I Think, Therefore I Can: Self-Efficacy, Self-Regulation, And Sense Of Belonging In Introductory Physics, Danielle Christine Maldonado

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cognitive and affective beliefs in physics classrooms are important indicators of student success beyond traditional measurements of academic performance. This body of work explores major beliefs and processes, including self-efficacy, self-regulation, and sense of belonging, as they relate to academic achievement among introductory undergraduate physics students. First, this dissertation explores the development of physics self-efficacy and physics sense of belonging, two highly correlated variables. This work identifies unique sources of physics self-efficacy and sense of belonging development from current and prior academic experiences, personality factors, and demographic variables. Then, relationships between early- semester self-efficacy and sense of belonging, mid-semester …

Personal Narratives Of Young Adults With Epilepsy: Exploring The Transition To Adulthood Amidst Stigma And Disclosure Fears, Kirby-Estar Gilene Laguerre

Graduate Theses, Dissertations, and Problem Reports (ETD)

Navigating the transition to adulthood presents unique challenges for young adults with epilepsy, particularly concerning stigma and the fear of disease disclosure. While significant social difficulties, such as increased unemployment rates and decreased relationship satisfaction, are prevalent among individuals with epilepsy, current transition programs often fail to address these psychological and social aspects that are vital for an independent adult life. Instead, the majority of the attention for young adults transitioning into adulthood is focused on the shift to adult-oriented healthcare systems. Consequently, there is a critical need for research that goes beyond a healthcare focus and explores the social …

Influences Of Response Rate And Distribution On Accuracy Estimates: The Value Of Replications Based On Analytic Approach, Olivia Brianne Harvey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Accurate observational data are essential for drawing correct conclusions about behavioral phenomena and ensuring the replicability of research findings. Accuracy is the extent to which an observer’s recorded responses correspond with true values (i.e., the actual occurrence of behavioral events). Correspondence is quantified using one of several percentage-based algorithms. However, these accuracy estimates may be influenced by characteristics of the data, such as response rate and response distribution, as well as the algorithm used to calculate them. The purpose of this dissertation was to evaluate how response rate, response distribution, and the algorithm used to evaluate accuracy influences estimates. Across …

Effect Of Delay On Reinforcer Preference And Efficacy, Ciara Jasmine Rodriguez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Behavior intervention plans are used to increase desired behavior and decrease problem behavior, and these plans require the use of effective reinforcers. High-quality reinforcers that are delivered immediately tend to be the most effective, but optimal reinforcement parameters are not always feasible or appropriate in applied settings. Some reinforcers may be disruptive, teachers’ competing responsibilities may introduce delays to reinforcer delivery, and reinforcers may not be immediately accessible. Stimuli may lose their reinforcing value with delay to their receipt, and this is referred to as delay discounting. Thus, there is likely a point where a less preferred but immediately delivered …

Dispositional Mindfulness And Autonomic Reactivity, Thomas Dylan Boyer

Graduate Theses, Dissertations, and Problem Reports (ETD)

To explain how different facets of mindfulness were associated with task performance in distinctive ways, Lindsay and Creswell (2017) proposed the Monitor and Acceptance Theory (MAT). According to this model, the mindfulness facet of monitoring present state awareness was thought to influence task performance differently than the nonjudgmental acceptance facet of mindfulness, but no studies to date have examined this model with respect to an individual's physiological response to stressful tasks. Because dispositional mindfulness has been associated with both increased and decreased physiological and affective reactions to stress in previous studies, the present study tested whether the Monitoring facet of …

Psychometric Assessment Of The Ambivalent Ageism Scale: Investigating Measurement Invariance And Stability Across Groups And Time, Carly Pullen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The goal of the current study was to examine the psychometric properties of the Ambivalent Ageism Scale (Cary et al., 2017) and to provide an understanding of how ageist attitudes might change or remain the same in response to a cultural and societal event. Measurement invariance is the assessment of the psychometric equivalence of a construct (e.g., ageism) across groups or waves of measurement (Putnick & Bornstein, 2016). The first step in measurement invariance analyses is configural measurement invariance, which is the evaluation of the factor structure, with the goal of producing the same number of factors and the same …

The Bleeding Edge Of Misogyny: How Gender-Based Harassment And Infrastructural Neglect Shape Menstrual Distress, Mackenzie J. Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite growing attention to menstrual health, organizational research has largely overlooked how workplace conditions shape menstrual experiences. Dominant perspectives frame menstruation as an individual issue that negatively affects work, neglecting how features of the work environment – such as gender-based harassment and access to menstrual-related infrastructure – contribute to menstrual distress. Addressing this gap, this dissertation adopts a bidirectional perspective, examining how social and material workplace conditions shape menstrual distress, defined as the extent to which menstrual symptoms interfere with daily functioning. Drawing on the transactional model of stress and objectification theory, I hypothesized that gender-based harassment would predict menstrual …

Early Life Adversity And Reward Reactivity In Humans, Maria C. Potts

Graduate Theses, Dissertations, and Problem Reports (ETD)

Both animal and human research has identified early life adversity (ELA) as a prominent risk factor for substance use disorder (SUD). However, the underlying mechanisms linking ELA to SUD development remain unclear. Animal studies point to differences in reward responsiveness as the primary explanation; specifically, that ELA could lead to individual differences in the attribution of incentive salience to reward-predictive cues, or the “sign-tracking” behavioral phenotype. Sign-tracking has been linked to addiction-related behaviors in both animal and human studies, but no human studies have examined whether sign-tracking could partially explain the link between ELA and SUD. In fact, human studies …

Operationalizations Of Adverse Childhood Experiences And Health Prediction, Sarah Josephine Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Exposure to adverse childhood experiences (ACEs) has been consistently linked to suboptimal health outcomes and behaviors across the lifespan. As such, there has been widespread adoption of measures like the 10-item cumulative ACEs count measure developed by Felitti and colleagues (1998) across research literature and clinical practice. However, this measure was not developed with consideration of optimal psychometric properties and thus consists of several limitations that inhibit understanding of the specific dimensions of adversity that influence health outcomes. This 3-study dissertation focused on different measurement and statistical techniques to better understand the associations between ACEs and health. In study 1, …

Be A Man: Hypermasculinity And Hostile Attribution Bias As Predictors Of Violence, Kaley Nicole Potter

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, violence has risen to record-high numbers in communities and correctional facilities, with men perpetrating the vast majority of violent crimes. Hypermasculine values (e.g., power, aggression, and domination) have been linked to aggressive and violent behavior. Hostile attribution bias, which leads individuals to attribute hostile intent to neutral or ambiguous stimuli, has also been linked to aggression.

The current study used structural equation modeling (SEM) to examine hypermasculinity and hostile attribution bias as predictors of proclivity for violence, comprised of aggression and historical violence. The model was iteratively modified to assess changes in model fit and constructs. Male …

Accessing Campus Mental Health Services In A Nigerian Southwestern University: Barriers To Academic Success, Caroline Dada

Electronic Theses and Dissertations

Mental health disorders are a significant health concern among higher education institutions in sub-Saharan Africa, including Nigeria. A substantial treatment gap exists in the Nigerian healthcare system, and this gap is further worsened by cultural and religious barriers, which reinforce stigma that discourages students from seeking professional help. This qualitative narrative inquiry explored the barriers students encountered when accessing mental health services at a university in Southwestern Nigeria, to increase service access. Qualitative semistructured interviews were conducted with seven professional mental health providers at a university counseling center between March and April 2025. Inductive thematic analysis was used to identify …

Exploring Parent-Child Reminiscing Style And Internal-State Talk When Discussing Positive And Negative Shared Events, Komal Verma Miss.

Theses and Dissertations (Comprehensive)

Conversations between parents and children about past events play a critical role in children’s social, emotional, and cognitive development. Parents scaffold their children in learning to recount details of their autobiographical memories by creating a space to reflect on internal states, specifically emotions and cognitions. Parents with an ‘elaborative’ reminiscing style are responsive to children’s utterances and ask open-ended questions (e.g., What do you remember about...?). Parents who are less ‘elaborative’ typically ask narrow questions like Did you like it?” that do not encourage conversation. Children whose parents use an elaborative reminiscing style have children who produce the most detailed …

Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski

Theses and Dissertations (Comprehensive)

This thesis addresses how animals cope with unpredictability by testing how environmental stability changes the behaviour of zebrafish (Danio rerio) in two complementary experiments. In Experiment 1, fish lived for three months in either a Dynamic environment (water temperature, feeding times, habitat complexity, group size, and membership fluctuated) or a Stable environment (all factors constant). Across seven behavioural assays, measuring individual behavioural differences, collective movement, social memory, and information use, Dynamic condition fish were found to be more sensitive to social cues and more likely to conform to recent social information, independent of the quality of the information …

Neural Correlates Of Cognitive Fatigue In Regular Cannabis Users And Non-Users: A Pilot Fnirs Study, Mariia Vistyzenko

Theses and Dissertations (Comprehensive)

Background: Cognitive fatigue impairs performance across multiple domains, yet how regular cannabis use affects fatigue responses remains unclear. This pilot study investigated neural and behavioural correlates of cognitive fatigue in abstinent cannabis users versus non-users.

Methods: Twenty-six participants (18 non-users, 8 regular cannabis users after 24-hour abstinence) completed cognitive tasks before and after a 60-minute Sustained Attention to Response Task (SART) designed to induce fatigue. Tasks assessed working memory (N-Back), cognitive flexibility (Wisconsin Card Sorting), psychomotor speed (Digit Symbol Substitution), sustained attention (Continuous Performance Task), inhibition (Stroop, Stop Signal), and motion perception. Functional near-infrared spectroscopy (fNIRS) continuously monitored prefrontal cortex …

Moral Identity And Cognitive Mechanisms In Moral Decision-Making, Zachariah I. Hamzagic

Theses and Dissertations (Comprehensive)

Moral identity can be broadly conceptualized as the degree to which an individual places moral values as directly relevant to their personal identity. A recently introduced developmental framework of moral identity argues that moral identity can be conceptualized as a lifelong goal. According to this theoretical framework, the moral identity goal (i.e., to be a moral person and engage in moral action) becomes stronger over the course of development by becoming more abstract (i.e., general), internalized (to satisfy personal ideals) and promotion (i.e., action) oriented. Additionally, the strength of the moral identity goal predicts moral functioning. To date there has …

Unveiling Othering Experiences In Multiethnic Families: Narratives Of Identity And Belonging Among White/Hispanoamerican Women, Maria-Esther Wood

Using qualitative narrative inquiry, the study centres the voices of nine women residing in Ontario, each with one white parent and one Hispanoamerican parent, ranging in age from 19 to 65. Guided by Dewey’s three-dimensional model of narrative analysis, the research explores how personal stories reflect broader patterns of othering and belonging, the central research question asks: What specific forms of othering related to identity and belonging—inclusive of discrimination and racist treatment—do multiethnic Hispanoamerican women …

The Forgotten Carers: A Study Of The Lived Experiences Of Chinese Canadians Caring For A Family Member With Borderline Personality Disorder (Bpd/Fbpd), Judy Y.F. Wu

Theses and Dissertations (Comprehensive)

There is a fair amount of literature on Borderline Personality Disorder (BPD); however, it still lags behind research on other major mental illnesses such as depression and schizophrenia (Furnham et al., 2015). Similarly, while there has been ample research on caring from various perspectives; little has been explored regarding caring for individuals with BPD. Research on Chinese Canadian families caring for patients with BPD is even more scarce. This study explored the lived experiences of Chinese Canadians caring for family members diagnosed with BPD (FBPD) in the Greater Toronto Area (GTA), Ontario, Canada. BPD is characterised by “interpersonal hypersensitivity, affective …

Picturing Your Goals: Examining Imagery Perspective And Self-Concordance In Goal Motivation, Cana J. Reuber

Theses and Dissertations (Comprehensive)

Mental imagery is often used as a strategy to increase motivation and support goal pursuit, but it remains unclear when different forms of imagery are most effective. Prior work suggests that adopting a third-person imagery perspective may enhance goal striving by promoting more abstract, identity-relevant processing. In line with this work, we predicted that third-person imagery would be most beneficial for self-concordant goals. The present research tested this prediction across three studies. In Study 1 (N = 273), participants identified a personal goal, visualized themselves pursuing and attaining it from either a first- or third-person perspective, and reported their …

Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.

Theses and Dissertations (Comprehensive)

Cognition is widely believed to be adaptive, yet few studies directly show that variation in cognitive performance is related to fitness. Brown-headed cowbirds (Molothrus ater) provide a powerful system for addressing this gap because brood parasitism creates strikingly different reproductive problems for females and males. Females face the spatial demands of nest-prospecting, whereas males face social and competitive demands associated with access to mates. Across five experiments, cowbirds were tested on an outdoor foraging task designed as an analogue of nest prospecting, with manipulations of retention interval, cue conflict, and breeding condition, followed by observations of reproductive behaviour. …

Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch

Theses and Dissertations (Comprehensive)

BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …

The Effects Of Appearance Change And Partial Face Visibility On Eyewitness Identification, Raina-Lynn A. Brock M.A., Judy Eaton Ph.D.

Theses and Dissertations (Comprehensive)

There is limited research examining the possibility of a temporary appearance change (e.g. a black eye) between exposure to a perpetrator at the time of a crime and later identification attempts by eyewitnesses. Across two experimental studies, this research examines how eyewitness identification decisions are impacted by an appearance change and how lineup procedures can influence eyewitness accuracy. Study 1 examined how a transient facial feature, a black eye, affects the accuracy of eyewitnesses’ identification decisions, while manipulating the severity of the black eye (prominent bruising, faded bruising, no bruising). Participants (N=403) were exposed to a 43-second mock crime video …
