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 …
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 …
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 …
Error-Related Negativity And Feedback-Related Negativity On A Reinforcement Learning Task, Elizabeth Ridley
Error-Related Negativity And Feedback-Related Negativity On A Reinforcement Learning Task, Elizabeth Ridley
Electronic Theses and Dissertations
Event-related potentials play a significant role in error processing and attentional processes. Specifically, event-related negativity (ERN), feedback-related negativity (FRN), and the P300 are related to performance monitoring. The current study examined these components in relation to subjective probability, or confidence, regarding response accuracy on a complicated learning task. Results indicated that confidence ratings were not associated with any changes in ERN, FRN, or P300 amplitude. P300 amplitude did not vary according to participants’ subjective probabilities. ERN amplitude and FRN amplitude did not change throughout the task as participants learned. Future studies should consider the relationship between ERN and FRN using …
The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones
The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones
Electronic Theses and Dissertations
Working memory (WM) is a crucial component of cognitive function that affects learning, reasoning, and problem solving, all of which are important for daily functioning. Therefore, addressing factors that can impact working memory, such as stress, are incredibly relevant to understanding WM efficiency. WM is an important component of higher order cognitive function and high WM capacity has been shown to be important for academic and occupational performance. Thus, understanding the relationship between stress-related factors and WM could aid in identifying strategies to mitigate the deleterious effects of stress on working memory. Although some previous research has indicated a negative …
Exploring The Moderating Effect Of Maternal Scaffolding On The Temperament - Language Development Relationship, Chelsea L. Robertson
Exploring The Moderating Effect Of Maternal Scaffolding On The Temperament - Language Development Relationship, Chelsea L. Robertson
Electronic Theses and Dissertations
Many studies have examined the relationship between a child’s temperament and its effect on his or her early language development. However, few studies have investigated the detrimental effects a child’s negative affectivity may have on their language development and potential ways these effects may be limited through parental behaviors. The current study aimed to investigate if physical or verbal maternal scaffolding behaviors moderated the effect negative affect has on language development. Although it was expected that maternal encouragement of physical activity would play a moderating role in the relationship between temperament and language development, no such relationship was found. One …
Faces, Locations, And Tools: A Proposed Two-Stimulus P300 Brain Computer Interface, Marissa R. Jones
Faces, Locations, And Tools: A Proposed Two-Stimulus P300 Brain Computer Interface, Marissa R. Jones
Electronic Theses and Dissertations
Brain Computer Interface (BCI) technology can be important for those unable to communicate due loss of muscle control. The P300 Speller allows communication at a rate up to eight selections per minute. Given this relatively slow rate of communication highly accurate classification is of great importance. Previous studies have shown that alternative stimuli (e.g., faces) can improve BCI speed and accuracy. The present study uses two new alternative stimuli, locations and graspable tools in a two-stimulus paradigm. Functional MRI studies have shown that images of familiar locations produce brain responses in the parahippocampal place area and graspable tools produce brain …

Video Game Engagement, Gender, And Age: Examining Similarities And Differences In Motivation Between Those Who May Or May Not Play Video Games, Joseph Camarata
Electronic Theses and Dissertations
This research aims to fill a research gap by examining video games to explore whether gender, age, or hours played per week would exert any influence on the information of those who may or may not play video games. Mood Management Theory and Uses and Gratification Theory were used as the theoretical foundation for this study. Four-hundred-three East Tennessee State University students who received the survey via email were asked to voluntarily participate in a survey about their motivations behind playing video games. Results from MANOVA showed that the motivations of male participants on video games were significantly higher than …
Improving The P300-Based Brain-Computer Interface By Examining The Role Of Psychological Factors On Performance, Samantha A. Sprague
Improving The P300-Based Brain-Computer Interface By Examining The Role Of Psychological Factors On Performance, Samantha A. Sprague
Electronic Theses and Dissertations
The effects of neurodegenerative diseases such as amyotrophic-lateral sclerosis (ALS) eventually render those suffering from the illness unable to communicate, leaving their cognitive function relatively unharmed and causing them to be “locked-in” to their own body. With this primary function compromised there has been an increased need for assistive communication methods such as brain-computer interfaces (BCIs). Unlike several augmentative or alternative communication methods (AACs), BCIs do not require any muscular control, which makes this method ideal for people with ALS. The wealth of BCI research focuses mainly on increasing BCI performance through improving stimulus processing and manipulating paradigms. Recent research …

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan
Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan
Electronic Theses and Dissertations
Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …
The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague
The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague
Electronic Theses and Dissertations
Amyotrophic lateral sclerosis and other neurodegenerative disorders can cause individuals to lose control of their muscles until they are unable to move or communicate. The development of brain-computer interface (BCI) technology has provided these individuals with an alternative method of communication that does not require muscle movement. Recent research has shown the impact psychological factors have on BCI performance and has highlighted the need for further research. Working memory is one psychological factor that could influence BCI performance. The purpose of the present study is to evaluate the relationship between working memory and brain-computer interface performance. The results indicate that …
