Master of Science / Department of Psychology / Richard J. Harris / Previous research has indicated that many factors influence the likelihood of using the central or peripheral routes of processing during exposure to a persuasive message, including involvement in the message. Previous research has generally focused on response involvement, which is based on outcome, while the focus of the present study is involvement based on personal investment. In the present study, 229 undergraduates were assessed on their trait empathy toward animals, and attitudes toward animals. They read a strong or weak persuasive message presented by either an attractive or less attractive writer. This design replicated previous findings by Bae (2008) on empathy and attitude change, and extended them by examining them experimentally, with a focus on issue-based involvement, which relies on moral or ego involvement. Participants were tested on several distinct DVs designed to indicate their change in attitude and behavior. Results varied for each DV, with source attractiveness predicting willingness to wear a button and display a bumper sticker, but with trait empathy predicting willingness to adopt a pet and vote to support a petition. The results imply that participants relied on different routes of processing depending on the DV, and that the role of emotion in issue involvement may inform advertisers in ways to effectively increase the likelihood of paying attention to a message.

The UK is required to reduce its greenhouse gas emissions by 80 per cent from 1990 levels, by 2050. Greenhouse gas emissions attributed to the UK higher education sector have increased by 34.5 per cent from 1990 to 2005. Higher education institutions have a unique role in the UK greenhouse gas emissions inventory, beyond management of their own estates and compliance with policy and legislation, higher education institutions have responsibilities as innovators and educators, inspiring students and employees through example and best practice. This study sought to understand acceptability of greenhouse gas emissions reduction policies among employees of a higher education institution. The value-belief-norm theory was used in a questionnaire to understand individual attitudinal factors thought to influence policy acceptability (N=405). Recognising that an employee's attitudinal factors may be influenced by their work colleagues, this study used social network analysis to understand the social context within which individual attitudinal factors sit. Support was found for higher education institutions to reduce their greenhouse gas emissions. Employees found policies that encouraged desired behaviours, such as assistance with train travel costs and working from home, to be more acceptable than policies that discouraged undesired behaviours, such as doubling the price of a car-parking permit. Support was found for the structure and content of the value-belief-norm theory, but logistic regression suggested that it provided a weak explanation of employee policy acceptability, indicating that other factors may have a greater role. Analysis of workplace social networks suggested that employees have small social groups (x̄=8) and do not select to be close to colleagues that reflect their own perspectives. Practitioners and policymakers should seek to address this void in environmental social norms through recruitment of more environmental champions to deliver strong and persuasive pro-environmental messages.

Maternal depression is a common mental health disorder that can have significant adverse effects on child functioning, including increased rates of child behaviour problems. Adopting a resilience approach highlights that despite the increased risk there is considerable variation in child behaviour development, although mechanisms through which this occurs are not well understood. This thesis investigates positive parenting, harsh parenting, and child inhibitory control as developmentally salient processes that may explain why some children of mothers with depression develop more positive behaviours than others. Analyses were conducted using data from the Early Steps Multisite Study, a longitudinal randomised controlled trial that includes 731 ethnically diverse families from three sites across the United States. Baseline measures were completed at child age 2, with annual follow-up assessments until age 8. These analyses used mother self-reported depressive symptoms, observed measures of parenting, alternate caregiver-reported child inhibitory control, and mother- and teacher-reported child externalising behaviours. Categorical and continuous variables of maternal depression and child behaviour were tested to explore the implications of different analytic approaches, particularly with reference to the concept of resilience. Logistic regression results indicate that child inhibitory control is a robust predictor of developmentally normative behaviours for children of mothers with depression and children in general. Linear regression results support a risk-specific effect of harsh parenting, such that it interacts with maternal depression to predict increased externalising behaviours specifically for children of mothers with depression. Positive parenting appears to predict the behaviour of children in general but not the behaviour of children of mothers with depression. Path analyses indicate that between the ages of 2 and 4, harsh parenting partially mediates the association between maternal depression and child externalising behaviours. Moderated mediation results suggest that children with lower levels of inhibitory control elicit increased harsh parenting behaviours from mothers both with and without depression. Cross-lagged path analyses provide support for reciprocal influence between maternal depression, harsh parenting, and child externalising behaviour, and suggest an impact of maternal depression severity on the establishment of negative patterns of mother-child interactions from age 2. The findings of this thesis support the importance of reducing harsh parenting behaviours particularly for mothers with depression and of improving child self-regulation from an early age. The concept of resilience as a dimensional and potentially reciprocal process is discussed in the context of maternal depression and child behaviour development. Results emphasise that both mother and child are actively involved in influencing processes of resilience. From early childhood, there is a need to support more adaptive patterns of behaviour between mothers with depression and their children in order to increase the likelihood of positive child outcomes over time.

This thesis expands our understanding of the role of several different mating behaviours in the process of forming and maintaining human mating pair-bonds. Chapter 2 investigated within-sex mating strategies and found that their distribution reflects the presence of two phenotypes, one favouring the pursuit of short-term mating and one the establishment of mating pair-bonds, each driven by prenatal testosterone exposure. Chapter 3 investigated the possible functional role of kissing in mating relationships, and found that it was utilised divergently by individuals pursuing different mating strategies, with those interested in short-term mating utilising it to assess the suitability of potential mates at initial relationship stages, and those interested in long-term mating using it to mediate pair-bond attachments. Chapter 4 examined female attitudes towards kissing across the menstrual cycle and found that attitudes varied with cycle phase, mediated by fluctuations in the hormone progesterone. This chapter also investigated the effects of kissing-related information on mate assessment and found that such information influenced mate desirability, even in the presence of typically dominant visual cues. Lastly, Chapter 5 investigated the cognitive effects of established pair-bonds, finding that individuals ‘in love’ with a mating partner show improved empathising abilities, particularly males when it comes to assessing negative emotional states in others. Using an evolutionary framework, each chapter of this thesis contributes novel insights to our understanding of these diverse behaviours. These results suggest that that future research must take into account within-sex phenotypic differences in order to truly understand human mating strategy decisions, and that different mating strategy phenotypes might adaptively utilise the same courtship behaviours in divergent ways. Furthermore, these results also suggest that pair-bonding in humans may be a relatively recent phenomenon, and that the formation of such pair-bonds can have adaptive cognitive effects for males within such bonded relationships.

People turn to others for help and advice during hard times. Early psychologists suggested a ‘talking cure’ as a remedy for emotional turmoil (e.g., Freud, 1916–7/1963; Rogers, 1942). Likewise, folk psychology often sees heart-to-heart conversations as a win-win proposition that brings relief to the afflicted person and reinforces social bonds at the time of need. However, talking about problems does not always help (e.g., Rimé, 2009; Rimé, Mesquita, Boca, & Philppot, 1991; Rimé, Philippot, Boca, & Mesquita, 1992; Rose, 2002). In some cases, problem-talk can be a lose-lose proposition that drags both discussants into depression (Rose, 2002; Rose, Carlson, & Waller, 2007). This thesis examines co-rumination (Rose, 2002), a case of emotional sharing that hurts people instead of helping them, on three levels of analysis (individuals, dyads, and groups). At the individual level, I sketch the life course of co-rumination and replicate earlier findings of gender differences. Furthermore, online survey data (N = 464) links co-rumination with agreeableness and neuroticism. I also demonstrate that co-rumination can be assessed with a brief measure that is 66% shorter than the original. At the dyadic level, data from recorded conversations between romantic couples show that face-to-face co-rumination influences people’s real-time emotional trajectories in complex ways. Furthermore, observer-ratings of the conversations suggest that third-parties can detect co-rumination, even from silent videos. Finally, I study how people react to others’ negative mood and co-rumination in a real social context by longitudinally following two cohorts of students and modelling their interactions with social network analysis tools. These models show that co-rumination appears to elicit social rejection from others, implying a possible pathway to depression via loneliness imposed on the co-ruminators.

The communication of anthropogenic climate change presents many challenges, for communicators, scientists, policymakers and publics alike. Particularly difficult is the issue of uncertainty, which can include ambiguity around the phenomenon of climate change, the possible impacts of this, and the timeframe within which such impacts will be seen. Previous research has established that audiences are often averse to uncertainty, and will disregard or ignore messages that contain it. This raises a theoretical and practical question of how best to manage uncertainty in climate change communication in order to maintain audience engagement. This question was the focus of this PhD research. Specifically, the aim of this thesis was to explore the process of climate change communication from the perspectives of the scientists, communicators, and the recipient. I achieved this research goal by utilising a mixed methods design. I firstly interviewed the originators (i.e., scientists) and professional communicators of climate change information to explore the process from their side (Chapter 2). This revealed a number of themes connecting to the different ways scientists and communicators understand the process of communication (e.g., as information exchange versus relationship building), the challenges of climate change communication and uncertainty in particular, and the (appropriate) role of scientists when communicating with the public about climate change. Next, in a series of studies I experimentally explored how audiences respond to variations in the informational content of climate change messages (such as the level of uncertainty) and the role of different communicative styles in further shaping audience engagement (Chapter 3). Broadly, the results of these studies suggest that while uncertainty can undermine audience engagement with climate change communications, the negative effects of uncertainty are buffered when the communicator is perceived to be high in morality and/ or when they use an open communication style. Interestingly, these effects of communication style were particularly evident among women, whereas men tended to react against this. Together, these studies show how relational factors (e.g., communication styles and perceptions of communication sources) can moderate the impact of informational content on audience responses. Finally, I ended this programme of research by looking in more detail at how audiences perceive a real scientific organisation engaged in climate change communication and the bases of their beliefs about organisation competence and morality (Chapter 4). This study combined qualitative and quantitative data to delve deeper into some of the insights gained in the experimental work, and to reconnect this to the real-world organisation context I began with. This study again showed how perceptions of communicator morality moderate responses to uncertainty, but also provide useful insights into the different origins of perceptions of morality and competence. Chapter 5 concludes by summarising the research presented in this thesis, discussing its strengths, limitations and ways forward. Here, I also consider the theoretical, methodological and practical implications of the thesis’ research findings. Briefly, it is argued that addressing the scientific uncertainties of climate change may not necessarily mean altering the form of information itself. Rather, modifying the language peripheral to the information that contains uncertainty, attending to the ways in which audiences perceive the sources of uncertainty, and considering variations amongst publics, may help to engage in effective communication around the complex issue of climate change.

The State of Arizona is under pressure to expand mental health services. Task Forces have been formed to look at several special population groups. This paper is designed to support a Governor's Task Force on the mental health needs of the elderly. Based on a literature review, it is clear that older persons experience significant rates of mental illness. However, current mental health services for the elderly are minimal and their needs for these services remain hidden because of myths and prejudices that are held by health and mental health professionals and the elderly themselves. The need for mental health services for the elderly is defined. Barriers to meeting that need are identified and recommendations for state and local action to improve mental health services for the elderly are presented.

The purpose of this study was to explore the feasibility of determining acculturation in a Deaf Navajo Indian through an assessment of art work, accompanying narratives, and interview data. It was concluded that the cultural characteristics of the subject examined in this case study were reflected in his art work and stories, with his Navajo identity revealed as the primary cultural affiliation. Interview data indicated the presence of a significant, albeit less predominant, Deafness cultural affiliation that was not notably reflected in the art pieces or accompanying narratives. Art therapy alone was not established as a reliable medium through which to assess acculturation. However, used in concert with the interview and the subject's own narratives, art therapy proved to be of value in the assessment of acculturation patterns in a Deaf Navajo Indian.

The incidence of HIV infection has been increasing among Hispanic women at an alarming rate. An assessment was conducted concerning attitudes and behaviors about sex and safe sex practices of 28 young Hispanic women attending an alternative education program in South Tucson, Arizona. This study sought to discover if relationships exist between: HIV education and safe sex practices; level of acculturation and safe sex practices; and attitudes and safe sex practices. Findings were inconclusive regarding the association between level of acculturation and safe sex practices. HIV transmission knowledge does not appear to influence safe sex practices. However, several of the attitudes investigated do appear to influence safe sex practices.

Cancer during the twentieth century has become a major universal health concern. The American Indian population, too, has experienced both a dramatic rise in cancer rates and different patterns of cancer among tribal groups. The purpose of this thesis is to discuss various factors including culture that impact cancer in American Indian populations. A literature review that provides cancer data, including rates, risk factors, and American Indian responses to cancer is presented in the opening chapters. In addition, results of a qualitative exploratory research involving a sample from the Pasqua Yaqui Tribe of Southern Arizona and a non-Indian sample from the Community Hospice Program of Tucson are presented. Data from both groups are analyzed, compared, and summarized.
