Little is known about the association between empathic and prosocial tendencies (caring) and internalizing psychopathology in young children. Associations between caring and internalizing problems (INT) were examined in young children (N = 63). Children’s caring was measured using a developmentally appropriate story narrative task about mothers in distress; narratives were rated for themes of caring. No general associations between caring and INT were found. A marginally significant, negative quadratic relation between themes of empathy and INT was found in boys (low levels of INT were related to both high and low levels of empathy). Children’s concern reactions were marginally, negatively associated with INT in children of nondepressed mothers. Overall, findings indicate that associations between caring and INT in preschool-aged children are present only under specific conditions, highlighting the importance of gender and maternal psychopathology in elucidating the role of caring in complicated risk cascades that may result in INT .

abstract: Numerous published studies and a meta-analysis suggest that priming religion causes an increase in prosocial behaviors. However, mediating mechanisms of this purported causal relationship have not yet been formally tested. In line with cultural evolutionary theories and their supporting evidence, I test the proposition that public self-awareness mediates the effect of priming religion on prosociality. However, other theories of religion suggest that persons may feel small when perceiving God, and these feelings have predicted prosociality in published research. In line with this, I also test whether a sense of small self and, relatedly, self-transcendent connection, are possible mediators of the religion priming effect on prosociality. In this study, I implicitly prime religion and test whether the above constructs mediate a potential effect on prosocial intentions. Although self-transcendent connection predicted prosocial intentions, the implicit prime affected neither the mediating variables nor prosocial intentions, nor were any significant indirect effects evident. Thus, no causal evidence of mediation was found. In addition, I examined whether God representations moderate the path from implicit religion priming to each proposed mediator. The results suggest that a benevolent God representation moderates the effect of religion priming on self-transcendent connection and that an ineffable God representation moderates the effect of religion priming on sense of small self. Lastly, I tested for mediation with a cross-sectional path model containing religiosity and belief in God as predictors. The results suggest that religiosity, controlling for belief in God, predicts prosociality through self-transcendent connection but belief in God, controlling for religiosity, does not predict prosociality. Implications for the religion priming literature and, more generally, the psychology of religion, are discussed. / Dissertation/Thesis / Masters Thesis Psychology 2018

The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-sectional online survey was conducted during the first wave of the pandemic, involving 6697 respondents across 20 countries. Results showed that 72.9% of participants reported positive intentions to be vaccinated against COVID-19, whereas 16.8% were undecided, and 10.3% reported they would not be vaccinated. At the individual level, prosociality was a significant positive predictor of vaccination intentions, whereas generic beliefs in conspiracy theories and religiosity were negative predictors. Country-level determinants, including cultural dimensions of individualism/collectivism and power distance, were not significant predictors of vaccination intentions. Altogether, this study identifies individual-level predictors that are common across multiple countries, provides further evidence on the importance of combating conspiracy theories, involving religious institutions in vaccination campaigns, and stimulating prosocial motives to encourage vaccine uptake.

Five studies investigated the links between rights-focused (RFM) and duty-focused mindsets (DFM) and prosociality. Making salient both RFM and DFM in a within-participants designs, Studies 1-2 examined the relationships of RFM and DFM with a number of outcomes related to prosocial attitudes. Results indicated that RFM and DFM both uniquely increased prosociality. Experimentally inducing either RFM or DFM in a between-participants design, Study 3 found that RFM had stronger effects on prosocial outcomes than DFM. Further, Study 3 showed that this relative advantage of RFM over DFM in boosting prosociality was due to RFM (relative to DFM) increasing people’s perceived importance and relevance of individualizing morality (harm and fairness). Study 4 thus explored the possibility that RFM’s greater default potential to increase prosociality is due to the inherent focus of rights on individuality, and whether, by the same token, DFM strengthen its potential to increase prosociality as long as the situation is highly individualized. Adding a baseline to the design of Study 3, and using a vignette paradigm, Study 4 showed that in a context of interpersonal helping (i.e., a highly individualized context), relative to baseline both RFM and (especially) DFM increased people’s prosocial attitudes and behavioral intentions. In a 2x2 design, Study 5 experimentally manipulated mindsets (RFM vs. DFM) as well as individuality (high vs. low, asking participants to think about someone in their inner or outer social network). In line with the individuality explanation, there was a general effect of individuality, prosociality being higher (across both RFM and DFM conditions) when participants thought about someone in their inner rather than outer social network. Together, these studies provide evidence for the prosocial potential of RFM; illuminate the roots of this potential; and, by doing so, show a way to leverage this knowledge to increase the prosocial potential of DFM.

People differ, often strikingly, in their views on desired social structures and processes. For example, while some value ethnic diversity in their society, others believe non-indigenous individuals (whatever that might mean) should be repatriated to their land of origin. Similarly, whereas some believe religion should play no role in determining social policy, others strongly advocate the importance of living according to religious scripture, including at a social level. This variation in attitudes, and its implication for societal cohesion, has made research on the origins of social and political attitudes of enduring interest to psychologists, sociologists, political scientists, among many others. The goal of the current thesis was to extend work in this literature in two key ways: Firstly, I examined whether political attitudes can be understood within a personality system model. This work addresses previous mixed results on the links of basic personality traits to political conservatism. In Chapter 3, I test predictions from this model; namely, that direct influences on political behaviour flow from moral values, with personality mostly acting indirectly via these moral values, rather than directly affecting political attitudes. Findings from two studies (published as Lewis & Bates, 2011a) supported these predictions suggesting that the new model helps explain inconsistencies in previous research attempting to link personality to political orientation that have not included the intermediary level of values. Secondly, I examined the genetic architecture of social attitudes constructs in three separate studies. Chapter 4 addressed whether in-group favouritism reflects heritable effects, and, secondly, whether race-favouritism was accounted for broad or specific genetic effects. Results indicated that a common biological mechanism exists facilitating generalised favouritism, with evidence for additional genetic effects specific to each form of group favouritism. These findings(published as Lewis & Bates, 2010) suggest that (at least) at the genetic level, race favouritism is multiply determined. In Chapter 5, I examined whether prosocial obligations across the domains of welfare, work, and civic obligation share a common genetic basis, or reflect specific heritable components (published as Lewis & Bates, 2011b). In females, results indicated the existence of a common heritable factor underlying each of these prosocial obligations. In males, a prosocial factor was also observed; familial effects (genetic and shared-environment effects were indistinguishable) influenced this general mechanism. At the domain-specific level, modest genetic effects were observed in females for civic and work obligations, with shared environment effects influencing welfare obligations. In males, genetic influences were observed for welfare obligation, with unique-environments affecting work and civic duty. Finally, in Chapter 6, I present work examining the genetic architecture of religious belief. Although genetic factors are known to influence strength of religious belief, the psychological mechanism(s) through which this biological influence is manifest are presently unknown. Two non-theological constructs – 1) need for community integration and 2) need for existential certainty – were hypothesised to account for the genetic effects on religiosity. The results supported this hypothesis, with genetic influences on these traits wholly accounting for the heritable basis of religiosity, suggesting that religion “re-uses” systems involved in meeting both social and existential needs.

Researchers and lay people alike have long held an interest in understanding the antecedents, mechanisms, and consequences of prosocial behaviours: Acts people behave in ways that benefit others, such as cooperation, altruism, care-giving, empathy, sympathy, and compassion. Numerous lines of inquiry have now documented that acting prosocially carries many benefits for not only the recipient, but also the actor. For instance, acting prosocially attracts social capital, social support, and boosts interpersonal relationships; prosociality also increases one’s well-being, happiness, and has long-term physical and mental health benefits. While much of the past work has focused on the main effects of prosociality on various positive outcomes, one area that has received limited attention is understanding the contextual factors and individual differences that moderate these relationships. In the present thesis, I focus on understanding how socioeconomic status (SES) acts as a moderator of the link between prosociality and numerous positive outcomes. In particular, I examined how prosociality is related to building social networks through weak ties, coping with daily stress, and building interpersonal skills. Across these relationships, I examined how SES moderates the link between prosociality and each outcome. My research was guided by the SES-prosociality paradox: That while the rich have access to far greater resources – and thus the ability to act prosocially – it is the poor that tend to act most generously. I theorized that one reason for this paradox is that people across different SES strata benefit differently from acting prosocially. In particular, I reasoned that the people from lower SES backgrounds will tend to have stronger relationship between prosociality and various positive outcomes than people from higher SES backgrounds. To test this hypothesis, I conducted numerous empirical studies using multiple methods – analysing data from subjective reports via surveys and existing data from social media, running natural experiments, and conducting lab experiments using genetic and pharmacological challenge methods. In Chapters 2 and 3, I found that people who act prosocially tend to attract more weak social ties – this is only true for the relatively poor. In Chapter 4, I tested how empathic traits relate to better coping strategies for both lower and higher SES individuals, and found a complex pattern of differing benefits. Finally, in Chapter 5, I found that intranasal oxytocin improves emotional theory of mind, but only for the low SES individuals.

Doctor of Philosophy / Department of Psychology / Donald A. Saucier / Three studies were conducted to further validate the belief in pure evil (BPE) and belief in pure good (BPG) scales (Webster & Saucier, 2012). Study 1 assessed the relationships between BPE, BPG, and sociopolitical ideology, while Study 2 assessed the relationships between BPE, BPG, and various forms of religiosity. Study 1 and Study 2 also tested whether BPE and BPG predicted aggression and helping via support for relevant foreign (Study 1) or domestic (Study 2) policy issues above and beyond sociopolitical attitudes and religiosity, respectively. Study 3 tested whether BPE and BPG predicted evaluations of a prototypically (vs. non-prototypically) evil perpetrator and a prototypically (vs. non-prototypically) good apprehender. Together, these three studies showed that BPE consistently related to greater aggression and less helping, while greater BPG consistently related to less aggression and more helping, while demonstrating convergence but not redundancy with variables known to justify/suppress aggression or helping. In sum, these studies further demonstrate the reliability and validity of the BPE and BPG scales as well as provide solid groundwork for future correlational and experimental research on these constructs.

Cooperative behaviour among unrelated individuals is an evolutionary paradox. Research suggests that an individual’s propensity to cooperate and its response to experiencing cooperation or defection from its social environment consistently varies among individuals and as a function of external factors. The biological and psychological underpinnings of such behavioural variation remain unknown; they can, however, provide more insight into the evolution and maintenance of cooperation among non-kin. This thesis explores the proximate effects of experiences of cooperation or defection from the social environment, as well as possible proximate drivers of cooperative behaviour, using the Trinidadian guppy (Poecilia reticulata) as a study system. Firstly, the behavioural rules underpinning an individual’s decision to cooperate or not with unfamiliar individuals in the presence of specific or non-specific information were explored. When fish had information about their social partner’s cooperativeness, they behaved in a manner consistent with direct reciprocity, copying their partner’s last move. When paired with an ostensibly novel partner, a different, or at least additional, behavioural rule seemed to be employed. In order to help understand the drivers of individual variation in cooperative behaviour, phenotypic selection on cooperativeness was carried out over three filial generations, resulting in fish of high cooperativeness (HC) and low cooperativeness (LC). The divergence of individual cooperativeness observed between the two phenotypic selection lines suggests that cooperative behaviour in the context of predator inspection is at least in part heritable. Cooperative behaviour of F3 fish was found not to correlate with boldness or exploratory behaviour; HC and LC fish did, however, differ in some aspects of sociability and agonistic behaviour. Possible proximate neuromodulatory mechanisms underlying these differences in cooperativeness were also explored, focusing on brain expression patterns for the isotocin receptor (itr) gene in F3 females. HC females were found to have higher mid-section itr expression levels than LC females. Finally, I explored the effects of experiencing cooperation or defection on monoaminergic neurotransmission, which is thought to instantiate the effects of such experiences on the individual’s internal state. My findings suggest that experiencing cooperation or defection from the social environment affects internal state; this phenomenon may be crucial for the appropriate adjustment of the behavioural response to such experiences, and for the emergence of behavioural rules such as generalised reciprocity. Taken together these results suggest that neuromodulatory mechanisms are pivotal for the perception of stimuli from the social environment in the tested cooperative context and that variation in cooperative behaviour may be underpinned by individual differences in the structural properties of such systems. They also provide insight into how behavioural input may affect the behavioural response to such experiences, and ultimately how such mechanisms may lead to the evolution and maintenance of cooperation.

<p>Viewing peer relations as markers of children’s adjustment, the present thesis examined the associations between disruptive behavior problems (i.e., symptoms of Attention Deficit Hyperactivity Disorder [ADHD] and aggression) and peer relations. A second aim was to examine how children’s cognitive functioning and view of self and of their social standing are associated with their peer relations and interactions. Gender differences in the above relations were also examined. The findings indicate that although disruptive behaviors are related to poor peer relations, low levels of prosociality (Study I) and poor cognitive functioning (i.e., poor executive functioning; Study II) exacerbate children’s peer problems. Further, overly positive perceptions of one’s social acceptance and low global self-evaluations were both related to aggression within the peer group (Study III). As regards gender differences, high levels of symptoms of ADHD and poor executive functioning, had graver consequences for the peer acceptance of girls’ than of boys’ (Study I and Study II) indicating that these characteristics may not fit the cultural stereotype for girls. Results are discussed in terms of viewing poor peer relations as indicators of problematic adjustment, and also, in terms of assessing the particular significance that peer relations have for children’s self-view and behavior within the peer group. Implications of the findings as regards the interactions between behavior, cognitions, and gender on children’s peer relations are also discussed. </p>
