Exploring The Relationships Among Adhd, Generalized Anxiety Disorder, And Emotion Regulation, Anna S. Hall Jan 2024

Exploring The Relationships Among Adhd, Generalized Anxiety Disorder, And Emotion Regulation, Anna S. Hall

Electronic Theses and Dissertations

This study investigated the relationships among Attention-Deficit Hyperactivity Disorder (ADHD) symptoms and common comorbid struggles for clients, including Generalized Anxiety Disorder (GAD) symptoms, and executive functions, especially emotion regulation. ADHD and GAD are prevalent mental health conditions, are commonly comorbid with each other, and are both correlated with relative deficits in executive functions. Executive functions comprise higher-order cognitive processes like planning, inhibition, initiation, and monitoring, as well as emotion regulation. Prior research established connections among ADHD symptoms, GAD symptoms, and emotion regulation but did not examine which specific facets of emotion regulation were most relevant. The current study aimed to …


Examining Task-Related Differences In The Error-Related Negativity (Ern) As A Function Of Cognitive Control Strategy And Trait Anxiety, Russell Mach Dec 2023

Examining Task-Related Differences In The Error-Related Negativity (Ern) As A Function Of Cognitive Control Strategy And Trait Anxiety, Russell Mach

Graduate Theses and Dissertations

Anxiety disorders pose a significant challenge to daily living, workplace productivity, and healthcare systems. Extant research supports empirical links between anxiety and brain-level error monitoring. The ERN – or error-related negativity – is one widely studied correlate of anxious symptomatology. Relatively stable individual differences in the ERN are inferred from electroencephalogram (EEG) recordings time-locked to the commission of mistakes. However, the assumed interchangeability of ERNs elicited under different experimental conditions has not been thoroughly evaluated. Canonical tasks for measuring the ERN may cue specific strategies for cognitive control, possibly producing divergent findings across studies. In a sample of 108 undergraduate …


Electrophysiological Signatures Of Error Commission And Adjustment, Mark Lavelle Aug 2023

Electrophysiological Signatures Of Error Commission And Adjustment, Mark Lavelle

Psychology ETDs

Errors inhibit attainment of our goals. Behavioral and neural adjustments following errors are often framed as independent aspects of decision-making termed threshold (or response caution) and drift rate (or evidence accumulation). We replicated and extended the association of single-trial threshold with frontal midline theta power from the previous trial, as measured from EEG in 21 participants completing a flankers task. Surprisingly, theta power also predicted next trial drift rate. Variation in brightness of the stimuli was associated with drift rate and various EEG and time-frequency features, including posterior alpha/beta power. Posterior alpha/beta power also correlated with drift rate and significantly …

Changes In Cognitive Control Following A Novel Resilience-Focused Nursing Educational Program: An Exploratory Study, Shannon Dames, Wendy Young, Olave Krigolson, Kelly Zhang, Lincoln Stoller, Robyn Bartle

Quality Advancement in Nursing Education - Avancées en formation infirmière

Patient care is currently challenged by various factors including stress and nurse fatigue that can negatively impact nurses’ health and patient safety. Emotional exhaustion and burnout among nurses are at an all-time high. Canadian nurses are reporting clinical rates of depression, anxiety, and panic at disproportionately higher rates than other public safety personnel. Innovative educational programs are desperately needed to mitigate stress and relieve distress, which will ultimately promote a healthier and more productive workforce. Little is known about the effectiveness of research informed cognitive control education within a community of practice (COP) to help nurses and nursing students process …


Individual Differences In Structure Learning, Philip Newlin May 2022

Individual Differences In Structure Learning, Philip Newlin

Theses and Dissertations

Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …


Cognitive Control Processes In Behavior Therapy For Youth With Tourette’S Disorder, Joseph F. Mcguire, Alexandra Sturm, Emily J. Ricketts, Gabrielle E. Montalbano, Susanna W. Chang, Sandra K. Loo, Douglas W. Woods, James T. Mccracken, John Piacentini Mar 2022

Cognitive Control Processes In Behavior Therapy For Youth With Tourette’S Disorder, Joseph F. Mcguire, Alexandra Sturm, Emily J. Ricketts, Gabrielle E. Montalbano, Susanna W. Chang, Sandra K. Loo, Douglas W. Woods, James T. Mccracken, John Piacentini

Psychology Faculty Research and Publications

Background

Cognitive control processes are implicated in the behavioral treatment of Tourette’s disorder (TD). However, the influence of these processes on treatment outcomes has received minimal attention. This study examined whether cognitive control processes and/or tic suppression predicted reductions in tic severity and treatment response to behavior therapy.

Method

Fifty-three youth with TD or a pervasive tic disorder participated in a randomized wait list-controlled trial of behavior therapy. Following a baseline assessment to evaluate psychiatric diagnoses, tic severity, and cognitive control processes (e.g., response selection, inhibition, and suppression), youth were randomly assigned to receive eight sessions of behavior therapy ( …


The Influence Of Emotion Regulation And Neural Cognitive Control On Distress Tolerance, Alicia L. Milam Dec 2021

The Influence Of Emotion Regulation And Neural Cognitive Control On Distress Tolerance, Alicia L. Milam

Psychology Theses & Dissertations

Tolerance of negative emotions has been associated with transdiagnostic negative mental health outcomes. Theory and research implicate emotion regulation and cognitive control as factors in tolerance of negative emotions. But their unique contributions to tolerance of negative emotions and interdependency have been unclear due to methodological limitations. This study aimed to explicate cognitive and emotional factors affecting distress tolerance in a non-clinical sample of emerging adults. Undergraduate psychology students completed self-report measures of emotion regulation ability and tolerance of negative emotions. The N2 ERP component elicited by a Go-NoGo task was also used as a neurophysiological marker of cognitive control …


Altered Network Organization And Screen Time Use In Childhood Attention-Deficit / Hyperactivity Disorder (Adhd), Elizabeth Jane Hawkey Aug 2021

Altered Network Organization And Screen Time Use In Childhood Attention-Deficit / Hyperactivity Disorder (Adhd), Elizabeth Jane Hawkey

Arts & Sciences Electronic Theses and Dissertations

Introduction: Symptoms of attention-deficit/hyperactivity disorder (ADHD) have been associated with alterations in functional connectivity involving networks in the developing brain that support optimal cognitive control. However, a clear profile of altered connectivity has yet to emerge, and it remains unclear whether changes in behavioral patterns such as screen time (ST) contribute to ADHD symptomatology and altered connectivity in networks that support cognitive control. The current study examined connectivity between large-scale networks associated with cognitive control (CC), measures of executive function (EF) which index CC, and ST in children with ADHD. Methods: Our sample included 11,874 children (ages 9-11, 52% male) …


Inducing Proactive Control With High Load Ax-Cpt, Mina Selim Aug 2021

Inducing Proactive Control With High Load Ax-Cpt, Mina Selim

Electronic Theses, Projects, and Dissertations

A central hypothesis of cognitive control is that goal maintenance operates via two distinct modes: proactive control and reactive control (Braver, Gray, & Burgess, 2007). Individuals using a proactive strategy, focus on actively maintaining goal-relevant information in memory, whereas reactive individuals store goal-relevant information and retrieve it when cues are present. This theoretical framework for understanding the sources of variation in cognitive control is termed the dual mechanisms of control (DMC). When compared to high working memory capacity (WMC) individuals, low WMC individuals tend to utilize reactive control more often. However, some factors influence an individuals’ bias towards one type …


Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward May 2021

Neural Correlates Underlying The Interactions Between Anxiety And Cannabis Use In Predicting Motor Response Inhibition, Richard Ward

Theses and Dissertations

The ability to effectively withhold an inappropriate response is a critical feature of cognitive control. Prior research indicates alterations in neural processes required for motor response inhibition in anxious individuals, including those with posttraumatic stress disorder (PTSD), and those who engage in regular cannabis use. However, thus far most research has examined how anxiety-related symptoms and cannabis use influence response inhibition in isolation of one another. The current study examined the interactions between anxious symptomology and recent cannabis use in a sample that recently experienced a traumatic event using functional magnetic resonance imaging (fMRI) during the completion of a Stop-Signal …


The Development Of Reward Processing And Risky Behaviors In The Brain, Michelle L. Ramos Mar 2021

The Development Of Reward Processing And Risky Behaviors In The Brain, Michelle L. Ramos

FIU Electronic Theses and Dissertations

Adolescence is a period of heightened risk taking which can lead to many negative consequences. This increased risk taking may be related to developmental changes in the reward processing system in the brain. The current study proposes to investigate individual differences in the development of the reward processing system as well as cognitive-based regulatory processes in the developing brain, and how heterogeneity in neural and autonomic activity related to these processes may predict risk-taking behavior. Despite crucial developmental changes in the reward system leading to hypersensitivity to reward, there is great variability in risk-taking and sensation seeking behaviors seen in …


Is There Evidence For Cross-Domain Congruency Sequence Effect? A Replication Of Kan Et Al. (2013), Balazs Aczel, Marton Kovacs, Miklos Bognar, Bence Palfi, Andree Hartanto, Sandersan Onie, Lucas E. Tiong, Thomas Rhys Evans Mar 2021

Is There Evidence For Cross-Domain Congruency Sequence Effect? A Replication Of Kan Et Al. (2013), Balazs Aczel, Marton Kovacs, Miklos Bognar, Bence Palfi, Andree Hartanto, Sandersan Onie, Lucas E. Tiong, Thomas Rhys Evans

Research Collection School of Social Sciences

Exploring the mechanisms of cognitive control is central to understanding how we control our behaviour. These mechanisms can be studied in conflict paradigms, which require the inhibition of irrelevant responses to perform the task. It has been suggested that in these tasks, the detection of conflict enhances cognitive control resulting in improved conflict resolution of subsequent trials. If this is the case, then this so-called congruency sequence effect can be expected to occur in cross-domain tasks. Previous research on the domaingenerality of the effect presented inconsistent results. In this study, we provide a multi-site replication of three previous experiments of …


Seeking Control During Uncontrollable Times: Control Abilities And Religiosity Predict Stress During Covid-19, Shi Ann Shuna Khoo, Wei Xing Toh, Hwajin Yang Feb 2021

Seeking Control During Uncontrollable Times: Control Abilities And Religiosity Predict Stress During Covid-19, Shi Ann Shuna Khoo, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

The COVID-19 pandemic has created an urgent need to understand the protective factors that can buffer individuals against psychological distress. We employed a latent-variable approach to examine how control-related factors such as religiosity, self-control, cognitive control, and health locus of control can act as resilience resources during stressful periods. We found that cognitive control emerged as a protective factor against COVID-19-related stress, whereas religiosity predicted a heightened level of stress. These results provide novel insights into control factors that can safeguard individuals' psychological well-being during crises such as a pandemic.


Proactive And Reactive Cognitive Control Under Threat Of Unpredictable Shock: A Combined Eye-Tracking And Eeg Study Using Multilevel Modeling, Salahadin Lotfi Dec 2020

Proactive And Reactive Cognitive Control Under Threat Of Unpredictable Shock: A Combined Eye-Tracking And Eeg Study Using Multilevel Modeling, Salahadin Lotfi

Theses and Dissertations

We are constantly bombarded by environmental distractors in daily life which interfere with internal, ongoing goals, thus cognitive control processes need to be in place to adapt to maintain these goals in light of the environmental demands. These cognitive processes (generally referred to cognitive control) are thought to be adjusted reactively or proactively to deal with distractors. There is little evidence on how state anxiety dynamically interacts with these two modes of cognitive control. Taking advantage of a multimodal methodology, through two experiments, we replicated existing findings of reactive and proactive control processes via utilizing a Flanker task in a …


Dual Mechanisms Of Cognitive Control: An Eye Tracking Study, Kyle Mobly Dec 2020

Dual Mechanisms Of Cognitive Control: An Eye Tracking Study, Kyle Mobly

Electronic Theses, Projects, and Dissertations

The purpose of the present study was to attempt to provide an ocular signature for the dual mechanisms of cognitive control (proactivity and reactivity) by utilizing an eye tracker to record gaze patterns while participants were administered a modified version of the AX-CPT 40. Additionally, we sought to clarify whether context updating or maintenance was responsible for the higher Total Visit Duration (TVD) on the cue location during the ISI that was found in previous studies by providing both a short (1.5 seconds) and long (3 seconds) ISI length. This allowed us to disentangle context updating from maintenance by removing …


Are Individual Differences In Media Multitasking Habits Associated With Changes In Brain Activation: An Erp Investigation Of Multitasking And Cognitive Control, Morgan Middlebrooks Dec 2020

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 …


The Impact Of Task Load On Neural Entrainment To Attended Speech: A Dual-Task Magnetoencephalography (Meg) Paradigm, Michelle Tamar Kassel Aug 2020

The Impact Of Task Load On Neural Entrainment To Attended Speech: A Dual-Task Magnetoencephalography (Meg) Paradigm, Michelle Tamar Kassel

Theses and Dissertations

Speech comprehension in a noisy environment requires active cognitive control mechanisms to select the relevant speech signal while filtering out irrelevant distractions. When processing speech in a multitask scenario, neural resources underlying cognitive control are considerably burdened and interfering information becomes more difficult to ignore. The present study utilized magnetoencephalography (MEG) to investigate the impact of multitasking on selective attention to speech. Twenty healthy adults performed a multitask paradigm with varying levels of both competing auditory distraction and concurrent visual working memory load. While increased visual working memory load was associated with reduced selective attention to speech in both the …

Effects Of Anodal Tdcs On Neural Correlates Of Cognitive Control In Mild-To-Moderate Traumatic Brain Injury, Nickolas A. Mertens Apr 2020

Effects Of Anodal Tdcs On Neural Correlates Of Cognitive Control In Mild-To-Moderate Traumatic Brain Injury, Nickolas A. Mertens

Psychology ETDs

Traumatic brain injury is a worldwide epidemic and currently there is no successful treatment to combat the cognitive deficits sustained from a mmTBI. The goal of this analysis is to determine if active tDCS paired with cognitive training can aid in an individual’s recovery on one specific consequence of mmTBI: cognitive control. To examine this novel treatment on cognitive control, EEG was recorded, and FM-theta activity collected from electrode FCz was analyzed. Three analyses were run to address the hypotheses of the present study: 1. A cluster analysis; 2. A series of repeated-measures ANOVAs; and 3. A series of multiple …


Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez Nov 2019

Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez

Psychology: Faculty Scholarship

The Iowa Gambling Task (IGT) is a popular method for examining real-life decision-making. Research has shown gender related differences in performance, in that men consistently outperform women. It has been suggested that these performance differences are related to decreased emotional control in women compared to men. Given the likely role of emotion in these gender differences, in the present study, we examine the effect of a humor induction on IGT performance and whether the effect of humor is moderated by gender. IGT performance and parameters from the Expectancy Valence Model (EVM) were measured in 68 university students (34 men; mean …


Memory-Guided Selective Attention: An Instance Theory Of Automatic Attentional Control, Nicholaus Paul Brosowsky Sep 2019

Memory-Guided Selective Attention: An Instance Theory Of Automatic Attentional Control, Nicholaus Paul Brosowsky

Dissertations, Theses, and Capstone Projects

Cognitive control enables flexible goal-directed behavior via attention and action selection processes that prioritize goal-relevant over irrelevant information. These processes allow us to behave flexibly in the face of contradicting or ambiguous information and update behavior in response to the changing environment. Furthermore, they are thought to be in direct opposition to learned, automatic processing in that they enable us to disregard learned behaviors when they are inconsistent with our current goals. The strict dichotomy between stimulus-driven and goal-driven influences, however, has downplayed the role of memory in guiding attention. The position forwarded in this thesis is that a memory-based …


Cognitive Control And Context Maintenance In Individuals With Obsessive-Compulsive Disorder (Ocd), Lindsay Morgan Fruehauf Jun 2019

Cognitive Control And Context Maintenance In Individuals With Obsessive-Compulsive Disorder (Ocd), Lindsay Morgan Fruehauf

Theses and Dissertations

Context maintenance, an aspect of cognitive control, is the internal representation and utilization of task-relevant information that helps achieve task goals. Alterations in context maintenance may be responsible for the cognitive difficulties seen in people with obsessive-compulsive disorder (OCD). We used two tasks designed to measure context maintenance: a) the cued-Stroop, a single-trial version of Golden’s Stroop test that varies the cue for each trial (color-naming or word-reading), and b) the AX-CPT task, a continuous performance task that has participants respond to an “A” only when followed by an “X,” with all other non-target trials labeled as AY, BX, and …


Turning Down The Heat: Neural Mechanisms Of Cognitive Control For Inhibiting Task-Irrelevant Emotional Information During Adolescence, Marie T. Banich, Harry R. Smolker, Hannah R. Snyder, Jarrod A. Lewis-Peacock, Detre Godinez, Tor D. Wager, Benjamin L. Hankin Mar 2019

Turning Down The Heat: Neural Mechanisms Of Cognitive Control For Inhibiting Task-Irrelevant Emotional Information During Adolescence, Marie T. Banich, Harry R. Smolker, Hannah R. Snyder, Jarrod A. Lewis-Peacock, Detre Godinez, Tor D. Wager, Benjamin L. Hankin

Graduate School of Professional Psychology: Faculty Scholarship

One major question in the cognitive neuroscience of cognitive control is whether prefrontal regions contribute to control by upregulating the processing of task-relevant material or by downregulating the processing of task-irrelevant material. Here we take a unique approach to addressing this question by using multi-voxel pattern analysis, which allowed us to determine the degree to which each of the task-relevant and task-irrelevant dimensions of a stimulus are being processed in posterior cortex on a trial-by-trial basis. In our study, adolescent participants performed an emotion word – emotional face Stroop task requiring them to determine the emotional valence (positive, negative) of …


Parsing Heterogenity In Non-Episodic, Pediatric Irritability: A Transdiagnostic, Research Domain Criteria Informed Approach, Merelise Rose Ametti Jan 2019

Parsing Heterogenity In Non-Episodic, Pediatric Irritability: A Transdiagnostic, Research Domain Criteria Informed Approach, Merelise Rose Ametti

Graduate College Dissertations and Theses

Background: Approximately 7% of clinically referred youth exhibit profound impairment in the ability to regulate their affect, behavior, and cognition. This phenotype – often referred to as dysregulation – has been associated with a multitude of negative outcomes. Symptom overlap between dysregulation and other psychological disorders has generated debate regarding whether DP constitutes a distinct syndrome characterized by intense, persistent irritability or is merely the combination of symptoms from disruptive or mood disorders. In order to elucidate this question, the current study examined the transdiagnostic continuities and discontinuities in three RDoC constructs (frustrative non-reward, acute threat, and cognitive control) proposed …


Individual Differences In Relational Learning And Analogical Reasoning: A Computational Model Of Longitudinal Change, Leonidas A. A. Doumas, Robert G. Morrison, Lindsey E. Richland Jul 2018

Individual Differences In Relational Learning And Analogical Reasoning: A Computational Model Of Longitudinal Change, Leonidas A. A. Doumas, Robert G. Morrison, Lindsey E. Richland

Psychology: Faculty Publications and Other Works

Children’s cognitive control and knowledge at school entry predict growth rates in analogical reasoning skill over time; however, the mechanisms by which these factors interact and impact learning are unclear. We propose that inhibitory control (IC) is critical for developing both the relational representations necessary to reason and the ability to use these representations in complex problem solving. We evaluate this hypothesis using computational simulations in a model of analogical thinking, Discovery of Relations by Analogy/Learning and Inference with Schemas and Analogy (DORA/LISA; Doumas et al., 2008). Longitudinal data from children who solved geometric analogy problems repeatedly over 6 …


Investigating The Interaction Of Emotion And Cognition: Conflict Adaptation And The Impact Of Emotionally-Salient Distraction, Samantha Goldsmith Jun 2018

Investigating The Interaction Of Emotion And Cognition: Conflict Adaptation And The Impact Of Emotionally-Salient Distraction, Samantha Goldsmith

Electronic Thesis and Dissertation Repository

Individual differences in cognitive control have significant implications for a broad range of everyday functions, from driving a car to maintaining healthy relationships. In a world filled with salient, task-irrelevant information, it is imperative to investigate cognitive control in the context of distraction. The current study investigated the interference effect of emotional versus non-emotional distraction in a conflict adaptation paradigm. Forty-seven young adults completed several individual difference measures and an emotional flanker task. Results failed to support the hypothesis that distractor valence would interact with prior and current flanker congruency, but showed a trend toward an effect of distractor valence …


Attentional Deployment, Cognitive Control, And Reappraisal In Schizophrenia, Kyle Robert Mitchell Jun 2018

Attentional Deployment, Cognitive Control, And Reappraisal In Schizophrenia, Kyle Robert Mitchell

LSU Doctoral Dissertations

Recent studies posit that deficits in emotion regulation may lead to increased negative emotional experience in schizophrenia. While individuals with schizophrenia evidence a number of abnormalities in emotion regulation, it is unclear whether these deficits are discrete or related; furthermore, the mechanisms underlying these deficits are not clear. Cognitive control has been posited as an important mechanism supporting emotion regulation. The current study examined the relationship between attentional deployment and both lexical and self-reported indices of reappraisal, as well as the mediating role of cognitive control on this relationship in a sample of 22 individuals with psychotic disorders. A novel …


How Does Anxiety Affect Cognitive Control? Proactive And Reactive Control Under State Anxiety, Youcai Yang May 2018

How Does Anxiety Affect Cognitive Control? Proactive And Reactive Control Under State Anxiety, Youcai Yang

Theses and Dissertations

Cognitive control is a construct that prioritizes how we process stimuli and information and execute behaviors to flexibly and efficiently adapt to internal goals and external environmental changes. A recent theory, the Dual Mechanism of Control (DMC), distinguishes this phenomenon by two distinct cognitive control operations: proactive control and reactive control (Braver, 2012). Anxiety increases the allocation of attentional and working memory resources to threat-related stimuli, which impairs cognitive performance (Sarason, 1988), but additional work is needed to assess how anxiety impacts these two distinct forms of cognitive control. In this study, I examined how state anxiety affected proactive control, …

Brain and Mind Institute Researchers' Publications

© 2017 The Authors The ability to stop actions and thoughts is essential for goal-directed behaviour. Neuroimaging research has revealed that stopping actions and thoughts engage similar cortical mechanisms, including the ventro- and dorso-lateral prefrontal cortex. However, whether and how these abilities require similar subcortical mechanisms remains unexplored. Specifically of interest are the basal ganglia, subcortical structures long-known for their motor functions, but less so for their role in cognition. To investigate the potential common mechanisms in the basal ganglia underlying action and thought stopping, we conducted meta-analyses using fMRI data from the Go/No-Go, Stop-signal, and Think/No-Think tasks. All three …


Affect And Cognitive Control: The Influence Of Naturalistic Mood On Interference Processing, Lorri A. Kais Jan 2018

Affect And Cognitive Control: The Influence Of Naturalistic Mood On Interference Processing, Lorri A. Kais

Dissertations

Every day planning and execution of goal-directed human performance is dependent upon cognitive and emotional processes that are inherently interlinked. However, the effect of naturalistic mood states on cognitive control remains relatively unexamined. The present study builds upon existing literature regarding affective and executive processes by investigating the relationship between naturally occurring positive mood state and interference processing during a modified Color-Word Stroop Task (CWST). To further clarify the time course and recruitment of neural resources during different conditions of the CWST the present study utilized event-related potentials (ERPs). Incongruent stimuli were compared to congruent stimuli in blocked (same congruency) …
