Visual Feedback Dominates The Sense Of Agency For Brain-Machine Actions, Nathan Evans, Steven Gale, Aaron Schurger, Olaf Blanke

Psychology Faculty Articles and Research

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily movements (sense of agency; SOA) has been well studied and a number of well-defined sensorimotor and cognitive mechanisms have been put forth, very little is known about the SOA for BMI-actions. Using an on-line BMI, and verifying that our subjects achieved a reasonable level of control, we sought to describe the SOA for BMI-mediated actions. Our results demonstrate that discrepancies between decoded neural activity and …

Variability Modifies Life Satisfaction's Association With Mortality Risk In Older Adults, Julia K. Boehm, Ashley Winning, Suzanne Segerstrom, Laura D. Kubzansky

Psychology Faculty Articles and Research

Greater life satisfaction is associated with greater longevity, but its variability across time has not been examined relative to longevity. We investigated whether mean life satisfaction across time, variability in life satisfaction across time, and their interaction were associated with mortality over 9 years of follow-up. Participants were 4,458 Australians initially at least 50 years old. During the follow-up, 546 people died. After we adjusted for age, greater mean life satisfaction was associated with a reduction in mortality risk, and greater variability in life satisfaction was associated with an increase in mortality risk. These findings were qualified by a significant …

The Effect Of Auditory Stimuli On Visual Time-To-Contact Perception, Chelsea L. Rugel

Senior Honors Projects, 2010-2019

Previous research has demonstrated that auditory and visual stimuli have individual effects on the accuracy of a person’s estimation of time-to-contact (TTC), the time at which two objects collide. Prior findings also suggest that there is cross-modal interference between vision and audition; however, this phenomenon has never been studied in a TTC situation. (Driver & Spence, 1998; Ichikawa & Masskura, 2006; Roseboom, Kawabe, & Nishida, 2013) In this study we attempted to fill in this research gap by examining the effect of auditory speed cues over visual speed cues in a two-dimensional TTC scenario, and by determining if an object’s …

Paradoxical Interaction Between Ocular Activity, Perception, And Decision Confidence At The Threshold Of Vision, Aaron Schurger

Psychology Faculty Articles and Research

In humans and some other species perceptual decision-making is complemented by the ability to make confidence judgements about the certainty of sensory evidence. While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness …

Is Younger Really Better? Age Differences In Emotion Perception, Kaitlyn Snyder

Mahurin Honors College Capstone Experience/Thesis Projects

Previous research suggests that younger adults outperform older adults on emotion-matching tasks because emotion recognition ability declines with age. These studies involved tasks in which participants identified a target emotion by selecting from multiple verbal labels. The use of multiple verbal labels placed great cognitive demand on participants, influencing the results that were found in such studies. In the present study, a computer emotion-matching task was used to determine differences between younger and older adults when presented with a target stimulus expressing one of five emotions (anger, fear, disgust, happiness, and sadness) and asked to match the target emotion to …

The Use Of Criminal Profilers In The Prosecution Of Serial Killers, Chelsea Van Aken

Themis: Research Journal of Justice Studies and Forensic Science

The purpose of this paper is to analyze the concept of criminal profiling in terms of serial killers in the United States. The research provided in this paper was found using the most recent research available on the topic. The FBI’s Behavioral Unit, or National Center for the Analysis of Violent Crime (NCAVC), is the current leading law enforcement agency that investigates these types of crimes. They utilize definitions, typographies, and motives to create a criminal profile to investigate serial killings. Ultimately, these profiles are inadequate because they are inconclusive and exclude multiple suspects that are potentially dangerous. Therefore, criminal …

An Investigation Of Aerobic Fitness, Perceived Quality Of Life And The Direct Effects Of Self-Determination Theory In College Students 2015, Alanna Darling

Master's Theses

There have been numerous studies examining the association between physical activity, motivation and quality of life. In contrast, studies focusing on aerobic fitness and its relationship with levels of motivation and perceived quality of life are lacking. The purpose of this study was to explore the relationship between a direct measure of aerobic fitness, behavioral regulations, and perceptions of quality of life in college-aged sample. Participants included both males (n=129; 21.1±1.8 years) and females (n=89; 20.8±1.4 years) who completed the Behavioral Regulations of Exercise Questionnaire-2 sub-scores and Perceived Quality of Life (PQoL) instruments. Participants then performed the Queen’s College Step …

Maternal Obesity And Incidence Of Depression, Caroline A. Habjan

Renée Crown University Honors Thesis Projects - All

Obesity is a national epidemic in the United States, which both directly and indirectly affects the social productivity of individuals, the American macro economy and individuals’ personal health and well being. Depression often interferes with an individual’s ability to work, sleep, study, eat, and enjoy life. A maternal state of both obesity and depression may cause serious adverse medical conditions in the mother’s child. Taking steps to treat depression and obesity are critical in the construct of modern medicine. This project yields results that have the potential to make treatment options better tailored, more efficient, effective and economically-sound for the …

The Role Of Attention In Ego-Depletion, Garrett Pollert

Graduate Theses and Dissertations

The resource model of ego-depletion is unable to account for the results of several ego-depletion studies, whereas a recent mechanistic revision by Inzlicht and Schmeichel (2012) has focused on the role of attention and motivation in an effort to explain the phenomenon. Assessment of attention's role in restrained and unrestrained eaters may provide evidence that motivation and attention work in tandem to affect one's ability to exert self-control. In this experiment, college-aged females participated in two studies to examine the role of attention in ego-depletion effects. Study 1 evaluated the effect of ego depletion on attention via a dot probe …

Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason

Master's Theses

Relational aggression involves the intentional infliction of harm via damaging one’s relationships or sense of belonging. Previous research suggests that relational aggression among children and early adolescents is correlated with social ostracism, poor psychological adjustment, anxiety, and depression in victims, and there is increasing evidence that many of these correlates apply to relational aggression among older adolescents and emerging adults. Efforts to identify predictors of relational aggression are underway; however, many variables which have been influential in understanding other forms of aggression have not yet been examined. The Five Factor Model (FFM) of personality is one example, as it has …

Frontal Lobe And Psychopathy, Shawna Germain

Themis: Research Journal of Justice Studies and Forensic Science

This research paper presents an analysis of the functions of the frontal lobe and how damage to the frontal lobe correlates to psychopathy. Initially, it will look at how damage to the frontal lobe obstructs frontal lobe functions. The decrease in executive function, due to a reduction of blood flow to the frontal lobe following a subarachnoid hemorrhage, is explored. The correlation between cortical thickness and impulsiveness in adolescence is examined. Subsequently, the issue is then examined through the observation of groups with psychopathy and how the diagnosis relates to their frontal lobes. One study compares individuals with psychopathy to …

The Plight Of The Lucluc: Examining The Deadly Mystery Of Nodding Syndrome, Ethan K. Mcgann

Senior Honors Theses

Nodding syndrome (NS) is an emerging epidemic neurological disease that is shrouded in mystery. It is currently only found in the post-conflict regions of South Sudan, northern Uganda, and Tanzania. NS occurs in children from the ages of five to fifteen and is characterized by a loss of motor control in the neck muscles. Seizure episodes can range in intensity from atonic to tonic-clonic, and the onset of the first episode generally marks the beginning of a decline in the child’s physical and mental health. NS is a progressive disease that generally results in physical wasting, stunted growth, behavioral difficulties, …

The Evolving Role Of Dendritic Spines And Memory: Interaction(S) With Estradiol, M. Frankfurt, V. Luine

Journal Articles

This article is part of a Special Issue "Estradiol and Cognition". Memory processing is presumed to depend on synaptic plasticity, which appears to have a role in mediating the acquisition, consolidation, and retention of memory. We have studied the relationship between estrogen, recognition memory, and dendritic spine density in the hippocampus and medial prefrontal cortex, areas critical for memory, across the lifespan in female rodents. The present paper reviews the literature on dendritic spine plasticity in mediating both short and long term memory, as well as the decreased memory that occurs with aging and Alzheimer's disease. It also addresses the …

The Effect Of Clinician Hardiness On Posttraumatic Growth And Trauma Based On Vicarious Trauma Exposure, Maria Anne Stevens

All Graduate Theses, Dissertations, and Other Capstone Projects

There is a gap in the literature that examines posttraumatic growth outcomes in clinical psychologists. Additionally, few studies have explored personality characteristics that can mitigate negative psychological outcomes and foster growth. This study examined if the same model of Posttraumatic Growth (PTG) would be found in clinical psychologists who work with trauma as those who have experienced a traumatic event. Confirmatory Factor Analyses (CFA) indicated moderate model fit. Additionally, the study assessed whether the relationship between cumulative Vicarious Trauma Exposure (VTE) and Secondary Traumatic Stress (STS), and cumulative VTE and PTG would depend on the moderator hardiness, but no significant …

The Anxiolytic Effects Of Self-Selected Music Among Primary Care Patients, Jennifer West-Gavin

PCOM Psychology Dissertations

The primary care setting is commonly referred to as the first line of medical treatment sought for health related services. Anxiety is one of the most frequently encountered mental health issues in primary care. The purpose of this study was to examine the level of state anxiety experienced among primary care patients, attending for routine and nonroutine appointments; its further purpose was to examine if self-selected relaxing music accounts for the greatest reductions in state anxiety among primary care patients, as compared with investigator-selected (classical) music, audio commercials, or no music. Patients included a primarily underserved primary care population between …

Hiroshima And Mass Trauma Today: Treating Post-Traumatic Stress Disorder In Individuals And Communities, Ashley Martinez

International ResearchScape Journal

At 8:15 am on August 6^th, 1945, the world and the way in which we fight wars changed forever. Immediately following the drop of the Little Boy atomic bomb, the city of Hiroshima was decimated, leaving the surviving citizens to deal with poverty, starvation, loss of loved ones, and utter destruction of their lives. After the bombing, survivors were left with burns, radiation poisoning, and physical scars. Unknown to the survivors of the atomic bombings, or Hibakusha, were the ensuing psychological and emotional damages. In 2014, we know more about traumatic experiences than in 1945. Studies from …

Inventory Of Cognitive Distortions: Validation Of A Measure Of Cognitive Distortions Using A Community Sample, Michael B. Roberts

PCOM Psychology Dissertations

The purpose of this study was to examine and evaluate further the psychometric properties of a self-report inventory of cognitive distortions using a nonclinical, community sample. A group of 474 individuals were contacted via the social networking site, Facebook, and through a college list-serve and were asked to complete multiple measures and also to send the link to other individuals, thus utilizing a snowball sample. The measures used included the Inventory of Cognitive Distortions (ICD), Dysfunctional Attitude Scale (DAS), Perceived Stress Scale (PSS), and a brief questionnaire to collect demographic information on each participant. Results revealed positive psychometric properties for …

The Effectiveness Of A Computer-Assisted, Cognitive-Behavior Program For Treating Anxiety Symptoms In Children With Autism Spectrum Disorder, Jennifer A. Zabel

PCOM Psychology Dissertations

Autism Spectrum Disorder (ASD) is a complex and multifaceted, neurodevelopmental disorder that severely impacts children and families across a variety of settings. Prevalence rates of ASD are continuing to increase rapidly, with sizeable intervention and treatment costs placed on families and society. Further complicating the matter, many individuals with ASD also evidence co-occurring anxiety symptoms or disorders and tend to be at a higher risk for developing such problems when compared to other clinical populations or typically developing children. This study investigated the effectiveness of a computer-assisted CBT program, Camp Cope-A-Lot (CCAL), in regards to reducing anxiety symptoms in four …

The Rewarding Nature Of Anger Rumination In Borderline Personality Disorder: An Fmri Investigation, Jessica R. Peters

Theses and Dissertations--Psychology

Anger rumination, or persistently dwelling on feelings of anger, is associated with borderline personality disorder (BPD) and related features, such as aggressive behavior and cognitive distortions. To develop more effective treatments, it is crucial to understand why individuals with BPD engage in anger rumination despite its negative outcomes. The activation of energy associated with anger, as well as feelings of justification and validation, may be experienced in the short-term as rewarding. This may prevent individuals with BPD from attempting to reduce their rumination.

Functional magnetic resonance imaging (fMRI) and behavioral methods were utilized to examine this theory in a sample …

Minding The Interpersonal Gap: Mindfulness-Based Interventions In The Prevention Of Ostracism, Alex T. Ramsey, Eric E. Jones

University Faculty Publications and Creative Works

Ostracism is a ubiquitous phenomenon, occurring across a broad range of social contexts and detrimentally impacting personal outcomes. Through enhanced present-moment attention and awareness, mindfulness-based interventions may help prevent this harmful behavior. The current research examined the role of state mindfulness in reducing the propensity to commit ostracism. This relationship was investigated in two studies: a field-based quasi-experiment (Study 1, n=. 51) and a laboratory-based experiment (Study 2, n=. 100). Both studies supported the utility of brief mindfulness-based interventions in reducing the propensity to ostracize others. The current studies support the relevance of mindfulness in addressing the substantial problem of …

Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton

Psychology Faculty Articles and Research

Access to calorie-dense foods, medicine, and other comforts has made modern humans healthier than our prehistoric ancestors in many respects. However, the epidemics of obesity, diabetes, and cardiovascular disease suggest that there are also drawbacks to modern living. Here, we address the question of whether the dramatic cultural changes that have occurred over the past century have inflated rates of postpartum depression, adding postpartum depression to the list of diseases of modern civilization. We review evidence from cross-cultural, epidemiological, and experimental studies documenting associations between postpartum depression and modern patterns of early weaning, diets deficient in essential fatty acids, low …

On Reporting The Onset Of The Intention To Move, Uri Maoz, Liad Mudrik, Ram Rivlin, Ian Ross, Adam Mamelak, Gideon Yaffe

Psychology Faculty Books and Book Chapters

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …

Pharmacological Interventions For Somatoform Disorders In Adults, Maria Kleinstäuber, Michael Witthöft, Andrés Steffanowski, Harm Van Marwijk, Wolfgang Hiller, Michael J. Lambert

Psychology Faculty Publications

Background: Somatoform disorders are characterised by chronic, medically unexplained physical symptoms (MUPS). Although different medications are part of treatment routines for people with somatoform disorders in clinics and private practices, there exists no systematic review or meta‐analysis on the efficacy and tolerability of these medications. We aimed to synthesise to improve optimal treatment decisions. Objectives: To assess the effects of pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform autonomic dysfunction, and pain disorder) in adults. Search methods: We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) (to 17 January 2014). This register …

Non-Pharmacological Interventions For Somatoform Disorders And Medically Unexplained Physical Symptoms (Mups) In Adults, Nikki Van Dessel, Madelon Den Boeft, Johannes C. Van Der Wouden, Maria Kleinstäuber, Stephanie S. Leone, Berend Terluin, Mattijs E. Numans, Henriëtte E. Van Der Horst, Harm Van Marwijk

Psychology Faculty Publications

Background: Medically unexplained physical symptoms (MUPS) are physical symptoms for which no adequate medical explanation can be found after proper examination. The presence of MUPS is the key feature of conditions known as 'somatoform disorders'. Various psychological and physical therapies have been developed to treat somatoform disorders and MUPS. Although there are several reviews on non‐pharmacological interventions for somatoform disorders and MUPS, a complete overview of the whole spectrum is missing. Objectives: To assess the effects of non‐pharmacological interventions for somatoform disorders (specifically somatisation disorder, undifferentiated somatoform disorder, somatoform disorders unspecified, somatoform autonomic dysfunction, pain disorder, and alternative somatoform diagnoses …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Exploring Parallels In The Bible, The Analects, And The Epic Of Gilgamesh, Cassidy Mcfarling

University Honors Program

The primary aim of this thesis is to explore parallels in The Epic of Gilgamesh, The Analects, and the Bible. By tracking and describing seven different areas of resemblance, the research illustrates philosophical and narrative overlap. More importantly, an examination of the psychological and social forces behind such literature suggests that correspondence in wisdom literature reveals universal concerns and desires that transcend cultural boundary.
