Are Insects Sentient?, Michael Tye Aug 2016

Are Insects Sentient?, Michael Tye

Animal Sentience

I comment on the methodology used by Klein & Barron for dealing with the question of insect sentience and I briefly make a proposal of my own. Once it is granted that insects are sentient, a further question arises: which insects are subject to which states of sentience? Do insects feel pain, for example? If so, which ones? On the further question, I note, Klein & Barron have nothing to say.

Animal Grieving And Human Mourning, Matteo Colombo Aug 2016

Animal Grieving And Human Mourning, Matteo Colombo

Animal Sentience

King’s How animals grieve beautifully describes several ways in which animals and humans show a similar capacity for grief. Yet this book does not sufficiently emphasise the language-empowered capacity to objectify thinking and sentiments about death, which makes human mourning unique. Here I put this capacity into focus and relate it to the social-normative aspect of human mourning that seems to be missing in other animals.

Insects Join The Consciousness Fray, Bjorn H. Merker Aug 2016

Insects Join The Consciousness Fray, Bjorn H. Merker

Animal Sentience

Klein & Barron's review of recent insect neurobiology helps correct the impression that insect behavior is orchestrated without the benefit of central integrative mechanisms. Given their existence, the authors go on to ask whether these central mechanisms also feature the kind of integrative operations that support sentience, and propose that they do. Along the way they raise a number of conceptual and evidentiary issues of fundamental importance for the neuroscience of consciousness, allowing me to comment favorably on a number of them. I conclude by pointing to ways in which the conception of insect sentience they outline might be tested …

Insects Have Agency But Probably Not Sentience Because They Lack Social Bonding, J. H. Van Hateren Aug 2016

Insects Have Agency But Probably Not Sentience Because They Lack Social Bonding, J. H. Van Hateren

Animal Sentience

Klein & Barron (2016) argue that insects have sentience because of functional similarities between the insect brain and vertebrate midbrain. Based on a recent theory of agency and consciousness, I argue that the functional similarities merely point to an advanced form of agency. Insects presumably lack the capacity for social bonding that may be required for subjective experiencing.

Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere Jul 2016

Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere

Animal Sentience

Insects might have been the first invertebrates to evolve sentience, but cephalopods were the first invertebrates to gain scientific recognition for it.

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber Jul 2016

Caterpillars, Consciousness And The Origins Of Mind, Arthur S. Reber

Animal Sentience

A novel framework for the origins of consciousness and mind, the Cellular Basis of Consciousness (CBC), is presented. The model is based on a simple, perhaps radical axiom: subjectivity is an inherent feature of particular kinds of organic form. Experiential states, including those denoted as "mind" and "consciousness," are present in the most primitive species. The model has several conceptual and empirical virtues, among them: (a) it (re)solves the problem of how minds are created by brains ─ also known as the "Hard Problem" (Chalmers 1995) ─ by revealing that the apparent difficulty results from a category error, (b) it …

Why Animals Are Persons, Tony Cheng Jul 2016

Why Animals Are Persons, Tony Cheng

Animal Sentience

Rowlands’s case for attributing personhood to lower animals is ultimately convincing, but along the way he fails to highlight several distinctions that are crucial for his argument: Personhood vs. personal identity; the first person vs. its mental episodes; and pre-reflective awareness in general vs. one specific case of it.

Are Animals Persons?, Mark Rowlands Jul 2016

Are Animals Persons?, Mark Rowlands

Animal Sentience

It is orthodox to suppose that very few, if any, nonhuman animals are persons. The category “person” is restricted to self-aware creatures: humans (above a certain age) and possibly some of the great apes and cetaceans. I argue that this orthodoxy should be rejected, because it rests on a mistaken conception of the kind of self-awareness relevant to personhood. Replacing this with a sense of self-awareness that is relevant requires us to accept that personhood is much more widely distributed through the animal kingdom.

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron Jul 2016

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron

Animal Sentience

To what degree are non-human animals conscious? We propose that the most meaningful way to approach this question is from the perspective of functional neurobiology. Here we focus on subjective experience, which is a basic awareness of the world without further reflection on that awareness. This is considered the most basic form of consciousness. Tellingly, this capacity is supported by the integrated midbrain and basal ganglia structures, which are among the oldest and most highly conserved brain systems in vertebrates. A reasonable inference is that the capacity for subjective experience is both widespread and evolutionarily old within the vertebrate lineage. …

Cross-Species Mind-Reading, Stevan Harnad Jul 2016

Cross-Species Mind-Reading, Stevan Harnad

Animal Sentience

We can never be sure anyone else is sentient. But we can be sure enough in the case of other people, nonhuman primates, mammals, birds, fish, lower vertebrates and invertebrates as to make scepticism academic and otiose (not to mention monumentally cruel). The only genuinely uncertain kinds of cases are jellyfish, microbes and plants. The rest is not about whether but what they are feeling.

My Orgasms Cannot Be Traded Off Against Others’ Agony, Stevan Harnad Jul 2016

My Orgasms Cannot Be Traded Off Against Others’ Agony, Stevan Harnad

Animal Sentience

Only I can calculate my own welfare as net pleasure minus pain. No one else can do that calculation for me – nor for a population, and especially not averaging across some individuals’ pleasure and other individuals’ pain. Pain and pleasure are incommensurable and only pain matters morally. To maximize welfare is to minimize pain.

In Praise Of Fishes: Précis Of What A Fish Knows (Balcombe 2016), Jonathan Balcombe Jul 2016

In Praise Of Fishes: Précis Of What A Fish Knows (Balcombe 2016), Jonathan Balcombe

Animal Sentience

Our relationship to fishes in the modern era is deeply problematic. We kill and consume more of them than any other group of vertebrates. At the same time, advances in our knowledge of fishes and their capabilities are gaining speed. Fish species diversity exceeds that of all other vertebrates combined, with a wide range of sensory adaptations, some of them (e.g., geomagnetism, water pressure and movement detection, and communication via electricity) alien to our own sensory experience. The evidence for pain in fishes (despite persistent detractors) is strongly supported by anatomical, physiological and behavioral studies. It is likely that fishes …

Sentience As Moral Consideration And Disvalue In Nature, Daniel Dorado Jul 2016

Sentience As Moral Consideration And Disvalue In Nature, Daniel Dorado

Animal Sentience

In recent work Ng assumes that it is good to engage in activities aimed at promoting ecosystem conservation. The only way Ng can derive this from the axiology he assumes (the view that wellbeing is the only intrinsically valuable or disvaluable thing) would be to assume that ecosystem conservation would benefit the individuals involved. This can be so as long as value prevails over disvalue in the target environments. Ng seems to assume this is indeed the case, but he does not explain why, and it is a claim that goes against the conclusions he has argued for previously (Ng …

Changing Attitudes Towards Animals In The Wild And Speciesism, Oscar Horta Jul 2016

Changing Attitudes Towards Animals In The Wild And Speciesism, Oscar Horta

Animal Sentience

I argue that despite Ng’s claim that we should postpone the defense of those animals that live in the wild, we do have reasons to start spreading concern for them now. We can do it by (i) changing public attitude by heightening awareness of speciesism, by which we will also challenge animal exploitation; and (ii) by disseminating information about the situation of animals in the wild.

On The Screen, In The Mind: An Erp Investigation Into The Interaction Between Visuo-Spatial Information And Spatial Language During On-Line Processing, Emily Zane Jun 2016

On The Screen, In The Mind: An Erp Investigation Into The Interaction Between Visuo-Spatial Information And Spatial Language During On-Line Processing, Emily Zane

Dissertations, Theses, and Capstone Projects

This project used Event-Related Potentials (ERPs) to explore neurophysiological brain responses to prepositional phrases involving concrete and abstract reference nouns (e.g., "plate" and "moment", respectively) after the presentation of objects with varying spatial features. Prepositional phrases were headed by in or on and were either matching (e.g., "in the plate/moment") or mismatching (e.g., "on the plate/moment"). Conjunction phrase matches and fillers were also presented. Before half of the concrete-phrase items, a photographic depiction of the reference noun was presented. In these photographs, objects were displayed in a way that was either more appropriate for in or for on. Similarly, before …

Virtual V1sion: A Collaborative Coding Project, Cheryl Olman May 2016

Virtual V1sion: A Collaborative Coding Project, Cheryl Olman

MODVIS Workshop

Virtual V1sion is a new idea for fostering modeling collaborations and data sharing. While still in its infancy, the ultimate goal is a website that hosts repositories for (1) interchangeable model elements, (2) datasets that can be fit/predicted by those models, and (3) educational modules that explain the background for both the models and the datasets. The scope of the modeling is limited to predictions of V1 responses, although not all computations represented by model elements in Virtual V1sion are required to be V1-intrinsic: a goal of the project is to provide a framework in which predictions for modulation by …

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd May 2016

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker May 2016

Learning Object Representations For Modeling Attention In Real World Scenes, Alex Schwarz, Frederik Beuth, Fred H. Hamker

MODVIS Workshop

Models of visual attention have been rarely used in real world tasks as they have been typically developed for psychophysical setups using simple stimuli. Thus, the question remains how objects must be represented to allow such models an operation in real world scenarios. We have previously presented an attention model capable of operating on real-world scenes (Beuth, F., and Hamker, F. H. 2015, NCNC, which is a successor of Hamker, F. H., 2005, Cerebral Cortex), and show here how its object representations have been learned. We have used a learning rule based on temporal continuity (Földiák, P., 1991, Neural Computation) …

Building Object Representations: Mechanisms Of Perceptual Learning In Human Visual Cortex, Stephanie M. Long May 2016

Building Object Representations: Mechanisms Of Perceptual Learning In Human Visual Cortex, Stephanie M. Long

Psychological Science Undergraduate Honors Theses

Extensive literature in the cognitive neurosciences has been dedicated to understanding the neural processes involved in object category learning. However, much remains to be learned regarding the mechanisms by which high-level visual patterns are extracted from a crowded visual scene, segregated into discrete object categories, and represented in the cortical visual hierarchy. Here, we used event-related potentials (ERPs) to investigate the neural underpinnings of visual object category extraction in a cluttered visual environment. Electroencephalography (EEG) was continuously recorded while subjects were given a hybrid of an object category learning and visual search task. In this hybrid task, a peripheral array …

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams Apr 2016

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams

Senior Honors Theses

Alan Turing asked if machines can think, but intelligence is more than logic and reason. I ask if a machine can feel pain or joy, have visions and dreams, or paint a masterpiece. The human brain sets the bar high, and despite our progress, artificial intelligence has a long way to go. Studying neurology from a software engineer’s perspective reveals numerous uncanny similarities between the functionality of the brain and that of a computer. If the brain is a biological computer, then it is the embodiment of artificial intelligence beyond anything we have yet achieved, and its architecture is advanced …

The Line Drawn On Pain Still Holds, Bjorn H. Merker Mar 2016

The Line Drawn On Pain Still Holds, Bjorn H. Merker

Animal Sentience

The many substantive criticisms raised against Key by me and by many of the other commentators will not disappear by ignoring or waving them aside with meta-discourse about anthropomorphism, just-so stories, or celestial teapots. The conceptual edifice Key inhabits and defends with such gusto may look like an impregnable fortress from the inside – and Key behaves as if it were. From the outside, however, it looks more like a ramshackle structure gaping with holes and pieced together from imperfectly understood neuroscience and often faulty literature citations.

Slavery, Welfare And The Sixth Extinction, Stephen R. Clark Mar 2016

Slavery, Welfare And The Sixth Extinction, Stephen R. Clark

Animal Sentience

Ng’s laudable concern for animal welfare would be welcome to any sensible slave-owner wishing to preserve his investment. What welfarism – for slave-owners and animal husbandmen – fails to call into question is whether we have the right to breed, hold captive and kill animals at all: If it matters, as the widely recognized slogan of ‘Five Freedoms’ suggests, that animals have the chance to live a ‘normal’ life, then more matters than keeping them ‘happy’ in subjection. Their lives – and also the lives of wild things – also deserve respect.

The Pribram – Bohm Hypothesis, Shelli R. Joye Mar 2016

The Pribram – Bohm Hypothesis, Shelli R. Joye

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

A holoflux theory of consciousness as modulated energy is hypothesized and shown to support both local and non-local properties. This thesis emerges from an integral evaluation of evidence drawn from: (1) the holonomic mind/brain theories of Karl Pribram, (2) the ontological interpretation of quantum theory by David Bohm. Applying an integral methodology to superimpose and correlate seemingly disparate concepts from among these sources and others, a composite-theory emerges, a “holoflux” theory of consciousness, after the term favored by Karl Pribram to describe David Bohm’s “holomovement” between an explicate order andan implicate order. This Pribram–Bohm composite holoflux theory is shown to …

Presence And The Paradox Of Love, Joanne Burtch

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

Spiritual experiences often seem unrelated to the intellectual orientation of science. However, some discussion of the laboratory study of spiritual practice does attempt to include the mystery and the human experience in its dialogue. An exploration of the paradox of love demonstrates how it might be possible to find a relationship between the scientific understanding of spirituality and the profundity of spiritual experience.

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

By sharing Professor Taylor’s impact on me with you in this way, I hope to offer a glimpse of the depth he pointed us to. Rather than just tell you his stories and his theories, I am sharing layers of my own experience both in similar synchronicities from my own personal mythology and also the meaning I make for myself as I go deeper in understanding what he was really teaching. If you can see that I am sharing something beyond the words themselves, then you know what he meant by soteriological writing. The words are used to help you …

Beyond Perennialist And Participatory Spiritualities: Transformation And Culture, Joanne Burtch Mar 2016

Beyond Perennialist And Participatory Spiritualities: Transformation And Culture, Joanne Burtch

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

A comparison of perennialism, participatory spirituality, and Gebser’s structures of consciousness demonstrates how deeper inquiry is required to understand how perennialism and participatory spirituality would address the relationship between individuals and culture with regard to how transformation happens. By reviewing how each of these philosophies approach context, the interpersonal, transformation, cultural relativity, pluralism, and multiplicity, the article identifies ambiguities that offer perennialism and participatory spirituality scholars the opportunity to explore their suppositions about spirituality more deeply.

Reembodying, Human Consciousness In The Earth, John Briggs Mar 2016

Reembodying, Human Consciousness In The Earth, John Briggs

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

For the last 20,000 years or so the dominant mode of human consciousness has been one that divides reality into subjects and objects, and focuses on human desires and needs. This anthropocentric mode of consciousness has invented religions, built civilizations, amassed knowledge, and developed technology and science. It has also disembodied us from the Earth and led to the Anthropocene Era. Still with us is another mode of human consciousness that arguably once existed in a balance with the anthropocentric mode during our long hunter-gatherer, Paleolithic sojourn. This holistic, integrative mode of consciousness experiences the Earth as a mother, and …
