The “filter bubble” has been a heated discussion topic since several years ago. In addition to possible algorithmic contribution to this phenomenon, people’s selective exposure tendency may be another primary cause of the “filter bubble” on social media. Prior research indicates that, under the influence of selective exposure tendency, people tend to perceive pro-attitudinal news as more credible than counter-attitudinal news, with strong partisans more likely to be affected. The proposed thesis seeks to examine whether the perceived credibility of a news source and story on social media is influenced by selective exposure and strength of partisanship. Through an experimental study via Amazon’s Mechanical Turk, 468 participants chose or were assigned to read an ostensible news story from a social media feed with the news source and ideological slant varied between participants. The results showed that people reported higher perceived source and story credibility when the source and stories were pro-attitudinal (consistent with their political ideology) as opposed to counter-attitudinal, regardless of participants’ age, race, perceived credibility of news from social media, in general, and strength of partisanship. However, contrary to the hypotheses, selective exposure behavior (i.e., choosing a preferred news source before reading a news story) did not affect credibility perceptions when participants read counter-attitudinal news from a pro-attitudinal source. Last, strength of partisanship did not moderate the influence of selective exposure on credibility perceptions. In sum, this study suggests that although selective exposure tendency may affect people’s credibility perceptions and contribute to “filter bubbles,” the impact of selective exposure behavior may be overestimated in terms of perceived source and story credibility of news on social media.

This thesis project had three key components. First, we performed an extensive literature review of different types of feminist theories to better understand the scope of their definitions. We also reviewed several articles that examined how women, especially Latinas, seek to understand and negotiate their identity as feminists. Second, we conducted qualitative interviews with Latina college women in which they shared their college experiences, their thoughts on feminism, and how they believe the cultural values they were brought up with play a role in both. Finally, we developed a 12-minute documentary film containing excerpts from participants’ interviews that reflected a number of core themes. We invited participants to view the documentary and contribute to a post-film conversation with interested faculty members and students. The interactive post-film conversation served as a reflection and expansion of the themes in the film and challenged those that participated to explore avenues of resolution through family and communication.
The motivation for this project came from a place of reflection for what it means to be a feminist and Latina and how to navigate the values of both without compromising one over the other. After personally contemplating the meanings and process without coming to a concrete understanding, we were prompted to branch out and engage other Latina college students in a conversation about what it means for them, what unique challenges they may be facing, and how they may be seeking to answer questions surrounding their identity.

Social scientists from many disciplines have examined trust, including trust between those with different religious affiliations, emotional antecedents of trust, and physiological correlates of trust. However, little is known about how all of these factors intersect to shape trust behaviors. The current study aimed to examine physiological responses while individuals engaged in a trust game with a religious in-group or out-group member. Participants were randomly assigned to one of four conditions in which they were presented with the target’s profile before playing the game. In each of the conditions the target was described as either Catholic or Muslim and as someone who engaged in either costly signaling or anti-costly signaling behavior. In addition to assessing the amount of money invested as a behavioral measure of trust, physiological responses, specifically cardiac interbeat interval (IBI) and respiratory sinus arrhythmia (RSA), were measured. I hypothesized that when playing the trust game with a Catholic target as opposed to a Muslim target, Christian participants would (1) report being more similar to the target, (2) trust the target more, (3) invest more money in the target, (4) have a more positive outlook on the amount invested, and (5) show greater cardiorespiratory down-regulation, reflected by increases in IBI and RSA. Findings revealed that Christian participants reported greater similarity and showed a non-significant trend toward reporting a more positive outlook on (greater confidence in/satisfaction with) their investment decision when playing a Catholic versus Muslim target. Additionally, Christian participants who played an anti-costly signaling Catholic target showed greater cardiorespiratory down-regulation (increases from baseline for IBI, reflecting slower heart rate, and increases in RSA) than Christian participants who played an anti-costly signaling Muslim target. Results from this study echo previous findings suggesting that perceived similarity may facilitate trust. Findings also are consistent with previous research suggesting that religious ingroup or outgroup membership may not be as influential in shaping trust decisions if the trustee is costly signaling; for anti-signaling, however, cardiorespiratory down-regulation to a religious ingroup member may be apparent. These physiological signals may provide interoceptive information about a peer’s trustworthiness.

The outcomes of parental divorce on offspring has been extensively examined in

previous research. How parental divorce predicts gender attitudes and behaviors in offspring, however, is less studied. More specifically, research suggesting when the divorce occurs on young adult offspring attitudes and behaviors has not be reviewed to my knowledge in previous literature. Several instruments were used in the current paper to address how gender-typed attitudes and behaviors are predicted by parental divorce occurring between the age groups of birth-6, 7-12, or 13 and older in relation to individuals from intact families. Participants were 202 individuals, where 75 experienced a parental divorce or separation sometime in their life. Gender attitudes were assessed through the Pacific Attitudes Toward Gender Scale, Attitudes Toward Divorce Scale, Attitudes Toward Marriage Scale, and a scale created for this study on dating expectations. Gender behavior was assessed through scales created for this study: current occupation or major, number of romantic relationships, number of friends with benefits, number of one night stands, safe sex use, and future plans on marrying or having children. The Personal Attributes Questionnaire was also used to determine participants’ self-report of their masculinity or femininity. The results suggest parental divorce occurring between 7 and 12 years predicted more egalitarian gender attitudes compared to other groups. Gender attitudes also partially mediated the relationship between the timing of divorce and gender behavior in an exploratory analysis, although this was only significant for men. Finally, it was found that men whose parents divorced tend to report less safe sex, whereas women from divorced families tend to report more one night stand

relationships than those from intact families. The data were partially supported by previous research of timing, where those whose parents divorced tend to show more egalitarian gender attitudes and behaviors.

Long-term results of dietary weight loss interventions are not promising, with rates of weight loss maintenance at a mere 20%. Psychological factors related to weight maintenance include setting unrealistic weight goals, poor problem-solving skills, low self-efficacy, dichotomous thinking, and external locus of control. The ability to maintain a stable bodyweight over time has been associated with optimal health outcomes, lower stress levels, and higher general well-being. Dichotomous thinking has been associated with overeating and increased bodyweight. Cognitive restraint, disinhibition, and hunger are three dimensions of human eating behavior that appear to be important to understanding weight loss maintenance. Individuals who attempt to maintain their bodyweight via dietary restraint mechanisms are more susceptible to excessive eating episodes. Disinhibition has been found to be the strongest predictor of weight gain, while the research on the association between hunger and bodyweight is mixed. This study sought to evaluate the relationship between dichotomous thinking toward food and various eating behaviors (binge eating, cognitive restraint, disinhibition, and hunger). A multiple regression analysis revealed that binge eating, cognitive restraint, disinhibition, and hunger were each significant unique predictors of higher body mass index (BMI). Higher levels of hunger predicted lower BMI, controlling for cognitive restraint, disinhibition, and binge eating. Mediation analyses revealed that dichotomous thinking mediated the relationships between binge eating and BMI, cognitive restraint and BMI, and disinhibition and BMI. Further analysis revealed that binge eating mediated the relationship between dichotomous thinking and BMI, indicating that thinking of food in black-and-white could lead to higher rates of binge eating, and the excess calorie consumption could lead to increased BMI. The study findings suggest that a strong focus should be made to promote a more flexible attitude toward food in an effort to improve weight loss maintenance in the population.

There are some factors that have been used to explain why the presence of a calling (i.e., “an approach to work that reflects the belief that one's career is a central part of a broader sense of purpose and meaning in life and is used to help others or advance the greater good in some fashion” (Duffy & Dik, 2013, p. 429) reduces work stress and its potential negative outcomes, such as absenteeism, job performance and productivity, work-related accidents and overall employee health. The effect of problem-focused coping, however, remains largely untested as a potential mediator in this relation. The present study was conducted to quantitatively test whether problem-focused coping would mediate the relation between having a calling to work and perceived work stress in zookeepers. Participants were recruited through an online survey. They responded to questionnaires regarding calling, problem-focused coping, and work stress. Using hierarchical regression analyses, it was found that problem-focused coping partially mediated the relation between presence of a calling and perceived work stress. Specifically, having the presence of a calling to work predicted greater problem-focused style of coping, which, in turn, led to lower perceived work stress. Future directions for research were discussed.

Juror impartiality is necessary for a fair and just legal system, but is true juror impartiality

realistic? The current study investigated the role of implicit and explicit social-cognitive biases in jurors’ conceptualizations of insanity, and the influence of those biases in juror verdict decisions. It was hypothesized that by analyzing the role of implicit and explicit biases in insanity defense cases, jurors’ attitudes towards those with mental illnesses and attitudes towards the insanity defense would influence jurors’ final verdict decisions. Two hundred and two participants completed an online survey which included a trial vignette incorporating an insanity defense (adapted from Maeder et al., 2016), the Insanity Defense Attitude Scale (Skeem, Louden, & Evans, 2004), Community Attitudes Towards the Mentally Ill Scale (Taylor & Dear, 1981), and an Implicit Association Test (Greenwald et al., 1998). While implicit associations concerning mental illness and dangerousness were significantly related to mock jurors’ verdicts, they no longer were when explicit insanity defense attitudes were added to a more complex model including all measured attitudes and biases. Insanity defense attitudes were significantly related to jurors’ verdicts over and above attitudes about the mentally ill and implicit biases concerning the mentally ill. The potentially biasing impact of jurors’ insanity defense attitudes and the impact of implicit associations about the mentally ill in legal judgments are discussed.

Delay discounting is the decline in the present value of a reward with delay to its receipt. (Mazur,1987). The delay discounting task is used to measure delay discounting rate, which requires the participants to choose between two options: one involves immediate delivery of a reward, and other involves delivery after a delay, and the immediate rewards are adjusted in value until the subject feels there is no difference between the immediate and the delayed reward. Some previous studies (Robles and Vargas, 2007; 2008; Robles et al., 2009) found that the order of presentation of the immediate rewards (ascending or descending) significantly influenced the estimated delay discounting rate, which is known as the order effect. Uncertainty about the future and impulsivity could explain delay discounting behavior. The purpose of this study was to explore the order effect in delay discounting assessment. The current study found that the order effect in the delay discounting task can be explained by risk aversion, loss aversion and impulsivity. In the current study, the two kinds of fixed procedure (ascending and descending), and the titrating delay discounting task were used to estimate the degree of delay discounting. Also, two gambling tasks were applied to measure risk and loss aversion indices. The BIS-11 scale was used to assess the level of trait impulsivity. The results indicated that impulsivity biases individuals to choose the immediate small reward rather than the large delayed reward, resulting in lower area under the discounting curve (AUC) when estimated with the ascending-sequence delay discounting task. Also, impulsivity moderated the relationship between loss aversion and AUC estimated with the descending-sequence delay discounting task.

Numerous studies have established that during the transition to parenthood couples experience changes within their relationship as well as in their overall mental health. The present study examines these changes specifically through conflict interactions. The author proposes the more conflict that occurs within a relationship, the lower each individual's self-esteem; the lowered self-esteem then leads to signs of depression. The present study's analysis consisted of two primary aims: 1) examine the association between romantic relationship conflict and mental health by using a proposed mediational pathway, in which self-esteem explains the connection, and 2) explore gender differences. The study aims were examined using secondary data analyses of Dr. Kristin Mickelson's study on couples transitioning to parenthood (Baby TIME Study). Results varied by conflict type as well as gender. When conflict was measured by perceived negative spousal interactions, results showed that the proposed mediational pathway was significant for men, but not for women. When conflict was measured by frequency of spousal arguments, results showed that the proposed mediational pathway was significant for women, but not for men. Furthermore, the results from this analysis indicate that during the transition to parenthood, men and women are affected by conflict differently in regards to their self-esteem and further their reported levels of depression.

The thesis examines the intricacies involved with the language barriers experienced by patients with Limited English Proficiency (LEP) in medical encounters in the U.S. It examines the evidence showing the impact that language barriers have on both the quality of care and the satisfaction with care experienced by patients with LEP. It also presents an overview of the laws regulating these interactions and its limitations. It further examines the pros and cons of the use of interpreters as the primary strategy developed to operationalize these regulations, including lack of funding for medical interpreters, lack of appropriate training and certification, and language diversity. Additionally, language barriers are examined in the context of cultural differences that permeate all social encounters. One key finding of this review is that communication problems are not only an issue for the LEP population, providing health-care for all patients involve sharing information among multiple health-care providers, patients and their families. However, it is well-documented that LEP makes health-care communication exponentially more challenging. The work concludes with some possible solutions to improve the quality of care and satisfaction of patients with LEP.
