Neuroprotective Effects Of Prophylactic Brivaracetam On Memory And Anxiety Following Traumatic Brain Injury, Sofia Dumic

Theses and Dissertations

Prophylactic brivaracetam (BRV) was evaluated in a rat TBI model for effects on behavior and serum tau. BRV reduced anxiety-like behavior with optimal dose-dependent effects at 2.1mg/kg, but did not affect working memory. Serum tau was detectable early post-injury, supporting its use as a biomarker.

Inhibitory Control In Asian Elephants, Gillian Schmitt

Theses and Dissertations

Inhibitory control is defined as the ability to suppress a prepotent motor response in favor of a more efficient or advantageous behavior, and is an important core executive function. Although elephants are known to behave flexibly and display other executive functions, there is currently little information available on if, and to what extent, they display inhibitory control. We tested 16 captive Asian elephants (Elephas maximus) (N = 8 males, 8 females) ranging in age from 4-years-old to 60-years-old at the National Elephant Institute in Thailand using a classic detour paradigm adapted to be more ecologically salient for them through the …

Individual Differences In Wild Asian Elephant Behavior: Links Between Innovation And Responses To Novelty Across A Mosaic Landscape, Sarah L. Jacobson

Dissertations, Theses, and Capstone Projects

An animal’s responses to a novel or changing environment are influenced by a number of behavioral traits and cognitive abilities associated with flexible decision making. Animals also exhibit strong consistency in some behavioral responses, described as personality traits, which may influence their ability to adjust to environmental changes. It is important to investigate both flexibility and consistency in behavior, as well as how these two characteristics interact with each other, to understand the range of individual variation in behavior and decision making within a species. This knowledge can also help us understand how some species and individuals within a species …

Sex Differences In The Diets Of Forest-Dwelling Baboons (Papio Anubis), Kara Hartunian

Theses and Dissertations

The ability to eat and switch between many food sources is an adaptative feeding strategy utilized for meeting nutritional needs across different environments, seasons, and physiological conditions. Baboons (genus Papio) excel at both dietary flexibility and foraging selectively, and consequently have one of the most widespread geographic distributions in the Order. To further expand to our understanding of baboon feeding ecology, I analyzed foraging activity and the nutritional characteristics of the diets of the relatively understudied rainforest baboons (Papio anubis) living in Kibale National Park, Uganda. I also investigated if there are differences in food type choice …

Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan

Theses and Dissertations

Many studies have been conducted using a training paradigm based on the research of Pryor et al. (1969) wherein the participants are trained on the abstract concept: do something different. This paradigm challenges working memory and requires the participants to respond with a behavior, either previously trained or novel, which has not yet been offered within the session. The work of Braslau-Schneck (1994) expanded this concept and demonstrated the ability of dolphins to successfully complete this task in synchronized pairs, though the method of accomplishing this task remained unclear. The present research was conducted as part of a broader …

Teacher Beliefs And Experiences Addressing Healthy Racial And Ethnic Identity Instructionally Through Social Emotional Learning, Juliana Gutierrez

Theses and Dissertations

Children and youth develop within an ecological context that includes family, peers, and broader social environments including school. Children’s understanding of their ethnic or racial group and the meaning they attribute to belonging in that group is also shaped by interactions in their school environment. Most research on school-based social-emotional learning (SEL) programs has focused on student behavioral and academic outcomes. However, as SEL spreads across U.S. K-12 schools, questions have emerged surrounding how children from diverse racial and cultural groups and unequal opportunity can benefit from universal SEL programs. Using a mixed-methods design, this study explores teachers’ understanding and …

A Year As A Monk Parakeet, Eric Thompson

Theses and Dissertations

Monk parakeets are a species of parrot native to subtropical and temperate regions of Argentina, Brazil, Uruguay, Paraguay, and Bolivia that have been introduced to many parts of the world. Monk Parakeets have lived in Brooklyn, New York since the 1970s and many myths and legends surround how these birds came to live here. This thesis is a description of the behavior of monk parakeets in Brooklyn, New York’s Greenwood Cemetery based on observations I conducted twice a week from January through October of 2023. Because of the unusual nature of this population of parakeets as well as their unique …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera

Dissertations, Theses, and Capstone Projects

Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Voiding The Unwanted Self: An Examination Of Racialized Violence In The United States, Benjamin Stark

Dissertations, Theses, and Capstone Projects

This dissertation is concerned with the role of the psychic defenses projection and projective identification in the processes which lead to racialized violence in the United States. The dissertation posits that projection has been less considered as a primary driver of racialized violence than other psychic processes and should be better integrated into psychological research and literature on racialized violence. The thesis begins with a detailed examination of two instances of racialized violence, the first a macro example of nation vs. nation: the United States’ invasion of Iraq in 2003, before which the United States fantasized Iraq was developing weapons …

Confusion Of Tongues: Translation And Transfers Of Attachment In A Post-Monolingual Condition, Hiji Nam

Dissertations, Theses, and Capstone Projects

“Confusion of Tongues” proposes an intersubjective, dialogic approach to translation, psycholinguistics, and patient and clinicians’ relationships to the “mother tongue” and secondary languages. By tuning in to linguistic and translational shifts, stutters, and gaps, the study presents a consideration of the challenges and rewards presented by what I call a “post-monolingual clinical condition.” An individual’s self-state in a specific language will be shadowed by the emotional history and associations one brings to that language, which will also ripple into the counter-transferential matrix—we might call this the “transference to language,” or attachment styles that manifest and repeat an individual’s forgotten libidinal …

The Case Of The Disappearing Owner: Do Dogs Show Behavioral Evidence Of Violation Of Expectation?, Rita Kanagat

Theses and Dissertations

The What the Fluff challenge became a series of viral YouTube videos that started in 2018. In the videos, a person stood behind a blanket in a doorway in front of their dog and lifted and lowered the blanket revealing and obscuring themselves, and finally disappearing with a final blanket drop. The dogs’ reactions were varied but were suggestive of a violation of expectation response. We conducted a community science study that employed methodologies consistent with the What the Fluff Challenge paradigm that were conducted in the owners’ homes with their dogs. Each owner was required to run a control …

Gaze In Cats And Dogs, Michael Bogese

Theses and Dissertations

Domestic dogs (Canis lupus familiaris) developed many behaviors across domestication, one example being gaze behavior. Gaze is the crux of other behaviors that make dogs unique in human-animal dyads, including lookbacks, gaze-following, and participation in an oxytocin feedback loop. Gaze behavior may have been motivated and sustained by evergreen cooperative relationships between dogs and humans (e.g., hunting, service roles). One way to confirm this relationship is to compare dogs to a domesticated species that lacks a protracted history of companionship: the domestic cat (Felis catus). In this study, we compare the gaze duration to owners of …

Withdrawal From Voluntary Oral Methamphetamine Reveals Female Specific Susceptibilities To Behavioral Deficits And Neurochemical Perpetuators Of Neurotoxicity And Drug Seeking Behavior, Nicoletta K. Memos

Dissertations, Theses, and Capstone Projects

MA is a potent, highly addictive psychomotor stimulant known to produce neurotoxic effects on the brain leading to neurological impairments^1-6 characterized by neurodegeneration of dopaminergic fibers, cell bodies and pathways, as well as brain regions such as the hippocampus, frontal cortex, and midbrain^1,5.

In MA addiction, women are more vulnerable to the behavioral and cognitive effects of MA compared to men. Adult human literature reveals gender differences in usage patterns and women demonstrate increased vulnerability to the neurotoxic effects and health effects of MA use. Women begin drug use at an earlier age, escalate drug use quicker, …

Investigation Of Behavioral Responses Including Visual Side Biases To Social Stimuli In Bottlenose Dolphins (Tursiops Truncatus), Jennifer R. Savoie

Dissertations, Theses, and Capstone Projects

Cetacean field studies have reported consistent population-level side biases for foraging behaviors and this right side feeding bias is arguably the strongest in any species next to handedness in humans. Notably, experimental studies with cetaceans, particularly dolphins, have struggled to find laterality in other behaviors, and some have reported patterns that are inconsistent with those typically found in vertebrates. Side biases related to social processing have been reported in a few observational studies of wild delphinids but have not been successfully evaluated in a controlled experimental context. This dissertation investigated viewing side biases of bottlenose dolphins in two contexts: when …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

From Psychology To Phylogeny: Bridging Levels Of Analysis In Cultural Evolution, Mason Youngblood

Dissertations, Theses, and Capstone Projects

Cultural evolution, or change in the socially learned behavior of a population over time, is a fascinating phenomenon that is widespread in humans and present in some non-human animals. In this dissertation, I present an array of cultural evolutionary studies that bridge pattern and process in a wide range of research models including music, extremism, and birdsong. The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Environmental Cues And The Sociospatial Imaginary: An Examination Of Spatial Perception And Meaning-Making In A Gentrifying Neighborhood, Todd Levon Brown

Dissertations, Theses, and Capstone Projects

What could be more ordinary or pedestrian than two people walking down an urban street and talking about what we see and what we make of it? Yet this simple, quotidian act of walking a street—seeing, perceiving and experiencing physical spaces, places and objects—and making meaning of what is encountered, is the basis of my dissertation. It is also my basis for claiming that I have learned a great deal—and much unexpectedly—about how differently different people see and interpret the urban streetscape. What are the various environmental cues that stand out to different individuals? What are the psychosocial imaginaries that …

Investigating Social Preferences In A High Fission-Fusion Society Of Black And White Ruffed Lemur (Varecia Variegata), Patricia A. Adamo

Theses and Dissertations

Wild lemur primates were tested for social preferences across behaviors. Study found highly conservative social preferences that were very consistent across all behavioral states, despite high fission fusion traits common of lemur groups. This finding lays the foundation for using nearest-neighbor as a proxy of social preference for future endeavors.

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Tools For Thought: Artifacts From The History Of Comparative Psychology, Dylan Kerr

Theses and Dissertations

This project explores the history of comparative psychology through close readings of apparatuses used in seminal experiments on animal behavior, drawing connections between seemingly disparate areas of human culture—including art, architecture, mythology, and economics—and the development of the science, with a particular focus on behaviorist and cognitive approaches.

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

Some Non-Human Languages Of Thought, Nicolas J. Porot

Dissertations, Theses, and Capstone Projects

What might we learn if we take seriously the possibility of non-human Languages of Thought (LoT)? A LoT is a combinatorial set of mental representations. And, since mental representations and rules of combination vary in kind, there are many possible LoTs. Simple LoTs might lack familiar features of the putative human LoT, such as object representations, recursively defined rules of combination, sentential connectives, or predicate-argument structure. The most familiar arguments for the existence of LoTs, such as those from productivity, systematicity, concept learning, and perceptual computation, all fail when applied to non-human animals. But recent empirical evidence motivates attributing LoTs …

Exploring Innovation And Behavioral Flexibility In African Lions (Panthera Leo) And Snow Leopards (Panthera Uncia), Victoria L. O'Connor

Theses and Dissertations

Intelligence may have evolved to help animals problem-solve in their physical and/or social environments, which enables them to cope with changes in their environments. Humans can reduce wildlife conflict by understanding how species that face harsh environments assess a situation and alter their behavior. Tests for cognitive behavior aim to formulate clear behavioral criteria for inferring an animal’s mental processes. We designed a custom multi-access puzzle box (MAB) to present a simple and effective behavioral test for exploring innovation in two species, African lions (Panthera leo) and snow leopards (Panthera uncia). Despite being vastly underrepresented in …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

My Problems Are Solvable: Idiographic Methods Offset Age Differences In Interpersonal Problem Solving Among Young, Middle-Aged, And Older Adults, Daniele Artistico, Daniel Cervone, Carolina Montes Garcia

Publications and Research

This study tested the hypothesis that older adults retain high levels of everyday problem solving performance when confronting problems of maximal ecological relevance, identified through idiographic methods. Younger, middle-aged, and older adults completed a daily challenge questionnaire (DCQ) in which they reported problems of maximal personal relevance or idiographic problems. The large majority of the problems reported were interpersonal. We then assessed performance on an everyday problem-solving task in which participants generated solutions for idiographic problems as well as problems generated by group matched research participants representing each of two other age groups (e.g., older adults received their own problems …

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan

Theses and Dissertations

The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside of its …

Object Permanence In Asian Elephants (Elephas Maximus), Dalia Miller

Theses and Dissertations

This study investigated object permanence in Asian elephants (Elephas maximus) using visible and invisible test paradigms with single and multiple object displacements. Elephants were predicted to succeed, demonstrating a capacity for object permanence and for using vision in a cognitive task. Study outcomes supported these predictions.

Dolphins In Space: Quantifying The Relative Positions Of Bottlenose Dolphins (Tursiops Truncatus), Megan S. Mcgrath

Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) are socially sophisticated mammals with high fission-fusion dynamics and complex communication. The relative positioning of individual dolphins as they swim within their social group may aid in the expression of social roles. This study sought to quantify relative positioning in a small social group of female bottlenose dolphins at the National Aquarium in Baltimore that included two mother-daughter pairs, maternal and paternal half-sisters, a half-aunt and niece, and one unrelated female. We devised a method for scoring relative positioning in three dimensions. We found that the two mothers and their juvenile and adult daughters …

The Mediating Role Of Health Consciousness In The Relation Between Emotional Intelligence And Health Behaviors, Adriana Espinosa, Selma Kadic-Maglajlic

Publications and Research

The goals of this study were to identify groups of health-related behaviors among young adults (N = 314, Mage = 21.94, SD = 6.53), gauge the relation between emotional intelligence and health behaviors in this population, and assess health consciousness as mediator of said relation. Latent class analysis identified two mutually exclusive health behavior groups, which according to response patterns were labeled as Healthy and Unhealthy.The Healthy group(56%)was composed of individuals who had a healthy diet (i.e.,low fat and high fiber),exercised regularly,and who frequently engaged in behaviors that prevent oral and skin-related diseases. In contrast, the Unhealthy group (44%) rarely …
