The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations & Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …

In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber

Electronic Thesis and Dissertation Repository

In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …

How Do Humans Process Magnitudes? An Examination Of The Neural And Cognitive Underpinnings Of Symbols, Quantities, And Size In Adults And Children, Helen Moriah Sokolowski

Electronic Thesis and Dissertation Repository

A striking way that humans differ from other species is our unique ability to represent and manipulate symbols. This ability to process numerical magnitudes symbolically (e.g., ‘three’, ‘3’) is widely thought to be supported by an ancient system that evolved to process nonsymbolic numerical magnitudes (i.e., quantities). In this thesis, I present four empirical studies to uncover whether symbolic representations are indeed supported by the system that evolved to process quantities, or if symbolic representations are sub-served by a similar but ultimately distinct system.

In experiments 1 and 2, I investigate how the adult brain processes symbols and quantities using …

Cognitive, Neural, And Educational Contributions To Mathematics Performance: A Closer Look At The Roles Of Numerical And Spatial Skills, Zachary C.K. Hawes

Electronic Thesis and Dissertation Repository

The principal aims of this thesis were to (1) provide new insights into the cognitive and neural associations between spatial and mathematical abilities, and (2) translate and apply findings from the field of numerical cognition to the teaching and learning of early mathematics.

Study 1 investigated the structure and interrelations amongst cognitive constructs related to numerical, spatial, and executive function (EF) skills and mathematics achievement in 4- to 11-year old children (N=316). Results revealed evidence of highly related, yet separable, cognitive constructs. Together, numerical, spatial, and EF skills explained 84% of the variance in mathematics achievement (controlling for chronological age). …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober

Dissertations, Theses, and Capstone Projects

Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

The Effect Of Peer Collaboration On Kinematic Problem Solving, Alyssa Deronda

Seton Hall University Dissertations and Theses (ETDs)

Kinematic problems, a type of physics problem that involves object motion, pose a challenge for adults (Caramazza, McCloskey, & Green, 1981; Kozhevnikov, Motes, & Hegarty, 2007; McCloskey, 1983b; McCloskey, Washburn, & Felch, 1983). Adults often incorrectly predict the path of a moving object despite having prior experience with moving objects or formal physics education (Caramazza et al., 1981; Kaiser, Jonides, & Alexander, 1986). One way to improve kinematic problem solving may be through peer collaboration. Working together with a partner to solve a problem allows both people to help each other remember important parts of a complex problem and discuss …

Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga

Arts & Sciences Electronic Theses and Dissertations

Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …

Exploring The Moderating Effect Of Maternal Scaffolding On The Temperament - Language Development Relationship, Chelsea L. Robertson

Electronic Theses and Dissertations

Many studies have examined the relationship between a child’s temperament and its effect on his or her early language development. However, few studies have investigated the detrimental effects a child’s negative affectivity may have on their language development and potential ways these effects may be limited through parental behaviors. The current study aimed to investigate if physical or verbal maternal scaffolding behaviors moderated the effect negative affect has on language development. Although it was expected that maternal encouragement of physical activity would play a moderating role in the relationship between temperament and language development, no such relationship was found. One …

Examining Successful Aging And Resilience After Disasters, Katie Elizabeth Stanko

LSU Doctoral Dissertations

Resilience, a psychological adaptive process and outcome, is the ability to return to normal functioning after a traumatic event, such as a natural disaster. Successful aging entails biological, psychological, and social factors. The Great Flood of 2016 in the greater Baton Rouge area caused catastrophic structural damage to thousands of homes and businesses. Some of these individuals had previously moved to the Baton Rouge area after receiving catastrophic damage during Hurricane Katrina in 2005. In this study, I investigated the role that age group (younger, middle-aged, older) and disaster exposure group (control, single exposure, double exposure) had on post-disaster well-being. …

Child Welfare: Trauma Informed Practice At Time Of Child Removal, Ester Garcia

Electronic Theses, Projects, and Dissertations

As of 2018, approximately 442,995 children are in the foster care system in the United States according to the federal statistics from the Children’s Bureau. Entry into the foster system involves the removal of children from their home, making it a traumatic experience. The purpose of this study was to examine social workers’ perceptions of what trauma informed practice means and what it looks like in child welfare removals. The study also clarifies what trauma informed practice (TIP) is and how it can be applied in child welfare’s organizational structure. This was a qualitative study in which child welfare social …

Empowering The Plus Size Body Using Dance As Therapy, Ashley Sampson

Expressive Therapies Capstone Theses

In Western society, having the “ideal” body image and size is a societal issue. It is advertised throughout media outlets that the “ideal” body is what should be desired, and any other body type is “abnormal”. This capstone thesis focused on the effectiveness of dance as therapy and changing the perspectives of all body types, to support and empower all bodies including plus-sized bodies. The use of individual interviews, in an open dialogue model, with a select few members (3) of Soul thru Sole, including the CEO of the dance company; which focuses on empowering women no matter their age, …

Differentiating Cognitive Deficits Between Adhd And In Utero Polysubstance Exposure, Dylan J. Seitz

Doctor of Psychology (PsyD)

ADHD is the most prevalent psychiatric disorder in children, affecting their executive and overall well-being as a result (Barkley, 2014; Shaw, Gogtay, & Rapoport, 2010). A rampant increase in new diagnoses of ADHD suggests the potential for misdiagnosis. Stimulants are the first line of treatment and associated with a number of deleterious long-term consequences for those misdiagnosed (Urban & Gao, 2014a). This is of particular concern for children prenatally exposed to substances as in utero use acts on similar neural mechanisms impacted by ADHD – leaving the children vulnerable to misdiagnosis and contraindicated intervention (Derauf, Kekatpure, Neyzi, Lester, & Kosofsky, …

Increasing Adult's Awareness Of The Importance Of End-Of-Life Care Discussions, Taylor Gardner

Capstone Projects and Master's Theses

For many American families, end-of-life care is often not discussed, until advanced illness or injury has fully disrupted everyday life. There are many benefits to discussing end-of-life care prior to any medical complications. Research has shown that individuals who plan their end-of-life processes with a hospice service provider and family members report a higher quality of death than individuals receiving common health care during their final six months of life. In order to make families and friends more comfortable with end-of-life discussions, I will conduct two one-hour educational sessions to students at California State University, Monterey Bay.

Increasing The Frequency Of Tutors' Reinforcement Of Compliance Behaviors, Sruthi Rameshkumar

Honors Theses

Abstract

Compliance behaviors occurring prior to the delivery of an instruction, such as handing over preferred items, making eye contact, and folding hands in the ready position help prepare students for success in discrete-trial training (DTT) interventions. These behaviors are usually taught in early intervention with a continuous reinforcement schedule, but once they are mastered, they are rarely revisited or maintained. Without intermittent reinforcement of these behaviors, they are likely to decrease in frequency and may lead to the use of restrictive or intrusive methods to gain compliance during DTT sessions. The current study used a multiple-baseline across participants design …

Students´ Perceptions About Verbal Aggression At The University Level, John Alexander Guevara, Laura Alejandra Peña, Lizeth Tatiana Prada

Licenciatura en Español y Lenguas Extranjeras

La agresión verbal producida en los espacios académicos ha sido una de las muestras de violencia con mayor interés y observación en las últimas tres décadas. Sin embargo, al momento de hablar de la existencia y las percepciones que tienen los estudiantes acerca de las agresiones verbales dentro de la Universidad, se evidencia una ausencia de estudios de investigación acerca de este contenido, lo que genera escasa atención por parte de investigadores, estudiantes y educadores en este campo. Este proyecto de investigación busca determinar y puntualizar las diferentes percepciones que tienen los estudiantes universitarios acerca de sus a lo que …

Proximity, Touching, And Testosterone: An Observational Study Of Mate Retention Tactics In Humans, Kraig Shattuck

Wayne State University Dissertations

Mate guarding behaviors are strongly selected for in species that suffer from infidelity and cuckoldry. Two forms of mate guarding behaviors that have been found in self-report studies on humans are proximity and touching. Proximity actively prevents infidelity though the physical act of being present. Touching indirectly prevents infidelity by signaling to any potential rivals that their partner is taken, as well as signaling to the partner that they are being watched. Testosterone is a hormone implicated in competition and aggression. When in the presence of a potential rival, testosterone levels tend to increase. This increase should be related to …

Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang

Wayne State University Dissertations

The ability to remember past events is critical for everyday life and showed robust improvement over development from childhood to adulthood. With advances in noninvasive neuroimaging methods such as functional MRI in recent years, research efforts have been focused on identifying neural correlates underpinning developmental gains in memory performance. In my dissertation work, using a widely-validated subsequent memory paradigm, I aim to characterize functional MRI correlates of memory development. Specifically, I focused my investigation on identifying age differences in the functional patterns of two brain regions critical for memory, the prefrontal cortex and the hippocampus. Focusing on the prefrontal cortex …

Multicase Historic Studies Of Innovative Work Behavior Among Intellectually Gifted Adults, Karen Denise Gaskins

Walden Dissertations and Doctoral Studies

ABSTRACT

This qualitative research study was conducted to examine whether investing in innovation and gifted intelligence would improve America's economic well-being. The investment issue became a problem because educational researchers researched innovation as creativity rather than as productive behavior. Moreover, in the literature, adult giftedness was perceived as negative development rather than as alternate normative behavior. The purpose of this research study was to generate new knowledge about innovation and adult giftedness. WICS (wisdom, intelligence, creativity, synthesized) theory of intelligence provided the theoretical framework because intelligence is a measure of human productivity potential. The neuropsychological conceptual framework facilitated a cognitive …

Exploring Higher Order Thinking Strategies In Georgia's Top Performing Middle Schools, Karen Kister

Ed.D. Dissertations

Developmental psychologists defined adolescent cognitive development as a period of time when individuals learn to mentally separate from adults and establish a self‑sufficient identity capable of the autonomous thought necessary to apply higher-order thinking. In contrast, college professors of the millennial generation stated that students demonstrate increased immaturity levels inconsistent with those of prior generations. Hence, the focus of this study was to examine the higher-order thinking strategies that teachers of adolescents have implemented within the five top performing middle schools in the state of Georgia. The findings offered a potential coexistence of higher-order thinking abilities and autonomous behavior and …

Body Processing And Attentional Patterns In Infancy, Rachel Lynn Jubran

Theses and Dissertations--Psychology

Bodies provide important social information, and adults benefit from this information by recognizing and responding appropriately to bodies. Body recognition is enabled by the fact that human bodies are defined by parts, such as the limbs, torso, and head, arranged in a particular configuration. To understand the development of social cognition, it is important to analyze and document how infants come to recognize bodies. Infants are sensitive to distortions to the global configurations of bodies by 3.5 months of age, suggesting an early onset of body knowledge. It was unclear, however, whether such sensitivity indicates knowledge of the location of …
