Practical Considerations For Conducting Canine Behavioral Science, Lucrezia Lonardo, Madeline H. Pelgrim, Jeffrey R. Stevens
Practical Considerations For Conducting Canine Behavioral Science, Lucrezia Lonardo, Madeline H. Pelgrim, Jeffrey R. Stevens
Jeffrey Stevens Publications
Research on behavior in domestic dogs (Canis familiaris) has increased rapidly recently due to the interest in them as pets, working dogs, and model species for understanding evolution, domestication, and even human health. This interest in canine behavioral science has resulted in the creation of dozens of dog lab worldwide, with more starting every year. Our aim here is to review practical issues that potential dog researchers might consider when deciding how to set up a dog lab and conduct research in canine behavioral science. We hope that this can offer a path forward in promoting high-quality, cutting-edge …
Adapting To Uncertainty: Effects Of Environmental Instability On Zebrafish Behaviour, Britney Sekulovski
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 …
Cephalopod Consciousness: Asking The Right Questions, Gordon Burghardt
Cephalopod Consciousness: Asking The Right Questions, Gordon Burghardt
Animal Sentience
Jennifer Mather has provided a comprehensive and fascinating overview of the various cognitive accomplishments of cephalopods and their sensory, behavioral, and neurophysiological attributes. The advances in our understanding of a clade that has been separated from vertebrate evolution by well over half a billion years is a testament to advances in both methodology and the questions we now feel free to address. Mather embeds her review in the issue of consciousness, which is certainly a perennial issue in mental evolution, going back to Romanes and earlier. I argue that the term “consciousness” has such a checkered history and is used …
Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave
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
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
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
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.
The Utilization Of String Pulling To Determine Female Rats' Dual Cognitive Motor Task Performance Following Space Flight Stressor Exposure, Doc-Haden Rodgers, Nicole M. Atttallah, Teresa L. Garcia, Nuhamine A. Moges, N. A. Moges, K. D. Omengan, J. F. Cortez, K. S. Dhede, A. A. Blackwell
The Utilization Of String Pulling To Determine Female Rats' Dual Cognitive Motor Task Performance Following Space Flight Stressor Exposure, Doc-Haden Rodgers, Nicole M. Atttallah, Teresa L. Garcia, Nuhamine A. Moges, N. A. Moges, K. D. Omengan, J. F. Cortez, K. S. Dhede, A. A. Blackwell
Undergraduate Research Symposium Posters
During deep space exploration, astronauts depend on mission-essential performance in Dual Cognitive Motor Tasks (DCMT), such as receiving information from ground control to assemble and configure wires during a spacewalk. DCMT relies upon processing cognitive and motor information simultaneously. Previous research on rodent models has shown various impairments in cognition and motor function in separate tasks after exposure to deep space radiation and sleep fragmentation (SF). However, an assessment of DCMT performance in rodents has not been established. Rats and humans use similar hand-over-hand movements to pull a string, and task demands may be varied to assess cognition and motor …
The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell
The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell
Undergraduate Research Symposium Posters
Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …
The Effects Of People, Time Of Day, And Season On Affiliative And Stereotypic Behaviors In Captive Rhinoptera Bonasus And Other Rays Across Two Human-Interactive Enclosures, Wren C. A. Newman
Theses and Dissertations
Cownose rays (Rhinoptera bonasus) are among the most common species found in aquaria, yet the impact of touch enclosures on their welfare remains largely unknown. While research on animal-visitor interactions has produced mixed results for other species, the lack of studies focusing on fish welfare poses a risk of overlooking potential welfare concerns. Therefore, we aimed to establish a baseline for cownose rays regarding stereotypic behaviors, sociality, and activity in captivity, and to examine the influence of human interaction on these behaviors. We collected over 700 hours of footage from two enclosures at Adventure Aquarium in Camden, NJ …
Animal Personality And Sentience As Distinct Concepts, Mark Briffa
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.
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Animal Sentience
Carolyn Ristau’s trilogy provides a comprehensive account of Donald Griffin’s life and work, with the third volume focusing on cognitive ethology. This commentary focuses primarily on my own interactions with Don, particularly during my sabbatical at Rockefeller University when his campaign for cognitive ethology was gaining momentum. I recount my research on reptile behavior and cognition, my collaboration with Don and others at RU, and my role in advancing his ideas while contextualizing them within 19th-century comparative psychology. I also discuss developments in cognitive ethology, including critical anthropomorphism, the challenges of integrating subjective experience into behavioral science, and Griffin’s lasting …
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
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.
Social Interaction, Social Cognition, And Personality In Gartersnakes And Ball Pythons, Morgan Skinner
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 …
Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.
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.
Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera
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 …
Between Choice And Compulsion: An Examination And Critique Of The Evolution Of 'Original Sin', Matthew James Wynn
Between Choice And Compulsion: An Examination And Critique Of The Evolution Of 'Original Sin', Matthew James Wynn
Graduate Theses/Dissertations
“Why are we the way that we are?” is one of the hardest questions to answer because it requires grasping the origin of human beings. This has left philosophers and theologians in century-long debates on forming a “cosmogony of ontology” (i.e., how the origin of the universe informs the human condition). The concept, “original sin” was developed by a North African theologian named Augustine (354 – 430 CE). Augustine’s reading of Genesis 3, and inaccurate translation of Romans 5:12, taught that a person is born morally culpable for a fault antecedent to their existence. This way of thinking about the …
Effects Of Social Context On Salivary Cortisol And Attention In Tufted Capuchins (Cebus [Sapajus] Apella), Andrew Desana
Effects Of Social Context On Salivary Cortisol And Attention In Tufted Capuchins (Cebus [Sapajus] Apella), Andrew Desana
Master’s Theses
Social context alters cognitive performance, but the mechanisms for this remain unclear. One possibility is that stressors associated with social contexts mediate changes in cognitive performance by influencing attention. We conducted two experiments to investigate how social context affects performance on an attention task in capuchin monkeys (Cebus [Sapajus] apella). We additionally validated and measured physiological stress through salivary cortisol. In experiment one, capuchins were exposed to three conditions where they were either isolated or paired with an affiliative or agonistic social partner separated by a barrier. In experiment two, subjects received affiliative and agonistic conditions without barriers to allow …
Chimpanzee (Pan Troglodytes) Skin Temperature During Resting Behavior At Different Ambient Temperatures, Benjamin Lake
Chimpanzee (Pan Troglodytes) Skin Temperature During Resting Behavior At Different Ambient Temperatures, Benjamin Lake
All Master's Theses
Thermal imaging, as a tool in psychological research, has been used to distinguish mental states evoked by different environmental and social cues, with prior research across several species. Ambient temperature can affect the precision of the measures of body temperature, however, so we investigated a methodology for recording thermal imaging data in sanctuary-housed chimpanzees (Pan troglodytes) while they engaged in resting behavior across different ambient temperatures. Data were collected on 30 adult chimpanzees (16 females and 14 males) ranging in age from 21 to 53 years (Mage = 33.4 years, SD = 8.0). The chimpanzees lived in nine social groups …
Proximate And Ultimate Perspectives On Romantic Love
Proximate And Ultimate Perspectives On Romantic Love
The International Journal of Ecopsychology (IJE)
Romantic love is a phenomenon of immense interest to the general public as well as to scholars in several disciplines. It is known to be present in almost all human societies and has been studied from a number of perspectives. In this integrative review, we bring together what is known about romantic love using Tinbergen’s “four questions” framework originating from evolutionary biology. Under the first question, related to mechanisms, we show that it is caused by social, psychological mate choice, genetic, neural, and endocrine mechanisms. The mechanisms regulating psychopathology, cognitive biases, and animal models provide further insights into the mechanisms …

Student Published Works
Environmental enrichment provides mental stimulation and minimizes abnormal behaviors in captive animals. In captive chimpanzees, individual animals may vary in the ways in which they benefit from enrichment or use enrichment devices, so investigating nuances in enrichment use may improve the welfare of captive chimpanzees. In the current study, three ethograms measuring distinct features of enrichment use (i.e., enrichment object, manipulation behavior, and social context) were evaluated by coding videos of captive chimpanzees (Pan troglodytes) at Chimpanzee Sanctuary Northwest in Cle Elum, WA. A total of 732 min and 58 s of video footage was coded from a larger video …

Psychology Faculty Publications
Wolf spiders within the genus Schizocosa have become a model system for exploring the form and function of multimodal communication. In terms of male signaling, much past research has focused on the role and importance of dynamic and static visual and substrate-borne vibratory communication. Studies on S. retrorsa, however, have found that female-male pairs were able to successfully mate in the absence of both visual and vibratory stimuli, suggesting a reduced or non-existent role of these signaling modalities in this species. Given these prior findings, it has been suggested that S. retrorsa males may utilize an additional signaling modality during …

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik
Faculty Publications
While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same …
Caregivers’ Inclination To See Their Children As Psychological Agents And Its Antecedents: A Cross-Cultural Study Of Parental Bonding, Reflective Functioning, And Maternal Mind-Mindedness, Chun-Hao Chiu
Graduate Research Theses & Dissertations
This dissertation examined difference in maternal mind-mindedness among American mothers, Taiwanese mothers, and mothers who emigrated from Taiwan and had their first child in the United States (Taiwanese Immigrant Mothers). It also investigated relationships between maternal mind-mindedness and mothers’ bonding with their parents during early years and their general mentalizing abilities for these three groups of mothers. One hundred twenty-three American mothers (Mage = 33.33 years old; SD = 5.31), 129 Taiwanese mothers (Mage = 35.93 years old; SD = 4.05), and 105 Taiwanese Immigrant Mothers (Mage = 36.85 years old; SD = 4.42) participated in this study online, through …
Wild Animal Welfare, Clare Palmer, Peter Sandøe
Wild Animal Welfare, Clare Palmer, Peter Sandøe
Animal Sentience
Rowan et al’s article provides an overview of developments in the science of animal sentience and its links to animal welfare policy, especially regarding farm animals. But changing ideas of animal sentience and welfare are also important for managing wild and other free-living animals. We ask how the welfare of these animals differs from that of farmed animals, especially how the ability to make autonomous choices may matter. We suggest that more research into wild animal welfare is needed to make informed policy decisions, for example, about using animals in rewilding projects and choosing between policies of culling and fertility …

The ability to represent approximate quantities appears to be phylogenetically widespread, but the selective pressures and proximate mechanisms favouring this ability remain unknown. We analysed quantity discrimination data from 672 subjects across 33 bird and mammal species, using a novel Bayesian model that combined phylogenetic regression with a model of number psychophysics and random effect components. This allowed us to combine data from 49 studies and calculate the Weber fraction (a measure of quantity representation precision) for each species. We then examined which cognitive, socioecological and biological factors were related to variance in Weber fraction. We found contributions of phylogeny …
Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph
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
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 …
