A Poetic Call For And A Reflection And Commentary On Clarity, Understanding, Hope, Courage, And Compassion, Carroy U. Ferguson

Psychology Faculty Publication Series

Finding a published poem I had written as a teenager, titled “The Heavens Weep.” this article uses that poem as the basis for a commentary that reflects on the state of the world today (2026),  As a commentary, the article uses the poetic and metaphoric words in the poem as a relevant "reality check" for what is still going on today.  In essence, the commentary is about a call for Clarity, Understanding, Hope, Courage, and Compassion, or what I call Archetypal Energies, Higher Vibrational Energies that operate deep within our individual and collective psyches to creatively urge us to "see" …

The Effects Human Presence Has On Dolphins Within A Natural Lagoon Enclosure In Managed Care, Mario Martinez, Winter Saldaña

Posters - 2026

● Previous research looked into the overall behavior of dolphins in managed care using observations of location (Dudzinski & Hill, 2025).

● This study provides opportunities to investigate the effects of human presence on dolphin activity and space use (Lauderdale et al., 2022; Trone et al., 2005).

● Purpose - To determine if human presence affects dolphin behavior / spatial use of natural lagoon.

● H1: Dolphin clustering will be seen in the most Northern part of the lagoon and area associated with humans consistently (Melillo et al., 2009).

● H2: Higher activity levels will be observed during the “during” …

The Evolution Of Self-Awareness In Conscious Organisms, Robert A. Dielenberg

Journal of Conscious Evolution

Self-awareness in conscious organisms remains an enduring puzzle for philosophers and neuroscientists. This paper proposes a tripartite evolutionary model tracing its emergence through three sequential types: the sensory self (primitive egocentric, valence-tagged awareness of sensory states), the bodily self (external objectification of the body as a distinct entity, evidenced by mirror self-recognition in select species), and the cognitive self (internal objectification of the mind enabling recursive self-transformation). Adopting a monist framework, the model treats consciousness as the biological substrate of delayed neural apperception (the “Delayed Present”), within which selves emerge as increasingly sophisticated models. It distinguishes non-human metacognition—implicit, online regulation—from …

Humanity Is Evolving Its Consciousness: The Role Of Archetypal Energies As Guides During An Unfolding Weeding Out And Alignment Process, Carroy U. Ferguson

Psychology Faculty Publication Series

Humanity is evolving its consciousness at individual and collective levels.  Given these seemingly tumultuous times, as of this writing (January 2026), to make such a statement may sound like a strange thing to say.  However, I suggest that if you are alive today and if you are reading these words, these are the very times for which you were born—to assist Humanity as it evolves its consciousness with your unique gifts, whatever they may be.  That is, this period of our individual and collective human being-ness may be characterized as an unfolding period of weeding out and alignment with the …

Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski

Theses and Dissertations (Comprehensive)

This thesis addresses how animals cope with unpredictability by testing how environmental stability changes the behaviour of zebrafish (Danio rerio) in two complementary experiments. In Experiment 1, fish lived for three months in either a Dynamic environment (water temperature, feeding times, habitat complexity, group size, and membership fluctuated) or a Stable environment (all factors constant). Across seven behavioural assays, measuring individual behavioural differences, collective movement, social memory, and information use, Dynamic condition fish were found to be more sensitive to social cues and more likely to conform to recent social information, independent of the quality of the information …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

Severe Aggression Among Zoo-Housed Coconut (Trichoglossus Haematodus) And Rainbow (Trichoglossus Moluccanus) Lorikeets: Wellbeing Considerations For Free-Flight Aviaries, Emily Simkins

UNF Graduate Theses and Dissertations

As conservation and education institutions, modern zoos balance the needs of animals with the interests of visitors through several strategies which can increase animal wellbeing and improve visitor experience. Environmental enrichment is frequently employed to increase the suitability of anthropogenic environments for zoo-housed animals, such as through walkthrough habitats and free-flight aviaries. While habitats such as these are important for visitor experience and can be enriching to animals, there are also wellbeing considerations for these spaces. Walkthrough habitats can be a potential source of fear and stress for animals, as shown by increased frequencies of vigilance, undesirable behavior, and aggression. …

Griffin's Slow Burn Revolution In Philosophy And Comparative Cognition, Kristin Andrews

Animal Sentience

Ristau presents Griffin as launching a scientific revolution supported by philosophical insights. This commentary focuses on two points: Griffin as a scientific revolutionary, although the cognitive ethology revolution is not yet complete; and on the immense influence Griffin had, and continues to have, on philosophy.

Can Animal Consciousness Be Resolved Scientifically?, Yoram Gutfreund

Animal Sentience

Carolyn Ristau's biography of Donald Griffin is a comprehensive work that sheds light on a seminal chapter in the history of ethology—the ambitious attempt to establish a research field dedicated to animal consciousness. Although Donald Griffin's endeavor ultimately fell short of its revolutionary goals, it catalyzed significant progress in understanding evolution and mechanisms of animal cognition.

Beyond Human Perception: The Remarkable Science Of Donald R. Griffin, Gareth Jones

Animal Sentience

Carolyn Ristau shows how Donald Griffin’s revolutionary science sometimes progressed from ridicule, to opposition, to being self-evident. Griffin’s work involved phenomena beyond human perception, making it sometimes difficult for others to fathom. His work on ultrasonic echolocation, navigation and animal cognition has shifted established paradigms. His ‘zoomorphic’ approach provides a realistic framework for understanding how other animals perceive the world.

Donald Griffin: A Visionary In Science And Consciousness, Brock Fenton

Animal Sentience

I share some reflections on a sabbatical with Donald Griffin a half-century ago, with fieldwork on bats and echolocating swiftlets in Australia and our discussions of animal behavior and consciousness. Griffin's influence has been vast, from recent advances in bat research, including learning, navigation, and longevity, to his enduring legacy as a pioneer in animal cognition.

Précis Of: "Birds, Bats And Minds: Tales Of A Revolutionary Scientist, Donald R. Griffin", Carolyn A. Ristau

Animal Sentience

Donald Griffin co-discovered bat sonar and founded the field of echolocation. He studied bird migration and founded Cognitive Ethology, the study of animal awareness and mental experiences. In all these endeavors, he faced hostile opposition. The biography (Ristau 2024) examines Griffin's life and the scientific explorations by him and others in these fields. This Précis emphasizes his arguments and supporting evidence for animal consciousness as well as his later research. Griffin considered the inhibiting assumptions made by scientists, including Cartesian views, the misunderstanding of innate behaviors, prejudice against lower animals, concern with violations of parsimony, and the assertions of the …

Complexities Of Consistent Individual Behavioral Differences In Effective Wildlife Management, Nathalie R. Sommer

Animal Sentience

The study of animal personality, or consistent individual behavioral differences, has faced numerous challenges since its inception, including terminological disputes, labor-intensive methodologies, and notable retractions. This commentary explores the mechanisms behind personality traits, questioning the link between personality and sentience, and highlights the bias towards megafauna in wildlife management. It underscores the ecological and ethical significance of considering arthropod personalities and the complexities of integrating personality into wildlife reintroductions. Caution is advised in generalizing personality effects, and the limitations of current measurement techniques are discussed, suggesting that personality traits should be one of many factors in comprehensive management strategies.

Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere

Animal Sentience

For many animal species, the ability to adapt to coexistence with the human species and to the environmental changes that humans cause is a biological imperative. This adaptive capacity varies not only between species, but within species. Studying individual differences in animals’ behavioral, cognitive and physiological adaptability is important for integrating ethology and conservation. Findings about animal cognitive capacities, including learning, need to be applied in conservation—but humans need to be educated about ethology, coexistence and conservation too.

Animal Personality And Sentience As Distinct Concepts, Mark Briffa

Animal Sentience

Owens et al (2024) discuss how knowledge of both animal personality and sentience in target populations can be leveraged to enhance wildlife conservation programmes. In this commentary I expand on the distinction between these two concepts. Behavioural differences should be considered broadly across conservation programmes, not just those involving species deemed sentient.

Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.

Animal Sentience

The lack of research on fish welfare highlighted by Oldfield & Bonano (2024) is only part of a more general problem: a relative neglect of animals other than mammals and birds. The causes are our lack of knowledge, our negative view of what we consider to be “lower” animals and our underestimation of their intelligence and sensitivity. Our estimation will increase as our knowledge increases. As a broader view spreads to the public through the media, it should gradually increase the demand to expand both research and welfare, especially beyond mammals and birds.

Social Interaction, Social Cognition, And Personality In Gartersnakes And Ball Pythons, Morgan Skinner

Theses and Dissertations (Comprehensive)

Snakes are often considered non-social animals. However, this is mostly an untested assumption and the limited research that has been done has shown that snakes interact socially when given the opportunity. Here, the complexity of snake social interactions was explored through a social cognition and personality lens. Group and individual behavioural assays were used to explore flexibility and consistency in social interactions. The results provide evidence that elucidate the function, development, and evolution of these behaviours in snakes. In the first experimental chapter, chapter 2, social network analysis was used to provide a detailed description of aggregation behaviour in 4 …

Animal Communication And Sentience, Catia Correia-Caeiro, Katja Liebal

Animal Sentience

Segundo-Ortin & Calvo (S&C) argue for sentience in plants on the basis of several studies of what they describe as "cognitive abilities" in plants. As other commentaries (e.g., Brooks Pribac, 2023; Damasio & Damasio, 2023; ten Cate, 2023) have pointed out, however, there is some misuse of several concepts, and a lack of evidence for sentience. We try to clarify three questions in S&C’s discussion: (1) How is communication defined and conceptualised in animal research? (2) Is plant communication comparable to animal communication? (3) Is communication (or the process we see in plants) a good basis for inferring sentience in …

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 …

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 …

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 …

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 …

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.

Sequential Analysis Of Livestock Herding Dog And Sheep Interactions, Jonathan Early, Jessica Alders, Elizabeth R. Arnott, Claire M. Wade, Paul Mcgreevy

Interactive Behavior Collection

Livestock herding dogs are crucial contributors to Australian agriculture. However, there is a dearth of empirical studies of the behavioural interactions between dog and livestock during herding. A statistical approach that may reveal cause and effect in such interactions is lag sequential analysis. Using 48 video recordings of livestock herding dogs and sheep in a yard trial competition, event-based (time between behaviours is irrelevant) and time-based (time between behaviours is defined) lag sequential analyses identified several significant behavioural interactions (adjusted residuals greater than 2.58; the maximum likelihood-ratio chi-squared statistic for all eight contingency tables identified all sequences as highly significant …

Social Learning In Solitary Juvenile Sharks, Catarina Vila Pouca, Dennis Heinrich, Charlie Huveneers, Culum Brown

Social Behavior Collection

Social learning can be a shortcut for acquiring locally adaptive information. Animals that live in social groups have better access to social information, but gregarious and nonsocial species are also frequently exposed to social cues. Thus, social learning might simply reflect an animal's general ability to learn rather than an adaptation to social living. Here, we investigated social learning and the effect of frequency of social exposure in nonsocial, juvenile Port Jackson sharks, Heterodontus portusjacksoni. We compared (1) Individual Learners, (2) Sham-Observers, paired with a naïve shark, and (3) Observers, paired with a trained demonstrator, in a novel foraging task. …

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), …

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 …

Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff

Animal Sentience

Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.

Moral Relevance Of Cognitive Complexity, Empathy And Species Differences In Suffering, John Lazarus

Animal Sentience

I qualify two criticisms made by commentators on Chapman & Huffman’s target article. Responding to the view that differences between humans and other animals are irrelevant to deciding how we should treat other species, I point out that differences between any species in their capacity to suffer are morally relevant. And in response to the claim that suffering is the sole criterion for the moral treatment of animals, I argue that cognitive complexity and a capacity for empathy also have moral relevance to the extent that they influence suffering.
