Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan Jan 2019

Mirror Neurons And Humanity’S Dark Side, Gisela Kaplan

Animal Sentience

The last two decades have revealed brain mechanisms in birds and primates showing that, contrary to earlier prejudices, some birds can do things (cognitive and affective) on par with or even better than great apes and humans. The old dichotomies are breaking down; but the dark side is that these insights come at a time in the Anthropocene when humans have caused and continue to cause mass extinctions.


Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez Jan 2019

Humans May Be Unique And Superior — And That Is Irrelevant, Eze Paez

Animal Sentience

Chapman & Huffman argue that, because humans are neither unique nor superior to the other animals, cruelty to animals is not justified. Though I agree with their conclusion, I do not think their argument works. Many human beings do have some capacities that animals do not have and are greater in some respects, in the sense of having superior abilities. It is a better argument to deny that any of that is morally relevant. Sentience suffices for moral consideration, and for deriving a moral duty not to harm other animals and to assist them when they are in need.


Taking Exception To Human Exceptionalism, Carrie P. Freeman Jan 2019

Taking Exception To Human Exceptionalism, Carrie P. Freeman

Animal Sentience

Chapman & Huffman refute common claims used to justify human species distinctions, and they critique the animal cruelty that has resulted from this privileged status. I raise related questions for further study of the roots of human exceptionalism and about whether aspiring to be more like our fellow animals might be part of the solution.


The Importance Of Research Applicability, Krista Mclennan Jan 2019

The Importance Of Research Applicability, Krista Mclennan

Animal Sentience

Marino & Merskin’s (2019) review contains key information about the complexity of sheep and their intelligence level, but lacks practical application. The key to making any long-term changes to sheep welfare at an industry level is by generating research that is practically relevant to the sector. The practical application of research should be considered at the design stage and in consultation with producers. Additionally, thought needs to be given to how the practical application of the research will be transferred to those people directly involved in animal care (e.g., producers, stockpersons, etc.). Focusing on the practical relevance and application of …


Time To Vary The Formula, Jon Mallatt Jan 2019

Time To Vary The Formula, Jon Mallatt

Animal Sentience

In the past few years, Marino and her colleagues have written a series of comprehensive and helpful review articles on the cognitive, emotional, and social complexity of pigs, chickens, cows, and most recently, sheep. These articles are similarly structured, even formulaic, which has benefits but also limitations. Here, I point out the limitations in order to suggest new directions and contributions for the authors in the future.


Guilty As Charged, Sergio M. Pellis Jan 2019

Guilty As Charged, Sergio M. Pellis

Animal Sentience

Sheep have had a bad rap with regard to their behavioral capabilities, and to a large extent, that negative view of sheep has arisen from our failure as human observers to view the world from the perspective of the sheep themselves. Studies sensitive to what sheep identify as of value in the world have revealed a different picture: sheep have cognitive, emotional and social complexity beyond our crude stereotype. Clearly, what we need to do is to evaluate non-human animals on their own terms and not as a reflection of ourselves.


Sheep Complexity Outside The Laboratory, Cheryl Abbate Jan 2019

Sheep Complexity Outside The Laboratory, Cheryl Abbate

Animal Sentience

Marino & Merskin’s review shows that sheep are intelligent and highly social but their methodology has some shortcomings. I describe five problems with reviewing only the academic and scientific literature and suggest how one might provide an even more compelling case for the complexity of sheep minds.


Sacrificial Lambs, Clive Phillips Jan 2019

Sacrificial Lambs, Clive Phillips

Animal Sentience

Sheep evolved from the mouflon as mountain animals, able to escape predation by leaping between rock ledges. Their defense was their agility. Humans brought them to the plains, where the agility was less useful, but their lack of aggression, speed or weaponry against predators made them a prime target to become one of man’s meat providers. A perfect animal in many ways, with extraordinary perceptive powers and some remarkable cognitive skills, they are often treated with complete disregard for their welfare. Yet sheep themselves won’t tell us this, for a sheep that alerted others to its weakness really would be …


Positive Sentience Is Underrated, Teya Brooks Pribac Jan 2019

Positive Sentience Is Underrated, Teya Brooks Pribac

Animal Sentience

My commentary focuses on two aspects of ovine (well-)being considered in the review: the developmental context and (un)fulfilled potentialities.


Using Sheep Psychology To Guide Sheep Policy, Ralph Adolphs Jan 2019

Using Sheep Psychology To Guide Sheep Policy, Ralph Adolphs

Animal Sentience

Marino & Merskin’s valuable review of the literature on sheep cognition shows how entrenched common views of these animals’ mental lives are disputed by the research literature. Yet the evidence they muster faces three challenges that their target article does not discuss: (1) the behavioral tasks are strongly anthropocentric; (2) neuroscientific data are absent; and (3) applications are not discussed. I touch on all three of these here.


Octopus Umwelt Or Umwelten?, Luis H. Favela Jan 2019

Octopus Umwelt Or Umwelten?, Luis H. Favela

Animal Sentience

Even if its intelligent behaviors are the product of decentralized control systems, Mather argues that the octopus has an “Umwelt,” and, thus, a mind. I argue that Umwelt does not provide a conceptual basis for understanding the octopus as having a mind. First, Umwelt does not refer only to an organism’s perceptual abilities. Second, in providing evidence for decentralized control systems that underlie intelligent behaviors, Mather makes a case against an octopus Umwelt. Instead, the octopus is more akin to a collection of systems, or Umwelten, than a single system with an Umwelt.


What Is Good For An Octopus?, Heather Browning Jan 2019

What Is Good For An Octopus?, Heather Browning

Animal Sentience

Mather (2019) has brought together the current empirical research in support of the claim that octopuses possess minds; and the weight of the evidence does appear to support octopus sentience. Being sentient means an organism has welfare concerns, a subjective experience of life that can go well or poorly. Protecting welfare requires knowing what conditions will have a positive or negative impact. Understanding what is in the mind of an octopus will give us valuable insight into what is good for an octopus.


The Octopus: A Beautiful (But Disorganized) “Mind”, Jon Mallatt Jan 2019

The Octopus: A Beautiful (But Disorganized) “Mind”, Jon Mallatt

Animal Sentience

Mather (2019) presents convincing evidence that octopuses have minds, but in the first 85% of the target article, the evidence does not come through very clearly because it is hidden by other information and by problems with the paper’s organization. I propose ways to build a tighter argument in the author’s Response to the Commentaries.


The Perfecting Of The Octopus, Ila France Porcher Jan 2019

The Perfecting Of The Octopus, Ila France Porcher

Animal Sentience

Cephalopods split away from the phylogenetic tree about half a billion years ago, and octopus evolution has been accelerated by an extremely low survival rate. This helps explain why this unusual animal presents qualities found in no other. It has a radially organized nervous system with a processing centre for each of its eight tentacles. Yet, although this might suggest that each tentacle has its own centre of consciousness, it remains just one animal, with one mouth to feed, and one life to lose, and it behaves as if it is centrally controlled. Its capacity for a range of intelligent …


‘Mind’ Is An Ill-Defined Concept: Considerations For Future Cephalopod Research, Alexandra Schnell, Giorgio Vallortigara Jan 2019

‘Mind’ Is An Ill-Defined Concept: Considerations For Future Cephalopod Research, Alexandra Schnell, Giorgio Vallortigara

Animal Sentience

Scientific discussions about the ‘mind’ of an octopus are empirically vacuous and should be confined to folk psychology. This form of labelling is unhelpful for science and should be replaced by specific mechanistic accounts of behavior and associated neural structures, which are amenable to rigorous scientific investigation. Mather provides a detailed review of octopus behavior, but rather than making unquantifiable assumptions about what orchestrates octopus behavior, efforts should focus on investigating cognitive mechanisms that can be measured. In this commentary, we outline two lines of research that include quantifiable methods to facilitate a more robust understanding of cephalopod behaviors and …


Octopus Sentience: Three Criteria, Alix Noël-Guéry Jan 2019

Octopus Sentience: Three Criteria, Alix Noël-Guéry

Animal Sentience

The first question to ask is whether octopuses are sentient, so that, if so, they can be protected. Three consensual criteria to evaluate animal sentience can be applied to the octopus. Octopuses meet all three of them.


Granting Political Representation To Non-Humans, Joe Gray Jan 2019

Granting Political Representation To Non-Humans, Joe Gray

Animal Sentience

This commentary discusses the representation of individuals versus populations — human and nonhuman, present and future — in Treves et al.’s proposed trusteeship for futurity. Terminological questions are also discussed.


Reconciling Just Preservation, Shelley M. Alexander Jan 2019

Reconciling Just Preservation, Shelley M. Alexander

Animal Sentience

Treves et al.’s target article can play an important role in reconciling the needs of future generations and non-human animals in conservation. Human capacities are adequate for interpreting and defining many non-human animal needs. Worldviews are more complex, however, and conservation science, like the target article itself, suffers from a lack of diversity and inclusiveness. This may pose practical impediments to realizing just preservation.


Human Interests, Helen Tiffin Jan 2019

Human Interests, Helen Tiffin

Animal Sentience

Treves et al.’s proposal is welcome, but it will have to face at least four challenges: the interconnectedness of the human and the nonhuman portions of the biosphere, conflicts of interest, human overpopulation, and capitalism itself.


Just Preservation, Adrian Treves, Francisco J. Santiago-Ávila, William S. Lynn Jan 2019

Just Preservation, Adrian Treves, Francisco J. Santiago-Ávila, William S. Lynn

Animal Sentience

We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate change. We argue that the interests and well-being of non-humans, youth, and future generations of both human and non-human beings (futurity) have too long been ignored in consensus-based, anthropocentric conservation. Consensus-based stakeholder-driven processes disadvantage those absent or without a voice and allow current adult humans and narrow, exploitative interests to dominate decisions about the use of nature over its preservation for futurity of all life. We propose that authentically non-anthropocentric …


The Problem Is Not Discourses Of Production; It Is Production Itself, Sean Hermanson Jan 2019

The Problem Is Not Discourses Of Production; It Is Production Itself, Sean Hermanson

Animal Sentience

The mistreatment of sheep is not because of fables, stereotypes, unconscious cultural paradigms, our collective consciousness, anthropocentricism, human arrogance, or our drive to dominate. Nonetheless, protections for sheep used in research and agriculture ought to be strengthened.


Sheep Are Sentient, But Not Identical, Alison Hanlon Jan 2019

Sheep Are Sentient, But Not Identical, Alison Hanlon

Animal Sentience

Marino & Merskin (M&M) provide a timely reminder that sheep have advanced cognitive abilities, but do we still have to provide evidence to justify animal sentience? In the EU, regulations are designed to support farm animal welfare. Whilst the regulations are imperfect, they do emphasize behavioural needs and other concepts relevant to sentience. The persistence of sheep welfare issues such as lamb mortality indicates that regulations may not be achieving their desired goal. We can quibble about the science described by M&M yet reach the same conclusion: sheep (lambs, ewes and rams) are not all identical, but they are all …


Is Human Uniqueness Fake News?, Sean Hermanson Jan 2019

Is Human Uniqueness Fake News?, Sean Hermanson

Animal Sentience

The world and its troubles don't need unfounded denials of human uniqueness.


Reflections On Sheep Rearing, Joyce D'Silva Jan 2019

Reflections On Sheep Rearing, Joyce D'Silva

Animal Sentience

Sheep rearing has an incredibly long history. Sometimes this alone can give credibility and status to a human practice. In the twenty-first century, it may be time to reassess our treatment of sheep and their place in nature. “Just because we’ve always done it” no longer has validity by itself. There are many other human practices which used to be accepted widely in certain societies and which we now may find abhorrent. With sheep intelligence now rightly regarded as an acceptable area of research within the academic community, it is a good time to reflect on our treatment of these …


Smart Sheep Need More Protection, Michael L. Woodruff Jan 2019

Smart Sheep Need More Protection, Michael L. Woodruff

Animal Sentience

The target article unequivocally establishes that sheep are far more intelligent and cognitively sophisticated than is generally acknowledged. For this reason, the authors advocate for significantly more stringent regulation of agricultural and research practices when sheep are used. I briefly review the existing US regulations governing the use of sheep in research and discuss the extent to which they are applied to sheep. I then discuss weaknesses in the current regulations, concluding that they should be changed to mandate housing all research animals in environments that accommodate the psychosocial needs of each species.


Is Knowing Enough To Change Human Attitudes And Actions?, Liv Baker Jan 2019

Is Knowing Enough To Change Human Attitudes And Actions?, Liv Baker

Animal Sentience

Marino & Merskin present evidence on key aspects of cognition, such as theory of mind, learning, emotional valence, and sociality, to make a convincing argument that sheep are due consideration as individual sentient beings. With this information, what will it take to produce a real, meaningful shift in our attitudes and actions towards other animals, including a species as disadvantaged as sheep? What else do we need to know?


The Intelligence Of Sheep, David Gamez Jan 2019

The Intelligence Of Sheep, David Gamez

Animal Sentience

This commentary suggests how recent theories about the predictive brain could help us understand the evidence put forward by Marino & Merskin for intelligence in sheep. I contrast predictive intelligence in sheep with automatic behaviors that do not require intelligence, and I consider the flexibility of sheep intelligence.


A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam Jan 2019

A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam

Animal Sentience

Marino & Merskin’s review sheds light on the complexity of the mind, learning, and cognition of sheep. Readily observable behavior has value in its own right for promoting the well-being of animals. A behavior-analytic approach can add substantially to the understanding of sheep as individuals as well as their learning capacities. The findings can also be applied to arranging their environments to promote their well-being as well as behavioral change in those responsible for their care and management.


Adding Sheep To The Spectrum Of Comparative Psychology, James King Jan 2019

Adding Sheep To The Spectrum Of Comparative Psychology, James King

Animal Sentience

Marino & Merskin’s comprehensive review of cognitive complexity in sheep is a laudable and important contribution to comparative psychology. It is also valuable because it shows promising directions for future research on this neglected species. The relatively small number of neurons in the bovid cerebral cortex indicates that sheep cognitive performance on traditional measures of complex learning is limited. Nevertheless, the social and emotional complexity of sheep underscores the importance of further research into domains including personality and psychological well-being.


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

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

Animal Sentience

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.
