Epistemic Emotions and the Number of Sources Explored
Several theories postulate that epistemic emotions, such as curiosity and surprise, motivate information-seeking. In these theories, information-seeking is treated as a unitary, singular construct, with the motivation ... -
Beta-Band EEG Activity and False-Belief Reasoning in Adults
The ability to reason about other’s beliefs, and in particular their false beliefs, is a fundamental part of having a theory of mind (ToM) – an understanding of the role that mental states (i.e., beliefs, desires, and ... -
Characterizing the long-lasting impact of stress in mid-adolescence in the rat.
Exposure to stressors in adolescence, in both humans and rodents, leads to long-lasting alterations in their behaviour and corresponding neuroanatomical structures. The experiments presented herein were designed to further ... -
Maternal Attitudes and Infant/Child Temperament: Questionnaire Assessment and Applied Intervention
The importance of the parent-child relationship is reflected in a great deal of research, theory, and public health programs. The complexity of these relationships creates methodological challenges for researchers and ... -
An Exploratory Study of Novel Measures to Capture Situational Expressive Suppression
Expressive suppression is widely believed to be a maladaptive emotion regulation strategy due to its association with poor social functioning. Nonetheless, controlling when and how to express emotions is also the hallmark ... -
Exploring The Role of Referential Context in Young Children's Cross-Situational Word Learning
A fundamental question in early language acquisition concerns how young children learn new words despite often hearing them in visually complex and noisy environments. One potential mechanism that has emerged in recent ... -
Exploring Victimization Experiences of Sexual Minority Adolescents and their Associations with Mental Health and Help-Seeking Behaviours: A Minority Stress Perspective
Victimization in adolescence is associated with a variety of negative psychopathological and social outcomes, and is predictive of recurrent victimization over the lifespan (Wolke & Lereya, 2015; Feiring & Furman, 2000). ... -
The role of avoidance and stress in understanding emotional dysfunction in adults and adolescents with a fixed emotion mindset
Emotion mindsets refer to global beliefs about the controllability of one’s emotions. Individuals with fixed emotion mindsets view their emotions as uncontrollable and believe that no effort or strategy on their part can ... -
Behavioural Manifestations and Relational Correlates of Individual Differences in Theory of Mind
Although it is impossible to know the contents of others’ minds with absolute certainty, we can (and do) make probabilistic guesses about what others are thinking or feeling. When these judgments are made based on observable ... -
Neural Correlates of Sexual Response: An ERP Investigation of Responses to De-Contextualized Sexual Cues
Sexual response relies on the perceptual and cognitive processing of sexual stimuli. With its high temporal resolution, the event-related potential (ERP) technique offers an ideal tool for studying early processes involved ... -
Exploring the Role of Oxytocin in Rodent Defensive Behaviours
Although evidence implicates oxytocin (OT) in anxiety regulation, little is known about where this occurs in the brain or if this system is altered by social affiliation. I hypothesized that infusions of OT into the lateral ... -
Investigating the Role of Dopamine in Opioid Reward in Chronic Neuropathic Pain
Background: Neuropathic (NP) pain is commonly treated with opioids, such as morphine, despite acknowledgement that these drugs produce long-term complications including tolerance and addiction. Opioids have two effects on ... -
Cognitive Performance in Geriatric Depression: Examining the Sensitivity of Clinical Neuropsychological and Experimental Working Memory Tasks
Background: Traditional neuropsychological measurement tools have identified a proportion of individuals with late life Major Depressive Disorder (MDD) who experience modest to moderate cognitive impairments. These cognitive ... -
A Subjective Measure of Attitude Extremity: Validation and Extension
Attitudes are individuals’ enduring global evaluations of objects, concepts, or ideas, which may vary in both valence and extremity. There are many important determinants of attitudes and attitude strength, with research ... -
Cognitive Training in Major Depressive Disorder: Perceptions of Cognitive Malleability, Importance of Autonomy, and Efficacy of a Brief Psychoeducational Intervention
Cognitive difficulties constitute a diagnostic criterion of major depressive disorder (MDD) and are associated with functional impairments and barriers to recovery in this condition. Cognitive Remediation (CR) is a ... -
Dysphoria as a Moderator of Online Self-Presentation Via Image Selection
The current research consists of two studies to examine the relationship between dysphoria (i.e., subclinical depression or chronic negative mood) and visual self-presentation online. In Study 1, I compared dysphoric and ... -
COMPUTATIONAL IMPLEMENTATION OF THE INCENTIVE -SENSITIZATION THEORY OF ADDICTION
In the mid-1990s, the disease model of addiction replaced the moral model, emphasizing the underlying neurological mechanism of addiction. In accord with this view, the Incentive-Sensitization theory provides an account ... -
Investigating the Role of LPS-Induced Neuroinflammation as a Potential Mechanism of Anhedonia
Anhedonia, a deficit in reward processing, is a characteristic of many neuropsychiatric conditions including eating disorders, schizophrenia, substance use disorder and major depressive disorder (MDD) (American Psychiatric ... -
Possible Mechanisms of Order Matching Effects in Attitude Persuasion
The order persuasion matching effect occurs when the sequencing of information within a persuasive message matches that of the information used to generate said attitude. This matching effect generates stronger attitude ... -
Neural Transition Metric in fMRI: Categorization and Application
Recent advances in technology allow us to examine brain network dynamics in fMRI on a large-scale. Our lab has recently developed a data-driven method, the neural transition metric (Tseng & Poppenk, 2020), which allows us ...
