Griffin's Slow Burn Revolution In Philosophy And Comparative Cognition, Kristin Andrews
Griffin's Slow Burn Revolution In Philosophy And Comparative Cognition, Kristin Andrews
Animal Sentience
Ristau presents Griffin as launching a scientific revolution supported by philosophical insights. This commentary focuses on two points: Griffin as a scientific revolutionary, although the cognitive ethology revolution is not yet complete; and on the immense influence Griffin had, and continues to have, on philosophy.
What Is It Like To Be A Diplomat? Reflections On Donald Griffin And Emotion, Oliver H. Turnbull
What Is It Like To Be A Diplomat? Reflections On Donald Griffin And Emotion, Oliver H. Turnbull
Animal Sentience
This commentary addresses three aspects of Donald Griffin’s work: (1) his thoughts beyond cognition, on emotion; (2) his views on the earliest origins of mind, including primitive forms of consciousness; and (3) his diplomatic use of memorable phrases to facilitate change.

What Is It Like To Be A Cognitive Ethologist?, Anne Wordsworth She/Her
Animal Sentience
Donald Griffin not only made the study of animal minds acceptable for scientific investigation but the work of the cognitive ethologists that he inspired made animals and their lives fascinating and accessible to the greater public. The scrupulously detailed examination of his life and work by Ristau ensures that this history will always be there to respect his work and his legacy

Can Animal Consciousness Be Resolved Scientifically?, Yoram Gutfreund
Animal Sentience
Carolyn Ristau's biography of Donald Griffin is a comprehensive work that sheds light on a seminal chapter in the history of ethology—the ambitious attempt to establish a research field dedicated to animal consciousness. Although Donald Griffin's endeavor ultimately fell short of its revolutionary goals, it catalyzed significant progress in understanding evolution and mechanisms of animal cognition.
Beyond Human Perception: The Remarkable Science Of Donald R. Griffin, Gareth Jones
Beyond Human Perception: The Remarkable Science Of Donald R. Griffin, Gareth Jones
Animal Sentience
Carolyn Ristau shows how Donald Griffin’s revolutionary science sometimes progressed from ridicule, to opposition, to being self-evident. Griffin’s work involved phenomena beyond human perception, making it sometimes difficult for others to fathom. His work on ultrasonic echolocation, navigation and animal cognition has shifted established paradigms. His ‘zoomorphic’ approach provides a realistic framework for understanding how other animals perceive the world.

Donald Griffin: A Visionary In Science And Consciousness, Brock Fenton
Animal Sentience
I share some reflections on a sabbatical with Donald Griffin a half-century ago, with fieldwork on bats and echolocating swiftlets in Australia and our discussions of animal behavior and consciousness. Griffin's influence has been vast, from recent advances in bat research, including learning, navigation, and longevity, to his enduring legacy as a pioneer in animal cognition.
Cognitive Ethology, Animals And Society, And The American Sociological Association, Arnold Arluke
Cognitive Ethology, Animals And Society, And The American Sociological Association, Arnold Arluke
Animal Sentience
Griffin’s The Question of Animal Awareness (1976) and Animal Minds (2001) enabled and emboldened other disciplines to expand their research to include non-human animals. The creation of a dedicated section on human-animal relationships in sociology’s national professional organization is but one example.
Objective Bat Phenomenology, Thomas Nagel
Objective Bat Phenomenology, Thomas Nagel
Animal Sentience
Our discussions prompted Donald Griffin to campaign for the recognition of animal consciousness as a subject for scientific investigation. Ristau shows how much has since been discovered about the experiences of bats and other creatures, by Griffin and others, in spite of the limits to full knowledge imposed by our biological differences. But Ristau seriously misrepresents me as holding that we can know nothing about what it is like to be a bat, whereas these results are precisely of the kind I envisioned in proposing an “objective phenomenology.”
To Be Conscious Or Not To Be, Bjørn Grinde
To Be Conscious Or Not To Be, Bjørn Grinde
Animal Sentience
Carolyn Ristau has done a fine job summarizing the work and life of the zoologist Donald Griffin. Most scientists now accept the existence of animal sentience, but identifying which species possess consciousness remains controversial. Griffin defined consciousness as "the subjective state of feeling or thinking about objects and events.” Nonconscious processes are faster and more energy-efficient, however, and often drive behavior. Consciousness probably evolved for complex decision-making, shaped by evolutionary continuity, with feelings as a common currency for evaluating outcomes. Its survival advantage may be limited, and its presence across species varies depending on evolutionary trajectories.
Communication In Noise Is The Window On Cognition, R. Haven Wiley
Communication In Noise Is The Window On Cognition, R. Haven Wiley
Animal Sentience
As Griffin surmised, communication is the window on cognition, but as shown here, only if it is noisy. This commentary is an invitation to consider the full implications of the evolution of noisy communication. A combination of Information Theory, Signal Detection Theory, and Natural Selection, in a unified theory of the evolution of communication, reveals that noise is inevitable. All organisms are thus decision makers. Perception, thought, freedom of decision, self-awareness, metabolism, and natural selection all share the consequences of signals in noise. A full understanding of each requires attention to the errors of receivers. Griffin’s hunch is correct with …
Attempting To Answer The Question Of Animal Awareness, Alexandra Horowitz
Attempting To Answer The Question Of Animal Awareness, Alexandra Horowitz
Animal Sentience
It was as a graduate student that I first encountered the work of both Donald Griffin and Carolyn Ristau. Griffin's The Question of Animal Awareness (1976) and Animal Minds (2001) helped a budding animal-minds researcher appreciate both the possibilities of studying non-human animal consciousness and the struggle that such an undertaking would face. Now Ristau's (2024a,b) timely biography helps explain how Griffin became the figure in animal cognition that he is.
Donald Griffin, Sentience, And Animal Research Ethics, John Gluck
Donald Griffin, Sentience, And Animal Research Ethics, John Gluck

Recollection of early encounters with Donald Griffin’s pioneering work on animal awareness, provoking intense, often hostile academic responses, later forgotten.
Can We Use Judgement Bias To Assess The Welfare Of Fish In Aquariums And Zoos?, Culum Brown
Can We Use Judgement Bias To Assess The Welfare Of Fish In Aquariums And Zoos?, Culum Brown
Animal Sentience
This commentary examines the potential of tests of judgment bias to assess fish welfare in aquariums and zoos. Judgment bias offers a non-invasive approach to interpreting affective states in animals, using cognitive responses to ambiguous stimuli as indicators of mental wellbeing. Despite the constraints of captive environments—such as limited handling and species diversity in exhibits—recent adaptations of judgment-bias protocols make them suitable across taxa, including fishes. Collaborations with progressive zoos and aquariums could facilitate this research, based on the shared goal of enhancing animal welfare and promoting public education.
Précis Of: "Birds, Bats And Minds: Tales Of A Revolutionary Scientist, Donald R. Griffin", Carolyn A. Ristau
Précis Of: "Birds, Bats And Minds: Tales Of A Revolutionary Scientist, Donald R. Griffin", Carolyn A. Ristau
Animal Sentience
Donald Griffin co-discovered bat sonar and founded the field of echolocation. He studied bird migration and founded Cognitive Ethology, the study of animal awareness and mental experiences. In all these endeavors, he faced hostile opposition. The biography (Ristau 2024) examines Griffin's life and the scientific explorations by him and others in these fields. This Précis emphasizes his arguments and supporting evidence for animal consciousness as well as his later research. Griffin considered the inhibiting assumptions made by scientists, including Cartesian views, the misunderstanding of innate behaviors, prejudice against lower animals, concern with violations of parsimony, and the assertions of the …
Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano
Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano
Animal Sentience
Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …
Norms And Variance Fail To Predict Butterfly Effects On Social Dynamics By Idiosyncratic Individuals, Stephen F. Stringham, Lynn Rogers, Ann Bryant
Norms And Variance Fail To Predict Butterfly Effects On Social Dynamics By Idiosyncratic Individuals, Stephen F. Stringham, Lynn Rogers, Ann Bryant
Animal Sentience
Adaptations and adjustments to current environmental conditions are manifest in behavioral norms. Knowing norms facilitates population-level prediction, but doesn’t predict individual behavior where idiosyncrasies might trigger “butterfly effects." Knowledge of individual quirks is particularly important for risk assessment and management during close encounters between humans and potentially lethal wildlife, including bears (Ursus spp.). Innovative foraging techniques can alter population vigor and viability. Traits at the tails of a bell curve might hold the greatest potential for adapting to environmental change.
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff
Animal Sentience
Individual differences in personality types within the same species have been studied much less than differences between species and populations. Personality differences are related to risk-taking and exploration, which in turn correlate with individuals' daily responses, decisions, and fitness. Bold and shy personality types can have different advantages and disadvantages under different social or environmental pressures. Analyzing personality differences has helped clarify how elk habituate to a well-populated area and how management strategies can be adapted to them. For wolves newly repatriated to Colorado, individual personality factors are likely to prove important for adapting to their new homes as well …

Precommentary: Animal Personality Needs Animal Sentience, Ralph Adolphs, Yue Xu
Animal Sentience
We are grateful to Owens, Bryja & Bekoff (2024) for their important discussion of individual differences in animals, emphasizing the role of personality in conservation, wildlife research, and wellbeing. But their emphasis also raises new challenges: How should we conceive of personality in nonhuman species? what modern tools could be leveraged to best measure it? and, perhaps most important of all: how can we ensure that the conscious experience of animals — their capacity for wellbeing and for suffering — is not forgotten along the way? We touch on each of these challenges in this invited Precommentary in the hope …
Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.
Not Just Bony Fish: All Nonmammalian And Nonavian Animals Are Neglected In Both Welfare And General Research, Jennifer A. Mather Ph.D.
Animal Sentience
The lack of research on fish welfare highlighted by Oldfield & Bonano (2024) is only part of a more general problem: a relative neglect of animals other than mammals and birds. The causes are our lack of knowledge, our negative view of what we consider to be “lower” animals and our underestimation of their intelligence and sensitivity. Our estimation will increase as our knowledge increases. As a broader view spreads to the public through the media, it should gradually increase the demand to expand both research and welfare, especially beyond mammals and birds.
Animal Personality And Sentience As Distinct Concepts, Mark Briffa
Animal Personality And Sentience As Distinct Concepts, Mark Briffa
Animal Sentience
Owens et al (2024) discuss how knowledge of both animal personality and sentience in target populations can be leveraged to enhance wildlife conservation programmes. In this commentary I expand on the distinction between these two concepts. Behavioural differences should be considered broadly across conservation programmes, not just those involving species deemed sentient.

Donald Griffin: A Visionary In Science And Consciousness, Charles Foster
Animal Sentience
Carolyn Ristau’s (2024) timely biography reviews Donald Griffin’s pioneering ideas with depth and historical perspective, describing Griffin’s approach to science, his openness to interdisciplinary insights, and his bold stance on consciousness. Ristau’s work highlights Griffin’s relevance to contemporary debates on consciousness and natural selection.
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Don Griffin And The Early Days Of Cognitive Ethology, Gordon M. Burghardt
Animal Sentience
Carolyn Ristau’s trilogy provides a comprehensive account of Donald Griffin’s life and work, with the third volume focusing on cognitive ethology. This commentary focuses primarily on my own interactions with Don, particularly during my sabbatical at Rockefeller University when his campaign for cognitive ethology was gaining momentum. I recount my research on reptile behavior and cognition, my collaboration with Don and others at RU, and my role in advancing his ideas while contextualizing them within 19th-century comparative psychology. I also discuss developments in cognitive ethology, including critical anthropomorphism, the challenges of integrating subjective experience into behavioral science, and Griffin’s lasting …

Other Perspectives On Animals, Their Sentience And Cognition, Joyce M. D'Silva Mrs
Animal Sentience
For those of us who work to achieve legal recognition that animals are sentient beings, and should in many cases be allotted personhood, Donald Griffin is indeed an inspiration and a true game-changer. He put paid to the narrow behaviourist interpretation of animals’ lives promoted by Skinner et al. He became a real heir to Darwin’s belief in animal emotions. He enabled campaigners for animal welfare and indeed animal rights to quote his work as a distinguished scientist to give gravitas to their calls for legal recognition and protection of animals.
An Individuals-Oriented Approach To Conservation, Kristy M. Ferraro
An Individuals-Oriented Approach To Conservation, Kristy M. Ferraro
Animal Sentience
Individual cognitive and emotional differences in personality among animals, along with differences in their behavioral traits, are increasingly important in conservation efforts. It is not only more effective but more ethical to take both collective and individual perspectives into account in both research and practice.
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Wildlife Conservation And Adaptation To Humans, Valeria Mazza Phd, Claudio Carere
Animal Sentience
For many animal species, the ability to adapt to coexistence with the human species and to the environmental changes that humans cause is a biological imperative. This adaptive capacity varies not only between species, but within species. Studying individual differences in animals’ behavioral, cognitive and physiological adaptability is important for integrating ethology and conservation. Findings about animal cognitive capacities, including learning, need to be applied in conservation—but humans need to be educated about ethology, coexistence and conservation too.
Multiple Ways To Implement And Infer Sentience, Nicolas Rouleau, Michael Levin
Multiple Ways To Implement And Infer Sentience, Nicolas Rouleau, Michael Levin
Animal Sentience
Segundo-Ortin & Calvo’s (S&C’s) thorough review of “plant neurobiology” presents evidence supporting the possibility of plant sentience. They make a compelling case that plants anticipate, assess risk, cooperate, mimic, and pursue goals, as do their animal counterparts. S&C point out that there is a double standard: behavioural patterns associated with subjective experiences in humans are considered valid for inferring cognition in non-human animals but not in diverse other systems including plants. We argue that cognitive functions, including sentience, can potentially be achieved by very different systems and their disparate substrates. We offer some context from the basal cognition literature and …

Plant Sentience: Not Now, Maybe Later?, Helen Tiffin
Animal Sentience
Segundo-Ortin’s target article provides compelling evidence for physiological and behavioral complexity in plants, bringing us closer to a recognition of some kind of plant cognition – but it does not as yet offer firm grounds for inferring sentience (feeling) in plants, The recent history of the scientific demonstration and recognition of animalsentience in invertebrates, for example, does not entirely rule out the possibility that further research might provide support for plant sentience. Should this ever turn out to be the case, the ethical problems raised are not insurmountable, and would not threaten the now proven case for animal sentience

Crazier Hypotheses: Panpsychism, José E. Burgos, Giselle M. Castañeda
Animal Sentience
Abstract: Segundo-Ortin & Calvo (S&C) invite readers to consider seriously the hypothesis that plants have phenomenal consciousness or sentience. Their case is based on behavioral evidence to support their hypothesis. While the hypothesis seems crazy to many, there is a crazier hypothesis – panpsychism – according to which everything is sentient. We discuss panpsychism to raise a number of philosophical questions about S&C’s hypothesis.
Limits To Sentience, Donald M. Broom
Limits To Sentience, Donald M. Broom
Animal Sentience
There are many parallels between cellular function in animals and plants. Plants can have complex interactions with their environments. But they lack a central nervous system, which is a prerequisite for sentience (the capacity to feel). In my view the suggestion that plants are sentient is not only empirically incorrect but potentially harmful to the efforts to protect the welfare of sentient beings.
Plant Sentience: Time Scale Matters, Alessio Plebe
Plant Sentience: Time Scale Matters, Alessio Plebe
Animal Sentience
Segundo-Ortin & Calvo (2023) have made a valuable effort in directing the discussion about plant sentience toward a strict scientific path. However, scientific endeavors must reconcile with common sense beliefs. Although nowadays people tend to accept the idea of animal sentience, this is not easily extended to plants. One reason is the difference in time scale in which phenomena occur in plants and animals; but this still does not preclude the possibility , in principle, of plant sentience in a form difficult for us to imagine.
