Aging is accompanied by changes in general cognitive functioning which may impact the learning rate of older adults; however, this is often not controlled for in cognitive aging studies. We investigated the contribution of differences in learning rates to age-related differences in landmark knowledge acquired from route learning. In Experiment 1 we used a standard learning procedure in which participants received a fixed amount of exposure to a route. Consistent with previous research, we found age-related deficits in associative cue and (...) landmark sequence knowledge. Experiment 2 controlled for differences in learning rates by using a flexible exposure learning procedure. Specifically, participants were trained to a performance criterion during route learning before being tested on the content of their route knowledge. While older adults took longer to learn the route than younger adults, the age-related differences in associative cue knowledge were abolished. The deficit in landmark sequence knowledge, however, remained. Experiment 3 replicated these results and introduced a test situation in which a deficit in landmark sequence knowledge yielded an increased likelihood of disorientation in older adults. The findings of this study suggest that age-related deficits in landmark associative cue knowledge are attenuated by controlling for learning rates. In contrast, landmark sequence knowledge deficits persist and are best explained by changes in the learning strategy of older adults to acquire task essential associative cue knowledge at the expense of supplementary sequence knowledge.

Disorders of volition are often accompanied by, and may even be caused by, disruptions in the phenomenology of agency. Yet the phenomenology of agency is at present little explored. In this paper we attempt to describe the experience of normal agency, in order to uncover its representational content.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

Neurovascular coupling (NVC), the transient regional hyperemia following the evoked neuronal responses, is the basis of blood oxygenation level-dependent techniques and is generally adopted across physiological conditions, including the intrinsic resting state. However, the possibility of neurovascular dissociations across physiological alterations is indicated in the literature. To examine the NVC stability across sleep–wake states, we used electroencephalography (EEG) as the index of neural activity and functional magnetic resonance imaging (fMRI) as the measure of cerebrovascular response. Eight healthy adults were recruited (...) for simultaneous EEG-fMRI recordings in nocturnal sleep. We compared the cross-modality (EEG vs. fMRI) consistency of functional indices (spectral amplitude and functional connectivity) among five states of wakefulness and sleep (state effect). We also segregated the brain into three main partitions (anterior, middle and posterior) for spatial assessments (regional effect). Significant state effects were found on δ, α and fMRI indices and regional effects on the α and fMRI indices. However, the cross-state EEG changes in spectral amplitude and functional connectivity did not consistently match the changes in the fMRI indices across sleep–wake states. In spectral amplitude, the δ band peaked at the N3 stage for all brain regions, while the fMRI fluctuation amplitude peaked at the N2 stage in the central and posterior regions. In regional connectivity, the inter-hemispheric connectivity of the δ band peaked at the N3 stage for all regions, but the bilateral fMRI connectivity showed the state changes in the anterior and central regions. The cross-modality inconsistencies across sleep–wake states provided preliminary evidence that the neurovascular relationship may not change in a linear consistency during NREM sleep. Thus, caution shall be exercised when applying the NVC presumption to investigating sleep/wake transitions, even among healthy young adults. (shrink)

Neural activity varies continually from moment to moment. Such temporal variability (TV) has been highlighted as a functionally specific brain property playing a fundamental role in cognition. We sought to investigate the mechanisms involved in TV changes between two basic behavioral states, namely having the eyes open (EO) or eyes closed (EC) in vivo in humans. To these ends we acquired BOLD fMRI, ASL, and [18F]-fluoro-deoxyglucose PET in a group of healthy participants (n = 15), along with BOLD fMRI and (...) [18F]-flumazenil PET in a separate group (n = 19). Focusing on an EO- vs EC-sensitive region in the occipital cortex (identified in an independent sample), we show that TV is constrained in the EO condition compared to EC. This reduction is correlated with an increase in energy consumption and with regional GABAA receptor density. This suggests that the modulation of TV by behavioral state involves an increase in overall neural activity that is related to an increased effect from GABAergic inhibition in addition to any excitatory changes. These findings contribute to our understanding of the mechanisms underlying activity variability in the human brain and its control. (shrink)

Contemporary epistemology has been moving away from classical foundationalism—the thesis that our empirical knowledge is grounded in perceptual beliefs we know with certainty. McGrew reexamines classical foundationalism and offers a compelling reconstruction and defense of empirical knowledge grounded in perceptual certainty. He articulates and defends a new version of foundationalism and demonstrates how it meets all the standard criticisms. The book offers substantial rebuttals of the arguments of Kuhn and Rorty and demonstrates the value of the classical analytic approach to (...) philosophy. 'Foundations' will interest philosophers of science, language, and the mind. (shrink)

This book holds classical liberalism responsible for an American concept of beauty that centers upon women, wilderness, and machines. For each of the three beauty components, a cultural entrepreneur supremely sensitive to liberalism’s survival agenda is introduced. P.T. Barnum’s exhibition of Jenny Lind is a masterful combination of female elegance and female potency in the subsistence realm. John Muir’s Yosemite Valley is surely exquisite, but only after a rigorous liberal education prepares for its experience. And Harley Earl’s 1955 Chevrolet Bel (...) Air is a dreamy expressionist sculpture, but with a practical 265 cubic inch V-8 underneath. Not that American beauty has been uniformly pragmatic. The 1950s are reconsidered for having temporarily facilitated a relaxation of the liberal survival priorities, and the creations of painter Jackson Pollock and jazz virtuoso Ornette Coleman are evaluated for their resistance to the pressures of pragmatism. The author concludes with a provocative speculation regarding a future liberal habitat where Emerson’s admonition to attach stars to wagons is rescinded. (shrink)

The Uncertainty of Analysis pursues key issues raised in the author's earlier Discourse of Modernism, a ground-breaking work which focused attention on the nature of discourse and the ways in which one culturally dominant "discursive class" may be replaced by another. In this timely and provocative collection of his essays, Timothy J. Reiss shows how efforts to reconfirm the force and power of modernist, analytico-referential discourse in the late nineteenth and the twentieth centuries have actually brought to the fore (...) internal contradictions, have made clear the problematic nature of the dominant discourse, and have precipitated the emergence of competing discourses. Reiss considers the explorations in foundational logic by Frege and Peirce; examinations of language and its relations to mind by Saussure, Greimas, and Chomsky; work in linguistic and scientific epistemology by Wittgenstein and Heisenberg; and the attempts to analyze the nature of society by Sartre and other Western Marxists. Reiss turns to some practitioners of literary criticism and theory who have sought to escape past constraints, and he points to what appear to be erroneous routes away from the dilemmas raised by these philosophers and critics.

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

The target paper by Noë and Thompson is a very welcome addition to the literature on the neural correlates of consciousness. It raises a number of important issues, and the debate it will generate should go some way towards clarifying the conceptual terrain that we’re in. In this commentary I focus on three issues: the link between isomorphism and the matching-content doctrine; the argument against the matching-content doctrine; and the argument against experiential internalism.

New insights into the microbiome, epigenetics, and cognition are radically challenging our very idea of what it means to be 'human', while an explosion of neo-materialist thinking in the humanities has fostered a renewed appreciation of the formative powers of a dynamic material environment.

Bertie Ahern, the incumbent Taoiseach or Prime Minister of Ireland, was elected to a third term in the general election of 24 May 2007. While Ahern's party, Fianna F il, was able to retain its governing coalition, the level of support of some of the other parties changed dramatically. Fine Gael, the principal opposition party, saw its number of seats in the parliament, D il ireann, increase by nineteen. Some of the minor parties did less well than expected or compared (...) to previous elections. Only the Greens maintained their six representatives. As a result, they were rewarded with a share in the new government. This election suggests that, while Irish society is changing rapidly, the political system is changing more slowly and subtly. This article examines the election results in terms of the fate of the political parties and focuses on one constituency, Tipperary South, to illustrate trends in Irish electoral politics. (shrink)

Amine acetylation is a diverse topic with importance to the regulation of several physiological processes as well as the metabolism of drugs and environmental chemicals. Arylalkylamine N‐acetyltransferase is widely distributed in several species, where this enzyme plays an important role in the seasonal regulation of reproduction and photoperiodism in vertebrates through the pathway of melatonin formation. In insects, this enzyme is involved in monoamine neurotransmitter inactivation and the formation of catecholamine intermediates necessary for sclerotization of the insect cuticle.

In lieu of an abstract, here is a brief excerpt of the content:Denying the Body? Memory and the Dilemmas of History in DescartesTimothy J. ReissIn an essay first published in The New York Review of Books in January 1983, touching her apprenticeship as writer, the Barbadian /American novelist Paule Marshall described the long afternoon conversations with which her mother and friends used to relax in the family kitchen. She recalled how they saw things as composed of opposites; not torn, but (...) completed and made whole by them.Theirs was not a Manichean brand of dualism that sees matter, flesh, the body, as inherently evil, because they constantly addressed each other as “soully-gal”—soul: spirit; gal: the body, flesh, the visible self. And it was clear from their tone that they gave one as much weight and importance as the other. They had never heard of the mind/body split. 1This closing claim is surely less than self-evident. Whether or not the companions had heard of the mind/body split depends on the meaning given to the verb “hear.” Certainly it was embedded in their language, however much the phrase “soully-gal” might recombine its parts.Did the split come from Descartes and early European debates, linguistically colonizing all those who came within its sphere—Africans, Barbadians, Brooklynites? Did it come from a Christian heritage, with its haggling over bodily mortality and immortality of soul? Who knows? A first point is that it is still an everyday experience, deeply buried in language and so in the ideas, feelings, and meanings expressed in language. A second point is that the post-Cartesian debates—to simplify for a moment with an overly heavy [End Page 587] hand—were and are themselves but a variant within a much longer received wisdom. Nonetheless, such wisdom is now bound to that variant, which, willy-nilly, does give one set of parameters to a common experience—at least, to that of those of us who dwell under Western hegemonies. It gives them also, no doubt, to many who live within them at once less clearly and more contentiously.I would like to offer a further powerful instance here, simply to emphasize what and how much is at stake in the questions to be addressed. It occurs in a writing by the Guyanese novelist Wilson Harris, his Palace of the Peacock. First in a tetralogy, this novel recounts something like a journey away from a life of colonial and postcolonial violence and oppression towards a hoped-for rebirth in “fulfilment and understanding.” 2 Early on, the harsh protagonist, Donne, mocks the narrator, his mysterious “double” and “brother,” Dreamer, who has remarked their distance from “the folk.” “Is it a mystery of language and address?” asks Donne. Slightly bewildered, Dreamer struggles to suggest that the obstacle is less of language than of a deeper disjunction:“it’s an inapprehension of substance,” I blurted out, “an actual fear of the substance of life, fear of the substance of the folk, a cannibal blind fear in oneself. Put it how you like,” I cried, “it’s a fear of acknowledging the true substance of life. Yes, fear I tell you, the fear that breeds bitterness in our mouth, the haunting sense of fear that poisons us and hangs us and murders us. And somebody,” I declared, “must demonstrate the unity of being, and show...” I had grown violent and emphatic... “that fear is nothing but a dream and an appearance....” 3Recovery of unity might become a way to defeat political and historical violences. In the next novel in the sequence, one of two self-indulgently whining characters, accused of pining for a woman who has run away to seek education, explodes: “I don’t believe you can begin to see how some body like they born seeking for mind.” 4 For peoples of the colonized Americas, imbued with “the great civilization of the American Indian,” this urge, Harris then wrote in a critical essay, was simply the personal form of a social and political necessity to recover still-living elements of a culture for which “matter truly bore the imprint of genius,” refusing “the taboo of spirituality removed from sensuous direction.” 5 Recently, Harris has worried this...

This paper looks at the concept of neighborhood canonicity introduced by BRIAN CHELLAS [2]. We follow the lead of the author's paper [9] where it was shown that every non-iterative logic is neighborhood canonical and here we will show that all logics whose axioms have a simple syntactic form-no intensional operator is in boolean combination with a propositional letter-and which have the finite model property are neighborhood canonical. One consequence of this is that KMcK, the McKinsey logic, is neighborhood canonical, (...) an interesting counterpoint to the results of ROBERT GOLDBLATT and XIAOPING WANG who showed, respectively, that KMcK is not relational canonical [5] and that KMcK is not relationally strongly complete [11].

We discuss three varieties of affective dynamics. In each case, we suggest how these affective dynamics should be operationalized and measured in daily life using time-intensive methods, like ecological momentary assessment or ambulatory assessment, and recommend time-sensitive analyses that take into account not only the variability but also the temporal dependency of reports. Studies that explore how these affective dynamics are associated with psychological disorders and symptoms are reviewed, and we emphasize that these affective processes are within a nexus of (...) other components of emotion regulation.

The dissertation examines Davidson and Heidegger's rejections of correspondence truth, as well as their claims that truth is theoretically primitive. Truth is primitive in the sense that it cannot be reduced to, nor defined in terms of, some other more theoretically basic concepts, such as those offered in correspondence, coherence, and pragmatic accounts of truth. The fact that truth cannot be defined in terms of more basic concepts does not mean that there are not important and meaningful things to say (...) about truth; Davidson and Heidegger's agreement that there is more to say about truth distinguishes them from minimalist approaches to truth. Davidson and Heidegger make explicit truth's conceptual relationship to other important areas of inquiry such as language, subjectivity, and ontology. The dissertation claims that the two philosophers agree, despite radically different background texts and methodologies, on the fundamental relationship between self, other, and world. The dissertation moves beyond mere comparison by showing that Davidson's own position commits him to a Heideggerian treatment of truth, or something like it. I argue that understanding the similarities and supplemental arguments offered by each philosopher leads to a better overall account of truth than that offered by each philosopher individually. Moreover, I argue that although Heidegger and Davidson offer primarily transcendental arguments, their theories can accommodate naturalistic theories of language and concept acquisition. (shrink)

Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the preparation and execution of voluntary actions, as well as its underlying neural activity, are coupled with the breathing cycle. In the current study, we investigated whether such breathing-action coupling is limited to voluntary motor action or whether it is also present for mental actions not involving any overt (...) bodily movement. To answer this question, we recorded electroencephalography (EEG), electromyography (EMG), and respiratory signals while participants were conducting a voluntary action paradigm including self-initiated motor execution (ME), motor imagery (MI), and visual imagery (VI) tasks. We observed that the voluntary initiation of ME, MI, and VI are similarly coupled with the respiration phase. In addition, EEG analysis revealed the existence of readiness potential (RP) waveforms in all three tasks (i.e., ME, MI, VI), as well as a coupling between the RP amplitude and the respiratory phase. Our findings show that the voluntary initiation of both imagined and overt action is coupled with respiration, and further suggest that the breathing system is involved in preparatory processes of voluntary action by contributing to the temporal decision of when to initiate the action plan, regardless of whether this culminates in overt movements. -/- .

In this paper I critically examine the implications of the uncodifiability thesis for principlism as a pluralistic and non-absolute generalist ethical theory. In this regard, I begin with a brief overview of W.D. Ross’s ethical theory and his focus on general but defeasible prima facie principles before turning to 2) the revival of principlism in contemporary bioethics through the influential work of Tom Beauchamp and James Childress; 3) the widespread adoption of specification as a response to the indeterminacy of abstract (...) general principles and the limitations of balancing and deductive approaches; 4) the challenges raised to fully specified principlism by the uncodifiability thesis and 5) finally offer a defense of the uncodifiability thesis against various critiques that have been raised.

Solon's extraordinary claim, that we should call "no one happy who is still living", presents a fascinating and distinctive argument about happiness and the length of a human life. The issues Solon raises are important, and even if we think his pessimistic conclusion is an exaggeration we can still appreciate his central concern how conceptions of happiness and the length of a human life are connected. The purpose of this paper is to explore a few of these problems, in particular (...) the reason why Aristotle's reply to Solon in the Nicomachean Ethics is somewhat ambiguous. We find Aristotle addressing Solon's claim at the outset of Eth. Nic. A 10, troubled in one sense by its conclusion, yet struck by its partial truth. On the one hand, he thinks that requires a "complete life" or at the very least, a sufficient and "complete span of time", both of which are compatible with Solon's advice that we should postpone calling someone happy until a later point in life. But on the other hand Aristotle defines in such a way that raises the question whether he needs to accept Solon's claim in any form. In particular, if happiness is defined in terms of excellent activity as Aristotle repeatedly claims, why should we wait until a person dies to call him or her happy? Why shouldn't excellent actions, at the very time they are performed, count someone as happy? The puzzle, in short, is the fact that Aristotle defines happiness in terms of activities that are complete without developing over time, and yet also claims that happiness requires a "complete lifetime".

ABSTRACT:Drawing upon the collective action model of institutional change, I reconceptualize moral imagination as both a social process and a cognitive one. I argue that moral outcomes are not produced by individual actors alone; rather, they emerge from collective action processes that are influenced by political conditions and involve behaviors that include issue framing and resource mobilization. I also contend that individual moral imagination involves the integration of moral sensitivity with consideration of collective action dynamics. I illustrate my arguments with (...) a case study of the Chad-Cameroon oil project. The paper suggests new directions in teaching and research on moral imagination. (shrink)
