Understanding the rational and ethical sense that people make of their actions and experiences requires understanding the lives they are trying to live. The narrative visions of a good life that are dominant in a society thus represent an important aspect of cultural orientation. To gain insight into the form and function of these visions, two studies were conducted. In Study 1, the various criteria by which people judge their lives as good or worthy were examined using multidimensional scaling of responses from four different cultural groups of students: Chinese, East Asian Canadian, South Asian Canadian, and Western European Canadian. The results revealed two underlying structural dimensions on which both criteria and cultural groups could be differentiated. One reflected the locus of criterial goods and the other their morality. The clearest cultural contrast was between Chinese participants, who tended toward the prudential, materialistic, and hedonistic pole of the morality dimension, and South Asians, who tended more toward the spirituality and beneficence pole. In Study 2, the content of personal narratives produced by Chinese and South Asian students was analyzed to examine whether their contrasting orientations to the good life would be reflected in the kinds of life experiences they recounted. Some evidence of correspondence in this regard was found.

Children with fetal alcohol spectrum disorders (FASD) have deficits across many cognitive, behaviour and social domains. However, despite social difficulty being proposed as a main deficit following prenatal alcohol exposure, the nature of their deficient social behaviour is largely unknown. One process that may underlie difficulties in social functioning is poor social cognition, which refers to one’s understanding of the self, others and social world. The primary goal of this dissertation was to determine whether social cognitive deficits represent a core disability underlying the socio-behavioural problems of FASD using a bottom-up approach. The first level of this approach is represented by face processing. Global and independent face feature processing was compared between FASD and normal controls (NC) using experimental and clinical measures. Eye gaze processing was investigated next using experimental and clinical tasks. At the highest level of the bottom-up approach, social perspective taking, including theory of mind and empathy were examined, along with how these abilities related to parent-rated behaviour. Finally, the lowest level consisted of specific aspects of the social neural network. White matter in three limbic pathways was investigated using diffusion tensor imaging (DTI). Results generally supported the bottom-up approach of social cognition in FASD. These children showed impaired processing of face features, when matching mouth shapes and partially occluded identity, compared with NC. The FASD group was slower to process gaze and arrow cues, suggesting impaired attention shifting. Children with FASD also showed impairments in social perspective taking, including understanding false beliefs and empathy, and these impairments were related to parent-rated attention and social problems, and autistic-like traits. Deficits in theory of mind got worse with age in FASD and empathy showed distinct sex-related differences. Although no group differences were observed on DTI indices, groups did show different age-related changes in white matter. In conclusion, deficits at each level of the current bottom-up approach may underlie the social impairments in FASD and may contribute to their broader social behavioural phenotype. The results from this dissertation have potential to inform clinical practice and lead to more effective diagnostic and treatment approaches in FASD.

Research has shown that social pressure is related to treatment motivation and plays an important role in treatment engagement in adults with problematic substance use. Despite the shifts in autonomy and decision-making in emerging adulthood, the factors affecting treatment motivation (e.g., readiness to comply with treatment) and motivation to change (e.g., problem recognition and taking steps towards change) during this period have been largely ignored. In this study, 134 youth presenting to an outpatient substance abuse program completed questionnaires investigating substance use history, mental health, social pressure to reduce use and enter treatment, and motivation. Results indicated that peer pressure accounted for significant variance in internal positive and internal negative treatment motivation. Family pressure was related only to external treatment motivation. Neither social network source had a significant impact on motivation to change. Limitations, directions for future research and treatment implications are discussed.

Pitting long-term goals against short-term desires is among the most difficult tasks in human decision-making. According to behavioural and neuroeconomic theories of self-regulation, these decisions involve a competition between “hot” reward-focused impulses and “cool” cognitive control mechanisms. The current dissertation examines this topic from the perspective of social and personality neuroscience, exploring the cognitive and affective dynamics underlying the self-regulatory process. Chapters 1 and 2 explore how the “hot” system is dispositionally expressed in the personality trait of Extraversion, and the implications of this finding for decision-making behaviour. Turning to the “cool” system, Chapter 3 examines the role of effective performance monitoring in predicting real-world self-regulatory outcomes. Finally, Chapter 4 addresses the question of whether self-regulatory performance can be improved, reporting the effects of a goal-setting intervention on long-term decision-making. Results across the studies are discussed within an integrative model of self-regulation, situated within a social-personality neuroscience framework.

Previous research suggests that the amount of food that women eat may fluctuate depending on their impression-management motivation; however, the results do not provide direct evidence supporting such an explanation. That is, no studies conducted to date have actually manipulated impression-management motivation and measured its effects on eating behavior. The present program of research aimed to confirm that eating behavior in women does, in fact, change as a result of impression-management motivation. Experiments 1, 2, and 3 tested this by manipulating impression-management motivation via direct and explicit instructions. Experiment 3 was also designed to investigate how impression-management motivation might affect eating in situations in which females are eating with a friend (as opposed to a stranger). The results demonstrate that women motivated to make a good impression on a male stranger (Experiments 1 & 2) and a female stranger (Experiments 2 & 3) eat less than do those for whom the desire to make a positive impression has been disrupted. The results also confirm previous findings showing that women eat less when eating with a male stranger than when eating with a female stranger (Experiments 1 & 2). The findings from Experiment 3 suggest that there may be a different pattern of eating associated with impression-management motivation when women eat with female friends; it was found that participants ate more with a friend when they were motivated to make a good impression compared to when this motive was not present. These results may be explained by impression-management theory, in combination with notions about the complexity of female friendships and female-female competition surrounding eating, dieting, weight, and appearance.

How one understands their bicultural identity has implications for how one psychologically reacts to discrimination. The three major goals of this thesis were to explore 1) how young adult, bicultural, ethnic minorities understand their cultural identities; 2) how the individual’s understanding of his or her bicultural identity was associated with reactions to real or imagined experiences of discrimination; and 3) the value of the blended/alternating bicultural distinction in understanding bicultural identity and how that might relate to the association between discrimination and well-being. Young adult undergraduates attending a diverse university campus, mainly of East and South Asian background, were interviewed, asked to complete written questionnaires, or asked to participate in an experimental study concerning cultural identity. Results from the three studies of the thesis suggest common themes in participant descriptions of bicultural identity. Results also demonstrate the direct negative effect of discrimination on mood, and suggest that the distinction between understanding one’s bicultural identity as a stable, cohesive blend of two cultures (Blended Biculturalism) vs. as one that switches between two cultural selves (Alternating Biculturalism), may have implications for differential effects of discrimination on psychological well-being. Alternating biculturals in the discrimination condition reported experiencing more negative mood than alternating biculturals in the non-discrimination condition. Blended biculturals did not show this difference. Alternating biculturals in the discrimination condition also reported experiencing more approach thoughts toward their group than alternating biculturals in the non discrimination condition; blended biculturals did not show this difference either, but rather had high levels of approach thoughts in both conditions. Possible explanations for these results are discussed.

Despite the ubiquity of music and its importance to one’s identity, there has been limited research on individual differences in music preferences. The aim of this dissertation was to examine how music preferences vary across individual differences in stable traits (e.g., gender, personality) and states (e.g., mood) over three studies. The focus of Study 1 was on the influence of the listener’s mood on emotion-based music preferences. The typical preference for happy- over sad-sounding music was found to be mood-dependent, evident after happy and neutral but not sad mood inductions. When the music was emotionally ambiguous (i.e., with cues to both happiness and sadness), happy listeners liked the music more than other listeners, whereas sad listeners perceived it to be more sad-sounding. Study 2 examined how emotion-based music preferences develop. Adults and children 5, 8, and 11 years of age listened to short pieces expressing emotions that varied in arousal and valence: happiness (high, positive), scariness (high, negative), peacefulness (low, positive), or sadness (low, negative). Adults preferred pieces with a positive valence (happy and peaceful), whereas children preferred excerpts depicting high-arousal emotions (happy and scary). Identification accuracy was predictive of a positive-valence bias among 5- and 8-year-olds. A number of other findings related to accuracy and gender differences were also evident. Study 3 examined whether personality differences affect the influence of exposure on liking. Undergraduates completed the Big Five Inventory and provided liking ratings for novel music excerpts as well as for excerpts they heard 2, 8, or 32 times. Higher scores on Openness-to-Experience were related to greater liking for novel excerpts and more rapid satiation. In sum, these three studies highlight that music preferences vary as a function of individual differences and the listening context.

This dissertation uses a multi-method approach to examine the role of online communities as a source of peer-to-peer supportive care for breast cancer survivors. A collection of four studies is presented. Study 1) A systematic search of the Internet identified 111 active online communities for breast cancer survivors with extensive archives of personal health experiences (one third had over 100,000 posts each as of 2010-10-26). More than one-third (36.0%) were initiated by breast cancer survivors or loved ones, and more than two-thirds (69.5%) were maintained with little or no professional input. Study 2) An analysis of Facebook (www.Facebook.com) identified 620 public breast cancer groups containing a total of 1,090,397 members as of 2008-11-23. The majority of groups were created for fundraising and awareness purposes (92.6%), rather than supportive care (7.4%). Study 3) One hundred breast cancer survivors, known to provide peer support were surveyed on their supportive care needs and use of online communities. Two-thirds (68.6%) of the 73 respondents reported at least one unmet need, most frequently (30 to 40%) concerning sexual problems, stress, survivor identity, fear of recurrence, and ongoing symptoms or side effects. About one-third (31.5%) used online communities predominantly during and while recovering from treatment. Reasons for non-use included lack of need, self-efficacy, trust and awareness. Study 4) Twelve breast cancer survivors who participated in the previous study were interviewed on how and why they used online communities. Unmet needs drove use, particularly during periods of stress, uncertainty or insufficient local support. Online communities served as a unique supportive care resource due to their quality of information, reassurance from similar others, availability, anonymity, and limited commitment. Social support, technology adoption and health behaviour theories help to explain use. Online communities have the potential to fill gaps in health care services by addressing the supportive care needs of breast cancer survivors in a way that may not be available elsewhere, and survivors may play an increasingly important role as care providers. Future research must focus on overcoming barriers to use, and identifying factors that enhance their effectiveness among diverse groups.

The use of coercion to induce entry to addiction treatment is controversial and a large body of research has accumulated considering ethical issues, benefits, and repercussions. However, development of evidence-based policy and practices is hampered by limitations of existing literature. Theoretical and empirical work on self-determination suggests that perceptions of coercion have negative implications for motivation, behaviour change, and psychological well-being; however, these insights have not generally informed research on coerced treatment. The present work seeks to further understandings of the meaning and effectiveness of coerced addiction treatment through a theory-based, prospective study of coercion and treatment processes. The sample includes 276 adults admitted to an outpatient counseling program for alcohol- and drug-related problems. At admission, participants completed questionnaires on motivation, perceived coercion, and pressures to enter treatment. Two months later, a second questionnaire assessed engagement in treatment and substance problem severity (follow-up rate = 74.3%). Retention was determined via self-report and agency records. Analysis was guided by a conceptual model based on Self-Determination Theory. Perceived coercion at admission was associated with greater pressures from legal and informal sources, and lower substance problem severity. Fewer than half (45.7%) of participants were still attending treatment at 2-month follow-up. Clients who reported greater coercion were more likely to leave treatment within the first 2 months, and to qualify that decision by statements indicating a lack of perceived need for continued treatment. Greater autonomous motivation was associated with higher client confidence in treatment, and lower perceived coercion and greater informal pressure were associated with greater resolution of substance problems in the weeks following admission. This work contributes empirical evidence to ongoing debates over the legitimacy of coerced addiction treatment by reframing relevant concepts in terms of client perspectives and evaluating the impact on treatment processes. Results raise questions about previous conclusions of the effectiveness of coerced treatment and suggest many future avenues for research. In particular, research is needed to evaluate the longer-term implications of coercion and the changing nature of perceptions and motivation during treatment.
