Emerging adults (i.e., individuals from 18 to 29 years old) are at a unique stage in their development and are repeatedly presented with decisions that have important consequences that unfold over time (i.e., intertemporal decisions). Chapter 1 of this dissertation provides a brief overview of emerging adulthood as a developmental stage and presents a rationale for the importance of understanding the relationship between temporal self-perceptions and longitudinal outcomes in emerging adults. Then, in four articles (Chapters 2-5), this dissertation provides evidence for the connection between temporal self-perceptions and positive downstream consequences in college students (i.e., a subsample of emerging adults). Specifically, Chapter 2, examines longitudinal changes in perception of the future self through the first two years of college, how those changes predict downstream academic success, and identifies sex differences in those relationships. Chapters 3 and 4 then extend the research on longitudinal outcomes of future self-perception to downstream outcomes during a global crisis (i.e., the COVID-19 pandemic). Chapter 3 explores the role of perception of the future self as a potential protective and promotive factor for longitudinal mental health during the pandemic. Chapter 4 presents a study during the initial stages of the COVID-19 pandemic that investigates a vivid view of the future self at the start of college as a resource to support downstream resilience for graduating college students—especially for students who are already at an economic disadvantage (i.e., low socioeconomic status). Chapter 5 then broadens the understanding of these relationships by testing the relationship between continuity between temporal selves (i.e., past-to-future) and psychological well-being. Finally, Chapter 6 incorporates the reported findings into a theoretical model, reviews the literature on the constructs to extend the model beyond college students to emerging adults as a developmental group, and discusses avenues for future research.

Perception of the future self (i.e., future self-identification) is an important indicator of outcomes over time and during different life-stages (e.g., adolescence, emerging adulthood, retirement). Although recent research established that future self-identification is comprised of three distinct but interrelated factors (i.e., relatedness, positivity, and vividness of the future self), the current research was the first to consider the stability of that factor structure (i.e., factorial invariance) over extended time and over the course of a major life-stage transition. Using a longitudinal design, this research investigated (1) longitudinal factorial invariance as young adults transitioned into, and became established in, their college education and (2) explored differences in factor stability across demographic groups (i.e., sex; college generation status). Results indicated that as students progressed through their first three semesters of college, future self-identification had a stable factor structure over the short-term. However, from the first week of college to when students were established in college, strong factorial invariance (i.e., invariance of the item intercepts) did not hold. In general, there were not differences in future self-identification factor structure by sex. However, from the first year of college to the second year, strict invariance was not supported (i.e., the item residual variances were not invariant between men and women). This sex difference appeared during the first stage of the transition into college and diminished as students became established in their college career. Finally, complete factorial invariance was established between first-generation and continuing-generation college students suggesting that the future self-identification factor structure did not differ based on college generation status. Findings provide crucial information regarding the validity of mean comparisons of future self-identification across a transition into a life-stage and across demographic groups. Future research may build on this foundation to better understand the sources of factorial non-invariance.

The broaden-and-build theory of positive emotion suggests that positive emotions should broaden thought and behavior repertoires in order to develop lasting resources. In the social domain, this means deploying a variety of affiliative strategies in order to build cooperative relationships. A functionalist perspective on positive emotion suggests that different positive emotions should have distinct effects on these affiliative mechanisms. This study elicited awe, amusement, pride or a neutral control in pairs of same sex strangers. They then completed an open-ended "getting to know you" conversation, which were recorded and coded for affiliative behaviors—smiling, laughter, mimicry, and asking questions. After, they rated their perception of the other as complex and how much they liked each other. Then they played the prisoner's dilemma game. Results indicate that there was a significant mediated effect such that being in the pride condition predicted greater smiling, and smiling predicted cooperation on the prisoner's dilemma. This was true both when an individual's own smiling was predicting their cooperative behavior and when their partner's smiling was predicting their cooperative behavior. However, these effects were only seen in female dyads, not male dyads. There was also a significant mediated effect such that pride led women to ask more questions, which led partners to like each other more. Additionally, awe led to greater mimicry in men, which in turn led to greater cooperation. In women, awe led to greater perception of the other as complex. Overall, these results indicate that there are broaden and build effects of positive emotions, but these are specific to both the emotion and the sex of the interaction members. This is also the first study to demonstrate both an actor and a partner effect of smiling on cooperation in a prisoner’s dilemma. An important area for further inquiry will be the interaction of emotion and sex in predicting social behavior. While sex differences in responding to threats have been characterized by the “tend and befriend” versus “fight or flight” action patterns, a similar approach may also need to be developed for sex differences in response to opportunities.

Negative behaviors targeting gay men and lesbians range from violent physical assault to avoiding social or physical contact, with very different implications for those targeted. However, existing theoretical accounts of sexual prejudices are unable to differentially predict these various behaviors, leaving a large theoretical hole in the literature and hindering the design of effective interventions. I propose (a) that homosexuality and pro-gay ideology are conceptualized by many lay persons as contaminants analogous to infectious diseases and (b) that anti-gay behaviors can thus be viewed as strategic attempts to prevent, contain, treat, or eradicate the "pathogens" of homosexuality and pro-gay ideology. In three preliminary studies I demonstrate that sexually prejudiced individuals do view homosexuality and pro-gay ideology as contagious, and that sexually prejudiced people report being more likely to engage in aggressive (versus avoidant) anti-gay behavior in conditions that predict an aggressive pathogen-combating response – highly interconnected social networks. The current study explores the effect of a social network manipulation on actual behavioral responses to a gay (versus straight) interaction partner. In this study I show that sexually prejudiced participants engage in more aggression towards a gay partner compared to a straight partner under a highly interconnected network manipulation.

First-generation college students, for whom neither parent has a bachelor's degree, are at an increased risk for dropping out of college compared with their continuing-generation counterparts. This research aims to examine whether varying perceptions of the future may contribute to these differences; specifically, whether presentations of future opportunities with and without a college degree impact academic motivation and performance, and whether this relationship holds for people from different college generation status backgrounds. Additionally, the study explores whether the effect is consistent with regulatory focus profiles--whether someone is motivated to avoid negative outcomes (e.g., prevention orientation) or attain positive outcomes (e.g., promotion orientation). Prevention oriented first-generation students were expected to have increased motivation and performance when asked to contrast the future with and without a college degree, whereas promotion oriented continuing-generation students were expected to have increased motivation and performance by merely thinking about the future with a college degree. Participants consisted of 330 undergraduates from an introductory psychology course. Participants were randomly assigned to presentations of future opportunities with a degree, with and without a degree, or a no-prime control condition. Motivation and performance were assessed using academic motivation and delay of gratification scales and a short anagram task. The proposed hypotheses were not supported; however, important findings emerged from exploratory analysis. First- and continuing-generation college students perceived future opportunities with a college degree similarly, meaning that both first- and continuing-generation students believed that a degree would endow opportunities. Additionally, belief in future opportunities significantly predicted academic motivation, delay of gratification, and anagram performance; thus, belief in future opportunities is a determinant of academic motivation and performance. Finally, first-generation students' performance varied by belief that a college degree would create future opportunities. Therefore, future interventions to increase performance and retention among first-generation students should emphasize the value of a college degree for future success. This research has implications for the understanding of college generation status, academic motivation, and performance.

Twenty-five percent of Americans are first- or second-generation immigrants (US Census, 2012). Thus, it is likely that many Americans identify with at least two cultures, that of the mainstream United States culture, and their ethnic culture from which they came, making them bicultural. However, current understanding of the impact of biculturalism on psychological functioning is quite limited in scope, as few studies have examined this association longitudinally or considered the moderating role of the cultural environment. The present study proposed to take a more comprehensive approach in understanding the consequences of biculturalism on psychological outcomes (i.e., depression, anxiety, and substance abuse symptoms) among Mexican American adolescents, as they belong to one of largest and fastest growing ethnic groups in the United States (US Census, 2013). The present study had two major goals. The first was to examine the influence of biculturalism on depression, anxiety, and substance abuse symptoms longitudinally over the course of two years. It was hypothesized that overall, biculturalism will lead to less depression, anxiety, and substance abuse symptoms. The results partially supported these predictions. For males, biculturalism was related to significantly fewer anxiety symptoms, but not for females. Further, no main effects of biculturalism were found for depression and substance abuse for males or females. The second goal of the study was to examine the potential moderating role of the cultural environment on the influence of biculturalism on mental health symptoms. It was hypothesized that bicultural individuals will exhibit less mental health symptoms in bicultural environments (person-environment fit) compared to more monocultural individuals (person-environment misfit). However, no differences are expected to ii emerge between bicultural and monocultural individuals in monocultural environments, as both groups should be well adapted in these settings. The results did not fully support these predictions. Though, biculturalism for male adolescents was related to significantly fewer anxiety symptoms in home environments where parents reported moderate degrees of biculturalism, and females' biculturalism was related to significantly fewer depression symptoms in neighborhood environments that were relatively bicultural; no effects of biculturalism were found in environments that were the most bicultural. The implications of the findings are discussed.

Recommendations made by expert groups are pervasive throughout various life domains. Yet not all recommendations--or expert groups--are equally persuasive. This research aims to identify factors that influence the persuasiveness of recommendations. More specifically, this study examined the effects of decisional cohesion (the amount of agreement among the experts in support of the recommendation), framing (whether the message is framed as a loss or gain), and the domain of the recommendation (health vs. financial) on the persuasiveness of the recommendation. The participants consisted of 1,981 undergraduates from Arizona State University. The participants read a vignette including information about the expert group making a recommendation--which varied the amount of expert agreement for the recommendation--and the recommendation, which was framed as either a gain or loss. Participants then responded to questions about the persuasiveness of the recommendation. In this study, there was a linear main effect of decisional cohesion such that the greater the decisional cohesion of the expert group the more persuasive their recommendation. In addition, there was a main effect of domain such that the health recommendation was more persuasive than the financial recommendation. Contrary to predictions, there was no observed interaction between the amount of decisional cohesion and the framing of the recommendation nor was there a main effect of framing. Further analyses show support for a mediation effect indicating that high levels of decisional cohesion increased the perceived entitativity of the expert group--the degree to which the group was perceived as a unified, cohesive group¬--which increased the recommendation's persuasiveness. An implication of this research is that policy makers could increase the persuasiveness of their recommendations by promoting recommendations that are unanimously supported by their experts or at least show higher levels of decisional cohesion.

A theme in the life experiences of ethnic minority adolescents is the perception of discrimination and its concomitant challenges. Although existing literature has examined the perception of discrimination in adolescents, little research has examined how the cultural and familial setting may heighten or alleviate the impact of perceived discrimination on psychological outcomes in Latino youth. The current study investigated how traditional cultural values and parent-adolescent relationships prospectively interact with perceptions of group based discrimination to influence Latino adolescent mental health, adjustment, and risky behaviors. Data used from the Parents and Youth Study included 194 Mexican American (MA) adolescents. Adolescents reported on their perceptions of group discrimination, endorsement of traditional Mexican cultural values, and parent-child relationships in the 7th grade (Time 1). The study also used indices of externalizing (mother report), internalizing, substance use and risky sexual behavior (adolescent report) in 10th grade (Time 2). The findings demonstrated that traditional Mexican cultural values, particularly familism, moderated the relationship between perceived group discrimination and adolescent sexual behavior. Additionally, a better overall relationship with mother and father buffered the detrimental effects of perceived group discrimination on risky sexual behavior. The current work discusses future directions of how the context of culture and family may shape an adolescent's response to perceived discrimination and the well-being of minorities.

The current study explored whether intrinsically religious individuals are able to separate the "sin" from the "sinner" (i.e., separate category membership from behavior) when judging homosexual individuals, or whether they are instead subject to the negativity bias (judgments based solely on category membership) in moral judgments. All effects were expected to occur only for participants high in homophobia. Participants were 305 undergraduate male and female students at a large, public university in the southwestern U.S. Respondents read one of five scenarios that described gay or straight targets who were celibate or engaged in same or opposite sex relationships, then were asked to respond to a series of questions evaluating attitudes and behavioral intentions toward the target. Results revealed that homophobia led to a negativity bias in judgments of gay targets, which was intensified by intrinsic religiosity. However, individuals high on intrinsic religiosity and high on homophobia also differentiated between gay targets based on sexual behavior, such that gay targets who were celibate or in an opposite-sex relationship were rated more favorably than gay targets in a same-sex relationship. These findings demonstrate that the negativity bias and "sin vs. sinner" differentiation may both be occurring for intrinsically religious individuals. The moderating effect of homophobia on the interaction between intrinsic religiosity and judgments of gay and straight targets shows us that religiosity itself is not inherently tolerant or intolerant.
