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 …

Not So Different As Cats And Dogs: Companionship During The Covid-19 Pandemic, Shelly Volsche, Elizabeth Johnson

People and Animals: The International Journal of Research and Practice

COVID- 19 lockdown provided a unique, in situ opportunity to probe caretaker experiences of living with companion animals during a stressful event. We launched an online survey in the United States that included standard demographic questions, questions related to household structures, and 25 Likert scale questions that probed perceptions of whether and how respondents’ relationships changed during social isolation. This paper uses a subset of that data specific to dog and cat guardians. A principal components analysis and Mann-Whitney U test returned no significant differences between cat and dog guardians on three scales (Scale 1: Psychological Well-being, Scale 2: …

Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff

Animal Sentience

In the target article Crump et al. present 8 criteria to assess whether decapods experience pain. Four of these -- sensory integration, motivational trade-offs, flexible self-protection, and associative learning -- could be used to assess sentience in general. In this commentary I discuss difficulties with using these criteria to provide evidence of sentience in decapods, particularly if this evidence is to change public opinion and policies. These difficulties are lack of evidence, the potential to eventually explain the neurobiological basis of the behaviors chosen as criteria, thereby eliminating any explanatory work for sentience, and the reluctance to bring animals that …

Unresolved Issues Of Behavioral Analysis In Invertebrates, Charles I. Abramson, Paco Calvo

Animal Sentience

Crump et al. (2022) provide a framework for determining the presence of sentience in organisms. Their target article is interesting and thought-provoking, but it does not consider the many unresolved issues related to behavioral analysis – especially when it concerns invertebrates. We feel that no real progress can be made until such fundamental issues as the need for a consistent definition of conditioning phenomena, the lack of a generally accepted behavioral taxonomy, and the use of cognitive terms to explain invertebrate behavior are examined critically.

Ethnic Differences In The Way College Students Cope With Stress, Temavulane N. Motsa

Masters Theses

Stress is one of the key concerns for students and has also been labelled the highest factor impacting students’ academic performance in colleges. A student’s ability to adequately cope with their stressors could determine their academic success or failure. This study examined whether there are any ethnic differences in the way African American and Caucasian American Students cope with stress. Data were collected from Students at Eastern Illinois University which included 45 African American Students and 40 Caucasian American students. The results revealed no significant differences in the way Caucasian American and African American students cope with stress. This paper …

Motivated Science: What Humans Gain From Denying Animal Sentience, Uri Lifshin

Animal Sentience

Resistance to the idea that non-human animals are sentient resembles erstwhile resistance to the theory that the earth is not the centre of the universe, or that humans evolved from “apes”. All these notions are psychologically threatening. They can remind people of their own creatureliness and mortality and might make them feel guilty or uncertain about their way of life. An honest debate over animal sentience, welfare and rights should consider the human motivation to deprive animals of these things in the first place. I briefly review empirical evidence on the psychological function of denying animal minds.

Curarse En Salud: Mexican Curanderos In Mental Health, Angela Molina

Scripps Senior Theses

Also known as traditional folk healers, Curanderos’ name stems from the word “curar” which means “to heal” in Spanish. Curanderismo is the practice and Curanderos are the practitioners. Prior research has found there are significant barriers Latinx communities face when seeking mental health care in the U.S. Reasons include institutional barriers such as language, citizenship, and socio-economic status and cultural barriers such as lack of cultural competency by practitioners. Because of the holistic healing nature Curanderismo emphasizes, extensive research has been conducted to understand why these marginalized communities seek Curanderos’ treatment. Culture and psychopathology have a significant relationship because psychiatric …

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 …

Mental Health In Italy: Systems, Stigma, And Impact Of Covid-19, Charley Nyzio

CISLA Senior Integrative Projects

In 1978, Italy became the first European nation to radically change its mental healthcare system. Psychiatric hospitals were shut down, and a community-based publicly-funded system of mental healthcare took its place. This reform sought to restore dignity to those with mental illnesses through rehabilitation and increased participation in the community and daily activities. Though characteristics of marginalization and exclusion were relatively eliminated, covert stigmas surrounding mental illness remain a persisting problem. This review seeks to 1) evaluate the historical progression of mental health reform as well as the effectiveness of the current system of mental healthcare in Italy 2) explore …

The Combined Influences Of Race, Sexuality, And Gender On Perceptions Of Sexual Harassment, Courtney House

Honors Theses

The current research examines the perceptions of sexual harassment based on the influence of the victim’s gender, and the race of both the victim and the perpetrator, and perceiver’s feminist beliefs. By using vignettes (a brief description of an event), we manipulated a) the gender of the victim (man or woman), b) the race of the victim (POC or white), and c) the race of the perpetrator (POC or white). Our hypotheses were as follows: a) vignettes depicting same-sex harassment will be less in line with the definition of sexual harassment; b) vignettes portraying the victim as a woman of …

Racial And Gender Discrimination Predict Mental Health Outcomes Among Healthcare Workers Beyond Pandemic-Related Stressors: Findings From A Cross-Sectional Survey, Rachel Hennein, Jessica Bonumwezi, Max Jordan Nguemeni Tiako, Petty Tineo, Sarah R. Lowe

Department of Psychology Faculty Scholarship and Creative Works

Racial and gender discrimination are risk factors for adverse mental health outcomes in the general population; however, the effects of discrimination on the mental health of healthcare workers needs to be further explored, especially in relation to competing stressors. Thus, we administered a survey to healthcare workers to investigate the associations between perceived racial and gender discrimination and symptoms of depression, anxiety, posttraumatic stress, and burnout during a period of substantial stressors related to the COVID-19 pandemic and a national racial reckoning. We used multivariable linear regression models, which controlled for demographics and pandemic-related stressors. Of the 997 participants (Mean …

Posttraumatic Stress Disorder: Comparing Short-Term, Intensive Therapy To Traditional, Long-Term Therapy, Laura Gonzalez, Sean Kruckenberg

Electronic Theses, Projects, and Dissertations

ABSTRACT

Posttraumatic Stress Disorder (PTSD) is a mental health diagnosis that occurs following a traumatic event, and military veterans are at higher risk of exposure to hazardous or life-threatening situations that may result in psychological trauma. PTSD sufferers experience symptoms such as distressing memories, nightmares, flashbacks, hypervigilance, and heightened arousal. Individuals with PTSD also experience higher rates of depressive and substance use disorders, involvement with the justice system, and self-harm and suicide. Many agencies, such as the Department of Veteran’s Affairs (VA) provide treatment PTSD, however most programs experience dropout rates as high as 36%. Recent studies have shown that …

Sample comprised of thirteen individuals including students and teachers. Data coding and analyses resulted in a large number of open codes, and eleven axial code categories besides a selective code that gave a comprehensive summation of the research study …

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 …

Colombian Women’S Experiences Of Cosmetic Surgery And Its Relationship To Body Image, Austin Gonzalez-Randolph

Dissertations

The purpose of this study was to understand women’s experiences of cosmetic surgery and its effects on body image on women from the Colombian cities of Bogotá and Pereira. The participants of this study were women of Colombian descent, who reside in Colombia. This was done with the hopes of better understanding how culture impacts views on cosmetic surgery. Colombia appears to have a culture that is very enmeshed with cosmetic surgery. This study provides an initial exploratory and qualitative investigation into the perception of body image as it relates to cosmetic surgery among six young women living in Colombia; …

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 …

Social Context Influences On Behavior Of Carolina Chickadees, Brittany A. Coppinger

Doctoral Dissertations

This dissertation assesses fundamental social factors that drive variation in calling and other behaviors of experimental flocks of Carolina chickadees. Specifically, I tested how group member familiarity and group composition affected individual behavior. In addition, I performed a direct experimental test of the Social Complexity Hypothesis for Communicative Complexity, which states that groups that are more socially complex will communicate with greater signal complexity than groups that are less social complex. I consider complexity to be a combination of three factors: the number of parts in a system, the variation among the parts, and the variation in the way those …

Analysis Of A Rough-Toothed Dolphin (Steno Bredanensis) Introduction In A Human Care Setting, Lindsey Johnson

Dissertations

Rough-toothed dolphins are a rarely studied species of cetaceans found in temperate and tropical waters throughout the world. These dolphins live in fission-fusion societies and are highly social, swimming in tightly-packed and highly synchronized subgroups consisting of 2-10 individuals. The current study documents the introduction of a stranded calf into an existing population of six rough-toothed dolphins living in a human care setting. Specifically, recordings of vocal and non-vocal behaviors were analyzed across the four phases of the study: baseline, day of introduction, post-introduction, and follow-up. Whistles, a vocal signal associated with social contexts, increased from baseline to post-introduction phases …

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.

Everyday Memory In People With Down Syndrome, Yingying Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

Social Media & Negative Effects On Body Image, Jack Fechter

English Department: Research for Change - Wicked Problems in Our World

Since the beginning of the 2010’s, social media has grown to affect every aspect of our daily lives. With children using it earlier in their lives, they are getting mass exposure to societal ideals about what body type should be. This has negatively impacted adolescents’ view of body image, which has led to dissatisfaction with their own bodies. This leads to depressive symptoms and even in some cases suicide, which has gone up among adolescents in the past decade. The article that follows details how and why these issues occur, as well as solutions to fix them. These solutions discussed …

Attention In Social Anxiety Disorder And Depression: Insights From Evoked Brain Responses, Matt Judah

Publications and Presentations

Social anxiety disorder and depression are thought to involve biased attention. For example, social anxiety may be associated with paying more attention to negative facial expressions. Depression may be associated with less attention to reward. Such biases in attention are thought to maintain symptoms, such as negative thoughts and avoidance. The presentation will describe the history of research examining biased attention in social anxiety disorder and depression. The speaker will present research using evoked brain responses as a window to understanding biased attention. Implications for social anxiety disorder and depression, as well as treatment, will be discussed.

The Effect Of The Difference In The Perception Of Temperature Between Sexes On The Academic Performance Of Chapin High School Students, Tiffany V. Phan

Journal of the South Carolina Academy of Science

Mental performance and mental functions may be negatively affected by decreases in thermal comfort as a result of large differences in temperature. Additionally, females are seen to be less content with room temperatures and actually prefer rooms with higher temperatures in comparison to males. This investigation explored the potential effect that sex plays in thermal perception and the impact it may yield on academic performance within a high school population. It was hypothesized that female students would experience an increase in academic performance as the temperature increased while males would experience the opposite effect. A quasi-experimental approach was used to …

An Evaluation Of Wayfinding Abilities In Adolescent And Young Adult Males With Autism Spectrum Disorder, Yingying Yang, Weijia Li, Dan Huang, Wei He, Yanxi Zhang, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Background

Wayfinding refers to traveling from place to place in the environment. Despite some research headway, it remains unclear whether individuals with Autism Spectrum Disorder (ASD) show strengths, weaknesses, or similarities in wayfinding compared with ability-matched typically developing (TD) controls.

Method

The current study tested 24 individuals with ASD, 24 mental-ability (MA) matched TD (MA-TD) controls, and 24 chronological-age (CA) matched TD (CA-TD) controls. Participants completed a route learning task and a survey learning task, both programmed in virtual environments, and a perspective taking task. Their parents completed questionnaires assessing their children’s everyday wayfinding activities and competence.

Results

Overall, CA-TD …

Do You Copy? Post-Traumatic Stress Disorder, Auditory Processing, And Heart Rate Variability, Lyndsey Johnson

UNF Graduate Theses and Dissertations

Self -report measures used in PTSD research have the potential to limit the degree of symptom severity in military veterans, especially as there is often underreporting in this population (Kline, Falca-Dodson, Susner et al., 2010). Polyvagal Theory provides a framework assessing if physiological measures can tap into PTSD Symptomology (Porges, 1995). It is therefore hypothesized that lower scores on auditory processing tests will be positively correlated with higher scores on Stress and PTSD measures. Additionally, it is thought that lower scores on auditory processing tedts as well as higher scores on PTSD and Stress Measures will be positively correlated with …

Inside The Zoo: Captive Giraffes’ Changes In Social Ties Throughout Membership Variations, Morgan Paige Howard

UNF Graduate Theses and Dissertations

Many animals live in gregarious, fission-fusion societies where group size and composition are continually changing. Despite this, many studies have suggested that captive animals are capable of maintaining long term social bonds with others. In captive giraffes, effects on their social bonds during membership transitions have not been studied thoroughly, however, prior research does show that social bonds are a defining factor in non-captive animals. Captive giraffe social network patterns were investigated at the Jacksonville Zoo and Botanical Gardens using all occurrence behavioral data. Based on previous research, I hypothesized that when one of the individuals in the group was …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

Distractors As A Tool To Increase “Self-Control” In Pigeons (Columba Livia), Peyton Mueller

Theses and Dissertations--Psychology

In the successive delay-discounting task, all trials start with a stimulus to which a response results in a small amount of reinforcement (smaller-sooner). If no response is made, the stimulus changes and a response results in a larger reinforcer (larger-later). The purpose of this study was to examine the use of a non-reinforced distractor (a stimulus to which responding has no programmed consequence) as a method of increasing the proportion of larger-later (LL) choices in a successive delay-discounting task. Earlier research studying the use of distractors may have inadvertently associated the distractor with reinforcement. Four experiments were conducted and each …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

Electronic Theses and Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …
