The Relations Between Newcomer Integration Processes And Youth Athletes’ Perceptions Of The Group Environment In Competitive Ice Hockey, Jeffrey J. Chamberlain
The Relations Between Newcomer Integration Processes And Youth Athletes’ Perceptions Of The Group Environment In Competitive Ice Hockey, Jeffrey J. Chamberlain
Electronic Thesis and Dissertation Repository
Abstract
The ways in which new members are integrated into a particular group environment—also known as organizational socialization processes—have been shown to be a powerful predictor of newcomer adjustment in the workplace. Yet, there is a scarcity of research on how sport teams manage the integration of new team members, and the consequences of different tactics. The current research uses the recently developed Sport Team Socialization Tactics Questionnaire (STSTQ) to evaluate how socialization processes are systematically related to youth athletes’ perceptions of their group environment. Across two time points, 202 competitive adolescent ice hockey players (Mage = 14.47, …
Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford
Using Meditation To Improve Measures Of Attention In Older Adults, Sabrina Ford
Electronic Thesis and Dissertation Repository
Age-related cognitive decline greatly impacts quality of life for older adults. Previous research has indicated that meditation may act as a neuroprotective factor to prevent age-related cognitive decline. This thesis sought to replicate previous findings and investigate if a four-week meditation intervention would improve sustained attention. Participants 60 years and older (n=27, 17 female) were recruited and assigned to a focused-attention (FA) meditation or relaxation group which met for four weeks, three times a week. Resting-state EEG was used to collect individual alpha peak frequency (iAPF) and frontal alpha asymmetry (FAA). The Sustained Attention to Response Task (SART) was also …
Pattern Separation In The Ventral Visual Stream, Kayla Ferko
Pattern Separation In The Ventral Visual Stream, Kayla Ferko
Electronic Thesis and Dissertation Repository
Pattern separation is a neural computation thought to underlie our ability to form distinct memories of similar events. It involves transforming overlapping inputs into less overlapping outputs. In the ventral visual stream (VVS) there is considerable evidence for hierarchical transformation from feature-based visual representations to conjunctive whole-object representations, with the latter allowing for distinct coding even when objects have significant feature overlap. In the current study, we asked whether this transformation can be understood as pattern separation, and whether pattern separation can be observed even outside the context of classic recognition-memory tasks. To investigate pattern separation in the VVS, we …
Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
Electronic Thesis and Dissertation Repository
For decades researchers have used 2D stimuli under the assumption that they accurately represent real objects. This assumption has been challenged by recent vision and neuroeconomics research which has found that 2D images can evoke different neural and behavioural responses than real objects. The current study continues this line of research in the field of affective cognitive neuroscience; a field where small effect sizes are common and rapid habituation to affective stimuli used in the lab often occurs. The present study uses realistic 2D and 3D emotional images to determine the impact of visual dimension on affective responding. Subjective ratings …
Resedent Study- Reducing Sedentary Behaviour May Slow Cognitive Decline In Older Adults With Mild Cognitive Impairment: A Pilot Study, Kirsten B. Dillon
Resedent Study- Reducing Sedentary Behaviour May Slow Cognitive Decline In Older Adults With Mild Cognitive Impairment: A Pilot Study, Kirsten B. Dillon
Electronic Thesis and Dissertation Repository
Physical activity (PA) has been shown to slow down dementia. Unfortunately, older adults spend most of their day in sedentary behaviours (SB). Breaking up prolonged bouts of sitting with intermittent bouts of light intensity PA may reduce glycemic variability in the brain; potentially mitigating cognitive decline. This study investigated how interrupting SB with 10 min bouts of light intensity PA 3x a day would affect mild to moderate cognitive impairment progression (primary outcome) in older adults residing in an assisted living facility. Participants (n=25) were assigned in clusters into a two arm 10-week single site pilot randomized controlled trial. Secondary …
Investigating How Neural Entrainment Relates To Beat Perception By Disentangling The Stimulus-Driven Response, Aaron Wc Gibbings
Investigating How Neural Entrainment Relates To Beat Perception By Disentangling The Stimulus-Driven Response, Aaron Wc Gibbings
Electronic Thesis and Dissertation Repository
Beat perception – the ability to perceive a steady pulse in music – is nearly ubiquitous in humans, but the neural mechanisms underlying this ability are unknown. A growing number of electroencephalography (EEG) studies suggest that beat perception is related to neural entrainment, a phenomenon in which cyclic changes in the excitability of populations of neurons synchronize with a rhythmic stimulus. However, the relationship between acoustically-driven and entrainment-driven neural activity is unclear. This thesis presents EEG research that extends our understanding neural entrainment is related to beat perception by characterizing, equating, and finally removing the stimulus-driven response in the neural …
The Dissociable Impact Of Auditory Vs. Visual Emotional Cues On Visual Processing, Emma K. Stewart Bsc, Derek Gv Mitchell Phd
The Dissociable Impact Of Auditory Vs. Visual Emotional Cues On Visual Processing, Emma K. Stewart Bsc, Derek Gv Mitchell Phd
Western Research Forum
Background: Emotional information has privileged access to processing resources, which can cause it to have a distracting or facilitating effect on task performance for reasons that are poorly understood. The sensory modality through which it is presented may be one determining factor. Some findings suggest that auditory stimuli facilitate visual task performance while visual stimuli interfere with it, but there are conflicting findings.
Hypothesis: We hypothesize that emotional content of a different sensory modality from the task improves task-related performance via a general alerting and arousing effect for all stimuli, while emotional content of the same modality disrupts performance when …
The Effects Of Acute Aerobic Exercise And Caffeine On Working Memory And Caffeine Withdrawal, Anisa Morava
The Effects Of Acute Aerobic Exercise And Caffeine On Working Memory And Caffeine Withdrawal, Anisa Morava
Electronic Thesis and Dissertation Repository
Caffeine is one of the most widely used psychoactive substances worldwide. Although caffeine elicits cognitive benefits, there are concerns regarding caffeine’s effects on certain health domains. Acute, aerobic exercise has been shown to improve cognition. The effects of aerobic exercise in comparison to caffeine on working memory (WM) in non-caffeine and caffeine consumers remains unknown. Furthermore, the effects of aerobic exercise in reducing caffeine withdrawal symptoms has yet to be examined. In Phase I, twenty-nine non-caffeine and thirty caffeine consumers completed a WM assessment, followed by aerobic exercise and caffeine administration (counterbalanced). In Phase II, twenty-five caffeine consumers underwent a …
The Origins And Development Of Visual Categorization, Laura Cabral
The Origins And Development Of Visual Categorization, Laura Cabral
Electronic Thesis and Dissertation Repository
Forming categories is a core part of human cognition, allowing us to make quickly make inferences about our environment. This thesis investigated some of the major theoretical interpretations surrounding the neural basis of visual category development. In adults, there are category-selective regions (e.g. in ventral temporal cortex) and networks (which include regions outside traditional visual regions—e.g. the amygdala) that support visual categorization. While there has been extensive behavioural work investigating visual categorization in infants, the neural sequence of development remains poorly understood. Based on behavioral experiments, one view holds that infants are initially using subcortical structures to recognize faces. Indeed, …
Spontaneous Mimicry Of Emotional Facial Expressions As A Function Of Trait Sadism, Cathleen Fleury, Mary Ritchie, Derek Mitchell
Spontaneous Mimicry Of Emotional Facial Expressions As A Function Of Trait Sadism, Cathleen Fleury, Mary Ritchie, Derek Mitchell
Western Research Forum
Using electromyography (EMG), it has been shown that facial muscles imperceptibly mirror the facial expressions of others, a phenomenon referred to as spontaneous facial mimicry. Facial mimicry may be involved in empathy processing, and is impaired in several empathy deficit disorders. It was previously believed to follow the direct-matching principle, a theory postulating that spontaneous facial mimicry involves the observer mirroring their partner’s expression exactly. However, several recent studies have demonstrated that context and individual differences may be influencing factors of spontaneous facial mimicry. In the present study, we propose to investigate the relationship between facial mimicry and empathy through …
Cognition And The Brain Of Brood Parasitic Cowbirds., David F Sherry, Mélanie F Guigueno
Cognition And The Brain Of Brood Parasitic Cowbirds., David F Sherry, Mélanie F Guigueno
Psychology Publications
Cowbirds are brood parasites. Females lay their eggs in the nests of other species, which then incubate the cowbird eggs and raise the young cowbirds. Finding and returning to heterospecific nests presents cowbirds with several cognitive challenges. In some species, such as brown-headed cowbirds (Molothrus ater), females but not males search for and remember the locations of potential host nests. We describe recent research on sex differences in cognition and the hippocampus associated with this sex difference in search for host nests. Female brown-headed cowbirds perform better than males on some, but not all, tests of spatial memory and females …
Cardiodynamic Associations With Resilience In Undergraduate Students And The Effect Of A Mentorship Intervention, Rachel J. Knetsch
Cardiodynamic Associations With Resilience In Undergraduate Students And The Effect Of A Mentorship Intervention, Rachel J. Knetsch
Electronic Thesis and Dissertation Repository
The National College Health Assessment (NCHA) indicates that a majority of Canadian university students report feeling overwhelmed, stressed, and anxious during their undergraduate studies. Resilience refers to positive adaptation, or the ability to maintain or regain mental health, despite experiencing adversity (Herrman et al., 2011). While autonomic indices have been used to describe chronic physiological stress, the role of heart rate variability (HRV) as an index of resilience remains unclear. This research tested the hypotheses that (1) there is a relationship between HRV and resilience scoresand (2) a mentorship intervention will improve HRV and resilience outcomes. Fifty-seven first year students …
Characterizing The Cognitive And Emotional Effects Of Delta-9-Tetrahydrocannabinol In Distinct Hippocampal Sub-Regions, Dinat Khan
Electronic Thesis and Dissertation Repository
The objective of this study is to determine the potential differential effects of THC in the DH or VH sub-regions, as well as the upstream effects on PFC neuronal activity and oscillations. Rodents used for electrophysiology were infused with THC or vehicle in the DH or VH regions, combined with PFC recordings. Additionally, a battery of behavioural paradigms was performed. Deficits in short-term memory when THC was infused into both regions was observed, however working memory was impaired with VH infusions only. This could be due to THC-induced dysregulation in the PFC, as beta oscillations were significantly decreased selectively in …
Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs
Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs
Electronic Thesis and Dissertation Repository
Exercise improves anxiety and depression, both of which are associated with impaired autonomic regulation of heart rate (HR). In turn, HR variability (HRV) is a reliable physiological indicator of external stressors. The following research tested the hypothesis that HRV is indicative of chronic resilience towards mental stress in female varsity hockey players. Seventeen varsity hockey players (HOCK, age 21 ± 1.5) and fifteen healthy controls (CTRL, age 21 ± 2.2) at Western University participated three times throughout a 7-month season. Participants completed questionnaires (brief resilience scale, BRS; generalized anxiety scale, GAD-7; mental health inventory, MHI; visual analog scale, VAS; short …
Girls’ Internalizing Symptoms And White Matter Tracts In Cortico-Limbic Circuitry, Ola Mohamed Ali
Girls’ Internalizing Symptoms And White Matter Tracts In Cortico-Limbic Circuitry, Ola Mohamed Ali
Electronic Thesis and Dissertation Repository
Dysfunction in cortico-limbic circuitry is implicated in internalizing disorders, but less is known about whether structural abnormalities precede disorder, thus potentially marking risk. I therefore examined associations between white matter tract integrity in cortico-limbic circuitry at age 7, obtained using Diffusion Tensor Imaging, and concurrent and longitudinal patterns of internalizing symptoms, over a 5-year period, in 42 typically developing girls. Using Automated Fiber Quantification, diffusion properties were examined at multiple points along tract length (cf., an average diffusion measure of the entire tract). Concurrent internalizing symptoms were associated with reduced fractional anisotropy in segments of the cingulum bundle and uncinate …
Multisensory Integration And Autistic Traits Using Non-Sociolinguistic Information, Sébastien A. Lauzon, Samantha E. Schulz, Zack I. Cohen, Ryan A. Stevenson
Multisensory Integration And Autistic Traits Using Non-Sociolinguistic Information, Sébastien A. Lauzon, Samantha E. Schulz, Zack I. Cohen, Ryan A. Stevenson
Western Research Forum
Background: Sensory processing issues are one of the most common complaints in autism spectrum disorder (ASD). One area of sensory difficulties in ASD that has been the focus of intense research in recent years is multisensory integration (MSI), or the ability to bind auditory and visual information into a single, unified percept. While integration of social or linguistic information is consistently shown to be an area of difficulty in ASD, results are less clear with simple, non-sociolinguistic stimuli. This study aims to address this ambiguity by determining whether MSI of non-sociolinguistic sensory information is related to traits and symptomatology …
A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan
A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan
Electronic Thesis and Dissertation Repository
Attention Restoration Theory (ART) predicts that top-down processing during everyday activities can cause attentional fatigue and that bottom-up processing that occurs when people experience nature will be restorative (Kaplan, 1995). The present study examined this prediction by exposing participants to three different conditions using a repeated measures design: a control condition during which participants walked on a typical treadmill, a nature/restorative condition during which participants walked on the same treadmill, experiencing a simulated nature walk, and a perturbation condition that included the same simulated nature scene but also required top-down processing during the walk. The findings supported ART predictions. As …
The Neural Mechanisms Underlying The Perception And Production Of Learned Vocalizations In Songbirds, Shannon Katie Mischler
The Neural Mechanisms Underlying The Perception And Production Of Learned Vocalizations In Songbirds, Shannon Katie Mischler
Electronic Thesis and Dissertation Repository
Songbirds produce a wide array of vocalizations, including song, and learned and innate calls. Songs and calls can be functionally defined. Songs are typically used to attract potential mates and defend one’s territory, whereas calls are used for everything else, such as advertising the presence of a predator, or location of a food source, and maintaining contact with members of one’s flock. The purpose of this thesis was to better understand the neural mechanisms underlying call production and perception in two songbird species; the black-capped chickadee (Poecile atricapillus) and the zebra finch (Taeniopygia guttata). My objectives …
A Diffusion Tensor Imaging Study Of Motor Fibre Path Integrity And Overt Responsiveness In Disorders Of Consciousness, Clara A. Stafford
A Diffusion Tensor Imaging Study Of Motor Fibre Path Integrity And Overt Responsiveness In Disorders Of Consciousness, Clara A. Stafford
Electronic Thesis and Dissertation Repository
This study investigated the relationship between motor thalamo-cortico-cerebellar fibre path integrity and overt responsiveness in patients with disorders of consciousness (DOC). Additionally, we investigated the potential of imaging these motor tracts at ultra-high fields. Study I and II aimed to map the white matter connections of motor execution fibres in DOC patients. Our results showed significant reductions in motor fibre path integrity across DOC diagnostic categories. Study III and IV aimed to develop a 7T MRI Diffusion Tensor Imaging (DTI) sequence. We optimized this sequence to image motor fibre paths in DOC patients. We concluded that, in healthy controls, probabilistic …
An Investigation Of Propranolol As An Agent For The Experimental Manipulation Of Interoception., Jane Evguenia Kouptsova
An Investigation Of Propranolol As An Agent For The Experimental Manipulation Of Interoception., Jane Evguenia Kouptsova
Electronic Thesis and Dissertation Repository
Interoception has recently come under research focus as a potential influence on emotional and epistemic feelings. However, existing means to manipulate it experimentally have conceptual or logistical drawbacks. We investigated whether 20 mg of propranolol is a viable agent for experimentally manipulating interoception. Thirteen participants completed a double-blind, placebo-controlled crossover study, performing two heartbeat perception tasks, control tasks and measures of anxiety and alertness. All measures were obtained at the beginning and end of both sessions. Propranolol significantly decreased heart rate and systolic blood pressure. Heartbeat detection performance numerically decreased under propranolol, although this effect failed to reach statistical significance. …
The Influence Of Estrogen On Sex Differences In Chemotherapy-Induced Nausea And Vomiting (Cinv), Danna L. Zevy
The Influence Of Estrogen On Sex Differences In Chemotherapy-Induced Nausea And Vomiting (Cinv), Danna L. Zevy
Electronic Thesis and Dissertation Repository
Chemotherapy-induced nausea and vomiting (CINV) is one of the most distressing events that affects the quality of life of cancer patients. Evidence suggests that females are more susceptible to CINV than males, but the mechanism remains unknown. The current thesis examined whether higher levels of circulating estrogens in females contributes to this sex difference. CINV was analyzed in a pediatric oncology population, where it was revealed female patients demonstrate increased delayed CINV relative to male patients, in the post-pubertal age group. CINV was also studied by examining the influence of the estrous cycle on anticipatory nausea (AN) in rats. This …
Promoting Benefits Of Physical Activity Through Persuasive Communication, Priynka Patil
Promoting Benefits Of Physical Activity Through Persuasive Communication, Priynka Patil
Electronic Thesis and Dissertation Repository
Inactivity early in life can lead to inactively later in life, which can result in negative outcomes. The primary purpose was to determine if gain- or loss-framed messages about physical activity would change the attitudes, intentions, and behaviours of students in the contemplation or preparation stage of the Transtheoretical model. The secondary purpose was to determine if framing the message in terms of the physical health benefits, appearance/social benefits, or mental health benefits (benefit condition) would change attitude, intention and behaviour. Undergraduate female students (N=60) between the ages of 18 and 36 were recruited from the university. The results found …
Transcranial Magnetic Stimulation To Assess Motor System Excitability Fluctuations During Auditory Anticipation And Beat Perception, Johannes G.P Teselink
Transcranial Magnetic Stimulation To Assess Motor System Excitability Fluctuations During Auditory Anticipation And Beat Perception, Johannes G.P Teselink
Undergraduate Honors Theses
Humans tend to spontaneously move to the regular beat of musical rhythm. Beat perception is the tendency to sense and anticipate the regular time positions (beats) that movements synchronize with. The neural motor system plays an important role in beat perception, but the dynamics of excitability in the motor system associated with beat perception have not been characterized. This project investigated motor system excitability fluctuations using transcranial magnetic stimulation and electromyography during perception of beat-based and non-beat-based rhythms. We applied single-pulse TMS over the left primary motor cortex of healthy participants as they listened to three types of rhythms that …

Origins Of Thalamic And Cortical Projections To The Posterior Auditory Field In Congenitally Deaf Cats., Blake E Butler, Nicole Chabot, Andrej Kral, Stephen G Lomber
Origins Of Thalamic And Cortical Projections To The Posterior Auditory Field In Congenitally Deaf Cats., Blake E Butler, Nicole Chabot, Andrej Kral, Stephen G Lomber
Psychology Publications
Crossmodal plasticity takes place following sensory loss, such that areas that normally process the missing modality are reorganized to provide compensatory function in the remaining sensory systems. For example, congenitally deaf cats outperform normal hearing animals on localization of visual stimuli presented in the periphery, and this advantage has been shown to be mediated by the posterior auditory field (PAF). In order to determine the nature of the anatomical differences that underlie this phenomenon, we injected a retrograde tracer into PAF of congenitally deaf animals and quantified the thalamic and cortical projections to this field. The pattern of projections from …
Are There Place Cells In The Avian Hippocampus?, David F Sherry, Stephanie L Grella, Mélanie F Guigueno, David J White, Diano F Marrone
Are There Place Cells In The Avian Hippocampus?, David F Sherry, Stephanie L Grella, Mélanie F Guigueno, David J White, Diano F Marrone
Psychology Publications
Birds possess a hippocampus that serves many of the same spatial and mnemonic functions as the mammalian hippocampus but achieves these outcomes with a dramatically different neuroanatomical organization. The properties of spatially responsive neurons in birds and mammals are also different. Much of the contemporary interest in the role of the mammalian hippocampus in spatial representation dates to the discovery of place cells in the rat hippocampus. Since that time, cells that respond to head direction and cells that encode a grid-like representation of space have been described in the rat brain. Research with homing pigeons has discovered hippocampal cells, …
The Neural And Cognitive Basis Of Cumulative Lifetime Familiarity Assessment, Devin Duke
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 …

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 …
Neural And Behavioural Responses To Rewards And Losses In Early Development: A Functional Magnetic Resonance Imaging Study, Niki Hosseini-Kamkar
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 …
Contrasting Styles In Cognition And Behaviour In Bumblebees And Honeybees., David F Sherry, Caroline G Strang
Contrasting Styles In Cognition And Behaviour In Bumblebees And Honeybees., David F Sherry, Caroline G Strang
Psychology Publications
Bumblebees and honeybees have been the subjects of a great deal of recent research in animal cognition. Many of the major topics in cognition, including memory, attention, concept learning, numerosity, spatial cognition, timing, social learning, and metacognition have been examined in bumblebees, honeybees, or both. Although bumblebees and honeybees are very closely related, they also differ in important ways, including social organization, development, and foraging behaviour. We examine whether differences between bumblebees and honeybees in cognitive processes are related to differences in their natural history and behaviour. There are differences in some cognitive traits, such as serial reversal learning and …
