Abstract: <p>Pain conditions occur at an increasing rate alongside people with temporal lobe epilepsy (TLE) and can include chronic headaches, migraines, and neuropathic pain. In order to begin to understand the concurrence, this experiment aimed to investigate the effect of long-term amygdala kindling, a model of TLE, on the affective and nociceptive components of pain in rats. Formalin-induced… more Year: 2025, 2025

Abstract: <p>It is well known that pain can heighten sensitivity to stimuli that signal threat in most species. In rodents, exposure to predator odor, such as 2,5-dihydro-2,4,5-trimethylthiazoline (TMT), induces anxiety and alters pain sensitivity. This study explored the effect of predator odor stress on mechanical pain sensitivity in a rat model of acute inflammatory pain induced by suboptimal… more Year: 2025, 2025

Abstract: <p>Metaphors are a ubiquitous component of communication, which are either conventional (familiar) or novel phrases. Metaphors are useful for discussing abstract concepts such as emotions that can be difficult to discuss literally, and as such benefit social relationships (Nippold et al., 2017). Research on contributors to novel metaphor production is limited and previous methodologies have… more Year: 2025, 2025

Abstract: <p>Prevailing rates of sexual violence have necessitated research on sexual consentcommunication to remedy these issues. Research has found that individuals possess sophisticated
knowledge of consent, and that discrepancies between people's attitudes and behaviours are
resulting in sexual violence and compliance behaviours. The BDSM community–with its greater
diversity and effective… more Year: 2025, 2025

Abstract: <p>An athlete's psychological response to a sports-related concussion may influence thesuccess of recovery and return to play. This exploratory study explored how athletes
psychologically respond to concussion, using Acceptance and Commitment Therapy to
examine the role of psychological flexibility in recovery and return to play. Thirty
athletes who experienced a concussion in the past… more Year: 2025, 2025

Abstract: <p>This thesis aimed to explore students' perspectives on university exams in two studies. Using a phenomenological approach, Study 1 recruited 10 senior undergraduate students to participate in semi-structured interviews. A thematic analysis revealed key themes related to exam purpose, effectiveness, fairness, and emotional responses. These insights informed the development of a… more Year: 2025, 2025

Abstract: <p>Office workers consistently report greater productivity in the workplace when standing compared to sitting (Chambers et al., 2019; MacEwan et al., 2015; Mantzari et al., 2018). In contrast, laboratory studies report inconsistent evidence that posture (sitting vs. standing) affects cognitive performance, usually operationalized as selective attention (Caron et al., 2020; 2022; Rosenbaum… more Year: 2025, 2025

Abstract: <p>Stress can significantly affect neurobiological processes crucial for learning and memory. While repeated stress enhances fear memory, it impairs memory retrieval. In most studies, however, stress exposure typically preceded fear and extinction learning. Thus, the impact of previously acquired memories formed before exposure to stress is not well understood. The goal of this thesis is to… more Year: 2025, 2025

Abstract: <p>This study investigates associations between self-other differentiation (the ability to distinguish and coordinate the self and other perspective during social problem-solving) and specific ego functions (reality testing, judgement, sense of reality, object relations, and synthetic-integrative function) from a cognitive perspective in two groups of adolescents aged 12 to 18 years. One… more Year: 2025, 2025

Abstract: <p>In today's digital era, smartphone use is having a profound effect on family life. There is growing concern about parental phubbing, which occurs when parents ignore their children in favour of using their phones. This study examined how parental phubbing was associated with children's problematic media use (PMU), and problem behaviours (internalizing, externalizing,attention)… more Year: 2025, 2025

Contextual fear conditioning (CFC) studies in rats demonstrate that distributing conditioning over multiple sessions makes a memory less vulnerable to HPC damage, and it has been suggested this occurs through incremental strengthening of the memory outside the HPC via separate… more Year: 2025, 2025

Abstract: <p>Risk-taking (e.g., dangerous driving, substance use) rises during adolescence and can result in both adaptive consequences (e.g., social acceptance) and maladaptive consequences (e.g., alcohol poisoning, premature death). Adolescents also experience an increase in self-conscious emotions, including shame. Shame-prone adolescents may engage in risk-taking to cope with negative self-… more
