How Does The Brain Represent Digits? Investigating The Neural Correlates Of Symbolic Number Representation Using Fmri-Adaptation, Celia Goffin Oct 2019

How Does The Brain Represent Digits? Investigating The Neural Correlates Of Symbolic Number Representation Using Fmri-Adaptation, Celia Goffin

Electronic Thesis and Dissertation Repository

How does the brain represent numerical symbols (e.g., Arabic digits)? Activity in left parietal regions correlates with symbolic number processing. Research with functional resonance imaging adaptation (fMRI-A) indicates that the intraparietal sulcus (IPS) exhibits a rebound (increase in activation) effect when a repeatedly presented number is followed by a new number. Importantly, this rebound effect is modulated by numerical ratio as well as the difference between presented numbers (distance). This ratio-dependent rebound effect could reflect a link between symbolic numerical representation and an approximate number system (ANS). In this doctoral dissertation, fMRI-A is used to investigate mechanisms underlying symbolic number …

Interpersonal And Pet Attachment, Empathy Toward Animals, And Anthropomorphism: An Investigation Of Pet Owners In Romania, Alina Simona Rusu, Carmen Costea-Barlutiu, Dennis C. Turner Sep 2019

Interpersonal And Pet Attachment, Empathy Toward Animals, And Anthropomorphism: An Investigation Of Pet Owners In Romania, Alina Simona Rusu, Carmen Costea-Barlutiu, Dennis C. Turner

People and Animals: The International Journal of Research and Practice

The current study investigates the associations between interpersonal and pet attachment (anxiety and avoidance dimensions), empathy toward animals, and anthropomorphism in the Romanian cultural context, where problems regarding the effectiveness of pet management programs are still being reported. A sample of 244 adult respondents, with a mean age of 32.9 years, mostly females (89.8%) and pet owners, completed standard instruments of interpersonal and pet attachment, empathy toward animals and anthropomorphism. In agreement with other studies in the field of human-animal interactions, our data indicate that female pet owners scored higher than male owners in empathy toward animals and the level …


Fish Sentience Denial: Muddying The Waters, Lynne U. Sneddon, Javier Lopez-Luna, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Amanda D. Currie, Donald M. Broom, Culum Brown Sep 2019

Fish Sentience Denial: Muddying The Waters, Lynne U. Sneddon, Javier Lopez-Luna, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Amanda D. Currie, Donald M. Broom, Culum Brown

Lynne Sneddon, PhD

Recent empirical studies have reported evidence that many aquatic species, including fish, cephalopods and crustaceans, have the capacity for nociception and pain, and that their welfare should be taken into consideration. Some sceptics, rejecting the precautionary principle, have denied that any study demonstrates pain or other aspects of sentience in fish. This target article discusses some of the scientific shortcomings of these critiques through a detailed analysis of a study exploring nociception and analgesia in larval zebrafish.


Ample Evidence For Fish Sentience And Pain, Lynne U. Sneddon, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Donald M. Broom, Culum Brown Sep 2019

Ample Evidence For Fish Sentience And Pain, Lynne U. Sneddon, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Donald M. Broom, Culum Brown

Lynne Sneddon, PhD

The majority of commentaries are supportive of our position on the scepticism that muddies the waters surrounding fish pain and sentience. There is substantial empirical evidence for pain in fish. Animals’ experience of pain cannot be compared to artificial intelligence (AI) because AI can only mimic responses to nociceptive input on the basis of human observations and programming. Accepting that fish are sentient would not be detrimental to the industries reliant on fish. A more proactive discussion between scientists and stakeholders is needed to improve fish welfare for the benefit of all.


Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach Sep 2019

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach

Lynne Sneddon, PhD

Key (2016) affirms that we do not know how the fish brain processes pain but denies — because fish lack a human-like cortex — that fish can feel pain. He affirms that birds, like fish, have a singly-laminated cortex and that the structure of the bird brain is quite different from that of the human brain, yet he does not deny that birds can feel pain. In this commentary we describe how Key cites studies that substantiate mammalian pain but discounts the same kind of data as evidence of fish pain. We suggest that Key's interpretations are illogical, do not …


The Impact Of Statistical Learning On Language And Social Competency In Asd And Adhd: Divergent Findings, Kaitlyn M.A Parks Sep 2019

The Impact Of Statistical Learning On Language And Social Competency In Asd And Adhd: Divergent Findings, Kaitlyn M.A Parks

Electronic Thesis and Dissertation Repository

Statistical learning is a process that allows individuals to extract regularities from the environment and plays an important role in language acquisition, speech segmentation, and aspects of social behaviour. Little is known about the contribution of statistical learning impairments on Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) related traits. The current study examined whether impairments in auditory and visual statistical learning are related to ASD and ADHD traits, language, and social competency. Decreased auditory, but not visual statistical learning abilities was related to increased autism traits and visual statistical learning and social competency abilities were mediated by language comprehension. …


Raising Consciousness About Chicken Consciousness, Bernard Rollin Sep 2019

Raising Consciousness About Chicken Consciousness, Bernard Rollin

Bernard Rollin, PhD

The topics explored by Marino are definitive, and should work well to lay to rest forever the widespread belief that chickens have no personality, are unintelligent, or in any other way lack a mental life.


Far More To Sheep Than Meets The Casual Eye, Bernard Rollin Sep 2019

Far More To Sheep Than Meets The Casual Eye, Bernard Rollin

Bernard Rollin, PhD

Marino & Merskin’s survey of the cognitive and social capacities of sheep is an eye-opener about the individuality and emotionality of this most maligned of all farm animals. My own eyes had already been opened by an adopted orphaned lamb, so much more like a dog as a companion animal than the mindless robot I had been conditioned to expect. I am morally certain that Marino & Merskin’s survey will have a similar effect on readers open to changing their minds.


Raising The Moral Consciousness Of Science, Bernard Rollin Sep 2019

Raising The Moral Consciousness Of Science, Bernard Rollin

Bernard Rollin, PhD

Precaution on behalf of sentient animals should not be tempered by the questionable principle of the amorality of science.


Unity Of Consciousness In Animals, Bernard E. Rollin Sep 2019

Unity Of Consciousness In Animals, Bernard E. Rollin

Bernard Rollin, PhD

Both Descartes the rationalist and Hume the empiricist, polar opposites philosophically, denied the unity and continuity of animal mind. Kant pointed out that the presence of retrievable memories entails unity of consciousness. Rowlands now argues that animals too have unity of consciousness.


Human Superiority?, Bernard Rollin Sep 2019

Human Superiority?, Bernard Rollin

Bernard Rollin, PhD

Like Charles Darwin and George Romanes, I am quite willing to use anecdotal information as a source of knowledge about animal behavior. There are many more people observing nonhuman animals than there are people conducting controlled experiments, and we can thereby learn that behaviors we think are unique to humans are shared by other animals. From a strictly biological point of view, it makes no sense to speak of “human superiority.” One species of animal can be superior to another only in terms of survival and niche occupation. As moral concern for animals increases across the world, claims of human …

Thinking About Thinking Chickens, Lori Marino Sep 2019

Thinking About Thinking Chickens, Lori Marino

Lori Marino, PhD

This response focuses on three major conceptual threads that run through the peer commentary on my target article: (1) how the use of chickens influences our views of them, (2) whether education is effective, and (3) what components of chicken psychology are most relevant to understanding who chickens are.



“I Am Not An Animal”, Lori Marino Sep 2019

“I Am Not An Animal”, Lori Marino

Lori Marino, PhD

The answer to Chapman & Huffman’s question — “Why do we want to think humans are different?” — lies in the work of Ernest Becker and the social psychology literature known as Terror Management Theory, according to which our deep anxiety about animality and death can drive our need to feel superior to the other animals.


Deepening Our Understanding Of Sheep, Lori Marino, Debra Merskin Sep 2019

Deepening Our Understanding Of Sheep, Lori Marino, Debra Merskin

Lori Marino, PhD

Our Response is centered on five major themes: (1) our presentation of human mythologies about sheep; (2) the relevance of cognitive complexity (“intelligence”) as a dimension underlying the way people perceive and treat sheep; (3) whether our review is too anthropocentric or anthropomorphic; (4) animal welfare versus animal rights (abolitionism); and (5) whether knowledge and education are enough to change human attitudes and behavior.


Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino Sep 2019

Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino

Lori Marino, PhD

Mather argues convincingly for the existence of minds in octopuses based largely on laboratory experiments. Many of these experiments are highly invasive and involve mutilation and death. Moreover, octopuses are now being hailed as a “new model” for biological research and are being enthusiastically bred in captivity, both for research and for food. We argue that the compelling evidence for mind in octopuses must be accompanied by intense scrutiny of the ethics that shape how we treat them and that the intrinsic value of their individual lives must be recognized.


The Inconvenient Truth About Thinking Chickens, Lori Marino Sep 2019

The Inconvenient Truth About Thinking Chickens, Lori Marino

Lori Marino, PhD

Original Abstract: 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. Some birds are now known to be on a par with many mammals in their intelligence, emotional sophistication, and social interaction. Yet views of chickens have largely remained unrevised in light of this new evidence. In this paper, I examine the data on cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities with other birds and other vertebrates, particularly …


Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin Sep 2019

Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin

Lori Marino, PhD

Domestic sheep (Ovis aries) are among the earliest animals domesticated for human use. They are consumed worldwide as mutton, hogget, and lamb, kept as wool and milk producers, and used extensively in scientific research. The popular stereotype is that sheep are docile, passive, unintelligent, and timid, but a review of the research on their behavior, affect, cognition, and personality reveals that they are complex, individualistic, and social.


Debunking Human Prejudice And Blindness, Peter J. Li Sep 2019

Debunking Human Prejudice And Blindness, Peter J. Li

Peter J. Li, PhD

Human prejudice and blindness to animal suffering are shocking. Despite their differences in culture, politics, and religious beliefs, humans have one thing in common. They see nonhuman animals as inferior and have since time immemorial assumed a dominant position in an asymmetrical human-animal relationship. When it comes to human-animal relations, there is no “clash of civilizations.” Human prejudice and blindness are predicated on “common sense assumptions” about the natural world and nonhuman animals in particular. Marino & Merskin’s review is part of the growing effort to debunk the assumptions that have shaped human actions so as to end the injustice …


The Precautionary Principle: A Cautionary Note, Robert C. Jones Sep 2019

The Precautionary Principle: A Cautionary Note, Robert C. Jones

Robert C. Jones, PhD

The precautionary principle regarding animal sentience is often used in decision-making about human actions that may cause harm to nonhuman animals. Birch (2017) develops an account of the precautionary principle requiring two pragmatic rules for its implementation. I support Birch's proposal but offer a cautionary note about relying on precautionary principles if one's ultimate goal is to emancipate animals from human domination.


Fish Sentience Denial: Muddy Moral Water, Robert C. Jones Sep 2019

Fish Sentience Denial: Muddy Moral Water, Robert C. Jones

Robert C. Jones, PhD

Sneddon et al. (2018) authoritatively summarize the compelling and overwhelming evidence for fish sentience, while methodically dismantling one rather emblematic research paper (Diggles et al. 2017) intended to discount solid evidence of fish sentience (Lopez-Luna et al. 2017a, 2017b, 2017c, & 2017d). I explore the larger practical moral contexts within which these debates take place and argue that denials of animal sentience are really moral canards.


The Person And The Self As Social Accomplishment, Leslie Irvine Sep 2019

The Person And The Self As Social Accomplishment, Leslie Irvine

Leslie Irvine, PhD

Rowlands (2016) presents a compelling argument for extending personhood to nonhuman animals. Sociological conceptions of the person also do not require that animals meet the elusive standard of self-awareness. Sociological ideas on selfhood support the claims about pre-reflective awareness and extend the requisite experiences to animals.


Animal Pain And The Social Role Of Science, Leslie Irvine Sep 2019

Animal Pain And The Social Role Of Science, Leslie Irvine

Leslie Irvine, PhD

Assuming that all animals are sentient would mean ending their use in most scientific research. This does not necessarily imply an unscientific or anti-scientific stance. Examining the social role of science reveals its considerable investment in preserving the status quo, including the continued use of animal subjects. From this perspective, the use of animal subjects is a custom that science could move beyond, rather than a methodological requirement that it must defend.


The Feedback Effect: Does Exposure To Interviewer Feedback Affect An Observer's Perception Of Veracity And Guilt?, Kayla A. Harrod Sep 2019

The Feedback Effect: Does Exposure To Interviewer Feedback Affect An Observer's Perception Of Veracity And Guilt?, Kayla A. Harrod

Student Theses

Historically, assessing deception has been rooted in the belief that a guilty suspect displays signs of anxiety. Based on a suspect’s physical demeanor and other behavioral cues presented during an interrogative session, law enforcement personnel (LEP) will utilize a set of techniques to elicit information about a crime. One such technique is the administration of feedback, which is the verbal assessment of a suspect’s guilt. The issue that stems from administering feedback lies not only in how it is given but also how it is received and interpreted by others. In a two-part study, the possibility of a “Feedback Effect” …


A Vision-Based Model Of Crowd Navigation, Gregory C. Dachner Sep 2019

A Vision-Based Model Of Crowd Navigation, Gregory C. Dachner

Link Foundation Modeling, Simulation and Training Fellowship Reports

Humans navigate crowds daily. This can range from quick interactions between pedestrians on the sidewalk to jostling through a busy train station. Research in fields diverse as computer graphics, physics, evacuation planning, and mathematical biology have simulated emergent collective behavior in flocks, schools, and crowds (Couzin et al., 2002; Helbing & Molnár, 1995; Reynolds, 1987; Vicsek & Zafeiris, 2012). However, few of these models are built from experimental evidence about the visual information that governs human pedestrian behaviors in naturalistic environments. This project, funded by the Link Foundation, empirically studied and computationally modeled how individuals in a crowd use visual …


Women's Perceptions Of Sexual Assault Perpetrators And Fear Of Rape, Aaron George Cisneros Sep 2019

Women's Perceptions Of Sexual Assault Perpetrators And Fear Of Rape, Aaron George Cisneros

Electronic Theses, Projects, and Dissertations

The overarching goal of the present thesis was to study women’s perceptions of sexual assault perpetrators and how those perceptions relate to fear of sexual assault. Previous researchers have developed a substantial literature on predictors and correlates of sexual assault perpetration. What is not known is how accurate women’s perceptions are of these predictors. Rationale from both evolutionary mismatch theory and social psychological stereotype theory suggests that women’s perceptions may be inaccurate. In the present thesis, I tested a set of hypotheses designed to examine individual differences in women’s perceptions of sexual assault perpetrators and how these perceptions relate to …


Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray Sep 2019

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …


Neural Correlates Of Automatic Emotional Processing And Emotion Regulation In Empathy And Psychopathy-Related Coldheartedness, Danielle Difilipo Sep 2019

Neural Correlates Of Automatic Emotional Processing And Emotion Regulation In Empathy And Psychopathy-Related Coldheartedness, Danielle Difilipo

Dissertations, Theses, and Capstone Projects

Psychopathy is a personality disorder that is defined, in part, by a lack of empathy. Psychopathy-related empathic deficits have been associated with atypical behavioral and neural responses to emotional facial expressions. Although the mirror neuron system (MNS) has been implicated in empathy, very few studies have examined the role of MNS functioning as it pertains to empathy impairments in psychopathy. Moreover, there is very little empirical research regarding emotion regulation in psychopathy, and specifically whether emotional responses can be intentionally upregulated. The present study sought to clarify whether the MNS is functionally intact in adults with subclinical psychopathic traits, particularly …


Internal And External Attention In Autism Spectrum Disorder, Tehila Eilam-Stock Sep 2019

Internal And External Attention In Autism Spectrum Disorder, Tehila Eilam-Stock

Dissertations, Theses, and Capstone Projects

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental condition affecting individuals throughout the lifespan. Sensory hypersensitivity and superior perceptual acuity are well documented in individuals with ASD, and may indicate heightened orientation of attention to external stimuli, as attention can augment sensory perception. Recent evidence from mind-wandering research suggests that the ability to disengage attention from the external environment and direct it internally to self-generated mentation is crucial for adaptive cognition and behavior, as it allows for incorporation of past knowledge and experience in the interpretation of novel situations. We hypothesized that ASD is related to an imbalance between externally …
