We Don’T Want To Know What We Know, Judith Benz-Schwarzburg

Animal Sentience

Why are humans so ignorant with regard to the fundamental gap between ethical claims and the status quo of the human-animal relationship? To answer this, we should include more psychological and sociological perspectives in our discussions.

Two Fallacies In Comparisons Between Humans And Non-Humans, Don Ross

Animal Sentience

The hypothesis that humans are superior to non-humans by virtue of higher cognitive powers is often supported by two recurrent fallacies: (1) that any competence shown by humans but not by our closest living relatives (apes) must be unique to humans; and (2) that grades of intelligence can be inferred from behavior without regard to motivational structures.

What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy

Animal Sentience

We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.

Is Superiority A Necessary Aspect Of Cruelty?, William H. Edmondson

Animal Sentience

Chapman & Huffman argue that humans inflict cruelty without apparent concern because of their categorization of the victims as inferior. The supposed inferiority of non-human animals can be argued against on the basis of documentation and analysis of behaviour. Humans continue to inflict cruelty on their own and other species. It is not obvious that a sense of superiority is a necessary aspect of cruel behaviour. Nor is it obvious that further enlightenment regarding the cognitive status of non-humans will diminish cruelty.

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

Animal Sentience

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.

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

Animal Sentience

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.

Fish And Plant Sentience: Anesthetized Plants And Fishes Cannot Respond To Stimuli, Ken Yokawa, František Baluška

Animal Sentience

Recent denial of fish sentience is at variance with the fact that all living organisms need environmental awareness in order to survive in a continuously fluctuating environment. Moreover, fish sentience – like plant sentience – is also strongly supported by the sensitivity of fishes and plants to diverse anesthetics.

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

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

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.

Denialism And Muddying The Water Or Organized Skepticism And Clarity? That Is The Question, Ben Diggles, Howard I. Browman

Animal Sentience

The research being commented on here has been criticized and defended in journals. Sneddon et al. (2018) add nothing substantive. We have nothing further to add. Readers are referred to Diggles (2018) and to Browman et al. (2018) for a detailed assessment.

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

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.

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 …

Fish Are Smart And Feel Pain: What About Joy?, Becca Franks, Jeff Sebo, Alexandra Horowitz

Animal Sentience

Sneddon et al. rightly point out that the evidence of fish pain is now so strong and comprehensive that arguments against it have become increasingly difficult to defend in balanced academic discourse. But sentience involves more than just pain. Recent research indicates that fish have an impressive range of cognitive capacities, including the capacity for pleasure, in the form of play and other behaviors likely to involve positively valenced experience. Having made the case for pain, research can now focus on other aspects of fish sentience. Doing so will not only provide a more complete picture of the mental lives …

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.

Preschoolers And Pandas Making Friends: A Journey About Healing From Brain Injury, Barbara Anne Doucette

Museum Studies Projects

Preschoolers that have obtained Non-Accidental Injury (NAI) from familial child abuse are in need of having a unique place for neurorehabilitation in correlation with traditional therapies. My thesis project suggests adding an exhibit annex to an existing giant panda exhibit that will give preschoolers an opportunity to help develop new neuropathways when exposed to mediation and creative activities. Meditation and creative activities are being examined by neuroscientists as an aid in neuroplasticity after brain injury. This thesis reviews the neurotypical preschooler’s milestones and the playful means by which they are achieved. Conjoining the contemporary museums’ and zoological gardens’ outreach to …

Language Experience With A Native-Language Phoneme Sequence Modulates The Effects Of Attention On Cortical Sensory Processing, Valerie L. Shafer, Monica Wagner, Jungmee Lee, Francesca Mingino, Colleen O'Brien, Adam Constantine, Mitchell Steinschneider

Publications and Research

Auditory evoked potentials (AEP) reflect spectro-temporal feature changes within the spoken word and are sufficiently reliable to probe deficits in auditory processing. The current research assessed whether attentional modulation would alter the morphology of these AEPs and whether native-language experience with phoneme sequences would influence the effects of attention. Native-English and native-Polish adults listened to nonsense word pairs that contained the phoneme sequence onsets /st/, /sət/, /pət/ that occur in both the Polish and English languages and the phoneme sequence onset /pt/ that occurs in the Polish language, but not the English language. Participants listened to word pairs within two …

Is Cooperative Memory Special? The Role Of Costly Errors, Context, And Social Network Size When Remembering Cooperative Actions, Jeffrey R. Stevens, Tim Winke

Jeffrey Stevens Publications

Theoretical studies of cooperative behavior have focused on decision strategies, such as tit-for-tat, that depend on remembering a partner’s last choices. Yet, an empirical study by Stevens et al. (2011) demonstrated that human memory may not meet the requirements that needed to use these strategies. When asked to recall the previous behavior of simulated partners in a cooperative memory task, participants performed poorly, making errors in 10–24% of the trials. However, we do not know the extent to which this task taps specialized cognition for cooperation. It may be possible to engage participants in more cooperative, strategic thinking, which may …

The Inconvenient Truth About Thinking Chickens, Lori Marino

Animal Sentience

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 …

Combined Mnemonic Strategy Training And High-Definition Transcranial Direct Current Stimulation For Memory Deficits In Mild Cognitive Impairment, Benjamin M. Hampstead, Krishnankutty Sathian, Marom Bikson, Anthony Y. Stringer

Publications and Research

Introduction: Memory deficits characterize Alzheimer’s dementia and the clinical precursor stage known as mild cognitive impairment. Nonpharmacologic interventions hold promise for enhancing functioning in these patients, potentially delaying functional impairment that denotes transition to dementia. Previous findings revealed that mnemonic strategy training (MST) enhances long-term retention of trained stimuli and is accompanied by increased blood oxygen level–dependent signal in the lateral frontal and parietal cortices as well as in the hippocampus. The present study was designed to enhance MST generalization, and the range of patients who benefit, via concurrent delivery of transcranial direct current stimulation (tDCS).

Methods: This protocol describes …

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space beyond the …

Behavioral Responses To Pulses Of Light In The Longfin Inshore Squid, Doryteuthis Pealeii (Lesueur, 1821), Stavros P. Hadjisolomou

Dissertations, Theses, and Capstone Projects

The coleoid cephalopods (octopus, squid, and cuttlefish) are masters of rapid, adaptive camouflage. Unlike the slower hormonal chromatophore control of flatfish and chameleons, coleoid mollusks can change body patterns in milliseconds. Visual camouflage in coleoids is driven by a sensorimotor system consisting of visual input of their surroundings, a sophisticated central nervous system for information processing, and a neuromuscular control for body patterning. Motor neurons selectively activate millions of muscles, alternately expanding and reducing the pigmented chromatophores to generate visible brown, red, orange and yellow patterns on the skin. Below the chromatophore-layered skin are two types of reflecting cells, iridophores …

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

Theses and Dissertations

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G₂ = 78.10, p < 0.001).

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Raising Consciousness About Chicken Consciousness, Bernard Rollin

Animal Sentience

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.
