Mental Workload Modulates The Effects Of Baroreceptor Afferents On Sensorimotor Processing, Xiao Yang, Katie Herberlein, Anthony Reid, Dongfang Jiao, Fang Fang

Psychology Faculty Publications

The heart–brain interaction is the main mechanism for maintaining normative physiological processes, and its dysregulation underlies the somatic symptoms of various mental disorders. Cortical inhibition, triggered by afferent signals from baroreceptor activation, induces systematic variations in sensorimotor responses within a cardiac cycle, with reaction times (RTs) slower at cardiac systole compared to diastole (known as cardiac cycle time effects). However, recent data suggest that baroreceptor afferents not only inhibit simple responses but also facilitate complex sensorimotor responses during cardiac systole. The mental workload that is implicated in complex responses may modulate the cardiac cycle time effects. The current study aimed …

Identifying Patterns For Neurological Disabilities By Integrating Discrete Wavelet Transform And Visualization, Soo Yeon Ji, Sampath Jayarathna, Anne M. Perrotti, Katrina Kardiasmenos, Dong Hyun Jeong

Computer Science Faculty Publications

Neurological disabilities cause diverse health and mental challenges, impacting quality of life and imposing financial burdens on both the individuals diagnosed with these conditions and their caregivers. Abnormal brain activity, stemming from malfunctions in the human nervous system, characterizes neurological disorders. Therefore, the early identification of these abnormalities is crucial for devising suitable treatments and interventions aimed at promoting and sustaining quality of life. Electroencephalogram (EEG), a non-invasive method for monitoring brain activity, is frequently employed to detect abnormal brain activity in neurological and mental disorders. This study introduces an approach that extends the understanding and identification of neurological disabilities …

An Ewas Of Dementia Biomarkers And Their Associations With Age, African Ancestry, And Ptsd, Mark W. Miller, Erika J. Wolf, Xiang Zhao, Mark W. Logue, Sage E. Hawn

Psychology Faculty Publications

Background

Large-scale cohort and epidemiological studies suggest that PTSD confers risk for dementia in later life but the biological mechanisms underlying this association remain unknown. This study examined this question by assessing the influences of PTSD, APOE ε4 genotypes, DNA methylation, and other variables on the age- and dementia-associated biomarkers Aβ40, Aβ42, GFAP, NfL, and pTau-181 measured in plasma. Our primary hypothesis was that PTSD would be associated with elevated levels of these markers.

Methods

Analyses were based on data from a PTSD-enriched cohort of 849 individuals. We began by performing factor analyses of the biomarkers, the results of which …

Comparison Between The Effects Of Acute Physical And Psychosocial Stress On Feedback-Based Learning, Xiao Yang, Brittany Nackley, Bruce H. Friedman

Psychology Faculty Publications

Stress modulates feedback-based learning, a process that has been implicated in declining mental function in aging and mental disorders. While acute physical and psychosocial stressors have been used interchangeably in studies on feedback-based learning, the two types of stressors involve distinct physiological and psychological processes. Whether the two types of stressors differentially influence feedback processing remains unclear. The present study compared the effects of physical and psychosocial stressors on feedback-based learning. Ninety-six subjects (Mage = 19.11 years; 50 female) completed either a cold pressor task (CPT) or mental arithmetic task (MAT), as the physical or psychosocial stressor, while electrocardiography and …

An Erp Measure Of Non-Conscious Memory Reveals Dissociable Implicit Processes In Human Recognition Using An Open-Source Automated Analytic Pipeline, Richard J. Addante, Javier Lopez-Calderon, Nathan Allen, Carter Luck, Alana Muller, Lindsey Sirianni, Cory S. Inman, Daniel L. Drake

Psychology Student Publications

Non-conscious processing of human memory has traditionally been difficult to objectively measure and thus understand. A prior study on a group of hippocampal amnesia (N = 3) patients and healthy controls (N = 6) used a novel procedure for capturing neural correlates of implicit memory using event-related potentials (ERPs): old and new items were equated for varying levels of memory awareness, with ERP differences observed from 400 to 800 ms in bilateral parietal regions that were hippocampal-dependent. The current investigation sought to address the limitations of that study by increasing the sample of healthy subjects (N = …

The Relationship Between Bipolar Disorder And Epilepsy: Challenging The Dichotomy Of Mental And Physical Health, Mia A. Dawbin

Psychology and Community Studies | Student Scholarship

Abstract

The body of literature associating epilepsy with mood disorders is vast and can be traced as far back as Hippocrates. The comorbidity of the two is notoriously high. The prevalence of depressive symptoms among people with epilepsy has been widely reported for decades, though these symptoms may not be considered or treated as successfully in people with epilepsy as they are in their non-epileptic counterparts. More recently, evidence has been found suggesting that psychiatric symptoms may serve as a precursor to epilepsy. The episodic nature of the illnesses and their congruent model of progression suggest a possible connection. The …

Integrating Interpersonal Neurobiology In Healthcare Leadership And Organizations, Lynn Redenbach

Antioch University Dissertations & Theses

Interpersonal Neurobiology (IPNB) is an interdisciplinary, science-based field that seeks to understand human reality including the nature of mind, brain, and relationships. IPNB has been used extensively by mental health practitioners as well as child development and parenting experts. While practitioners and scholars have described ways that IPNB can be used in leadership and organizations, there has been no systematic inquiry into the practical and phenomenological experience of this application. IPNB offers an alternative to dominant models of care and leading in healthcare settings and fields, which are characterized by disconnection, objectification, and separation. It offers a relationally centered approach …

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

Psychology Faculty 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 …

The Cerebellum's Relationship To Language Function Following Perinatal Stroke, Carolina Alexis Vias

FIU Electronic Theses and Dissertations

While recent studies have demonstrated the association between the cerebellum and higher-order cognitive functioning, it is still unclear how volumetric differences of specific regions of interests within the cerebellum across typical and atypical development are related to language function. We have done so by measuring the volume of cerebellar subregions of healthy controls, and compared the volume to behavioral measures of language function. We then followed with an analysis of the cerebellum’s relationship to language function following perinatal stroke, which provides us with a greater knowledge of the impact of a cortical injury on cerebellar development and the cognitive outcomes …

What Is The Readiness Potential?, Aaron Schurger, Pengbo 'Ben' Hu, Joanna Pak, Adina L. Roskies

Psychology Faculty Articles and Research

The readiness potential (RP) has been widely interpreted to indicate preparation for movement and is used to argue that our brains decide before we do. It thus has been a fulcrum for discussion about the neuroscience of free will.

Recent computational models provide an alternative framework for thinking about the significance of the RP, suggesting instead that the RP is a natural result of the operation of a stochastic accumulator process of decision-making, analyzed by time-locking to threshold-crossing events.

These models call for a reevaluation of: (i) the ontological standing of the RP as reflecting a real, causally efficacious signal …

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …

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 …

Associations Between Sleep And In-Race Gastrointestinal Symptoms: An Observational Study Of Running And Triathlon Race Competitors, Patrick Benjamin Wilson

Human Movement Sciences & Special Education Faculty Publications

OBJECTIVE: It remains unstudied whether poor sleep is involved in the etiology of gastrointestinal (GI) problems in athletes.

METHODS: Eighty-seven running and triathlon/duathlon race (>60 minutes) participants completed questionnaires to quantify the Sleep Problems Index-(SPI)-I and sleep parameters from the night before races. For GI symptoms, participants reported the severity (0-10 scale) of four upper and three lower symptoms during races. Spearman's correlations examined whether sleep measures were associated with in-race GI symptoms. Partial correlations were calculated to control for age, resting GI symptoms, and anxiety.

RESULTS: SPI-I scores correlated with in-race upper GI symptoms (rho=0.26, p=0.013). Controlling for …

Diurnally Active Rodents For Laboratory Research, Roberto Refinetti, G. J. Kenagy

Psychological Sciences Faculty Publications and Presentations

Although inbred domesticated strains of rats and mice serve as traditional mammalian animal models in biomedical research, the nocturnal habits of these rodents make them inappropriate for research that requires a model with human-like diurnal activity rhythms. We conducted a literature review and recorded locomotor activity data from four rodent species that are generally considered to be diurnally active, the Mongolian gerbil (Meriones unguiculatus), the degu (Octodon degus), the African (Nile) grass rat (Arvicanthis niloticus), and the antelope ground squirrel (Ammospermophilus leucurus). Our data collected under 12L:12D light-dark cycles confirmed and expanded …

Common Sense And Common Nonsense: A Conversation About Mental Attitudes, Science, And Society, Daniel S. Levine

Psychology Faculty Publications

Daniel S. Levine's Common Sense and Common Nonsense observes human decision making, ethics, and social organization as illuminated by the scientific disciplines of neural network theory, neuroscience, experimental psychology, and dynamical systems theory. It is a book whose aim is advocacy as well as research. Its goal is to use an understanding of our brains and minds to better operationalize Aldous Huxley's admonition to "try to be a little kinder." It wanders over examples from sociology, politics, economics, religion, literature, and many other fields but looks at all as examples of a few common themes. The "common nonsense" of the …

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz

Psychology Faculty Articles and Research

Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential …

Social Work Trauma Interventions: Dialectical Behavioral Therapy, Kassie Baumann

Senior Honors Theses

According to Lynne Weilart (2013), in her article on the reasons why people seek out therapy, trauma is the number one reason people attend counseling. Many different trauma-informed approaches are designed specifically to address the consequences of trauma and to facilitate healing. Some of these approaches are as follows: Cognitive Behavioral Therapy (CBT); Dialectical Behavioral Therapy (DBT);Mentalization Based Therapy (MBT); Trauma Systems Therapy (TST); Trauma Assessment Pathway (TAP); and Attachment, Self-Regulation, and Competency (ARC) (de Arellano, Danielson, Ko, & Sprauge, 2008). The effectiveness of each trauma intervention will be examined. DBT is one of these trauma interventions that is growing …

Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer

Honors Scholar Theses

Effort-related decision making tasks in animals can model motivational symptoms in humans, which are a set of symptoms spanning a multitude of neuropsychiatric disorders, such as major depressive disorder and the negative symptoms of schizophrenia. The present studies aimed to evaluate the effort-related effects of the Val158Met polymorphism of human catechol-methyltransferase (COMT), by testing mice carrying either the human COMT Val (n=8) or Met allele (n=8) with Wild-Type control mice (n=15) by using concurrent FR2 and FR4/pellet choice tasks in a touchscreen operant conditioning apparatus. The Val158Met polymorphism has been repeatedly associated with neuropsychiatric disorders, and the Val allele has …

The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh

Honors Scholar Theses

Usher syndrome type 2 is a complex autosomal recessive genetic disorder that is characterized by moderate to severe congenital sensorineural hearing loss, the onset of retinitis pigmentosa in the second decade of life, and in some cases, vestibular dysfunction. Mutations in the USH2A gene account for 85% of cases of type 2. The USH2A gene is responsible for encoding the protein usherin, which has an important role in the development and function of inner ear hair cells and retinal photoreceptors. Until recently, it has been believed that carriers of the USH2A mutation were phenotype free. However, recent data has suggested …

Identifying And Intervening On Neural Markers Of Attention To Threat In Children With Anxiety Disorders, Michele Bechor

FIU Electronic Theses and Dissertations

Objective: Attention Bias Modification Training (ABMT) for anxiety aims to train attention away from threatening stimuli and toward neutral stimuli. Although ABMT shows promising anxiety reduction effects in children and adolescents, no study has examined its influence on neural indicators of attention measured using event-related potentials (ERPs) in children or adolescents (i.e., youths). The present study examined the influence of ABMT on the P1, N170, P2 and P3 ERP components during completion of the emotional faces dot probe task in youths with anxiety disorders who failed to respond to cognitive behavioral therapy. Method: Thirty youths (M age = 11.97, …

Vmpfc Activation During A Stressor Predicts Positive Emotions During Stress Recovery, Xi Yang, Katelyn M. Garcia, Youngkyoo Jung, Christopher T. Whitlow, Kateri Mcrae, Christian E. Waugh

Psychology: Faculty Scholarship

Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood–oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts …

Analysis Of Endocrine Response To Perceived Difference In Cross-Cultural Interactions, Carole Woolford-Hunt, Marlene Murray, Tevni Grajales Guerra, Kristina Beenken-Johnson

Faculty Publications

We live in a world where awareness of ethnic and cultural diversity is an ever increasing reality. Business and education turn to the social sciences to inform them about how to manage and optimize cross-cultural interactions. Although much research has been done on the impact of cross-cultural interactions on a wide range of variables, one less researched area is the endocrine response to cross-cultural interactions. In this study we set out to investigate the endocrine response to cross cultural interactions and the impact of these interactions on perceived differences. To do so we measured the pre and post levels of …

Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

In this chapter, we proposed an overview of burnout, from the introduction of the construct in the mid-1970s to the growing realization that the syndrome was better conceived of as a depressive condition. Recent studies have shown that the distinction between burnout and depression is problematic, both theoretically and empirically. The history of burnout research suggests that transdisciplinary communication and methodological standards should be strengthened to avoid the proliferation of constructs that, in fact, refer to the same phenomena. Construct proliferation, a transgression of the scientific canon of parsimony, is considered a major problem today because it undermines theory building …

Occupational Health Psychology, Irvin Sam Schonfeld

Publications and Research

Occupational health psychology (OHP) is a cross-disciplinary subspecialty within psychology. OHP derives from two disciplines within applied psychology, health psychology and industrial/organizational psychology. OHP is also linked to disciplines outside of psychology, such as occupational medicine and public health. The discipline has roots in eighteenth, nineteenth, and twentieth century thinkers, including Adam Smith, Friedrich Engels, Karl Marx, Émile Durkheim, and Max Weber. These thinkers were concerned with the impact of the organization of work and the business cycle on human life. Later research by Elton Mayo, Marie Jahoda, Walter B. Cannon, Hans Selye, and investigators at the University of Michigan’s …

The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, John E. Kiat, Michael D. Dodd, Robert F. Belli, Jacob E. Cheadle

Department of Psychology: Faculty Publications

Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected …

Volition And Action In The Human Brain: Processes, Pathologies, And Reasons, Itzhak Fried, Patrick Haggard, Biyu J. He, Aaron Schurger

Psychology Faculty Articles and Research

Humans seem to decide for themselves what to do, and when to do it. This distinctive capacity may emerge from an ability, shared with other animals, to make decisions for action that are related to future goals, or at least free from the constraints of immediate environmental inputs. Studying such volitional acts proves a major challenge for neuroscience. This review highlights key mechanisms in the generation of voluntary, as opposed to stimulus-driven actions, and highlights three issues. The first part focuses on the apparent spontaneity of voluntary action. The second part focuses on one of the most distinctive, but elusive, …

Entrainment Of Voluntary Movement To Undetected Auditory Regularities, Aaron Schurger, Nathan Faivre, Leila Cammoun, Bianca Trovó, Olaf Blanke

Psychology Faculty Articles and Research

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked whether human subjects performing a tapping task would entrain their tapping to an undetected auditory rhythm surreptitiously introduced in the guise of ambient background noise in the room. Subjects performed two different tasks, one in which they tapped their finger at a steady rate of their own choosing and one in which they performed a single abrupt finger tap on each trial after a delay …
