Eye Movements For Learned Faces, Mariah Lehnertz 2019 Humboldt State University

Eye Movements For Learned Faces, Mariah Lehnertz

Theses and projects

Humans demonstrate a perceptual specialization for faces that is astonishing. This project attempts determine if and where within the perceptual process face perception and face recognition diverge at the level of eye movement behaviors. Participants were exposed to a series of 36 faces, of which six were randomly selected to be learned over five subsequent exposures; thus the same face identities served as both the novel faces (block 1) and the learned faces (block 5), allowing for the measurement of eye gaze patterns during initial face perception (novel) and face recognition (learned). These six faces were randomly assigned to different ...


Differences Between Nontraditional And Traditional College Students' Perceptions Of Transition Preparedness, Laila Erika Turner 2019 Walden University

Differences Between Nontraditional And Traditional College Students' Perceptions Of Transition Preparedness, Laila Erika Turner

Walden Dissertations and Doctoral Studies

While scholars have used Schlossberg's transition theory for more than 35 years to study college-to-work transition, researchers have yet to establish if there are meaningful differences in the perceptions of traditional and nontraditional college students regarding transition preparedness from college-to-work. Following the career transition model, this quantitative study was conducted to compare traditional and nontraditional college students' perceptions of transition preparedness, specifically the concepts of readiness, confidence, control, perceived support, and decision independence. The nontraditional students in this study were military veterans. The dependent variables were measured by the Career Transition Inventory (CTI) survey. Participants were selected via a ...


Stress, Social Support, And Mindfulness In Parents Of Children With Neurodevelopmental Deficits: A Quantitative Analysis, Branden D. Syrotchen 2019 Walden University

Stress, Social Support, And Mindfulness In Parents Of Children With Neurodevelopmental Deficits: A Quantitative Analysis, Branden D. Syrotchen

Walden Dissertations and Doctoral Studies

Parenting children with neurodevelopmental deficits (NDDs) is very stressful, more so than the parenting of typically developing children. There is considerable research on the topic of chronic stress experienced by caregivers; however, less is understood of parental stress experienced when raising children with NDDs. The purpose of this study was to examine how parental traits and habits, in the forms of mindfulness and social support levels, affect this cohort's general stress levels. The study was guided by Self-Determination Theory, which explored how parental acts could be classified along a continuum of being intrinsically or extrinsically derived. A convenience sample ...


Brain Neurotransmitters, Cognitive Control, And Resting Heart Rate Variability (Rhrv) In The Mri Environment, Max Povejsil 2019 University of Colorado, Boulder

Brain Neurotransmitters, Cognitive Control, And Resting Heart Rate Variability (Rhrv) In The Mri Environment, Max Povejsil

Undergraduate Honors Theses

Determining reliable measures that show how the brain can regulate the body and its physiological states could offer insight into how mental health and wellbeing is related to physiology and self-regulation. This study investigates how heart rate variability (HRV) at rest (rHRV), a measure of autonomic nervous system activity according to several studies (Thayer 2009, Colzato 2017, Shaffer & Ginsberg, 2017), relates to neurotransmitter levels in the prefrontal cortex (PFC), cognitive control over emotional material, and individual traits involved in psychopathology. Resting heart rate (HR) measures were taken via pulse rate measurements in an MRI scanner, and processed into rHRV. Prior ...


Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan 2019 Montclair State University

Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan

Animal Sentience

Humans have long viewed themselves in a favorable light. This bias is consistent with a general pattern of self-enhancement. Neural systems in the medial prefrontal cortex underlie this way of thinking, which, even when false, may be beneficial for survival. It is hence not surprising that we often disregard contrary evidence in believing ourselves superior.


Untangling The Reciprocal Relation Of The Behavioral And Physiological Immune Systems, Baris Sevi 2019 West Virginia University

Untangling The Reciprocal Relation Of The Behavioral And Physiological Immune Systems, Baris Sevi

Graduate Theses, Dissertations, and Problem Reports

In the past decade, there has been an exponential increase in the study of the Behavioral Immune System (BIS), a suite of psychological processes that serves an infectious disease avoidance function. The BIS is proposed to be inherently intertwined with the physiological immune system. However, very few studies have actually demonstrated this fundamental, theoretical assumption. The purpose of this thesis was to test the possible relation between the physiological and behavioral immune systems in two studies. In Study 1 (N = 388), the relation between implied activation of the physiological immune system and BIS sensitivity was examined. Participants who reported more ...


Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff 2019 East Tennessee State University

Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff

Animal Sentience

Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.


The Lived Experiences Of Adult Male Trauma Survivors With Dance Movement Therapy, Jeanne Langston 2019 Walden University

The Lived Experiences Of Adult Male Trauma Survivors With Dance Movement Therapy, Jeanne Langston

Walden Dissertations and Doctoral Studies

In the United States, approximately 7.7 million individuals are affected by posttraumatic stress disorder (PTSD) at any given time. Though women are likelier to develop PTSD symptoms, men are exposed to more traumatic events in their lifetimes. Empirically- supported PTSD options exist, however clinical application of these treatments may not consistently culminate in beneficial outcomes. Dance Movement Therapy (DMT) has demonstrated positive treatment outcomes for a variety of mental and physical disorders. Nonetheless, there is a lack of robust research related to the treatment experiences of men who have participated in DMT for trauma-related symptoms. The purpose of this ...


Diurnally Active Rodents For Laboratory Research, Roberto Refinetti, G. J. Kenagy 2018 Boise State University

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 the existing literature in showing that the ...

Title: Effects of Naltrexone on Alcohol and Nicotine Use in Female P Rats

Author: Usman Z. Hamid, Department of Psychology, University of Kentucky

Faculty Mentor: Michael T. Bardo, Ph.D., Department of Psychology, University of Kentucky

Alcohol is the most commonly abused substance worldwide. It is often co-abused with nicotine, which increases the difficulty of cessation of both alcohol and nicotine. Despite having similar mechanisms of action, there is no single medication to treat the co-abuse. The objective of the current study is to analyze the effects of the opiate antagonist naltrexone on alcohol consumption and the co-use of alcohol ...


Diversity And Inclusion In The Science Classroom, Sowmya Anjur 2018 Illinois Mathematics and Science Academy

Diversity And Inclusion In The Science Classroom, Sowmya Anjur

Faculty Publications & Research

A Diversity, Epidemiology and social justice unit was incorporated into the Physiology and Disease curriculum in Fall 2016. Students discussed topics such as social and cultural influences on diversity thinking, and selective treatment in hospitals based on race. It was very noteworthy that students were united in their thinking regarding diversity and inclusion, despite the fact that they were from different backgrounds and diverse cultures. In 2017, additional discussions were held on equity in education. Students who were otherwise reserved were encouraged enough to express their views, and everyone appreciated the fact that they had been included.


Temporal Information Guides Prefrontal Preparatory Activity, Jacqueline R. Janowich 2018 University of New Mexico

Temporal Information Guides Prefrontal Preparatory Activity, Jacqueline R. Janowich

Shared Knowledge Conference

Proactive preparation for an upcoming goal differs from last-minute reactive adaptation, but it is unclear how preparatory mechanisms change based on when in the future a goal needs to be executed. To assess how timing information is integrated into preparatory control, we designed a novel variant of the Dot Pattern Expectancy task, where each cue signaled both task rule and delay duration (known short, known long, or unknown) between cue and probe. We recorded EEG while healthy young adult participants (n=36) performed this task, and found that delay demands elicited distinct prefrontal preparatory activities. Medial prefrontal amplitude was sensitive ...


Electrocortical Responses During Script-Driven Emotional Imagery, Nicholas Best, Cassandra Gonzalez, David Herring Ph.D. 2018 Murray State University

Electrocortical Responses During Script-Driven Emotional Imagery, Nicholas Best, Cassandra Gonzalez, David Herring Ph.D.

Scholars Week

Emotional imagery is a common induction technique used in the laboratory and also employed in various exposure therapy treatments across the anxiety spectrum (e.g., specific and social phobias). Despite its clinical uses, there is a surprising dearth of literature regarding the basic central neural processes underlying emotional imagery, though other peripheral physiological processes have been investigated extensively using heart rate, skin conductance, and startle-blink responses. One imagery study that used a central nervous system psychophysiological measure -event specific brainwave or the event-related potential (ERP) technique- suggests the late positive potential (LPP) of the ERP is larger for unpleasant versus ...


Validation Of The Barkley Deficits Of Executive Functioning Scale-Short Form, Brian Sheble 2018 University of Missouri-St. Louis

Validation Of The Barkley Deficits Of Executive Functioning Scale-Short Form, Brian Sheble

Dissertations

The Barkley Deficits of Executive Functioning-Short Form (BDEFS-SF) is a short rating scale measuring executive functioning in adults. The BDEFS-SF was developed using the 5 highest loading questions from the BDEFS-LF. Consequently, the psychometric qualities of the BDEFS-SF were not investigated using formal methods. In this study, the psychometric attributes of the BDEFS-SF were examined using two separate but similar groups. The first group of 264 men and women aged 18-35 years old completed the BDEFS-SF via an internet survey. The second group of 36 men and women aged 18-35 years old completed the BDEFS-SF and individualized assessments of executive ...


Cannabinoid-Induced Behavioral Sensitization In Adolescent Sprague-Dawley Rats, Michelle Stone 2018 California State University, San Bernardino

Cannabinoid-Induced Behavioral Sensitization In Adolescent Sprague-Dawley Rats, Michelle Stone

Electronic Theses, Projects, and Dissertations

Adolescent cannabis use has grown because of increased availability and higher societal acceptance. This increase in cannabis use is problematic as adolescents who experiment with cannabis are more likely to abuse cannabis and experiment with other illicit drugs such as cocaine. The reason for the greater susceptibility to drugs use is unclear and may be the result of altered drug sensitivity after cannabis exposure. Thus, the present investigation used the behavioral sensitization paradigm to examine the behavioral response of early adolescent rats to the cannabinoid agonist CP 55,940 (CP) or cocaine after repeated cannabinoid administration. It was hypothesized that ...

Efficaciousness Of Mindfulness Interventions For Trauma Using Psychophysiological Measures: A Review, Sherief Y. Eldeeb 2018 Clark University

Efficaciousness Of Mindfulness Interventions For Trauma Using Psychophysiological Measures: A Review, Sherief Y. Eldeeb

Scholarly Undergraduate Research Journal at Clark

In recent decades the efficaciousness of mindfulness has been proven in a wide variety of contexts, but some crucial populations remain understudied. This review critically examines the literature on mindfulness in individuals with trauma using psychophysiological measures. Psychophysiological measures offer critical insight into this intersection of mindfulness and trauma due to the known somatic components in each, as well as serving as an objective response. Mindfulness-based treatments seem to show great promise in treating trauma, however there are significant limitations in the literature. Future studies should standardize the minimum length of treatment, utilize gender-balanced and ethnically diverse samples, and introduce ...

The Relationship Between Cognitive And Neural Bases Of Metamemory Judgments, Alexandra M. Gaynor

All Dissertations, Theses, and Capstone Projects

Metamemory monitoring, the process of making subjective assessments of the status of one’s own memory, is crucial to guiding behavior and effective learning. Past cognitive research has shown that subjective confidence judgments are inferential in nature, and based on cues available at the time of the judgment. When confidence is based on cues that are related to objective memory performance, metamemory accuracy is high. However, past studies have shown that metamemory monitoring tends to be inaccurate because individuals base their confidence on information that is not predictive of memory success, such as the fluency with which items were encoded ...


Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones 2018 The Graduate Center, City University of New York

Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones

All Dissertations, Theses, and Capstone Projects

The study of how the brain acquires fearful memories has attracted considerable experimental attention, due in part to the promise of discovering novel therapeutic approaches for psychiatric disorders that are characterized by unusually strong and persistent traumatic memories. In recent years, extensive research has focused on studying the neural and molecular mechanisms by which fear memories are acquired, stored, and retrieved in the brain. Once acquired, fear memories may be attenuated using one of 2 procedures: 1) fear extinction, which involves repeated presentation of the fear-arousing stimulus in the absence of an aversive consequence, or 2) interference with the reconsolidation ...
