The Relationship Between Cognitive Control And Individual Differences In Working Memory Capacity: A High-Density Eeg Study, Conghao Gao

All NMU Master's Theses

Empirical evidence has suggested a close relationship between human working memory capacity and cognitive control approaches. Proactive control refers to the anticipatory, sustainable maintenance of cognitive control process. However, the relationship between higher working memory capacity and the use of proactive cognitive control has been inconsistent. Understanding the neural bases would substantially expand our current understanding of cognitive control and working memory models. Specifically, the examination of P3b amplitude, part of the event-related potential, evoked by a cue would provide further understanding in neural mechanisms of cognitive control. The current study examined participants’ cognitive control approaches and their electrocortical activity …

From Stranger To Self: The Role Of Familiarity In Modulating The N170 And N250 Erp Components, Tabish Gul

Dissertations

This study investigated how varying levels of face familiarity modulate the N170 and N250 event-related potential (ERP) components, two neural markers of face perception and recognition. While the N250 is widely considered familiarity-sensitive, the N170 has traditionally been linked to the structural encoding stage of face perception. However, recent research suggests that face familiarity may also influence N170 amplitude and latency. While most previous studies have compared up to three familiarity levels, the present study examined five levels of familiarity: own face, friend’s face, famous face, experimentally familiar face, and unfamiliar face. Twenty-six participants viewed face images while completing a …

Eeg And Media Multitasking: Adhd As A Moderating Factor, Xiaoying Guo

Theses and Dissertations

Media use has become an integral part of everyday life. It has risen dramatically over the past century with the advent of television, computers, and digital platforms, and more recently, it has been characterized by individuals using multiple devices simultaneously (Bushman & Anderson, 2001; Nielsen Media Research, 1998; Rideout & Robb, 2019, 2021). Media multitasking (MMT) has been linked to cognitive control challenges and attentional difficulties. This study examined EEG workload (Fz theta/Pz alpha ratio), survey accuracy, and ADHD traits (ASRS v1.1) in 33 adult participants across baseline and single-versus dual-media conditions. Results indicated that mental workload was significantly higher …

Exploring The Processing Of Objects, Settings, And Global Properties In Natural Auditory Scenes, Margaret A. Mcmullin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our auditory system has a remarkable ability to make sense of complex environments, allowing us to identify what we are hearing and where sounds come from. This process of auditory scene analysis is essential for situational awareness, decision-making, and effective communication in daily life. While much is known about how listeners segregate and identify individual sound sources (e.g., voices), less is understood about how global properties of a scene (e.g., openness, naturalness) contribute to perception. This dissertation examined how object- and setting-level information in natural auditory scenes are processed, and whether they rely on distinct or overlapping mechanisms. In Experiment …

Using Eeg To Measure Attentional Spreading Across Objects, Dawson L. Green, Michael Pratte

Honors Theses

Abstract: Attention may not solely be restricted to a spatial area or a feature of an object, but rather can “spread” across all parts of an object in space, enhancing the processing of its features collectively (Duncan, 1984). This phenomenon suggests that attention operates at the level of whole objects, enhancing the representation of all features associated with the attended object while suppressing competing stimuli. Building on this object-based framework, the present thesis examines the functional and neural dissociation between attention and awareness using steady-state visually evoked potentials (SSVEPs) as a frequency-tagging method in EEG. Leveraging the high temporal resolution …

Expediting Tool-Use Learning: Effects Of Non-Invasive Neurostimulation Of The Left Anterior Supramarginal Gyrus, Kamila Haliru

Honors Thesis

The left anterior supramarginal gyrus (aSMG) has been implicated as an important brain region in tool use. While anodal transcranial Direct Current Stimulation (atDCS) over the primary motor cortex (M1) has been shown to facilitate skilled tool use, the effects of aSMG stimulation remain largely unexplored. Using a chopstick-marble paradigm, this thesis examined whether atDCS to the left aSMG would enhance tool-use learning. Electroencephalography (EEG) was concurrently recorded to assess atDCS-dependent changes to the beta and gamma frequency bands. Our results demonstrated that atDCS over the left aSMG significantly expedited tool-use learning and was associated with increased gamma band activity …

Perceiving, Processing, And Evaluating Infant Facial Affect In Potential Parents: An Erp Study, Tiffany Bonnagio

Electronic Theses and Dissertations

Evidence for differences between assigned female at birth (AFAB) and assigned male at birth (AMAB) perceiving, processing, and evaluating infant faces has been mixed. The current study examined whether expected parental self-efficacy (EPSE) and desire for children predicts event-related potentials (ERPs) to infant facial affect in potential parents. No scale for EPSE exists. Therefore, we reworded the Perceived Maternal Parental Self-Efficacy scale from present to future tense. There was no correlation with EPSE scores, ERPs, or behavioral data. No difference was found between AFAB and AMAB in accurately evaluating infant faces; however, AFABs responded more quickly. ERP data revealed significantly …

Music And Linguistic Semantic Anomalies: An Erp Study Of Integration And Expectancy On Predictive Processing Of Harmonic Music During A Self-Paced Reading Task, Jason Schmidt Avendaño

USF Tampa Graduate Theses and Dissertations

Music, like language, is widely known to communicate emotional meaning. Yet, much debate is still on whether musical information uses shared neural resources similar to language. Past experiments using only Reaction Time (RT) measures have found that when syntactic complexities in language coincide with harmonic music violations, enhanced processing difficulties suggest shared neurocognitive resources. However, researchers failed to find similar interactions in semantic word conditions. This experiment examined event-related potentials (ERPs) to index word recognition processes related to semantic expectancy generation (N400) and integration (LPC & FP) in musicians and nonmusicians. Unlike RT measures, ERP components allow us to understand …

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 …

The Influence Of Visual Perspective On The Cognitive Effort Required For Mental Representation, Jeffrey P. Hong

Theses and Dissertations (Comprehensive)

Mental representation is the process by which an individual simulates an event in their mind’s eye. This process is the foundation of the ability to remember the past, engage in prospective thinking, or imagine fictitious scenarios. An individual can mentally represent any event through their own eyes—the first-person perspective or from the viewpoint of an external observer—the third-person perspective. The perspective of representation influences outcomes related to memory, visuospatial processing, affect, social cognition, clinical diagnoses, and language processing. In turn, an individual’s tendency to favour either perspective is shaped by related factors.

The current research consists of four experiments, designed …

Voluntary Action And Conscious Intention, Jake Gavenas

Computational and Data Sciences (PhD) Dissertations

Traditional experimental methodology in neuroscience involves comparing responses to different stimuli to make inferences about the human brain. However, human volition entails making decisions and acting in a manner that is underdetermined by the external environment. Investigations of the neuronal basis of volition have led to new controversies regarding the existence of free will, and offer potential directions for medical treatments of disorders such as addiction, akinetic mutism, and locked-in syndrome. However, because volition experiments leave aspects of responses “up to” participants, neuroscientists must utilize computational techniques such as modeling, simulation, and advanced analyses to progress our understanding of human …

Does Cleft Repair Surgery Restore Normal Visual And Neural Responses To Infant Faces?, Rachael Leanne Kee

Cal Poly Humboldt theses and projects

Infant faces readily capture our attention and elicit enhanced neural processing, likely due to their evolutionary importance in facilitating bonds with caregivers. Infant facial malformations are associated with a lower degree of parental investment and have been shown to negatively impact early infant-caregiver interactions. Cleft lip or cleft palate is a common facial malformation, estimated to affect 1 in 700 live births worldwide, that is associated with altered visual and neural processing as compared to normal infant faces. Importantly, it is not yet known how craniofacial repair surgery impacts responses to these faces. The current study uses eye tracking and …

Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson

Honors Thesis

Neurofeedback training has been a recent field of study in neuroscience, as a potential way to increase focus, and possibly boost cognitive performance. Most studies utilize a course of neurofeedback training sessions to find positive results in decreasing ADHD symptoms, depression symptoms, as well as further cognitive changes. In this study, we aim to determine the efficacy of a single session of neurofeedback training in increasing cognitive performance. To do so, we randomly separated 42 volunteers into either a control or experimental group. The experimental group participated in an n-back task both before and after an alpha neurofeedback training session, …

Classical Conditioning Of Cognitive States, Arthur Burns

Neuroscience Honors Papers

Classical conditioning has been a fundamental concept and practice throughout the history of psychology. While classical conditioning traditionally seeks to elicit target behaviors in correlation to specific stimuli, we sought to do the same with cognitive states in place of behaviors. Specifically, we wanted to determine the effectiveness of conditioning states of cognitive arousal in human participants in conjunction with cues presented in a designed learning task. We designed a cognitive task specifically for this research, referred to as “the Tone Pitching Task”, which utilized a combination of working memory and mental processing in order to elicit cognitive arousal and …

The Electrophysiological Correlates Of Text Integration And Direct Vs. Indirect Articles: A Centralized And Lateralized Examination, Deanna C. Hall

Theses and Dissertations (Comprehensive)

As we read, we develop mental models of the discourse content called situation models. Situation models are integral to how we keep track of information, and to do so in an ongoing event incoming information needs to be integrated into the model or discarded. The type of information being presented, and its relation to prior data, impacts how that new information is processed. The current research examined discourse passages containing concepts that were either previously mentioned (match), mentioned with a general term (general category), unmentioned in lieu of another concept (mismatch), or completely unmentioned previously (indeterminate), and examined how these …

Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …

The Effect Of A Mindfulness-Based Intervention On Attention And Cognitive Control As A Function Of Smartphone Notifications., Joshua D. Upshaw

Graduate Theses and Dissertations

Barriers to accessing mobile technology, particularly smartphones, have decreased substantially since the iPhone’s release in 2007, resulting in increased ownership and usage across all ages, genders, and races. Despite their ubiquity in our society, relatively little empirical work has investigated the influence of smartphones on our higher order executive functioning. Prior work has linked smartphone use with impaired cognitive control during cognitively demanding tasks, especially in heavier smartphone users. The goals of the current study were twofold. First, the study aimed to examine the effects of smartphone notifications on cognitive control and attention. And second, to determine the effects of …

Frontal Alpha Wave Asymmetry In Regard To Affect, Monica Leigh Sewell

All Master's Theses

This study examines frontal alpha brain wave asymmetry (FAA) in relation to emotion processing. Previous research has shown that differences between left versus right FAA could exhibit a neurological marker for emotional intelligence (EI), mental health, and stress. Behavioral data were collected using Profile of Emotional Competence Questionnaire, Perceived Stress Questionnaire, Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7. This was followed by a series of resting EEG recordings. This study hypothesizes that participants who are mentally healthy, have higher EI scores and lower stress will display greater left FAA. The hypothesis is partially supported; participants with depression had greater …

Emotion Regulation And N2 Amplitude During A Go/Nogo Task: An Erp Study, Emily Tolar

Psychological Science Undergraduate Honors Theses

Emotion regulation is how people respond to and manage their reactions to life experiences, including resolving conflict between variable responses. Past research has associated the N2, an event-related potential associated with resolving response conflict, with both emotion regulation and negative emotion. However, to the best of our knowledge, no one has assessed if different emotion-regulation strategies are differentially associated with N2 activation. To assess this question, we conducted an EEG study with 147 participants. Participants completed the Cognitive Emotion Regulation Questionnaire (CERQ) and then played the go/no-go game as their EEG data was collected. The relationship between N2 amplitude and …

Are Individual Differences In Media Multitasking Habits Associated With Changes In Brain Activation: An Erp Investigation Of Multitasking And Cognitive Control, Morgan Middlebrooks

Graduate Theses and Dissertations

As the number of mobile phone users grows, understanding the impact of multiple streams of media on media multitasking and related neural correlates is especially pertinent. This research aims to understand the association between media multitasking tendencies on the neural correlates underlying cognitive control using event-related potentials (ERPs). Specifically, we were interested in the N2 and P3, ERPs that measure neural activation underlying aspects of cognitive control. Based on the literature, we predicted that participants who have high media multitasking scores would show more negative N2 activation and more positive P3 activation than their low media multitasking counterparts during an …

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

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 …

Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico

All Master's Theses

The present research evaluated the effect of mood and individual differences on the regulatory process of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an ERP analysis. In addition, the current study compared the modulation of the LPP to the self-reported mood of the participants and their individual differences in regulation ability through scores of a self-report emotion regulation questionnaire. The latent positive potentials from an emotion regulation task …

Visual Modulation Of Resting State Α Oscillations, Kelly Webster, Tony Ro

Publications and Research

Once thought to simply reflect passive cortical idling, recent studies have demonstrated that α oscillations play a causal role in cognition and perception. However, whether and how cognitive or sensory processes modulate various components of the α rhythm is poorly understood. Sensory input and resting states were manipulated in human subjects while electroencephalography (EEG) activity was recorded in three conditions: eyes-open fixating on a visual stimulus, eyes-open without visual input (darkness), and eyes-closed without visual input (darkness). We show that α power and peak frequency increase when visual input is reduced compared to the eyes open, fixating condition. These results …

The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations and Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

Competitive Frontoparietal Interactions Mediate Implicit Inferences, Martijn E. Wokke, Tony Ro

Publications and Research

Frequent experience with regularities in our environment allows us to use predictive information to guide our decision process. However, contingencies in our environment are not always explicitly present and sometimes need to be inferred. Heretofore, it remained unknown how predictive information guides decision-making when explicit knowledge is absent and how the brain shapes such implicit inferences. In the present experiment, 17 human participants (9 females) performed a discrimination task in which a target stimulus was preceded by a predictive cue. Critically, participants had no explicit knowledge that some of the cues signaled an upcoming target, allowing us to investigate how …

Neurological Correlates Of The Dunning-Kruger Effect, Alana Lauren Muller

Electronic Theses, Projects, and Dissertations

The Dunning-Kruger Effect is a metacognitive phenomenon in which individuals who perform poorly on a task believe they performed well, whereas individuals who performed very well believe their performance was only average. To date, this effect has only been investigated in the context of performance on mathematical, logical, or lexical tasks, but has yet to be explored for its generalizability in episodic memory task performance. We used a novel method to elicit the Dunning-Kruger Effect via a memory test of item and source recognition confidence. Participants studied 4 lists of words and were asked to make a simple decision about …

Behavioral And Neural Correlates Of Misses During Cued Recall, Lindsey Sirianni

Electronic Theses, Projects, and Dissertations

Recognition memory is thought to rely upon both recollection and familiarity. When people recall an episode from the past it is generally considered to reflect the memory process of recollection. Therefore, if people can successfully recall an item, they should be able to recognize it. However, in cued recall paradigms of memory research, participants sometimes correctly recall a studied target word in the presence of a strong semantic cue but then fail to recognize that word as actually having been studied. This paradox and underlying cognitive processes have been minimally studied by scientists, leaving this phenomenon poorly understood. Extant research …

An Erp Investigation Of Reward Signals For Differing Classes Of Reinforcing Stimuli, Darin R. Brown

Psychology ETDs

In order to successfully traverse an actively complex environment, an agent is required to learn from the consequences of their actions. For over a century, models of behavior have been developed demonstrating these consequence-based learning systems. More recently, underlying biological systems have been found to adhere to these constructs of learning. The electroencephalographic signal known as the Reward Positivity (RewP) is thought to reflect a dopamine-dependent cortical signal specific to reward receipt. Importantly, this signal has been shown to adhere to an axiomatic (rule-like) positive reward prediction error, whereby it is evoked following outcomes that are better than expected. These …
