Order Description
Something important to notice
1.choose an article from the book is “Confronting perpetrators of prejudice, the inhibitory effects of social costs” and the author is Nicole Shelton and Rebecca Stewart Princeton University”.so you need to find two more related experiments or studies online(no news or opinion websites) MUST BE RESEARCH LITERATURE.
2. set up a hypothesis following the instruction.
3.create a graph of two variables (two main effects)
Assignment:
Your assignment is to describe your own original research: Introduction, Methods,
Results, Discussion, References. You are to generate an original hypothesis related to the
topic of the class, design an experiment designed to test the idea, and describe hypothetical
data in the results section.
Parameters of the assignment:
Length: Your poster should be 5 pages long, NOT including a title page or references.
Longer posters will be penalized 5 points for each page over limit.
o Title page:
o Pages 1-2: Background literature and hypothesis. Your background literature should consist of one reading from your syllabus or lecture, and two other empirical articles from the research literature (i.e., not news media, opinion websites, and the like). The background literature frames and gives rise to your hypothesis. Your hypothesis should be in the form of a statement (e.g., “I hypothesize that sleep deprivation will have detrimental effects on performance;” or “I hypothesize that sleep deprived individuals will perform more poorly on a cognitive task than individuals who are not sleep deprived”). Phrasing your hypothesis in the form of a statement ensures that you don’t end up with something untestable (e.g.,”Why are people so bad at remembering
information?”).
o Pages 2-3: Methods. This is where you tell us how you will test your hypothesis.
An experiment is required with 2 independent variables and 1 dependent variable. Each factor of your experiment should have two levels,1 so that you end up with a 2 X 2 design. Describe your design, materials, and procedure briefly. You do not have enough space to go into huge detail, so be judicious about what you write.
Show that you’ve been paying attention to all we have talked about with respect to good experimental design.
o Page 3-4: Results. Imagine that you have collected data. Present the results of your study in the form of at least one graph, and provide a description of the
findings as well. Describe hypothetical main effects or interactions, but there is no need to describe hypothetical statistical analyses (e.g, p values, t or F statistics). If you are having trouble with graphing software, draw your graphs (with care).
Your audience should be able to understand your data and results quickly. A
picture is worth a thousand words!
o Page 4-5: Discussion. Brief. What do the results tell us about the phenomenon you are trying to understand? What remains to be understood? What are some
1What are factors and levels? As we spoke about in class, for example, your professor’s 1999 dissertation
manipulated two factors: Target Race and Cognitive Load. The first factor, Target Race, had two levels:
White and Black , and Cognitive Load also had two levels: No Load versus Load.
future directions? Additionally, you must address at least one limitation of your
study.
o References (on a different page). These should be in APA style.
Brevity is key. Brevity, and the distillation of essential information, is important.
Go for simplicity and elegance. Your hypothesis and idea don’t have to be complicated.
Go for a straightforward hypothesis, and choose a neat, clean study to test your idea.
Revise. Don’t be fooled by the length of the assignment. An effective poster requires several drafts.
