A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal

Journal of Human Performance in Extreme Environments

In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

The Effect That Testing Has On Nondeclarative Memory, David Smith

Electronic Theses and Dissertations

Testing has been shown to improve long-term memory retention by decreasing the amount of material forgotten, a phenomenon known as the testing effect. This positive impact of testing has been shown using direct tests of memory that require declarative memory, things like memorizing word-pairs and single-word lists. This dissertation is the first research to investigate how testing impacts nondeclarative memory using three experiments. The first and second experiment utilize the word fragment completion task to measure the effect that testing has on words learned via methodology thought to recruit either declarative or nondeclarative memory. The third experiment utilizes a probabilistic …

Outdoor Air Pollution Exposure And Inter-Relation Of Global Cognitive Performance And Emotional Distress In Older Women, Andrew J. Petkus, Xinhui Wang, Daniel P. Beavers, Helena C. Chui, Mark A. Espeland, Margaret Gatz, Tara Gruenewald, Joel D. Kaufman, Joann E. Manson, Susan M. Resnick, James D. Stewart, Gregory A. Wellenius, Eric A. Whitsel, Keith Widaman, Diana Younan, Jiu-Chiuan Chen

Psychology Faculty Articles and Research

The interrelationships among long-term ambient air pollution exposure, emotional distress and cognitive decline in older adulthood remain unclear. Long-term exposure may impact cognitive performance and subsequently impact emotional health. Conversely, exposure may initially be associated with emotional distress followed by declines in cognitive performance. Here we tested the inter-relationship between global cognitive ability, emotional distress, and exposure to PM2.5 (particulate matter with aerodynamic diameter 2 (nitrogen dioxide) in 6118 older women (aged 70.6 ± 3.8 years) from the Women’s Health Initiative Memory Study. Annual exposure to PM_2.5 (interquartile range [IQR] = 3.37 μg/m³) and NO₂ (IQR …

Modulation Of P3 And The Late Positive Potential Erp Components By Standard Stimulus Restorativeness And Naturalness, Salif P. Mahamane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tests of attention restoration theory (ART) consistently support that exposure to restorative environments can replenish finite cognitive resources, needed to focus attention, from a depleted state. These environments are usually natural, but the dimensions of naturalness and restorativeness are not one and the same, and yet have not been empirically delineated. The restorative effect has been documented in children and adults. However, neuroscientists have barely begun to test for neural correlates of ART. In this dissertation, I employ electroencephalography (EEG) to record electrophysiological brain activity during an active visual oddball task to capture and analyze p3 elicitation and late positive …

Is Executive Function The Universal Acid?, Stephen J. Morse

All Faculty Scholarship

This essay responds to Hirstein, Sifferd and Fagan’s book, Responsible Brains (MIT Press, 2018), which claims that executive function is the guiding mechanism that supports both responsible agency and the necessity for some excuses. In contrast, I suggest that executive function is not the universal acid and the neuroscience at present contributes almost nothing to the necessary psychological level of explanation and analysis. To the extent neuroscience can be useful, it is virtually entirely dependent on well-validated psychology to correlate with the neuroscientific variables under investigation. The essay considers what executive function is and what the neuroscience adds to our …

A Whiteheadian Innervation Of The Soma: A New Vision For The Peripheral Nervous System, David Milliern

Journal of Conscious Evolution

This essay draws attention to two problems in neuroscience’s set of assumptions. These self-defeating assumptions include: 1) the assumption that what the nervous system, especially the brain, does is synthesize experience, while also assuming philosophical realism, and 2) the problem of biological signal transduction. In the latter, neuroscientists and philosophers of biology have left unaddressed the issue that the signal differences between the inside and outside of the organismic boundary are of distinct ontological types; and yet no concern has been expressed regarding how it is possible that an organism’s inner states could reflect the experiential content flowing from outside …

S3e6: How Do Face Masks Affect First Impressions?, Ron Lisnet, Mollie Ruben

The Maine Question

There’s an adage that people don’t get a second chance to make a first impression. Mollie Ruben, assistant professor of psychology, examines how face masks affect people’s first impressions of others during the COVID-19 outbreak. Do people appear more or less smart to others, depending on whether they’re wearing or not wearing a mask? More or less friendly? Learn about this research project conducted by Ruben, who directs the Emotion, Pain, and Interpersonal Communication (EPIC) Lab at the University of Maine.

Memory Bias Toward Emotional Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Lucas M. Bietti, Eric Mayor

Publications and Research

A sample of 1015 educational staff members, exhibiting various levels of burnout and depressive symptoms, underwent a memory test involving incident encoding of positive and negative words and a free recall task. Burnout and depression were each found to be associated with increased recall of negative items and decreased recall of positive items. Results remained statistically significant when controlling for history of depressive disorders. Burnout and depression were not related to mistakes in the reported words, or to the overall number of recalled words. This study suggests that burnout and depression overlap in terms of memory biases toward emotional information.

Affective, Physiological, And Cognitive Response To Imagery- And Verbally-Based Rumination And Distraction In Adolescence, Hannah Lawrence

Electronic Theses and Dissertations

To date, rumination and interventions for rumination have largely been verbal in focus. Rumination has been conceptualized as dwelling on negative affect in the form of verbal thought, and interventions aim to interrupt cycles of rumination using verbal strategies. Yet, emerging evidence suggests that many individuals dwell on negative affect in the form of imagery (e.g., Lawrence, Haigh, Siegle, & Schwartz-Mette, 2018) and that imagery-based interventions may be even more effective (e.g., Arntz, 2012). This is not surprising as imagery is more affectively arousing (Holmes & Mathews, 2010), physiologically stimulating (Vrana, Cuthbert, & Lang, 1986), and realistic/vivid (Mathews, Ridgeway, & …

The Role Of Information Search In Creative Problem Solving, Mackenzie Harms, Roni Reiter-Palmon, Douglas C. Derrick

Psychology Faculty Publications

This study investigates the role that information search behavior plays in the process of creative problem solving. Although models of creative processing posit that information search is a necessary stage of creative problem solving, no research has separated and measured information search from earlier processes to determine the nature of the role it plays in the creative problem solving process. Two hundred twenty-one people participated in a study where active engagement in problem construction was manipulated. Participants were allowed to search for additional information that may facilitate the generation of a creative solution. Measures of information search that have been …

Microdosing Mindfulness: Understanding The Effects Of Brief Mindfulness Meditation In Children With Adhd, Marcus D. Gottlieb

Electronic Thesis and Dissertation Repository

Mindfulness Meditation (MM) is receiving increased empirical support as a method for addressing ADHD symptomology. Research shows that MM interventions lasting weeks or months promote key aspects of cognitive and psycho-emotional functioning in youth with ADHD. Using a pre-post within-subjects design, we sought to determine whether a single MM session supports neurocognitive and/or psycho-emotional functioning in youth with ADHD. Sixteen participants aged 10-14 completed measures of executive and psycho-emotional functioning before/after a 10-minute MM session and silent reading control. Functional neuroimaging assessed whether MM supported changes in prefrontal cortex (PFC) activation during cognitive tasks. We found that a single MM …

Depression, Music Choice, And Affective Outcomes In Daily Life, Sunkyung Yoon

USF Tampa Graduate Theses and Dissertations

Persons with depression consistently report a preference for sad music. Are such preferences maladaptive or beneficial? We tested this question in a 3-part study that examined 77 participants’ (39 with and 38 without clinical depression) music choice in daily life, affective outcomes, and the reasons for music choice. During a 3-day ecological momentary assessment (EMA), participants chose a song from a pre-set music library of happy and sad songs and rated their affect before and after hearing the chosen song. In addition, we analyzed the characteristics (e.g., tempo) of participants’ free song choices over 7 days (from participants’ Spotfiy music …

The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago

Dissertations

Aging is an inevitable process, accompanied by changes in physiological, cognitive, psychological, and social facets. Researchers have investigated the physiological, cognitive, psychological, and social risk factors associated with aging and have encouraged the use of physical activity, cognitive training, and dietary interventions to alleviate risk factors. However, holistic programs dedicated to promoting successful aging among older adults are uncommon. This review sought to promote successful aging by identifying physiological, cognitive, psychological, and social risk factors that affect older adults and develop a comprehensive program to holistically mitigate these risk factors. Risk factors associated with unsuccessful aging include the development of …

Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson

Honors Theses

Background: Our recent experimental work demonstrated that high-intensity acute exercise improved veridical (true) memories and also increased the rate of false memories. The present experiment was designed to re-evaluate these effects for replication purposes. We also extend this literature by evaluating whether these effects are influenced by the timing of acute exercise. Methods: The sample included young adults (N=37; M_age = 21.16 years). We employed a three-condition, within-group, counterbalanced controlled design, consisting of two exercise conditions and a control condition. The exercise conditions involved a 15-minute bout of high-intensity acute exercise. These conditions included the bout of …

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey

Psychology and Counseling Theses

Off-topic verbosity (OTV) is tangential discourse with excessive and irrelevant information. Older adults have been historically labeled as having high OTV, and research has suggested that high OTV in older adults may be linked with cognitive decline. While past studies have utilized brief cognitive measures to further expound upon the links between cognition and OTV, studies have lacked consistency and lengthy measures. This study sought to elucidate the relationship between OTV and cognition in both older adult and young adult age cohorts utilizing a sustained attention measure. Young adults (n = 61; age range: 18-28, M = 20.57, SD = …

Evaluating The Construct Validity Of The Peak Comprehensive Assessment: Measuring Language And Cognition, Nicole Rae Mcdonald

MSU Graduate Theses

The purpose of the current study was to conduct a pilot investigation of the internal construct validity of the four modules of the PEAK Comprehensive Assessment (PCA). The PCA has been developed through robust research over the past five years (Dixon et al. 2017) and is designed to evaluate language and cognitive skills of individuals with developmental disabilities, including neurodevelopmental disorders such as Autism Spectrum Disorder. Although the PCA contains four modules exemplifying four distinct learning processes (Direct Training, Generalization, Equivalence, and Relational Learning), these four processes may represent one singular learning construct, described loosely as “executive functioning” or “cognitive …

The Effects Of Verbalizable Features On Category Learning Strategies, Marwan A. Syed

Undergraduate Honors Theses

The present study investigated the effects of how verbalizable features (easy vs not-easily) are on category learning strategies with respect to the COVIS model, which states there are two competing systems (verbal and implicit) that operate simultaneously when making categorization decisions. A total of 102 undergraduate students took part in the experiment, which was an A-B categorization task conducted in a video game setting. A rule-based approach reflected the verbal system whereas a family resemblance approach reflected the implicit system. The findings partially support the hypothesis and COVIS model in that participants in the easily verbalizable condition were more likely …

Preliminary Psychometrics For The Executive Function Challenge Task: A Novel, “Hot” Flexibility, And Planning Task For Youth, Lauren Kenworthy, Andrew Freeman, Allison Ratto, Katerina Dudley, Kelly K. Powell, Cara E. Pugliese, John F. Strang, Alyssa Verbalis, Laura G. Anthony

Psychology Faculty Research

Objective: Executive functions (EF) drive health and educational outcomes and therefore are increasingly common treatment targets. Most treatment trials rely on questionnaires to capture meaningful change because ecologically valid, pediatric performance-based EF tasks are lacking. The Executive Function Challenge Task (EFCT) is a standardized, treatment-sensitive, objective measure which assesses flexibility and planning in the context of provocative social interactions, making it a “hot” EF task. Method: We investigate the structure, reliability, and validity of the EFCT in youth with autism (Autism Spectrum Disorder; n = 129), or attention deficit hyperactivity disorder with flexibility problems (n = 93), and typically developing …

The Project Talent Twin And Sibling Study: Zygosity And New Data Collection, Carol A. Prescott, Ellen E. Walters, Thalida Em Arpawong, Catalina Zavala, Tara L. Gruenewald, Margaret Gatz

Psychology Faculty Articles and Research

The Project Talent Twin and Sibling (PTTS) study includes 4481 multiples and their 522 nontwin siblings from 2233 families. The sample was drawn from Project Talent, a U.S. national longitudinal study of 377,000 individuals born 1942–1946, first assessed in 1960 and representative of U.S. students in secondary school (Grades 9–12). In addition to the twins and triplets, the 1960 dataset includes 84,000 siblings from 40,000 other families. This design is both genetically informative and unique in facilitating separation of the ‘common’ environment into three sources of variation: shared by all siblings within a family, specific to twin-pairs, and associated with …

Social Learning In Solitary Juvenile Sharks, Catarina Vila Pouca, Dennis Heinrich, Charlie Huveneers, Culum Brown

Social Behavior Collection

Social learning can be a shortcut for acquiring locally adaptive information. Animals that live in social groups have better access to social information, but gregarious and nonsocial species are also frequently exposed to social cues. Thus, social learning might simply reflect an animal's general ability to learn rather than an adaptation to social living. Here, we investigated social learning and the effect of frequency of social exposure in nonsocial, juvenile Port Jackson sharks, Heterodontus portusjacksoni. We compared (1) Individual Learners, (2) Sham-Observers, paired with a naïve shark, and (3) Observers, paired with a trained demonstrator, in a novel foraging task. …

Neuroprotective Effects Of Cardiorespiratory Fitness On White Matter Integrity And Cognition Across The Adult Lifespan, Ryan A. Mace

Psychology Department Dissertations

Objective: Cardiorespiratory fitness (CRF) is associated with decreased risk for cognitive decline. Accumulating evidence has linked CRF to more conserved white matter (WM) integrity and better cognitive performance in older adults. Additional research is needed to determine: (1) which WM tracts are most strongly related to CRF, (2) whether CRF-related benefits on WM translate to enhanced executive functioning (EF), and (3) if the neuroprotective effects of CRF are age-dependent. This study aimed to evaluate CRF as an intervention for modulating decreased WM integrity and EF in aging. Method: Participants were community-dwelling adults (N = 499; ages 20-85) from the open-access …

No Room For Speciesism In Welfare Considerations, Jennifer Vonk

Animal Sentience

Speciesism should play no role in determining welfare outcomes. Cognition may vary within species as well as between species, but broad classifications such as invertebrates are functionally meaningless in this context. Cognition should relate to welfare only to the extent that it relates to the capacity to suffer or to experience pleasure.

Effects Of Death Anxiety On Learning Performance, Umaima Haseeb

Honors Undergraduate Theses

The present study examines whether or not a person's anxiety level might be linked to their learning performance. Many studies in the past have examined math and test anxiety, but the present study will examine the effects of death anxiety on learning performance. Individual's anxiety will attempt to be induced through fear of death. Participants were presented a set of four symptoms, similar to Gluck and Bower's 1988 category learning study. The participants were asked whether or not they think the symptoms of the patient are positive for COVID-19 or positive for the flu. The hypothesis was that there would …

An Ecological Momentary Assessment Of Self-Improved And Self-Evaluation Body Comparisons: Associations With College Women's Body Dissatisfaction And Exercise, Rachel I. Macintyre, Kristin E. Heron, Abby L. Braitman, Danielle Arigo

Psychology Faculty Publications

Upward body comparisons are prevalent among college women and associated with body dissatisfaction and disordered eating. However, less is known about distinguishing features of the comparisons themselves as they occur in daily life. The primary purpose of the present study was to examine whether two types of upward body comparisons previously studied experimentally (self-improvement and self-evaluation) are differentially associated with body- and exercise-related outcomes in real-life settings using ecological momentary assessment (EMA). Undergraduate women (N = 74) between 18-25 years (Mage = 20.4, SD = 1.63) completed five surveys on smartphones daily for seven days. EMA measures …

A Novel Approach To Measure Executive Functions In Students: An Evaluation Of Two Child-Friendly Apps, Valeska Berg, Shane Rogers, Mark Mcmahon, Michael Garrett, Dominic Manley

Research outputs 2014 to 2021

Interest in measurement of children’s executive functions has shown a major increase over the past two decades. The present study evaluates two new apps (EYT and eFun) for measuring executive functions in children. The results of this study show that children (aged 5–8) enjoy executive function assessment in the form of games on an iPad. However, only one executive function, EYT working memory, showed significant positive correlations with several types of grades (e.g., English and maths) in primary school students. New, self-assessed, child-friendly executive function measurement tools have the potential to provide future possibilities for teachers to integrate information on …

The Stained Glass Of Knowledge: On Understanding Novice Mental Models Of Computing, Briana Christina Bettin

Dissertations, Master's Theses and Master's Reports

Learning to program can be a novel experience. The rigidity of programming can be at odds with beginning programmer's existing perceptions, and the concepts can feel entirely unfamiliar. These observations motivated this research, which explores two major questions: What factors influence how novices learn programming? and How can analogy by more appropriately leveraged in programming education?

This dissertation investigates the factors influencing novice programming through multiple methods. The CS1 classroom is observed as a "whole system", with consideration to the factors present in it that can influence the learning process. Learning's cognitive processes are elaborated to ground exploration into specifically …

Depression is an unfortunately common mental illness that can lead to negative life outcomes such as substance abuse, suicide, lower quality of life, and anxiety. The stage of adolescence is known as a pivotal, transitional time of life as there are many changes in an individual’s physical, cognitive, emotional, and social development. The research reviewed throughout this paper discusses risk factors that contribute to the development of depressive symptoms in adolescence. Observing how genetic, physiological, environmental, and social components contribute to …

Integrated Care For Older Adults And Memory: A Quality Improvement Approach, Haley E. Curt

Antioch University Dissertations & Theses

Integrated care, a combination of medical and behavioral health, is necessary to address the complex needs of the rapidly growing population of adults over the age of 65 (Karel, Gratz, & Smyer, 2012). Cognitive impairment, a common issue associated with aging, is a major concern for aging adults, their caregivers and family members. Comprehensively addressing cognition, whether there is an identified impairment or not, in a primary care setting allows the individual to take advantage of their independence, be an active member of planning care and making decisions, and begin treating their disease earlier when it is more manageable (Callahan …

A Review Of Minority Stress As A Risk Factor For Cognitive Decline In Lesbian, Gay, Bisexual, And Transgender (Lgbt) Elders, Anthony N. Correro, Kristy A. Nielson

Psychology Faculty Research and Publications

Lesbian, gay, bisexual, and transgender (LGBT) older adults comprise a unique and growing subset of the aging population. The historical context in which they came of age was imbued with victimization and discrimination. These experiences are subjectively stressful and collectively known as minority stress. Older LGBT adults continue to face stressors related to their gender and sexual identities in their daily lives. Importantly, chronic minority stress (CMS), like other forms of chronic stress, is harmful to health and well-being. CMS contributes to LGBT health disparities, including cardiovascular disease and depression, conditions that in turn increase risk for premature cognitive decline. …
