Item Studying the Effects of Colors Within Virtual Reality (VR) on Psychological and Physical Behavior(2024) Fabian, Ciara Aliese; Aston, Jason; Library & Information Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Color theory is an important aspect of today's world, especially when consideringuser design, technology, and art. The primary objective of this thesis is to examine how the color groups, warm and cool, affect individuals psychologically and physiologically. While combining technological advancements, physiological methods, and psychological analyses, I will try to discover the emotional associations with specific color groups and determine the psychological and physiological impact of color groups on individuals. I hypothesize that warm colors will increase heart rate and skin conductance response, which will directly correlate to emotions of stress and excitement, and cool colors will decrease heart rate and skin conductance, which is associated with the emotions of calmness and positivity. This study demonstrated that the two-color groups exhibited a notable influence on heart rate. Using the skin conductance response method yielded unanticipated results in comparison to prior research. Prior studies have shown that there is a relationship between heart rate and skin conductance response, and therefore, if one increases, then the other should also increase. This study found that when the heart rate increased, many participants experienced a decrease in skin conductance response, showcasing a contrast in physiological reaction. Furthermore, the study demonstrated a correlation between physiological changes, such as heart rate variations, and corresponding changes in participants' psychological behavior.Item IN THE NAME OF CULTURE: THE POLITICS OF CELEBRATION IN THE MULTICULTURAL CIVIL SPHERE(2018) Richer, Zach; Fisher, Dana R; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)A common barrier to the civic integration of immigrant and minority groups is the suite of symbolic classifications that structure everyday relations in diverse societies and set standards for inclusion and exclusion in shared public spaces. Although the regulatory norms governing the civil sphere are increasingly understood to be constituent elements of social power, they are not frequently seen as targets of collective action. As they are held in private attitudes and expressed spontaneously in everyday conduct, these forms of symbolic power do not easily lend themselves to political solutions. What form might a contestation of symbolic exclusion take? This dissertation examines the strategy of celebratory civics pursued through an annual series of 23 free public cultural festivals organized throughout the year by ethnic community organizations in partnership with the city of Seattle. Participating groups ii describe the dominant civil sphere as a place where opportunities for public deliberation about ethnic minority issues are scarce and ineffective, while confrontational protests antagonize potential allies and produce negative associations with minority cultural groups. They are skeptical that traditional civic action targeting policymakers is adequate to addressing discriminatory practices where they are most intimately felt, in the everyday conduct of social life in diverse societies. Through positive emotional appeals directed towards unfamiliar audiences unlikely to engage with them in everyday life, festivals aim to establish “common ground” on which to displace ethnic and racial stereotypes and make viable alternative ways of affirming civic belonging. Based on interviews with ethnic community organizations, their municipal sponsors, and festival visitors, surveys demonstrating the audience profile and expectations for the event, and a year of ethnographic observation at planning meetings and public festivals, this dissertation explores the promise and limitations of a form of civic engagement that takes up positive emotions as both a tactic and the target of its efforts. I demonstrate that this style of collective action seeks to supply members of the dominant culture with the familiarity required not to see ethnic identity as a threat or a curiosity, such that ethnic minorities can feel comfortable conducting themselves in public spaces on other days of the year. This desire defines a multicultural civil sphere that cannot be secured through rights alone, but only through the erasure of symbolic boundaries preventing the viability of diverse cultural practices and different ways of asserting belonging in public space.Item Essays in Behavioral and Experimental Economics(2015) Lopez Vargas, Kristian Miguel; Ozbay, Erkut; Filiz-Ozbay, Emel; Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)My dissertation consists of three essays on behavioral and experimental economics. In Chapter 1, I introduce an integrated model of risk attitudes and other-regarding preferences that extends the standard notion of inequity discount to lotteries. In this model, a decision maker perceives inequity partly by comparing the marginal risks she and others face. It predicts that fairness considerations will alter risk attitudes, in particular, a higher tolerance to positively correlated (fair) risks compared to negatively correlated (unfair) risks. It is also capable of explaining the behavior by which people help others probabilistically (known as ex ante fairness). Furthermore, in contrast with the existing view of ex ante fairness based on expected outcomes, my model does not imply that stronger ex ante fairness behavior is associated with less risk sensitivity. I study these predictions with evidence from an experiment. I find that subjects take more risks when outcomes are ex post fair compared to when they are ex post unfair. I confirm ex ante fairness behavior is a common choice pattern and document how, according to the model, it responds to its relative price. Finally, I reject the implication of existing models that stronger ex ante fairness behavior correlates with less risk sensitivity. Chapter 2 is a joint work with Professor Brit Grosskopf (University of Exeter, UK). People communicate in economic interactions either aiming to alter material outcomes or because they derive direct satisfaction from expressing. In our study, we focus on the latter, the non-instrumental motivates, and find that this less researched aspect of expression has important economic implications. In particular, we experimentally study ex-post verbal expression in a modified Power-to-Take game and document people's willingness to pay for this kind of expression possibility. Our experiment contributes to previous studies discussing the role of mood-emotional states. We find that purely expressive as well as reciprocal motives are both non-trivial components of the valuation for non-instrumental expression. We demonstrate that expression possibilities have important impacts on welfare beyond what our standard economic view predicts. In Chapter 3, Emel Filiz-Ozbay, Erkut Ozbay and I study multi-object auctions in the presence of post-auction trade opportunities among bidders who have either single- or multi-object demand. We focus on two formats: Vickrey auctions where package bidding is possible and simultaneous second-price auctions. We show that, under complementarities, the Vickrey format has an equilibrium where the objects are allocated efficiently at the auction stage whether resale markets are present or not. The simultaneous second-price, on the other hand, leads to inefficiency with or without resale possibility. Our experimental findings show that the possibility of resale in second-price auctions decreases the efficiency rate at the auction stage compared to the no resale case. However, after resale, the efficiency rate in second-price is as high as that of Vickrey auction without resale outcomes in the experiment. Preventing resale neither benefits nor hurts auction revenues in a second-price format. This last chapter has been recently published in Games and Economic Behavior, Volume 89, Pages 1-16, January 2015.Item The Experience of Fiction(2013) Picciuto, Elizabeth Rose; Carruthers, Peter; Levinson, Jerrold; Philosophy; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation focuses on some of the philosophical puzzles that are associated with the experience of engaging in fictions. Some of these puzzles are longstanding in the philosophical tradition, viz., the paradox of fiction, the paradox of tragedy, and the phenomenon of imaginative resistance. Another has received surprisingly little philosophical attention: the puzzle of why we engage with fictions at all. I argue against what I will call the Simple Story of fictional engagement. Previous discussions have (to greater or lesser degrees) described engaging in fictions as a matter of entertaining the events described at a fictional world. In the Simple Story, the content of the fiction is decisively determinative of our motivations to engage in fiction and responses to fictions. That is not, however, our experience of fiction. I de-emphasize the role of the content of the fiction in our motivations and responses to fictions. Too little attention has been paid to the role of factors extrinsic to the fiction in explaining the nature of our experiences of and responses to fictions. In general, I stress that the role of the content of the fiction as determinative of our responses is far less important than has been assumed. Some aestheticians have long been interested in psychological data and I am, too. Many, however, are wary of in evolutionary psychology. They are rightfully worried that to explain the beauty of Anna Karenina in terms of hunting on the savannah would be to miss something deep. There is, however, a useful role for evolutionary psychology to play in explaining why we might have motivations and emotional responses to fictions. I explore this idea.Item Applications of Dweck's Model of Implicit Theories to Teachers' Self-Efficacy and Emotional Experiences(2012) Williams, Alexis Ymon; Wentzel, Kathryn R.; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The current study explored Dweck's (1999; Dweck & Leggett, 1988) model of implicit theories in the context of teaching in order to establish its usefulness for describing teachers' beliefs about students' ability and social behavior. Further it sought to explain the connections between teachers' implicit beliefs and their efficacy for instruction and classroom management, and their positive and negative emotional experiences. The factor structure of survey data for teachers in mid-Atlantic school districts was examined to test for classes reflecting implicit and entity beliefs, or beliefs that student attributes are malleable or fixed and unchangeable. Given that previous work in other populations has reflected important connections between individuals' implicit theories, their cognitive and emotional functioning, and their interactions with others, the current study explored whether implicit theories have similar implications for teaching. The categorical distinction between entity and incremental theories was not supported in the analyses. Further analyses were conducted using structural equation models for implicit theories, efficacy, and emotional outcomes, including symptoms of burnout. Implicit theories were associated with efficacy such that tendencies toward incremental beliefs correlated with higher efficacy in well-fitting models. Although implicit theories predicted emotional outcomes in some models such that incremental beliefs were associated with positive emotional outcomes, the effect of the implicit theory variable was not significant in models that included the efficacy variable. In these models, only efficacy was a significant predictor of emotions such that higher efficacy was associated with positive outcomes. Finally, the interaction between implicit theory and efficacy was not significant. These findings fail to support the theoretical connections between the two variables in the implicit theory framework, where low efficacy is expected to predict negative emotional outcomes in the presence of entity but not incremental theories. Instead, with respect to emotional outcomes, teaching self-efficacy appeared to be a more salient predictor than student-directed implicit theories of teachers' emotional experiences overall. Keywords: teachers, teaching motivation, implicit theories, teaching self-efficacy, emotions, affect, burnout.Item Congruence of Self-Other Perceptions about Competence, Peer Victimization, and Bullying as Predictors of Self-Reported Emotions(2006-12-13) Nuijens, Karen L.; Teglasi-Golubcow, Hedwig; Counseling and Personnel Services; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This study examined self-, teacher-, and peer-perceptions of competence, peer victimization, and bullying behavior as they relate to self-reported depression, anxiety, anger, and global self-worth. Participants included 99 second- and third-grade students and their teachers from one school located in the Washington, DC metropolitan area. The sample of students was ethnically diverse (66.7% African American, 17.2% Hispanic, 11.1% Asian American, 5.1% White). Preliminary analyses were conducted to examine the relationships among self-perceptions. As expected, self-perceptions of competence (social acceptance, behavioral conduct, academic competence) positively correlated with one another, where self-perceived victimization and bullying negatively correlated with self-perceived social acceptance and behavioral conduct. As expected, the aforementioned self-perceptions were significantly related to self-reported emotions. Here, self-perceived victimization uniquely predicted self-reported depression and anxiety scores, self-perceived academic competence uniquely predicted self-reported anger scores, and self-perceived academic competence and behavioral conduct uniquely predicted global self-worth scores. Two sets of hypotheses were tested regarding the congruence of self-, teacher-, and peer-perceptions. First, as predicted, teacher- and peer-perceptions more strongly related with one another than with self-perceptions. Linked to this finding, self-perceived victimization and bullying were more highly predictive of self-reported competence, where teacher- and peer-perceived victimization and bullying were more highly predictive of teacher- and peer-reported competence. Second, the relative impact of self-perceptions and discrepancies between self- and other-perceptions on self-reported emotions was examined. This is a departure from past research, which has typically examined self-other discrepancies independent of self-perceptions. Results showed that self-perceptions were more strongly related to self-reported emotions than were self-other discrepancies. However, interactions between these variables in a subset of the analyses argue for the inclusion of self- and other-perceptions in this line of research. The pattern of interactions suggests that discrepancies between self- and other-perceptions had little impact on self-reported emotions for children who reported low competence or high victimization. These children tended to report more negative emotions compared to peers whether their self-appraisals agreed or disagreed with others' appraisals. Conversely, children who reported high competence or low victimization often reported more negative emotions compared to peers when their appraisals were unfavorable relative to others' appraisals.
