Animal Suffering And Human Bias, Stijn Bruers

Animal Sentience

Ng proposes concrete ways to decrease animal suffering on the basis of commonsense economic logic and research in welfare biology. But to reduce animal suffering effectively in livestock farming, animal experimentation or the natural environment we have to become more aware of our pervasive and spontaneous but unreliable intuitive moral judgments. These can generate biases that prevent us from decreasing animal suffering effectively.

An Animal Victim's Best Chance: Veterinary Legal Duty To Report Cruelty In The U.S., Lora Dunn

Animal Sentience

Legislation throughout the U.S. recognizes animal sentience and the importance of veterinary reporting to combat the ongoing suffering of these animal victims: All 50 states have felony penalties available for animal cruelty crimes, and veterinary reporting is permitted or required in the majority of states. The remaining minority of U.S. states should take action to require veterinarians to report animal cruelty and render veterinarians immune for good faith reporting.

Veterinary Medical Associations Need To Educate Veterinarians For Mandatory Reporting Of Suspected Animal Abuse, Melinda V. Merck

Animal Sentience

When animals are suffering, we have a duty to take action. With appropriate incentive and educational support mandatory veterinary reporting can be a great legal avenue to help ensure their safety and welfare.

Fish Pain's Burden Of Proof, Carl Safina

Animal Sentience

A hypothesis like Key’s, that fish cannot feel pain, should really be stated as a null hypothesis — an assumption that there is no difference in the things being compared. Then evidence — including anecdotal evidence — for and against rejecting the null hypothesis can be examined and weighed. Key (2016a) has proven only that fish lack mammalian brains.

Burden Of Proof Lies With Proposer Of Celestial Teapot Hypothesis, Brian Key

Animal Sentience

Bertrand Russell famously imagined the existence of a celestial teapot to highlight that the burden of proof of a hypothesis lay with its proposer and it was not the responsibility of others to refute it. Those who propose that fish feel pain must bear the burden of proof for their hypothesis. There are several common arguments adopted by those defending the position that fish feel pain. For instance, proponents envisage that pain is so important for human survival that they can’t imagine fish could exist without it. Out of this argument from incredulity emerges the idea that pain must have …

Animal Suffering In China, Peter J. Li

Animal Sentience

Chinese policy has been aimed at maximizing GDP; it is time to focus also on minimizing animal suffering.

Science And Sensibility, Bernard E. Rollin

Animal Sentience

The sentience and suffering of animals is obvious to common sense, even if science and industry claim to be agnostic. Economic incentives to reduce the suffering of animals are welcome, but it is not clear whether animals can turn to science for help.

When The Client Is Not The Abuser, But One Of The Abused, Tania Signal

Animal Sentience

The question of client confidentiality and reporting animal abuse is complicated when the client is not the abuser, and when the abuse (of both people and animals) may escalate precisely because it has been (or may be) reported.

Naïve Physics And Quantum Mechanics: The Cognitive Bias Of Everett’S Many-Worlds Interpretation, Andrew Lang

College of Science and Engineering Faculty Research and Scholarship

We discuss the role that intuitive theories of physics play in the interpretation of quantum mechanics. We compare and contrast naïve physics with quantum mechanics and argue that quantum mechanics is not just hard to understand but that it is difficult to believe, often appearing magical in nature. Quantum mechanics is often discussed in the context of "quantum weirdness" and quantum entanglement is known as "spooky action at a distance." This spookiness is more than just because quantum mechanics doesn't match everyday experience; it ruffles the feathers of our naïve physics cognitive module. In Everett's many-worlds interpretation of quantum mechanics, …

Commercial Aircraft Electronic Checklists: Benefits And Challenges (Literature Review), Paul L. Myers Iii

International Journal of Aviation, Aeronautics, and Aerospace

Procedural omissions and errors have been an inherent problem in aviation since 1935 when a B-17 crashed shortly after takeoff to the era of today’s advanced aircraft. Paper, then electronic, checklists were developed to address those omissions and errors. Electronic checklists attempt to further reduce paper checklist errors and results indicate some improvements have occurred. However, new error modes and unique challenges surfaced with electronic checklists that must be recognized and addressed.

Note: This is a non-peer refereed literature review paper.

A Mendelian Randomization Study Of Testosterone And Cognition In Men, Jie Zhao, Tai Hing Lam, Chaoqiang Jiang, Stacey S. Cherny, Bin Liu, Kar Keung Cheng, Weisen Zhang, Gabriel M. Leung, C Mary Schooling

Publications and Research

Testosterone replacement for older men is increasingly common, with some observations suggesting a protective effect on cognitive function. We examined the association of endogenous testosterone with cognitive function among older men in a Mendelian randomization study using a separate-sample instrumental variable (SSIV) analysis estimator to minimize confounding and reverse causality. A genetic score predicting testosterone was developed in 289 young Chinese men from Hong Kong, based on selected testosterone-related single nucleotide polymorphisms (rs10046, rs1008805 and rs1256031). The association of genetically predicted testosterone with delayed 10-word recall score and Mini-Mental State Examination (MMSE) score was assessed at baseline and follow-up using …

Reconstructing Representations Of Dynamic Visual Objects In Early Visual Cortex, Edmund Chong, Ariana M. Familiar, Won Mok Shim

Dartmouth Scholarship

As raw sensory data are partial, our visual system extensively fills in missing details, creating enriched percepts based on incomplete bottom-up information. Despite evidence for internally generated representations at early stages of cortical processing, it is not known whether these representations include missing information of dynamically transforming objects. Long-range apparent motion (AM) provides a unique test case because objects in AM can undergo changes both in position and in features. Using fMRI and encoding methods, we found that the “intermediate” orientation of an apparently rotating grating, never presented in the retinal input but interpolated during AM, is reconstructed in population-level, …

The Effect Of The Long Anchor Duration On Performance In The Temporal Bisection Procedure, Sho Araiba

Dissertations, Theses, and Capstone Projects

The present study investigated the determinants of the location of the bisection point (BP) in the temporal bisection procedure. Interest in the study of temporal perception emerged from the finding of the scalar property such as Weber’s law for time and the ratio rule in behavior under Pavlovian and instrumental conditioning. One method to investigate temporal perception in both non-human animals and humans is the temporal bisection procedure. The primary dependent variable of this procedure is the BP, which has been taken as the subjective midpoint between two durations. The ratio similarity rule (Gibbon, 1981) hypothesizes that the location of …

The Impact Of Affect On Neural Mechanisms Underlying Orientation Perception, Michelle L. Fowler

Dissertations, Theses, and Capstone Projects

The underlying mechanisms used to process 2D visual information to form a unified 3D percept of the world remain largely unknown. Previous work in our lab has shown that accurate 3D perception of textured surfaces depends on the presence of specific patterns of orientation flows in the retinal image. Recent research has shown that affective state may influence the visual perception of oriented patterns. Relative to neutral face stimuli, fearful face stimuli have been shown to increase sensitivity to orientation of low spatial frequency patterns and decrease sensitivity to orientation of high spatial frequency patterns. How affective state influences the …

Wandering In Contemporary Literature: A Narrative Theory Of Cognition, Hillel E. Broder

Dissertations, Theses, and Capstone Projects

This study offers a theory of wandering cognition as an animating feature of western literature, in general, and of contemporary literature, in particular. Unlike existing theories of peripatetic bodies and minds in fiction that focus primarily on political critiques, cultural practices, or pleasures of digression, this theory of wandering offers an aesthetic philosophy and ethical critique of representing cognition, memory, and narrative identity that finds affinities in the political, phenomenological, and ethical thought of Walter Benjamin, Emmanuel Levinas, and Giorgio Agamben.

Unlike existing cognitive theories of literature that apply cognitive theory to literary study (or vice versa), this study develops …

The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root

Publications and Research

There is accumulating evidence that sleep as well as awake offline processing is important for the transformation of new experiences into long-term memory (LTM). Yet much remains to be understood about how various cognitive factors influence the efficiency of awake offline processing. In the present study we investigated how changes in attention and context in the immediate period after exposure to new visual information influences LTM consolidation. After presentation of multiple naturalistic scenes within a working memory paradigm, recognition was assessed 30 min and 24 h later in three groups of subjects. One group of subjects engaged in a focused …

Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul

School of Psychology Publications

The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

La Responsabilidad Social, Un Componente Esencial De La Formación En Un Programa De Química Ambiental, Liliana Caycedo Lozano, Diana Marcela Trujillo Suárez, Sara Soledad Garcia

Teacher Education

The complexity of the current environmental situation in Colombia requires professionals integrally trained with the guidelines of transformation aimed at overcoming the effects of traditional methodological paradigms of teaching and learning. The professional should have a conceptual understanding of nature as a system of systems, which include human beings. The future of the planet needs not to focus only on "good practices", such required education is to consider the interconnection of all systems of the environment; as well as a plan that includes a vision that harmonizes the balance between all the natural elements through an interdisciplinary approach to transform …

Defining A Role For Affect In Decision-Making, Pareezad Cyrus Zarolia

Electronic Theses and Dissertations

Recent theories of decision-making have hinted that affect might be useful during some decision-making processes. I propose a model, the affective evaluation model, which defines the role of affect in decision-making as helpful when affect is decision-relevant and unhelpful when it is not. In three studies, I manipulate the decision-relevance of affect to test this central component of the affective evaluation model. Study 1 demonstrates that emphasizing decision-relevant affective signals facilitates optimal decision-making as compared to emphasizing purely cognitive evaluations. Study 2 tests the hypothesis that creating the expectation that affect is useful can facilitate decision-making. Finally, Study 3 tests …

Acquisition Of The Cardinal Principle Coincides With Improvement In Approximate Number System Acuity In Preschoolers, Anna Shusterman, Emily Slusser, Justin Halberda, Darko Odic

Faculty Publications

Human mathematical abilities comprise both learned, symbolic representations of number and unlearned, non-symbolic evolutionarily primitive cognitive systems for representing quantities. However, the mechanisms by which our symbolic (verbal) number system becomes integrated with the non-symbolic (non-verbal) representations of approximate magnitude (supported by the Approximate Number System, or ANS) are not well understood. To explore this connection, forty-six children participated in a 6-month longitudinal study assessing verbal number knowledge and non-verbal numerical acuity. Cross-sectional analyses revealed a strong relationship between verbal number knowledge and ANS acuity. Longitudinal analyses suggested that increases in ANS acuity were most strongly related to the acquisition …

Intertemporal Similarity: Discounting As A Last Resort, Jeffrey R. Stevens

Jeffrey Stevens Publications

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, Leland (2002) and Rubinstein (2003) propose models that 1) compare the two reward amounts to determine whether they are similar, 2) compare the similarity of the two time delays, and then 3) make a decision based on these similarity judgments. Here, I tested discounting models against attribute-based …

Voluntary Food Sharing In Pinyon Jays: The Role Of Reciprocity And Dominance, Juan F. Duque, Jeffrey R. Stevens

Jeffrey Stevens Publications

Food sharing offers a clear example of prosocial behavior, in which one individual’s actions benefit another. Researchers have proposed a range of hypotheses that explain why food sharing may occur among unrelated individuals. Two such hypotheses, reciprocity and dominance, have been tested in many species, including fish, corvids, rats, bats, and primates, showing that (1) recipients sometimes reciprocate sharing back to previous donors and (2) dominant individuals share more than subordinates. Although primates dominate the study of prosocial behavior, active donation of food is actually quite rare in primates. In contrast, several corvid species spontaneously share food much more frequently. …

Statistical Analyses Of The Resilience Function, Joseph W. Houpt, Daniel R. Little

Psychology Faculty Publications

The extent to which distracting information influences decisions can be informative about the nature of the underlying cognitive and perceptual processes. In a recent paper, a response time-based measure for quantifying the degree of interference (or facilitation) from distracting information termed resilience was introduced. Despite using a statistical measure, the analysis was limited to qualitative comparisons between different model predictions. In this paper, we demonstrate how statistical procedures from workload capacity analysis can be applied to the new resilience functions. In particular, we present an approach to null-hypothesis testing of resilience functions and a method based on functional principal components …

A High-P/Low-P Procedure To Improve Recall Memory In Elderly Patients With Mild To Moderate Cognitive Impairment, Dawn Amber Seefeldt, Daniel Houlihan, Jeffrey Buchanan

Psychology Department Publications

The objective of this study was to demonstrate the effectiveness of implementing two types of high-probability of naming/low-probability of naming procedures to improve object recall memory in elderly individuals with cognitive impairment. The procedures involved the use of directives for recall compliance with a demonstrated high rate of compliance followed by embedded directives with a demonstrated low rate of recall. Two elderly subjects in states of cognitive decline were used in this demonstration. Results indicated positive outcomes with both procedures. Recall-based interventions were more effective than recognition-based procedures.

The Domain Specificity Of Intertemporal Choice In Pinyon Jays, Jeffrey R. Stevens, Bryce Kennedy, Dina Morales, Marianna Burks

Jeffrey Stevens Publications

When choosing between a piece of cake now versus a slimmer waistline in the future, many of us have difficulty with self-control. Food-caching species, however, regularly hide food for later recovery, sometimes waiting months before retrieving their caches. It remains unclear whether these long-term choices generalize outside of the caching domain. We hypothesized that the ability to save for the future is a general tendency that cuts across different situations. To test this hypothesis, we measured and experimentally manipulated caching to evaluate its relationship with operant measures of self-control in pinyon jays (Gymnorhinus cyanocephalus). We found no correlation …

Why Babies Do Not Feel Pain, Or: How Structure-Derived Functional Interpretations Can Go Wrong, Helmut Segner

Animal Sentience

The response to pain involves a non-conscious, reflexive action and a conscious perception. According to Key (2016), consciousness — and thus pain perception — depends on a neuronal correlate that has a “unique neural architecture” as realized in the human cortex. On the basis of the “bioengineering principle that structure determines function,” Key (2016) concludes that animal species such as fish, which lack the requisite cortex-like neuroanatomical structure, are unable to feel pain. This commentary argues that the relationship between brain structure and brain function is less straightforward than suggested in Key’s target article.

Music And Memory: A Qualitative Look At How Music Affects Episodic Memory, Jonathan A. Coad

Honors Undergraduate Theses

This study was designed to examine qualitative data regarding gender and age differences about significant life events that are recalled when music is remembered. Two groups of participants were recruited, younger adults (M = 19.78, SD = 4.99) and older adults (M = 49.31, SD = 8.72). Data were collected by creating a survey and allowing participants to choose whichever songs, from their own experience, they like and asking them to list detailed memories that are attached to the song. Using the Linguistic Inquiry Word Count (2015) software, data was coded into categories of word count, positive and negative emotions, …

Perception Of Facial Expressions In Social Anxiety And Gaze Anxiety, Aaron Necaise

Honors Undergraduate Theses

This study explored the relationship between gaze anxiety and the perception of facial expressions. The literature suggests that individuals experiencing Social Anxiety Disorder (SAD) might have a fear of making direct eye contact, and that these individuals also demonstrate a hypervigilance towards the eye region. It was thought that this increased anxiety concerning eye contact might be related to the tendency of socially anxious individuals to mislabel emotion in the faces of onlookers. A better understanding of the cognitive biases common to SAD could lead to more efficient intervention and assessment methods. In the present study, the Depression Anxiety Stress …
