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 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.

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 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. In this process, the study addresses the dilemma of religiosity versus spirituality faced by researchers in this area, 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, 3–21) and is corroborated by factor analysis of multiple samples, and participants representing three major world faith traditions.

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)

Flesh of My Flesh is a collection of articles by today's most respected scientists, philosophers, bioethicists, theologians, and law professors about whether we should allow human cloning.

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.

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.

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)

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)

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)

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)

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.

Gallileo described the universe in his most famous line: "This grand book is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures." Why should the laws of nature be subject to statement in such elegantly basic algebra? Why does gravity work by the principle of inverse squares? Why do simple geometrics pervade nature--from the hexagons of the honeycomb, to the complex architecture of crystals? D'Arcy Thompson, author of Growth and Form and my earliest (...) intellectual hero (along with my father and Charles Darwin), wrote that "the harmony of the world is made manifest in Form and Number, and the heart and soul and all the poetry of Natural Philosophy are embodied in the concept of math ematical beauty." Many scientists, if only to coin a striking metaphor, depict a creating God as a mathematician from the realm of Plato or Pythagoras. The physicist James Jeans wrote: "From the intrinsic evidence of his creation, the Great Architect of the Universe now begins to appear as a pure mathematician.". (shrink)

I describe a distinctive kind of fear that is generated by a vivid recognition of one’s mortal nature. I name it ‘existential shock’. This special fear does not take our future annihilation as any kind of harm, whether intrinsic or extrinsic. One puzzling feature of existential shock is that it is experienced as disclosing an important truth, yet attempts to specify this revelatory content bring us back to familiar facts about one’s inevitable death. But how can I discover something that (...) I already knew? I argue that in our everyday lives, we are in the grip of deeply entrenched patterns of thought and feeling that prevent the knowledge of our mortality from being fully assimilated. Rather, we merely ‘pay lip service’ to the facts of our mortality. I propose that existential shock involves a distinctive mode of presentation of oneself as a mortal being, in a way that cuts through subtle layers of denial that govern our lives. I develop this thesis by utilizing and synthesizing ideas from several traditions, including the work of Samuel Scheffler, Mark Johnston, Martin Heidegger, and Jay L. Garfield. (shrink)

Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859. This entry first formulates ‘Darwin's Darwinism’ in terms of five philosophically distinctive themes: (i) probability and chance, (ii) the nature, power and scope of selection, (iii) adaptation and teleology, (iv) nominalism vs. essentialism about species and (v) the tempo and mode of evolutionary change. Both Darwin and (...) his critics recognized that his approach to evolution was distinctive on each of these topics, and it remains true that, though Darwinism has developed in many ways unforeseen by Darwin, its proponents and critics continue to differentiate it from other approaches in evolutionary biology by focusing on these themes. This point is illustrated in the second half of the entry by looking at current debates in the philosophy of evolutionary biology on these five themes, with a special focus on Stephen Jay Gould's The Structure of Evolutionary Theory.

In this volume honouring Robert Pippin, prominent philosophers such as John McDowell, Slavoj Žižek, Jonathan Lear, and Axel Honneth explore Hegel's proposals concerning the historical character of philosophy. Hegelian doctrines discussed include the purported end of art, Hegel's view of human history, including the history of philosophy as the history of freedom, and the nature of self-consciousness as realized in narrative or in action. Hegel scholars Rolf-Peter Horstmann, Sally Sedgwick, Terry Pinkard, and Paul Redding attempt to vindicate some of Hegel's (...) claims concerning historical philosophical progress, while others such as Robert Stern, Christoph Menke, and Jay Bernstein suggest that Hegel either did not conceive of philosophy as progressing unidirectionally or did not make good on his claims to progress: perhaps we should still be Aristotelians in ethics, or perhaps we are still torn between sensibility and reason, or between individuality and social norms. Perhaps capitalism has exacerbated such problems. (shrink)
