Predictors Of Canadians’ Psychological Well-Being In Retirement: A Mixed Methods Approach, Jessica Miller

Theses and Dissertations (Comprehensive)

In prior decades, retirement research focused on the negative effects of the life transition—such as negative psychological well-being caused by factors such as difficulties adjusting to retirement, feelings of a role loss, or the financial effects of retirement. However, there is considerable agreement across recent research studies that post-retirement years are marked by positive psychological well-being due to a variety of factors. For example, retirees often spend more time in roles (such as volunteer positions) that provide life satisfaction. The present study uses both quantitative and qualitative methods to examine factors related to well-being in retirement among individuals living in …

Grammatical Aspect, Temporal Adverbs, And Situation Models, Valerie Hemeon

Theses and Dissertations (Comprehensive)

Grammatical aspect and temporal cues have been shown to impact discourse processing. To explore this further, we contrasted temporal adverbs that move narrative timelines forward or backward. Although previous research has examined timelines independently, it was yet to be explored how timeline adverbs impact discourse processing when grammatical aspect and temporal cues are also manipulated. The experiment involved a sentence-completion task which allowed us to measure availability of target discourse concepts in situation models. Results showed main effects for grammatical aspect, temporal shifts, and narrative timeline directions. Three two-way interactions were found. The results demonstrated support for the iconicity assumption …

The Influence Of Visual Perspective On The Cognitive Effort Required For Mental Representation, Jeffrey P. Hong

Theses and Dissertations (Comprehensive)

Mental representation is the process by which an individual simulates an event in their mind’s eye. This process is the foundation of the ability to remember the past, engage in prospective thinking, or imagine fictitious scenarios. An individual can mentally represent any event through their own eyes—the first-person perspective or from the viewpoint of an external observer—the third-person perspective. The perspective of representation influences outcomes related to memory, visuospatial processing, affect, social cognition, clinical diagnoses, and language processing. In turn, an individual’s tendency to favour either perspective is shaped by related factors.

The current research consists of four experiments, designed …

Workplace Wellbeing And Sense Of Mattering Among Small And Medium Enterprise Workers In Canada, Kyle Smilovsky

Theses and Dissertations (Comprehensive)

Small and Medium Enterprises (SME) are an under researched area when it comes to workplace wellbeing in Canada. The current research used the Job-Demands Resource Framework (JD-R) to study how a Community Psychology concept, sense of mattering, relates to workload, and indicators of wellbeing (i.e., burnout and flourishing). Specifically, this study tested whether sense of mattering moderates the association between workload and both burnout and flourishing. Moderated mediation models were also tested to see if workload is indirectly associated with burnout and flourishing through distress, while being moderated by sense of mattering. Questionnaires were administered to 2,500 Canadian SME workers …

Dancing Around And Through Harm: Examining The Lived Experiences Of Women Of Colour With Gender-Based Violence In The Toronto & Kitchener-Waterloo Latin Dance Communities, Lexi Salt

Theses and Dissertations (Comprehensive)

Given the systemic nature of gender-based violence in Canada, as well as the increasing popularity of Latin dance, it is important to better understand the particular and culturally-specific ways gender-based violence manifests itself within the Latin dance community. This research study examines the lived experiences of women of colour with gender-based violence in the Toronto and Kitchener-Waterloo Latin dance communities. Two groups of participants took part in semi-structured interviews: 14 women of colour dancers, and six “Power Players”, leaders in the Latin dance community who are in a position of power (e.g., instructors, organizers, DJs). The data was analyzed using …

A Close Look At The Connections Between Mental-State Talk, Theory Of Mind, And Source Monitoring During Parent-Child Reminiscing Of Emotional Events, Mallory Earnshaw

Theses and Dissertations (Comprehensive)

Autobiographical memories play a critical role in shaping personal identity, regulating emotions, and guiding future behaviour. Reminiscing about these memories can be particularly beneficial for coping with negative experiences. This study investigated the connections between mental-state talk, theory of mind, and source monitoring in parent-child reminiscing, and how it can be influenced by remembering enjoyable versus frustrating events. This study involved children ages 3-8 (N = 50) and consisted of two sessions. In the first session, the child reminisced with their parent about an enjoyable and frustrating event and completed two source-monitoring tasks. In the second session, the child …

Examining The Effects Of Noise And Task Dependent Performance In Prosody Perception In Autistic Individuals, Zehranur Sasal

Theses and Dissertations (Comprehensive)

ABSTRACT

Objective: It is known that autistic individuals have enhanced abilities in pitch discrimination and tend to excel in low-level tasks requiring lower cognitive processing. On the other hand, noise is a distracting factor in many areas of life, including prosody perception. The studies presented in this thesis aimed to understand prosody perception through different levels of cognitive tasks and under the influence of speech background noise.

Methods: In total, 256 non-autistic and 39 high-functioning autistic adults participated in these studies. In the first study, participants were asked to listen to brief utterances conveying one of six universally accepted emotions …

Empathy In Police Officers Undergoing De-Escalation Simulation Training: A Comparison Between Virtual Reality And Live Action Modalities, Jacqueline Kohl

Theses and Dissertations (Comprehensive)

This study compared empathy among police officers undergoing mental health crisis de-escalation training in virtual reality and live action training modalities. The study included police officers across different police services in Ontario (N=63) and evaluated the efficacy of the Mental Health Crisis Response Training (MHCRT, Lavoie et al., 2020) program delivered across virtual reality and live action modalities against a control group that did not receive the training program. After collection of participants’ demographics, empathy scores, and de-escalation competency scores, a series of correlations, ANOVAs and ANCOVAs were conducted. Results showed that participants receiving MHCRT virtual reality and …

Distinctiveness And Similarity: How The Sub-Trait Facets Of The Big Five Self-Organize To Create Personality Types, Jonathan Thiessen

Theses and Dissertations (Comprehensive)

The belief that people can be placed within a personality typology has persisted for millennia. At least as far back as Hippocrates (ca. 460 BCE–370 BCE) people were believed to be of a kind based on the four humors—blood, yellow bile, black bile, and phlegm. Since then, there have been many conceptions of personality typologies. The Myers-Briggs Type Indicator and the Enneagram of Personality are likely the most well-known personality typologies among the general public. Despite their wide public usage, neither typology boasts strong empirical support. However, psychology continues to investigate personality for evidence of a typology of personality. In …

The Long-Term Effects Of Cannabis On Attention To Motion, Rachel Mccaig

Theses and Dissertations (Comprehensive)

The purpose of the following study was to investigate the long-term effects of cannabis use on attention to motion.

Methods: Cannabis users, who varied in age of onset of use, were compared to control participants after abstaining from cannabis for at least 24 hours. One-hundred and ninety-seven participants engaged in a cognitive assessment followed by a motion discrimination task and an attention to motion task. The assessment consisted of a series of standard tasks that measured a range of cognitive processes such as attention, memory, and executive functioning. The motion discrimination task assessed the participants’ abilities in discriminating between various …

Intermittent Sucrose Access: Sweetness Versus Calories, Jarret Folmer, Rudy Eikelboom

Theses and Dissertations (Comprehensive)

Nondeprived rats receiving every 3^rd day access (E3DA) to 4% sucrose solution consume more sucrose on access days compared to rats with everyday access (EDA). Rats receiving EDA or E3DA to 16% sucrose do not consume different amounts, but if placed on every 2^nd day access (E2DA) to 4% sucrose E3DA-group rats consume more than EDA rats (Eikelboom, Hewitt, & Adams, 2022). E3DA affects rats’ value of sucrose but effects appear hidden with high sucrose concentrations. Valyear and Eikelboom (2021) suggested that calorie ceilings limit E3DA-induced consumption with high sucrose, but this ceiling could also be caused by …

Ethical Dilemmas And Moral Distress In Companion Animal Veterinary Medicine: Mental Health Implications, Bronwyn Dickson

Theses and Dissertations (Comprehensive)

Mental health concerns are a significant problem in the veterinary community, and studies suggest that veterinarians working in Western countries are at higher risk of suicide compared to the general population and other healthcare professionals (Bartram et al., 2009; Bartram & Baldwin, 2010; Platt et al., 2012). Additionally, veterinary medicine is an occupation inundated with complex ethical and moral dilemmas. However, current studies are limited in their ability to contextualize the risk and contributing factors fully; therefore, they offer limited insight into effective preventative and support strategies. Using Interpretive Phenomenological Analysis (IPA), eight companion animal veterinarians were interviewed about their …

Still, We Thrive: Understanding How Gay, Bisexual, Transgender, And Other Men Who Have Sex With Men (Gbtmsm) Experience Structural Barriers & Facilitators To Wellness, Lucas Gergyek

Theses and Dissertations (Comprehensive)

Historically and concurrently, structural violence has been a significant force influencing the sexual health and broader health of gay, bisexual, transgender and other men who have sex with men (GBTMSM). Yet to date, the majority of projects exploring the health inequities facing GBTMSM have focused on intrapsychic and behavioural factors as most related to poor health outcomes. As well, these studies are sometimes deficits focused, and fail to evaluate how GBTMSM continue to thrive, and maintain positive health. As a result, the ways in which systems and policies underlie and perpetuate health inequities facing GBTMSM have been somewhat obscured. Connectedly, …

Transformations Towards Just Urban Sustainabilities: A Community Psychology Approach To Analyzing And Fostering Urban Changes, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

Cities are uniquely positioned to drive social change towards more just and sustainable futures. However, while discourses of ‘transformations towards sustainability’ have gained prominence, their focus on integrating equity and justice and tackling the root causes of current unsustainabilities is lacking. This document outlines a research endeavor aimed at analyzing and fostering urban sustainable transformations from a community psychology perspective. This research is based on the assertion that without radical change based in equity and justice considerations, transformative efforts fail. First, a theory of just urban sustainable transformations (JUST) is suggested that draws on urban transformations and just sustainabilities scholarship. …

Vapourized Cannabis Extract Administration Impairs Memory And Alters Neural Activity In Laboratory Rats, Megan Chladny

Theses and Dissertations (Comprehensive)

Although people have smoked cannabis for millennia, administration of cannabis by heating the dried plant material or distilled extracts to a temperature just below the combustion point (i.e., vapourization or "vaping") has rapidly increased over the past few years (Javadi-Payder, Cole, and Taffe, 2018; Manwell, Charchoglyan, Brewer, Matthews, Heipel, and Mallet, 2014). Conversely, most of the cannabinoid research using rodent models has used parenteral routes of administration to examine the effects of purified cannabis extracts such as ∆⁹-tetrahydrocannabinol (THC), making it difficult to directly compare laboratory research to human drug use. Building on previous studies showing that THC …

Inspirational Bullshit: The Good, The Bad, And The Vacuous, Esther Abel

Theses and Dissertations (Comprehensive)

There are myriad methods offered in the “self-help industry” and on social media promising to improve happiness. Some messages are evidence-based, often drawn from positive psychology research, and suggest actions requiring time and effort, while other messages may offer feel-good platitudes that are devoid of meaningful guidance; we label this latter type of content “inspirational bullshit.” Across two manuscripts, we investigate the predictors of liking different kinds of positive self-help content, from meaningless randomly-generated phrases to vacuous positivity to evidence-based advice. In the first manuscript, across three studies, bullshit receptivity (a tendency to judge pseudo-profound statements as profound) and people’s …

Water Stories: An Exploration Of Human-Water Connectedness In Ontario And The Implications For Water Sustainability, Tracey Ehl

Theses and Dissertations (Comprehensive)

Abstract

Water is the great connector. Water connects people, health, wellness, culture, spirituality, nature, and the economy. Clean, safe water (potable water) and sanitation were recognized over a decade ago by the United Nations General Assembly (UN) as a basic human right, and more recently the UN has also identified water sustainability and management as one of 17 sustainable development goals for all people in all countries. Water is inextricably connected to humans. Yet, in Ontario, Canada, a place with access to some of the largest freshwater reserves in the world, robust regulatory frameworks, involvement, some investment by all levels …

The Contribution Of Phonological Overlap To The Cognate Effect: An Event-Related Potential Study Of Persian-English Bilinguals, Zahra Fotovatnia

Theses and Dissertations (Comprehensive)

The purpose of this dissertation was to examine the contribution of phonological overlap to visual word recognition. More specifically, this study aimed at testing the phonological account of the cognate effect (i.e., faster and more accurate mental processing of cognates than noncognates) in visual word recognition in Persian and English, which are languages with different scripts. The phonological account attributes the cognate effect to the phonological similarity of cognates (form and semantically related words) in addition to the conceptual similarity that cognates and noncognates (semantically related words) have and to the degree of phonological similarity between cognates in two languages. …

The Power Of Dissent: Mitigating False Polarization And Cross-Party Dislike In Online Interactions, Victoria Parker

Theses and Dissertations (Comprehensive)

While actual polarization is on the rise in the United States, perceived polarization (i.e., false polarization) is growing at an even faster rate, contributing to increased cross-party hostility. A meaningful amount of out-party dislike may be produced by partisans’ dramatic overestimates of the prevalence of extreme, undesirable views among political opponents. In the current research, we examine whether exposing people to out-party dissenters who challenge their copartisans’ extreme views might help reduce people’s misperceptions of their opponents’ extreme views, and possibly mitigate animosity. Across five studies (N = 3789), we explore how seeing public ingroup dissent (in the form of …

Investigating The Role Of Implicit Theories Of Relationships On The Interpretation Of Investments In Relationship Decision-Making, Sarah Wall

Theses and Dissertations (Comprehensive)

A person’s prior investment in their romantic relationship is a strong predictor of whether they remain committed to that relationship (e.g., Le et al., 2010; Rusbult, 1980a; 1983), and this pattern is often seen outside of interpersonal contexts as well (e.g., Arkes & Blumer, 1985; Olivola, 2018; Thaler, 1980). However, little research has considered the extent to which commitment-relevant decisions might be affected in a top-down way by people’s implicit theories of relationships (ITRs; Knee, 1998). I theorized that lay theories about how relationships work may affect the extent that people consider past investments when making decisions about continuing with …

“I Wonder If Being Broke Is Worth It For School”: An Investigation Of The Relationship Between Anxiety, Well-Being, And Coping Strategies Among Undergraduate Students During The Covid-19 Pandemic, Rebekah Woodburn

Bridges: An Undergraduate Journal of Contemporary Connections

This study investigated the relationship between stressors, coping strategies, and well-being among undergraduate students during the COVID-19 pandemic. Undergraduate students were asked to complete a series of measures designed to assess their general health levels, financial anxiety, subjective well-being, and resilience. In addition, they were asked open-ended retrospective questions regarding the coping strategies they had used over the course of the school year and the perceived effectiveness of these strategies. It was hypothesized that stress would be prevalent among many undergraduate students who face moderate to high anxiety levels. They would use inadequate coping strategies to improve their emotional well-being. …

Improving Adult Sex Offender Rehabilitation With Strength-Based Approaches, Jennifer Kirshenbaum

Bridges: An Undergraduate Journal of Contemporary Connections

New approaches in any field require analysis. In forensic psychology, strength-based approaches are a relatively new approach used with a variety of offenders, but most especially with adult sex offenders. The goal of this literature review is to understand, through the unification of many research papers, how and why strength-based approaches provide more efficient programs and reduced recidivism for this population. While including a statistical background of adult sex offenders in Canada and a history of all the models discussed, the central tenet of this paper is that despite considerable academic debate, RNR and CBT models work well, but they …

Community Stress And Resilience During Covid-19: Assessing The Emotional Profile Of The City Of Hamilton Using A Social Media Analysis, Senyo Agbeyaka

Theses and Dissertations (Comprehensive)

This study investigated stress and resilience at the neighbourhood level in Hamilton Ontario in pre- and peri-pandemic conditions using a social media analysis. Sentiment analysis of geo-located Twitter posts produced within Hamilton census tract boundaries was conducted using Stresscapes and EMOTIVE, validated software that extract and code emotional information from human language expressions about stress and hope (a proxy for stress), respectively. Baseline levels of both emotions were measured using aggregate scores at the census tract level in Hamilton from tweets produced during two pre-pandemic periods (March 2019 to July 2019; and August 2019 to February 2020), with a replication …

Thinking About Making A Connection: Exploring The Role Of Metacognition In Recognition Memory For Associative Information, Mario E. Doyle

Theses and Dissertations (Comprehensive)

In a set of six experiments, the relation between metacognition and associative memory was explored. The purpose was to determine whether the metacognitive behaviors that are used with item memory are also used with associative memory. Different memory systems have separate underlying processes which can cause mnemonic strategies to only be useful for some types of memory. People use metacognition to monitor and control their memory; however, it is uncertain whether metacognitive monitoring and control are the same for different types of memory. The research presented in this dissertation demonstrates the similarities and differences between metacognitive behavior for item and …

Relationships Between Executive Functioning, Memory, And Source Judgements On Children’S Responses To Online Advertising, Samantha Barbosa

Theses and Dissertations (Comprehensive)

Children’s understanding of online content is a topic of interest, yet little is known about how children distinguish distracting and often misleading information (e.g., advertisements) from relevant information. Our aim is to measure the relationship between executive functioning, memory and source monitoring in a population that has heavy internet usage and are also the most at risk for mistakenly recalling false or irrelevant information. Children aged 7-12 years old (N = 30), with no known developmental or cognitive disorders, were recruited for the study. In an online session, the children viewed two novel online media sources (i.e., a website …

The Untended Garden: How Adoptees Navigate Relationships With First Family Members, Dawn Michele Mccormick Tracz

Theses and Dissertations (Comprehensive)

This research explores how people who were adopted over the age of 6 years old in open adoption arrangements navigate ongoing relationships with first family members. It explores perceptions of how a connection with both adoptive and first family members impacts self-concept. Using an interpretivist-constructivist lens, the narratives of four women are presented and analyzed. In addition to qualitative interviews, each participant was invited to create images that represented relationships with significant family members. The narratives are re-presented in detail adhering closely to the teller’s organization and emphases. In the analysis, themes related to relationships with first family members and …

Feeling Fat: Theorizing Intergenerational Body Narratives Through Affect, Katie Cook

Theses and Dissertations (Comprehensive)

This study set out to understand the intergenerational movement and impact of obesity epidemic and anti-fat narratives that emerged after the 1950s in North America. Embedded in an Anglo-Western, neoliberal context, the current study sought to understand the impact of weight-based messaging on the embodied experiences of parents and their now-adult children. Working within a critical-transformative paradigm and drawing on post-humanism and new materialism, I conducted 19 narrative interviews with individuals born between 1955 and 1990, six of whom were mother-daughter dyads, as well as a body mapping workshop with five self-selecting participants over the course of three sessions. I …

"If We're Not Loud, We're Not Cared For": Empowerment In Transgender Peoples' Healthcare Experiences, Chase Valiant

Theses and Dissertations (Comprehensive)

Healthcare plays a crucial role in the health and quality of life of transgender (herein trans) people. The experiences people have when accessing healthcare, can have significant effects on future interactions with the healthcare system as well as individual health outcomes. The purpose of this study was to gather insights into trans peoples’ positive healthcare experiences and health outcomes through the lens of empowerment. Fifteen interviews with trans men and trans women were drawn from a larger study of trans peoples’ experiences of discrimination. Thematic analysis was undertaken to identify key themes in the data. Experiences of empowerment were facilitated …

The Electrophysiological Correlates Of Text Integration And Direct Vs. Indirect Articles: A Centralized And Lateralized Examination, Deanna C. Hall

Theses and Dissertations (Comprehensive)

As we read, we develop mental models of the discourse content called situation models. Situation models are integral to how we keep track of information, and to do so in an ongoing event incoming information needs to be integrated into the model or discarded. The type of information being presented, and its relation to prior data, impacts how that new information is processed. The current research examined discourse passages containing concepts that were either previously mentioned (match), mentioned with a general term (general category), unmentioned in lieu of another concept (mismatch), or completely unmentioned previously (indeterminate), and examined how these …

Impact Of Inducing Self-Compassion On The Use Of Safety Behaviours In Social Situations, Kamila Szczyglowski

Theses and Dissertations (Comprehensive)

Safety behaviours are commonly used in an attempt to decrease anxiety experienced in social settings. These behaviours, however, have been found to maintain anxiety. Self-compassion has shown promise for reducing anxiety and post-event rumination. The aim of the present studies was to examine the impact of a self-compassion induction on safety behaviours. It was hypothesized that inducing self-compassion would lead to lower safety behaviour use compared to control conditions. For the first two studies, participants were randomly assigned to complete self-compassion inductions or control writing prompts in relation to imagining a pre-determined social situation. Study 3 followed a similar procedure …
