The Choral Composer/Conductor Collective: An Ongoing Experiment In Musical Self-Governance, Julian D. Bryson

Theses and Dissertations--Music

C4: The Choral Composer/Conductor Collective and Triad: Boston’s Choral Collective are the first choirs to explore collectivity as a method of ensemble organization. While more traditional ensembles have a single artistic director, C4 and Triad share and rotate leadership responsibilities among the full membership. Artistic and logistical decisions develop through conversation, consensus, and/or voting.

This monograph draws primarily on interviews with thirteen current and former members of the two ensembles as well as the author’s personal experiences with Triad’s inaugural concert cycle to present a narrative description of member characteristics, governance, and operational processes. Interview responses are compared to relevant …

Human Brain Reacts To Transcranial Extraocular Light, Lihua Sun, Jari Peräkylä, Anselmi Kovalainen, Keith Ogawa, Pekka J. Karhunen, Kaisa M. Hartikainen

School of Science Faculty Works

Transcranial extraocular light affects the brains of birds and modulates their seasonal changes in physiology and behavior. However, whether the human brain is sensitive to extraocular light is unknown. To test whether extraocular light has any effect on human brain functioning, we measured brain electrophysiology of 18 young healthy subjects using event-related potentials while they performed a visual attention task embedded with emotional distractors. Extraocular light delivered via ear canals abolished normal emotional modulation of attention related brain responses. With no extraocular light delivered, emotional distractors reduced centro-parietal P300 amplitude compared to neutral distractors. This phenomenon disappeared with extraocular light …

Stimulus Statistics Change Sounds From Near-Indiscriminable To Hyperdiscriminable, Keith Kluender R., Christian E. Stilp

Department of Speech, Language, and Hearing Sciences Faculty Publications

Objects and events in the sensory environment are generally predictable, making most of the energy impinging upon sensory transducers redundant. Given this fact, efficient sensory systems should detect, extract, and exploit predictability in order to optimize sensitivity to less predictable inputs that are, by definition, more informative. Not only are perceptual systems sensitive to changes in physical stimulus properties, but growing evidence reveals sensitivity both to relative predictability of stimuli and to co-occurrence of stimulus attributes within stimuli. Recent results revealed that auditory perception rapidly reorganizes to efficiently capture covariance among stimulus attributes. Acoustic properties per se were perceptually abandoned, …

The Effect Of Inversion And Motor Expertise On Body Compatibility, Harrison M. Goodall Iii

Pomona Senior Theses

Previous studies have established that when a subject’s attention is directed to a specific body part, the subject is able to move that body part faster than a body part their attention was not drawn to. This is known as the body compatibility effect, and it has been shown that this effect only occurs when viewing upright images of the human body. In this study, we presented control subjects and expert acrobats with inverted and upright stimuli. We hypothesized that the amount of time the acrobats spent inverted would result in the acrobats exhibiting body compatibility effects for both upright …

Altruism, Alexander J. Field

Economics

Altruism is reflected in actions by one individual that benefit another, even when there is no expectation of reward. Altruism is often equated with selflessness and contrasted with selfishness, or alternatively, altruism is seen as other-regarding as opposed to self-regarding behavior. The latter usage is sometimes preferred because of difficulties in classifying behavior for which the individual acting altruistically receives a "warm glow" from helping others. The question raised in this instance is whether such an individual is actually selfish and, if so, whether there is any behavior that, after the fact, could not be interpreted as selfish.

The need …

Context-Dependent Seed Dispersal By A Scatter-Hoarding Corvid, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison, Alan C. Kamil

Avian Cognition Papers

1. Corvids (crows, jays, magpies and nutcrackers) are important dispersers of large-seeded plants. Studies on captive or supplemented birds suggest that they flexibly adjust their scatter-hoarding behavior to the context of social dynamics and relative seed availability. Because many corvid-dispersed trees show high annual variation in seed production, context-dependent foraging can have strong effects on natural corvid scatter-hoarding behavior.

2. We investigated how seed availability and social dynamics affected scatter-hoarding in the island scrub jays (Aphelocoma insularis). We quantified rates of scatter-hoarding behavior and territorial defense of 26 colormarked birds over a three-year period with variable acorn crops. …

Structural, Functional, And Behavioral Alterations To The Dopamine System In The Female Hiv-1 Transgenic Rat, Robert Francis Roscoe Jr.

Theses and Dissertations

HIV-associated cognitive disorders continue to affect approximately 25 million individuals worldwide, and its prevalence is expected to increase as the lifespan of HIV-1 infected individuals continues to improve. The HIV-1 transgenic rat expresses 7 of the 9 genes that encompass the virus, and is an appropriate model for studying chronic HIV-1 infection at a level that is controlled through combined antiretroviral therapy. Psychostimulant abuse is known to exacerbate HAND symptomology, but the psychostimulant methylphenidate is a first line of treatment for HIV associated cognitive inhibition. Dopamine transport abnormalities in the HIV-1 Tg rat have been well characterized through behavioral testing; …

Urban Stressors And Child Asthma: An Examination Of Child And Caregiver Models, Gillian G. Leibach

Theses and Dissertations

The purpose of the present study was to examine how low-income, racial and ethnic minority, urban families experience and manage their child’s asthma. The rationale for this study stems from existing literature on asthma disparities and documented predictors of increased asthma morbidity and mortality. In particular, this study considered how specific types of stress may disproportionately impact low-income, racial and ethnic minority, urban families that have a child with asthma. This study aimed to determine associations between urban stressors (stressful life events, perceived discrimination, subjective socioeconomic status) and child asthma outcomes (emergency department visits, school days missed, asthma control), and …

Behavioral Phenotyping Of Vmat1 Knockout Mice: Relevance To Neuropsychiatric Disorders, Kevin A. Webster Ph.D.

Theses and Dissertations

Schizophrenia is a debilitating mental disorder that causes a large economic burden and is prevalent across all cultures and countries around the world. Although both environmental factors and genetics are known to play an important role in the etiology of schizophrenia, the exact role of genetics and its interaction with environmental factors in an individual’s predisposition to develop schizophrenia is poorly understood. Schizophrenia is characterized by symptoms that include positive symptoms (e.g. delusions, hallucinations, disorganized thinking and speech), negative symptoms (e.g. avolition, anhedonia, depressive-like behavior), and cognitive dysfunctions (e.g. executive functioning deficits in learning and memory, attention, and vigilance). Genomic …

Evaluating The Pennebaker Paradigm With Bereaved Emerging Adults: Applications Of Text Analysis, Elizabeth A. Collison

Theses and Dissertations

Bereavement is an important research area as it can result in grief reactions that lead to serious psychological and health consequences, particularly for the at-risk group of emerging adults (Arnett, 2000; Balk, Walker, & Baker, 2010; Fisher, Murray, & Frazer, 1985; Stroebe, Schut, & Stroebe, 2007). Expressive writing is a well-researched intervention for trauma and adjustment, yet research repeatedly has revealed null results with the classic Pennebaker paradigm as a bereavement intervention (Stroebe et al., 2002; Stroebe, Schut, & Stroebe, 2006). It may be premature, however, to conclude expressive writing is ineffective for the bereaved due to limitations in extant …

Iv Prenatal Nicotine Exposure Modulates Α6, Α7, And Α4Β2 Nicotinic Acetylcholinergic Receptor Subunit Expression In Male And Female Neonatal And Adolescent Rat Offspring: An Autoradiographical Analysis, Amanda Morgan

Theses and Dissertations

Maternal smoke exposure produces long-term adverse cognitive and behavioral outcomes in offspring, including an increased likelihood of attention problems (e.g., attention deficit hyperactivity disorder; ADHD) and drug abuse. Preclinical research shows that gestational exposure to nicotine, the primary psychoactive compound in tobacco smoke, influences the neurodevelopment of attention and reward neuronal circuits. This study investigated hypotheses about five brain regions, to determine if prenatal nicotine (PN) exposure altered expression of nicotinic acetylcholine receptors (nAChRs). A low dose, intravenous nicotine (IV) exposure method was used to administer nicotine (0.05 mg/kg/injection) or saline, 3x/day on gestational days 8–21 (Treatment). Brain tissue was …

Categorizing Pro-Environmental Behaviors Using The Laypeople's Perspective, Ashley Jade Gillis

UNF Graduate Theses and Dissertations

Most efforts to categorize pro-environmental behaviors (PEBs) have focused on researchers’ – rather than laypeople’s – perceptions of PEBs. Drawing on the psychometric paradigm used to categorize environmental risks, we aimed to identify the PEB attributes salient to laypeople and, from that, determine the underlying dimensions of PEB. In Study 1, participants (n = 157) evaluated 30 PEBs through open-ended questions. The results revealed 21 attributes that laypeople commonly associate with PEBs. In Study 2, 250 MTurk participants rated 74 PEBs on the 21 attributes. An exploratory factor analysis revealed four factors underlying PEB: Factor 1 (Financial and Behavioral Cost), …

Rudeness And Ego Depletion, Daniel A. Zuardo

College of Graduate Studies: Theses & Dissertations

The present study sought to examine the effect that rudeness would have on ego depletion by having participants engage in a task where they would build Legos with a confederate who would be rude or neutral to them. Ego depletion was measured using a typing task on a computer where participants would type A+E+I+O+U+ until they wanted to stop. The results suggest that rudeness can cause ego depletion.

Further Exploring Processing Differences Between Geometric Shapes And Shape Words, Chelsea V. Scordas

College of Graduate Studies: Theses & Dissertations

The current study sought to expand upon the research of geometric shape processing in relation to theories of domain specificity and modularity. Sturz, Edwards, and Boyer (2014) presented results for possible processing differences between geometric shapes and geometric shape words. The authors found that when processing a bi-dimensional sample (i.e., a shape word transposed inside either the same or a different picture of a shape), there was asymmetric interference. Shape words would interfere with identifying the correct shape in a delayed match-to-sample (DMTS) task but there was no such interference from geometric shapes when identifying shape words. It was concluded …

Mate Selection Comparisons In Heterosexual And Homosexual Individuals, Daina Lee Wierzbinski

All Master's Theses

The effects of character traits and socioeconomic status on mate selection for both heterosexual and homosexual individuals was studied. The current study recruited 347 Central Washington University students who ranked the importance of descriptive traits in a potential long-term mate, and also reported how willing they were to date a fictional potential mate in both a short-term and long-term context. Participants also described themselves in a dating profile scenario. The findings support the hypothesis that women are more interested in traits that signal resource acquisition and high socioeconomic status, and also support the hypothesis that men are more interested in …

"Language Preference And Cognitive Availability Of Sexual Identity In Gay Japanese Bilinguals: An Analysis Of Habitual Use Of Linguistic Categories", Sebastian Cordoba

Dissertations and Theses

Sexuality is a very private matter in Japan. Japan’s cultural mores and concepts of family unity have led to very conservative attitudes toward homosexuality. For instance, gay people generally fear disgracing their families, and this fear might prevent them from revealing their sexual identity to others, and so keeping it secret. Thus, homosexuality in Japan is a highly controversial topic. Being gay in Japan is not as tolerated as it is in some Western cultures (McLelland, 2000). Homosexuality is an issue that is not acknowledged by mainstream Japanese society – it is taboo and not spoken about publicly. The present …

Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt

Animal Sentience

Key’s (2016) discussion of his claim that fish do not feel pain ignores the history of attempts to study the attribution of mental states to other species. Although willing to accept that mammals feel pain, Key claims that fish lack the mammalian neural mechanisms underlying pain and are unconscious of their experiences. Consequently, we do not need to be overly concerned about fishing practices that would otherwise be viewed as painful. Key uses a flawed anthropomorphic lens. All attributions of mental events to organisms other than oneself involve inferences derived from anthropomorphic processes through which we process physiological and behavioral …

Pain And Other Feelings In Humans And Animals, Antonio Damasio, Hanna Damasio

Animal Sentience

Evidence from neuroanatomy, neurophysiology, and neuropsychology suggests that the experience of feelings in humans does not depend exclusively on structures of the cerebral cortex. It does not seem warranted to deny the possibility of feeling in animals on the grounds that their cerebral cortices are not comparable to those of humans.

Where Is Pain In The Brain?, Marshall Devor

Animal Sentience

Key argues that fish cannot experience pain based on (1) brain imaging in humans, (2) consequences of lesions and (3) direct brain stimulation. Imaging indeed shows that pain-relevant signals reach the cortex, but not that they underlie the subjective experience of pain. Lesions and stimulation data are more to the point, but Key paints an idiosyncratic and misleading picture of their effects. S1 and S2 ablation does not eliminate evoked or spontaneous pain, although there may be up- or down-modulation. Likewise, stimulation of pain-associated cortical areas rarely induces pain, and pain almost never occurs at the onset of epileptic seizures. …

Falsifying The Null Hypothesis That “Fish Do Not Feel Pain", Brian Key

Animal Sentience

The reader of Animal Sentience may surmise that because the weight of the commentaries on my target article, “Why fish do not feel pain,” is leaning towards not supporting my argument, it follows that the premise "fish do not feel pain" is incorrect. However, science does not prevail by popular opinion. History is plagued with numerous (and often widely accepted) examples of biological phenomena being explained by mysterious forces. In the absence of a mechanistic understanding, the many different guises of vitalism (the principle that life involves a vital energy) are often invoked to explain the unknown. Spurious …

Exploring The Outcomes Of Rehabilitative Care For Veterans And Service Members Treated For A Disorder Of Consciousness In The Vha Emerging Conciousness Program, Janette A. Hamilton

Theses and Dissertations

Over the past several years, there has been an influx in patients being treated for polytraumatic injuries within the Veterans Health Administration (VHA), largely due to the wars in Afghanistan and Iraq, but also due to advances in life sustaining medical interventions. The polytrauma population includes veterans who have sustained a severe traumatic or non-traumatic brain injury, and a significant loss in cognitive and physical functioning, referred to as a disorder of consciousness. The purpose of the current study was to explore factors related to successful emergence from a disorder of consciousness, using a sample of veterans who were treated …

Acute And Chronic Effects Of Inhalants In Intracranial Self-Stimulation, Matthew Tracy

Theses and Dissertations

Inhalants are a loosely defined diverse group of volatile substances which people abuse. Despite widespread misuse of inhalants, there are limited preclinical methods available to study the reinforcement-like properties of inhalants. One procedure which has demonstrated substantial promise as a tool to investigate inhalant pharmacology is the intracranial self-stimulation (ICSS) procedure. ICSS utilizes pulses of electrical stimulation to the mesolimbic reward pathway to serve as a temporally defined and controlled operant reinforcer with a highly adjustable efficacy. The first aim of the project was to characterize the effects of commonly abused inhalants: including toluene, trichloroethane, nitrous oxide, isoflurane and R134a …

The Effects Of The Caterpillar Game On Classroom Behavior And Teacher Stress, Amber Jacoby

Masters Theses

A single-case, multiple baseline design was utilized to evaluate the effects of the Caterpillar Game, a classroom management system, on disruptive student behavior, teacher praise, and teacher stress. Three classrooms were included in the study (preschool, kindergarten, and second grade). When the Caterpillar Game was implemented across the three classrooms, student disruptive behavior decreased and teacher behavior-specific praise increased. Disruptive behavior and teacher praise results remained similar to intervention two to four weeks later and teachers reported being highly satisfied with the Caterpillar Game. One of the three teachers reported a decrease in stress. This study adds further support to …

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz

Electronic Theses and Dissertations

Prevention efforts targeted at children and adolescents are important because alcohol consumption contributes to the three leading causes of death in this among 12-20 year-olds: unintentional injury, homicide, and suicide. Research on the causes of alcohol misuse traditionally focused on pharmacological and genetic explanations, but models have expanded to include cognitive processes in the development of alcohol use patterns. Alcohol expectancies, or beliefs about the effects of alcohol, are an important influence on drinking behavior. Expectancies exist prior to the initial drinking experience, predict the onset of alcohol consumption, differentiate both children and adults in terms of light- and heavy-drinking …

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa

Electronic Theses and Dissertations

Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …

The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring

Electronic Theses and Dissertations

Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …

Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders

Electronic Theses and Dissertations

This work on trust in human-robot interaction describes a series of three experiments from which a series of predictive models are developed. Previous work in trust and robotics has examined HRI components related to robots extensively, but there has been little research to quantify the influence of individual differences in trust on HRI. The present work seeks to fill that void by measuring individual differences across a variety of conditions, including differences in robot characteristics and environments. The models produced indicate that the main individual factors predicting trust in robotics include pre-existing attitudes towards robots, interpersonal trust, and personality traits.

Supporting Situation Awareness Through Robot-To-Human Information Exchanges Under Conditions Of Visuospatial Perspective Taking, Elizabeth Phillips

Electronic Theses and Dissertations

The future vision of military Soldier—robot teams is one in which Soldiers and robots work together to complete separate, but interdependent tasks that advance the goals of the mission. However, in the near term, robots will be limited in their ability to successfully perform tasks without, at least, occasional assistance from their human teammates. A need exists to design, in robots, mechanisms that can support human situation awareness (SA) regarding the operations of the robot, which humans can use to provide interventions in robot tasks. The purpose of the current study was to test the effects of information exchanges provided …
