Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

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 …

A Deeper Understanding Of Noise Effects On Cetaceans, Jason N. Bruck

Faculty Publications

Recent research with cetaceans under human care is illuminating just how dolphins are affected by human-made noise both in terms of their ability to cooperate as well as their ability to habituate to such noise. This research is providing granular detail to regulators assessing the problems associated with anthropogenic effects and is highlighting a role for behavior/cognition research in conservation.

A Quieter Ocean: Experimentally Derived Differences In Attentive Responses Of Tursiops Truncatus To Anthropogenic Noise Playbacks Before And During The Covid-19-Related Anthropause, Paige E. Stevens, Veda Allen, Jason N. Bruck

Faculty Publications

The effects of anthropogenic noise continue to threaten marine fauna, yet the impacts of human-produced sound on the broad aspects of cognition in marine mammals remain relatively understudied. The shutdown of non-essential activities due to the COVID-19-related anthropause created an opportunity to determine if reducing levels of oceanic anthropogenic noise on cetaceans affected processes of sensitization and habituation for common human-made sounds in an experimental setting. Dolphins at Dolphin Quest Bermuda were presented with three noises related to human activities (cruise ship, personal watercraft, and Navy low-frequency active sonar) both in 2018 and again during the anthropause in 2021 via …

Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack

Faculty Publications

Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …

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, …

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 …

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.

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 …

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 …

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.

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 …

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.

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.

Regional Differences In Wild North American River Otter (Lontra Canadensis) Behavior And Communication, Sarah Walkley

Dissertations

This study focuses on the vocalization repertoires of wild North American river otters (Lontra canadensis) in New York and California. Although they are the same species, these two established populations of river otters are separated by a significant distance and are distinct from one another. River otters are semi-aquatic social predators that can be found throughout North America. This is the first study to examine the vocalizations of wild river otters, and results are compared across field sites in the different regions. River otter vocalizations and behaviors in New York were recorded using Bushnell Aggressor trail cameras that …

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 Referencing In The Domestic Horse, Anne Schrimpf, Marie-Sophie Single, Christian Nawroth

Recognition Collection

Dogs and cats use human emotional information directed to an unfamiliar situation to guide their behavior, known as social referencing. It is not clear whether other domestic species show similar socio-cognitive abilities in interacting with humans. We investigated whether horses (n = 46) use human emotional information to adjust their behavior to a novel object and whether the behavior of horses differed depending on breed type. Horses were randomly assigned to one of two groups: an experimenter positioned in the middle of a test arena directed gaze and voice towards the novel object with either (a) a positive or (b) …

Musical Dogs: A Review Of The Influence Of Auditory Enrichment On Canine Health And Behavior, Abigail Lindig, Paul Mcgreevy, Angela Crean

Stress Collection

Music therapy yields many positive health outcomes in humans, but the effects of music on the health and welfare of nonhuman animals vary greatly with the type of music played, the ethology of the species, and the personality and learning history of individual animals. One context in which music therapy may be used to enhance animal welfare is to alleviate stress in domestic environments. Here, we review studies of the effects of music exposure on dogs as a case study for the implementation of music therapy in veterinary medicine. Nine reports of experimental testing for the therapeutic effects of music …

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. …

Whether Invertebrates Are Sentient Matters To Bioethics And Science Policy, Michael L. Woodruff

Animal Sentience

Mikhalevich & Powell provide convincing empirical evidence that at least some invertebrates are sentient and hence should be granted moral status. I agree and argue that functional markers should be the primary indicators of sentience. Neuroanatomical homologies provide only secondary evidence. Consensus regarding the validity of these functional markers will be difficult to achieve. To be effective in practice, functional markers of sentience will have to be tested and accepted species by species to overcome the implicit biases against extending moral status to invertebrates.

The Question Of Animal Awareness, Francoise Wemelsfelder

Françoise Wemelsfelder, PhD

The problem of animal awareness lies at the interface of science and philosophy. As a starting point for the study of phenomena such as awareness, mind, consciousness, etc., we hardly have any reference other than our own human experience and in the context of a nondualistic ontology this can be justified. In philosophy and psychology it appears to be very difficult to give direct operational definitions of terms such as consciousness, etc. So we might expect this to be even more difficult in the study of animals. A detailed knowledge of animals and their behaviour is necessary in order to …

Animal Boredom: Is A Scientific Study Of The Subjective Experiences Of Animals Possible?, Françoise Wemelsfelder

Françoise Wemelsfelder, PhD

The aim of this paper is to explore the relationship between different meta-scientific frameworks and the science of animal welfare. Animal Boredom 117 During the past few years, I have become more and more convinced that the great difficulty science has in studying subjective experience in its objects, might be related to the denial of any role to subjective experience in the observer as an interpretational guide. Can a quality in the world around us be observed, when this same quality is deliberately excluded from the process of observing?

As a practical example for the discussion described above, the phenomenon …

Impact Of Stress, Fear And Anxiety On The Nociceptive Responses Of Larval Zebrafish, Javier Lopez-Luna, Qussay Al-Jubouri, Lynne U. Sneddon

Lynne Sneddon, PhD

Both adult and larval zebrafish have been demonstrated to show behavioural responses to noxious stimulation but also to potentially stress- and fear or anxiety- eliciting situations. The pain or nociceptive response can be altered and modulated by these situations in adult fish through a mechanism called stress-induced analgesia. However, this phenomenon has not been described in larval fish yet. Therefore, this study explores the behavioural changes in larval zebrafish after noxious stimulation and exposure to challenges that can trigger a stress, fear or anxiety reaction. Five-day post fertilization zebrafish were exposed to either a stressor (air emersion), a predatory fear …

Hpi Reactivity Does Not Reflect Changes In Personality Among Trout Introduced To Bold Or Shy Social Groups, Jack S. Thomson, Phillip C. Watts, Tom G. Pottinger, Lynne U. Sneddon

Lynne Sneddon, PhD

Physiological stress responses often correlate with personalities (e.g., boldness). However, this relationship can become decoupled, although the mechanisms underlying changes in this relationship are poorly understood. Here we quantify (1) how an individual’s boldness (response to novel objects) in rainbow trout, Oncorhynchus mykiss, changes in response to interactions with a population of either bold or shy conspecifics and we (2) measured associated post-stress cortisol levels. Initially-bold trout became shyer regardless of group composition, whereas shy trout remained shy demonstrating that bold individuals are more plastic. Stress-induced plasma cortisol reflected the original personality of fish but not the personality induced …

Do Painful Sensations And Fear Exist In Fish?, Lynne U. Sneddon

Lynne Sneddon, PhD

The detection of pain and fear in fi sh has been subject to much debate and, since fi sh are a popular experimental model and commercially important in both angling and aquaculture, many procedures that fi sh are subjected to cause injury, fear and stress. These injuries would give rise to the sensation of pain in humans but whether fi sh have the capacity for pain is relatively under explored. Recent evidence has shown that fi sh have the same neural apparatus to detect pain that mammals and humans do, that their brain is active during a potentially painful experience, …

Social Assemblages And Mating Relationships In Prairie Dogs: A Dna Fingerprint Analysis, Steven E. Travis, Con Slobodchikoff, Paul Kefan

Con Slobodchikoff, PhD

Mating system characterizations have been hindered by difficulties in accurately assigning parentage to offspring. We investigated the relationship between social assemblages and mating relationships in a territorial harem polygynous mammal, the Gunnison's prairie dog, using a combination of behavioral and molecular analyses. We demonstrate multiple paternity and an extraordinarily high incidence of extraterritorial fertilizations (i.e., 61% of all progeny), in combination with the existence of female kin groups. On this basis, we conclude that social assemblages alone provide a poor description of the Gunnison's prairie dog mating system, and suggest several potential reasons for the maintenance of territoriality in this …

Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert

Con Slobodchikoff, PhD

Geographic variation in alarm calls of Gunnison's prairie dogs (Cynomys gunnisoni) was analyzed at regional and local scales. Alarm calls in response to a common stimulus (the same human) were recorded at four colonies near Flagstaff, Arizona, and at six sites throughout the southwestern United States. The acoustic structure of calls was analyzed for seven call variables. Regional differences fit the prediction of greater differences with increased geographical separation. Differences between colonies at a local scale were not related to geographical distance, suggesting that local dialects exist within a region. Differences in the level of predation by humans …
