The sounds that make up spoken words are heard in a series and must be mapped rapidly onto words in memory because their elements, unlike those of visual words, cannot simultaneously exist or persist in time. Although theories agree that the dynamics of spoken word recognition are important, they differ in how they treat the nature of the competitor set—precisely which words are activated as an auditory word form unfolds in real time. This study used eye tracking to measure the (...) impact over time of word frequency and 2 partially overlapping competitor set definitions: onset density and neighborhood density. Time course measures revealed early and continuous effects of frequency (facilitatory) and on set based similarity (inhibitory). Neighborhood density appears to have early facilitatory effects and late inhibitory effects. The late inhibitory effects are due to differences in the temporal distribution of similarity within neighborhoods. The early facilitatory effects are due to subphonemic cues that inform the listener about word length before the entire word is heard. The results support a new conception of lexical competition neighborhoods in which recognition occurs against a background of activated competitors that changes over time based on fine-grained goodness-of-fit and competition dynamics.

The complex-systems approach to cognitive science seeks to move beyond the formalism of information exchange and to situate cognition within the broader formalism of energy flow. Changes in cognitive performance exhibit a fractal (i.e., power-law) relationship between size and time scale. These fractal fluctuations reflect the flow of energy at all scales governing cognition. Information transfer, as traditionally understood in the cognitive sciences, may be a subset of this multiscale energy flow. The cognitive system exhibits not just a single power-law (...) relationship between fluctuation size and time scale but actually exhibits many power-law relationships, whether over time or space. This change in fractal scaling, that is, multifractality, provides new insights into changes in energy flow through the cognitive system. We survey recent findings demonstrating the role of multifractality in (a) understanding atypical developmental outcomes, and (b) predicting cognitive change. We propose that multifractality provides insights into energy flows driving the emergence of cognitive structure. (shrink)

People spontaneously discover new representations during problem solving. Discovery of a mathematical representation is of special interest, because it shows that the underlying structure of the problem has been extracted. In the current study, participants solved gear‐system problems as part of a game. Although none of the participants initially used a mathematical representation, many discovered a parity‐based, mathematical strategy during problem solving. Two accounts of the spontaneous discovery of mathematical strategies were tested. According to the automatic schema abstraction hypothesis, experience (...) with multiple, unique problem exemplars facilitates extraction of the parity relation. According to the comparison‐based abstraction hypothesis, explicitly comparing gear pathways that have different number, but the same parity, should result in extraction of parity. An event history analysis showed that accumulation of experiences with different‐number, same‐parity comparisons predicted discovery of parity; accumulation of unique exemplars did not. Results suggest that comparison‐based abstraction processes can lead to the discovery of a mathematical relation. (shrink)

Gestures and speech are clearly synchronized in many ways. However, previous studies have shown that the semantic similarity between gestures and speech breaks down as people approach transitions in understanding. Explanations for these gesture–speech mismatches, which focus on gestures and speech expressing different cognitive strategies, have been criticized for disregarding gestures’ and speech's integration and synchronization. In the current study, we applied three different perspectives to investigate gesture–speech synchronization in an easy and a difficult task: temporal alignment, semantic similarity, and (...) complexity matching. Participants engaged in a simple cognitive task and were assigned to either an easy or a difficult condition. We automatically measured pointing gestures, and we coded participant's speech, to determine the temporal alignment and semantic similarity between gestures and speech. Multifractal detrended fluctuation analysis was used to determine the extent of complexity matching between gestures and speech. We found that task difficulty indeed influenced gesture–speech synchronization in all three domains. We thereby extended the phenomenon of gesture–speech mismatches to difficult tasks in general. Furthermore, we investigated how temporal alignment, semantic similarity, and complexity matching were related in each condition, and how they predicted participants’ task performance. Our study illustrates how combining multiple perspectives, originating from different research areas (i.e., coordination dynamics, complexity science, cognitive psychology), provides novel understanding about cognitive concepts in general and about gesture–speech synchronization and task difficulty in particular.

Thomas Jefferson and Philosophy: Essays on the Philosophical Cast of Jefferson’s Writings is a collection of essays on topics that relate to philosophical aspects of Jefferson’s thinking over the years. Much historical insight is given to ground the various philosophical strands in Jefferson’s thought and writing on topics such as political philosophy, moral philosophy, slavery, republicanism, wall of separation, liberty, educational philosophy, and architecture.

Today there is a thriving 'emotions industry' to which philosophers, psychologists and neuroscientists are contributing. Yet until two centuries ago 'the emotions' did not exist. In this path-breaking study Thomas Dixon shows how, during the nineteenth century, the emotions came into being as a distinct psychological category, replacing existing categories such as appetites, passions, sentiments and affections. By examining medieval and eighteenth-century theological psychologies and placing Charles Darwin and William James within a broader and more complex nineteenth-century setting, (...) Thomas Dixon argues that this domination by one single descriptive category is not healthy. Overinclusivity of 'the emotions' hampers attempts to argue with any subtlety about the enormous range of mental states and stances of which humans are capable. This book is an important contribution to the debate about emotion and rationality which has preoccupied western thinkers throughout the eighteenth and nineteenth centuries and has implications for contemporary debates.

In a recent paper, James Edwin Mahon argues that literary artworks—novels in particular—never lie because they do not assert. In this discussion note, I reject Mahon’s conclusion that novels never lie. I argue that a central premiss in his argument—that novels do not contain assertions—is false. Mahon’s account underdetermines the content of literary works; novels have rich layers of content and can contain what I call ‘profound’ assertions, and ‘background’ assertions. I submit that Mahon therefore fails to establish that (...) novels never lie. (shrink)

James Rachels argued against the possibility of finding some moral capacity in humans that confers upon them a unique dignity. His argument contends that Darwinism challenges such attempts, because Darwinism predicts that any morally valuable capacity able to bestow a unique dignity is likely present to a degree within both humans and non-human animals alike. I make the case, however, that some of Darwin's own thoughts regarding the nature of conscience provide a springboard for criticising Rachels's claim here. Using (...) Darwin's thoughts regarding conscience, I begin the project of grounding a revised account of human dignity in the human tendency to enshrine products of conscience within institutions. Specifically, I argue that this new account of human dignity is partly contingent upon humans creating institutions morally respectful of the values present within non-human nature. (shrink)

My paper describes a method of teaching history of modern philosophy in a way which is accessible to students with no background in philosophy. The main innovation of the course is that the readings are organized around three themes: (1) theory of knowledge; (2) philosophy of religion; (3) the free will problem. This provides continuity between the readings, a feature often missing in historical courses. Moreover, seeing how different philosophical methods--rationalism (Descartes), empiricism (Hume), pragmatism (James), and twentieth century analytic (...) philosophy (Russell)--approach the same issues deepens students' understanding of these methods.

For more than 35 years, James Welling has explored the material and conceptual possibilities of photography. Diary/Landscape - the first mature body of work by this important contemporary artist - set the framework for his subsequent investigations of abstraction and his fascination with nineteenth- and twentieth-century New England. In July 1977, Welling began photographing a two-volume travel diary kept by his great-grandmother Elizabeth C. Dixon, as well as landscapes in southern Connecticut. A beautiful and moving meditation on family, (...) history, memory, and place, the work reintroduced history and private emotion as subjects in high art, while also helping to usher in the centrality of photography and theoretical questions about originality that mark the epochal Pictures Generation.

Competing perspectives on the nature of emotion are illustrated with latent and emergent variable models. Latent variable models draw from classical test theory, assuming that the measured indicators of emotion covary by virtue of some common executive, organizing neural circuit or network in the brain. By contrast, emergent variable models draw from a theory-driven, operational definition tradition, positing that emotions do not cause, but rather are caused by, the measured indicators of emotion, assuming no executive neural circuit or network, and (...) requiring no covariation among indicators. I suggest that the emergent variable model may be more compatible with the extant literature on the nature of emotion, especially in the age of affective neuroscience. (shrink)

This paper provides a critical reconstruction of J. B. Erhard's account of recognition that locates it within the context of his revolutionary natural law theory. The first three sections lay out the foundations of Erhard's position. The fourth section outlines Erhard's response to the opponents of revolution and raises a problem for it. The fifth section argues that we can resolve this problem by drawing upon Erhard's account of failures of legal recognition. The sixth and final section considers the relevance (...) of that account for contemporary legal and political theory. (shrink)

David Hume, philosopher, historian, economist, librarian, and essayist, was one of the great figures of the European Enlightenment. Unlike some of his famous contemporaries, however, he was not dogmatically committed to idealised conceptions of reason, liberty, and progress. Instead, Hume was a sceptic whose arguments questioned the reach and authority of human rationality, and who put the rivalrous passions of commercial life at the centre of his theory of human -- -- itself. -- ABOUT THE SERIES: The Very Short Introductions (...) series from Oxford University Press contains hundreds of titles in almost every subject area.

Medicine is facing several significant challenges as the twenty-first century unfolds, which represent barriers or limitations that threaten to cripple the advancement of medicine and its practice. One of the responses to these challenges is the emergence of systems medicine. And one of the more pertinent challenges is identifying and clarifying systems medicine's conceptual and theoretical foundations. The present book represents a sustained effort to examine this challenge and to map the terrain by which to engage it and to pursue (...) possible solutions. This conceptual and theoretical challenge in particular needs to be addressed to ensure the future success of systems medicine. To that end the book explores the conceptual and theoretical foundations of systems medicine, including the major concepts of organicism, emergence, and robustness, and contrasts these concepts to those for biomedicine, including mechanism, resultant, and homeostasis. Moreover, this challenge is critical because its resolution provides the intellectual scaffolding necessary for structuring the concepts and theories required to understand and explain more adequately or completely biological, physiological, and pathological mechanisms and processes. Importantly, with a robust conceptual and theoretical scaffolding, systems medicine must be implemented interdisciplinary not only within the medical community but also within the social and political communities, which the COVID-19 pandemic made so painfully obvious.

This book develops an original and comprehensive theory of political liberalism. It defends bold new accounts of the nature of autonomy and individual liberty, the content of distributive justice, and the justification for the authority of the State. The theory that emerges integrates contemporary progressive and pluralistic liberalism into a broadly Aristotelian intellectual tradition. The early chapters of the book challenge the traditional conservative idea of individual liberty-the liberty to dispose of one's property as one wishes-and replace it with a (...) new one, according to which liberty is of equal value to all persons, regardless of economic position. The middle chapters present an original theory of socio-economic justice, arguing that a society in which every citizen enjoys an equal share of liberty should be the distributive goal of the State. It is argued that this goal is incompatible with the existence of large disparities in wealth and economic power, and that (contra conservative and libertarian economic arguments) such disparities are harmful to the overall health of national and global economies. The final chapters provide an original argument that the State has both a moral duty and a moral right to pursue this program of socio-economic justice (contra conservative and libertarian moral arguments), and that only the measures necessary to implement this program lie within the morally justifiable limits on the State's authority. Though primarily a political work, it spans most areas of practical philosophy-including ethical, social, and legal theory; and meta-ethics, moral psychology, and action theory. And though fundamentally a philosophical work, it incorporates research from a number of fields-including decision theory, economics, political science, and jurisprudence; primatology, neuroscience, and psychology; and history, anthropology, sociology, and ecology-and is sure to be of interest to a wide range of scholars and students.

By highlighting relations between experimental and theoretical work, this volume explores new ways of addressing one of the central challenges in the study of language and cognition. The articles bring together work by leading scholars and younger researchers in psychology, linguistics and philosophy. An introductory chapter lays out the background on concept composition, a problem that is stimulating much new research in cognitive science. Researchers in this interdisciplinary domain aim to explain how meanings of complex expressions are derived from simple (...) lexical concepts and to show how these meanings connect to concept representations. Traditionally, much of the work on concept composition has been carried out within separate disciplines, where cognitive psychologists have concentrated on concept representations, and linguists and philosophers have focused on the meaning and use of logical operators. This volume demonstrates an important change in this situation, where convergence points between these three disciplines in cognitive science are emerging and are leading to new findings and theoretical insights.

To approach the many challenges involved in the notion of engineering concepts, it is important to have a clear idea of the starting point – the concepts that people use in their everyday lives, in conversations and in expressing beliefs, desires, intentions and so forth. The first Section of this chapter introduces evidence that I have accumulated over the last many years concerning the flexibility, context-dependence, and vagueness of such common concepts. The concept engineer needs to understand the structure of (...) the “raw material” with which she is working. In Section 2, I summarise some results concerning the amount of individual variation that exists within a single relatively homogenous population of individuals, both in what examples are considered most typical of a category, and in what properties are considered most central to a category (Hampton & Passanisi, 2016). The demonstration of a significant degree of reliable variation in responses to these questions, that is stable over time, illustrates the potential for conceptual engineering interventions to affect individuals’ concepts. Concepts are rarely fixed or uniformly understood in the same way. I then discuss the different ways in which concepts track the world, and I speculate about how different conceptual domains are governed by different criteria of validity or acceptability. This reflection will lead to Section 3 in which I summarise some results from recent research (Thorne, Quilty-Dunn, Smortchova, Shea, & Hampton, 2021), investigating for the first time how people view the value of different familiar concepts. Knowing how people appraise concepts will be a key to developing ideas for improving the reliability and validity of the concepts that they commonly use. A final section contains some (largely speculative) discussion about the implications of work in psychology of concepts for the project of conceptual engineering. (shrink)

The popular view of non-directive genetic counseling limits the counselor's role to providing information to clients and assisting families in making decisions in a morally neutral fashion. This view of non-directive genetic counseling is shown to be incomplete. A fuller understanding of what it means to respect autonomy shows that merely respecting client choices does not exhaust the duty. Moreover, the genetic counselor/client relationship should also be governed by the counselor's commitment to the principle of beneficience. When non-directive counseling is (...) reexamined in light of both these principles, it becomes clear that there are cases in which counselors should attempt to persuade clients to reconsider their decisions. Such attempts are consistent with non-directive counseling because, while respecting the clients' decision-making authority, they insure that clients act with full knowledge of the moral consequences of their decisions.

A prominent trend in recent work on Hume’s epistemology has it that the concerns of Part Three of Book One of the Treatise, ‘Of knowledge and probability’, are purely descriptive and explanatory. Don Garrett and David Owen have argued that Hume’s primary interest lies in showing that it is not reason but rather the imagination that enables us to use experience to form beliefs about the future. Reason cannot be responsible for such beliefs; for if it were, it would have (...) to proceed by means of the principle ‘that those instances of which we have had no experience, resemble those, of which we have had experience’; and there is no source for that principle in either experience or reason itself. Of course, no belief is shown to be unjustified simply by the fact that it is produced by the imagination and not by reasoning. For Hume’s reasons for scepticism about the trustworthiness of the imagination, the reader has to wait until Part Four, and its claim that ‘there is a direct and total opposition…betwixt those conclusions we form from cause and effect, and those that persuade us of the continu’d and independent existence of body’. Louis Loeb agrees that Book One of the Treatise demands to be read as having two stages, the first constructive, the second destructive. But he has an intriguing and unusual take on the first stage. He believes that there is more to Part Three than mere description and explanation. There is in addition a theory of justification. In this part of the Treatise Hume shows himself to have a ‘pre-theoretical’ commitment to the view that, all things being equal, beliefs produced by certain belief-forming mechanisms within the faculty of imagination count as knowledge; and also seeks to give this commitment a theoretical rationale. If Loeb is right, the old view of Hume as a sceptic about induction needs to be revised even more radically than Garrett and Owen would have us believe. (shrink)
