Linguistic Variation From Cognitive Variability: The Case Of English 'Have', Muye Zhang Dec 2021

Linguistic Variation From Cognitive Variability: The Case Of English 'Have', Muye Zhang

Linguistics Graduate Dissertations

In this dissertation, I seek to construct a model of meaning variation built upon variability in linguistic structure, conceptual structure, and cognitive makeup, and in doing so, exemplify an approach to studying meaning that is both linguistically principled and neuropsychologically grounded. As my test case, I make use of the English lexical item ‘have' by proposing a novel analysis of its meaning based on its well-described variability in English and its embed- ding into crosslinguistically consistent patterns of variation and change.

I support this analysis by investigating its real-time comprehension patterns through behavioral, electropsychophysiological, and hemodynamic brain data, thereby incorporating …

Affective Computing For Late-Life Mood And Cognitive Disorders, Erin Smith, Eric A. Storch, Ipsit Vahia, Stephen T.C. Wong, Helen Lavretsky, Jeffrey L. Cummings, Harris A. Eyre

Brain Health Faculty Publications

Affective computing (also referred to as artificial emotion intelligence or emotion AI) is the study and development of systems and devices that can recognize, interpret, process, and simulate emotion or other affective phenomena. With the rapid growth in the aging population around the world, affective computing has immense potential to benefit the treatment and care of late-life mood and cognitive disorders. For late-life depression, affective computing ranging from vocal biomarkers to facial expressions to social media behavioral analysis can be used to address inadequacies of current screening and diagnostic approaches, mitigate loneliness and isolation, provide more personalized treatment approaches, and …


Exercise As A Treatment For Cognitive Decline In Older Adults: The Role Of Growth Factors And Inflammatory Cytokines, Joshua A. Titus Dec 2021

Exercise As A Treatment For Cognitive Decline In Older Adults: The Role Of Growth Factors And Inflammatory Cytokines, Joshua A. Titus

Electronic Thesis and Dissertation Repository

The purpose of this thesis was to investigate the effects that exercise modalities have on neurotrophic and inflammatory blood markers and cognitive outcomes in older adults. A systematic review and meta-analysis were completed. The included studies illustrated that most of the literature evaluated the effect of aerobic exercise interventions on systemic concentrations of the blood marker brain-derived neurotrophic factor (BDNF). The review found that aerobic exercise increases BDNF and resistance training increases insulin-like growth factor 1 (IGF-1). Interventions with sex-specific cohorts presented advantages in males for blood marker and cognitive outcomes compared to females. One of three included interventions decreased …


Inter-Subject Correlation While Listening To Minimalist Music: A Study Of Electrophysiological And Behavioral Responses To Steve Reich’S Piano Phase, Tysen Dauer, Duc T. Nguyen, Nick Gang, Jacek P. Dmochowski, Jonathan Berger, Blair Kaneshiro Dec 2021

Inter-Subject Correlation While Listening To Minimalist Music: A Study Of Electrophysiological And Behavioral Responses To Steve Reich’S Piano Phase, Tysen Dauer, Duc T. Nguyen, Nick Gang, Jacek P. Dmochowski, Jonathan Berger, Blair Kaneshiro

Publications and Research

Musical minimalism utilizes the temporal manipulation of restricted collections of rhythmic, melodic, and/or harmonic materials. One example, Steve Reich’s Piano Phase, offers listeners readily audible formal structure with unpredictable events at the local level. For example, pattern recurrences may generate strong expectations which are violated by small temporal and pitch deviations. A hyper-detailed listening strategy prompted by these minute deviations stands in contrast to the type of listening engagement typically cultivated around functional tonal Western music. Recent research has suggested that the inter-subject correlation (ISC) of electroencephalographic (EEG) responses to natural audio-visual stimuli objectively indexes a state of “engagement,” demonstrating …


Boosting Brain Waves Improves Memory, Richard J. Addante, Mairy Yousif, Rosemarie Valencia, Constance Greenwood, Raechel Marino Nov 2021

Boosting Brain Waves Improves Memory, Richard J. Addante, Mairy Yousif, Rosemarie Valencia, Constance Greenwood, Raechel Marino

Psychology Student Publications

Have you ever wanted to improve your memory? Or have you struggled to remember what you studied? Memory uses special patterns of activity in the brain. This experiment tested a new way to create brain wave patterns that help with memory. We wanted to see if we could improve memory by using lights and sounds that teach the brain waves to be in sync. People wore special goggles that made flashes of light and headphones that made beeping noises. This trained the brain through a process called entrainment. The entrainment put the brain in sync at a specific brain wave …


Early Experience And The Functional Calibration Of The Stress-Response Systems, Niki Hosseini-Kamkar Nov 2021

Early Experience And The Functional Calibration Of The Stress-Response Systems, Niki Hosseini-Kamkar

Electronic Thesis and Dissertation Repository

Individuals exposed to adversities in childhood are at a greater risk of developing various diseases as adults, including cardiovascular disease and cancer (Felitti et al. 1998). These findings have sparked an interest in examining biological mechanisms that might explain the link between exposure to adversity and disease. To date, evidence has linked adversity to the function of the hypothalamic-pituitary-adrenal (HPA) axis. More recently, adversity has been associated with the function of the mesolimbic dopamine pathway as well.

This thesis uses a variety of techniques to explore the association between adversity and the function of the HPA axis and mesolimbic dopamine …

Social & Behavioral Health Faculty Publications

With the aging population, dementia emerges as a public health concern. In 2012, the Health and Retirement Study found that 8.8% of adults over 65 years suffered from dementia. The etiopathogenesis and treatment of dementia are not well understood. Antioxidant properties of Vitamin E and its major elements tocopherols and tocotrienols have been reported to be effective in slowing down the progression of dementia from its initial stage of Mild cognitive impairment (MCI). Therefore, the current review aims to explore the role of vitamin E on MCI. A literature search using the key words “Vitamin E, tocopherols, tocotrienols, and mild …


A Behavioral Study On The Adult Marmoset Interference Control In Spatial Working Memory, Mohadese Khosravi Najafabadi Nov 2021

A Behavioral Study On The Adult Marmoset Interference Control In Spatial Working Memory, Mohadese Khosravi Najafabadi

Electronic Thesis and Dissertation Repository

Interference control deficit in Working Memory (WM) is associated with neurodevelopmental disorders. The common marmoset (Callithrix jacchus) is an ideal non-human animal model for studying WM disorders. Previous studies of marmoset WM have used a touch-screen self-ordered sequencing task (SOST), which resembles an n-back paradigm and targets updating processes in internal interference control. However, the training time for the marmoset to reach proficiency on this paradigm is long given the short marmoset lifespan. In an attempt to accelerate marmoset learning of the task, we developed a new version of SOST that relied on foraging behaviour. The goal of …


Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy Nov 2021

Assessment Of Executive Function Using A Series Of Operant Conditioning Based Tasks In T1dm Rodents, Kevin T. Murphy

Electronic Thesis and Dissertation Repository

This study examined the impact of Type 1 Diabetes Mellitus (T1DM) on executive function using a series of operant conditioning based tasks in rats. Sprague Dawley rats were randomized to either non-diabetic (n = 12; 6 male) or diabetic (n = 14; 6 male) groups. Diabetes was induced using multiple low-dose streptozotocin injections. All diabetic rodents were insulin-treated using subcutaneous insulin pellet implants. At week 14 of the study, rats were placed on a food restricted diet to induce 5 - 10% weight loss. Rodents were familiarized and tested on a series of tasks that required continuous adjustments to novel …


Extended Functional Connectivity Of Convergent Structural Alterations Among Anxiety Disorders: A Meta-Analysis And Functional Connectivity Analysis, Brianna S. Pankey Nov 2021

Extended Functional Connectivity Of Convergent Structural Alterations Among Anxiety Disorders: A Meta-Analysis And Functional Connectivity Analysis, Brianna S. Pankey

FIU Electronic Theses and Dissertations

Anxiety-related disorders are some of the most pervasive mental health disorders affecting adult and youth populations. Despite growing evidence of the neurobiology associated with anxiety-related disorders, a consensus on the neurobiological mechanisms of anxiety-related disorders remains to be elucidated. We first provide background literature on the reasoning behind this dissertation in Chapter 1. In Chapter 2, we conducted a neuroimaging meta-analysis on posttraumatic stress disorder to identify convergent structural and functional alterations associated with this anxiety-related disorder among adults. In Chapter 3, we conducted a neuroimaging meta-analysis to identify convergent structural alterations across diverse groupings of anxiety-related disorders …


Investigation Of Memory Related Cortical Thalamic Circuitry In The Human Brain, Puck C. Reeders Oct 2021

Investigation Of Memory Related Cortical Thalamic Circuitry In The Human Brain, Puck C. Reeders

FIU Electronic Theses and Dissertations

This dissertation examined the role of medial prefrontal cortex (mPFC) and the hippocampus (HC) in episodic memory, and provides a novel approach to identify the midline thalamus mediating mPFC-HC interactions in humans. The mPFC and HC are critical to the temporal organization of episodic memory, and these interactions are disrupted in several mental health and neurological disorders. In the first study, I provide evidence that the mPFC is involved in ordinal retrieval, and the HC is active in temporal context retrieval in remembering the order of when events happen. In the second study, I focus on the anatomical basis of …


Role Of The Prefrontal Cortex In Reward Seeking Behaviors, Jessica Caballero-Feliciano Oct 2021

Role Of The Prefrontal Cortex In Reward Seeking Behaviors, Jessica Caballero-Feliciano

Doctoral Dissertations

Disorders associated with compulsive seeking of rewards, like binge-eating, are associated with abnormalities of the prefrontal cortex in humans, which is analogous to the prelimbic (PL) and infralimbic (IL) subregions of the medial prefrontal cortex (mPFC) in rodents. Although studies have examined the role of the mPFC in drug seeking behaviors, studies examining natural reward seeking behaviors (i.e. food and sucrose) are often unclear and contradictory. This dissertation aims to characterize the role of the PL and IL mPFC in operant sucrose seeking behaviors. We used pharmacological and chemogenetic tools to selectively inactivate the PL, IL and PL-nucleus accumbens (NAc) …


The Expression Of Guilt, Chloe A. Stewart Oct 2021

The Expression Of Guilt, Chloe A. Stewart

Electronic Thesis and Dissertation Repository

Though aversive, the experience and expression of guilt is important to healthy social functioning. Guilt is often described as visceral, and nonverbal guilt expressions are anecdotally observed, yet much remains unknown about how guilt is expressed. The present work aimed to explore the visceral experience of guilt via the autonomic nervous system (ANS), and the nonverbal display of guilt via facial, gestural, and postural expressions. Using a novel film paradigm, we explored ANS activity during guilt in healthy adults and adults with neurodegenerative disorders (NDs). We further explored the nonverbal behaviours associated with guilt in healthy adults. We hypothesized that, …


Understanding Neural Signals Related To Speech Processing In Humans During Sleep, Ashwin Harimohan Oct 2021

Understanding Neural Signals Related To Speech Processing In Humans During Sleep, Ashwin Harimohan

Electronic Thesis and Dissertation Repository

Many cognitive processes are surprisingly preserved during sleep, including the processing of basic language stimuli. However, whether the sleeping brain can process complex, natural speech is not yet known. The present study used regularized linear regression to understand which features of narrative speech, ranging from low-level acoustic information to higher-level linguistic information, are processed during sleep. Participants were exposed to an intact and scrambled narrative story while they were napping or lying awake. Temporal response functions (TRFs) mapped the relationship between participants’ EEG neural responses and the (1) auditory envelope, (2) word onsets and (3) semantic dissimilarity of words. For …


The Costs Of Developing Treatments For Alzheimer’S Disease: A Retrospective Exploration, Jeffrey L. Cummings, Dana P. Goldman, Nicholas R. Simmons-Stern, Eric Ponton Sep 2021

The Costs Of Developing Treatments For Alzheimer’S Disease: A Retrospective Exploration, Jeffrey L. Cummings, Dana P. Goldman, Nicholas R. Simmons-Stern, Eric Ponton

School of Medicine Faculty Publications

Introduction: With the exception of the recent accelerated approval of aducanumab, in over 26 years of research and development (R&D) investment in Alzheimer's disease (AD), only five novel drugs—all for symptomatic treatment only—have reached FDA approval. Here, we estimate the costs of AD drug development during this period in the private sector. Methods: To estimate private R&D funding, we collected information on AD clinical trials (n = 1099; phases 1–4) conducted between January 1, 1995 and June 21, 2021 from various databases. Costs were derived using previously published methodologies and adjusted for inflation. Results: Since 1995, cumulative private expenditures on …


The Motion Aftereffect: Mechanisms And Variants, Erica E. Hassoun Sep 2021

The Motion Aftereffect: Mechanisms And Variants, Erica E. Hassoun

The Cardinal Edge

The motion aftereffect causes a visual stimulus to undergo apparent motion. An adapting stimulus, which moves in a specific direction, adapts motion-responsive neurons in the middle temporal area (V5) to that direction of motion. Viewing a second stimulus, a test stimulus, produces apparent motion in the direction opposite that of the initial stimulus. Neural networks involved in attention and working memory are also implicated in the motion aftereffect. There is still little known regarding the mechanisms of the motion aftereffect, despite extensive documentation in the literature. This review discusses established knowledge of the motion aftereffect, focusing primarily on the middle …

Altered Theta Rhythm And Hippocampal-Cortical Interactions Underlie Working Memory Deficits In A Hyperglycemia Risk Factor Model Of Alzheimer’S Disease, Ryan A. Wirt, Lauren A. Crew, Andrew A. Ortiz, Adam M. Mcneela, Emmanuel Flores, Jefferson W. Kinney, James M. Hyman

Integrated Health Sciences Faculty Publications

Diabetes mellitus is a metabolic disease associated with dysregulated glucose and insulin levels and an increased risk of developing Alzheimer’s disease (AD) later in life. It is thought that chronic hyperglycemia leads to neuroinflammation and tau hyperphosphorylation in the hippocampus leading to cognitive decline, but effects on hippocampal network activity are unknown. A sustained hyperglycemic state was induced in otherwise healthy animals and subjects were then tested on a spatial delayed alternation task while recording from the hippocampus and anterior cingulate cortex (ACC). Hyperglycemic animals performed worse on long delay trials and had multiple electrophysiological differences throughout the task. We …


A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab Sep 2021

A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab

Dissertations, Theses, and Capstone Projects

Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …


Working Memory Task Performance In Children With Sli: A Behavioral And Erp Study, Megan V. Mcveety Sep 2021

Working Memory Task Performance In Children With Sli: A Behavioral And Erp Study, Megan V. Mcveety

Dissertations, Theses, and Capstone Projects

In addition to language deficits, children with Specific Language Impairment often show deficits in tests of various aspects of working memory, including capacity, updating, and selective attention. The purpose of the present study is to examine the specific drivers of differences in working memory processing in 8–11 year-old children with and without SLI using behavioral and electrophysiological measures. Participants completed an n-back task with three working memory load conditions (0-back, 1-back, 2-back), with the addition of distractor trials at the 1-back and 2-back levels. The SLI group performed significantly less accurately across all task conditions. The children with SLI also …


Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova Sep 2021

Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova

Dissertations, Theses, and Capstone Projects

Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after …


Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl Aug 2021

Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl

Symposium of Student Scholars

Do chemical pollutants that persistent in the environment and bioaccumulate in the body affect human health and behavior? Could these Persistent, Bioaccumulative, and Toxic (PBT) chemicals play a role in the cause of violent crimes due to deterioration of mental and cognitive functions? In the past, Mercury, a PBT chemical, has been shown in salmon to be associated with aggression. Could similar aggression occur in humans exposed to mercury through a toxic spill? Two sources of data are utilized in this analysis. The Environmental Protection Agency’s (EPA) Annual Toxic Release Inventory publishes data on toxic releases into the environment and …

Estimating Progression Rates Across The Spectrum Of Alzheimer’S Disease For Amyloid-Positive Individuals Using National Alzheimer’S Coordinating Center Data, Michele Potashman, Marric Buessing, Mihaela Levitchi Benea, Jeffrey Cummings, Soo Borson, Peter Pemberton-Ross, Andrew J. Epstein

School of Medicine Faculty Publications

Introduction: Published estimates of Alzheimer’s disease (AD) progression do not capture the full disease continuum. This study provides transition probabilities of individuals with amyloid-β (Aβ+) pathology across the disease continuum. Methods: Patient-level longitudinal data from the National Alzheimer’s Coordinating Center were used to estimate progression rates. Progression rates through five clinically defined AD stages—asymptomatic, mild cognitive impairment due to AD (MCI-AD), mild AD dementia, moderate AD dementia, severe AD dementia—and death were measured as transition probabilities. Rates were assessed in “incident” patients who recently entered the stage, controlling for covariates. Transition probabilities were generated from multinomial logit regression models that …


Intergenerational Transmission Of Functional Connectivity Profiles In Isolated Reading And Math Networks: A Scoping Review And Study Proposal, Ashini Peiris, Ira Gupta, Lien Peters, Eric D. Wilkey Aug 2021

Intergenerational Transmission Of Functional Connectivity Profiles In Isolated Reading And Math Networks: A Scoping Review And Study Proposal, Ashini Peiris, Ira Gupta, Lien Peters, Eric D. Wilkey

Undergraduate Student Research Internships Conference

The scoping review surveyed the existing literature on the topic of resting-state functional connectivity (rsFC) and mathematical cognition. The review revealed that rsFC is indicative of distinct long-term developmental trends in mathematical processing, alluding to individual differences in math abilities. Though there have been multiple studies that investigate individual differences in functional connectivity patterns related to math development and math learning disorders, no study has directly investigated to what degree these neurobiological factors are heritable. To address this topic, the following intergenerational transmission (IT) study is proposed. IT is the transfer of personal values, abilities, behaviours, and traits, from parents …


Task-Based And Resting-State Functional Connectivity In Children With Dyscalculia, Ira Gupta Aug 2021

Task-Based And Resting-State Functional Connectivity In Children With Dyscalculia, Ira Gupta

Undergraduate Student Research Internships Conference

Resting-state functional connectivity (RSFC) is a unique method in neuroimaging that measures the spontaneous neural activity as the brain is at rest, not actively undergoing any task. It is important in investigating brain patterns that result from brain regions working together throughout an individual’s development. The application of this technique has been limited in the mathematical cognition field, and thus, should be explored further. This preregistration poster focuses on the depth of the literature and studies available in regards to RSFC and math cognition through a scoping review, and then proposes a study in which task-based and resting-state functional connectivity …


Familiarity As A Motivator For Information-Seeking, Danielle Raynes-Goldfinger Aug 2021

Familiarity As A Motivator For Information-Seeking, Danielle Raynes-Goldfinger

Undergraduate Student Research Internships Conference

Curiosity is an integral part of motivation and results in information-seeking behaviors to obtain rewarding information. Theories on curiosity suggest that it occurs when an information gap is detected. Here, we explored whether the assessment of familiarity may result in the induction of curiosity. We employed 3 phases, the first involving memorization of face-name pairs. Next, participants were presented with new and the old faces and were asked to judge whether they fully remembered the name, whether the face was familiar despite the name being unrecallable, or whether the face nor name was familiar. To conclude, we allowed participants to …


Incorporating Action Information Into Computational Models Of The Human Visual System, Justin Zhou Aug 2021

Incorporating Action Information Into Computational Models Of The Human Visual System, Justin Zhou

Undergraduate Student Research Internships Conference

Deep convolutional neural networks (DCNNs) have been used to model the ventral visual stream. However, there have been relatively few computational models of the dorsal visual stream, preventing a wholistic understanding of the human visual system. Additionally, current DCNN models of the ventral stream have shortcomings (such as an over-reliance on texture data) which can be ameliorated by incorporating dorsal stream information. The current study aims to investigate two questions: 1) does incorporating action information improve computational models of the ventral visual system? 2) how do the ventral and dorsal streams influence each other during development?

Three models will be …


Investigating The Effects Of Maternal Immune Activation On Sensory Processing: Timing, Immune Mechanisms, And Gene-Environment Interactions, Faraj Haddad Aug 2021

Investigating The Effects Of Maternal Immune Activation On Sensory Processing: Timing, Immune Mechanisms, And Gene-Environment Interactions, Faraj Haddad

Electronic Thesis and Dissertation Repository

Maternal infection during the first or second trimester of pregnancy poses a risk factor for the child to have neurodevelopmental disorders like autism spectrum disorder (ASD) and schizophrenia. Various clinical and preclinical studies have shown that the maternal immune response to infection, also known as maternal immune activation (MIA), can disrupt fetal brain development.

Over the past two decades, MIA has been studied in rodents using the Polyinosinic Polycytidylic acid (Poly I:C) rodent model. Poly I:C has a molecular pattern resembling viruses that can induce a robust immune response. Following exposure to Poly I:C MIA, rodent offspring exhibit many brain …


Does Aberrant Connectivity Underlie The Experience Of Misophonia?, Kate Raymond Aug 2021

Does Aberrant Connectivity Underlie The Experience Of Misophonia?, Kate Raymond

Electronic Thesis and Dissertation Repository

Misophonia is a condition characterized by an extreme aversion to certain ordinary sounds, such as chewing or breathing. These sounds are typically innocuous but elicit strong feelings of anger, anxiety, and disgust as well as physiological stress in people with misophonia. This misophonic reaction to “trigger” sounds is also marked by increased activity in regions of the brain that process sound, ascribe salience, and regulate emotion (Kumar et al., 2017; Schroder et al., 2019). It has therefore been theorized that aberrant connectivity between these brain regions (particularly the anterior insula, auditory cortex, amygdala, and hippocampus) may underlie the experience of …

An Empirical Comparative Study On The Two Methods Of Eliciting Singers’ Emotions In Singing: Self-Imagination And Vr Training, Jin Zhang, Ziming Xu, Yueying Zhou, Pengpai Wang, Ping Fu, Xijia Xu, Daoqiang Zhang

Library Scholarship

Emotional singing can affect vocal performance and the audience’s engagement. Chinese universities use traditional training techniques for teaching theoretical and applied knowledge. Self-imagination is the predominant training method for emotional singing. Recently, virtual reality (VR) technologies have been applied in several fields for training purposes. In this empirical comparative study, a VR training task was implemented to elicit emotions from singers and further assist them with improving their emotional singing performance. The VR training method was compared against the traditional self-imagination method. By conducting a two-stage experiment, the two methods were compared in terms of emotions’ elicitation and emotional singing …
