Prospective memory, memory to perform future intended actions, is an important component of independent living for older adults. The current study examined prospective memory performance in 120 adults (Young-Old; 45-64 years old and Old; 65 - 87 years old) using Virtual Week (Rendell & Craik, 2000; Rendell & Henry, 2009). Virtual week was used to assess performance for regular and irregular event based, regular and irregular time based, and time check prospective memory tasks. Prospective memory performance under conditions of stereotype threat, stereotype boost, and a neutral condition was also examined. Stereotype threat occurs when individuals fear their behavior will confirm a negative opinion regarding one’s in-group. Older adults completed fewer prospective memory tasks compared to participants in the Young-Old group. No effect of stereotype condition on completion of prospective memory tasks was observed. The implication that stereotype threat may influence memory systems differently, as well as the possible role of the positivity effect on performance is considered.

Stereotype threat is defined as a sociopsychological threat evoked by an evaluative situation in which a negative stereotype about one's group could be confirmed (Steele, 1997). While the deleterious effects of stereotype threat have been demonstrated numerous times in laboratory settings (McKay, Doverspike, Bowen-Hilton, & Martin, 2002; Ngyuen & Ryan, 2008; Spencer, Steele & Quinn, 1999; Steele & Aronson, 1995), generalization to actual testing situations has been limited (Stricker & Ward, 2004). The current study sought to increase ecological validity by examining stereotype threat among racial/ethnic minority students undergoing assessment using the Wechsler Adult Intelligence Scale-IV (WAIS-IV) without explicit priming. Another aim was to reduce stereotype threat by emphasizing the malleability of intelligence, as recommended by previous researchers (Aronson, Fried, & Good, 2002; Good, Aronson, & Inzlicht, 2003). Additionally, the relationship of ethnic identity to stereotype threat and test performance and the role of anxiety, a proposed mechanism of stereotype threat, were examined. Participants were also interviewed about their experiences of stereotype threat using a phenomenological approach. A 2(condition) x 3(race/ethnicity) experimental design was used, and 138 college students were randomized to the control or malleability conditions. Due to manipulation failure, the hypothesis that African and Latino American students would experience less stereotype threat and perform better on the WAIS-IV in the malleability condition could not be tested. Qualitative findings suggested that while participants endorsed perceptions of stereotype threat in general societal settings, they did not report stereotype threat while undergoing the WAIS-IV. The hypothesis that ethnic identity moderates the relationship between stereotype threat and performance received mixed support: ethnic identity-affirmation interacted with perceived stereotype threat on Digit Span, but all other interactions were nonsignificant. Lastly, the hypothesis that anxiety mediates the relationship between perceived stereotype threat and WAIS-IV performance was not supported. However, post-hoc analyses suggested that perceived stereotype threat mediates the relationship of anxiety and WAIS-IV performance. Correlational results revealed that perceived stereotype threat and stereotype vulnerability were related to WAIS-IV scores. In addition, students of color reported greater test and state anxiety than their European American counterparts. Implications for researchers, test administrators, and admissions officers are discussed. / text

The purpose of this dissertation is to explore how stereotype threat impacts women and minorities within the College of Engineering. Within this study, I present a mixed-methods study that begins with an exploratory qualitative study into an sequential explanatory study. The purpose of the first study, Manuscript 1, was to identify common barriers present to women in engineering that negatively impact their motivations within engineering. During the analysis of this data, stereotype threat emerged as a common theme which lead to a literature review and subsequent explanatory study. A quantitative study, using Picho and Brown’s Social Identities and Attitudes Scale, was conducted to help pin point which groups on campus (i.e. women, men, and racial groups plus their intersections) were most impacted by stereotype threat (Manuscript 2, Chapter IV). The instrument also divides stereotype threat amongst six different constructs which allowed insight into specifically which types of stereotypes persist within engineering. Using the data collected from the 137 participants, I was able to identify that women are the most at risk for stereotype threat across 4 of the constructs in the instrument. Using the information from the SIAS instrument, I developed a focus group protocol and conducted 4 different focus groups with 8 different participants to gather data on what ways these negative stereotypes persist and interfere with women’s motivations within engineering (Manuscript 3, Chapter V). The implications of this research is then utilized to formulate proposed solutions to increase diversity and inclusivity within engineering.

It is well documented that some populations experience higher rates of certain diseases. While researchers have explored factors contributing to health disparities, attention has turned to the influence of social factors. For instance, stereotype threat has recently been applied to the health care setting in order to explain growing health disparities (e.g., Aronson et al., 2013). Health care stereotype threat (HCST) may arise when patients become aware that a negative health stereotype exists about a group or groups with which they identify, thus negatively impacting their utilization of health care services. Furthermore, patients with multiple marginalized identities have unique experiences of stereotyping and discrimination within the health care system. The purpose of the current study is to address Abdou et al.’s (2016) recommendation that researchers examine health care stereotype threat among individuals with multiple marginalized identities. The present study identified patients with a chronic illness and multiple marginalized identities including: (a) identifying as Black, (b) being considered overweight by medical community, and/or (c) identifying as Lesbian, Gay, Bisexual, and Transgender (LGBT). These identities were chosen based on research indicating that physicians hold implicit bias attitudes towards and stereotypes about these groups (e.g., Blair et al., 2013; Chapman et al., 2001; Sabin et al., 2009). I utilized qualitative research methodology to contextualize patients’ experiences of stereotyping in a health setting. In person, semi-structured interviews were conducted with eight patients. During the interview process, four major categories and 22 sub-level categories emerged. Grounded theory methodology (Corbin & Strauss, 2008) was used to analyze the data. The results of the study revealed a complex relationship between negative experiences with a provider (i.e., dismissive communication and perceived stereotyping) and health care utilization. Patients’ negative experiences with providers made it more difficult for patients to continue engaging in care. Systemic barriers as well as level of coping and social support influenced patients’ perception of stereotyping and discrimination. Level of support from other providers and use of coping skills also determined the extent to which patients continued to utilize available health care in the face of discrimination. Implications for future research and clinical practice are delineated.

Science thrives when there is a continuous flow of new ideas and diverse generations of scholars contributing to the field. Although academic institutions aim to encourage diverse viewpoints, a culture of atheism among university faculties may unwittingly be contributing to an anti-religious atmosphere. The main focus of this dissertation is to investigate people’s attitudes toward religious individuals, and how these attitudes affect the religious believers’ mental health and academic performance. Study 1 (N = 899) found that people tend to explicitly report that religious believers have lower intelligence, but to implicitly associate them with higher intelligence. Although this is the case, faculty members, particularly those from secular institutions, did not have this implicit association and had the strongest congruity between their explicit and implicit intelligence preferences. Studies 2-3 showed that religious believers of diverse backgrounds reported experiencing overt and covert forms of religious bias, including biases related to their academic ability. Religious believers reported that they encountered more incidences of overt and covert forms of religious bias inside of higher education than outside of academia. Experiences of religious microaggressions significantly predicted higher rates of depression in Study 2 (N = 383) and marginally in Study 3 (N = 129). Finally, Study 4 (N = 169) found that compared to other religious groups, Christians were stereotyped to lack science competency. Study 5 (N = 237) demonstrated that these stereotypes applied to Christian college students and was at a comparable rate to how women are stereotyped to lack scientific competency and interest. Study 6 (N = 93) demonstrated that these negative stereotypes cause Christian college students to become less interested in and identify less with sciences. They also caused Christian college students to underperform on science-relevant tasks, especially those students with a stronger religious identity (Study 7; N = 90). These studies reveal that stereotypes play a key role in pushing religious believers out of science. Implications and future directions in the representation of religious believers in academia and science fields are discussed. This dissertation includes previously published and unpublished co-authored material. / 2021-01-11

The present research examined how interactions with sexist men can trigger stereotype threat among women, undermining their engineering and mathematical performance. Chapter 1 provides an overview of the literatures on sexism and on stereotype threat. Chapter 2 validates a subtle sentence completion measure of sexism. In Chapter 3, male engineering students who scored highly on this sexism measure behaved in a dominant and sexually interested way towards an ostensible female classmate. In Chapter 4, female engineering students who interacted with such sexist men, or with confederates trained to behave in the same way, performed worse on an engineering test than women who interacted with nonsexist men. Chapter 5 conceptually replicated this finding and showed that women’s underperformance did not extend to an English test, an area in which women are not negatively stereotyped. Furthermore, interacting with sexist men lead women to suppress concerns about gender stereotypes, an established mechanism of stereotype threat. Chapter 6 discusses the implications for stereotype threat and for addressing barriers to women’s performance at school and in the workplace.

The purpose of this study was to develop and validate a series of the ¡§Gender Stereotype Threat Inventory¡¨(GSTI) of junior high school students in science classroom. The GSTI was included three scales: domain indentification, gender stereotype and learning environment. The GSTI was conducted to a total of 640 8th graders in Kaohsiung city. Results of the study were employed for internal consistency analysis, confirmatory factor analysis, Rasch modeling analysis, as well as the multiple invariance approach to test its reliability and validity. The result manifested that each scale had reasonable coefficient Cronbach alpha ranging from .73 to .85 and the overall model fit indices indicated that model fitted the oberserved data and had cross-validation. Finally, the results of gender stereotype threat in science classroom and implications for using the GSTI inventory in future research are presented.

The present study compared the effectiveness of different mentoring programs at reducing feelings of stereotype threat experienced by women in science, technology, engineering, and math (STEM) fields. Stereotype threat refers to the extra pressure a person feels to disprove a negative stereotype that applies to him or her. Because stereotype threat has been found to undermine performance and interest in stereotyped domains, it may be a key factor contributing to female underrepresentation in STEM fields. Mentors and proteges were placed in either a stereotype threat reduction condition in which mentors and proteges were encouraged to participate in discussions designed to reduce stereotype threat, an academic condition in which mentors and proteges were encouraged to discuss academic goals and challenges, or a non-academic condition in which mentors and proteges were encouraged to discuss the challenges of balancing non-school commitments. It was hypothesized that mentoring that focused specifically on stereotype threat reduction would be the most effective in reducing stereotype threat and increasing intentions to remain in STEM fields. In addition, it was hypothesized that stereotype threat reduction mentoring would be the most effective at increasing beliefs in an incremental theory of intelligence (i.e., the belief that intelligence can be developed through hard work) and decreasing beliefs in an entity theory of intelligence (i.e., the belief that intelligence is innate and is unalterable). Mentors were 36 male and 74 female upper-level STEM college students and proteges were 137 female lower-level STEM college students. Participants met online for 30 minutes, once per week, for 3 weeks. Results indicated that both mentors and proteges in the stereotype threat reduction mentoring condition reported feeling less stereotype threat in their STEM classes than mentors and proteges in the other mentoring conditions. Additionally, the frequency in which self-theories were discussed in the mentoring sessions partially mediated the effects of the stereotype threat reduction condition on proteges' feelings of stereotype threat in their STEM classes. Mentors and proteges in the stereotype threat reduction mentoring condition also reported endorsing incremental theories of intelligence more and endorsing entity theories of intelligence less than mentors and proteges in the other conditions. In summary, the present study's findings suggest that in order maximum stereotype threat reduction to occur in a mentoring relationship, mentors and proteges engage in activities and discussions designed to reduce stereotype threat. Given that prior research has found that decreased stereotype threat, decreased entity theories of intelligence, and increased incremental theories of intelligence are associated with greater interest and performance in STEM domains, the utilization of a stereotype threat reduction mentoring program can help address the underrepresentation of women in science, technology, engineering, and math related fields.
