A Novel Measure Of Narrative Self-Functioning And Its Role In The Transformative Potential Of Psychedelic Experience Across Clinical And Non-Clinical Participants, Nicole M. Amada Feb 2023

A Novel Measure Of Narrative Self-Functioning And Its Role In The Transformative Potential Of Psychedelic Experience Across Clinical And Non-Clinical Participants, Nicole M. Amada

Dissertations, Theses, and Capstone Projects

The eudaimonic field of well-being is founded on the idea that self-knowledge and the realization of one’s potential is at the heart of what it means to strive for well-being. While the “self” is at the core of this perspective, theories derived from this field have yet to incorporate neurocognitive conceptualizations of the self, and account for the collection of self-referential cognitions that influence striving for well-being. Such a theory and measure could fill this theoretical gap and be applied in person centered interventions to capture change in these processes over time. One such intervention utilizes psychedelic experience as a …


Developmental Differences In The Learning And Consolidation Of Linguistic Regularities, Sarah Berger Jul 2022

Developmental Differences In The Learning And Consolidation Of Linguistic Regularities, Sarah Berger

Electronic Thesis and Dissertation Repository

Relative to adults, children have a well-known advantage for learning linguistic regularities, which could be partially driven by their deeper sleep. To examine the relationship between consolidation and language learning across development, children and adults learned a novel article system with an implicit grammatical rule. Participants performed a judgment task on phrases containing the novel articles before and after a night of EEG-monitored sleep. We found that rule sensitivity emerged rapidly in children, whereas it did not emerge until the second session in adults. Children demonstrated better generalization of the rule than adults. Consolidation effects showed a developmental double dissociation, …


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 Dec 2021

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 …


Musical Meter: Examining Hierarchical Temporal Perception In Complex Musical Stimuli Across Human Development, Sensory Modalities, And Expertise, Jessica Erin Nave-Blodgett Aug 2020

Musical Meter: Examining Hierarchical Temporal Perception In Complex Musical Stimuli Across Human Development, Sensory Modalities, And Expertise, Jessica Erin Nave-Blodgett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performing, listening, and moving to music are universal human behaviors. Most music in the world is organized temporally with faster periodicities nested within slower periodicities, creating a perceptual hierarchy of repeating stronger (downbeat) and weaker (upbeat) events. This perceptual organization is theorized to aid our abilities to synchronize our behaviors with music and other individuals, but there is scant empirical evidence that listeners actively perceive these multiple levels of temporal periodicities simultaneously. Furthermore, there is conflicting evidence about when, and how, the ability to perceive the beat in music emerges during development. It is also unclear if this hierarchical organization …


Play's Role In The Development Of Antisocial Behavior, Cheyenne Vazquez Jan 2020

Play's Role In The Development Of Antisocial Behavior, Cheyenne Vazquez

Williams Honors College, Honors Research Projects

This paper is a literature review which examines the relationship between play and prosocial behavior. More specifically, it examines its inverse, questioning whether a lack of play in early childhood may be correlated to the development of antisocial behavior later in life. Comparing research from an abundance of psychologists, criminologists, and sociologists, this paper answers various questions pertaining to play and prosocial behavior: What happens if play is inhibited in childhood? Would different reasons for play to be inhibited result in different results (i.e. abusive childhoods, desperate situations such as homelessness and poverty, chronic illness, etc.)? Is a lack of …


The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker Dec 2019

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 …


Characterizing The Development Of Episodic Memory And Assessing The Reliability Of Fmri Measures, Lingfei Tang Jan 2019

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 …


The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg Dec 2018

The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg

Graduate Theses and Dissertations

Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents, yet have difficulty distinguishing between phonetically similar accents (Wagner, Clopper, & Pate, 2013). The present study aimed to determine whether the presence of dialect-specific vocabulary enhances young children’s ability to categorize speakers. Participants completed four training trials in which they were familiarized with photos of two children: one of whom used American English labels for test objects and one of whom used British English labels. After training trials, participants completed eight test trials in which they were asked to infer which target child would use …


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor Aug 2018

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard …


Infant Object Recognition: Two- And Three-Dimensional Visual Processing, Alexandra Chelsea Romano Aug 2017

Infant Object Recognition: Two- And Three-Dimensional Visual Processing, Alexandra Chelsea Romano

Masters Theses

Visual attention and recognition memory in infancy are highly dependent on the type of stimulus the infant is familiarized to and the conditions of familiarization. For example, in studies that initially exposed infants to test stimuli in laboratory settings (e.g., Courchesne, Ganz, & Norcia, 1981; Reynolds & Richards, 2005), the Negative Central (Nc) event-related potential (ERP) component associated with infant visual attention has shown greater amplitude for novel compared to familiar stimuli. Conversely, when initial stimulus exposure occured outside of the laboratory and the stimulus was highly familiar, studies have shown greater amplitude Nc to familiar compared to novel stimuli …


Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot Sep 2016

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …


Adult Development Of Positive Personality Traits Through Character Formation Mentoring, Robert Mark Colborn Jan 2016

Adult Development Of Positive Personality Traits Through Character Formation Mentoring, Robert Mark Colborn

Walden Dissertations and Doctoral Studies

Positive psychologists have published hundreds of empirical studies correlating positive personality traits with improved outcomes in mental health, physical health, academic and career success, resilience, relationships, and personal happiness. But there remains a dearth of research on the emergence and development of positive personality traits. This grounded theory, qualitative research sought to discover whether positive personality traits can be developed in adult mentoring relationships. Sixteen participants responded in structured interviews about the benefits of their mentoring experiences, and in addition to performing coding analysis as described by Strauss and Corbin (1990), the researcher also compared the answers to Peterson and …


Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang Jan 2015

Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang

Wayne State University Theses

The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …


Age-Related Aspects Of Mirror-Use By Bottlenose Dolphins (Tursiops Truncatus), Rachel A. Morrison Oct 2014

Age-Related Aspects Of Mirror-Use By Bottlenose Dolphins (Tursiops Truncatus), Rachel A. Morrison

Dissertations, Theses, and Capstone Projects

Bottlenose dolphins are neuroanatomically different and evolutionarily divergent from primates yet they exhibit mirror self-recognition (MSR), a rare cognitive ability in non-human animals. This research investigated the developmental and age-related aspects of MSR in this species. During a longitudinal study, a social group of bottlenose dolphins at the National Aquarium, Baltimore, MD were exposed to a mirror and their behavioral responses were recorded to: 1) further confirm the presence of MSR in this species, 2) determine the age of emergence of MSR and 3) draw comparisons with data documenting the emergence of this ability in humans and great ape species. …


Developmental Variation In Children's Acquisition Of Metrical Structure: How Early Treatment Of Stressless Syllables Can Inform Phonological Theory, Clifford S. Jones Jan 2010

Developmental Variation In Children's Acquisition Of Metrical Structure: How Early Treatment Of Stressless Syllables Can Inform Phonological Theory, Clifford S. Jones

Open Access Theses & Dissertations

The present study uses 26 color photos to elicit a total of 14 words conforming to a very specific pattern: a stressless syllable word-initially, followed by a stressed syllable, and at most one more stressless syllable. This was found to be a particularly difficult metrical structure for the two- and three-year old participants to produce in an adult-like manner. Based on the findings that a fairly reliable (if language-particular) order of acquisition is observable for contrasts of both place and manner of articulation, the case is made for a system of six emergent features, which may be characterized as combinable …
