Are there social situations in which one or more of the factors among your identities seem especially challenging or which provide support for you? If yes, can you think of social situations in which your “dominant” or “subordinate” identities play out in different ways – either challenging or supportive or both?

/in /by

Study question

Answer only ONE question from each section. Make sure you number each section in your answers. Each answer must be at least 100 words in length. You do not have to include a work cited page. Answers must make use of the reading/video as evidence.

Part One – Tatum “The Complexity of Identity”

  • Tatum describes identity as “complex” and made up of many different factors. As you think of your own identity, what are the racial, gender, sexual, class, religious and other factors that have shaped it? Do you mainly focus on one or two aspects of your identity or do you think of your identity as “complex” in real-life, everyday interactions? Can you describe some examples of how various factors in your own identity interact with each other?
  • How do you think that (what Tatum calls) your “dominant” and your “subordinate” identities have shaped your sense of yourself – as you are today? As your experiences have changed over time? Were there any personal experiences that stand out for you that made you especially aware of a “dominant” or “subordinate” identity?
  • Are there social situations in which one or more of the factors among your identities seem especially challenging or which provide support for you? If yes, can you think of social situations in which your “dominant” or “subordinate” identities play out in different ways – either challenging or supportive or both?

Part Two – Johnson’s “The Social Construction of Difference”

  • Johnson quotes James Baldwin’s statement that “No one is white before he/she came to America. It took generations, and a vast amount of coercion, before this became a white country.” Can you identify one or two examples of immigrants who became “White” in the US? Were they considered “White” before becoming Americans? Can you describe how that process of “whitening” happened?
  • On the other hand, for immigrants who did not become “White” when they came to American, how were they identified racially? Had that been their racial identity before the process of immigration?
  • Johnson makes the point that the “social construction of reality” applies to sexism and ableism as well as to racism and that these social constructions have no significance except to provide privilege for some and disadvantage for others. Can you provide examples of how systems of privilege and disadvantage – concerning race, or gender, or any other system of advantage and disadvantage – may have changed over time, as the “social construction of reality” itself changed?
  • Johnson distinguishes between “diversity”/“difference” (“difference” need not imply inequality) and “privilege”/“oppression” (in which inequality is rationalized or justified by differences). Can you think of examples you’ve personally observed of “differences” that you have observed or experienced that do not convey inequality? Can you think of examples you’ve observed or experienced of “differences” that are used to justify privilege and oppression?

Part Three – Sue’s “Microaggressions, Marginality, and Oppression”. Make sure you also use this video on Microaggressions to support your answer.

https://www.youtube.com/watch?v=hDd3bzA7450 (Links to an external site.)

  • Have you observed or overheard any of Sue’s examples of microaggressions in your neighborhoods or schools or families? Have you experienced them yourself? How does the accumulation of multiple microaggressions, day after day, make the person experiencing them feel?
  • Have you tried to interrupt a microaggression? Can you provide an example of interrupting microaggressions successfully?
  • Looking ahead to the next section, where Young describes oppression as the result of the “unquestioned norms, habits, and symbols … [of] normal processes of everyday life”: Can you give examples of how Sue’s approach to microaggression might illustrate Young’s description of oppression?

Part Four – Young’s “Five faces of oppression.”

  • Here’s how Young defines oppression: “Its causes are embedded in unquestioned norms, habits, and symbols, in the assumptions underlying institutional rules and the collective consequences of following these rules … in short, the normal processes of everyday life.” What examples of “the normal processes of everyday life” have you experienced or observed that fit Young’s definition of oppression? Why do you think these normal processes of everyday life are not questioned or resisted?
  • Young offers a different explanation of oppression from the explanation in Bell, Adams, and Zúñiga. Do you find it useful to have two different explanations oppression? Do they clarify different aspects of a complicated social system?

  1. Where are your eyes?

The objectifying gaze, often referred to as “ogling” or “checking out,” can have many adverse consequences. A group of researchers used eye-tracking technology to better understand the nature and causes for this gaze. They asked 29 women and 36 men to look at images of college-aged women. Each woman had the same clothes and neutral expression but varied in body shape (ideal, average, and below average). Prior to looking at the images, each participant was told to focus on either the appearances or personalities of the women. Here is a summary of the amount of time (in milliseconds) the eyes focused on the chest of the women:

  1. Plot the means. Do you think there is an interaction? Explain your answer.
  2. Do you think the marginal means would be useful for understanding the results of this study? Explain why or why not.
  3. The researchers broke these results down further using body shape as a third factor. Describe why the inclusion of this factor complicates the analysis. In other words, why is this not a standard 2×2×3 experiment?

 

 

 

  1. A study reported the following results for data analyzed using a two-way ANOVA at the 5% significance level:
  2. What can you conclude from the information given?
  3. What additional information would you need to write a summary of the results for this study?

 

  1. 3. The effects of two stimulant drugs. An experimenter was interested in investigating the effects of two stimulant drugs (labeled A and B). She divided 25 rats equally into five groups (placebo, Drug A low, Drug A high, Drug B low, and Drug B high) and, 20 minutes after injection of the drug, recorded each rat’s activity level (higher score is more active). The following table summarizes the results:
  2. Plot the means versus the type of treatment. Does there appear to be a difference in the activity level? Explain.
  3. Is it reasonable to assume that the variances are equal? Explain your answer and, if reasonable, compute sp.
  4. Give the degrees of freedom for the F statistic.
  5. The F statistic is 2.64. Find the associated P-value and state your conclusions.

 

 

  1. The National Survey of Student Engagement found that 87% of students report that their peers at least “sometimes” copy information from the Internet in their papers without reporting the source. Assume that the sample size is 430,000.
  2. Find the margin of error for 99% confidence.
  3. Here are some items from the report that summarizes the survey. More than 430,000 students from 730 four-year colleges and universities participated. The average response rate was 43% and ranged from 15% to 89%. Institutions pay a participation fee of between $3000 and $7500 based on the size of their undergraduate enrollment. Discuss these facts as possible sources of error in this study. How do you think these errors would compare with the error that you calculated in part (a)?

 

  1. 5. Food neophobia is a personality trait associated with avoiding unfamiliar foods. In one study of 564 children who were two to six years of age, the degree of food neophobia and the frequency of consumption of different types of food were measured. Here is a summary of the correlations:

Perform the significance test for each correlation and write a summary about food neophobia and the consumption of different types of food.

 

 

BONUS:

Laptops and other digital technologies with wireless access to the Internet are becoming more and more common in the classroom. While numerous studies have shown that these technologies can be used effectively as part of teaching, there is concern that these technologies can also distract learners if used for off-task behaviors.

In one study that looked at the effects of off-task multitasking with digital technologies in the classroom, a total of 145 undergraduates were randomly assigned to one of seven conditions.12 Each condition involved performing a task simultaneously during lecture. The study consisted of three 20-minute lectures, each followed by a 15-item quiz. The following table summarizes the conditions and quiz results (mean proportion correct):

  1. For this analysis, let’s consider the average of the three quizzes as the response. Compute this mean for each condition.
  2. The analysis of these average scores results in SSG=0.22178 and SSE=2.00238. Test the null hypothesis that the mean scores across all conditions are equal.
  3. Using the means from part (a) and the Bonferroni method, determine which pairs of means differ significantly at the 0.05 significance level. (Hint: There are 21 pairwise comparisons, so the critical t-value is 3.095. Also, it is best to order the means from smallest to largest to help with pairwise comparisons.)
  4. Summarize your results from parts (b) and (c) in a short report.

Using accurate terminology, describe what makes “Artist 47”, “Artist 47”.
