A Mixed Method Investigation On The Effects Of Information And Motivation On Self-Regulation Skills And Fruit And Vegetable Consumption, Kristen Buford
A Mixed Method Investigation On The Effects Of Information And Motivation On Self-Regulation Skills And Fruit And Vegetable Consumption, Kristen Buford
Theses and Dissertations--Psychology
Introduction: The purpose of this research study is to understand the interplay between health information and health motivation on eating behaviors in African American emerging adults. Greater knowledge of nutrition is linked to healthier eating outcomes, but the motivations that individuals possess about their ability to improve their health also play a pivotal role. However, the joint effect of such constructs (i.e., information and motivation) on eating behaviors is unknown. Emerging adults are still developing their capacities to exercise their health autonomy, and this developmental period represents an opportunity to intervene before the onset of age-related chronic diseases in middle …
Brief Therapy Dog Interactions May Increase Self-Efficacy And Lower Perceived Stress And Cortisol In High School Students: A Preliminary Study, Dawn Melzer, Deirdre Yeater, Madison Derubis, Christiana Rose Kohlroser, Barbara J. Pierce
Brief Therapy Dog Interactions May Increase Self-Efficacy And Lower Perceived Stress And Cortisol In High School Students: A Preliminary Study, Dawn Melzer, Deirdre Yeater, Madison Derubis, Christiana Rose Kohlroser, Barbara J. Pierce
Psychology Faculty Publications
The present study examined changes in high schoolers’ perceived stress, general self-efficacy and cortisol levels after a brief interaction with a certified therapy dog. High school students completed self-report measures of perceived stress and general self-efficacy and provided salivary cortisol samples both before and after a 10-min interaction with a certified therapy dog. Following the interaction, students reported reductions in perceived stress scores, exhibited lower salivary cortisol concentrations and demonstrated increases in self-efficacy scores compared to before the interaction. Although higher self-efficacy scores were observed, general self-efficacy is generally regarded as a stable construct; therefore, these findings may reflect a …
Effects Of Coaching Interventions On Burnout And Mental Health Outcomes Among Collegiate Athletes: A Meta-Analysis, Natalie Mitchell
Effects Of Coaching Interventions On Burnout And Mental Health Outcomes Among Collegiate Athletes: A Meta-Analysis, Natalie Mitchell
Cal Poly Humboldt theses and projects
This meta-analysis examined the effects of coaching interventions on burnout and mental health outcomes among collegiate athletes. Following PRISMA guidelines, literature published from 1980 onward was searched across SPORTDiscus, PsycINFO, PsycARTICLES, PubMed/MEDLINE, Web of Science, and ProQuest Theses & Dissertations. Studies were included if they assessed burnout, psychological well-being, or related mental health outcomes in collegiate athletes and investigated a coaching intervention. Twelve interventional studies met the inclusion criteria. Across studies, coaching interventions varied in structure, duration, sport context, and cultural setting, with most emphasizing intrapersonal strategies and emotional or mental health outcomes. Meta-analytic results indicated small, non-significant effects favoring …
The Phenomenon Of Professional Burnout Among Military Chaplains In Ukraine, Artem Makovskyi, Oleg Mateyuk, Oleksandr Bilovskyi, Anton Datskov, Dmytro Oleshko
The Phenomenon Of Professional Burnout Among Military Chaplains In Ukraine, Artem Makovskyi, Oleg Mateyuk, Oleksandr Bilovskyi, Anton Datskov, Dmytro Oleshko
Occasional Papers on Religion in Eastern Europe
The article presents a comprehensive study of the phenomenon of professional burnout among military chaplains in Ukraine in the context of their personal experience of being in extreme (combat) conditions. The relevance of the problem is due to the prolonged impact of combat operations, high psycho-emotional stress, and the special role of military chaplains in the system of moral and psychological support for Ukraine's security and defense sector. The theoretical and methodological basis of the study was the concept of professional burnout by K. Maslach, the provisions of the person-centered approach, and the theory of personal experience. The empirical study …
The Impact Of Belonging To Identity-Based Student Organizations On Minority Stress In A Midwestern Predominantly White University, Mallory Millet, Akanksha Das, Christian C. Garcia, Rose Marie Ward
The Impact Of Belonging To Identity-Based Student Organizations On Minority Stress In A Midwestern Predominantly White University, Mallory Millet, Akanksha Das, Christian C. Garcia, Rose Marie Ward
Journal of Higher Education & Student Affairs
Minoritized students are exposed to additional unique stressors due to the systematic devaluation of their identities (i.e., minority stress). Additionally, minoritized students report higher levels of mental health concerns than their peers (e.g., anxiety, depression). Identity-based student organizations can be one avenue that universities could use to support these students. These organizations, designed to build social connections among students with shared experiences, may reduce minority stress through fostering students’ sense of belonging. However, the relationship between sense of belonging, minority stress, and identity-based student organizations has yet to be studied. The present study used quantitative and qualitative methods to understand …
Increasing The Efficiency Of Screening For Severity Level Of Neurocognitive Impairment In The Corrections Sample: An Exploratory Study, Kelly Denton
PCOM Psychology Dissertations
Acquired brain injury (ABI) is a serious and potentially devastating health condition that can cause several lasting deleterious consequences affecting many domains of life. Difficulties are commonly reported in cognition, emotional, and social functioning, in addition to physical impairment. ABI disproportionally affects different groups, including the corrections population, which is five times more likely than the general population to have an ABI. However, there is limited research on the severity of neurocognitive impairment after an ABI for inmates in a correctional setting. It was hoped that the current study would help clarify the characteristics of ABI that result in different …
The Influence Of Parental Attitudes On Perceptions Of Gender Socialization In Their Children, Tareva Cortes
The Influence Of Parental Attitudes On Perceptions Of Gender Socialization In Their Children, Tareva Cortes
PCOM Psychology Dissertations
Gender socialization begins early in childhood and plays a significant role in shaping children's beliefs, behaviors, and perceptions of themselves and others. Parents serve as primary agents of gender socialization and contribute to children's understanding of gender roles through attitudes, expectations, and reinforcement of gender-related behaviors. The purpose of this quantitative study was to examine parental attitudes regarding traditional gender roles, modern sexism, and children's gender-related behaviors. Participants included 163 parents and legal guardians residing in the United States who had at least one child under the age of 18. Participants completed a demographic questionnaire, the Child Gender Socialization Scale, …
Improving Parental Self-Efficacy In An Integrated Primary Care Setting, Leo Parini
Improving Parental Self-Efficacy In An Integrated Primary Care Setting, Leo Parini
Antioch University Dissertations & Theses
A pediatric mental health crisis in the United States has strained integrated primary care, leaving providers with high volumes of requests for psychotherapy. Low parental self-efficacy (PSE)—reduced caregiver confidence in supporting children's emotional and behavioral needs—may contribute to this demand. This study examined whether a brief, 4-week parent training curriculum informed by Supportive Parenting for Anxious Childhood Emotions (SPACE), targeting child anxiety and obsessive-compulsive disorder (OCD) and delivered by a clinical psychologist within an integrated primary care setting, would increase PSE. Using secondary, de-identified data, PSE was measured before and after the course with the Brief Parental Self-Efficacy Scale; 19 …
Modeling Hazard Perception Learning In Novice Drivers With Autism: A Multimodal Simulation-Based Study, Erik J. Sand
Modeling Hazard Perception Learning In Novice Drivers With Autism: A Multimodal Simulation-Based Study, Erik J. Sand
Graduate Studies Theses and Dissertations 2026
Young drivers with autism spectrum disorder (ASD) often demonstrate difficulties with road-surveillance behaviors such as scanning ahead, monitoring mirrors, and identifying emerging hazards. These challenges can increase crash risk, particularly for adolescents with limited driving experience. This study explored whether a simple, video-game–based hazard-training program could improve hazard detection performance, visual scanning, and self-regulation in this population. Five participants aged 15–18 years, each identified by a parent as having ASD and possessing either a learner’s permit or no license, completed sequential Baseline, three Treatment, and Withdrawal phases using the SpeedLimit driving simulation. The study employed a single-case experimental design with …
The Silent Language Of Trauma: Defendant Behavior, Juror Bias, And Expert Testimony, Jensen Goldman
The Silent Language Of Trauma: Defendant Behavior, Juror Bias, And Expert Testimony, Jensen Goldman
Scripps Senior Theses
Trauma can profoundly influence behavioral presentation, yet jurors often rely on demeanor as a diagnostic cue for guilt, credibility, and remorse. Such reliance poses risks within a legal system that seldom equips jurors to interpret trauma related behaviors accurately. The proposed study will examine how two trauma-linked affective presentations– overemotionality and flat affect– shape juror perceptions of credibility and guilt, and whether expert psychological testimony about trauma-related affect can mitigate these biases. Online survey participants will read one of five trial vignettes with varying defendant conditions (flat affect vs. overemotional) and varying expert testimony conditions (present or not present) and …
Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb
Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb
Psychology Faculty Publications
Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …
Social Exclusion, Social Support, And Trauma, Eric D. Wesselmann
Social Exclusion, Social Support, And Trauma, Eric D. Wesselmann
Faculty Publications – Psychology
Humans have an inherent need to forge stable and quality social connections. One key benefit of having social connections is obtaining social support for navigating traumatic or otherwise stressful events. Ostracism (i.e. being both ignored and excluded, Williams, 2009) and other forms of social exclusion rob individuals of the opportunity to receive social support and likely contribute to stress-related mental health concerns. My colleagues and I tested this premise in different stress-related contexts, ranging from college students struggling with potentially stigmatizing secrets to community members who have experienced various types of traumatic incidents (e.g., miscarriage, military combat). We examined the …
Righteous Defenders And Evil Challengers: The Morally Polarized Battle For Books On Reddit, Erika Casburn
Righteous Defenders And Evil Challengers: The Morally Polarized Battle For Books On Reddit, Erika Casburn
Antioch University Dissertations & Theses
The issue of book bans has moved to the forefront of public and political debate over the past few years. Anti-censorship advocates who defend against these challenges have yet to be studied. The purpose of this study was to examine the beliefs and worldviews as expressed by those defenders in a public forum—Reddit. Data in the form of Reddit threads was collected from subreddits belonging to states that have seen the greatest number of book challenges. This data was subjected to discourse analysis, first manually, then by qualitative analysis software (MAXQDA). Analysis revealed that defenders spent a majority of discursive …
The Impact Of The Covid-19 School Shutdown On Standardized Test Scores In Rural And Nonrural Areas, Cory Laflamme
The Impact Of The Covid-19 School Shutdown On Standardized Test Scores In Rural And Nonrural Areas, Cory Laflamme
Antioch University Dissertations & Theses
The novel Coronavirus of 2019 (COVID-19; Gillings School of Global Public Health, n.d.) caused an extensive disruption of education systems worldwide. Elementary and secondary schools began to close to students and staff to protect them from potential exposure to the virus (Masonbrink & Hurley, 2020). Nearly 1.6 billion students in over 200 countries had their learning impacted on some level, causing changes in traditional educational practices (Pokhrel & Chhetri, 2021). One profound change in educational practice was the shift from face-to-face learning to online learning alternatives. Using the State of New Hampshire data allowed for a unique analysis of how …
The Effect Of Paternal Engagement On The Sexual Self-Concept Of Black Female Adolescents, Amelia Flynn
The Effect Of Paternal Engagement On The Sexual Self-Concept Of Black Female Adolescents, Amelia Flynn
Antioch University Dissertations & Theses
Black women in the U.S. continue to experience disproportionately high rates of unintended pregnancies, with a 64% rate reported in 2011 (Finer & Zolna, 2016). Positive sexual self-concept (SSC) is linked to healthier sexual behaviors, yet research on SSC development has largely overlooked the role of fathers and systemic influences, particularly within Black families. Grounded in an ecological framework, this study examines the impact of father-daughter engagement on SSC among Black female adolescents, considering paternal residential status and socioeconomic class as key contextual factors. The study revealed that when middle class father-daughter engagement is high, daughters’ sexual self-esteem is lower. …
Storytelling And Equity: A Program Evaluation That Promotes And Supports Narrative-Based Learning And Open Dialogue Practices At Higher Ed Institutions, Regis A. Peeples
Storytelling And Equity: A Program Evaluation That Promotes And Supports Narrative-Based Learning And Open Dialogue Practices At Higher Ed Institutions, Regis A. Peeples
Antioch University Dissertations & Theses
On college campuses worldwide, storytelling functions as a primary method for transmitting and affirming knowledge. It serves to validate lived experiences, acts as a relational teaching tool, and supports theoretical inquiry. Given that teaching is inherently political, storytelling can also perpetuate hate, oppression, and other social harms within academic environments. Even when educators use storytelling constructively, limited training exists on the full range of its impacts on students, particularly in terms of what may be described as “dangerous” storytelling. Dangerous storytelling refers to narratives, intentional or authentic, that reinforce or cultivate phobias about physical appearance (e.g., race, culture, nationality), propagate …
Hiding In Plain Sight, Gayle M. Perreault
Hiding In Plain Sight, Gayle M. Perreault
Antioch University Dissertations & Theses
Some autistic individuals reach adulthood without receiving a diagnosis, and the processes contributing to delayed recognition are not yet fully understood. This study explored how contextual conditions across development related to the emergence and use of camouflaging behaviors in late-diagnosed autistic adults from groups historically underrepresented in autism research. Using an inductive collective case study design, narrative interviews were conducted with seven autistic adults diagnosed after age 15. The analysis examined how participants described learning, maintaining, and interpreting camouflaging behaviors across childhood through early adulthood within social, environmental, and institutional contexts, with attention to how participants experienced environmental expectations and …
Illuminating Secrets Of Harmful Supervision: A Narrative Inquiry Into The Lived Experiences Of Marriage And Family Therapy Supervisees Of Color During Clinical Supervision And The Effects On Their Personal And Professional Identity, Danielle Garcia Gomez
Antioch University Dissertations & Theses
Harmful supervision is a critical yet often underexamined issue for supervisees of color (SOC), whose lived experiences are underrepresented in clinical supervision literature. Given the hierarchical and evaluative nature of clinical supervision, power dynamics are placed at the center of professional training, thereby creating conditions where unchecked supervisory power can lead to harm. Within Marriage and Family Therapy (MFT), research on harmful supervision is limited, despite the profession’s emphasis on relational dynamics. This qualitative study aimed to amplify the voices of SOC victim-survivors of harmful supervision and to answer the research question: How have harmful supervision experiences affected the personal …
Mental Health Therapists’ Experiences Of Moral Injury, Mary Krome
Mental Health Therapists’ Experiences Of Moral Injury, Mary Krome
Antioch University Dissertations & Theses
Moral injury refers to the psychological, social, behavioral, and spiritual consequences that may result from experiences involving perceived violations of deeply held moral values and beliefs. Although research on moral injury has expanded beyond military populations, limited attention has been given to the experiences of mental health therapists, and qualitative investigations of this phenomenon remain scarce. Therefore, this project provides a qualitative assessment of mental health therapists’ lived experiences of moral injury, using an ecosystemic approach and accounting for biopsychosocial factors that influence experiences of moral injury. Six mental health therapists completed the Moral Injury and Distress Scale and endorsed …
Into Action: A Twelve Step-Informed Act Group Protocol For Outpatient Substance Use Treatment, Doug Hohenberger
Into Action: A Twelve Step-Informed Act Group Protocol For Outpatient Substance Use Treatment, Doug Hohenberger
Antioch University Dissertations & Theses
Substance use disorders remain a prevalent and costly public health concern. Despite this, efforts to disseminate evidence-based practices frequently encounter both practical and philosophical barriers. Language and practices from the Twelve Steps of Alcoholics Anonymous have permeated addiction treatment settings and have become the “common tongue” for addiction recovery discourse. Consequently, most substance use treatment programs feature tenets of the Twelve Steps of Alcoholics Anonymous in their clinical programming, even though the framework was designed for peer support settings. Twelve Step fellowships have made important contributions to the substance use treatment field and have guided individuals through personal recovery through …
Adverse Childhood Experiences Of Individuals Charged Or Convicted Of Homicide In Their Youth, Marcus Krodel
Adverse Childhood Experiences Of Individuals Charged Or Convicted Of Homicide In Their Youth, Marcus Krodel
Antioch University Dissertations & Theses
Adverse Childhood Experiences (ACEs) represent a collection of distressful events occurring during childhood and have been shown to have a negative impact on future functioning. ACEs were utilized in the current study to increase our understanding of a unique population among court-involved individuals: juveniles charged or convicted of homicide. Court decisions have established that juveniles convicted of homicide are both distinct from their adult counterparts and present with dissimilar risk and protective factors. The current study explored a sample of 66 individuals who were charged or convicted of homicide while in their youth. Each participant was retroactively assigned an ACEs …
Cross-Domain Identity Development In Bipoc Autistic Adults: A Grounded Theory Study, Ginnylyne Mariano Guisadio
Cross-Domain Identity Development In Bipoc Autistic Adults: A Grounded Theory Study, Ginnylyne Mariano Guisadio
Antioch University Dissertations & Theses
Racial and autistic identity development both involve navigating stigma, seeking community, and contending with dominant frameworks that constrain authentic self-expression, yet existing research has not examined how these processes interact for individuals holding both identities. These interactions unfold within structural conditions such as diagnostic disparities, culturally specific ableism, and racialized consequences of visible autistic expression, which shape how identity development proceeds for BIPOC autistic adults. This study investigated whether and how the core identity processes of exploration and commitment proceeded for this population. Nine BIPOC autistic adults participated in written interviews analyzed through constructivist grounded theory, with identity status theory …
Dancing With The Void: A Cultural Exploration Of Nihilistic Musical Identities And Their Experience In Psychotherapy, Zachary Marciano
Dancing With The Void: A Cultural Exploration Of Nihilistic Musical Identities And Their Experience In Psychotherapy, Zachary Marciano
Antioch University Dissertations & Theses
This dissertation examines the profound existential paradox faced by individuals who have identified with nihilistic beliefs and ideas while attempting to seek meaning through therapy. Nihilism, characterized by the belief in the inherent meaninglessness of existence, poses a significant challenge to the traditional therapeutic framework, which often centers on the pursuit of meaning and purpose. This dichotomy poses a unique conundrum for individuals who embrace nihilistic perspectives shaped by identification with nihilistic lyrics and themes in alternative music genres such as metal, goth, grunge, and punk. Alternative music culture often serves as a vehicle for expressing and internalizing nihilistic beliefs, …
Parent Perspectives: Child Attendance In Community Grief Support, Janeene Sanderson
Parent Perspectives: Child Attendance In Community Grief Support, Janeene Sanderson
EWU Masters Thesis Collection
Childhood bereavement can affect children emotionally, socially, and developmentally, creating a need for support that is both age-appropriate and grief-informed. This qualitative study explored how parents perceived the impact of community grief support programs for their bereaved children. The study focused on children ages 8–12 who attended a peer support group, grief camp, or similar community-based grief support program after the death of a loved one. Data were collected through parent interviews and reviewed through thematic analysis. Findings showed that parents perceived these programs as meaningful because they created safe spaces where children could feel normal and validated in their …
The Impact Of Flight Instructor Feedback On Subsequent Instructor Evaluations Of Student Performance, Ayhan Rozyyev, Jennifer E. Thropp
The Impact Of Flight Instructor Feedback On Subsequent Instructor Evaluations Of Student Performance, Ayhan Rozyyev, Jennifer E. Thropp
Journal of Aviation/Aerospace Education & Research
This study examines the impact of feedback tone and feedback order on flight instructors’ evaluations of student performance in an aviation training context. Using a 2×2 mixed factorial design, 40 certified flight instructors reviewed fictitious training records and rated students based on feedback that varied in tone (positive vs. negative) and order (positive-first vs. negative-first). Results showed that positive feedback significantly influenced evaluations across all measured dimensions, while feedback order had no significant effect, challenging assumptions about primacy and recency effects. These findings highlight the role of positive reinforcement in shaping instructor evaluations and suggest that structured training environments can …
Impact Of In-Cabin Human Machine Interface Designs On Passenger Trust In Urban Air Mobility, Ricole A. Johnson, Erika E. Gallegos
Impact Of In-Cabin Human Machine Interface Designs On Passenger Trust In Urban Air Mobility, Ricole A. Johnson, Erika E. Gallegos
Journal of Aviation/Aerospace Education & Research
Urban Air Mobility (UAM) presents a promising solution for alleviating urban traffic congestion and enhancing transportation efficiency. However, the widespread acceptance of UAM, particularly sustained ridership of autonomous passenger air vehicles (PAVs), is contingent upon addressing critical human factors for building passenger trust, especially in the absence of a human pilot. This paper evaluates how different in-cabin human-machine interface (HMI) designs affect passenger trust in the aircraft and in-cabin display, situation awareness, and pilot preferences. Forty participants, equally split between early and late technology adopters, completed two simulated flights: a baseline flight with no HMI and a second flight featuring …
Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.
Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.
Theses and Dissertations (Comprehensive)
Cognition is widely believed to be adaptive, yet few studies directly show that variation in cognitive performance is related to fitness. Brown-headed cowbirds (Molothrus ater) provide a powerful system for addressing this gap because brood parasitism creates strikingly different reproductive problems for females and males. Females face the spatial demands of nest-prospecting, whereas males face social and competitive demands associated with access to mates. Across five experiments, cowbirds were tested on an outdoor foraging task designed as an analogue of nest prospecting, with manipulations of retention interval, cue conflict, and breeding condition, followed by observations of reproductive behaviour. …
Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch
Mixed Methods Insights Into Understandings Of And Stigma Towards Autism In Children And Young Adults, Natalia Gc Van Esch
Theses and Dissertations (Comprehensive)
BACKGROUND: Autism is widely stigmatized and misunderstood. Existing research using methods such as questionnaires finds that autistic individuals are often evaluated more negatively than their non-autistic counterparts. Unfortunately, this approach provides limited insight into the underlying representations of autism that individuals hold. The present study seeks to examine how children and adults define, describe, and represent autism, and how these representations relate to stigma. METHODS: In Part I, children participated in a semi-structured interview in which they defined autism and created autistic and non-autistic characters using a guided character-building task. Children then rated their characters on a series of social …
Exploring The Role Of Cognitive Load In Applicant Faking And Prevention Methods, Sabah Rasheed
Exploring The Role Of Cognitive Load In Applicant Faking And Prevention Methods, Sabah Rasheed
Theses and Dissertations (Comprehensive)
Personnel selection is critical to organizational success, and personality assessment is widely used to identify the best job candidates. However, applicant faking threatens the validity of personality assessments in high-stakes contexts. Faking is widely assumed to be more cognitively demanding than honest responding, and several faking-prevention methods rest on this premise. This dissertation examines that assumption across three studies using the dual-task paradigm to impose cognitive demands during personality assessments. Study 1 used a verbal digit-span task with a student sample and limited faking on the three job-relevant personality composites. Study 2 used a visual dual-task with a student sample …
Neural Correlates Of Cognitive Fatigue In Regular Cannabis Users And Non-Users: A Pilot Fnirs Study, Mariia Vistyzenko
Neural Correlates Of Cognitive Fatigue In Regular Cannabis Users And Non-Users: A Pilot Fnirs Study, Mariia Vistyzenko
Theses and Dissertations (Comprehensive)
Background: Cognitive fatigue impairs performance across multiple domains, yet how regular cannabis use affects fatigue responses remains unclear. This pilot study investigated neural and behavioural correlates of cognitive fatigue in abstinent cannabis users versus non-users.
Methods: Twenty-six participants (18 non-users, 8 regular cannabis users after 24-hour abstinence) completed cognitive tasks before and after a 60-minute Sustained Attention to Response Task (SART) designed to induce fatigue. Tasks assessed working memory (N-Back), cognitive flexibility (Wisconsin Card Sorting), psychomotor speed (Digit Symbol Substitution), sustained attention (Continuous Performance Task), inhibition (Stroop, Stop Signal), and motion perception. Functional near-infrared spectroscopy (fNIRS) continuously monitored prefrontal cortex …
