Insect Consciousness: Fine-Tuning The Hypothesis, Jon Mallatt, Todd E. Feinberg 2016 Washington State University

Insect Consciousness: Fine-Tuning The Hypothesis, Jon Mallatt, Todd E. Feinberg

Animal Sentience

Although we are mostly supportive, we point out the strengths and weaknesses of Klein & Barron’s (2016) hypothesis that insects have the most basic form of consciousness. The strengths are in their application of Bjorn Merker’s vertebrate-derived ideas to arthropods, using their deep knowledge of insect brains. The weaknesses involve the controversial aspects of some of Merker’s ideas. We describe how the latter can be modified to strengthen the authors’ case for insect consciousness.


Feel Or Perspective?, Mark Rowlands 2016 University of Miami

Feel Or Perspective?, Mark Rowlands

Animal Sentience

The title of Klein & Barron’s well-argued and thought-provoking target article is, “Insects have the capacity for subjective experience.” However, they also frame their claim using the term “consciousness,” which they seem to take as equivalent to “subjective experience.” This assumed equivalence, I shall argue, is problematic in a way that might vitiate their central argument.


Universal Modes Of Awareness? A “Pre-Reflective” Premise, Uta M. Jürgens 2016 Swiss Federal Institute of Technology, Zürich & Swiss Federal Institute for Forest, Snow, and Landscape Research, Birmensdorf

Universal Modes Of Awareness? A “Pre-Reflective” Premise, Uta M. Jürgens

Animal Sentience

Mark Rowlands holds that creatures endowed with pre-reflective awareness may qualify as persons: In pre-reflective awareness, the self and the unity of mental life are implicit in the stream of experience. Rowlands generalizes from an introspective analysis of pre-reflective consciousness in humans to pre-reflective awareness in general. I describe three examples of empirical findings that corroborate the assumption that animal minds have some of the same basic modes of pre-reflective awareness as human minds.

What If Klein & Barron Are Right About Insect Sentience?, Bob Fischer 2016 Texas State University

What If Klein & Barron Are Right About Insect Sentience?, Bob Fischer

Animal Sentience

If Klein & Barron are right, then insects may well be able to feel pain. If they can, then the standard approach to animal ethics generates some implausible results. Philosophers need to develop alternatives to this framework to avoid them.


Subjective Experience And Moral Standing, Andy Lamey 2016 University of California, San Diego

Subjective Experience And Moral Standing, Andy Lamey

Animal Sentience

Klein & Barron’s analysis focuses on the capacity for any subjective experience at all. It does not seek to demonstrate that insects can experience pleasure and pain in particular. This would be something of which insects have not traditionally been thought capable. If further research were to demonstrate that one or more insect species turn out to be conscious, yet incapable of experiencing pleasure and pain, it would give rise to a philosophical question that ethicists have yet to answer: Would a creature that is conscious, but lacks the capacity to feel pain, have moral standing?


Phylogenetic Relationships And Evolution Of Snakes, Alex Figueroa 2016 University of New Orleans, New Orleans

Phylogenetic Relationships And Evolution Of Snakes, Alex Figueroa

LSU New Orleans Theses and Dissertations

Snakes represent an impressive evolutionary radiation of over 3,500 widely-distributed species, categorized into 515 genera, encompassing a diverse range of morphologies and ecologies. This diversity is likely attributable to their distinctive morphology, which has allowed them to populate a wide range of habitat types within most major ecosystems. In my first chapter, I provide the largest-yet estimate of the snake tree of life using maximum likelihood on a supermatrix of 1745 taxa (1652 snake species + 7 outgroup taxa) and 9,523 base pairs from 10 loci (5 nuclear, 5 mitochondrial), including previously unsequenced genera (2) and species (61). I then …


Is Cortex Necessary?, Sean Allen-Hermanson 2016 Florida Int'l University

Is Cortex Necessary?, Sean Allen-Hermanson

Animal Sentience

A key contention of Klein & Barron (2016) is that consciousness does not depend on cortical structures. A critical appraisal suggests they have overestimated the strength of their evidence.


Who Is A Person? Whoever You Want It To Be, Gwen J. Broude 2016 Vassar College

Who Is A Person? Whoever You Want It To Be, Gwen J. Broude

Animal Sentience

Rowlands provides an expanded definition of personhood that preserves the requirement of unity of mental life from the orthodox definition but argues that implicit unity of mind is sufficient for conferring personhood. This allows more or all animals to be considered persons. Implicit unity of mind may be a bridge too far for those who endorse the orthodox account of personhood, and for good reasons. More fundamentally, who gets to decide what personhood entails or that personhood per se matters to such other issues as who receives legal or moral status and consideration? Perhaps we should worry less about definitions …


Are Insects Sentient?, Michael Tye 2016 University of Texas, Austin

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 2016 Tilburg University

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 2016 retired, no institutional affiliation

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 2016 University of Groningen

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.


Reflexivity: A First Demonstration, Melissa Jane Swisher 2016 Purdue University

Reflexivity: A First Demonstration, Melissa Jane Swisher

Open Access Dissertations

Currently, the emergent relation of reflexivity after training a set of baseline relations has not been demonstrated with any animal—human or nonhuman. True reflexivity can only be demonstrated if no identity (i.e., physically matching stimulus) relations are trained. In six experiments, the emergence of reflexivity and its opposite, anti-reflexivity, were explored. Pigeons received concurrent successive matching training on two or three arbitrary tasks: AB hue-form and BC form-hue (and AC hue-hue) matching. Once they had acquired these tasks, they were tested for BB (form-form) reflexivity or BB’ (form-form) anti-reflexivity matching. Most (10 of 13) pigeons that received three arbitrary tasks …


Analysis Of The Intricacies Of Substrate Recognition Of High Mobility Group Proteins And Aminoacyl-Trna Synthetases Using Non-Cognate Substrates, Douglas Van Iverson II 2016 University of Southern Mississippi

Analysis Of The Intricacies Of Substrate Recognition Of High Mobility Group Proteins And Aminoacyl-Trna Synthetases Using Non-Cognate Substrates, Douglas Van Iverson Ii

Dissertations

The studies presented in section 1 (Chapters I-IV) focus on the design and development of nucleic acid four-way junctions (4WJs) to target a member of the high mobility group (HMG) proteins, the proinflammatory cytokine high mobility group box 1 protein (HMGB1). In the present study, hybrid PNA-DNA 4WJs based on a model DNA 4WJ were constructed to improve the thermal stability of 4WJs while maintaining strong binding affinity toward HMGB1. An electrophoretic mobility shift assay (EMSA) was used to examine the binding affinity of an isolated DNA binding domain of HMGB1, the HMGB1 b-box (HMGB1b), toward a set of PNA-DNA …


Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere 2016 Psychology, University of Lethbridge

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 2016 University of British Columbia

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 …

Graemeloweus, A New Scorpion Genus From Northern California, Usa (Scorpiones: Vaejovidae), Michael E. Soleglad, Victor Fet, Matthew R. Graham, Richard F. Ayrey

Euscorpius

Genus Graemeloweus, gen. nov. (Scorpiones: Vaejovidae) is described from northern California, USA. The genus is composed of three species formerly placed in Pseudouroctonus: Graemeloweus iviei (Gertsch et Soleglad, 1972), comb. nov. (type species), G. glimmei (Hjelle, 1972), comb. nov., and G. maidu (Savary et Bryson, 2016), comb. nov. Major diagnostic characters of Graemeloweus include a non-bifurcated primary lamellar hook, the presence of a secondary lamellar hook, a complex mating plug with a two part base and an asymmetric crescent-shape barb, and the presence of a well-developed ventromedian (V2) carina on the pedipalp chela. Evidence is presented suggesting that …


Animals Are Agents, Linda A.W. Brakel 2016 University of Michigan

Animals Are Agents, Linda A.W. Brakel

Animal Sentience

Mark Rowlands’s (2016) target article invites us to consider individuals in a broad subset of the non-human animal world as genuine persons. His account features animals reacting to salient environmental stimuli as Gibsonian affordances, which is indicative of “pre-reflective self-awareness.” He holds that such pre-reflective self-awareness is both “immune to error through misidentification” (Shoemaker, 1968) and a necessary precursor to reflective consciousness and personhood. I agree. In this commentary I hope to extend Rowlands’s work with a view in which agency is an even more fundamental precursor and one can (and should) consider individuals throughout the entire animal kingdom as …
