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 …

Investigating The Electrophysiology Of Long-Term Priming In Spoken Word Recognition, Erin K. Bell

ETD Archive

When participants are listening to the same words spoken by different talkers, two types of priming are possible: repetition priming and talker-specific priming. Repetition priming refers to the exposure of a stimulus improving responses to a subsequent exposure. Talker-specific priming refers to the exposure of words spoken by same talkers improving responses relative to those same words spoken by different talkers. There are conflicting theories regarding whether talker-specific priming should be observed. Abstract representational theories suggest that episodic details (e.g., talker identity) are not stored in the mental lexicon, while episodic theories of the lexicon posit that lexical representations include …

Evaluating The Attitudes And Practices Of Exercise Prescription Among Psychotherapists, Igor Vasilj

Theses and Dissertations--Educational, School, and Counseling Psychology

Exercise has been shown to improve mood, anxiety, stress, and promote neuroplasticity (Conn, 2010; Donaghy, 2007; Josefsson, Lindwall, & Archer, 2014; Silveria et al., 2013; Stathopoulou et al., 2006). However, limited research on the topic suggests that many psychologists and mental health providers are not incorporating exercise into psychological treatment, and many lack the confidence to do so (Burton, Pakenham, & Brown, 2010; Weir, 2011). The purpose of this study was to evaluate current exercise prescription trends among practicing psychologists and trainees, including identifying their current beliefs, attitudes, training, and the perceived barriers hindering psychotherapists from recommending and prescribing exercise. …

The Behavioral Immune System: Homelessness As A Disease Marker, Anya O’Connor

Departmental Honors Projects

Alongside the biological immune system is the behavioral immune system that works to avoid infection by avoiding contact with potential disease. The behavioral immune system reacts to visual cues of potential disease, such as coughing or skin lesions, and promotes avoidance behavior via disgust reactions. It interacts with biological immune responses by influencing hormones such as Interleukin-6 and cortisol. The behavioral immune system has also been found to overgeneralize and react to cues, such as obesity, disability, and foreignness, that do not signal actual disease threat. The purpose of this study is to test if the behavioral immune system overgeneralizes …

Inflammation As A Central Mechanism In Alzheimer's Disease, Jefferson W. Kinney, Shane M. Bemiller, Andrew S. Murtishaw, Amanda M. Leisgang, Arnold M. Salazar, Bruce T. Lamb

Psychology Faculty Research

Alzheimer's disease (AD) is a progressive neurodegenerative disorder that is characterized by cognitive decline and the presence of two core pathologies, amyloid β plaques and neurofibrillary tangles. Over the last decade, the presence of a sustained immune response in the brain has emerged as a third core pathology in AD. The sustained activation of the brain's resident macrophages (microglia) and other immune cells has been demonstrated to exacerbate both amyloid and tau pathology and may serve as a link in the pathogenesis of the disorder. In the following review, we provide an overview of inflammation in AD and a detailed …

Attentional Bias To Alcohol In An In Vivo Setting, Ramey G. Monem

Theses and Dissertations--Psychology

The phenomenon of attentional bias to alcohol, where drinkers demonstrate a preference in allocating visual attention towards alcohol-related stimuli rather than neutral stimuli, is well-established. Studies detecting this phenomenon typically utilize computer-administered stimulus presentation tasks such as the visual dot probe task. Despite their frequency of use, these tasks do not represent the ways in which individuals typically encounter alcohol outside of the laboratory. Typical environments where alcohol is present allow individuals to move about freely and encounter alcohol while also being exposed to many other stimuli. This dissertation sought to implement a novel approach to assessing attentional bias in …

Holistic Health: Shaping Women’S Experiences Of Positive Body Image, Helen Elizabeth Monks

Theses: Doctorates and Masters

This PhD thesis seeks to contribute to a nuanced understanding of positive body image and how it is expressed among a group of women participating in holistic health culture in a modern Western society. Qualitative data were collected from in-depth ethnographic interviews with 25 women in Perth, Western Australia, to illuminate an understanding of their holistic health beliefs and practices, perceptions of appearance and health ideals, as well as their understandings of positive body image. Thematic analysis of the data through Nvivo revealed several overarching themes, demonstrating how certain aspects of holistic health culture may encourage or dissuade the development …

Neurofeedback With Fmri: A Critical Systematic Review, Robert T. Thibault, Amanda Macpherson, Michael Lifshitz, Raquel R. Roth, Amir Raz

Psychology Faculty Articles and Research

Neurofeedback relying on functional magnetic resonance imaging (fMRI-nf) heralds new prospects for self-regulating brain and behavior. Here we provide the first comprehensive review of the fMRI-nf literature and the first systematic database of fMRI-nf findings. We synthesize information from 99 fMRI-nf experiments—the bulk of currently available data. The vast majority of fMRI-nf findings suggest that self-regulation of specific brain signatures seems viable; however, replication of concomitant behavioral outcomes remains sparse. To disentangle placebo influences and establish the specific effects of neurofeedback, we highlight the need for double-blind placebo-controlled studies alongside rigorous and standardized statistical analyses. Before fMRI-nf can join the …

Stasi Brainwashing In The Gdr 1957 - 1990, Jacob H. Solbrig, Jacob Hagen Solbrig

LSU New Orleans Theses and Dissertations

This thesis examines the methods used by the Ministerium für Staatssicherheit (MfS), more commonly known as the Stasi, or East German secret police, for extraction of information from citizens of the German Democratic Republic for the purpose of espionage and covert operations inside East Germany, as it pertains to the deliberate brainwashing of East German citizens. As one of the most efficient intelligence agencies to ever exist, the Stasi’s main purpose was to monitor the population, gather intelligence, and collect or turn informants. They used brainwashing techniques to control the people of the GDR, keeping the populace paralyzed with fear …

Virtual Reality As A Training Tool To Treat Physical Inactivity In Children, Adam W. Kiefer, David Pincus, Michael J. Richardson, Gregory D. Myer

Psychology Faculty Articles and Research

Lack of adequate physical activity in children is an epidemic that can result in obesity and other poor health outcomes across the lifespan. Physical activity interventions focused on motor skill competence continue to be developed, but some interventions, such as neuromuscular training (NMT), may be limited in how early they can be implemented due to dependence on the child’s level of cognitive and perceptual-motor development. Early implementation of motor-rich activities that support motor skill development in children is critical for the development of healthy levels of physical activity that carry through into adulthood. Virtual reality (VR) training may be beneficial …

A Cluster Analysis Of Challenging Behaviors In Autism Spectrum Disorder, Elizabeth Stevens, Abigail Atchison, Laura Stevens, Esther Hong, Doreen Granpeesheh, Dennis Dixon, Erik J. Linstead

Mathematics, Physics, and Computer Science Faculty Articles and Research

We apply cluster analysis to a sample of 2,116 children with Autism Spectrum Disorder in order to identify patterns of challenging behaviors observed in home and centerbased clinical settings. The largest study of this type to date, and the first to employ machine learning, our results indicate that while the presence of multiple challenging behaviors is common, in most cases a dominant behavior emerges. Furthermore, the trend is also observed when we train our cluster models on the male and female samples separately. This work provides a basis for future studies to understand the relationship of challenging behavior profiles to …

Fatigue and perceived stress are commonly experienced by women during the MT and EPM. We sought to discover relationships between these symptoms and to employ these symptoms as possible markers for resilience.

Methods:

Participants were drawn from the longitudinal Seattle Midlife Women's Health Study. Eligible women completed questionnaires on 60+ occasions (annual health reports and monthly health diaries) (n = 56 women). The total number of observations across the sample was 4,224. …

Pediatric Medical Traumatic Stress: An Integrative Literature Review, Cassia Onken

Grace Peterson Nursing Research Colloquium

Pediatric Medical Traumatic Stress (PMTS) is a common occurrence and not well understood by the medical community. Therefore, identifying key concepts is necessary to provide early intervention for children and parents. The purpose of this literature review is to evaluate current research to determine common themes of PMTS. Questions included “What is known about the defining characteristics of PMTS?” and “What variable interactions predispose a child to PMTS development?” Articles were found using CINAHL, PsychInfo, PubMed, ProQuest, and Academic Search Complete using key words like acute stress disorder, post-traumatic stress, medical traumatic stress, pediatric, child, parent, and guardian. Studies had …

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, …

When Is Affect Variability Bad For Health? The Association Between Affect Variability And Immune Response To The Influenza Vaccination, Brooke N. Jenkins, John F. Hunter, Marie P. Cross, Amanda M. Acevedo, Sarah D. Pressman

Psychology Faculty Articles and Research

Objectives—This study addresses methodological and theoretical questions about the association between affect and physical health. Specifically, we examine the role of affect variability and its interaction with mean levels of affect to predict antibody (Ab) levels in response to an influenza vaccination.

Methods—Participants (N = 83) received the vaccination and completed daily diary measures of affect four times a day for 13 days. At one and four months post-vaccination, blood was collected from the participants to assess Ab levels.

Results—Findings indicate that affect variability and its interaction with mean levels of affect predict an individual’s immune response. …

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 …

Theta-Burst Microstimulation In The Human Entorhinal Area Improves Memory Specificity, Ali S. Titiz, Michael R. H. Hill, Emily A. Mankin, Zahra M. Aghajan, Dawn Eliashiv, Natalia Tchemodanov, Uri Maoz, John Stern, Michelle E. Tran, Peter Schuette, Eric Behnke, Nanthia A. Suthana, Itzhak Fried

Psychology Faculty Articles and Research

The hippocampus is critical for episodic memory, and synaptic changes induced by long-term potentiation (LTP) are thought to underlie memory formation. In rodents, hippocampal LTP may be induced through electrical stimulation of the perforant path. To test whether similar techniques could improve episodic memory in humans, we implemented a microstimulation technique that allowed delivery of low-current electrical stimulation via 100 μm-diameter microelectrodes. As thirteen neurosurgical patients performed a person recognition task, microstimulation was applied in a theta-burst pattern, shown to optimally induce LTP. Microstimulation in the right entorhinal area during learning significantly improved subsequent memory specificity for novel portraits; participants …

Psycho-Physiologic Emergentism; Four Minds In A Body, David L. Rowland, Ion G. Motofei

Journal of Mind and Medical Sciences

The mind-body problem represents one of the most debated topics in the neurosciences. From a psychological standpoint, abstract/non-material data are an intrinsic part of the mind, intervening to a large extent in reasoning and decision making processes. Imaging studies also show a strong correlation between higher cognitive functions (such as working memory) and specific cerebral brain regions (a fronto-parietal network of interacting left and right brain areas). In contrast, the physical/material brain would be unable to interact with abstract-immaterial data, such that the psychological processing of abstract data (processes such as thinking, reasoning, and judgment) is attributed to the mind, …

Anger Without Agency: Exploring The Experiences Of Stress In Adolescent Girls, Elin A. Björling, Narayan B. Singh

The Qualitative Report

Although a great deal of research has measured stressful life events and stress-related symptoms in adolescents, little research has qualitatively examined the experience of stress in teens. The purpose of this study was to utilize thematic analysis to explore how teen girls described their experiences of stress. Thirty-one girls, ages 14–18, were recruited for a study examining stress and stress-related symptoms. As part of this study, they participated in an open-ended, qualitative interview about their personal experiences of stress. Themes included the mind of stress, emotionally shutting out others, and “growing out of it.” The overarching finding was that all …

The Psychology Of Neurofeedback: Clinical Intervention Even If Applied Placebo, Robert T. Thibault, Amir Raz

Psychology Faculty Articles and Research

Advocates of neurofeedback make bold claims concerning brain regulation, treatment of disorders, and mental health. Decades of research and thousands of peer-reviewed publications support neurofeedback using electroencephalography (EEG-nf); yet, few experiments isolate the act of receiving feedback from a specific brain signal as a necessary precursor to obtain the purported benefits. Moreover, while psychosocial parameters including participant motivation and expectation, rather than neurobiological substrates, seem to fuel clinical improvement across a wide range of disorders, for-profit clinics continue to sprout across North America and Europe. Here, we highlight the tenuous evidence supporting EEG-nf and sketch out the weaknesses of this …
