“Just Say Yes” - Sexual Consent and Boundary Setting On-and Offlinle
The present study examined the understanding and behaviours relating to sexual consent on, and offline among men who have sex with men (MSM) and heterosexual men internationally using a convergent parallel mixed-methods approach. Men of both sexual orientation groups presented challenges with negotiating sexual consent, and this was especially true if they scored higher on aggressive traits or had previously experienced childhood abuse or an unwanted penetrative sexual act in adulthood. However, from the results as a whole, MSM reported struggle more with regards to consent negotiation for a variety of reasons (e.g. sexual scripts, power dynamics, additional sexual settings, sex-role positioning). Limitations and future directions are discussed. Author Keywords: heterosexual men, men who have sex with men, sexual assault, sexual consent, technology
Youth Justice in Canada
Strategies to reduce youth crime have been extensively researched and custody is not found to be effective. In the past, custody was a frequently used sentence, and while under the YOA the number of youth in custody was four times higher than that of adults in Canada. The use of custody sentences in Ontario has decreased in recent years, however; it remains above the Canadian average. Currently, alternatives to custody are also being implemented. This study aimed to gather lived experiences of those with firsthand experience in the youth justice system (offenders and staff). These individuals have working knowledge of effective practices for reducing recidivism. Eighteen semi-structured interviews were conducted. Interviews were coded and analysed using Interpretive Phenomenological Analysis. A number of themes emerged, including various views on the benefits of custody, the importance of relationships, challenges of the job and the need for increased focus on prevention.

Women's Lived Experience of Risk in Pregnancy
Cardiovascular disease (CVD) prevention, treatment and outcomes in women remain largely inequitable globally. Unique sex-specific stages of life, including pregnancy conditions, and their influence on cardiac risk is a growing area of research (Norris et al., 2020). For example, preeclampsia is strongly associated with CVD risk. This connection has led to prevention interventions such as postpartum risk clinics. Research to date on pregnancy and chronic disease is rooted in the medical paradigm of risk and lacks women’s lived experience. The present study qualitatively explored illness and risk perceptions of women with risky pregnancy conditions. Some participants felt self-blame for their conditions. Consequences and severity were focused on “baby first”, while maternal risk was viewed in the distant future. Aspects of the pregnancy experience, including prompt access to mental health support, was viewed as a “blessing in disguise”. Risks, such as lack of agency, and benefits of healthcare risk communication and intervention and implications for practice were also explored.

Why not give up? A study on the role of resourcefulness in goal pursuit
Past research suggests that taking a process oriented approach, setting clear and concrete goals, and using both conscious planning and proactive coping are the best methods to be successful with goal pursuit. Also the literature has found that individuals scoring higher in general resourcefulness tend to be more successful at achieving goals than their less resourceful counterparts. My thesis looked at these goal pursuit behaviours under the lens of resourcefulness using a mixed methods approach. After completing Rosenbaum’s self-control scale (1980) assessing general resourcefulness, participants took part in a semi-structured interview asking them about a recent goal they had set and how they dealt with interfering obstacles. The hope was hearing differences about how highly and less resourceful people discuss their goals and setbacks would give a deeper understanding about the characteristics of success. The themes emerging from the interviews were: blame and excuses versus understanding and growth, internal versus external factors, living in the moment versus conscious planning and magical versus realistic thinking. In contrast to low-scoring participants, highly resourceful individuals grew from their setbacks, were internally driven, consciously planned, and thought realistically about their goals. Less resourceful individual, on the other hand blamed outside factors and made excuses, were only motivated externally, didn’t plan out their goals and believed their goals would just magically materialize over time. My discussion focuses on the ability to train lower resourceful individuals over longer interventions, and the applications of understanding and using resourcefulness as a lens in future studies.

What Nature is Best?
Connecting with nature benefits human and environmental health, however it is unclear whether certain types of nature influence people differently. Research has primarily focused on green spaces (vegetation-rich areas), but recent cross-sectional studies suggest that green spaces with blue space (natural water elements) may have additional well-being benefits. A quasi-experimental design compared the effects of green spaces with or without water on mood and environmental concern. Students (N = 193) were randomly assigned to walk along campus green (drumlin) or blue (river) spaces. Both walks improved students’ mood, especially for those who had a stronger preference for the area. Students in both conditions reported more sustainable behaviours when followed up one week and one month later, but decreased in nature contact and well-being. These findings highlight the challenges of promoting regular nature contact as a mood regulation strategy. Implications and future directions are discussed. Author Keywords: blue space, green space, nature connectedness, well-being
WOMEN IN HORROR
The objective of this dissertation is to measure the influence of the contemporary influx of women’s involvement in the horror genre in three dimensional capacities: female representation in horror films, female representation as active, participatory spectators and female representation in the industrial production of horror. Through the combined approach of theoretical and empirical analysis, this dissertation examines the social conditions that facilitated women’s infiltration of the horror genre. Beginning with psychoanalytic theories of spectatorship, it is demonstrated that female filmmakers have challenged horror’s traditional images of victimized women through the development new forms of feminine representation in contemporary horror films. Using data collected from a sample of 52 self-identified female horror fans, it is revealed that the purported invisibility of female horror spectators is a consequence of their alternative modes of consumption. Through interviews conducted with four female producers and an examination of their cultural productions, I illustrate that women have reconstituted the horror genre as a space for inclusivity, political activism and feminist empowerment. Cohesively, these findings reveal the contemporary feminist reclamation of horror to be a form of resistance intended to challenge the patriarchal structures that facilitated women’s historical exclusion from the horror genre.

Vulnerability and resilience
The Minority Stress Model proposes that LGBTQ+ people experience stressors unique to their identity that negatively impact their mental well-being. The model also outlines that, in the case of the LGBTQ+ community, two minority coping resources - social support and connection to the LGBTQ+ community – may act as potential minority stress buffers; however, research has been unable to determine if these are effective buffers. The current study used multiple regression and multilevel modelling to test the processes of the Minority Stress Model among 451 LGBTQ+ people over 25 timepoints during the COVID-19 pandemic. Although minority stressors and coping resources were associated with psychological distress in the expected directions, an interesting interaction between the two measures of minority stress was revealed and neither minority coping resource was found to buffer the association between minority stress and distress. In conclusion, the present study found partial support for the Minority Stress Model using longitudinal data but highlights the complex nature of these processes and how they are conceptualised in research. Author Keywords: identity concealment, LGBTQ+ community, mental health, minority coping, minority stress model, social support
Using a real-world chopping task to study motor learning and memory
Typically task interference is studied using reaching adaptation tasks (visuomotor rotation and/or force-field learning). Participants in these experiments are already experts at the base task (point-to-point, planar reaching) and their ability to adapt reaching to the imposed perturbation is studied. The pattern of data induced by the perturbation is used to make inferences about the nature and neural correlates of our learning and memory for reaching perturbations, specifically, and motor performance in general. We wanted to see if it is possible to demonstrate this same interference pattern using a novel vegetable-chopping task, where we can easily recreate natural performance settings using a task for which we can easily identify non-experts. Participants performed a chopping task in which they are asked to chop a sweet potato into 5 mm-wide slices, matching the beat of a metronome (120 bpm). Following this initial learning, participants were exposed to an interference condition. Participants then performed trials of the original task again. Interference was inferred if the second performance of the original task was impaired, compared to initial performance. Experiment 1 involved novice choppers, and either the force or frequency of chops was manipulated. Only the altered frequency task produced interference effects. In Experiment 2, competent and expert choppers had to manage either a faster or slower frequency. We found evidence for interference in competents, but not experts. These results support the idea that the vulnerability to interference of motor memory changes with practice, and so any inferences made about memory structure must take into account not only expert performance, but every level of skill. Author Keywords: expertise, interference, motor learning, reaching adaptation
Use Of Rapid Amygdala Kindling With Corticosterone Supplementation As A Model Of Epilepsy-Depression Comorbidity
Temporal lobe epilepsy increases risk for developing major depression, and conversely, depression increases risk for development of epilepsy. The mechanisms responsible for the widely observed bi-directional relationship between epilepsy and depression are currently poorly understood. One reason why our understanding of shared etiology has had little improvement is due to the lack of availability of a reliable animal model for inducing depression in epileptic animals. The development of a reliable model of epilepsy-depression comorbidity would greatly improve the ability to mechanistically evaluate shared pathophysiology between the conditions. Recently there has been evidence that rapid kindling of the basolateral amygdala can evoke a behavioural phenotype that is comparable to the symptoms of anxiety and depression observed in depressed epileptic patients. However, this work has yet to be replicated, leaving question as to whether or not the behavioural phenotype can be reliably evoked. In the following series of experiments we assessed rapid amygdala kindling as a potential model of epilepsy-depression comorbidity and sought to improve the model with inclusion of the glucocorticoid corticosterone. Our findings may improve our understanding of the unique relationships between epilepsy and depression.

Unbridled Potential
Recently, equine assisted learning (EAL) has emerged as a novel approach to building resiliency competencies in at-risk youth. This mixed-methods study presents evaluation results for an 8-week community-based EAL program with 83 young women (age 13-18 years) with a history of interpersonal trauma. Analyses examined changes in self-reported mental health symptoms (posttraumatic, depression) and resiliency factors (sense of mastery, sense of relatedness, emotion regulation) from pre- to post-test and at 1-month and 6-month follow-ups. Changes in outcomes were also correlated with intervention processes (attendance, session ratings) to see if program experiences were associated with differential outcomes. Results showed that EAL has potential in improving resiliency outcomes, at least for those participants who derived greater satisfaction and value from the sessions. Many improvements were sustained over the long term. Participants’ qualitative feedback provided insight into their subjective experiences and highlighted the unique role that horses played in the EAL process.

Tool-use and near-tool effects
After active tool-use visual stimuli near a tool are processed more quickly and accurately than those farther away from a tool. Can these near-tool effects be modulated by training demands? To investigate this we asked the participants to complete a tool training task followed by a cross-modal interference task. During the training task the participants performed quick and accurate pointing movements to reach a strict or moderate criterion. The results indicated that the strict group made faster movements than the moderate group. During the cross-modal interference task visual distractors were presented along handheld tools in conjunction with vibrotactile stimuli on the hand. No significant compatibility effects were found for visual distractors near the hand or tool tip, and no consistent group differences were found. Our findings demonstrate the importance of using a novel tool during training, and that virtual stimuli may not be effective to elicit near-tool effects. Author Keywords: bimodal neurons, cross-modal interference, near-tool effects, tool training, training demands
To Sext or Not to Sext
The risks and benefits of sexting within an intimate relationship were explored. The present study focused on sexual gratification, relationship benefits, and sexual communication as benefits and risky sexual behaviour, unethical forwarding, and infidelity as risks. A cross-sectional online survey of both undergraduate students and a community sample was used. Results indicated that sexual gratification, relationship benefits (sexual and relationship satisfaction, relationship quality, and commitment), and sexual communication are related to sexting. It appears that risky sexual behaviour is not associated with sexting, instead those who sext frequently engage in more safer sex behaviours than those who sext infrequently. Unethical forwarding does not appear to happen very often in the context of intimate relationships. Lastly, the current research indicates that some participants are sexting secondary partners, and many consider sexting secondary partners infidelity. These results show that there are both risks and benefits of sexting, which can be used to develop sext education and therapeutic programs. Author Keywords: infidelity, relationship benefits, Sexting, sexual behaviour, sexual communication, sexual gratification
