P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak
P300 Event-Related Potential Responses To Self-Relevant Stimuli, Jordan Razzak
Electronic Theses and Dissertations
Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically …
A Phenomenological Study Of School Psychologists: The Influence Of Implicit Bias On The Disproportionate Identification Rates Of African American Students Evaluated For Emotional Disturbance, Sonya Coe-Milo
Electronic Theses and Dissertations
As advocates, school psychologists remain ethically responsible and uniquely positioned to identify social injustices and promote nondiscriminatory practices in prekindergarten through grade 12 public education institutions. Implicit bias and its influence on African American students is one such practice. In public education, implicit bias contributes to discipline disproportionality, differentiated teacher support, pedagogical practices, and adult perceptions and expectations of appropriate and inappropriate behaviors. These factors directly correlate to the disproportionate identification rates of African American students for special education and related services. Therefore, this phenomenological qualitative study examined the personal, lived experiences and perceptions of school psychologists regarding implicit bias …
Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel
Formalizing The Faustian Bargain Within The Healthcare Domain: An End-Of-Life Approach., Rachel Appel
Electronic Theses and Dissertations
A Faustian Bargain refers to an individual making a “deal with the devil,” exchanging something moral or sacred for an unattainable earthly good. The Faustian Bargain has been used to describe a ubiquitous social dilemma inherent to human civilization: exchanging individual liberty for public goods (e.g., security) provided by societal leaders and governments (Ostrom, 1980). Research on Faustian Bargains often examines tradeoffs between outcome utility (i.e., value derived from the outcomes of a decision) and procedural utility (i.e., value derived from being involved in the decision process (e.g., Frey et al., 2004). Much of the research on Faustian Bargains has …
Exploring The Relationship Between Of Subjective And Objective Cognition Among Older Adults Living In Canada, Astrid Dawn Coleman
Exploring The Relationship Between Of Subjective And Objective Cognition Among Older Adults Living In Canada, Astrid Dawn Coleman
Electronic Theses and Dissertations
The older adult population in Canada is growing rapidly, increasing the prevalence and burden of conditions that impact these individuals, such as dementia. Given that early detection and intervention are strongly associated with better disease outcomes, understanding the progression from healthy aging to dementia is critical. Two factors contributing to disease progression are cognitive impairment on objective neuropsychological measures and subjective cognitive complaints. However, the association between individuals’ perceptions of their cognitive abilities and their performance on cognitive tests remains unclear. Therefore, the goal of this project was to gain insight into the relationship between subjective and objective cognitive functioning …
The Self-Reference Effect On Memory Among 4- To 6-Year-Olds: The Role Of Active Encoding And Cognitive Abilities, Alicia Nicole Bartlett
The Self-Reference Effect On Memory Among 4- To 6-Year-Olds: The Role Of Active Encoding And Cognitive Abilities, Alicia Nicole Bartlett
Electronic Theses and Dissertations
The self-reference effect (SRE) is the enhanced memory for information encoded with reference to oneself relative to information encoded with reference to another non-intimate person or the linguistic properties of a word (Rogers et al., 1977). This effect is measured with an encoding task and a surprise recall and/or recognition task. An important distinction among encoding tasks is whether they involve active or passive engagement with the to-be-remembered information. Tasks with active engagement require the participant to identify the relation between the referent and target object and then to perform a mental (e.g., evaluate desirability of objects) or physical (e.g., …
Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise
Investigating Visual Vigilance Following Chronic Behavioural Immune System Activation, Jessica Hurtubise
Electronic Theses and Dissertations
The behavioural immune system (BIS) is a coordinated set of cognitive, affective, and behavioural responses that minimize pathogen contact. Prior to the COVID-19 pandemic, the majority of research on the BIS was limited to situations of acute pathogen threat. These studies identified that personal predispositions and environmental stimuli interact and lead to cognitive changes, including perceptual enhancements and attentional biases, as well as sensations of disgust. The cognitive and affective changes that follow pathogen exposure motivate pathogen avoidance behaviours and reduce the risk of infection. The BIS is highly adaptive in the context of acute pathogen threat, but less is …
Oral Contraception And Cognition, Kathleen Gerencer
Oral Contraception And Cognition, Kathleen Gerencer
Electronic Theses and Dissertations
Oral contraception is currently used by over 100 million women worldwide. Women utilize contraception not only to prevent pregnancy but also to manage a wide range of health concerns, such as acne and polycystic ovarian syndrome. Although this medication has granted women bodily autonomy, helped them attain higher levels of education, and helped them enter the workforce in greater numbers, little is known about the consequences outside of the intended contraceptive effects, specifically the cognitive and behavioral consequences. Moreover, because doctors can prescribe contraception after the first menstrual cycle and during puberty, it’s possible that this critical window of development …
Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan
Nutrition As A Modifiable Risk Factor For Cognitive Decline: Associated Cognitive And Physical Health Changes, Taylor Mcmillan
Electronic Theses and Dissertations
Dementia is defined as gradual, progressive loss of cognitive functioning, greater than what is expected of normal aging, resulting in functional impairment. There are several types of dementia clinical syndromes that are accompanied by unique patterns of cognitive dysfunction and neuropathological changes. Alzheimer’s disease (AD) is the most common type of clinical dementia syndrome, accounting for approximately 60-70% of cases. Neuropathological mechanisms associated with AD include the disruption of the cholinergic system, accumulation of amyloid-beta plaques and hyperphosphorylated tau, as well as vascular pathology. Vascular pathology complicates the characterization of clinical and neuropathic changes in AD, as there becomes significant …
Risky Behavior As Motivated Emotion Regulation: A Mixed-Method Approach, Lyneé A. Herrera
Risky Behavior As Motivated Emotion Regulation: A Mixed-Method Approach, Lyneé A. Herrera
Electronic Theses and Dissertations
Engaging in risky health behaviors is a ubiquitous human experience that often marks developmental progression from adolescence into adulthood. While much previous research has framed risky behaviors in terms of negative legal, social, and public health consequences, less empirical work has been done on potential benefits of their engagement. A growing body of research has identified emotion regulation deficits as a significant driver of risky behavior engagement, suggesting that these behaviors may offer perceived emotional benefits when other regulation strategies are less accessible. Previous research has shown that emotional outcomes can be influenced by the regulation strategies one chooses to …
Interactive Computer-Based Simulations As Exploratory Learning Activities., Derek Mcclellan
Interactive Computer-Based Simulations As Exploratory Learning Activities., Derek Mcclellan
Electronic Theses and Dissertations
Typical college lectures follow a direct instruction framework, where instructors deliver a lecture, followed by an activity. Exploratory learning flips this routine by providing students with an activity prior to instruction. Research suggests that this inversion benefits students’ conceptual understanding and ability to transfer their knowledge. The majority of exploratory learning tasks in the literature are problem-solving activities. The current work investigates the use of computer-based simulations during exploratory learning, and whether manipulating the cognitive load of the activity impacts learning. In Experiment 1, undergraduate students (N=66) were randomly assigned to explore a simulation-based circuit construction activity prior …
False Memories Are Impacted By Semantic Pairing Of Drm Lists., Ryan Coleman
False Memories Are Impacted By Semantic Pairing Of Drm Lists., Ryan Coleman
Electronic Theses and Dissertations
In the DRM paradigm, experience of semantically related words leads to false memories of related words called critical lures. These false memories serve as evidence that the relationship between items in a DRM list contribute to an overall gist or central concept for the experience. The present studies aim to investigate whether the higher-order semantic relationship that exists between different DRM lists can also influence recognition memory. Study 1 compared memory confidence ratings for list items and critical lures to two metrics: “Temporal Contiguity”, how closely in time lists appeared to each other at encoding, and “Semantic Distance”, the semantic …
Reference Frames In Human Sensory, Motor, And Cognitive Processing, Dongcheng He
Reference Frames In Human Sensory, Motor, And Cognitive Processing, Dongcheng He
Electronic Theses and Dissertations
Reference-frames, or coordinate systems, are used to express properties and relationships of objects in the environment. While the use of reference-frames is well understood in physical sciences, how the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain the transition from egocentric (based on the observer) to exocentric (based outside the observer) reference-frames to account for the perception of relative motion. In a second project, we focus …
Adhd Symptoms And Inattentional Blindness In An Undergraduate Sample, Katherine Rose Matchett
Adhd Symptoms And Inattentional Blindness In An Undergraduate Sample, Katherine Rose Matchett
Electronic Theses and Dissertations
The relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and the phenomenon of inattentional blindness has received little empirical attention, with only a single published study on the topic. The purpose of the present study was to investigate individual differences in ADHD symptom severity in a non-clinical, undergraduate sample as they relate to susceptibility to inattentional blindness. Because research conducted in an individual differences framework requires the use of reliable measurement instruments, the present study also set out to develop and pilot a task that could induce inattentional blindness repeatedly and reliably in the same participants. The results showed that a) the measure …
Uncertainty Monitoring In Category Learning And Transfer, Rose Deng
Uncertainty Monitoring In Category Learning And Transfer, Rose Deng
Electronic Theses and Dissertations
Uncertainty is commonly experienced by many people during learning and decision making. Given that many career paths require the ability to monitor uncertainty, it’s important to understand how metacognitive processes influence cognitive performance. In attempts to explore how uncertainty monitoring impacts learning, three experiments were conducted. The first and second experiment utilized a categorization task in which participants explicitly learned to categorize Chemistry concepts. The third experiment assessed the impact of uncertainty monitoring on implicit learning and utilized a different task to tap into the implicit learning system. The present dissertation is one of few to investigate the role of …
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Electronic Theses and Dissertations
Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …
The Effect Of Typewriting Vs. Handwriting Lecture Notes On Learning: A Systematic Review And Meta-Analysis., Timothy Schaun Lau
The Effect Of Typewriting Vs. Handwriting Lecture Notes On Learning: A Systematic Review And Meta-Analysis., Timothy Schaun Lau
Electronic Theses and Dissertations
This study is a systematic review and meta-analysis of studies examining the effect of note-taking modality during lecture, that is, taking notes by hand using pen and paper vs. taking notes using a keyboard and computer, on learning among secondary and postsecondary students. I begin with a review of the literature and theoretical introduction to the theories and terms used. From a theoretical standpoint, there are strong reasons to believe that taking notes by hand might offer recall benefits relative to taking notes using a computer and keyboard. At the same time, I point out that one problem, which I …
Adverse Childhood Experiences And Quality Of Life: A Mediating Role Of Physical Activity And Executive Function, Loni Parrish
Adverse Childhood Experiences And Quality Of Life: A Mediating Role Of Physical Activity And Executive Function, Loni Parrish
Electronic Theses and Dissertations
ACEs have been associated with heightened risk for a range of chronic health problems, substance use, and cognition in adulthood (Center for Disease Control (CDC), 2019; Hinojosa et al., 2017). One potential protective factor is physical activity (McEwen, 2016; Wu et al., 2013). Physical activity is associated with sustaining overall health, improving mental health by reducing symptoms of depression and anxiety (Murri et al., 2019; Sharma et al., 2006; Tasci et al., 2019), and maintaining a healthy body weight and BMI (WHO, 2021). Therefore, this study examined whether barriers to physical activity, physical activity levels, and executive outcomes serve as …
Individual Characteristics Of Postsecondary Underachievement, Natasha Godkin
Individual Characteristics Of Postsecondary Underachievement, Natasha Godkin
Electronic Theses and Dissertations
Underachievement in postsecondary education has been a growing concern for educators and researchers. Higher education institutions have implemented early alert systems to identify students performing below standards. This early warning system has major limitations that confine it to an identification only approach. The current study aimed to investigate the psychometric properties of the Student Attitude Assessment Survey-R (SAAS-R) in a postsecondary sample. First, a confirmatory factor analysis validated the SAAS-R in a postsecondary sample. Predictive validity was then investigated by identifying students as underachieving or achieving based on responses to the SAAS-R and via a regression-based discrepancy model (ability vs. …
The Effects Of Rejection Sensitivity On Attention And Performance Monitoring Event-Related Potentials, Elizabeth Ridley
The Effects Of Rejection Sensitivity On Attention And Performance Monitoring Event-Related Potentials, Elizabeth Ridley
Electronic Theses and Dissertations
Rejection sensitivity (RS) can have significant effects on interpersonal relationships. Previous research has shown the negative social effects of RS, but less is known about the cognitive implications of having high levels of RS. The current study examined the effect of RS on various event-related potential (ERP) components associated with performance monitoring (error-related negativity, ERN; feedback-related negativity, FRN) and attention (P300; late positive potential, LPP). Participants completed a social or nonsocial Flanker task and an emotional Stroop task. Results showed an increased ERN on error trials for individuals with higher RS. Although the FRN, P300, and LPP were not influenced …
Effects Of Dissociation And Hyperarousal On Item And Association Memory, Naomi M. Wright
Effects Of Dissociation And Hyperarousal On Item And Association Memory, Naomi M. Wright
Electronic Theses and Dissertations
Dual representation theory (DRT) asserts that when an individual experiences an acutely stressful or traumatic event, encoding of memory of individual parts of an event (i.e., items) is enhanced, while connections between parts of an event (i.e., associations) is impaired due to peritraumatic changes in cognitive functioning. The current project sought to refine understanding of DRT by examining the differential effect of dissociation and hyperarousal, two common peritraumatic cognitive reactions, on memory for item and association information. Method: Using experimental methods from the cognitive study of memory, two studies evaluated how individual differences in cognitive states (Study 1) and experimentally …
An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios
An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios
Electronic Theses and Dissertations
Sport-specific practice of movement techniques is undoubtedly important in young athletes' sport performance. However, in sports that are more heavily reliant on open skills, cognitive factors, such as working memory (WM), attention, and spatial awareness, are more likely to become a barrier for proficiency than form or physical prowess. Nevertheless, the intricacies of the relationships that exist between these cognitive factors has gone relatively unexplored, particularly in the context of sport. The present research explored the impact of sport-specific experience on measures of WM, attentional control, and spatial awareness, and their interactions, through the lens of athletic expertise. Participants consisted …
The Effect Of State/Trait Rumination On A Prospective Memory Task Delivered Remotely Using A Real-Time And Repeated Approach, Iulia Niculescu
The Effect Of State/Trait Rumination On A Prospective Memory Task Delivered Remotely Using A Real-Time And Repeated Approach, Iulia Niculescu
Electronic Theses and Dissertations
Background. Prospective memory (PM) refers to the intention to perform a future task held in memory that is executed without any explicit prompts. PM may be negatively impacted by depression, but the mechanisms that drive this association remain unclear. One idea is that rumination increases the frequency of task-irrelevant thoughts, depleting attentional capacity, and thereby reducing PM accuracy and increasing response times. To date, no studies have examined the effects of state and trait rumination on PM using online testing to collect real-time data over time. Objectives. To examine the effect of (1) state and (2) trait rumination on a …
Capitalizing On Stress: Improving Affect And Self-Efficacy Through An Arousal Reappraisal Intervention, Angel Long
Capitalizing On Stress: Improving Affect And Self-Efficacy Through An Arousal Reappraisal Intervention, Angel Long
Electronic Theses and Dissertations
Stress is a non-specific reaction to the body (Jamieson et al., 2018), defined as a feeling of tension when one’s personal resources are taxed or exceeded (Folkman & Lazarus, 1985). Coping mechanisms for stress often focus on reducing associated features (Connor-Smith & Flachsbart, 2007). However, stress can produce challenge states, mindsets where individuals perceive personal resources as greater than situational demands (Jamieson et al., 2013). Challenge states are more likely to elicit positive behavior (Jamieson et al., 2018) and improved cognitive performance (Jamieson et al., 2010). One prospective mechanism to foster challenge states is arousal reappraisal, a cognitive mechanism …
Control, Alter, And Delete: Investigating The Manipulation Of Memory And Memorial Beliefs By Suspected Psychopaths In Interpersonal Relationships, Kendra Nespoli
Electronic Theses and Dissertations
Psychopaths are known to wreak havoc in the lives, careers, and relationships of people with whom they come into contact, triggering impacts that can extend for many years. To date, few studies have investigated the psychological tactics used by psychopaths to manipulate and control others in relationships. Previous research in the area of autobiographical memory has demonstrated that the decisions people make regarding belief in their memory for life events are influenced by feedback received from others. Social feedback has been shown to be a powerful influence in persuading others to revise beliefs about past events, particularly in the context …
The Continued Prohibition Of Cannabis & Racism At Canada’S Borders, Dara Vosoughi
The Continued Prohibition Of Cannabis & Racism At Canada’S Borders, Dara Vosoughi
Electronic Theses and Dissertations
Canada is one of the few jurisdictions in the world where cannabis for personal and recreational purposes is legal. Prior to October 17th 2018, the possession of any quantity of cannabis was a criminal offence, making individuals vulnerable to onerous criminal sanctions. The legislative act that resulted in the decriminalization and regulation of cannabis was framed as a means of advancing public health goals and reducing inequalities. Those once engaged in low level cannabis activities were no longer subject to criminal sanctions within Canada. However, the criminal status and practices upholding the prohibition of cannabis continues at Canada’s borders and …
The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen
The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen
Electronic Theses and Dissertations
The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …
Positive Body Image And Cognitive Processing Style, Brittney Dumas
Positive Body Image And Cognitive Processing Style, Brittney Dumas
Electronic Theses and Dissertations
Social media use among young people is ubiquitous and has been associated with body image concerns. Though prior work has overwhelmingly focused on “screen time,” increasing evidence highlights the role of subjective social media experiences in driving this association, rather than mere frequency of use. In the current study, body appreciation was tested as a trait-level variable that may protect women from the negative impact of appearance-focused fitspiration images, which have become common in social media platforms. Appearance schema activation and appearance-related self-discrepancy were examined as two social-cognitive processes in which self-protective tendencies may emerge. Fitspiration exposure predicted appearance schema …
Coherence, Travis Walthall
Coherence, Travis Walthall
Electronic Theses and Dissertations
COHERENCE is a series of oil paintings and pen drawings that explores open narratives, or different ways to read artwork. The paintings and drawings showcase harmony, or tension, between ambiguous and representational forms. The visual experience requires the viewer to create their own narrative and decipher forms to do so. COHERENCE is a psychological and aesthetic exhibition fueled from human experience— one of fragility, uncertainty, imperfection, beauty, faith and memories.
It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey
It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey
Electronic Theses and Dissertations
The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …
Veracious Verdicts: An Expansion Of Cognitive-Experiential Self-Theory In Jury Decision-Making Using Attribution Theory, Jade E. Larson
Veracious Verdicts: An Expansion Of Cognitive-Experiential Self-Theory In Jury Decision-Making Using Attribution Theory, Jade E. Larson
Electronic Theses and Dissertations
As a pillar in our judicial system, the courts utilize almost ten million citizens each year for jury service. As a result, the courts are faced with issues of inconsistency and unpredictability. This study aims to examine some factors that significantly influence jury decision-making by investigating cognitive experiential self-theory (CEST) as a jury decision-making model, unified with attribution theory to better predict verdict outcomes. An online survey was distributed to 121 participants. The respondents were asked to read a civil trial case presentation; they were then randomly divided into two conditions (high and low unrelated detail eyewitness testimony). The testimonies …
