The Neural And Cognitive Basis Of Cumulative Lifetime Familiarity Assessment, Devin Duke May 2016

The Neural And Cognitive Basis Of Cumulative Lifetime Familiarity Assessment, Devin Duke

Electronic Thesis and Dissertation Repository

Perirhinal cortex (PrC) has been implicated as a brain region in the medial temporal lobes (MTL) that critically contributes to familiarity-based recognition memory, a process that allows for recognition to occur independently of contextual recollection. Informed by neurophysiological research in non-human primates, fMRI, as well as behavioural work in humans, the current thesis research tests the novel hypothesis that PrC cortex functioning also underlies the ability to assess cumulative lifetime familiarity with object concepts that are characterized by a lifetime of experiences. In Chapter 2, a patient (NB) with a left anterior temporal lobe (ATL) lesion that included PrC as …


Evaluation Of The Effect Of A Behavioural Coaching Intervention On Faculty Adoption Of Technology-Enhanced Teaching Practices, Nicole M. Domonchuk May 2016

Evaluation Of The Effect Of A Behavioural Coaching Intervention On Faculty Adoption Of Technology-Enhanced Teaching Practices, Nicole M. Domonchuk

Electronic Thesis and Dissertation Repository

College faculty members face increased pressure to incorporate technology into their teaching approach. However, without the support of comprehensive professional development, it is unlikely that they will adopt effective practices that enhance student outcomes. The purpose of this study was to evaluate the impact of a behavioural coaching intervention comprised of goal setting, performance feedback, modeling, instructions, and rehearsal on faculty adoption of technology-enhanced teaching practices. A small group of college faculty members (n= 6) participated in weekly coaching sessions for the duration of one academic semester. A changing criterion design was used to evaluate the effects of the intervention. …


The Dark Side Of Jealousy, Kristi A. Chin May 2016

The Dark Side Of Jealousy, Kristi A. Chin

Electronic Thesis and Dissertation Repository

A previous unpublished study found positive associations between jealousy (cognitive, emotional, behavioural) and the Dark Triad (narcissism, Machiavellianism, psychopathy) (Raheb, Atkinson, Chin, Vernon, submitted). The present study investigates whether self-esteem and entitlement mediate these positive relationships. To test this question, 453 participants (311 females, 140 males, 2 other) between the age of 17 to 81 years (M = 33.19, SD = 10.32) completed the Multidimensional Jealousy Scale, the Short-D3, the Psychological Entitlement Scale, and the Rosenberg Self-Esteem Scale. One model showed significant mediation: higher psychopathy was related to higher cognitive jealousy, and this relationship was significantly mediated by lower …

Examining Internalizing Symptoms In Child And Youth Victims Of Emotional Abuse And Bullying: The Mediating Effects Of Individual And Family Strength Factors In Clinical Samples, Amani M. Elrofaie

Electronic Thesis and Dissertation Repository

Child and youth experiences of emotional abuse and bullying are harmful interactions by caregivers and peers, which produce adverse mental health and social outcomes (Glaser, 2011). This study examined the relationships between trauma exposure and internalizing outcomes through individual and parenting level strength factors. The study comprised 1,297 child and youth participants, aged 4 to 18, from inpatient and outpatient mental health facilities across Ontario, who were administered the interRAI Child and Youth Mental Health assessment (ChYMH; Stewart, Hirdes et al., 2015) with their parents/caregivers. Generalized linear modelling (Nelder & Wedderburn, 1972) was used to determine the relationships between trauma …


Madness In The Media: Understanding How People With Lived Experience Interpret Newspaper Headlines, Da Qing Wang Apr 2016

Madness In The Media: Understanding How People With Lived Experience Interpret Newspaper Headlines, Da Qing Wang

Electronic Thesis and Dissertation Repository

There is research on media representations of mental health that suggests there is a tendency to portray mental health as problematic and those who are affected by mental illness as dangerous. It is evident there has been an increase in anti-stigma media campaigns. However, the effects of these efforts on beliefs held by members of the public has been mixed. What is most surprising from the literature is a lack of research about how people who have personal experience with mental illness interpret media messages. Individuals with and without lived experience participated in a structured conceptualization process known as concept …


The Relationship Between Different Dating Violence Profiles, Mental Health Problems And Mental Well-Being Among Canadian Youth, Kelsey E. Macdonald Apr 2016

The Relationship Between Different Dating Violence Profiles, Mental Health Problems And Mental Well-Being Among Canadian Youth, Kelsey E. Macdonald

Electronic Thesis and Dissertation Repository

The current study examined the relationships among teen dating violence, mental health problems and mental well-being in 338 adolescents aged 14-21 (54% female). Secondary data were retrieved from an evaluation of a small groups healthy relationship program. Participants were grouped into four different dating violence profiles based on self-reported perpetration and victimization: not involved, perpetrators, victims and combined. Generalized Linear Models were used to examine the similarities and differences across types on depression, anxiety, mental well-being and binge drinking. Results suggested that the victims and combined profiles experienced greater mental health problems and decreased mental well-being compared to other profiles. …


Bullying Experiences Among First Nations Youth: Identifying Effects On Mental Health And Potential Protective Factors, Caely I. Dunlop Apr 2016

Bullying Experiences Among First Nations Youth: Identifying Effects On Mental Health And Potential Protective Factors, Caely I. Dunlop

Electronic Thesis and Dissertation Repository

Bullying represents a substantial issue facing Canadian youth, and is associated with negative outcomes across domains of function throughout the lifespan. Despite significant literature examining bullying involvement among adolescents in Canada, a paucity of research explores the bullying experiences of First Nations, Metis and Inuit (FNMI) youth. This is particularly concerning, as these youth may be at higher risk for bullying and its related consequences due to the cultural marginalization and systemic inequalities experienced by Indigenous peoples nationwide. The present study aims to address this gap in the literature, examining the bullying experiences of FNMI youth, the effects of these …


Should I Stand By Or Stand Up? Differences In Bullying Bystander Decision Making, Lyndsay Masters Apr 2016

Should I Stand By Or Stand Up? Differences In Bullying Bystander Decision Making, Lyndsay Masters

Electronic Thesis and Dissertation Repository

Over 80% of students have been a bystander to bullying at school. Bystanders who witness bullying may choose to “stand up” against the bully and support the victim personally, encourage intervention from peers or adults, join in with the bullying or “stand by” passively without involvement. These decisions may be influenced by a variety of personal, social and environmental factors. This study proposes that bullying bystanders differ across specific factors according to their decision to intervene or not intervene. Archived data from a culturally-representative sample of 482 middle-school students were used and analyzed from a person-oriented approach. Data represented the …


The Impact Of Prior Experience Employees’ Perceptions And Beliefs About Workplace Policies And Practices, Michael D. Saxton Apr 2016

The Impact Of Prior Experience Employees’ Perceptions And Beliefs About Workplace Policies And Practices, Michael D. Saxton

Electronic Thesis and Dissertation Repository

Domestic violence (DV) is associated with negative consequences for victims, children, families, and even national economies. More recently, research has demonstrated that DV also has a serious impact on workers and workplaces. Less is known about Canadians’ beliefs toward the impact DV has on workers or the extent to which individuals are able to identify co-workers’ experiences of DV. Using data from a pan-Canadian sample of 7,834 men and women, the current study examined: 1) how prior experiences with DV relates to beliefs toward the impact DV has on workers, 2) how gender and age relates to beliefs toward DV’s …


Teachers’ Mental Health: The Relevance Of Emotional Intelligence In Burnout And Quality Of Life, Rebecca Hsiang Apr 2016

Teachers’ Mental Health: The Relevance Of Emotional Intelligence In Burnout And Quality Of Life, Rebecca Hsiang

Electronic Thesis and Dissertation Repository

Increasing emotional labour demands in the educational profession have negatively impacted teacher’s mental health resulting in high levels of stress, burnout, and subsequently leaving the profession altogether. The desire to improve the mental health well-being and retention rates in educators has given rise to research efforts examining individual factors that may assist in buffering the effects of an adverse occupational environment. Of particular research interest were the potential effects of self-perceived competence in emotional intelligence and individuals’ appraisal of their quality of life, on coping with occupational stressors. The current research was designed as a correlational descriptive field study to …


An Examination Of Risk Factors For Adolescent Engagement In Directly And Indirectly Self-Injurious Behaviours, Janell A. Klassen Apr 2016

An Examination Of Risk Factors For Adolescent Engagement In Directly And Indirectly Self-Injurious Behaviours, Janell A. Klassen

Electronic Thesis and Dissertation Repository

Research identifying similar and dissimilar risk factors for directly and indirectly self-injurious behaviours among adolescents is scarce. Due to the wide range of physical and mental health difficulties that may result from self-injurious behaviours, understanding differential risks is important to support at-risk adolescents. To address this gap in the literature, 541 clinically referred children and youth (ages 11-18 years old) were assessed using the interRAI Child and Youth Mental Health Assessment (ChYMH) and Adolescent Supplement. Logistic regression analyses revealed that older adolescents were at an increased risk for both direct and indirect self-injury. Moreover, adolescents who experienced high levels of …

An Exploration Of Service Needs For Adults Who Live With Fetal Alcohol Spectrum Disorder, Armush Salahadin

Electronic Thesis and Dissertation Repository

Families who care for children with disabilities feel that supports are essential. However, little is known about the support needs of adults who live with Fetal Alcohol Spectrum Disorders, and few specialized services exist to meet their needs. This study examined caregivers' perceived support needs for their children when they grow into adults. Sixteen caregivers of children aged 10 years or older with FASD participated in telephone interviews. Participants provided responses to the following two questions: “What do caregivers need to help young adults live as independently as possible?” and “What services would help young adults live as independently as …

This study focused on two of the modules, the ‘Four Tools for Conflict Resolution” and “Reactions to Grief and Loss”.

The results suggest …


Resiliency And Well-Being: Trajectories Of Change Over Time, Matthew Mclarnon Mar 2016

Resiliency And Well-Being: Trajectories Of Change Over Time, Matthew Mclarnon

Electronic Thesis and Dissertation Repository

Resiliency is often considered an attribute that can assist an individual in overcoming adversity. The predominant theme in the literature is that resiliency is positively related to achieving positive outcomes after a challenging experience. For example, stemming from Luthans and colleagues’ work on Psychological Capital (Luthans, Youssef, & Avolio, 2007), resiliency has been positively linked to psychological well-being, job satisfaction, and job performance. However, scant research is available on the processes behind resiliency and the mechanisms that promote well-being in the face of adversity. Therefore, the two studies comprising this dissertation aimed to address focal research questions around a) why …

Factors Associated With Disclosure Of Domestic Violence At The Workplace, Laura Olszowy

Electronic Thesis and Dissertation Repository

Workplaces have been increasingly recognized as an important venue for supporting and building safety for domestic violence victims. It is important to understand factors that are associated with disclosure of domestic violence at the workplace. This study utilized data from a pan-Canadian online survey on domestic violence and the workplace as the basis for an analysis of sociodemographic variables and situational variables that may be associated with the likelihood that a victim discloses domestic violence at their workplace. Results revealed that over 40% of victims disclosed in the workplace, with varying disclosure rates according to sociodemographic characteristics and the experience …


An Evaluation Of The Determinants Of Job Satisfaction In Canadian Family Physicians, Jana L. Malhotra Feb 2016

An Evaluation Of The Determinants Of Job Satisfaction In Canadian Family Physicians, Jana L. Malhotra

Electronic Thesis and Dissertation Repository

Physicians as a group appear to be satisfied with their work. However, there are some gaps in our current understanding of the determinants that impact the job satisfaction of Canadian family physicians. This thesis examined determinants of family physician job satisfaction using in-depth interviews with family physicians to achieve a broad perspective on their job satisfaction. This was complemented by a multivariate analysis that examined the professional and work-life balance satisfaction of physicians across this country. The findings from this research confirm the significance of a number of factors to the professional and work-life balance satisfaction of family physicians. Novel …


Teachers’ Help-Seeking Perceptions And Workplace Psychological Safety, Sheila M. Linseman Feb 2016

Teachers’ Help-Seeking Perceptions And Workplace Psychological Safety, Sheila M. Linseman

Electronic Thesis and Dissertation Repository

This objective of this study was to investigate teacher mental health, attitudes toward psychological help-seeking, and perceptions of psychological safety within schools. Findings from this study of 600 Canadian educational professionals revealed a higher frequency and severity of distress than in the general population, warranting intervention. Attitudes toward psychological help-seeking were generally positive, though less favorable than comparable published studies. Overall, participants rated their workplaces as “somewhat” psychologically safe. However, there were low ratings of work-life balance and respectful treatment of mental illness by leadership. Implications and recommendations of these findings were discussed.


Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus Dec 2015

Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus

Electronic Thesis and Dissertation Repository

Cigarette smoking is a leading agent for premature morbidity and mortality among the global community. Most individuals surrender to tobacco use disorder due to the inability to cope with cravings and withdrawal symptoms. Exercise appears to provide acute relief. Currently, it is unclear how exercise attenuates these reductions. Furthermore, the available evidence has focused on acute outcomes besides smoking behaviour and is limited to simulated quit attempts. Three experimental studies were designed to address these outstanding issues. Not surprisingly, a bout of moderate intensity exercise was found in study 1 (chapter 2) to reduce cravings associated with a temporary period …


Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan Dec 2015

Mathematical Modeling Of Stress Management Via Decisional Control, Matthew J. Shanahan

Electronic Thesis and Dissertation Repository

Engaging the environment through reason, humankind evaluates information, compares it to a standard of desirability, and selects the best option available. Stress is theorized to arise from the perception of survival-related demands on an organism. Cognitive efforts are no mere intellectual exercise when ontologically backed by survival-relevant reward or punishment. This dissertation examines the stressful impact, and countervailing peaceful impact, of environmental demands on cognitive efforts and of successful cognitive efforts on a person’s day-to-day environment, through mathematical modeling of ‘decisional control’. A modeling approach to clinical considerations is introduced in the first paper, “Clinical Mathematical Psychology”. A general exposition …


The Use Of Exercise Self-Talk By Female Adolescents, Sadie Puddister Dec 2015

The Use Of Exercise Self-Talk By Female Adolescents, Sadie Puddister

Electronic Thesis and Dissertation Repository

Already below recommended levels, physical activity participation in female youth is known to decline throughout adolescence. Self-talk, a form of self-regulation has been demonstrated to influence behaviour in both sport and exercise settings. The purpose of the present research was to explore the exercise related self-talk of teen girls (aged 14-18) with the intent of uncovering reoccurring themes and attributes in the self-talk of both low frequency exercisers (LFEs) and high frequency exercisers (HFEs). Participants were teen girls (N=28, Mage=15.56, SDage=1.47) recruited from A. B. Lucas Secondary School in London, Ontario. Physical activity …


Social Networking Sites And Personnel Selection: An Initial Validity Assessment, Travis J. Schneider Dec 2015

Social Networking Sites And Personnel Selection: An Initial Validity Assessment, Travis J. Schneider

Electronic Thesis and Dissertation Repository

The purpose of this dissertation was to add to the literature on the use of social networking sites (SNSs) for personnel selection. The first goal was to evaluate whether SNSs have the potential to be used as a valid source of information for selection. Specific SNS Indicator scales were created to test whether they have better validity evidence than the more traditionally-used Global SNS Rating. In a study of 141 undergraduate students at a large Canadian university, the Specific SNS Indicators demonstrated fairly weak evidence of interrater reliability, but some evidence of structural validity, and construct validity (convergent and discriminant). …


Exploring And Training Spatial Reasoning Via Eye Movements: Implications On Performance, Victoria A. Roach Dec 2015

Exploring And Training Spatial Reasoning Via Eye Movements: Implications On Performance, Victoria A. Roach

Electronic Thesis and Dissertation Repository

This dissertation sought to determine if eye movements could serve as an indicator of success in spatial reasoning, and if eye movements associated with successful completion could be applied to strategically improve spatial reasoning.

Using the line images of Shepard and Metzler, an electronic test of mental rotations ability (EMRT) was designed. Two versions of the test were created, allowing for both a timed (6 seconds per question) and untimed testing environment. Four experiments were designed and completed to relate mental rotation ability (MRA) scores from the EMRT, to patterns in chrononumeric and visual salience data. In each experiment, participants …


An Examination Of Daily Humour Styles And Relationship Satisfaction In Dating Couples, Sara Caird Nov 2015

An Examination Of Daily Humour Styles And Relationship Satisfaction In Dating Couples, Sara Caird

Electronic Thesis and Dissertation Repository

Humour can be both beneficial and harmful to romantic relationships. Research indicates that affiliative humour is associated with higher levels of relationship satisfaction, whereas aggressive humour is associated with lower levels of relationship satisfaction. However, past research is limited by its reliance on cross-sectional designs and general measures of humour use. Furthermore, little research has examined potential mediators that may account for the observed relationships between humour styles and relationship satisfaction. The current daily diary studies were the among the first to examine daily within-person associations between humour styles (specifically in the context of romantic relationship), relationship satisfaction, and positive …


Striving For Teaching Success: Enhancing Emotional Intelligence In Pre-Service Teachers, Ashley K. Vesely-Maillefer Oct 2015

Striving For Teaching Success: Enhancing Emotional Intelligence In Pre-Service Teachers, Ashley K. Vesely-Maillefer

Electronic Thesis and Dissertation Repository

Research has confirmed job dissatisfaction, and high levels of occupational stress and burnout resulting from the emotional demands of teaching. This dissertation focuses on a potential solution to support teachers’ psychological wellbeing in their paramount role to society: training in emotional intelligence. Recent research has demonstrated not only the positive role of emotional intelligence (EI) in enhancing stress management, coping skills, psychological wellbeing, and resilience, but that EI can be developed through EI training. Empirical evidence has recently shown support for EI training specifically within the teaching population. However, there remains a dearth of applicable empirically-based training programs aimed at …


Effects Of Motion Pattern Characteristics On The Perception Of Visual Acceleration, Alexandra S. Mueller Sep 2015

Effects Of Motion Pattern Characteristics On The Perception Of Visual Acceleration, Alexandra S. Mueller

Electronic Thesis and Dissertation Repository

The ability to perceive visual motion is one that we use every day to perform goal-directed activities, such as intercepting or avoiding objects. As objects and observers rarely move at constant velocities, it is important to be able to detect changes in velocity. However, little attention has been paid to how we perceive visual acceleration in the literature. This thesis explored the influence of real world-relevant motion pattern characteristics on visual acceleration perception. Observers rarely see object motion with an unlimited field of view, and therefore we first examined how physically constraining the horizontal distance over which a stimulus can …


Factors Influencing Continuity Of Attachment Quality In Early Childhood, Ya F. Xue Sep 2015

Factors Influencing Continuity Of Attachment Quality In Early Childhood, Ya F. Xue

Electronic Thesis and Dissertation Repository

Although the study of attachment continuity has flourished over the last several decades, gaps remain in the literature. These include a dearth of studies that have examined: 1) how children differ in their patterns of continuity in attachment quality; 2) factors that underlie these patterns; and 3) the roles that infant characteristics, such as children’s levels of susceptibility to parenting influences, have in shaping attachment stability. Correspondingly, this dissertation aimed to identify children’s patterns of continuity in attachment quality across early childhood, and to elucidate the processes that influence the development of these different patterns. Using Latent Class Analysis (LCA), …

Neural And Behavioural Responses To Rewards And Losses In Early Development: A Functional Magnetic Resonance Imaging Study, Niki Hosseini-Kamkar Sep 2015

Neural And Behavioural Responses To Rewards And Losses In Early Development: A Functional Magnetic Resonance Imaging Study, Niki Hosseini-Kamkar

Electronic Thesis and Dissertation Repository

Functional magnetic resonance imaging (fMRI) was used to investigate the neural and behavioural correlates of learning from rewards and losses in children. Greater blood-oxygen-level dependent (BOLD) responses in the ventral striatum (VS) and the ventromedial prefrontal cortex (VMPFC) were found when participants received rewards compared to when they missed out on an opportunity to receive rewards. In contrast, greater BOLD responses in the anterior insula (AI) and the anterior cingulate cortex (ACC) were found when participants received losses compared to when they avoided losing. The BOLD response to rewards in the VS and VMPFC correlated positively with the tendency to …
