Fodor argues that speech perception is accomplished by a module. Typically, modular processing is taken to be bottom-up processing. Yet there is ubiquitous empirical evidence that speech perception is influenced by top-down processing. Fodor attempts to resolve this conflict by denying that modular processing must be exclusively bottom-up. It is argued, however, that Fodor's attempt to reconcile top-down and modular processing fails, because: (i) it undermines Fodor's own conception of modular processing; and (ii) it cannot account for the contextually varying (...) top-down influences that characterize speech perception.

The overall goal of speech perception research is to explain how spoken language is recognized and understood. In the current research framework it is assumed that the key to achieving this overall goal is to solve the lack of invariance problem. But nearly half a century of sustained effort in a variety of theoretical perspectives has failed to solve this problem. Indeed, not only has the problem not been solved, virtually no empirical candidates for solving the problem have been produced. (...) One explanation for this lack of progress is simply that no theory has yet hit upon the correct set of invariant properties. Another explanation is that the goal of solving the lack of invariance problem is itself misguided. The most basic claim of this dissertation is that the latter explanation is correct. ;The lack of progress in explaining speech perception exhibited by the current research framework, I argue, is not, in the first instance, due to the failure of individual theories to solve the lack of invariance problem, but rather to the common background assumption that doing so is in fact the key to explaining speech perception. ;My overall argument in support of this basic claim has three main components: criticism of the empirical results of research in the current framework; criticism of the formulation of theories generated in the current research framework; and the availability of an alternative account of phonetic structure. ;The heart of my argument is an analysis of the character of the theoretical weaknesses of three theories of speech perception: the motor theory of speech perception, the ecological theory of speech perception, and the theory of acoustic invariance. I show that, in each case, the particular theoretical problems result from trying to satisfy the common goal of identifying invariant properties of phonetic percepts. ;I analyze the methodological error embodied in the current approach to explaining speech perception as, in general, one of abstracting the wrong kinds of properties from the detail of the speech event, and, in particular, of abstracting away from dynamic and context-dependent properties.

In this paper I provide a metatheoretical analysis of speech perception research. I argue that the central turning point in the history of speech perception research has not been well understood. While it is widely thought to mark a decisive break with what I call "the alphabetic conception of speech," I argue that it instead marks the entrenchment of this conception of speech. In addition, I argue that the alphabetic conception of speech continues to underwrite speech perception research today and (...) moreover that it functions as a dogma which ought to be rejected.

The suggestion that analytic isomorphism should be rejected applies especially to the domain of speech perception because (1) the guiding assumption that solving the lack of invariance problem is the key to explaining speech perception is a form of analytic isomorphism, and (2) after nearly half a century of research there is virtually no empirical evidence of isomorphism between perceptual experience and lower-level processing units.

Norris, McQueen & Cutler claim that all known speech recognition data can be accounted for with their autonomous model, “Merge.” But this claim is doubly misleading. (1) Although speech recognition is autonomous in their view, the Merge model is not. (2) The body of data which the Merge model accounts for, is not, in their view, speech recognition data.

Imagine walking into Starbuck's, ordering a double latte, meeting a friend, drinking up, and leaving. In the course of this simple event, you would engage in a wide variety of cognitive activities, among them problem solving, face recognition, speech production and perception, memory, and motor control. How does the mind – an apparently unitary entity – accomplish such a diversity of tasks? Is the mind partitioned into diverse mechanisms, each responsible for a different job? Or are more uniform, general‐purpose mechanisms (...) deployed for different cognitive purposes? Which tasks even count as the same, and which as different? Is visual recognition a single task, or are the mechanisms that recognize objects fundamentally distinct from those that recognize faces? Is speech produced and perceived by similar processes or by different ones? More generally, how, and how much, do such different processes interact? (shrink)

. Björn Lindbloms account of the emergence of phonemic structure is a central reference point in contemporary discussions of the emergence of language. I argue that there are two distinct, and largely orthogonal conceptions of emergence implicit in Lindbloms account. According to one conception (causal emergence), the process by which minimal pairs are generated is crucial to the claim that phonemic structure is emergent; according to the other conception (analytic emergence), the fact that segments are an abstraction from the physical (...) signal is what is crucial to the description of phonemic structure as emergent. The purpose of distinguishing rather than conflating these two conceptions of emergence is not in the first instance to criticize Lindbloms account or to force us to choose between the two conceptions for consistency, but rather to give us a more detailed purchase on the notoriously thorny concept of emergent explanation.

Drawing on feminist philosophical accounts of reproduction and initial data acquired through research with migrant mothers in London, this article argues that the role and place of reproduction remains under-theorized within scholarly accounts of women's role in migration processes. Working with an expanded concept of reproduction that includes not only childbirth and motherhood, but also the work of reproducing heritage, culture and structures of belonging, it argues that feminist migration scholars can draw on valuable theoretical resources in order to tell (...) more complicated stories about the place of reproduction in migration, and challenge the often problematic gendered distinctions between travelling and staying put, change and repetition that continue to underpin some of the narrative structures operative in migration studies.

The commentaries on the Ethica nova and the Ethica vetus written by some masters of the arts – presumably operating in the Paris faculty – in the first half of the thirteenth century expound in an original way the doctrine of the virtutes consuetudinales which Aristotle, at the end of the first book of his Ethica (I 13), distinguishes into the two main classes of the “moral virtues” and the “intellectual virtues”. The present paper aims at highlighting the particularly important (...) task which is assigned to the intellectual virtues in these early commentaries: joining man to God directly, through a contemplation which becomes love. The masters of the arts maintain that the moral virtues, in spite of the definition given by Aristotle (habitus a quo quis bonus est et opus eius bene reddit), are not sufficient alone to bring man to perfection, but that other more perfect virtues, namely the intellectual ones, are needed in order to make him know and love the supreme good. Having no knowledge of the sixth book of the Ethica, in which Aristotle deals in particular with the intellectual virtues, our masters know only their general description and are concerned with clarifying their relationships with the moral virtues, compared to which they appear to be sometimes really distinct and sometimes united to them in sharing the recta ratio, so much that they may constitute a double virtue. Although the masters of the arts seem to be well-informed about the teaching of the theologians – which they often cite without opposing to it, albeit stressing their own philosophical point of view –, it is significant that no reference whatsoever is made by them to the theological virtues and that they have recourse to the themes of Avicennian mysticism such as the doctrine of the two faces of the soul. Besides presenting the commentaries on the Ethica vetus from a general point of view, I will focus on the Paris commentary in Ethicam veterem (Paris BN lat. 3804A, ff. 152ra-159vb, 241ra-247vb; Paris BN lat. 3572, ff. 226ra-235ra), of which I am preparing a critical edition. The Paris commentary contains in fact a special and original discussion of the doctrine of the virtutes intellectuales. (shrink)

Theory of Mind is the ability to predict and understand the mental state of another. While ToM is theorized to play a role in language, we examined whether such a mentalizing ability plays an important role in establishing shared understanding in conversation. Pairs of participants engaged in a Lego model building task in which adirectorinstructed abuilderon how to create duplicate models from a prototype that only the director could see. We manipulated whether the director could see or could not see (...) the builder’s workspace. As predicted, the Mind in the Eyes test predicted accuracy when the workspace was hidden. A high mentalizing ability was an advantage when instructing, resulting in fewer errors, but may be a disadvantage when following instructions. This research indicates that ToM plays a key role in communicating information effectively in conversation. (shrink)

There are several conceptions of truth, such as the classical correspondence conception, the coherence conception and the pragmatic conception. The classical correspondence conception, or Aristotelian conception, received a mathematical treatment in the hands of Tarski (cf. Tarski [1935] and [1944]), which was the starting point of a great progress in logic and in mathematics. In effect, Tarski's semantic ideas, especially his semantic characterization of truth, have exerted a major influence on various disciplines, besides logic and mathematics; for instance, linguistics, the (...) philosophy of science, and the theory of knowledge. The importance of the Tarskian investigations derives, among other things, from the fact that they constitute a mathematical, formal mark to serve as a reference for the philosophical (informal) conceptions of truth. Today the philosopher knows that the classical conception can be developed and that it is free from paradoxes and other difficulties, if certain precautions are taken. We believe that is not an exaggeration if we assert that Tarski's theory should be considered as one of the greatest accomplishments of logic and mathematics of our time, an accomplishment which is also of extraordinary relevance to philosophy, as we have already remarked. In this paper we show that the pragmatic conception of truth, at least in one of its possible interpretations, has also a mathematical formulation, similar in spirit to that given by Tarski to the classical correspondence conception.

This essay is a critical review of two recent collections, Feminism and Foucault: Reflections on Resistance, edited by Irene Diamond and Lee Quinby and Feminism as Critique: On the Politics of Gender, edited by Seyla Benhabib and Drucilla Cornell. While the collections differ in their manner of addressing the critical sources that have inspired them-the former relying upon a single theorist, the latter attempting to move through some of the philosophical history that constitutes our present theoretical terrain-both attempt to (...) think through and thus revisualize some of the categories of difference which we have inherited. Though the best essays from these collections are celebrated for demonstrating how "feminism as critique" can work to move us toward a clearer and more inclusive feminist theory, questions are raised about what the inattention to race in these volumes suggests about our own role in the construction of power and knowledge, and the erasures that help to secure them both.

‘‘Post-normal science’’ has received much attention in recent years, but like many iconic concepts, it has attracted differing conceptualizations, applications, and implications, ranging from being a ‘‘cure-all’’ for democratic deficit to the key to achieving more sustainable futures. This editorial article introduces a Special Issue that takes stock of research on PNS and critically explores how such research may develop. Through reviewing the history and evolution of PNS, the authors seek to clarify the extant definitions, conceptualizations, and uses of PNS. (...) The authors identify five broad areas of research on, or using, PNS which have developed over four decades. Their analysis suggests that the 1990s represent a symbolic watershed in the use of PNS terminology, when the concept was further developed and applied to highly complicated issues such as climate change. The authors particularly distinguish between uses of PNS as a normative prescription and as a practical method. Through this classification, they set out gaps and research questions arising. They then briefly summarize the Special Issue articles and consider their relationship to each other and the research questions raised by their analysis. They conclude by considering what the articles in this issue suggest for future theory building in PNS and related scholarship. (shrink)

By putting existential phenomenology into conversation with virtue ethics, this book offers a new interpretation of human flourishing. It rejects characterizations of flourishing as either a private subjective state or an objective worldly status, arguing that flourishing is rather a successfully negotiated self-world fit – a condition involving both the essential dependence of the self upon the world and others, and the lived normative responsiveness of the agent striving to be in the world well. A central argument of the book (...) is that there is an irreducible normative plurality arising from the different practical perspectives we can adopt – the first, second, and third-person stances – all of which make different kinds of normative claim that we understand ourselves as having reason to meet. Flourishing is human excellence within each of these normative domains achieved in such a way that success in one domain does not compromise success in another. Existential Flourishing provides a correspondingly transformed interpretation of the virtues as solutions to various existential problems we face in responding to these normative domains. The book also addresses traditional problems in virtue ethics and analyzes the structure of four virtues in detail: justice, patience, modesty, and courage. (shrink)

The “nature” of an artifact is often equated with its function. Clearly, an artifactual function must be an extrinsic property. This feature of functions has important implications on the semantics of artifactual kind terms: it enables us to vindicate that artifactual kind terms have an externalist semantics. Any alleged externalist theory, indeed, must show that the referents of the considered terms share a common nature (i.e., an extrinsic property), whether we know or could possibly ever know what that nature is. (...) However, the state of the art shows that function is not enough to represent such “nature”: function does not exhaustively account for important phenomena that characterize artifacts and artifactual kinds, nor does it thoroughly define what they are. Thus, extending the scope of externalism to artifactual kind terms seems doomed to fail. Pace opposite views, it could even be argued that artifacts are a sub-class of social kinds. If so, not only social but also artifactual kind terms cannot refer externalistically, since their referents constitutively depend on human intentions and norms. Either way, externalism fails to apply to those kinds of terms. (shrink)

This paper explores whether MacIntyrean virtue ethics concepts are applicable in non-Western business contexts, specifically in SMEs in Taiwan, a country strongly influenced by the Confucian tradition. It also explores what differences exist between different polities in this respect, and specifically interprets observed differences between the Taiwanese study and previous studies conducted in Europe and Asia. Based on case study research, the findings support the generalizability of the MacIntyrean framework. Drawing on the institutional logics perspective and synthesizing this with MacIntyrean (...) concepts, the paper explains the differences between the studies largely by reference to the Confucian tradition operating at both the micro-level within firms and at the macro-level as a means of harmonizing the potentially competing institutional logics to which firms are subject. The recent weakening of this tradition, however, suggests that increased conflict may characterize the future. (shrink)

Known throughout East Asia as Mengzi, or "Master Meng," Mencius was a Chinese philosopher of the late Zhou dynasty, an instrumental figure in the spread of the Confucian tradition, and a brilliant illuminator of its ideas. Mencius was active during the Warring States Period, in which competing powers sought to control the declining Zhou empire. Like Confucius, Mencius journeyed to one feudal court after another, searching for a proper lord who could put his teachings into practice. Only a leader who (...) possessed the moral qualities of a true king could unify China, Mencius believed, and in his defense of Zhou rule and Confucian philosophy, he developed an innovative and highly nuanced approach to understanding politics, self-cultivation, and human nature, profoundly influencing the course of Confucian thought and East Asian culture. _Mencius_ is a record of the philosopher's conversations with warring lords, disciples, and adversaries of the Way, as well as a collection of pronouncements on government, human nature, and a variety of other philosophical and political subjects. Mencius is largely concerned with the motivations of human actors and their capacity for mutual respect. He builds on the Confucian idea of _ren_, or humaneness, and places it alongside the complementary principle of _yi_, or rightness, advancing a complex notion of what is right for certain individuals as they perform distinct roles in specific situations. Consequently, Mencius's impact was felt not only in the thought of the intellectual and social elite but also in the value and belief systems of all Chinese people. (shrink)

Recent studies indicate that patients who are diagnosed with vegetative states may retain more awareness than their clinical assessments suggest. Disorders of consciousness traditionally have been diagnosed on the basis of outwardly observable behaviors alone, but new functional imaging studies have shown surprising levels of brain activity in some patients, indicating that even higher-level cognitive functions like language processing and visual imagery may be preserved. For example, one recently developed method purports to detect voluntary mental imagery solely on the basis (...) of neural response patterns observed with functional magnetic resonance imaging. This line of research has already led to some widely reported cases of patients who were discovered to have more brain activity than expected. In November 2009, Rom Houben, a Belgian man who was thought to be in a coma for 23 years, was diagnosed with locked-in syndrome through the use of neuroimaging; however, that assessment was later overturned by further testing.

Background The aim was to explore how the clinical ethics committees in Norway have worked and functioned within mental health care and addiction treatment services. Methods Analysis of 256 annual reports from clinical ethics committees from 2003 to 2012 and a survey to clinicians who had used a clinical ethics committee. Results Dilemmas related to coercion, confidentiality, information, and patient autonomy dominated. The committees established only for psychiatric hospitals, had received more cases from mental health and addiction services than the (...) committees also serving somatic services. Many of the case discussions involved both somatic and mental health care, complicated legal issues as well as ethical dilemmas. Mental health care professionals that have used the clinical ethics committees evaluated the clinical ethics committees deliberation as useful. Conclusion Given the many difficult ethical dilemmas in mental health care ethics work need to be strengthened. The complexity of the cases requires varied and interdisciplinary competence and training among the clinical ethics committee members. (shrink)

Research from behavioural sciences shows that people reach decisions in a much less rational and well-considered way than was often assumed. The doctrine of informed consent, which is an important ethical principle and legal requirement in medical practice, is being challenged by these insights into decision-making and real-world choice behaviour. This article discusses the implications of recent insights of research on decision-making behaviour for the informed consent doctrine. It concludes that there is a significant tension between the often non-rational choice (...) behaviour and the traditional theory of informed consent. Responsible ways of dealing with or solving these problems are considered. To this end, patient decisions aids are discussed as suitable interventions to support autonomous decision-making. However, current PDAs demand certain improvements in order to protect and promote autonomous decision-making. Based on a conception of autonomy, we will argue which type of improvements are needed.

In this paper, we review recent neuroimaging investigations of disorders of consciousness and different disciplines' understanding of consciousness itself. We consider potential tests of consciousness, their legal significance, and how they map onto broader themes in U.S. statutory law pertaining to advance directives and surrogate decision-making. In the process, we outline a taxonomy of themes to illustrate and clarify the variance in state-law definitions of consciousness. Finally, we discuss broader scientific, ethical, and legal issues associated with the advent of neuroimaging (...) for disorders of consciousness and conclude with policy recommendations that could help to mitigate confusion in this realm.

With the turning of wilderness areas into wildlife parks and the returning of developed areas of land to the forces of nature, intermediate hybrid realms surface in which wild and managed nature become increasingly entangled. A partitioning of environmental philosophy into ecoethics and animal welfare ethics leaves these mixed territories relatively uncharted—the first dealing with wild (animals), the second with the welfare of captive or domestic animals. In this article, we explore an environmental philosophy that considers explicitly these mixed situations. (...) We examine a recent Dutch policy of introducing domesticated and semi-wild large herbivores in newly developed nature areas. Larger issues are at stake, such as the intertwinement of nature and culture, the dynamic character of de-domestication processes, and the relation between concepts of authenticity and the wild. We sketch a pluralistic, dynamic, and pragmatic environmental philosophy that is capable of dealing with the complicated ethicalproblems concerning creatures and land caught between domestication and the wild.

The United States’ ambitious Precision Medicine Initiative proposes to accelerate exponentially the adoption of precision medicine, an approach to health care that tailors disease diagnosis, treatment, and prevention to individual variability in genes, environment, and lifestyle. It aims to achieve this by creating a cohort of volunteers for precision medicine research, accelerating biomedical research innovation, and adopting policies geared toward patients’ empowerment. As strategies to implement the PMI are formulated, critical consideration of the initiative's ethical and sociopolitical dimensions is needed. (...) Drawing on scholarship of nationalism and democracy, we discuss the PMI's construction of what we term “genomic citizenship”; the possible normative obligations arising therefrom; and the ethical, legal, and social challenges that will ensue. Although the PMI is a work in progress, discussion of the existing and emerging issues can facilitate the development of policies, structures, and procedures that can maximize the initiative's ability to produce equitable and socially sensitive outcomes. Our analysis can also be applied to other population-based, precision medicine research programs. (shrink)

SCHOFIELD I, TOLSON D and FLEMING V. Nursing Inquiry 2012; 19: 165–176 [Epub ahead of print]How nurses understand and care for older people with delirium in the acute hospital: a Critical Discourse AnalysisDelirium is a common presentation of deteriorating health in older people. It is potentially deleterious in terms of patient experience and clinical outcomes. Much of what is known about delirium is through positivist research, which forms the evidence base for disease‐based classification systems and clinical guidelines. There is little (...) systematic study of nurses’ day‐to‐day practice of nursing patients with delirium. The aim was to uncover the kinds of knowledge that informs nurses’ care and to explicate the basis of that knowledge. Critical Discourse Analysis is underpinned by the premise that powerful interests within society mediate how social practices are constructed. Links were made between the grammatical and lexical features of nurses’ language about care in interviews and naturalistic settings, and the healthcare context. Care focused on the continuous surveillance of patients with delirium by nurses themselves or vicariously through other patients, and containment. Nurses influenced by major discourses of risk reduction and safety, constructed patients with delirium as risk objects. The philosophy of person‐centred and dignified care advocated in nursing literature and government policy is an emerging discourse, though little evident in the data. The current dominant discourses on safety must give space to discourses of dignity and compassion. (shrink)

In this consensus report by a diverse group of academics who conduct and/or are concerned about social and behavioral genomics (SBG) research, the authors recount the often‐ugly history of scientific attempts to understand the genetic contributions to human behaviors and social outcomes. They then describe what the current science—including genomewide association studies and polygenic indexes—can and cannot tell us, as well as its risks and potential benefits. They conclude with a discussion of responsible behavior in the context of SBG research. (...) SBG research that compares individuals within a group according to a “sensitive” phenotype requires extra attention to responsible conduct and to responsible communication about the research and its findings. SBG research (1) on sensitive phenotypes that (2) compares two or more groups defined by (a) race, (b) ethnicity, or (c) genetic ancestry (where genetic ancestry could easily be misunderstood as race or ethnicity) requires a compelling justification to be conducted, funded, or published. All authors agree that this justification at least requires a convincing argument that a study's design could yield scientifically valid results; some authors would additionally require the study to have a socially favorable risk‐benefit profile.

Unrealistic optimism is a bias that leads people to believe, with respect to a specific event or hazard, that they are more likely to experience positive outcomes and/or less likely to experience negative outcomes than similar others. The phenomenon has been seen in a range of health-related contexts—including when prospective participants are presented with the risks and benefits of participating in a clinical trial. In order to test for the prevalence of unrealistic optimism among participants of early-phase oncology trials, we (...) conducted a survey with patients over 18 years of age who were enrolled in a phase I, phase I/II, or phase II clinical cancer trial in the New York City area between August 2008 and October 2009. Participants in our study were asked to compare their own chances of experiencing a range of risks and benefits related to the trial they were enrolled in with the chances of the other trial participants. We found a significant optimistic bias in their responses. Respondents tended to overestimate the benefits of the trial they were enrolled in and underestimate its risks. In addition, we found no significant relationship between respondents’ understanding of the trial’s purpose and how susceptible they were to unrealistic optimism. Our findings suggest that improving the consent process for oncology studies requires more than addressing deficits in understanding. (shrink)

This article uses a conversation analytic framework to describe a type of wh-question used to challenge a prior utterance, specifically to challenge the basis for or right to do an action done by the prior utterance. These wh-questions are able to do challenging because, rather than asking for new information, they are used to convey a strong epistemic stance of the questioner, a negative assertion. The utterances are designed as requests for an account for a prior claim or action, but (...) by conveying a negative assertion, they suggest that there is no adequate account available and, thus, that there are no grounds for the prior claim or action. The use of these questions in institutional settings can display participants' orientation to institutional goals, norms and roles, showing that institutional roles can thus be enacted, and goals accomplished, by means of practices of talk which are not, themselves, institutionally specific.
