On The Evolutionary Origins Of Religious Belief, Robert Duane Howard

Graduate Theses and Dissertations

Religious belief is a byproduct of evolutionarily designed cognitive mechanisms. The ubiquity of religious belief and experience across human cultures is explained by our common human psychology; our domain-specific cognitive mechanisms give rise, collectively, to the phenomenon of byproduct religious belief/experience. In this thesis, I will examine what I call religion-generating cognitive mechanisms, and I will argue that byproduct raw god-beliefs are developed by cultures into refined god-beliefs. These refined god-beliefs are co-opted by evolutionary processes and are cultural adaptations. My conception of “religious belief” in terms of raw and refined god-beliefs allows a disambiguation of the term “religion,” and …

Applying The Philosophies Of The Beacon Model, Michael P. Raisch

Creativity and Change Leadership Graduate Student Master's Projects

The purpose of this project is to apply all the knowledge and skills learned from a master’s degree in Creative Studies at Buffalo State college combined with personal experience in order to share perspective on what a “Beacon” is and how its core values are the foundation for enriching your life as well as the lives of those around you and how it all relates to Creativity. Furthermore, this project applies the concepts from the Beacon model more deeply through supporting philosophies and how the Halloween holiday naturally serves as a Beacon. There is a relationship due to the fact …

Effects Of Dissonance And Disruption On Risky Decisions, Wyn E. Taylor

Psychology Theses - Archive

All choices develop first from the basic sensory stimuli to which our systems attend, consciously and unconsciously. The cognitive processes which form the basis of decision- making and contextual shifting require attention to both novel and familiar environmental features; from the overwhelming stimulus that assault our senses, we must figure out which environmental features are safe to ignore and those to which we must attend. Separate fast, emotional and slower rational decision processes described by a number of dual-processing theories have found compelling support in neuroscience research examining selective attention gating mechanisms. Indeed, these two systems appear to exert substantial …

Happiness In Modern Society: Why Intelligence And Ethnic Composition Matter, Satoshi Kanazawa, Norman P. Li

Research Collection School of Social Sciences

Recent developments in evolutionary psychology suggest that living among others of the same ethnicity might make individuals happier and further that such an effect of the ethnic composition on life satisfaction may be stronger among less intelligent individuals. Data from the National Longitudinal Study of Adolescent Health showed that White Americans had significantly greater life satisfaction than all other ethnic groups in the US and this was largely due to the fact that they were the majority ethnic group; minority Americans who lived in counties where they were the numerical majority had just as much life satisfaction as White Americans …

Examining The Dynamics Of Infant Face Processing Using State Space Grids, Andrea Jane Kayl

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this investigation we examined the potential processes underlying infant preferences for and categorization of male and female faces as well as the outcome of these preferences. Infants with female primary caregivers exhibit preferences for same-race females over males and categorize females more readily than males. Little is known, however, about how infants may arrive at these collective preferences and categorization abilities. In research settings infants are exposed to novel stimuli in relatively short periods of time, and their experiences outside of the lab may be imposing structure onto their learning in lab settings. We used state space grids (SSGs) …

Integration Of Audio-~Visual Emotional Information In Schizophrneia, Bern Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia (SZ) is a debilitating illness characterized by a number of perceptual and

cognitive deficits. Deficits in emotional judgment and perception are consistently identified, although less is known about the integration of emotional information from separate sensory modalities. This study investigates the integration of auditory and visual emotional information in schizophrenia and healthy controls through application of an emotion judgment task modeled after the McGurk effect. The emotional judgments of 54 participants (40 SZ and 14 control participants from the community) for auditory, visual, and bimodal phonemic stimuli conveying no lexical information were analyzed. Visual and auditory stimuli conveying joy …

Differences In Absenteeism Severity Among Community Youth, Kyleigh Kay Sheldon

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined the relationship between school absenteeism severity and specific clinical and family variables in 118 middle and high school youth aged 11-19 years recruited from two truancy settings. The primary aim was to determine specific clinical and family variables that may be predictive of absenteeism severity in community youth. A secondary aim was to examine the level of absenteeism that warrants the most clinical concern. Hypotheses for the proposed study were based on the premise that characteristics of a community sample of youth with problematic absenteeism would generally resemble those identified in previous clinical samples. The first set …

Effects Of Failure On Subsequent Performance In The Bottlenose Dolphin (Tursiops Truncatus), Lisa Kay Lauderdale

Master's Theses

The current study examined the immediate effects of two types of failure during operant-conditioning based training sessions in 11 bottlenose dolphins (Tursiops truncatus) at the U.S. Navy Marine Mammal Program in San Diego, CA. While learning a multi-faceted behavior not commonly found in nature, such as beaching, animals are likely to perform approximations of the behavior that are not successful and do not result in reinforcement. The effects of failure on beaching trials were systematically investigated over a three-month period by determining the mean failure rate and the probability of success after initial success, initial attempts, and initial …

Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, Megan S. Broadway

Master's Theses

The study of canine cognition can be useful in understanding the ontology and selective pressures that affect the development of cognitive abilities. Dogs have undergone intensive artificial selection yielding distinctive breeds which differ both phenotypically and behaviorally. Breed based cognitive differences have not been found but some studies suggest there may be differences in broader categories such as working disposition and sex. The influence of size on canine cognition has not been thoroughly addressed despite the fact that large dogs are often perceived to be ‘smarter’ than small dogs. This preconception has only recently been addressed and supported in one …

Same-Sex Socio-Sexual Interactions Among A Group Of Captive Bottlenose Dolphins (Tursiops Truncatus), Natalia Botero Acosta

Master's Theses

Bottlenose dolphins (Tursiops truncatus) frequently engage in non-reproductive sexual behavior, including homosexual encounters. In order to better understand the nature and function of these interactions, a longitudinal study of the patterns of association and the dynamics of initiator/recipient role exchange was conducted. Underwater video footage of a colony of bottlenose dolphins housed at the Roatan Institute for Marine Sciences (RIMS), collected between March of 2010 and May of 2013, was analyzed. Associations occurring during homosexual interactions were transitory for most individuals. Nonetheless, subsequent analyses allowed the rejection of the null hypothesis of random association, suggesting the existence of …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

The Role Of Valproic Acid, A Histone Deacetylase Inhibitor, In Reducing Anxiety Levels In Rats: An Epigenetics Study, Juliet Buteme

Honors College Theses

Rats, like humans, show personality traits: they are born with different anxiety levels (i.e., high (HAn) or low anxiety (LAn) levels). In this study, we investigated (1) if treatment with valproic acid (VPA) can lower anxiety level in trait anxiety rats and (2) how VPA may interact with environment (e.g., enriched (EE), standard (SE) and isolated environments (IE)). VPA is a deacetylase inhibitor that increases Histone 3 acetylation, a known epigenetic mechanism that interacts with stress response proteins, and treats epilepsy and mood disorders. Since rats reared in IE exhibit heightened anxiety levels as compared to those in EE, we …

Loss Aversion And Perspective Taking In The Sunk-Cost Fallacy, Veronika Rudd Tait

Theses and Dissertations

The sunk-cost fallacy (SCF) occurs when an individual makes an investment with a low probability of a payoff because an earlier investment has already been made. It is considered an error because a rational decision should not factor in now-irretrievable investments, as they do not affect current outcome likelihoods. Previous research has measured the tendency to commit the SCF by using hypothetical scenarios in which participants must choose to make a future investment or not after making an initial investment. There are many theories as to why people commit the SCF. Loss aversion, which is the preference for uncertain over …

Role Of Recent And Remote Context Exposures On Incubation Of Fear Memories, Peter Zambetti

Psychology

Studying learning and memory through the methods of Pavlovian fear conditioning has been a topic of behavioral neuroscience research for decades. Anxiety disorders such as post-traumatic stress disorder can be modeled in rodents through fear conditioning. This study took on a different approach to study the learning and recall of a fear memory by using a within subjects group. This group was tested at both a recent and remote interval. The recent timepoint was three days after conditioning and the remote timepoint was thirty-one days after conditioning. The timepoints are used to observe the effect the passage of time has …

The Role Of Sharing And Information Type In Children's Categorization Of Privileged And Conventional Information, Helana Girgis

Graduate Theses and Dissertations

Categorization is an essential part of our daily lives and an integral part of humans’ ability to function and interact within society. There are large bodies of research that document children’s categorization in domains such as natural kinds, artifacts and human kinds. One domain that has not been investigated is children’s ability to categorize different types of information; specifically conventional information, shareable to others with no restrictions, and privileged information, shareable to only a few. Study 1 investigated 4- and 5-year-olds and adults’ ability to categorize conventional and privileged information. All participants correctly categorized both types of information equally well …

Problem Solving And Tool Use In Three Species Of Otter, Robert F. Gormley

Masters Theses and Doctoral Dissertations

Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis predicts complex cognitive capacities in socially complex species. Using the Aesop’s Fable paradigm – wherein subjects drop stones into a cylinder half-filled with water to acquire floating out-of-reach food items – I assessed North American river otters’, Asian small-clawed otters, and giant river otters abilities to solve a novel tool-mediated problem. Sticks and water were presented with the …

Sexual Minority Stigma And System Justification Theory: How Changing The Status Quo Impacts Marriage And Housing Equality, Jordan A. Blenner

Department of Psychology: Dissertations, Theses, and Student Research

Sexual minorities (i.e. lesbians and gay men) experience systemic discrimination throughout the United States. Prior to the Supreme Court ruling in Obergefell v. Hodges (2015), in many states, same-sex couples could not marry and sexual minorities were not protected from sexual orientation housing discrimination (Human Rights Campaign, 2015). The current, two-experiment study applied Jost and Banaji’s (1994) System Justification Theory to marriage and housing discrimination. When sexual minorities question dissimilar treatment, thereby threatening the status quo, members of the heterosexual majority rationalize sexual minority discrimination to maintain their dominant status (Alexander, 2001; Brescoll, Uhlmann, & Newman, 2013; Citizens for Equal …

Increases In Perspective Embedding Increase Reading Time Even With Typical Text Presentation: Implications For The Reading Of Literature, D. H. Whalen, Lisa Zunshine, Michael Holquist

Publications and Research

Reading fiction is a major component of intellectual life, yet it has proven difficult to study experimentally. One aspect of literature that has recently come to light is perspective embedding (“she thought I left” embedding her perspective on “I left”), which seems to be a defining feature of fiction. Previous work (Whalen et al., 2012) has shown that increasing levels of embedment affects the time that it takes readers to read and understand short vignettes in a moving window paradigm. With increasing levels of embedment from 1 to 5, reading times in a moving window paradigm rose almost linearly. However, …

Word-Length Correlations And Memory In Large Texts: A Visibility Network Analysis, Lev Guzmán-Vargas, Bibiana Obregón-Quintana, Daniel Aguilar-Velázquez, Ricardo Hernández-Pérez, Larry S. Liebovitch

Publications and Research

We study the correlation properties of word lengths in large texts from 30 ebooks in the English language from the Gutenberg Project (www.gutenberg.org) using the natural visibility graph method (NVG). NVG converts a time series into a graph and then analyzes its graph properties. First, the original sequence of words is transformed into a sequence of values containing the length of each word, and then, it is integrated. Next, we apply the NVG to the integrated word-length series and construct the network. We show that the degree distribution of that network follows a power law, P(k)∼k−γP(k)∼k-γ, with two regimes, which …

Strategies And Resources To Enhance Test Evaluation And Selection, Janet F. Carlson, Nancy Anderson

Buros Center: Professional Staff Publications

Testing serves an important function for SLPs in offering an evidence base that is useful in screening, diagnosing, monitoring progress, and documenting outcomes. Tests are used to measure diverse constructs such as communication, literacy, oral and written language, receptive and expressive vocabulary, articulation, phonological awareness and processing, and auditory perception and processing. In addition, specific impairments may require specialized measures to evaluate conditions such as stuttering and orthographic competence.

When using tests to diagnose language impairments, Betz, Eickhoff, and Sullivan (2013) suggest that SLPs consider carefully a test’s psychometric properties, particularly because of the “increasing emphasis on evidence-based practice, specifically, …

The Effect Of Motivation And Positive Affect On Ego Depletion: Replenishment Versus Release Mechanism, Ze Zhu, Jian Li, Bo Zhang, Ye Li, Houcan Zhang

Psychology Faculty Publications

In this study, 2 experiments were conducted to investigate whether motivation and positive affect can alleviate ego depletion and to elucidate their possible mechanisms. In Experiment 1, a crossing-out-letter task was adapted to reach an ego depletion state for Chinese participants. Participants were then randomly assigned to the extrinsic motivation group, the positive affect group or the depletion control group. After the experimental treatment, a dumbbell task was used to measure participants' remaining self-regulatory resources. The results showed that participants in the motivation and positive affect groups performed better on the dumbbell task than participants in the depletion control group. …

An Animal Model Of Flashbulb Memory: Insights Into The Time-Dependent Mechanisms Of Memory Enhancement, Laura Ashley Bullard

USF Tampa Graduate Theses and Dissertations

The vivid memory of an emotional event, as well as memory for incidental details associated with the arousing event, has been referred to collectively as a “flashbulb memory”. An important aspect of flashbulb memory in people is that an emotional event enhances memory of contextual details, such as the weather, or clothes one was wearing at the time of the event. Therefore, an emotional event not only produces a detailed memory of the event, itself, but also enhances memory for contextual details that would otherwise not be remembered. The first goal of this work is to describe the development of …

The Effect Of An Alcohol Cue On A Risk Taking Task, Patrick Mcgee Logan

USF Tampa Graduate Theses and Dissertations

Laboratory-based tasks of impulsivity and related constructs can be useful in predicting alcohol use. Performance on these tasks is generally assumed to reflect traits that remain stable across situations. However, several studies have indicated that manipulations of state-like variables (e.g., mood or stress) can influence levels of impulsivity demonstrated on the tasks. Furthermore, environmental context (in the form of physical setting, or contextual cues) has a demonstrable effect on tasks relevant to alcohol-related risky behaviors (e.g., ad lib drinking tasks). Importantly, this effect of context on behavior is dependent on the individual's alcohol expectancies. It is unknown, however, whether alcohol-related …

"Casting Aside That Ficticious Self.": Deciphering Female Identity In The Awakening 2015, Anne L. Dicosimo

Master's Theses

Kate Chopin’s female protagonists have long since fascinated literary critics, raising serious questions concerning the influence of nineteenth-century female gender roles in her writing. Published in 1899, The Awakening demonstrates the changeability of the various representations of woman. In the nineteenth century, the subject of women may be divided into two categories: the True Woman and the New Woman. The former were expected to “cherish and maintain the four cardinal virtues of piety, purity, submissiveness and domesticity” (Khoshnood et al.), while the latter sought to move away from hearth and home in order to focus on education, professions, and political …

Factors Influencing The Impact Of Aggressive And Violent Media On Children And Adolescents, Ashlee M. Wiedeman, Jacqueline A. Black, Autumn L. Dolle, Emmanuel J. Finney, Kendell L. Coker

Psychology Faculty Publications

The influence of aggressive and violent media on children and adolescents has been a topic of concern for several decades. Research on this topic has suggested that both short term and long term exposure to aggressive/violent media can negatively impact this population. The purpose of this literature review is to discuss relevant research on the topic and examine various factors that may impact the risk of being influenced by this type of media. These factors can include time spent viewing media, content of the media viewed, gender, age, psychological characteristics, family, and peers. Various theoretical approaches to explaining the influence …

Behavioral, Perceptual, And Neural Alterations In Sensory And Multisensory Function In Autism Spectrum Disorder., Sarah H Baum, Ryan A Stevenson, Mark T Wallace

Brain and Mind Institute Researchers' Publications

Although sensory processing challenges have been noted since the first clinical descriptions of autism, it has taken until the release of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013 for sensory problems to be included as part of the core symptoms of autism spectrum disorder (ASD) in the diagnostic profile. Because sensory information forms the building blocks for higher-order social and cognitive functions, we argue that sensory processing is not only an additional piece of the puzzle, but rather a critical cornerstone for characterizing and understanding ASD. In this review we discuss what …

Handedness For Unimanual Grasping In 564 Great Apes: The Effect On Grip Morphology And A Comparison With Hand Use For A Bimanual Coordinated Task, A. Meguerditchian, Kimberley A. Phillips, A. Chapelain, L. M. Mahovetz, S. Milne, T. Stoinski, A. Bania, E. V. Lonsdorf, J. Schaeffer, J. Russell, William D. Hopkins

Psychology Faculty Research

A number of factors have been proposed to influence within and between species variation in handedness in non-human primates. In the initial study, we assessed the influence of grip morphology on hand use for simple reaching in a sample of 564 great apes including 49 orangutans Pongo pygmaeus, 66 gorillas Gorilla gorilla, 354 chimpanzees Pan troglodytes and 95 bonobos Pan paniscus. Overall, we found a significant right hand bias for reaching. We also found a significant effect of the grip morphology of hand use. Grasping with the thumb and index finger was more prevalent in the right …

Does Activating The Need To Belong Alter Things Important For Happiness And What Makes Life Complete?, Justus Rui Hao Wee

Dissertations and Theses Collection (Open Access)

Past research on the need to belong in groups has largely examined the circumstances under which individuals go against their personal preferences and conform to group norms. The current research examines how the need to belong may shape the things people view as important for happiness, and what makes their lives complete. Two studies tested the main hypothesis that after activating belongingness needs, participants will be more likely to emphasize the importance of things valued by society (e.g., a lot of money, a successful career, etc.). In Study 1, the need to belong was activated by asking participants to recall …

Improved Cardiorespiratory Fitness Is Associated With Increased Cortical Thickness In Mild Cognitive Impairment, Katherine Reiter, Kristy A. Nielson, Theresa J. Smith, Lauren R. Weiss, Alfonso J. Alfini, J. C. Smith

Psychology Faculty Research and Publications

Cortical atrophy is a biomarker of Alzheimer’s disease (AD) that correlates with clinical symptoms. This study examined changes in cortical thickness from before to after an exercise intervention in mild cognitive impairment (MCI) and healthy elders. Thirty physically inactive older adults (14 MCI, 16 healthy controls) underwent MRI before and after participating in a 12-week moderate intensity walking intervention. Participants were between the ages of 61 and 88. Change in cardiorespiratory fitness was assessed using residualized scores of the peak rate of oxygen consumption (V̇O_2peak) from pre- to post-intervention. Structural magnetic resonance images were processed using FreeSurfer v5.1.0. …

Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet

Research Collection School of Social Sciences

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that …
