First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith 2019 University of Southern Mississippi

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The first occurrence ...


Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor 2018 The University of Southern Mississippi

Using Personality Traits To Predict Pectoral Fin Contact Initiation Role In Bottlenose Dolphins (Tursiops Truncatus), Riley Paige Macgregor

Master's Theses

Contact with the pectoral fin facilitates formation and maintenance of social relationships between dolphins (Dudzinski & Ribic, 2017). Additionally, several studies have shown that bottlenose dolphins have distinct personalities that are consistent across time and situation (e.g., Highfill & Kuczaj, 2007; Kuczaj, Highfill, & Byerly, 2012), and it has been suggested that these individual differences (i.e., personality) may influence tactile behavior exchanges. The current study therefore aimed to determine if bottlenose dolphin personality traits predict whether and how dolphins initiate contact as a rubber or rubbee during pectoral fin contact exchanges, and to identify whether the effects of personality traits predicting initiator role varied across sex and age-class. Instances of pectoral fin contacts were selected from previously recorded underwater video observations of a bottlenose dolphin group under human care at the Roatan Institute for Marine Sciences (RIMS) between 2014 and 2017. Personality assessments were conducted by experienced trainers for dolphins using rating questionnaires that reflected the personality traits from the Five-Factor Model (i.e., Extraversion, Agreeableness, Openness to Experience, Conscientiousness, and Neuroticism; Goldberg, 1990). Multiple regression analyses suggested that personality traits do not fully predict initiator role; however, Conscientiousness and its interactions with sex and age may be important. Loglinear analyses showed Agreeableness affected the area of the body that was contacted when a rubbee initiated pectoral fin contact. This study demonstrates a first look at how personality influences the initiator side of pectoral fin contact exchange in bottlenose dolphins.


Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Monica Padilla de la Torre, Christian Nawroth 2018 Queen Mary University of London

Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Monica Padilla De La Torre, Christian Nawroth

Emotion

Emotions can be defined as an individual’s affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other’s emotional states, a process labeled as “emotional contagion.” Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective ...


Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth 2018 Leibniz Institute for Farm Animal Biology

Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth

Social Cognition

In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other reference persons can influence human–animal interaction at different levels and over different periods of time. In this study, we investigated human-directed behaviour in the ‘unsolvable task’ paradigm in two groups of domestic goats (Capra aegagrus hircus). One group was positively handled and habituated to a plastic box by the experimenter to retrieve a food reward, while the other group only ...


What To Do When Scalar Invariance Fails: The Extended Alignment Method For Multi-Group Factor Analysis Comparison Of Latent Means Across Many Groups [Accepted Manuscript], Herbert W. Marsh, Jiesi Guo, Philip D. Parker, Benjamin Nagengast, T. Asparouhov, Bengt Muthen, Theresa Dicke 2018 Australian Catholic University

What To Do When Scalar Invariance Fails: The Extended Alignment Method For Multi-Group Factor Analysis Comparison Of Latent Means Across Many Groups [Accepted Manuscript], Herbert W. Marsh, Jiesi Guo, Philip D. Parker, Benjamin Nagengast, T. Asparouhov, Bengt Muthen, Theresa Dicke

Faculty of Health Sciences Publications

Scalar invariance is an unachievable ideal that in practice can only be approximated; often using potentially questionable approaches such as partial invariance based on a stepwise selection of parameter estimates with large modification indices. Study 1 demonstrates an extension of the power and flexibility of the alignment approach for comparing latent factor means in large-scale studies (30 OECD countries, 8 factors, 44 items, N = 249,840), for which scalar invariance is typically not supported in the traditional confirmatory factor analysis approach to measurement invariance(CFA-MI). Importantly, we introduce an alignment-within-CFA (AwC) approach, transforming alignment from a largely exploratory tool into ...


Episodic-Like Memory In Dogs: Solving What-Where-When Tasks, Ka Ho Lo 2018 The University of Western Ontario

Episodic-Like Memory In Dogs: Solving What-Where-When Tasks, Ka Ho Lo

Electronic Thesis and Dissertation Repository

Episodic memory is a unique, personal memory that contains what happened, where it happened, and when it happened. Although episodic-like memory (ELM) in non-human animals has been shown using ­­what-where-when (WWW) memory paradigms, it has not previously been shown in dogs. Dogs are an excellent candidate for developing translational models of neurodegenerative disorders related to episodic memory, including Alzheimer’s disease. Dogs were tested on experiments that involved spatially and temporally unique odour sequences. Dogs were tested to see if they remembered the odours, their locations, and their time of presentation by choosing the earlier-exposed odour at the test. Findings ...


Examining The Different Learning Strategies Between Extroverts And Introverts Among Flight Students At Embry-Riddle Aeronautical University, John R. Brooks 2018 Embry-Riddle Aeronautical University

Examining The Different Learning Strategies Between Extroverts And Introverts Among Flight Students At Embry-Riddle Aeronautical University, John R. Brooks

National Training Aircraft Symposium (NTAS)

Extroverts and introverts have unique approaches to new materials that make learning more efficient. In fields like aviation, where quick learning and responses are required, students struggle because preferred comprehension strategies are not utilized. The research question is whether introverts/extroverts learn better when given the option to approach materials using strategies that match their personality type. A total of twenty-four participants from the Embry-Riddle Aeronautical University Flight Program will be chosen and placed into one of two different groups (extrovert/introvert) using a median split. The Eysenck Personality Questionnaire – Revised (EPQ-R) will determine personality trait (introvert or extrovert). All ...


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor 2018 The University of Southern Mississippi

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard (Gardner & Gardner, 1969; Rumbaugh, 1977; Savage-Rumbaugh, 1986). Savage-Rumbaugh decided to take a different approach to learning after one individual demonstrated the ability to use the keyboard ...


Inequity And Excellence In Academic Performance: Evidence From 27 Countries [Accepted Manuscript], Philip D. Parker, Herbert W. Marsh, John P. Jerrim, Jiesi Guo, Theresa Dicke 2018 Australian Catholic University

Inequity And Excellence In Academic Performance: Evidence From 27 Countries [Accepted Manuscript], Philip D. Parker, Herbert W. Marsh, John P. Jerrim, Jiesi Guo, Theresa Dicke

Faculty of Health Sciences Publications

Research suggests that a country does not need inequity to have high performance. However, such research has potentially suffered from confounders present in between-country comparative research (e.g., latent cultural differences). Likewise, relatively little consideration has been given to whether the situation may be different for high- or low-performing students. Using five cycles of the Programme for International Student Assessment (PISA) database, the current research explores within-country trajectories in achievement and inequality measures to test the hypothesis of an excellence/equity tradeoff in academic performance. We found negative relations between performance and inequality that are robust and of statistical and ...


It's Not Just A Dog: The Role Of Companion Animals In The Family's Emotional System, Cassandra Leow 2018 University of Nebraska - Lincoln

It's Not Just A Dog: The Role Of Companion Animals In The Family's Emotional System, Cassandra Leow

Public Access Theses and Dissertations from the College of Education and Human Sciences

Past studies have looked into the role of companion animals in families. This study intended to explore the role of companion animals in the family’s emotional system through the lens of Bowen Family Systems Theory. Data from a study on companion animal loss and grief were used. A qualitative phenomenological approach was adopted to analyze the data from interviews. Three primary themes emerged from the data: balanced family emotional system, response to relational anxiety and role of the absence companion animal. The first theme suggested that human family members and companion animals developed a balanced family emotional system through ...


Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. McElligott 2018 Queen Mary University of London

Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott

Social Cognition

Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall ...


An Analysis Of Innovate Training With Bottlenose Dolphins (Tursiops Truncatus), Raymond John Van Steyn 2018 CUNY Hunter College

An Analysis Of Innovate Training With Bottlenose Dolphins (Tursiops Truncatus), Raymond John Van Steyn

School of Arts & Sciences Theses

The National Aquarium in Baltimore, Maryland conducted a training program in 2014 to develop a gestural command for their dolphins called “innovate”. This training paradigm was developed to resemble the seminal research by Pryor, Haag and O’Reilly (1969), as well as more recent efforts of Braslau-Schneck (1993) and Kuczaj and Eskelinen (2014) of training dolphins to offer “creative” behaviors not developed through conventional methods of behavioral modification, such as shaping. The goal of the present study was to observe records taken during the National Aquarium’s training procedure as well as data collected ~3 years after said training in ...


Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth 2018 Agroscope Tänikon

Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth

Spatial Cognition

Horses’ ability to adapt to new environments and to acquire new information plays an important role in handling and training. Social learning in particular would be very adaptive for horses as it enables them to flexibly adjust to new environments. In the context of horse handling, social learning from humans has been rarely investigated but could help to facilitate management practices. We assessed the impact of human demonstration on the spatial problem-solving abilities of horses during a detour task. In this task, a bucket with a food reward was placed behind a double-detour barrier and 16 horses were allocated to ...


Evaluating Shame; A Comparative Look At Sexual And Physical Abuse, Kathryn McKenzie, Theresa Botts 2018 Eastern Kentucky University

Evaluating Shame; A Comparative Look At Sexual And Physical Abuse, Kathryn Mckenzie, Theresa Botts

Kentucky Journal of Undergraduate Scholarship

Shame is a potential adverse effect which can occur following a traumatic experience, such as being a survivor of sexual and physical abuse. Demonstrating the prevalence and levels of shame resulting from sexual and physical abuse can be of interest to those professionals working with survivors of trauma. The purpose of this study was to separately evaluate the prevalence of shame within sexual and physical abuse. This study tested the following hypotheses: hypothesis 1, shame will be more prevalent and demonstrate higher levels in sexual abuse survivors than in physical abuse survivors and hypothesis 2, survivors of both sexual and ...


The Conundrum Of Causal Reasoning In Elephants, Beri Brown 2018 The University of Southern Mississippi

The Conundrum Of Causal Reasoning In Elephants, Beri Brown

Master's Theses

Causal reasoning is marked by the ability to mentally reconstruct the missing part of a sequence in order to reproduce an outcome. While research on causal reasoning has been done with children, the results of the studies have been inconsistent. A standardized paradigm for comparative causal reasoning studies does not exist. Nissani (2006) investigated causal reasoning in a tool-use task with elephants and concluded that elephants were not capable of causal reasoning. The current study, a modified replication, yielded results that were not congruent with Nissani’s (2006) manuscript. Additionally, it was very unlikely that the Nissani (2006) study truly ...


Perceived Maternal Invalidation And Drinking Behavior: The Role Of Action Control, Elise Ann Warner 2018 University of Arkansas, Fayetteville

Perceived Maternal Invalidation And Drinking Behavior: The Role Of Action Control, Elise Ann Warner

Theses and Dissertations

Alcohol use disorder is one of the most prevalent disorders worldwide. As such, researchers have examined factors contributing to alcohol use. Perception of emotional experiences in childhood as invalidating by parents is one factor that has been found to predict later alcohol use, though less is known about maternal invalidation specifically. Parental invalidation has also been found to predict difficulty regulating affective states (i.e., negative and positive affect), which is also a determinant of alcohol use. Further, researchers have studied temptation to drink and restraint from drinking as related to alcohol use to better understand drinking behavior. Though there ...


Systems Of Quantity Judgment In Various Species: A Meta-Analysis, Tiffany A. Woodard Baker 2018 University of Southern Mississippi

Systems Of Quantity Judgment In Various Species: A Meta-Analysis, Tiffany A. Woodard Baker

Dissertations

An abundance of behavioral and neuroimaging literature supports the presence of two cognitive systems for quantity judgments (Agrillo & Bisazza, 2014). In particular, small quantities are thought to be guided by the object-file system, a precise system that uses mental files to map onto real world objects, and large quantities by the approximate number system, an imprecise, estimation system (Dehaene, 1997). Evidence supporting both systems exists in a variety of species including nonhuman primates (Boysen & Hallberg, 2000), birds (Garland, Low, & Burns, 2012), amphibians (Uller, Jaeger, Guidry, & Martin, 2003), and fish (Agrillo, Dadda, Serena, Bisazza, 2009), but support may depend on species ...


The Psychology Of Baseball: How The Mental Game Impacts The Physical Game, Kiera Dalmass 2018 University of Connecticut

The Psychology Of Baseball: How The Mental Game Impacts The Physical Game, Kiera Dalmass

Honors Scholar Theses

The purpose of this study was to find whether or not sports psychology can be effective. Baseball was chosen as the sport for the study because baseball can be analyzed for nearly every single factor of the game, with the exception of the mental readiness or state of the player when he steps onto the field. It therefore provides the optimal atmosphere to provide clinical and statistical support to the field of sports psychology. Despite the various, numerous pieces of literature that praise and show support for sports psychology, there hasn’t been clinical research to support it. Additionally, multiple ...


Time, Number, Space, And The Domestic Dog, Krista M. Macpherson 2018 The University of Western Ontario

Time, Number, Space, And The Domestic Dog, Krista M. Macpherson

Electronic Thesis and Dissertation Repository

Over the past 20 years, the field of animal cognition has seen a dramatic increase in the attention given to the study of cognition in the domestic dog. Since their origin at least 10, 000 years ago, dogs have been artificially selected by humans to protect our homes, guard our livestock, pull our sleds, and a multitude of other functions. Given their close relationship with humans, much of the current research in the area of dog cognition to date has focused on aspects of social cognition. Considerably less attention has been paid to domains that have traditionally been areas of ...


Identifying The Social Contexts Present For Mouthing Behaviors In Bottlenose Dolphins (Tursiops Truncatus), Erin E. Frick 2018 University of Southern Mississippi

Identifying The Social Contexts Present For Mouthing Behaviors In Bottlenose Dolphins (Tursiops Truncatus), Erin E. Frick

Dissertations

Much of the research on dolphin communication has focused on the acoustic signals produced in a variety of social contexts. Although acoustic signals are undoubtedly an important aspect of dolphin communication systems, dolphin communication is multifaceted and multimodal (e.g., postural, visual and tactile signals, acoustic cues). The present study examined behaviors that involve the mouth (i.e., mouthing behaviors) in a group of captive dolphins using 2,696 minutes of underwater acoustic and video recordings collected from 2010 – 2014. Target behaviors are described as primarily visual (e.g., open-mouth display), both visual and acoustic (e.g., jaw claps), and ...
