describe your own assumptions about human nature and behavior, using the questions below to help clarify your theoretical assumptions. Next, choose from the schools of thought presented in the multimedia piece, Introduction to Schools of Psychological Thought. Is there one or more school of thought that seems to match your own assumptions? How? Be specific and use the four attributes outlined in this unit’s Assumptions About Human Behavior discussion to discuss how your personal theory aligns with a school of thought. In preparing your response, you may use these questions to help define your existing assumptions: • What is the importance of biology? How much animal heritage remains in humans? • Are people basically good, bad, or neutral? • Is human behavior determined by past events and training, or by genetics? Is there free will? • How much influence is exerted by nature and by nurture? • How are the mind and body related? • What is the relative importance of feelings, thoughts, and actions in human behavior? How should we go about finding answers to questions about human beings?
