Utilizing The Radsm Process: Developing An Unobtrusive Measure Of Cohesion, Zachary Lee Rahner

Theses and Dissertations

In this study, verbal indicators produced following the RADSM process were used to code transcript data collected from 62 three-person teams playing a cooperative bridge crew simulator. A training dataset, consisting of 88 mission transcripts, and a testing dataset, consisting of 39 mission transcripts, were created from the data. Multilevel modeling was employed to develop a linear-regression algorithm to predict/measure team task and social cohesion. The findings revealed that task cohesion perceptions are linked to the proportion of speech dedicated to information requests and instructions, whereas social cohesion perceptions are associated with the proportion of speech dedicated to amusing and …

Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …

Neurodevelopmental Processes In The Prefrontal Cortex Derailed By Chronic Hiv-1 Viral Protein Exposure, Kristen A. Mclaurin, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and …

Intelligence And Creativity In The Space-Time Continuum For Education, Business, And Development, Giovanni Emanuele Corazza, Roni Reiter-Palmon, Ronald A. Beghetto, Todd Lubart

Psychology Faculty Publications

In this paper, we address the relationship between the intelligence and creativity constructs, by providing equal-level definitions and a parsimonious description of context, allowing the identification of situations in which either one or the other construct prevails, as well as situations in which they overlap and collaborate. The description of context is performed by introducing the metaphor of the space-time continuum, crossing the dimensions of conceptual space S and available time span T, each one varying in continuity from extreme tightness to extreme looseness. The usefulness of the space-time continuum is not limited to the pure comparison between intelligence and …

Impulsivity And Brain Organization In Childhood Suicide: An Adolescent Brain And Cognitive Development (Abcd) Study, Katherine Lopez

Arts & Sciences Electronic Theses and Dissertations

Rates of suicide have steadily increased across all age cohorts, revealing a particularly concerning rise in suicide among much younger age groups (10-15 years old). Recent efforts aimed at understanding suicide in youth have leveraged work from the adult literature to more pointedly examine candidate risk factors associated with childhood suicide. A noteworthy body of work has begun to clarify the role that impulsivity plays in elevating suicide risk among adults and adolescents, a critical link warranting further research in childhood suicide given the vast and well-documented changes occurring in self-control and brain maturity throughout development. Here, we examined a …

Validating An Observational Coding System For The Dominance Behavioural System (Dbs) In Childhood, Jennifer Mullen

Electronic Thesis and Dissertation Repository

The dominance behavioural system (DBS) is a biologically based system that underpins individual differences in motivation for dominance and power. However, little is known about the DBS in childhood. In a pilot study aimed at developing a behavioural coding system for dominance, a key facet of the DBS, we collected and coded observational data from 58 children, assessed at ages 3 and 5-6. Between these ages, dominance was moderately stable, to a degree comparable to other early child temperament traits. Consistent with study hypotheses, boys were more dominant than girls, and dominance was negatively associated with children’s behavioural inhibition, effortful …

Investigating Developmental Changes In Scalp-To-Cortex Correspondence Using Diffuse Optical Tomography Sensitivity In Infancy, Xiaoxue Fu, John E. Richards

Faculty Publications

Significance: Diffuse optical tomography (DOT) uses near-infrared light spectroscopy (NIRS) to measure changes in cerebral hemoglobin concentration. Anatomical interpretations of NIRS data require accurate descriptions of the cranio-cerebral relations and DOT sensitivity to the underlying cortical structures. Such information is limited for pediatric populations because they undergo rapid head and brain development.

Aim: We aim to investigate age-related differences in scalp-to-cortex distance and mapping between scalp locations and cortical regions of interest (ROIs) among infants (2 weeks to 24 months with narrow age bins), children (4 and 12 years), and adults (20 to 24 years).

Approach: We …

The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea

FIU Electronic Theses and Dissertations

In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …

Exploring How Interpersonal Childhood Trauma Impacts Emotional Development, Kathleen Hobbs

Educational Specialist, 2020-current

Our earliest interactions in life lay the foundation of how we relate to ourselves and others throughout adulthood. When a child experiences abuse and neglect that is relational in nature, referred to as interpersonal childhood trauma, research shows that they are at a much higher risk to display emotional difficulties that have been found to contribute to extensive health consequences throughout the lifespan. Less has been documented however regarding exactly how this kind of trauma influences emotional development. The purpose of this paper is to explore the current research that exists on the relationship between interpersonal childhood trauma and emotional …

Early Communication Abilities Of 24-Month-Old Children With Williams Syndrome As Measured By The Communication Complexity Scale., Sean B. Woods

College of Arts & Sciences Senior Honors Theses

Williams syndrome (WS) is a neurodevelopmental disorder associated with intellectual disability accompanied by a distinct cognitive profile. Despite their socially outgoing nature, children with WS exhibit delayed communication development and specific deficits across various functions of communication. The purpose of this study was to describe the range of communication complexity observed in 24-month-olds with WS and determine relations between communication complexity and other areas of cognitive development. The communication complexity of 17 24-month-old children with WS was measured using the Communication Complexity Scale (CCS), which quantifies optimal and typical communication complexity, as well as optimal communication for Joint Attention (JA) …

Coparenting Among Families Of Treatment-Seeking Adolescents: Associations With Coping Behaviors And Psychological Adjustment, Andrew Joseph Flannery

Graduate Research Theses & Dissertations

In recent decades, the family literature has demonstrated that the influences of coparenting spread through the entire family system and also uniquely affect child and adolescent psychosocial outcomes. For example, extant evidence shows that coparenting influences the connection between marital conflict and adolescent psychosocial outcomes. However, the period of adolescence is underscored by novel stressors, as teenagers experience biological, psychological, social, and cognitive transformations. Moreover, the median age of onset for mood, anxiety, substance use, and impulse-control disorders is before 25 years of age and most frequently during adolescence. Additionally, the manner in which adolescents cope with stressors may buffer …

The Effects Of And Interventions For Trauma On Child And Adolescent Development, Jenna Clark

Senior Honors Theses

Trauma is generally defined as an event that causes a lasting impact on an individual, ranging from a natural disaster or medical trauma to abuse. Traumatic events greatly impact development, especially when experienced during childhood and adolescence. These first eighteen years of a child’s life can be divided into three main stages using Erikson’s psychosocial theory and Piaget’s cognitive development theory as these theories provide comprehensive insight into the development of a child. Because of the differences in traumatic experiences and the age of the child, the effects and manifestations of a trauma’s influence will vary between these three different …

Oppositional Behavior Parallels In Toddlers And Teens And Parent’S Response, Michele Dimmett

Walden Dissertations and Doctoral Studies

Parents seem to manage oppositional conduct of toddlers but struggle emotionally and physically with oppositional conduct of teenagers, despite similarities in the behaviors. Self-efficacy theory, psychological theory of development, and theory of mind guided the conceptualization of how parents perceive and respond to these two sensitive periods of development. This contrasted group quantitative study pursued measurable similarities in the experience of first-time parents of children aged 18-36 months and 14-15 years of age. Establishing parents’ confidence level in their parenting skills and how they perceive and respond to their child's oppositional behavior was also a factor. One hundred and seventy-five …

How Do We Learn To Hope? The Development Of The Parent Report Of Child Hope, Lauren A. Sparks

Wayne State University Dissertations

Hope has been shown to be an important protective factor, with hypothesized origins in early childhood (Snyder, 2002). However, despite the established importance of hope, little research to date has examined its developmental origins. Specifically, a lack of appropriate instrumentation represents a significant barrier to detecting hope in children under the age of eight years old. The current study meets this need by examining the reliability and validity of a novel parent-report measure of hope in early childhood, titled the Parent Report of Child Hope (PRCH). The PRCH represents an initial step towards understanding individual differences in early childhood hope. …
