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.

After reconstructing three arguments for Nietzsche’s descriptive analysis of the self as complex, this article clarifies some of greatness’s psychological conditions. It then offers three arguments for why we should not focus on these internal conditions when seeking to verify or to achieve greatness. First, Nietzsche’s descriptive analysis of the self renders introspection too coarse-grained and error-prone to verify the subtle type of unity required for greatness. Second, Nietzsche associates introspective appraisal of one’s psyche with a moral project that weakens (...) and represses the drives, such that inquiry into whether greatness’s internal conditions are satisfied typically speaks against their realization. Finally, the actions characteristic of Nietzsche’s great individuals prohibit introspective preoccupation with oneself. These arguments suggest that we should attend to outwardly directed accomplishments, rather than psychology, when appraising the greatness of others and seeking to become great ourselves. (shrink)

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Paul Sagar's invigorating book is a reconsideration of Adam Smith in the sense that it challenges much that is received wisdom in current scholarship. First and foremost, it rejects the idea that Smith was preeminently a moral philosopher concerned with the threat to civic virtue posed by commercial society, and yet intent on giving commercial society a moral vindication nevertheless. Sagar—rightly, in my view—wants us to recognize Smith as having been a political thinker. Too much work on Smith still assumes (...) that there is not much to say about his political thought because he regarded all but the most minimal government as an obstacle to the proper functioning of markets.

This summary account of Hume’s life and works challenges the usual way of telling the story of Hume’s career. It is generally believed that what Hume most wanted to be was a philosopher and that Hume turned to politics and history because that desire was frustrated, principally by the reputation for atheism he had acquired as a result of his writings on religion. The author argues that, from the beginning, Hume was as interested in politics as he was in philosophy; (...) that a career as an independent man of letters, and not as a professional philosopher, was what he most wanted; and that that career was a success, with the History of England its triumphant culmination. Hume’s religious skepticism was no obstacle to his living the life that he most wanted to live, the life of a sophisticated and widely respected citizen of the European republic of letters. (shrink)

What is the cognitive significance of talking to ourselves? I criticize two interpretations of this function , and offer a third: I argue that inner speech is a genuine dialogue, not a monologue; that the partners in this dialogue represent the independent interests of experienced meaning and logical articulation; that the former is either silent or capable only of abbreviated speech; that articulation is a logical, not a social demand; and that neither partner is a full-time subordinate of the other.

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.

What big questions and large‐scale narratives give coherence to the history of science? From the late 1970s onward, the field has been transformed through a stress on practice and fresh perspectives from gender studies, the sociology of knowledge, and work on a greatly expanded range of practitioners and cultures. Yet these developments, although long overdue and clearly beneficial, have been accompanied by fragmentation and loss of direction. This essay suggests that the narrative frameworks used by historians of science need to (...) come to terms with diversity by understanding science as a form of communication. The centrality of processes of movement, translation, and transmission is already emerging in studies of topics ranging from ethnographic encounters to the history of reading. Not only does this approach offer opportunities for crossing boundaries of nation, period, and discipline that are all too easily taken for granted; it also has the potential for creating a more effective dialogue with other historians and the wider public.

Despite Plato's various warnings not to do so, his dialogues have been studied as systematic philosophy since antiquity. In this innovative and controversial reassessment, James Arieti argues that they should be read primarily as works of drama rather than philosophical discourse. Analyses of 18 of the 28 dialogues allow the reader to see them as integrated dramas, with all the ambiguities and uncertainties that literary works contain. As in plays generally, the arguments of particular characters cannot be seen as (...) the opinions of the author, whose views emerge only from examining each work as a whole. This literary reading shows how much of the debate about Plato's meaning has been misplaced. Instead of demonstrating that an argument is fallacious or valid, we need to ask why Plato has the particular character make the argument. Interpreting Plato achieves what no other work on Plato has attempted: to see the philosophical arguments as serving a dramatic purpose. (shrink)

Abstract:This paper is an analysis of Plato's use of the embassy to Achilles in Homer's Iliad book 9 as a literary template for Crito's mission to persuade Socrates to escape from prison in Athens. Plato's purpose is to elevate the nature of a hero by contrasting the impulsive, impetuous, mercurial temper of Achilles with the steady, thoughtful, deliberative, calmly rational argument of Socrates. Plato shows, in a volley fired at the poet, how the philosopher is more meaningfully heroic than the (...) warrior, for where the warrior aims selfishly at securing his own honor, the philosopher aims at political virtue.

Since its introduction in 1987, Benjamin Freedman’s principle of clinical equipoise has enjoyed widespread uptake in bioethics discourse. Recent years, however, have witnessed a growing consensus that the principle is fundamentally flawed. One of the most vocal critics has undoubtedly been Franklin Miller. In a 2008 paper, Steven Joffe and Miller build on this critical work, offering a new conception of clinical research ethics based on science, taking what they call a “scientific orientation” toward the ethics of clinical research. Though (...) there is much to recommend Joffe and Miller’s scientifically oriented conception of clinical research ethics, I believe that both the critical and constructive projects suffer from the same basic mistake: inattention to context. The internal norms of science cannot be fully specified, let alone satisfied, independently of contextual (external) factors that only come into view when we are attentive to the particular context of that form of inquiry.

(3) A generalization of Revonsuo's “threat simulation” model in reverse is more plausible and is empirically testable. [Hobson et al.; Solms; Revonsuo; Vertes & Eastman].
