Stress Profile Influences Learning Approach In A Marine Fish, Vincent Raoult, Larissa Trompf, Jane E. Williamson, Culum Brown

Personality Collection

The spatial learning skills of high and low stress juvenile mulloway (Argyrosomus japonicus) were tested in a dichotomous choice apparatus. Groups of fish were formed based on background blood cortisol levels and required to learn the location of a food reward hidden in one of two compartments. Low stress fish characterised by low background levels of the stress hormone cortisol had higher activity levels and entered both rewarded and unrewarded rooms frequently. Within the first week of exposure, however, their preference for the rewarded room increased, indicative of learning. Fish that had high background levels of cortisol, in …

Using Conditioned Place Preference To Investigate Changes In The Rewarding Effects Of Running And Eating Following Activity-Based Anorexia, Daniella Plaksiy

Theses and Dissertations

We used conditioned place preference to investigate whether activity-based anorexia would enhance the rewarding effects of running, causing running to be more rewarding than eating. We found that food restricted mice showed a clear preference for the food-associated chamber, and a subset of activity-based anorexia mice preferred the wheel-associated chamber.

Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris

Thesis Projects

Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment …

Dominance And Leadership: Useful Concepts In Human-Horse Interactions?, Elke Hartmann, Janne W. Christensen, Paul Mcgreevy

Animal Training and Obedience Collection

Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have been reported to be higher than in their feral counterparts but can often be attributed to suboptimal management. Horse owners often express concerns about the risk of injuries occurring in group-kept horses, but these concerns have not been substantiated by empirical investigations. What has not yet been sufficiently addressed are human safety aspects related to approaching and handling group-kept horses. Given …

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Grooming As An Agonistic Behavior In Garnett’S Small-Eared Bushbaby (Otolemur Garnettii), Jennie L. Christopher

Master's Theses

Social behaviors are a necessary component of group living and interactions between organisms. To correctly assess social interactions, researchers must be able to observe behaviors and interpret their function based on the behavior or the behavioral context. In primate species, grooming is often used to assess affiliations between group members and the consensus has been to always interpret grooming as an affiliative behavior. However, a number of avian, rodent and feline species have been shown to groom conspecifics aggressively. These instances of aggressive grooming appear most often when individuals are required to maintain close proximity to one another, such as …

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …

Pragmatic Understanding Of Bottlenose Dolphins (Tursiops Truncatus) Use Of A Two-Way Communication System, Pepper Reid Hanna

Dissertations

Pragmatics focuses on how a communication system is used to achieve a communicative goal, the social context of the communication, and the organizational structure of communications (Horn & Ward, 2004; McLaughlin, 1998). There is evidence of pragmatics within animal communication systems. For example, context appears to be an important component in both signal production and a receiver’s response in vervet monkeys (Seyfarth et al. 1980).

MA Thesis: http://aquila.usm.edu/masters_theses/170/

The current study used an underwater keyboard to establish a two-way communication system between humans and dolphins. The purpose of this study was to determine if, under these conditions, dolphins displayed pragmatic …

Identifying Behavioral Response Trends Following Aggression In Bottlenose Dolphins (Tursiops Truncatus), Breanna M. Cheri

Honors Theses

In group-living species, an individual’s response to aggression from another animal can reveal information about the complexities of their social relationships. The current study sought to categorize behavioral responses between conspecifics following direct aggression. Agonistic behavioral interactions were analyzed in a semi-captive group of bottlenose dolphins housed at the Roatan Institute for Marine Sciences, whose population dynamics mirror those observed in the wild. Interactions began at the onset of an aggressive behavior, and all concomitant behaviors between aggressor(s) and recipient(s) were coded chronologically for the length of each event. Results revealed five response types present following aggression: retaliation, reconciliation, avoidance, …

The Social Progression Of Post -Traumatic Stress Disorder: Post Vietnam And September 11th Attacks, Ellie Mcdonald

Capstone Projects and Master's Theses

The Social Progression of Post-Traumatic Stress Disorder Post-Vietnam and September 11^th Attacks is an examination on the infrastructure of the U.S. Department of Veterans Affairs’and of the Department of Defense’s lack of clarity and misinformation of the challenges and effects of mental illness within military ranks. Post-traumatic stress disorder (PTSD) made the Diagnostic Statistical Manual (DSM) after Vietnam. Since then, PTSD has been reevaluate numerous times, to properly define it. This research is a comparative analysis of the misconceptions of PTSD as experienced by Vietnam veterans and the first responders of the September 11^th tragedy. My research charts …

Culture Of Gentleness: A Behavioral Approach, Stevie Parcell

Honors Theses

The purpose of this paper is to explain the fundamentals of an ideological framework for caregivers providing services to people with disabilities called a Culture of Gentleness. The material is traditionally taught within the two-day Working with People training, and the efforts to spread this theory is headed by the Center for Positive Living Supports located in Clinton Township, Michigan. The material is then analyzed through a behavior analytic perspective. Each segment of the initial training will be discussed through both a Culture of Gentleness and behavioral perspective, rooted in Applied Behavior Analysis. Although established in the practice of Positive …

Timmy's In The Well: Empathy And Prosocial Helping In Dogs, Emily M. Sanford

Psychology Honors Projects

Dogs can empathetically evaluate humans’ emotional states. However, whether dogs are motivated by empathy to provide help to humans in need is unclear. In this study, dogs’ behaviors were observed while their owner sat behind a door and either cried or hummed. Dogs that were more skilled at regulating their emotional stress responses and had stronger bonds with their owners were more likely to help those owners. This supports the theory that an empathetic response is only possible when an individual can suppress their own distress enough to focus on helping someone else.

Microglial Location, Morphology, And Cognitive Performance In Mold-Exposed Mice, Karen Marmon

Theses and Dissertations

We examined changes in brain microglia and cognitive performance following mold exposure and doxycycline administration. Neither mold nor doxycycline caused significant changes in microglial location or morphology. While greater numbers of microglia in control-treated mice were linked with improved performance, greater numbers in mold-treated mice were linked to memory impairments.

Effects Of Pre-Conditioning On Behavior And Physiology Of Horses During A Standardised Learning Task, Kate Fenner, Holly Webb, Melissa Starling, Rafael Freire, Petra Buckley, Paul D. Mcgreevy

Animal Training and Obedience Collection

Rein tension is used to apply pressure to control both ridden and unridden horses. The pressure is delivered by equipment such as the bit, which may restrict voluntary movement and cause changes in behavior and physiology. Managing the effects of such pressure on arousal level and behavioral indicators will optimise horse learning outcomes. This study examined the effect of training horses to turn away from bit pressure on cardiac outcomes and behavior (including responsiveness) over the course of eight trials in a standardised learning task. The experimental procedure consisted of a resting phase, treatment/control phase, standardised learning trials requiring the …

Human Head Orientation And Eye Visibility As Indicators Of Attention For Goats (Capra Hircus), Christian Nawroth, Alan G. Mcelligott

Social Cognition Collection

Animals domesticated for working closely with humans (e.g. dogs) have been shown to be remarkable in adjusting their behaviour to human attentional stance. However, there is little evidence for this form of information perception in species domesticated for production rather than companionship. We tested domestic ungulates (goats) for their ability to differentiate attentional states of humans. In the first experiment, we investigated the effect of body and head orientation of one human experimenter on approach behaviour by goats. Test subjects (N = 24) significantly changed their behaviour when the experimenter turned its back to the subjects, but did not take …

Thinking Chickens: A Review Of Cognition, Emotion, And Behavior In The Domestic Chicken, Lori Marino

Intelligence Collection

Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. At least some birds are now known to be on par with many mammals in terms of their level of intelligence, emotional sophistication, and social interaction. Yet, views of chickens have largely remained unrevised by this new evidence. In this paper, I examine the peer-reviewed scientific data on the leading edge of cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities in …

Issues In Reputation And Its Management, Williams D. Kareem

Bullion

ln the corporate world, reputation is seen as a major element of an organisation's provenance alongside and included in financial performance and innovation. Reputation has been, and will continue to play a very important role in the life of corporate bodies. Organisations, be it commercial, governmental or even non-profit will always need good reputation to maintain their corporate stability, stay competitive and also prosper. Good reputation is pivotal to acceptance and approval by organisations' diverse stakeholders, even when such organisations are operating in an adverse ethical environments (sometimes self-created), and would desire to sustain a positive reputation where possible.

Cross-Modal Recognition Of Familiar Conspecifics In Goats, Benjamin J. Pitcher, Elodie F. Briefer, Luigi Baciadonna, Alan G. Mcelligott

Recognition Collection

When identifying other individuals, animals may match current cues with stored information about that individual from the same sensory modality. Animals may also be able to combine current information with previously acquired information from other sensory modalities, indicating that they possess complex cognitive templates of individuals that are independent of modality. We investigated whether goats (Capra hircus) possess cross-modal representations (auditory–visual) of conspecifics. We presented subjects with recorded conspecific calls broadcast equidistant between two individuals, one of which was the caller. We found that, when presented with a stablemate and another herd member, goats looked towards the caller sooner and …
