The proposed multilevel framework of discourse comprehension includes the surface code, the textbase, the situation model, the genre and rhetorical structure, and the pragmatic communication level. We describe these five levels when comprehension succeeds and also when there are communication misalignments and comprehension breakdowns. A computer tool has been developed, called Coh-Metrix, that scales discourse (oral or print) on dozens of measures associated with the first four discourse levels. The measurement of these levels with an automated tool helps researchers track (...) and better understand multilevel discourse comprehension. Two sets of analyses illustrate the utility of Coh-Metrix in discourse theory and educational practice. First, Coh-Metrix was used to measure the cohesion of the text base and situation model, as well as potential extraneous variables, in a sample of published studies that manipulated text cohesion. This analysis helped us better understand what was precisely manipulated in these studies and the implications for discourse comprehension mechanisms. Second, Coh-Metrix analyses are reported for samples of narrative and science texts in order to advance the argument that traditional text difficulty measures are limited because they fail to accommodate most of the levels of the multilevel discourse comprehension framework.

Most areas of the cognitive and social sciences assume that knowledge representations are constructed and used during communication and that much of its content is social. Those of us who build computer models of comprehension and conversation are forced to be explicit about the nature of these knowledge representations and affiliated processes. There are some conditions when knowledge is not sufficiently social, and other conditions when knowledge is overly grounded in social mechanisms. The argument is advanced that constraints, coherence, and (...) precision are very much at the heart of an explanation of the nature and amount of social knowledge. Asocial content reigns supreme when the referential world knowledge is highly constrained, coherently structured, and precisely specified. The social context of knowledge construction becomes progressively more influential to the extent to that world knowledge is vague, open-ended, imprecise, underspecified, and fragmentary. (shrink)

Researchers in the field of discourse processing have investigated how mental models are constructed when adults comprehend stories. They have explored the process of encoding various classes of inferences “on-line” when these mental microworlds are constructed during comprehension. This commentary addresses the extent to which these inferences and mental microworlds are “embodied.”.

It is often assumed that engaging in a one‐on‐one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) (...) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5‐step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural‐language‐based computer tutoring (Why2‐Atlas and Why2‐AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text‐based control conditions.

Top-down dynamical models of cognitive processes, such as the one presented by Thelen et al., are important pieces in understanding the development of cognitive abilities in humans and biological organisms. Unlike standard symbolic computational approaches to cognition, such dynamical models offer the hope that they can be connected with more bottom-up, neurologically inspired dynamical models to provide a complete view of cognition at all levels. We raise some questions about the details of their simulation and about potential limitations of top-down (...) dynamical models. (shrink)

The meanings of abstract concepts depend on context. Perceptual symbol systems (PSS) provide a powerful framework for representing such context. Whereas a few expected difficulties for simulations are consistent with empirical findings, the theory does not clearly predict simulations of specific abstract concepts in a testable way and does not appear to distinguish abstract noun concepts (like truth) from their stem concepts (such as true).

Schyns, Goldstone & Thibaut present reasonable arguments for feature creation in category learning. We argue, however, that they do not provide unequivocal evidence either for the necessity or for the occurrence of feature creation. In an effort to sharpen the debate, we take the stand that a fixed feature approach is to be preferred in the absence of compelling evidence.

Cognitive scientists have a variety of approaches to studying cognition: experimental psychology, computer science, robotics, neuroscience, educational psychology, philosophy of mind, and psycholinguistics, to name but a few. In addition, they also differ in their approaches to cognition - some of them consider that the mind works basically like a computer, involving programs composed of abstract, amodal, and arbitrary symbols. Others claim that cognition is embodied - that is, symbols must be grounded on perceptual, motoric, and emotional experience. The existence (...) of such different approaches has consequences when dealing with practical issues such as understanding brain disorders, designing artificial intelligence programs and robots, improving psychotherapy, or designing instructional programs. The symbolist and embodiment camps seldom engage in any kind of debate to clarify their differences. This book is the first attempt to do so. It brings together a team of outstanding scientists, adopting symbolist and embodied viewpoints, in an attempt to understand how the mind works and the nature of linguistic meaning. As well as being interdisciplinary, all authors have made an attempt to find solutions to substantial issues beyond specific vocabularies and techniques. (shrink)

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical (...) possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self‐organized distinction when learning temporal relations between events with overlap versus those without. (shrink)

Hegel has identified what I have preemptively designated a third aesthetic realm--in addition to natural beauty and artistic beauty--one greatly connected with human life . . . art applied to the enhancement of life . . . But the other border of what I shall designate the Third Realm is equally non-exclusionary, especially when we consider what Hegel singles out under the head of beautiful people--the kind of beauty possessed by Helen of Troy, say, which we must suppose a wonder (...) of nature. But Helen's choice of hairstyles, makeup, or garments would have belonged to the Third Realm, since it would have been chosen for enhancement, like the setting of a jewel. (shrink)

Under the label of scientific metaphysics, many naturalist metaphysicians are moving away from a priori conceptual analysis and instead seek scientific explanations that will help bring forward a unified understanding of the world. This paper first reviews how our classical assumptions about ordinary objects fail to be true in light of quantum mechanics. The paper then explores how our experiences of ordinary objects arise by reflecting on how our neural system operates algorithmically. Contemporary models and simulations in computational neuroscience are (...) shown to provide a theoretical framework that does not conflict with existing fundamental physical theories, and nonetheless helps us make sense of the manifest image. It is argued that we must largely explain how the manifest image arises in algorithmic terms, so that we can pursue a metaphysics about ordinary objects that is scientifically well founded. (shrink)

In The Abuse of Beauty, art critic and philosopher Arthur Danto explains how the notion of beauty as anathema to art arose and flourished and offers a new way of looking at art and beauty. He draws on the thought of artists, critics, and philosophers such as Rimbaud, Fry, Matisse, and Greenberg, to reposition beauty as one of many modes -- along with sexuality, sublimity, disgust, and horror -- through which the human sensibility expresses itself. 20 black-and-white illustrations are (...) included.

What is it to be a work of art? Renowned author and critic Arthur C. Danto addresses this fundamental, complex question. Part philosophical monograph and part memoiristic meditation, _What Art Is _challenges the popular interpretation that art is an indefinable concept, instead bringing to light the properties that constitute universal meaning. Danto argues that despite varied approaches, a work of art is always defined by two essential criteria: meaning and embodiment, as well as one additional criterion contributed by the (...) viewer: interpretation. Danto crafts his argument in an accessible manner that engages with both philosophy and art across genres and eras, beginning with Plato’s definition of art in _The Republic_, and continuing through the progress of art as a series of discoveries, including such innovations as perspective, chiaroscuro, and physiognomy. Danto concludes with a fascinating discussion of Andy Warhol’s famous shipping cartons, which are visually indistinguishable from the everyday objects they represent. Throughout, Danto considers the contributions of philosophers including Descartes, Kant, and Hegel, and artists from Michelangelo and Poussin to Duchamp and Warhol, in this far-reaching examination of the interconnectivity and universality of aesthetic production.

Now in its third edition, _Narration and Knowledge_ is a classic work exploring the nature of historical knowledge and its reliance on narrative. Analytical philosopher Arthur C. Danto introduces the concept of "narrative sentences," in which an event is described with reference to later events and discusses why such sentences cannot be understood until the later event happens. Danto compares narrative and scientific explanation and explores the legitimacy of historical laws. He also argues that history is an autonomous and (...) humanist discipline incapable of being reduced to scientific descriptions. Lydia Goehr's new introduction illustrates Danto's main arguments by questioning her very role, first, as an introducer of a book that has not yet been read by readers and, second, as an interpreter of a book written forty years ago. Frank Ankersmit's conclusion revisits the initial impact of the publication of _Narration and Knowledge_ and considers its enduring legacy. (shrink)

A study of the philosophical problems associated with the concept of action. Professor Danto is concerned to isolate logically the notion of a 'basic action' and to examine the way in which context and intention, for example, can convert physiological movements into significant actions. He finds many suggestive parallels between the concepts - the logical architecture - of action and cognition and in developing this theme he becomes involved in and proposes new approaches to various long-standing problems connected with causality, (...) determinism and materialism. As in his earlier books, Analytical Philosophy of History and Analytical Philosophy of Knowledge, Professor Danto places the discussion in a broad historical and philosophical perspective and brings to it a wide reading and an unusual range of interests. He is always prepared to venture novel ideas to stimulate further debate and research and the book as a whole is presented as an original contribution to a subject which is attracting increasing attention from philosophers and from psychologists with an interest in the conceptual assumptions behind their work.

Few philosophers are as widely read or as widely misunderstood as Friedrich Nietzsche. When Danto's classic study was first published in 1965, many regarded Nietzsche as a brilliant but somewhat erratic thinker. Danto, however, presented a radically different picture, arguing that Nietzsche offered a systematic and coherent philosophy that anticipated many of the questions that define contemporary philosophy. Danto's clear and insightful commentaries helped canonize Nietzsche as a philosopher and continue to illuminate subtleties in Nietzsche's work as well as his (...) immense contributions to the philosophies of science, language, and logic. This new edition, which includes five additional essays, not only further enhances our understanding of Nietzsche's philosophy; it responds to the misunderstandings that continue to muddy his intellectual reputation. Even today, Nietzsche is seen as everything from a precursor of feminism and deconstruction to a prophetic writer and spokesperson for disgruntled teenage boys. As Danto points out in his preface, Nietzsche's writings have purportedly inspired recent acts of violence and school shootings. Danto counters these misreadings by elaborating an anti-Nietzschian philosophy from within Nietzsche's own philosophy "in the hope of disarming the rabid Nietzsche and neutralizing the vivid frightening images that have inspired sociopaths for over a century." The essays also consider specific works by Nietzsche, including _Human, All Too Human_ and _The Genealogy of Morals_, as well as the philosopher's artistic metaphysics and semantical nihilism.
