Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Animal Sentience
Crump et al. (2022) offer a well-argued example of an essential development: a rigorous framework for assessing sentience from the perspective of moral concern over an agent’s welfare. Current and forthcoming developments in bioengineering, synthetic morphology, artificial intelligence, biorobotics, and exobiology necessitate an expansion and generalization of this effort. Verbal reports (the Turing Test) and homology to human brains are utterly inadequate criteria for assessing the status of novel, unconventional agents that offer no familiar touchstone of phylogeny or anatomy. We must develop principled approaches to evaluating the sentience of (and thus, our responsibility to) beings of unfamiliar provenance and …
Does The Sentience Framework Imply All Animals Are Sentient?, Kristin Andrews
Does The Sentience Framework Imply All Animals Are Sentient?, Kristin Andrews
Animal Sentience
The eight criteria proposed in Crump et al.’s framework for evaluating pain sentience in decapod crustaceans are just the tip of the iceberg when it comes to markers that could increase confidence in an animal’s sentience more generally. Some of the commentaries have already pointed out that pain is only one kind of sentience (Souza Valente). It has also already been pointed out that there are other criteria for pain that could be usefully added to the framework’s eight (Burrell). This expansive thinking about criteria that can be used to increase confidence in sentience raisess the question: in an expansive …

Distinguishing Epistemic And Moral Grounds For Legal Protection, Carlos Montemayor
Animal Sentience
The criteria proposed by Crump et al. are based on various cognitive roles associated with sentience. A subset of them may be sufficient for certain kinds of welfare, but the presence of all of them should be considered as clearly sufficient for substantial kinds of legal protection based on their relation to capacities that we consider essential for moral standing in human beings.

Pitzer Faculty Publications and Research
Disciplines like evolutionary-developmental psychology admirably focus on trying to rehabilitate Narrow Evolutionary Psychology (NEP) from within, by adding a developmental focus to NEP’s tenets of adaptationism and computationalism. We argue, however, that these tenets are fundamentally incompatible with taking psychology and its development seriously, and that the kinds of modifications introduced by evolutionary-developmental psychologists do not go deep enough to qualitatively change the non-developmental outlook of NEP.

Pitzer Faculty Publications and Research
Which evolutionary theory can best benefit psychological theory, research, and application? The most well-known school of evolutionary psychology has a narrow conceptual perspective (a.k.a., “Narrow Evolutionary Psychology” or NEP). Proponents of NEP have long argued that their brand of evolutionary psychology represents a full-fledged scientific revolution, with Buss (2020) recently likening NEP’s scientific impact to that of a Copernican or Darwinian paradigm shift. However, NEP stands on two traditions that are now the subjects of serious debate and revision: the neo-Darwinian adaptationist framework within evolutionary biology, and the computationalist “mind-as-computer” framework within cognitive science. Although NEP calls itself revolutionary, the …
Sentience As Part Of Emotional Lives, Frans B. M. De Waal
Sentience As Part Of Emotional Lives, Frans B. M. De Waal
Animal Sentience
It is high time to explore the sentience of invertebrate animals, but this topic cannot be discussed without also exploring their emotional lives, including positive emotions. Sentience probably evolved to allow the regulation of emotions by endowing them with feelings.
Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md
Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md
Animal Sentience
Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they …

Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Animal Sentience
Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.
The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer
The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer
Publications and Research
Roksandic et al. (2022) proposed the new species name Homo bodoensis as a replacement name for Homo rhodesiensis Woodward, 1921, because they felt it was poorly and variably defined and was linked to sociopolitical baggage. However, the International Code of Zoological Nomenclature includes regulations on how and when such name changes are allowed, and Roksandic et al.'s arguments meet none of these requirements. It is not permitted to change a name solely because of variable (or erroneous) later use once it has been originally defined correctly, nor can a name be modified because it is offensive to one or more …
Time To Stop Pretending We Don’T Know Other Animals Are Sentient Beings, Marc Bekoff
Time To Stop Pretending We Don’T Know Other Animals Are Sentient Beings, Marc Bekoff
Animal Sentience
Rowan et al.’s target article is an outstanding review of some of the history of the science of sentience, but one would have liked to see a much stronger “call to action.” We don’t need any more data to know that many other animals are sentient beings whose lives must be protected from harm in a wide variety of contexts. It is not anti-science to want more action on behalf of other animals right now.
Sentience In Decapod Crustaceans: A General Framework And Review Of The Evidence, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Sentience In Decapod Crustaceans: A General Framework And Review Of The Evidence, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Animal Sentience
We outline a framework for evaluating scientific evidence of sentience, focusing on pain experience. It includes eight neural and cognitive-behavioural criteria, with confidence levels for each criterion reflecting the reliability and quality of the evidence. We outline the rationale for each criterion and apply our framework to a controversial sentience candidate: decapod crustaceans. We have either high or very high confidence that true crabs (infraorder Brachyura) satisfy five criteria, amounting to strong evidence of sentience. Moreover, we have high confidence that both anomuran crabs (infraorder Anomura) and astacid lobsters/crayfish (infraorder Astacidea) meet three criteria—substantial evidence of sentience. The case is, …

Of Course Crustaceans Are Sentient: But There's More To The Story, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
Animal Sentience
We are in basic agreement with Crump et al. that animal welfare, particularly with regard to the experience of pain, is a topic of importance. However, we come to the issue from a different perspective, one in which all species are sentient and can feel pain. The implications of this theory are discussed.
Defending Human Difference By Raising The Bar, Joe Gough
Defending Human Difference By Raising The Bar, Joe Gough
Animal Sentience
Chapman & Huffman (C&H) offer a theory of why we humans want to believe that we are different: to justify our cruelty to animals. This commentary offers further supporting evidence of this and examines more closely what the claim that humans are ‘different’ amounts to. It also considers some methodological issues in animal psychology closely related to C&H ‘s theory. These problems result from a common strategy for defending hypotheses about human difference.
Sentience Politics : A Fishy Perspective, Culum Brown
Sentience Politics : A Fishy Perspective, Culum Brown
Animal Sentience
The plight of fishes has almost certainly got worse since Bentham (1789) coined the phrase “The question is not Can they reason? nor, Can they talk? but Can they suffer?” Despite the fact that fishes are increasingly recognised as sentient animals worthy of protection under animal welfare legislation in many countries around the world, fishing practices are almost universally exempt activities. The human population continues to grow, and, surprisingly, per capita intake of fish is still increasing (FAO 2020). The source of this fish is not wild stocks (catches of which have remained more or less stagnant for …
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Animal Sentience
Rowan et al.’s target article provides a valuable indication of the work that was required to reach the point where animals are recognised as sentient in various laws. To ensure this work was not in vain, the language of sentience needs to be used as a moral currency to demand further cultural change involving greater human respect for animals.
All Living Organisms Are Sentient, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
All Living Organisms Are Sentient, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
Animal Sentience
We argue that all living organisms, from the simplest unicellular prokaryotes to Homo sapiens, have valenced experiences—feelings as states of preference—and are capable of cognitive representations. Bacteria can learn, form stable memories, and communicate, hence solve problems. Rowan et al.'s statement that "Subjective feelings are just that — subjective — and are available only to the animal (or human) experiencing them" is true but irrelevant. When we see a fish flopping about in the bottom of a boat we immediately recognize suffering without having a glimpse of the nature of piscine distress. Some controlled anthropomorphism can go a …
The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
Animal Sentience
Although linked historically by Rowan et al., the scientific study of animal sentience and political campaigns to improve animal welfare should be kept separate, for at least two reasons. First, the separation makes it clear that standards of evidence acceptable for ethical or political decisions on animal welfare can be lower than those required for a rigorously scientific approach to animal sentience. Second, it helps to avoid confirmatory bias in the form of giving undue weight to results that are in line with pre-conceived ideas and political views.
The Reality And Prevalence Of Animal Sentience, Antonio Damasio
The Reality And Prevalence Of Animal Sentience, Antonio Damasio
Animal Sentience
Rowan et al use findings from neurobiology, clinical neurology, and general biology to argue for the extensive presence of sentience in animals, but they are wisely cautious concerning when in the phylogenetic scale that emergence occurred.

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips
Animal Sentience
In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Symposium of Student Scholars
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …
Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M.

Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M. Alba, Stephen R. Frost, Dagmawit Abebe Getahun, Christopher C. Gilbert
Publications and Research
The purpose of this application, under Articles 23.9.3 and 81.1 of the Code, is to conserve the usage of the species-group name Simopithecus oswaldi Andrews, 1916 by giving it precedence over its senior subjective synonym Cynocephalus atlanticus Thomas, 1884. Theropithecus is a common to dominant member of the extinct primate community across Africa after 4 million years ago (Jablonski & Frost, 2010) and often co-occurred with extinct humans (Hominini); fossils are also known rarely across Eurasia (Roberts et al., 2014). Most fossil samples are currently included in Theropithecus oswaldi (Andrews, 1916), which is often divided into chrono-geographic subspecies. Cynocephalus atlanticus …
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter
Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter
Intuition: The BYU Undergraduate Journal of Psychology
Darwin offered an evolutionary perspective on the origins of human morality, suggesting that humans share a biological foundation with nonhuman primates. This paper reviews the current literature on moral and prosocial behaviors of nonhuman primates, specifically examining whether nonhuman primates exhibit behaviors that are typical of empathy and fairness. The literature documents that nonhuman primates exhibit empathetic behaviors regarding emotional contagion and sympathetic concern. There is also evidence that nonhuman primates have a sense of fairness, seen in their reciprocal behaviors and aversion to inequity. Taken together, this suggests that there are evolutionary roots of morality, lending empirical support to …
The Phoenix, Fernanda Perez-Alvarez
The Phoenix, Fernanda Perez-Alvarez
Montserrat Annual Writing Prize
This article uses a mythical creature, the phoenix, to examine and illustrate the biological principles for generation of an adult body plan from a single cell. Using the study of developmental biology, it explores the cellular and molecular biology that underpins the massive complexity of creating an adult body plan. It also explores the similarities and differences between different embryos, and how nature and evolution have shaped the biology of those embryos to create different body plans.
Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad
Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad
Jeffrey Stevens Publications
Teaching owners how to train their dogs is an important part of maintaining the health and safety of dogs and people. Yet we do not know what behavioral characteristics of dogs and their owners are relevant to dog training or if owner cognitive abilities play a role in training success. The aim of this study is to determine which characteristics of both dogs and owners predict success in completing the American Kennel Club Canine Good Citizen training program. Before the first session of a dog training course, owners completed surveys evaluating the behavior and cognition of their dog and themselves. …

Are Capuchin Monkeys (Sapajus Spp.) Sensitive To Lost Opportunities? The Role Of Opportunity Costs In Intertemporal Choice, Elsa Addessi, Valeria Tierno, Valentina Focaroli, Federica Rossi, Serena Gastaldi, Francesca De Petrillo, Fabio Paglieri, Jeffrey R. Stevens
Jeffrey Stevens Publications
Principles of economics predict that the costs associated with obtaining rewards can influence choice. When individuals face choices between a smaller, immediate option and a larger, later option, they often experience opportunity costs associated with waiting for delayed rewards because they must forego the opportunity to make other choices. We evaluated how reducing opportunity costs affects delay tolerance in capuchin monkeys. After choosing the larger option, in the High cost condition, subjects had to wait for the delay to expire, whereas in the Low cost different and Low cost same conditions, they could perform a new choice during the delay. …
Social Comparison Tendencies And The Reward Value Of Same-Sex Beauty Among Heterosexual Women, Melissa M. Martin Ms.
Social Comparison Tendencies And The Reward Value Of Same-Sex Beauty Among Heterosexual Women, Melissa M. Martin Ms.
Cal Poly Humboldt theses and projects
Previous studies have suggested that heterosexual women, but not heterosexual men, find same sex beauty rewarding. This finding has been attributed to a “greater bisexual interest among heterosexual women”, but no other explanations have been offered or tested. The current study aimed to explore social comparison tendencies as a potential alternate explanation to this previously observed finding. Twenty-three heterosexual women completed a series of questionnaires designed to assess their social comparison tendencies (the social comparison orientation scale, the physical appearance comparison scale, and the intrasexual competition scale). They also completed a “pay-per-view” keypress task to measure the reward value of …

Alfred Russel Wallace Notes 15. Wallace's Many "Hats": What Should We Call Him?, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) has been referred to by name through the aid of a variety of labels – some thirty or more, in fact – that link him to his emphases of attention. How many of these labels are/were justifiable? The assessment here is that he is probably best remembered as a ‘naturalist,’ ‘geographer,’ ‘evolutionist,’ and ‘social critic.’

African Land Mammal Ages, John Van Couvering, Eric Delson
African Land Mammal Ages, John Van Couvering, Eric Delson
Publications and Research
We define 17 African land mammal ages, or AFLMAs, covering the Cenozoic record of the Afro-arabian continent, the planet’s second largest land mass. While fossiliferous deposits are absent on the eroded plateau of the continent’s interior, almost 800 fossil genera from over 350 locations have now been identified in coastal deposits, karst caves, and in the Neogene rift valleys. Given a well-developed geochronologic framework, together with continuing revision to the fossil record—both stimulated by the story of human evolution in Africa—and also to compensate for the variation in fossil ecosystems across such great distances, the AFLMAs are biochronological units defined …
Alfred Russel Wallace Notes 13: Wallace On Prayer, Charles H. Smith
Alfred Russel Wallace Notes 13: Wallace On Prayer, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) is known to most for his natural history explorations and theoretical biology, but he also developed thoughts on a number of subjects relatable to a wider appreciation of evolutionary cosmology. His adoption of spiritualism, for one, was attuned to this mission, and in turn his otherwise difficult-to-interpret two-sided position on prayer.
