Description
The purpose of the current study was to use structural equation modeling-based quantitative genetic models to characterize latent genetic and environmental influences on proneness to three discrete negative emotions in middle childhood, according to mother-report, father-report and in-home observation. One primary aim was to test the extent to which covariance among the three emotions could be accounted for by a single, common genetically- and environmentally-influenced negative emotionality factor. A second aim was to examine the extent to which different reporters appeared to be tapping into the same genetically- and environmentally-influenced aspects of each emotion. According to mother- and father-report, moderate to high genetic influences were evident for all emotions, with mother- and father-report of fear and father-report of anger showing the highest heritability. Significant common environmental influences were also found for mother-report of anger and sadness in both univariate and multivariate models. For observed emotion, anger was moderately heritable with no evidence for common environmental variance, but sadness, object fear and social fear all showed modest to moderate common environmental influences and no significant genetic variance. In addition, cholesky decompositions examining genetic and environmental influences across reporter suggested that despite considerable overlap between mother-report and father-report, there was also reporter-specific variance on anger, sadness, and fear. Specifically, there were significant common environmental influences on mother-report of anger- and sadness that were not shared with father-report, and genetic influences on father-report of sadness and fear that were not shared with mother-report. In-home observations were not highly correlated enough with parent-report to support multivariate analysis for any emotion. Finally, according to both mother- and father-report, a single set of genetic and environmental influences was sufficient to account for covariance among all three negative emotions. However, fear was primarily explained by genetic influences not shared with other emotions, and anger also showed considerable emotion-specific genetic variance. In both cases, findings support the value of a more emotion-specific approach to temperament, and highlight the need to consider distinctions as well as commonalities across emotions, reporters and situations.

Description
Levels of heavy episodic drinking peak during emerging adulthood and contribute to the experience of negative consequences. Previous research has identified a number of trait-like personality characteristics that are associated with drinking. Studies of the Acquired Preparedness Model have supported positive expectancies, and to a lesser extent negative expectancies, as mediators of the relation between trait-like characteristics and alcohol outcomes. However, expectancies measured via self-report may reflect differences in learned expectancies in spite of similar alcohol-related responses, or they may reflect true individual differences in subjective responses to alcohol. The current study addressed this gap in the literature by assessing the relative roles of expectancies and subjective response as mediators within the APM in a sample of 236 emerging adults (74.7% male) participating in a placebo-controlled alcohol challenge study. The study tested four mediation models collapsed across beverage condition as well as eight separate mediation models with four models (2 beverage by 2 expectancy/subjective response) for each outcome (alcohol use and alcohol-related problems). Consistent with previous studies, SS was positively associated with alcohol outcomes in models collapsed across beverage condition. SS was also associated with positive subjective response in collapsed models and in the alcohol models. The hypothesized negative relation between SS and sedation was not significant. In contrast to previous studies, neither stimulation nor sedation predicted either weekly drinking or alcohol-related problems. While stimulation and alcohol use appeared to have a positive and significant association, this relation did not hold when controlling for SS, suggesting that SS and stimulation account for shared variability in drinking behavior. Failure to find this association in the placebo group suggests that, while explicit positive expectancies are related to alcohol use after controlling for levels of sensation seeking, implicit expectancies (at least as assessed by a placebo manipulation) are not. That the relation between SS and stimulation held only in the alcohol condition in analyses separate by beverage condition indicates that sensation seeking is a significant predictor of positive subjective response to alcohol (stimulation), potentially above and beyond expectancies.

Description
Life History Theory suggests that, in order to maximize reproductive fitness, individuals make trade-offs between allocating resources to mating and parenting. These trade-offs are influenced by an individual's sex, life history strategy, and environment. Here, I explored the usefulness of a Life History Theory framework for understanding endorsement of child support laws. This study experimentally manipulated sex ratio, and gathered information about participants' endorsement of child support, sexual restrictedness, and mate value. As predicted, women endorsed child support more than men, whereas men favored greater restriction of child support in the form of required paternity testing. However, in general, results do not support an effect of sex ratio, sexual restrictedness, or mate value on endorsement of child support. Results suggest sensitivity to exploitation in a male-biased sex ratio, reflected by an increase in men's endorsement of paternity testing requirements under a male-biased sex ratio prime. Women, on the other hand, report especially unfavorable beliefs toward paternity testing in a male-biased sex ratio. Although results of the current study are mixed, there remains much to be gained from applying an evolutionary perspective to understanding variability in endorsement of child support.

Description
Previous research on experiences of the endowment effect and buyer's remorse has often failed to compare the two seemingly related phenomena. The current study attempts to provide a framework in which the two can be compared and to offer a possible suggestion as to when it may be beneficial to experience either the endowment effect or buyer's remorse, namely situations of resource scarcity versus abundance. The current study employed an online dating paradigm in which resource scarcity was operationalized as the sex ratio of users on the site. Two hundred and one participants were exposed to a favorable sex ratio, an unfavorable sex ratio, or a no information control condition and asked to bid on potential dates. Once matched with a potential date, participants were asked how willing they would be to give up their date and the minimum amount of points they would request to do so. These dependent variables served as indicators of experiences of the endowment effect or buyer's remorse. Results indicated that the sex ratio of the online dating site did not influence experiences of the endowment effect versus buyer's remorse. Potential mediators and moderators were also investigated although no significant effects were found. Possible reasons for the null results are discussed as well as future directions.

Description
Do emotions help explain our behaviors? Can they condemn us, excuse us, orr mitigate our moral responsibility orr blameworthiness? Can they explain our rationality and irrationality, orr warrant such attributions? Can they be justified orr warranted? Are they constitutive aspects of our consciousness, identity, characters, virtues, orr epistemic status? The answer to these questions, at least to a significant extent, depends on what emotions are. This illustrates the importance of what emotions are to academics across multiple disciplines, as well as to members of governing bodies, organizations, communities, and groups. Given the great importance of emotions to various aspects of our lives, this dissertation is about the relevance of the topic of emotion as an area of study for the discipline of philosophy. This dissertation is also broadly about the need to bridge the interests, concerns, and collective bodies of knowledge between various distinct disciplines, thereby contributing to the process of unifying knowledge across the various disciplines within the realm of academia.
The primary aim in this dissertation is to initiate the unification of the interests, concerns, and collective bodies of knowledge across disciplines of academia. To do so, however, this dissertation aims to bridge some disciplinary divides between the disciplines of philosophy and psychology. I fulfill this aim by first demonstrating that interdisciplinary research and theorizing is needed within the disciplines of philosophy and psychology. I do this by considering how the problem of skepticism arises within these two disciplines. I also derive, propose, and argue for the acceptance of a new foundation for academic research and theorizing in response to the problem of skepticism. I refer to my proposal, in general, as The Proposal for Unification without Consilience (UC).

Description
Envy may be an emotion shaped by evolution to resolve large resource disparities in zero-sum ancestral environments. Previous research has found evidence for two types of envy: benign envy, which drives greater effort and self-improvement; and malicious envy, which drives hostility toward the better-off target. We predicted that perceived resource scarcity would stoke either type, moderated by individual differences. Specifically, we predicted that high self-esteem would steer people toward benign envy and self-improvement, whereas narcissism would spark malicious envy. After completing the Rosenberg self-esteem scale and the Narcissism Personality Inventory (NPI-16), participants were randomly assigned to either read an article detailing severe cuts to university financial aid budgets (scarcity) or an article summarizing various forms of financial aid (control). Each article ended with the same envy-inducing paragraph about a particularly affluent scholarship-winner, after which participants completed a measure of both envy types, capturing feelings, appraisals, and behavioral tendencies. Results show that self-esteem predicts less malicious envy, while narcissism and scarcity predict more. Self-esteem and narcissism interact such that self-esteem dampens the effect of narcissism on malicious envy. Self-esteem predicted benign envy when narcissism was low, but not when it was high.

Description
The relationship of attachment style to both the selection and efficacy of emotion management strategies in adult dyadic contexts is not well elucidated. In non-romantic contexts, the interplay between emotion management and individual attachment style may provide a better understanding of how affect can be mitigated in daily life. The present study investigated these interactions by studying 56 pairs of college age women who were close friends. Participants were asked to have a conversation about a current source of concern/distress to one partner, while seated in the laboratory. After the conversation, participants were asked to report their subjective experience of several emotions during the conversation, such as ‘sadness,’ ‘joy,’ and ‘fear.’ Participants were also asked to complete a questionnaire assessing adult attachment style, specifically attachment anxiety and avoidance. Behavior during the conversation was coded for co-rumination and co-cognitive reappraisal by the “listener.” Listener attachment insecurity showed a trending association with increased use of co-detached reappraisal, for both avoidance (p=0.14) and anxiety (p=0.14). Listener attachment insecurity also predicted lower use of co-rumination, for both anxiety (p=0.10) and avoidance (p=0.02). Speaker attachment insecurity moderated the relationship between co-detached reappraisal and speaker emotion. Greater co-detached reappraisal predicted higher reports of non-fear negative and positive emotions, but only for high-avoidance speakers. Greater co-detached reappraisal also predicted greater non-fear negative emotions among speakers high, but not low, on attachment anxiety. Greater listener use of co-positive reappraisal was associated with higher reports of speaker fear; this effect was not moderated by speaker attachment style. These findings are discussed in relation to theoretical conceptions of attachment style, and in terms of the impact of context on emotion.

Description
This paper explores the idea of xenophilia and the circumstances under which it may occur. Xenophilia is the preference for an outgroup member over an ingroup member. This preference does not have to be amicable, and in fact can be exploitative under certain circumstances. Previous research indicates that xenophobia is much more common, but a few researchers have found support for the existence of xenophilia. To experimentally test the circumstances under which xenophilia might occur, I conducted a survey-based experiment on Amazon’s Mechanical Turk. This consisted of directed visualizations that manipulated participant goal (self-protection vs. mate acquisition) and the resources offered by both a fictitious outgroup and the hometown ingroup, followed by measures of ingroup/outgroup preference. I hypothesized that when the resource offered by the group addressed the participants’ goal, they would prefer the group with the “matched” resource—even if it was the outgroup providing that resource. My hypothesis was not supported, as the univariate analysis of variance for preference for the outgroup was not significant, F (2, 423) = .723, p = .486. This may have occurred because the goal manipulations were not strong enough to counteract the strong natural preference for ingroup members.

Description
Infectious disease presents a serious threat to our fitness. The biological immune system provides several mechanisms for dealing with this threat. So too does another system: the behavioral immune system. This second system is proposed to consist of a set of evolved cognitive, affective, and behavioral strategies for reducing the likelihood of infection, including xenophobia, traditionalism, and food neophobia. In the present work, I investigate how another suite of fairly novel culturally-learned disease avoidance strategies, namely hygiene behaviors and knowledge of germ theory, are related to the behavioral immune system. Across two studies, I find that individuals who engage in more hygiene behaviors show less evidence of reliance on several elements of the behavioral immune system (i.e., xenophobia, traditionalism, food neophobia). Similarly, individuals who know more about germ theory show less engagement in behavioral immune system components. These findings suggest that effective cultural strategies for avoiding infectious disease may supplant older, evolved psychological strategies with the same purpose.

Description
As the use of social media becomes more prevalent, especially in adolescents and young adults, there is a growing need to understand how social media use affects psychological well-being in the emerging adult population. Prior research has found that exposure to nature reduces stress and increases attention in comparison to urban environments, but nature has not been studied as a way to reduce the potentially negative effects of social media. The current study aimed to determine if viewing social media or nature for a brief time affected psychological well-being, social comparisons, future self-identification, and awe, and to test whether viewing nature scenes could buffer the effects of viewing social media. Data was collected from 275 participants using a survey on Amazon Mechanical Turk. Results showed that emerging adults exposed to nature scenes had significantly less negative affect compared to those exposed to their social media feeds. Exploratory analyses showed that those who spent more time outside tended to experience decreased negative affect when they viewed both social media and nature photos, but those who spent more time outside experienced increased negative affect when only viewing social media. Those who used social media more often generally experienced lower negative affect. Findings show that relations between humans, social media, and nature, are complex, and further research into these relations and their underlying causes may be beneficial.
