Fish Pain: Would It Change Current Best Practice In The Real World?, B. K. Diggles

Animal Sentience

Much of the “fish pain debate” relates to how high the bar for pain should be set. The close phylogenetic affinities of teleosts with cartilaginous fishes which appear to lack nociceptors suggests caution should be applied by those who seek to lower the bar, especially given the equivocal and conflicting nature of the experimental data currently available for teleosts. Nevertheless, even if we assume fish “feel pain,” it is difficult to see how current best practice in aquaculture would change. This is because of the need to avoid stress at all stages of the rearing process to optimize health, growth …

Leaving The Door Open For Fish Pain: Evolutionary Convergence And The Utility Of ‘Just-So Stories’, David B. Edelman

Animal Sentience

Key argues that fish do not experience pain because they lack the necessary (but not necessarily sufficient) brain structures and associated functional circuitry to engender such conscious percepts. I propose that fish pain may be dependent on neuroanatomical regions and pathways that are structurally and/or functionally analogous — but not strictly homologous — to well-characterized mammalian substrates of pain. An example is the convergent appearance of the complex, single-compartment eye across invertebrate and vertebrate phylogeny. Structural-functional convergence is ubiquitous in evolution. Comparative inferences and correlative lines of evidence play an important role in building evolutionary arguments. The dismissal of the …

Pain-Capable Neural Substrates May Be Widely Available In The Animal Kingdom, Edgar T. Walters

Animal Sentience

Neural and behavioral evidence from diverse species indicates that some forms of pain may be generated by coordinated activity in networks far smaller than the cortical pain matrix in mammals. Studies on responses to injury in squid suggest that simplification of the circuitry necessary for conscious pain might be achieved by restricting awareness to very limited information about a noxious event, possibly only to the fact that injury has occurred, ignoring information that is much less important for survival, such as the location of the injury. Some of the neural properties proposed to be critical for conscious pain in mammals …

How Not To Move The Line Drawn On Pain, Bjorn H. Merker

Animal Sentience

In this second commentary I outline the inadequacy of Key's responses to the many peer critiques of his thesis that have so far appeared in Animal Sentience. I illustrate with examples drawn from his response to my first commentary.

Nonverbal Indicators Of Pain, Simon Van Rysewyk

Animal Sentience

In discussing fish pain, Key (2016) privileges pain in humans — “the only species able to directly report on its feelings.” Human experience of pain is not necessarily best reflected by verbal self-report, however. Neural responses to noxious stimuli are influenced by individual differences and by context. Nonverbal pain displays such as facial expressions reflect part of the neural response to noxious stimuli. Most mammals have a specific facial grimace reflecting pain. If fish have a somatic expression of pain, the development of a reliable and accurate somatic pain scale specific to fish could make a contribution to the debate …

Fish Pain: An Inconvenient Truth, Culum Brown

Animal Sentience

Whether fish feel pain is a hot political topic. The consequences of our denial are huge given the billions of fish that are slaughtered annually for human consumption. The economic costs of changing our commercial fishery harvest practices are also likely to be great. Key outlines a structure-function analogy of pain in humans, tries to force that template on the rest of the vertebrate kingdom, and fails. His target article has so far elicited 34 commentaries from scientific experts from a broad range of disciplines; only three of these support his position. The broad consensus from the scientific community is …

An Examination Of The Factors That Dictate The Relative Weighting Of Feedback And Feedforward Input For Speech Motor Control, Nichole E. Scheerer

Theses and Dissertations (Comprehensive)

Speech is arguably the most important form of human communication. Fluent speech production relies on auditory feedback for the planning, execution, and monitoring of speech movements. Auditory feedback is particularly important during the acquisition of speech, however, it has been suggested that over time speakers rely less on auditory feedback as they develop robust sensorimotor representations that allow speech motor commands to be executed in a feedforward manner. The studies reported in this thesis recorded speaker’s vocal and neural responses to altered auditory feedback in order to explore the factors that dictate the relative importance of auditory feedback for speech …

Multisensory Cue Congruency In Lane Change Test, Yuanjing Sun

Dissertations, Master's Theses and Master's Reports

Nowadays, a driver interacts with multiple systems while driving. Multimodal in-vehicle technologies (e.g., Personal Navigation Devices) intend to facilitate multitasking while driving. Multimodality enables to reduce cognitive effort in information processing, but not always. The present study aims to investigate how/when auditory cues could improve driver responses to a visual target. We manipulated three dimensions (spatial, semantic, and temporal) of verbal and nonverbal cues to interact with visual spatial instructions. Multimodal displays were compared with unimodal (visual-only) displays to see whether they would facilitate or degrade a vehicle control task. Twenty-six drivers participated in the Auditory-Spatial Stroop experiment using a …

East-West Cultural Differences In Visual Attention Tasks: Identifying Multiple Mechanisms And Developing A Predictive Model, Yin Yin Tan

Dissertations, Master's Theses and Master's Reports

Past research has identified East-West differences in visual attention associated with holistic versus analytic perception and reasoning strategies (Nisbett et al., 2001; Boduroglu et al., 2009). These cross-cultural differences might stem from several different mechanisms, which may include: interference suppression, response inhibition, attention to detail vs. object configuration, stimulus centrality vs. eccentricity, number of visual distractors (e.g., display set size or clutter), and others.

Although research has shown East-West differences, the results sometimes appear inconsistent with each other, or they lack clear predictions from underlying theories. For example, evidence of a preference for cluttered displays (Wang et al., 2012), evidence …

The Influence Of Freedom And Choice In Action Selection And The Valence Of Action-Outcomes On The Sense Of Agency, Zeynep Barlas Wilfrid Laurier University

Theses and Dissertations (Comprehensive)

Sense of agency (SoA) refers to the subjective experience that one is the author of their actions and the ensuing outcomes of these actions. Previous research have suggested that both sensorimotor processes and high level inferences can contribute to the SoA. In five experiments, the present thesis examined the effects of action selection processes and the valence of action-outcomes on the SoA. The majority of these experiments measured the SoA by obtaining both subjective feeling of control (FoC) judgments over the action-outcomes, and assessing the size of intentional binding. Intentional binding refers to the perceived temporal attraction between actions and …

How Can We Build A Moral Robot?, Kristen E. Clark

Capstones

Artificial intelligence is already starting to drive our cars and make choices that affect the world economy. One day soon, we’ll have robots that can take care of our sick and elderly, and even rescue us in rescue us in emergencies. But as robots start to make decisions that matter—it’s raising questions that go far beyond engineering. We’re stating to think about ethics.

Bertram Malle and Matthias Scheutz are part of a team funded by the department of defense. It's their job to answer a question that seems straight out of a sci-fi novel: How can we build a moral …

Detecting Changes In Auditory Events, Rachael B. Peck

Masters Theses, 2010-2019

Change deafness is defined as the failure to detect the source of an above-threshold change in an auditory scene. A new paradigm recently demonstrated the phenomenon under analogous conditions to its visual counterpart, change blindness (Hall, Peck, Gaston, & Dickerson, 2015). This investigation examined the use of the paradigm through two experiments which involved the same four simultaneously presented events. Experiment 1 distributed events across a virtual 120º on the azimuth while the target event oscillated across a 60º space throughout each trial. Listeners were instructed to identify the target as soon as possible. Target rate of change was manipulated …

The Impact Of Globalization On Access For Individuals With Disabilities, Katherine Williamson

Honors Theses

This comparative ethnomethodology study is focused on the global context elements that help explain public policies and its consequences on types of access available to individuals with disabilities in the United States Midwest and West Africa. The goal of this study is to identify the role of individuals with disabilities in a global society by answering two research questions. First, what are the public policies in place for physical, social, and educational access in the United States Midwest and West Africa? Second, how is physical, social, and educational access being provided in the United States Midwest and West Africa? The …

The Effects Of Mindfulness On Verbal Distress Disclosure, Sara Fleming

USC Aiken Psychology Theses

The purpose of this study was to investigate the effect of a mindfulness induction on participants’ verbal distress disclosure (as measured by the Linguistic Inquiry and Word Count and State Disclosure Questionnaire). Participants were 86 undergraduate students enrolled in an Introduction to Psychology course and were randomly assigned to one of two conditions: a mindfulness condition or a control condition. Participants in the mindfulness condition engaged in a 15-minute mindfulness induction prior to disclosing about a stressful experience, while participants in the control condition listened to a neutrally valenced audio excerpt from a podcast about emotions before speaking about a …

Aesthetics And Performance Evaluation Of Post-Industrial Public Parks, Adel C. Vaughn

Landscape Architecture Undergraduate Honors Theses

Post-Industrial sites are often un-utilized and deserted places that are an aesthetic, social, ecological, and physical hindrance to the realm of the cities in which they lie, however they possess enormous potential. With respectful and transformative design, these new public parks gain a variety of benefits that extend well beyond the typical benefits exhibited by public parks due to their rich history, fascinating existing structures, high levels of visual and sensorial stimulation, one-of-a-kind traits, and opportunity for impactful change. By evaluating these post-industrial public parks, knowledge can be gained about what specific elements in the landscape contribute to their overall …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

Nurses’ Perceptions Of Self As Role Models Of Health, Shelia Hurley

Electronic Theses and Dissertations

Given the sad state of obesity and lifestyle-related illnesses in the US, nurses, as the largest and most trusted health profession, must take the cause of health promotion seriously and personally. This study seeks to close the gap in knowledge of nurses’ perception of self as a role model of health and personal healthy lifestyle behaviors. This study focuses on four specific behaviors that lead to a healthy lifestyle: limit alcohol, avoid tobacco, improve nutrition, and engage in physical activity. The purpose of this study is to determine the relationship between nurses’ health practices and their perceptions of self as …

Physiological Response To Dissonance In Musicians And Nonmusicians, Angela Beth Biehl

Masters Theses

Knowing the human response to musical dissonance could have important therapeutic implications in the music therapy setting. The listener’s musical experience could significantly impact their response and subsequently its effect in a therapeutic setting. Thus, this study aimed to examine both the psychophysiological and subjective responses to dissonance and the difference in these responses between those with high experience and those with low experience. Participating groups, categorized as high experience (HE) and low experience (LE) in terms of musical knowledge, listened to consonant and dissonant musical excerpts, and rated each excerpt on its pleasantness; their physiologic responses were measured to …

Increases In Perspective Embedding Increase Reading Time Even With Typical Text Presentation: Implications For The Reading Of Literature, D. H. Whalen, Lisa Zunshine, Michael Holquist

Publications and Research

Reading fiction is a major component of intellectual life, yet it has proven difficult to study experimentally. One aspect of literature that has recently come to light is perspective embedding (“she thought I left” embedding her perspective on “I left”), which seems to be a defining feature of fiction. Previous work (Whalen et al., 2012) has shown that increasing levels of embedment affects the time that it takes readers to read and understand short vignettes in a moving window paradigm. With increasing levels of embedment from 1 to 5, reading times in a moving window paradigm rose almost linearly. However, …

Perceptions Of Tornadoes, Tornado Warnings, Safety Actions, And Risk: Effects On Warning Response Among Undergraduates In Nebraska, Sabrina T. Jauernic

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Few studies show how university students perceive and respond to tornado warnings, or how they gain tornado-related knowledge. Lacking in the literature are investigations of how perceptions of tornado risk may influence actions. Using two separate surveys and two large samples of undergraduates enrolled in the University of Nebraska, the author determined significant relationships between student demographics, perceptions, and response actions. Incorrect perceptions were found, such as overpasses and southwest corners of buildings being safe, and cities being invulnerable to tornadoes. International students, especially, assumed cities were safe from tornadoes. Students had a tendency to confirm their risk instead of …

Perceptions, Stereotypes And Cognitive Resources Of Female Businesspersons: A Social Identity Approach, Amy J. Y. Lim

Dissertations and Theses Collection (Open Access)

According to the Stereotype Content Model (SCM), female businesspersons are often stereotyped and labeled either as a Career Women, competent but cold, or as a Traditional Women, warm but incompetent. This suggests that female businesspersons are generally perceived to be either competent or warm individuals, but not both. However, this may not reflect female businesspersons’ own perceptions of their competence and warmth in the workplace. Contrary to the stereotypes, evidence has demonstrated that some female businesspersons display behaviors that signal both competence and warmth. Employing a social identity approach, I propose that gender-professional identity integration (G-PII), an individual difference that …

Sweet Love: The Effects Of Sweet Taste Experience On Romantic Perceptions, Ren Dongning, Kenneth Tan, Ximena B. Arriaga, Kai Qin Chan

Research Collection School of Social Sciences

Terms of endearment such as sweetie, honey, and sugar are commonly used in the context of describing romantic partners. This article explores how a relatively subtle manipulation, namely taste sensations, might influence romantic perceptions of a nonestablished relationship. Consistent with predictions, results from Studies 1 and 2 (n = 280) showed that participants evaluated a hypothetical relationship, but not an existing relationship, more favorably when exposed to sweet taste compared to non-sweet taste control. Study 3 (n = 142) further showed that participants indicated greater interest in initiating a relationship with a potential partner when exposed to sweet taste, as …

The Effects Of Aging On Associative Learning And Memory Retrieval In Causal Judgment, Jessica Parks Arnold

Masters Theses & Specialist Projects

Research has shown that detecting and judging causal relationships requires associative learning and memory. Retrospective revaluation of causal cues requires associative memory (Aitken, Larkin, & Dickinson, 2001) to bind multiple cues together and use these associations to retrieve unseen cues for revaluation of their associative value. The difficulty that older adults experience with respect to retrospective revaluation could occur because of their deficit in associative binding and retrieval (Mutter, Atchley, & Plumlee, 2012). Like retrospective revaluation, blocking requires cue – outcome associative learning, but unlike retrospective revaluation, blocking does not require binding two cues together nor does it require using …

Age And Context Dependency In Causal Learning, Katherine Danielle Lowry

Masters Theses & Specialist Projects

The ability to make associations between causal cues and outcomes is an important adaptive trait that allows us to properly prepare for an upcoming event. Encoding context is a type of associative processing; thus, context is also an important aspect of acquiring causal relationships. Context gives us additional information about how two events are related and allows us to be flexible in how we respond to causal cues. Research indicates that older adults exhibit an associative deficit as well as a deficit in contextual processing; therefore, it seems likely that these deficits are responsible for the deficit in older adults’ …

Investigating The Ichthus (Fish) Christianity Symbol On Perceived Source Credibility Of Service Providers Under Different Service Evaluation Contexts, Jeri L. Jones, Mahmood T. Shandiz

Atlantic Marketing Association Proceedings

Combining religious practices with commercial pursuits for profit is neither a novel nor an insignificant trend (Belk, Wallendorf, and Sherry 1989; McDannell 1995). Today, marketplace use of Christian symbols in secular advertising is becoming more common, especially in certain geographic locations within the United States. Christian religion-based messages and symbols regularly appear in a wide range of advertisements. The Christian elements in these ads often include Bible verses, crosses, doves, and often, the Christian fish symbol (Ichthus). Similar Christian messages are often observed in outdoor advertising, retail store signage, product packaging, and even the daily newspaper. These examples illustrate that …

Music Listening As Therapy, David M. Rosenblatt

Loma Linda University Electronic Theses, Dissertations & Projects

Music is a universal phenomenon and is a real, physical thing. It is processed in neural circuits that overlap with language circuits, and it exerts cognitive, emotional, and physiological effects on humans. Many of those effects are therapeutic, such as reduced symptoms of physical and mental ailments. Music is the result of the elements rhythm, melody, harmony, timbre, dynamics, and form. Rhythm is the focus of pop music, and melody is the focus of classical music. The mind perceives and organizes music in learned, consistent ways in order to generate predictions and extract meaning. There are perceptual laws and information …

Locke, Judgment, And Figure: A Consistent Answer To The Molyneux Problem, Jamale Nagi

Anthós

John Locke has been famously credited with resurrecting the distinction between common and proper sensibles, better known in the Essay as primary and secondary qualities. Although some argue that Locke’s adherence to the doctrine of the common sensibles is in conflict with his empiricist sensibilities, I will show this is not likely to be the case. In order to achieve this I will argue that Locke held there to be cross-modal connections in the mind for the representational content of ideas of primary quality, through the relation of resemblance, but that these representations need to be empirically verified to …

Spatial Estimation: A Non-Bayesian Alternative, Hilary Barth, Ellen Lesser, Jessica Taggart, Emily Slusser

Faculty Publications

A large collection of estimation phenomena (e.g. biases arising when adults or children estimate remembered locations of objects in bounded spaces; Huttenlocher, Newcombe & Sandberg, 1994) are commonly explained in terms of complex Bayesian models. We provide evidence that some of these phenomena may be modeled instead by a simpler non-Bayesian alternative. Undergraduates and 9- to 10-year-olds completed a speeded linear position estimation task. Bias in both groups’ estimates could be explained in terms of a simple psychophysical model of proportion estimation. Moreover, some individual data were not compatible with the requirements of the more complex Bayesian model.

Toward A Two-Stage Model Of Free Categorization, Gregory J. Smith

Electronic Theses, Projects, and Dissertations

This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

Culture And Cognition: The Role Culture Plays In Cognitive Development In Rural Tanzania, Eileen Seissen

Capstone Collection

This capstone paper examines the perceived difference of cognition in a Tanzanian classroom. It also examines the effects culture has on cognition. It aims to answer the questions: What role does Tanzanian culture play in shaping the cognitive skills of its children? And, from an American trainers perspective, within an experiential learning environment, what cognitive differences are perceived in abstract thinking, creativity, critical thinking, and problem-solving? Nine American trainers, one Tanzanian trainer, and one Tanzanian student participated in my study. Each participant filled out a questionnaire geared toward understanding their training methods and perceptions of participant's skills and abilities. After …
