If It Looks Like A Duck: Fish Fit The Criteria For Pain Perception, Julia E. Meyers-Manor Jan 2018

If It Looks Like A Duck: Fish Fit The Criteria For Pain Perception, Julia E. Meyers-Manor

Animal Sentience

Whereas we have denied the experience of pain to animals, including human babies, the evidence is becoming clearer that animals across a variety of species have the capacity to feel pain (Bellieni, 2012). As converging findings are collected from pain studies and the study of cognition, it is becoming harder to deny that fish are among the species that do feel pain.


Defining Denial And Sentient Seafood, Jennifer Jacquet Jan 2018

Defining Denial And Sentient Seafood, Jennifer Jacquet

Animal Sentience

Sneddon et al. address the scientists who reject the empirical evidence on fish sentience, calling them “sceptics” and their work “denial”. This is the first article to frame the question of fish sentience in these terms, and it provides an obvious opening for social science and humanities research in the science of fish sentience. It is also worth asking what practical changes in the lives of fish might arise from the mounting evidence of their sentience. I suggest that the relationship between sentience and our sense of moral obligation is not as clear as we often assume.


Sentience: All Or None Or Matter Of Degree?, Loren Martin, Robert Gerlai Jan 2018

Sentience: All Or None Or Matter Of Degree?, Loren Martin, Robert Gerlai

Animal Sentience

The question of whether fish feel pain is muddied by anthropomorphic thinking. Comparing biological phenomena in two species should be informed by the criteria for good animal models: face validity, construct validity and predictive validity. Viewed through this lens, we argue that fish do feel pain and may possess some level of sentience. Evolutionary relatedness, hence similarities and differences between species (fish and humans in this case), are not about black vs. white but about shades of grey.


Degrees Of Sentience?, Jonathan Birch Jan 2018

Degrees Of Sentience?, Jonathan Birch

Animal Sentience

I focus on the possibility of sentience in zebrafish larvae. The evidence here prompts two intuitive reactions that are difficult to reconcile: the reaction that larvae, if sentient, should be protected in some way, and the reaction that larvae, if capable of nociception, should be used as replacements for adults. Both reactions are reasonable, but they can be reconciled only by constructing a framework for assigning degrees of protection in proportion to degrees of sentience.


The Human Nervous System Is Not The Gold Standard For Pain, Riccardo Manzotti Jan 2018

The Human Nervous System Is Not The Gold Standard For Pain, Riccardo Manzotti

Animal Sentience

The basis of pain could be the causal nexus between one’s phylogenetic/ontogenetic history and one’s behavior. It might turn out that the neural implementation is immaterial to the instantiation of pain. Widely different neural structures may token the same pain-type, and nearly identical neural structures may token different types.


Time To (Finally) Acknowledge That Fish Have Emotionality And Pain, Konstantin A. Demin, Anton M. Lakstygal, Allan V. Kalueff Jan 2018

Time To (Finally) Acknowledge That Fish Have Emotionality And Pain, Konstantin A. Demin, Anton M. Lakstygal, Allan V. Kalueff

Animal Sentience

The increasing work using fish as a model organism calls for a better understanding of their sentience. While growing evidence suggests that pain and emotionality exist in zebrafish, many deniers continue to ignore the evidence. Here we revisit the main conceptual breakthroughs in the field that argue clearly for pain and emotionality. We call for an end to denial and a focus on studying the mechanisms of fish pain and emotionality, and their translational relevance to human conditions.


Defining Pain And Painful Sentience In Animals, Edgar T. Walters Jan 2018

Defining Pain And Painful Sentience In Animals, Edgar T. Walters

Animal Sentience

Sentience is essential to most definitions of pain, including a detailed definition invoked by Sneddon et al. to argue that adult and perhaps larval fish feel pain. Because proving painful sentience in non-human animals is not feasible, multiple lines of indirect evidence are needed to implicate pain. This commentary examines the list of 17 criteria used by Sneddon et al. to conclude that fish have conscious pain. The criteria include tests of nociceptive, motivational, and cognitive properties useful for revealing pain-like states that can be understood biologically and be related evolutionarily to human pain. However, additional research is needed to …


Nocifensive Behavior As Evidence For Sentient Pain In Fish, Marissol Leite Da Silva, Caio Maximino, Diógenes Henrique Siqueira-Silva Jan 2018

Nocifensive Behavior As Evidence For Sentient Pain In Fish, Marissol Leite Da Silva, Caio Maximino, Diógenes Henrique Siqueira-Silva

Animal Sentience

Fish nocifensive behavior can be studied and understood similarly to the way pain is studied and understood in more advanced vertebrates. Nocifensive behavior is a behavioral and physiological response to a noxious stimulus that leads to the fish avoiding it in the future. This behavioral flexibility is an important criterion for inferring pain sentience in fish. Modulation of the nocifensive behavior by anxiety, fear, or stress has already been demonstrated in zebrafish. The affective experiences of fish will not be identical to those of human beings, clearly. Empirical research will need to ascertain how similar they are.


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 Jan 2018

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

Animal Sentience

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.


Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns Jan 2018

Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns

Animal Sentience

Domestic dogs are highly social and have been shown to be sensitive not only to the actions of humans and other dogs but to the interactions between them. We used the C-BARQ scale to estimate dogs’ aggressiveness, and we used noninvasive brain imaging (fMRI) to measure activity in their amygdala (an area involved in aggression). More aggressive dogs had more amygdala activation data while watching their caregiver give food to a realistic fake dog than when they put the food in a bucket. This may have some similarity to human jealousy, adding to a growing body of evidence that differences …


Finding The Green-Eyed Monster In The Brain Of A Dog, Peter Singer Jan 2018

Finding The Green-Eyed Monster In The Brain Of A Dog, Peter Singer

Animal Sentience

That dogs show behavior suggestive of jealousy has long been known and has been demonstrated under controlled conditions. Cook et al. have now shown arousal in the amygdala when dogs see a caregiver feeding another dog. This finding has ethical significance in two respects. First, the consideration shown by the investigators for the welfare of their experimental subjects sets an example for other researchers using animals. Second, the greater understanding of the emotional lives of animals should lead to more concern for their needs.


Jealousy, Competition, Or A Contextual Cue For Reward?, Thomas R. Zentall Jan 2018

Jealousy, Competition, Or A Contextual Cue For Reward?, Thomas R. Zentall

Animal Sentience

Emotions are difficult to assess, even in humans. The attribution of jealousy in an animal like a dog is especially difficult because performance of a particular behavior in the context of another animal receiving a reward may not be easily distinguishable from intra-species competition or simply a response to a contextual cue for the availability of reward. The authors provide distinguishing evidence in the form of fMRI data to show that in the presence of a “fake” dog being fed, there is bilateral activation in the amygdala, an area associated with anxiety, anger, fear, and even jealousy in humans.


What Can The Social Emotions Of Dogs Teach Us About Human Emotions?, Dean Mobbs Jan 2018

What Can The Social Emotions Of Dogs Teach Us About Human Emotions?, Dean Mobbs

Animal Sentience

It has long been believed that social emotions such as guilt and jealousy are only expressed in humans. In the case of jealousy, its adaptive value has been linked to the prevention of sexual infidelity or fairness. So why would dogs feel jealousy? I suggest that understanding how social emotions have been bred into dogs can help us understand our own emotions, including their functionality — and potentially their mechanisms.


Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell Jan 2018

Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell

Animal Sentience

Jealousy, or at least aggression, can be observed in dogs using neuroimaging techniques, but this response attenuates quickly following repeated exposure to the aggression-inducing stimulus. This may have a practical application. Early socialisation as a puppy, and habituation as an adult dog, could help prevent undesirable behaviours such as predatory behaviour. It is unclear whether these processes are the same, and affected only by the dog’s age. Neuroimaging could help us understand whether the same neurological processes underlie socialisation and habituation, and whether self-rewarding behaviours such as predatory behaviour could be stopped using socialisation/habituation techniques.


On Jealousy, Envy, Sex Differences And Temperament In Humans And Dogs, Eddie Harmon-Jones, Sylvia K. Harmon-Jones Jan 2018

On Jealousy, Envy, Sex Differences And Temperament In Humans And Dogs, Eddie Harmon-Jones, Sylvia K. Harmon-Jones

Animal Sentience

Cook, Prichard, Spivak, and Berns (2018) find that dogs’ levels of trait aggression are positively correlated with their amygdala activation when observing their caregivers giving a food to a fake dog. The authors conclude that this may provide neural evidence in dogs for the experience of jealousy, an emotion that some psychologists consider to be unique to humans. Here we explain the difference between the emotions of jealousy and envy, suggesting some ideas for future experiments that may help disentangle the experience of jealousy from that of envy in dogs. We also propose ideas for future research that may yield …


Inferring Emotion From Amygdala Activation Alone Is Problematic, Thomas F. Denson Jan 2018

Inferring Emotion From Amygdala Activation Alone Is Problematic, Thomas F. Denson

Animal Sentience

Cook et al. investigated neural responses in domestic dogs in an experiment designed to elicit jealousy. Relative to a control condition, watching the dogs’ caregivers feed a fake dog activated the amygdala bilaterally. Dogs rated higher in dog-directed aggressiveness showed larger initial amygdala activation. Amygdala activity in this context is insufficient evidence to infer that the dogs experienced jealousy or even negative affect. The experimental design does not provide an adequate level of control to infer the presence of jealousy.


Can A Dog Be Jealous?, Yaoguang Jiang, Annamarie W. Huttunen, Michael L. Platt Jan 2018

Can A Dog Be Jealous?, Yaoguang Jiang, Annamarie W. Huttunen, Michael L. Platt

Animal Sentience

Whether humans alone experience complex emotions like jealousy or envy remains hotly debated, partly because of the difficulty of measuring them without a verbal report. Cook, Berns and colleagues use functional brain imaging to identify in dogs neural responses very similar to those evoked by jealousy in humans. When dogs see their caregiver reward a facsimile dog, their amygdala is activated and the strength of this response predicts aggressive behavior — just as jealousy leads to aggression in humans. The authors conclude that dogs feel something very similar to human jealousy. This novel and creative study tackles one of the …


Jealousy? Or Just Hostility Toward Other Dogs? The Risks Of Jumping To Conclusions, James A. Serpell Jan 2018

Jealousy? Or Just Hostility Toward Other Dogs? The Risks Of Jumping To Conclusions, James A. Serpell

Animal Sentience

Cook et al. (2018) provide a fascinating demonstration of amygdala activation in dogs when they witnessed their owners giving food to another (fake) dog, but not when they placed food in a bucket. Dogs’ neurological responses were positively correlated with their reported levels of ‘dog-directed aggression’ as measured by the C-BARQ, and dogs with initially strong amygdala responses habituated on subsequent trials. The authors interpret their findings as possible evidence for an emotion akin to jealousy in dogs. However, alternate interpretations involving either dog aggression/fear or emotional responses to food seem more plausible and avoid the welfare risks associated with …


Fake Or Not: Two Prerequisites For Jealousy, Juliane Bräuer, Federica Amici Jan 2018

Fake Or Not: Two Prerequisites For Jealousy, Juliane Bräuer, Federica Amici

Animal Sentience

Cook and colleagues (2018) use a novel approach to test jealousy in dogs. Although such a non-invasive approach is more than welcome in comparative research, several methodological shortcomings limit the impact of this study. We briefly outline two main problems. (1) There is no evidence that the fake dogs in the study were perceived as real, and thus as social rivals, which would be a prerequisite for jealousy. (2) It is questionable whether dogs generally show the cognitive prerequisites for jealousy, such as attentiveness toward a social rival, the ability to understand intentions, and a sense of fairness. We suggest …


Only The Human Brain Has The Cognitive Capacity For Jealousy, Donatella Marazziti Jan 2018

Only The Human Brain Has The Cognitive Capacity For Jealousy, Donatella Marazziti

Animal Sentience

Jealousy is exclusively a human phenomenon because nonhuman animals lack the brain structures regulating the higher processes underlying jealousy.


Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo Jan 2018

Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo

Animal Sentience

What is needed to make meaningful claims about an animal’s capacity for subjective experience? Cook et al. (2018) attempt to study jealousy in dogs by placing them in a particular context and then seeing whether they display a particular brain state. We argue that this approach to studying jealousy falls short for two related reasons. First, the relationship between jealousy and the selected context is unclear. Second, the relationship between jealousy and the selected brain state (indeed, any single brain state) is unclear. These and other issues seriously limit what this study can show. It is important not to see …


Uncovering The Lost Knowledge Of The Imagination In Films, Seda, Daniel A. Jan 2018

Uncovering The Lost Knowledge Of The Imagination In Films, Seda, Daniel A.

Journal of Conscious Evolution

Films have forever changed the way in which humans perceive reality and have provided significant opportunities to spread knowledge in ways that are both entertaining and deceptive. Uncovering the lost knowledge of the imagination shifts an individual’s perceptions of a shared experience and exposes film’s persuasive power to penetrate the psyche. This paper explores the constitutions of reality and how humans are able to tap into other realms of consciousness through mediums of creative expression. Topics such as the origins of life, the hidden knowledge of secret societies, and the burgeoning full disclosure movement for truth are discussed as a …


The Role Of Sleep Deprivation And Fatigue In The Perception Of Task Difficulty And Use Of Heuristics, Mindy Engle-Friedman, Gina Marie Mathew, Anastasia Martinova, Forrest Armstrong, Viktoriya Konstantinov Jan 2018

The Role Of Sleep Deprivation And Fatigue In The Perception Of Task Difficulty And Use Of Heuristics, Mindy Engle-Friedman, Gina Marie Mathew, Anastasia Martinova, Forrest Armstrong, Viktoriya Konstantinov

Publications and Research

Objectives: This study investigated the effects of sleep deprivation on perception of task difficulty and use of heuristics (mental shortcuts) compared to naturally-experienced sleep at home. Methods: Undergraduate students were screened and assigned through block-random assignment to Naturally-Experienced Sleep (NES; n=19) or Total Sleep Deprivation (TSD; n=20). The next morning, reported fatigue, perception of task difficulty, and use of “what-is-beautiful-is-good,” “greedy algorithm,” and “speed-accuracy trade-off ” heuristics were assessed. Results: NES slept for an average of 354.74 minutes (SD=72.84), or 5.91 hours. TSD rated a reading task as significantly more difficult and requiring more time than NES. TSD was …


Emotion In The Common Model Of Cognition, Othalia Larue, Robert West, Paul Rosenbloom, Christopher L. Dancy, Alexei V. Samsonovich, Dean Petters, Ion Juvina Jan 2018

Emotion In The Common Model Of Cognition, Othalia Larue, Robert West, Paul Rosenbloom, Christopher L. Dancy, Alexei V. Samsonovich, Dean Petters, Ion Juvina

Faculty Journal Articles

Emotions play an important role in human cognition and therefore need to be present in the Common Model of Cognition. In this paper, the emotion working group focuses on functional aspects of emotions and describes what we believe are the points of interactions with the Common Model of Cognition. The present paper should not be viewed as a consensus of the group but rather as a first attempt to extract common and divergent aspects of different models of emotions and how they relate to the Common Model of Cognition.


Log Kya Kahenge: Psychological Well-Being And Perceived Stigma In The South Asian American Community, Khushboo Jain Jan 2018

Log Kya Kahenge: Psychological Well-Being And Perceived Stigma In The South Asian American Community, Khushboo Jain

Pomona Senior Theses

Current research has independently studied depression, stigma, and coping mechanisms in relation to culture, yet the effects of perceived stigma on the relationship between depression and control coping are heavily understudied. Typically, studies have broadly focused on comparing eastern and western cultures, but have not analyzed how populations with mixed cultural influences experience depression and stigma and further engage in control coping mechanisms. This study thus explores how perceived stigma moderates the relationship between depressive symptoms and control coping mechanisms for South Asian Americans. The study hypothesizes that the level of perceived stigma will moderate the relationship between depression and …


An Electrophysiological Study On Sex-Related Differences In Emotion Perception, Natalie Wiswesser, James Houston Phd, Philip Allen Phd Jan 2018

An Electrophysiological Study On Sex-Related Differences In Emotion Perception, Natalie Wiswesser, James Houston Phd, Philip Allen Phd

Williams Honors College, Honors Research Projects

The purpose of this research project was examine the following question: Do men and women respond differently, on a neurophysiological level, to stimuli that elicit an emotional valence? Participants completed an emotional expression face identification task in which participants made speeded responses to angry, happy, and neutral emotional faces. Behavioral and event-related potential (ERP) methods were utilized to examine emotion processing differences between females and males and whether those differences were associated with emotional arousal or emotion regulation differences. Results indicated that females and males did not differ in accuracy or response time. Furthermore, there were no observable differences in …


Face Perception And Identification, Audrey Aamot Jan 2018

Face Perception And Identification, Audrey Aamot

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The present research aimed to examine the combined effects of the own-race effect and own-age bias in relation to memory performance. The own-race effect suggests that individuals perform better when asked to remember faces of the same race as their own, as opposed to faces of a different race (Meissner, Brigham & Butz, 2005). Own-age bias is a tendency for individuals to perform better when remembering faces from the same age group as their own (Rhodes & Anastasi, 2005, 2012). It was hypothesized that when recognizing faces of a different age and race, memory accuracy would be worse, when compared …


Predicting Similarity Judgments In Intertemporal Choice With Machine Learning, Jeffrey R. Stevens, Leen-Kiat Soh Jan 2018

Predicting Similarity Judgments In Intertemporal Choice With Machine Learning, Jeffrey R. Stevens, Leen-Kiat Soh

Jeffrey Stevens Publications

Similarity models of intertemporal choice are heuristics that choose based on similarity judgments of the reward amounts and time delays. Yet, we do not know how these judgments are made. Here, we use machine-learning algorithms to assess what factors predict similarity judgments and whether decision trees capture the judgment outcomes and process. We find that combining small and large values into numerical differences and ratios and arranging them in tree-like structures can predict both similarity judgments and response times. Our results suggest that we can use machine learning to not only model decision outcomes but also model how decisions are …


Heterogeneity And Parsimony In Intertemporal Choice, Michel Regenwetter, Daniel R. Cavagnaro, Anna Popova, Ying Guo, Chris Zwilling, Shiau Hong Lim, Jeffrey R. Stevens Jan 2018

Heterogeneity And Parsimony In Intertemporal Choice, Michel Regenwetter, Daniel R. Cavagnaro, Anna Popova, Ying Guo, Chris Zwilling, Shiau Hong Lim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Behavioral theories of intertemporal choice involve many moving parts. Most descriptive theories model how time delays and rewards are perceived, compared, and/or combined into preferences or utilities. Most behavioral studies neglect to spell out how such constructs translate into heterogeneous observable choices. We consider several broad models of transitive intertemporal preference and combine these with several mathematically formal, yet very general, models of heterogeneity. We evaluate 20 probabilistic models of intertemporal choice using binary choice data from two large-scale experiments. Our analysis documents the interplay between heterogeneity and parsimony in accounting for empirical data: We find evidence for heterogeneity across …


Managing Employee Attitude For A Successful Information System Implementation: A Change Management Perspective, Smita Chaudhry Jan 2018

Managing Employee Attitude For A Successful Information System Implementation: A Change Management Perspective, Smita Chaudhry

Journal of International Technology and Information Management

In the last three decades, there has been considerable advancement in the design of information systems used in organizations. Information systems facilitate critical organizational activities like recording and processing of business transactions, analyzing complex and large sets of data and generating management and executive level reports. However, their adoption is generally fraught with challenges because of the negative attitude of employees to the impending change in their work life. Taking into account the enormous investment of cost, time and effort in information system implementation, it is imperative for organizations to recognize and influence employee attitude from the very beginning to …
