Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

This book approaches Hobbes's philosophy from a completely new perspective: his creativity. Creativity is the production of something which experts consider to be original, valuable and of high quality. James Hamilton explores Hobbes's creativity by focusing on his development, personality, and motivation in the context of his culture and environment, and on the ways in which he thought creatively, as inferred from his writings. Identification of the ideas which Hobbes drew upon is an important part of the study for (...) two reasons. First, they are necessary to determine which of Hobbes's ideas and theories are original and which are not. Second, analysis of his creativity requires an understanding of the ideas from which he drew. Hamilton concludes that Hobbes became a great philosopher because of his creative virtuosity. (shrink)

This article reviews models of the cerebellum and motor learning, from the landmark papers by Marr and Albus through those of the present time. The unique architecture of the cerebellar cortex is ideally suited for pattern recognition, but how is pattern recognition incorporated into motor control and learning systems? The present analysis begins with a discussion of exactly what the cerebellar cortex needs to regulate through its anatomically defined projections to premotor networks. Next, we examine various models showing how the (...) microcircuitry in the cerebellar cortex could be used to achieve its regulatory functions. Having thus defined what it is that Purkinje cells in the cerebellar cortex must learn, we then evaluate theories of motor learning. We examine current models of synaptic plasticity, credit assignment, and the generation of training information, indicating how they could function cooperatively to guide the processes of motor learning.

Donation after circulatory determination of death (DCDD) is an accepted practice in the United States, but heart procurement under these circumstances has been debated. Although the practice is experiencing a resurgence due to the recently completed trials using ex vivo perfusion systems, interest in thoracoabdominal normothermic regional perfusion (TA-NRP), wherein the organs are reanimated in situ prior to procurement, has raised many ethical questions. We outline practical, ethical, and equity considerations to ensure transplant programs make well-informed decisions about TA-NRP. We (...) present a multidisciplinary analysis of the relevant ethical issues arising from DCDD-NRP heart procurement, including application of the Dead Donor Rule and the Uniform Definition of Death Act, and provide recommendations to facilitate ethical analysis and input from all interested parties. We also recommend informed consent, as distinct from typical “authorization,” for cadaveric organ donation using TA-NRP. (shrink)

In 1962, the philosopher Richard Taylor used six commonly accepted presuppositions to imply that human beings have no control over the future. David Foster Wallace not only took issue with Taylor's method, which, according to him, scrambled the relations of logic, language, and the physical world, but also noted a semantic trick at the heart of Taylor's argument. _Fate, Time, and Language_ presents Wallace's brilliant critique of Taylor's work. Written long before the publication of his fiction and essays, Wallace's thesis (...) reveals his great skepticism of abstract thinking made to function as a negation of something more genuine and real. He was especially suspicious of certain paradigms of thought-the cerebral aestheticism of modernism, the clever gimmickry of postmodernism-that abandoned "the very old traditional human verities that have to do with spirituality and emotion and community." As Wallace rises to meet the challenge to free will presented by Taylor, we witness the developing perspective of this major novelist, along with his struggle to establish solid logical ground for his convictions. This volume, edited by Steven M. Cahn and Maureen Eckert, reproduces Taylor's original article and other works on fatalism cited by Wallace. James Ryerson's introduction connects Wallace's early philosophical work to the themes and explorations of his later fiction, and Jay Garfield supplies a critical biographical epilogue. (shrink)

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data‐fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general‐purpose method for analyzing and comparing all classes of cognitive models. PSP (...) is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.

The present study focuses on furthering the theoretical foundations of the field of spirituality and religiosity in the workplace (SRW) by providing a parsimonious definition, and multi-dimensional model for the construct of spirituality grounded in a pluralistic and historically authentic framework using the Sophia Perennis or Perennial Philosophy (Lings, 2005, A return to the spirit.... Fons Vitae, Louisville). In this process, the study addresses the dilemma of religiosity versus spirituality faced by researchers in this area (Benefiel, Fry, & Geigle, 2014, (...) Psychology of Religion and Spirituality, 6(3), 175). It also addresses concerns regarding the potential conflicts related to spirituality and religiosity that could arise in a secular workplace, which emphasizes inclusiveness and equality. A three factor model of spirituality is developed using the grounded theory approach (Corbin & Strauss, 1990, Qualitative Sociology, 13(1), 3–21) and is corroborated by factor analysis of multiple samples ( n = 159 and n = 181), and participants representing three major world faith traditions (both Eastern and Western).

Do the rich descriptions and narrative shapings of literature provide a valuable resource for readers, writers, philosophers, and everyday people to imagine and confront the ultimate questions of life? Do the human activities of storytelling and complex moral decision-making have a deep connection? What are the moral responsibilities of the artist, critic, and reader? What can religious perspectives—from Catholic to Protestant to Mormon—contribute to literary criticism? Thirty well known contributors reflect on these questions, including iterary theorists Marshall Gregory, James (...) Phelan, and Wayne Booth; philosophers Martha Nussbaum, Richard Hart, and Nina Rosenstand; and authors John Updike, Charles Johnson, Flannery O'Connor, and Bernard Malamud. Divided into four sections, with introductory matter and questions for discussion, this accessible anthology represents the most crucial work today exploring the interdisciplinary connections between literature, religion and philosophy.

Visual word recognition is facilitated by the presence of orthographic neighbors that mismatch the target word by a single letter substitution. However, researchers typically do not consider where neighbors mismatch the target. In light of evidence that some letter positions are more informative than others, we investigate whether the influence of orthographic neighbors differs across letter positions. To do so, we quantify the number of enemies at each letter position (how many neighbors mismatch the target word at that position). Analyses (...) of reaction time data from a visual word naming task indicate that the influence of enemies differs across letter positions, with the negative impacts of enemies being most pronounced at letter positions where readers have low prior uncertainty about which letters they will encounter (i.e., positions with low entropy). To understand the computational mechanisms that give rise to such positional entropy effects, we introduce a new computational model, VOISeR (Visual Orthographic Input Serial Reader), which receives orthographic inputs in parallel and produces an over‐time sequence of phonemes as output. VOISeR produces a similar pattern of results as in the human data, suggesting that positional entropy effects may emerge even when letters are not sampled serially. Finally, we demonstrate that these effects also emerge in human subjects' data from a lexical decision task, illustrating the generalizability of positional entropy effects across visual word recognition paradigms. Taken together, such work suggests that research into orthographic neighbor effects in visual word recognition should also consider differences between letter positions. (shrink)

Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically has addressed this question using limited human data that are restricted to semantic similarity and/or general semantic relatedness. We tested eight DSMs that are popular in current cognitive and psycholinguistic research (positive pointwise mutual information; global vectors; and three variations each of Skip-gram and continuous bag of words (CBOW) (...) using word, context, and mean embeddings) on a theoretically motivated, rich set of semantic relations involving words from multiple syntactic classes and spanning the abstract–concrete continuum (19 sets of ratings). We found that, overall, the DSMs are best at capturing overall semantic similarity and also can capture verb–noun thematic role relations and noun–noun event-based relations that play important roles in sentence comprehension. Interestingly, Skip-gram and CBOW performed the best in terms of capturing similarity, whereas GloVe dominated the thematic role and event-based relations. We discuss the theoretical and practical implications of our results, make recommendations for users of these models, and demonstrate significant differences in model performance on event-based relations.

Joseph Margolis’ philosophical work is both sanguine and fair. It is sanguine because much of it captures the inherent worth and dignity of the human condition. This includes aesthetics, anthropological diversity and history, the diversity of cognitive orientations and objectivity without foundations. Margolis embraces science and naturalism without reductionism. His pragmatism, though, is rooted more in James’ perspectivism, his local nice adaptation, and his relativism than that of Peirce and Dewey and their sense of science and the community of (...) inquirers. Margolis’ strength is his attempt to reconcile positions and his fairness towards others as he tries to wedge his pragmatist position amid others. But he celebrates the subjective stance of James, and downplayed the communal sense of Peirce and Dewey so vital to epistemic advances. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Avatars of the Word: From Papyrus to CyberspaceJay David BolterJames J. O'Donnell. Avatars of the Word: From Papyrus to Cyberspace. Cambridge: Harvard University Press, 1998. xiv + 210 pp. 1 ill. Cloth, $24.95.The last chapter of James O'Donnell's thoughtful and highly readable book is entitled "Cassiodorus: Or, The Life of the Mind in Cyberspace." The subtitle made me think of the cyberenthusiast John Perry Barlow's claim that (...) cyberspace is in fact the new home of Mind. In a brief tract published on the Internet a few years ago, "A Declaration of Independence for Cyberspace," Barlow claimed that cyberspace is a new world, freed from the prejudices and traditions of the cultures of our physical world. Barlow is in many ways O'Donnell's opposite number. Where Barlow, like so many other proponents of cyberspace, rejects the relevance of history for our electronic future, O'Donnell anchors every step of his analysis in the history of writing. Where Barlow is frenetic, O'Donnell is calm. O'Donnell considers electronic writing as the latest in a series of technologies of writing, each responding to and shaped by its contemporary culture. The main lines of O'Donnell's argument--his comparison of contemporary literate culture to earlier cultures of the papyrus roll, the codex, and the printed book--are familiar from other sources. But O'Donnell's profound and easy learning enables him to add fresh insights and examples on every issue.O'Donnell's strategy is to explain the meaning of electronic writing today through a series of historical resonances. Early chapters examine the passage from orality to literacy as represented by the contrasting philosophical presences of Socrates and Plato; the changing nature of the library from the Alexandrian through Cassiodorus and the medieval monastic library and on to the hopes for today's "virtual" library; and the techniques of reading and reference [End Page 334] afforded by various technologies from the papyrus roll to the codex to the homepage. In later chapters O'Donnell explores the nature of teaching and of the university today and speculates on their future, as electronic technologies become more important to the curriculum. His specialist's knowledge of late antiquity and the early Middle Ages permits him to concentrate on this crucial period, which witnessed the shift from papyrus roll to codex. The historian of the book Roger Chartier has also argued that this transfer from roll to codex is the most appropriate comparison for the current move from printed book to electronic text. O'Donnell devotes relatively little space to discussing the latest avatar, electronic technology itself; he concentrates instead on establishing the historical parallels.In short, what is usually lacking in discussions of electronic writing, an informed historical sense, is in ample supply in Avatars of the Word. O'Donnell is in general optimistic about the future of literate culture. His optimism seems to come precisely from his long historical view, which mitigates any feeling of panic over the current changes in the forms and practices of literacy. In this respect we might compare his cautious optimism with the less informed pessimism of Sven Birkerts in his Gutenberg Elegies (1994). O'Donnell is also sanguine about the role that electronic technology can play in education--not by replacing teachers, but rather by allowing instruction to become more individual.On the other hand, the historical sophistication of Avatars of the Word both defines and limits its audience. Enthusiasts like John Perry Barlow count their readers in the hundreds of thousands, precisely because they offer a high-energy narrative of the future that does not trouble itself about the past. The leisurely and reflective pace of O'Donnell's book will seem luxurious to most of the new media world. O'Donnell says that his audience are "those who read books and use computers and wonder about the relationship" (ix). But the audience is perhaps narrower: those who, like the readers of this journal, are steeped in literate culture. Even within that group, O'Donnell is really speaking to those who are not intimidated by or disdainful of computer technology.In addition to being a professor of... (shrink)

William James’s lead continues to provide a balancing act of inquiry and truth with plurality and conflict. First, this article considers this balancing act in neuroscience, both what we have been learning since James published The Principles of Psychology and in how neuroscience is done. As pragmatists have long argued against dualisms and absolutes, the authors situate contemporary understanding in its historical context. Humans have evolved as brains-in-bodies-in-cultures and navigate such worlds through good-enough strategies, not a disembodied reason. (...) Embodied intelligence is laden with instinct, habit, and emotion as much as it is about consciousness. Truth, for James, is focused on nuanced success outcomes, both modest and broad. James’s sense of fallibility is critical in terms of comfort and discomfort in a social group. More prosocial behavior tends to be honest and less sociopathic, of course unless it is myopic and only in group orientation, which it often is. Understanding ourselves through the neuroscience does not answer most of the questions nor solve all the problems. However, such understanding is an important tool in aiding our coping efforts, especially regarding contemporary life. (shrink)

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

ABSTRACTTwo new books about the Pragmatist tradition, Richard Bernstein's The Pragmatic Turn and Colin Koopman's Pragmatism as Transition, represent respectively a summing up of the past half‐century of the tradition's history and a possible program for its future development. Bernstein ecumenically considers the achievements of a wide range of thinkers from Peirce, Dewey, and James to Brandom, Putnam, and Rorty, drawing valuable lessons from each, while not sparing criticism of their flaws. Koopman also tries to bridge the gap between (...) what he calls “classicopragmatism” and “neopragmatism,” although he finds more to admire in Rorty than in his predecessors. Whereas Bernstein attempts to supplement the pragmatist tradition by turning to Habermas, Koopman finds his inspiration in Foucault. Both authors emphasize the historicist, evolutionary, and transitionalist implications of pragmatism, paying as a result insufficient attention to the historical possibilities of repetition, rupture, discontinuity, and the unexpected event. In terms of the political implications they draw, Koopman advocates a meliorist incrementalism that lacks any real bite, while Bernstein expresses dissatisfaction with the democratic pieties of Rorty's final work, but doesn't really provide a sustained alternative.

Origin of Species was published; he approached the end of his life just before Albert Einstein presented us with General Relativity. His lifetime saw the emergence of psychology as a discipline separate from philosophy, a birth attended by philosopher-psychologists such as his good friend William James. The work of Peirce, like that of the other American Pragmatists, reflects the ferment of the times. His thought bears the imprint of science, not the science of that Nineteenth Century which as Loren (...) Eiseley has remarked, "regarded the 'laws' of nature as imbued with a kind of structural finality, an integral determinism, which it was the scientists’ duty to describe," (Eisele, 1971) but rather, of science as open, as intrinsically revisable, as radically empirical. Working from the model of science in this latter sense, Peirce held that philosophy, and indeed logic.. (shrink)

Many philosophers accept that ought implies can (OIC), but it is not obvious that we have a good argument for that principle. I consider one sort of argument for it, which seems to be a development of an Aristotelian idea about practical deliberation and which is endorsed by, amongst others, R. M. Hare and James Griffin. After briefly rehearsing some well-known objections to that sort of argument (which is based on the supposed pointlessness of impossible obligations), I present a (...) further objection, based on a maximally charitable reading of the argument, and conclude that nobody ought to think that it gives them a reason to accept OIC.

From Bishop Wilberforce in the 1860s to the advocates of "creation science" today, defenders of traditional mores have condemned Darwin's theory of evolution as a threat to society's values. Darwin's defenders, like Stephen Jay Gould, have usually replied that there is no conflict between science and religion--that values and biological facts occupy separate realms. But as James Rachels points out in this thought-provoking study, Darwin himself would disagree with Gould. Darwin, who had once planned on being a clergyman, was (...) convinced that natural selection overthrew our age-old religious beliefs. Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. James Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science. Western philosophy and religion, Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers. Kant's famous argument that suicide reduces one to the level of an animal, for instance, is meaningless if humans are, in fact, animals. Indeed, humanity's membership in the animal kingdom calls into question the classic notions of human dignity and the sacredness of human life. What we need now, Rachels contends, is a philosophy that does not discriminate between different species, one that addresses each being on an individual basis. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Vibrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights. (shrink)

In what may be the most radical business book ever published, philosopher Jay Ogilvy shows that living without a goal is the only way to accomplish anything. In the 1980s we ran our lives with all the direction and confidence filofaxes and to-do lists could provide. Always knowing exactly where we were headed, we climbed toward the goals corporate America held out in front of us like so many carrots: higher salaries, better titles, more impressive offices. But after a decade (...) of climbing, the air is getting thin. We crave the chance to create, to express ourselves, and to make a difference, not just a living. It is time, says businessman/philosopher James Ogilvy, to tear up the to-do lists and grant ourselves the freedom to enjoy what E. M. Forster calls "the lights and shades that exist in the greyest conversation." Ogilvy shows that richness and color and flavor flood back into our lives once we set aside the goals that hold us captive. He explores how philosophers (from Plato to Nietzsche), lovers, ideologues, and executives have at one time or another lived without goals. What emerges from his argument is a new look at how to achieve personal creativity and freedom by fashioning one's day to-day life, not as a larger goal-producing machine, but as a personal work of art.
