The maxillofacial zone is a common site of traumatic injury, which has a direct impact on the aesthetics and function of the patient's face. The mandible is the main structural skeletal bone associated with the face, and the maxillofacial area is a common site of injury. Mandibular fractures have a significant impact on masticatory function. The main cause could also be the patient's ability to chew vigorously until the strength is below normal. This is related to dental comfort and mental (...) attitude. Treatment consisting of surgery along the length of the mandibular fracture, focuses on restoring the structural shape of the mandible, with the hope of restoring normal form and function. Writing purpose systematic review (SR ) for studied further regarding the improvement of masticatory muscle function in mandibular fracture patients after open reduction internal fixation (ORIF).

Nine articles journal Which identified four (4) prospective articles, one (1) retrospective, one (1) cross sectional, one (1) systematic review, one (1) case report, and one (1) case control. Of the ten journal articles that have been reviewed, there are articles, all of which measure masticatory muscle function as an indicator of the success of open reduction procedures. fixation (ORIF). It's just that there are various research specifications that vary, both in terms of the age of the research subjects, part of the injury, method, type of action, data analysis and other indicators that need to be considered in each study. There is an increase in masticatory muscle function in mandibular fracture patients after open reduction internal fixation (ORIF). (shrink)

In this paper I examine the debate between ‘protectionists’ and ‘liberationists’ concerning the appropriate role of minors in decision-making about their health care, focusing particularly on disagreements between the two sides regarding adolescents. Protectionists advocate a more traditional, paternalistic approach in which minors have relatively little input into the healthcare decision-making process, and decisions are made for them by parents or other adults, guided by a commitment to the patient's best interests. Liberationists, on the other hand, argue in favour of (...) expanded participation by minors in treatment decisions, and decision-making authority for at least some adolescents. My examination of the debate includes discussion of liberationist shifts that have taken place in the medical community as well as in legal policy and practice, and consideration of recent research on adolescent development. In the final section of the paper, I propose a moderate position that addresses both liberationist and protectionist concerns. (shrink)

Aesthetics and Music is a rich and interesting study. Hamilton's approach is innovative. He interleaves chapters on the history of philosophical thought about music with more theoretical discussions of music, sound, rhythm and improvisation, but does not cover the work–performance relation, depiction or expression. He draws on an atypically broad range of examples, including avant-garde, medieval, non-Western and jazz. The assumptions are humanist: ‘I wish to argue for an aesthetic conception of music as an art … according to which music (...) is a human activity grounded in the body and bodily movement and interfused with human life’.The historical chapters are valuable and not without analysis and criticism. Hamilton shows how the ancient Greek theorists were more interested in music's mathematical properties as reflecting the underlying harmony of relations between cosmic bodies than in the practice of musicians. While they equated the value of art with its contribution to an education for citizenship and while their concept of the arts differed …. (shrink)

In Supersizing the Mind, Andy Clark argues that the human mind is not bound inside the head but extends into body and environment.

How should we characterize the functional role of conscious visual experience? In particular, how do the conscious contents of visual experience guide, bear upon, or otherwise inform our ongoing motor activities? According to an intuitive and philosophically influential conception, the links are often quite direct. The contents of conscious visual experience, according to this conception, are typically active in the control and guidance of our fine-tuned, real-time engagements with the surrounding three-dimensional world. But this idea is hostage to empirical fortune. (...) It is a hostage, moreover, whose safety is in serious doubt. Thus Milner and Goodale argue for a deep and abiding dissociation between the contents of conscious seeing, on the one hand, and the resources used for the on-line guidance of visuo-motor action, on the other. This ‘dual visual systems’ hypothesis, which finds many echoes in various other bodies of cognitive scientific research, poses a prima facie challenge to the Assumption of Experience-Based Control. More importantly, it provides fuel for an alternative and philosophically suggestive account of the functional role of conscious visual experience. (shrink)

We show that a popular class of connectionist models (which we label 'first order connectionism') looks unlikely to provide the kind of resources required by the hypothesis. We examine some alternative hybrid models that seem more promising. Finally, we raise a more purely philosophical issue concerning the conditions under which a being can count as a genuine believer or cognizer.".

Subjects with delusions profess to believe some extremely peculiar things. Patients with Capgras delusion sincerely assert that, for example, their spouses have been replaced by impostors. Patients with Cotard’s delusion sincerely assert that they are dead. Many philosophers and psychologists are hesitant to say that delusional subjects genuinely believe the contents of their delusions.2 One way to reinterpret delusional subjects is to say that we’ve misidentified the content of the problematic belief. So for example, rather than believing that his wife (...) is has been replaced by an impostor, we might say that the victim of Capgras delusion believes that it is, in some respects, as if his wife has been replaced by an impostor. Another is to say that we’ve misidentified the attitude that the delusional subject bears to the content of their delusion. So for example, Gregory Currie and co-authors have suggested that rather than believing that his wife has been replaced by an impostor, we should say that the victim of Capgras delusion merely imagines that his wife has been replaced by an impostor.3.

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

This article discusses how research on the image-based analysis of facial images has informed this debate by demonstrating that a single representational system for facial identity and facial expression is not only computationally viable, but can simulate existing cognitive data demonstrating apparent dissociable processing of these two facial properties. It discusses the increasing number of cognitive studies that provide support for this view. Neuropsychological case studies of brain-injured patients and provide limited evidence for separate visual routes processing facial identity and (...) facial expression. It deals with neuroimaging studies addressing both facial identity and facial expression processing which shows that the fusiform gyrus contributes to the recognition of both facial properties. Research continues to reinforce the proposal that a common visual framework supports the representation of at least some aspects of facial identity and facial expression. (shrink)

I argue against Schroeder's explanation of pragmatic encroachment on knowledge. In section 1, I introduce pragmatic encroachment and point out that an explanation of it should avoid Pascalian considerations. In section 2, summarize the key aspects of Schroeder's explanation of pragmatic encroachment. In section 3, I argue that Schroeder's explanation faces a dilemma: it either allows for an objectionable form of Pascalian encroachment or it fails to be a fully general explanation of pragmatic encroachment.

Mind, it is increasingly fashionable to assert, is an intrinsically embodied and environmentally embedded phenomenon. But there is a potential tension between two strands of thought prominent in this recent literature. One of those strands depicts the body as special, and the fine details of a creature’s embodiment as a major constraint on the nature of its mind: a kind of new-wave body-centrism. The other depicts the body as just one element in a kind of equal-partners dance between brain, body (...) and world, with the nature of the mind fixed by the overall balance thus achieved: a kind of extended functionalism (now with an even broader canvas for multiple realizability than ever before). The present paper displays the tension, scouts the space of possible responses, and ends by attempting to specify what the body actually needs to be, given its complex role in these recent debates.

I will argue for a novel variant of the knowledge norm for practical reasoning. In Sect. 2, I will look at current variations of a knowledge norm for practical reasoning and I will provide reasons to doubt these proposals. In Sects. 3 and 4, I develop my own proposal according to which knowledge is the norm of apt practical reasoning. Section 5 considers objections. Finally, Sect. 6 concerns the normativity of my proposed knowledge norm and its significance.

In this book, Andy Mueller examines the ways in which epistemic and practical rationality are intertwined. In the first part, he presents an overview of the contemporary debates about epistemic norms for practical reasoning, and defends the thesis that epistemic rationality can make one practically irrational. Mueller proposes a contextualist account of epistemic norms for practical reasoning and introduces novel epistemic norms pertaining to ends and hope. In the second part Mueller considers current approaches to pragmatic encroachment in epistemology, ultimately (...) arguing in favor of a new principle-based argument for pragmatic encroachment. While the book defends tenets of the knowledge-first programme, one of its main conclusions is thoroughly pragmatist: in an important sense, the practical has primacy over the epistemic. (shrink)

Ranging across both standard philosophical territory and the landscape of cutting-edge cognitive science, Mindware: An Introduction to the Philosophy of Cognitive Science, Second Edition, is a vivid and engaging introduction to key issues, research, and opportunities in the field.Starting with the vision of mindware as software and debates between realists, instrumentalists, and eliminativists, Andy Clark takes students on a no-holds-barred journey through connectionism, dynamical systems, and real-world robotics before moving on to the frontiers of cognitive technologies, enactivism, predictive coding, and (...) the extended mind. Throughout, he highlights challenging issues in an effort to engage students in active debate. Each chapter opens with a brief sketch of a major research tradition or perspective, followed by concise critical discussions dealing with key topics and problems. (shrink)

Health care institutions must decide whether to inform the patient of a medical error. The barriers to disclosure are an aversion to admitting errors, a concern about implicating other practitioners, and a fear of lawsuits and liability. However, admission of medical errors is the ethical thing to do and may be required by law. When examined, the barriers to such disclosures have little merit, and, in fact, lawsuits and liability may actually be reduced by informing the patient of medical errors. (...) Therefore, a health care institution should implement a written policy providing for disclosure of medical errors, using a process such as that outlined in the article. (shrink)

Idioms – expressions like kick the bucket and let the cat out of the bag – are strange. They behave in ways that ordinary multi-word expressions do not. One distinctive and troublesome feature of idioms is their unpredictability: The meanings of sentences in which idiomatic phrases occur are not the ones that we would get by applying the usual compositional rules to the usual meanings of their (apparent) constituents. This sort of behavior requires an explanation. I will argue that the (...) right explanation is that the sentences are being interpreted through a pretense. (What this means, exactly, will be explained in what follows.) This is a surprising claim, for two reasons. On the one hand, it seems that adopting a pretense account is overkill—it’s a far more radical move than is required to account for the phenomena. On the other hand, it seems that a pretense account is hopeless—that there is a fatal overgeneration problem for pretense accounts of idiom that causes them to fail, as Jason Stanley charges, “as badly as it is possible for an account of idiom to fail.” So I will have some work to do.

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

Bobier argued that hope is necessary for practical deliberation. I will demonstrate that Bobier’s argument for this thesis fails. The problem is that one of its main premisses rests on a sufficient condition for hoping that is subject to counterexamples. I consider two ways to save the argument, but show that they are unsuccessful in doing so.

Biological brains are increasingly cast as ‘prediction machines’: evolved organs whose core operating principle is to learn about the world by trying to predict their own patterns of sensory stimulation. This, some argue, should lead us to embrace a brain-bound ‘neurocentric’ vision of the mind. The mind, such views suggest, consists entirely in the skull-bound activity of the predictive brain. In this paper I reject the inference from predictive brains to skull-bound minds. Predictive brains, I hope to show, can be (...) apt participants in larger cognitive circuits. The path is thus cleared for a new synthesis in which predictive brains act as entry-points for ‘extended minds’, and embodiment and action contribute constitutively to knowing contact with the world.

My understanding is that proximate explanations concern adaptive mechanism and that ultimate explanations concern adaptive rationale. Viewed in this light, the two kinds of explanation are quite distinct, but they interact in a complementary way to give a full understanding of biological adaptations. In contrast, Laland et al. (2013)—following a literal reading of Mayr (Science 134:1501–1506, 1961)—have characterized ultimate explanations as concerning any and all mechanisms that have operated over the course of an organism’s evolutionary history. This has unfortunate consequences, (...) such as allowing random drift to form the basis for ultimate explanations, and allowing proximate and ultimate explanations to bleed into each other until their distinction is meaningless. Here, I suggest Laland et al’s explanatory framework of “reciprocal causation” is not conducive to successful biological science, and that they have misunderstood key elements of the theory of Darwinian adaptation.

Introduction Jamie Allen Time, of all the dimensions readily presented to experience, seems to do so most readily through things. Stuff, in supposed counter-valence to the negentropic resilience of living things, appears to us as that which degrades through time, and demarcates a more technical chronometry of sequential events. Situated outside the rotting of fruit and the ticking of clocks, a “deep time” persists. Like the ultra-hearing of the bat, and the infra-vision of the boa-constrictor, there exist living and non-living (...) agents and entities capable of revealing the fixity and finitude of our own perceptual frames for thinking and understanding. The recordings presented here consist of four extracts of documents made in deep geological repository sites (for the storage of nuclear waste). Here re-presented are the Yucca Mountain Repository; HADES, in Mol, Belgium; Gorleben in Germany and a further recording from Forsmark in Sweden (pretty much inaudible behind a loop of a pop song). These recordings are imagined acoustic amplifications of deep time, just as the astronomer’s telescope is (thought of a certain way), also a time machine. Stars and nuclear waste are unapparent objects of temporal thought. Andy Weir is an artist from London researching effects of deprioritised subjectivity and contemporary art. This project draws on work developing sonic fictions, stealthy earworms, and micropolitical agencies. Prompted for further thoughts about the recordings presented here, he offered up the interspersed discussion included. —JA Yucca Mountain Repository, Nevada, USA by continent I became interested in these sites originally as spaces that allude to a time outside of the human (‘deep time’) as they are designed to store waste ‘without future maintenance’. The very fact of thinking about these spaces or working on them—engineering etc.. (as I’m particularly interested them in a kind of practice rather than just an object of thought), in other words, forces a confrontation with thought of the extinction of humanity. I was interested in this as a production of affect at odds with the expected ‘ironic, can be whatever you like’ interpretive condition of contemporary art (art under the condition of neoliberalism, say, where the individual subject is prioritised as a free autonomous producer of the meaning of the work) When I thought about this a bit though it ran into paradoxes—yes, I could allude to deep time, but in doing so I just allude to its un-representability, drawing attention to the limits of representation and so reaffirming it—I was stuck in a representation/non-representational negative dialectic. In trying to somehow create a figure for deep time I was either reducing it to my description of it, or presenting it as irreducible. HADES Facility, Mol, Belgium by continent I don’t think I’ve escaped this in the work but my response to it was to create a sonic-fiction. This was based on the idea of a viral transmission of the affect of deep time (this is the ‘pyroclastic-soaked chrono-dread’) through receiving apparatuses, transforming the screen into an intercessor or mediating lure for the outside, a site of exposure multiplying virulently through its dissemination, invoking as much as trying to represent these spaces, the sounds as durations of exposure to contagious materials, and fictions as a way of excavating the strangeness of a world opaque to subjective reconfiguration... Testing out I suppose ways that art could start thinking about figuring the reality of ecological crisis. Gorleben Repository, Lower Saxony, Germany by continent While everything remains at the level of fiction I think the work is problematic. It doesn’t really model anything, giving too much authority to either romantic abandonment or the recuperation of romantic abandonment under its description by theory/philosophy, all contained and controlled by me within a fairly limited condition of what art can do. Deep Time Contagion is precisely a materialisation of and transmission of this paradox (i.e. with screen-media can only present deep time as unrepresentable or draw attention to an inability to present it) taking the comfort/panic induced by this paradox as its material. I’m working now on some new projects that take this as a point of departure. Forsmark Repository, Sweden (Robitussin Mix) by continent. (shrink)

How is it that thoroughly physical material beings such as ourselves can think, dream, feel, create and understand ideas, theories and concepts? How does mere matter give rise to all these non-material mental states, including consciousness itself? An answer to this central question of our existence is emerging at the busy intersection of neuroscience, psychology, artificial intelligence, and robotics.In this groundbreaking work, philosopher and cognitive scientist Andy Clark explores exciting new theories from these fields that reveal minds like ours to (...) be prediction machines - devices that have evolved to anticipate the incoming streams of sensory stimulation before they arrive. These predictions then initiate actions that structure our worlds and alter the very things we need to engage and predict. Clark takes us on a journey in discovering the circular causal flows and the self-structuring of the environment that define "the predictive brain." What emerges is a bold, new, cutting-edge vision that reveals the brain as our driving force in the daily surf through the waves of sensory stimulation. (shrink)

Reid rejects the image theory --the representative or indirect realist position--that memory-judgements are inferred from or otherwise justified by a present image or introspectible state. He also rejects the trace theory , which regards memories as essentially traces in the brain. In contrast he argues for a direct knowledge account in which personal memory yields unmediated knowledge of the past. He asserts the reliability of memory, not in currently fashionable terms as a reliable belief-forming process, but more elusively as a (...) principle of Commonsense. There remains a contemporary consensus against Reid's position. I argue that Reid's critique is essentially sound, and that the consensus is mistaken; personal memory judgements are spontaneous and non-inferential in the same way as perceptual judgements. But I question Reid's account of the connection between personal memory and personal identity. My primary concern is rationally reconstructive rather than scholarly, and downplays recent interpretations of Reid's faculty psychology as a precursor of functionalism and other scientific philosophies of mind.

Recent work in cognitive and computational neuroscience depicts human brains as devices that minimize prediction error signals: signals that encode the difference between actual and expected sensory stimulations. This raises a series of puzzles whose common theme concerns a potential misfit between this bedrock informationtheoretic vision and familiar facts about the attractions of the unexpected. We humans often seem to actively seek out surprising events, deliberately harvesting novel and exciting streams of sensory stimulation. Conversely, we often experience some wellexpected sensations (...) as unpleasant and to-be-avoided. In this paper, I explore several core and variant forms of this puzzle, using them to display multiple interacting elements that together deliver a satisfying solution. That solution requires us to go beyond the discussion of simple information-theoretic imperatives and to recognize the essential role of species-specific prestructuring, epistemic foraging, and cultural practices in shaping the restless, curious, novelty-seeking human mind.

Some regularities enjoy only an attenuated existence in a body of training data. These are regularities whose statistical visibility depends on some systematic recoding of the data. The space of possible recodings is, however, infinitely large – it is the space of applicable Turing machines. As a result, mappings that pivot on such attenuated regularities cannot, in general, be found by brute-force search. The class of problems that present such mappings we call the class of “type-2 problems.” Type-1 problems, by (...) contrast, present tractable problems of search insofar as the relevant regularities can be found by sampling the input data as originally coded. Type-2 problems, we suggest, present neither rare nor pathological cases. They are rife in biologically realistic settings and in domains ranging from simple animat behaviors to language acquisition. Not only are such problems rife – they are standardly solved! This presents a puzzle. How, given the statistical intractability of these type-2 cases, does nature turn the trick? One answer, which we do not pursue, is to suppose that evolution gifts us with exactly the right set of recoding biases so as to reduce specific type-2 problems to type-1 mappings. Such a heavy-duty nativism is no doubt sometimes plausible. But we believe there are other, more general mechanisms also at work. Such mechanisms provide general strategies for managing problems of type-2 complexity. Several such mechanisms are investigated. At the heart of each is a fundamental ploy – namely, the maximal exploitation of states of representation already achieved by prior, simpler learning so as to reduce the amount of subsequent computational search. Such exploitation both characterizes and helps make unitary sense of a diverse range of mechanisms. These include simple incremental learning, modular connectionism, and the developmental hypothesis of “representational redescription”. In addition, the most distinctive features of human cognition – language and culture – may themselves be viewed as adaptations enabling this representation/computation trade-off to be pursued on an even grander scale.

The use of forward models is well established in cognitive and computational neuroscience. We compare and contrast two recent, but interestingly divergent, accounts of the place of forward models in the human cognitive architecture. On the Auxiliary Forward Model account, forward models are special-purpose prediction mechanisms implemented by additional circuitry distinct from core mechanisms of perception and action. On the Integral Forward Model account, forward models lie at the heart of all forms of perception and action. We compare these neighbouring (...) but importantly different visions and consider their implications for the cognitive sciences. We end by asking what kinds of empirical research might offer evidence favouring one or the other of these approaches. (shrink)

There is a definite challenge in the air regarding the pivotal notion of internal representation. This challenge is explicit in, e.g., van Gelder, 1995; Beer, 1995; Thelen & Smith, 1994; Wheeler, 1994; and elsewhere.

Our strategy will be as follows. We begin (Section 1) by offering an account (an example and something close to a definition) of what we shall term Minimal Robust Representationalism (MRR).

We end (Section 4) by making explicit the conditions under which, on our account, a science (e.g., robot- ics) may claim to be addressing cognitive phenomena. (shrink)

It's a presupposition of a very common way of thinking about contextsensitivity in language that the semantic contribution made by a bit of context-sensitive vocabulary is sensitive only to features of the speaker's situation at the time of utterance. I argue that this is false, and that we need a theory of context-dependence that allows for content to depend not just on the features of the utterance's origin, but also on features of its destination. There are cases in which a (...) single utterance semantically conveys different propositions to different members of its audience, which force us to say that what a sentence conveys depends not just on the context in which it is uttered, but also on the context in which it is received.

Connectionism and classicism, it generally appears, have at least this much in common: both place some notion of internal representation at the heart of a scientific study of mind. In recent years, however, a much more radical view has gained increasing popularity. This view calls into question the commitment to internal representation itself. More strikingly still, this new wave of anti-representationalism is rooted not in armchair theorizing but in practical attempts to model and understand intelligent, adaptive behavior. In this paper (...) we first present, and then critically assess, a variety of recent anti-representationalist treatments. We suggest that so far, at least, the sceptical rhetoric outpaces both evidence and argument. Some probable causes of this premature scepticism are isolated. Nonetheless, the anti-representationalist challenge is shown to be both important and progressive insofar as it forces us to see beyond the bare representational/non-representational dichotomy and to recognize instead a rich continuum of degrees and types of representationality.

The side-effect effect is the seemingly irrational tendency for people to say harmful side effects were more intentional than helpful side effects of the same action. But the tendency may not be irrational. According to the Tradeoffs Justification Model, judgments of a person's intentions to cause harm depend on how that person decided to act, and on whether the reasons for acting justified causing the harmful consequences. Across three experiments (N = 660), unjustified harms were viewed as more intentional than (...) justified harms. If the person had a choice of what to do and knowingly caused harm for no good reason, people judged that the person must have actually desired and intended to cause the harm. However, if the person had a strong, compelling reason (e.g., to ransom his daughter from kidnappers) that the observer deemed to have justified causing the harm, then observers thought the harm was weakly intended at most. Taboo harms that violated sacred moral values were especially likely to be seen as intentional because most reasons do not adequately justify violating a sacred value. (shrink)

There is good evidence that, in general, autonomic conditioning in humans occurs only when subjects can verbalize the contingencies of conditioning. However, one form of conditioning, evaluative conditioning (EC), seems exceptional in that a growing body of evidence suggests that it can occur without conscious contingency awareness. As such, EC offers a unique insight into what role contingency awareness might play in associative learning. Despite this evidence, there are reasons to doubt that evaluative conditioning can occur without conscious awareness. This (...) paper aims to critically review the EC literature and to draw some parallels to what is known about autonomic conditioning. In doing so, some important general issues about measuring contingency awareness are raised. These issues are illustrated with a brief report of an experiment in which a sensitive measure of contingency awareness is compared against a commonly used measure. (shrink)

This thesis comprises three main chapters—each comprising one relatively standalone paper. The unifying theme is fragmentalism about truth, which is the view that the predicate “true” either expresses distinct concepts or expresses distinct properties. -/- In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic (...) and semantics that shows how they can answer central conceptual and logical challenges for their view. -/- In Chapter 2, I motivate and develop a modal account of propositions on the basis of an iterative conception of propositions, where the modality is logico-mathematical. The modal account of propositions takes the conception to motivate an inherently potential hierarchy of propositions. I show that the account helps provide satisfying solutions to the intensional paradoxes of Russell-Myhill, Kaplan, and Prior. -/- In Chapter 3, I propose that “true” is polysemous. I suggest that “true” is initially polysemous between correspondence truth and disquotational truth, and further polysemous between the meanings corresponding to the subconcepts of the concept truth generated by the indefinite extensibility of that concept. I show that the proposal provides satisfying solutions to the semantic paradoxes. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Mild Cognitive Impairment:Which Kind Is It?Andy Hamilton (bio)Keywordshuman kinds, mild cognitive impairment, multiple personality disorder, practical kinds, social constructionThere is much stimulating material in the Graham and Ritchie's paper (2006), concerning not just disease-classification but also the ethics of diagnosis. My concern is with the way in which they adduce Ian Hacking's views in the philosophy of science in support of their own. The authors quote with approval his (...) "dynamic nominalism" and its influence on Zachar's concept of "practical kinds." Hacking's view, as the authors quote it, is that "People classified in a certain way tend to conform to or grow into the ways that they are described; but they also evolve in their own ways, so that the classifications and descriptions have to be constantly revised" (1995, 21). The act of classifying changes both the classifier and the subject of classification, resulting in facts and categories that are both socially created and real. Hacking calls this "the looping effect of human kinds," and comments that "Multiple personality [disorder] is an almost too perfect illustration of this feedback effect" (1995, 21). The authors comment that Zachar (2000) builds on Hacking's position, discarding essentialist notions of classification that are limited to inherent biological properties, and turning instead to "practical kinds—nonarbitrary cultural artifacts intended to meet pragmatic needs (e.g. therapeutic, predictive prognostic, labeling effects, and physiology)" (Graham and Ritchie 2006, 36). Practical kinds, they believe, offer a way out of the clinical approach focused on mild cognitive impairment (MCI) as a precursor to, or mild form of, Alzheimer's disease. The inclination of the authors, as I read them, is to treat MCI as a practical or human kind, and not, like Alzheimer's disease, as a natural kind.My concern is whether the "looping effect of human kinds" can be transferred to the case of MCI from Hacking's original case study in Rewriting the Soul, multiple personality disorder (MPD). Hacking wished there to undermine the traditional debate over whether MPD is a "social or psychiatric artifact." He claims, correctly I think, that the presupposition behind the question "Is MPD a real disorder as opposed to a product of social circumstances?" should be rejected. The fact that a disorder is a product of social circumstances does not make it less real (1995, 12). On the looping of human kinds, Hacking comments that "The concept of child abuse [implicated in MPD] may itself be so made and molded by attempts at knowledge and intervention, and social reaction to these studies, that there is no stable object, child abuse, to have knowledge about." This is a "no fact of the matter" response, and it [End Page 51] is based on the recognition of conceptual change. He later adds that child abuse "is a real evil, and it was so before the concept was constructed. It was nevertheless constructed. Neither reality nor construction should be in question" (1995, 61, 68). However, Hacking's conclusions about the reality of MPD express only a muted skepticism. Utilitarian skeptics approach this question by asking, "What is the most effective treatment?" Hacking writes that "in their hearts [such skeptics] suspect that the outcome of multiple therapy [therapy that condones or even encourages the development of multiples in the patient] is a type of false consciousness" (1995, 267). The skeptics about MPD are making a moral judgment, he believes; but on whether that moral judgment is correct, he is silent, although the suspicion must be that he agrees with it.How do these considerations apply to the case of MCI? Graham and Ritchie rightly note that classifying a subject as suffering from MCI, and informing them of the diagnosis, will affect them adversely—it will cause suffering not least because there is at present no cure. However, it must surely be conceded that any disease at all—physical or mental—is a social entity insofar as it involves behavioral ascriptions to the subject concerning their incapacity. The authors also note the vested interests—especially from the pharmaceutical industry—in developing a diagnostic category of MCI. These interests are present in the development of any significant diagnostic... (shrink)

Some probable causes of this premature scepticism are isolated. nonetheless, the anti-representationalist challenge is shown to be both important and progressive insofar as it forces us to see beyond the bare representational/ non-represenational dichotomy and to recognize instead a rich continuum of degrees and types of represenatationality.

Two experiments are described that investigate the effects of attention in moderating evaluative conditioning (EC) effects in a picture‐picture paradigm in which previously discovered experimental artifacts (e.g., Field & Davey, 1999 Field, AP, and Davey, GCL, (1999). Reevaluating evaluative conditioning: A nonassociative explanation of conditioning effects in the visual evaluative conditioning paradigm, Journal of Experimental Psychology. Animal Behavior Processes 25 ((1999)), pp. 211–224.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) were overcome by counterbalancing conditioned stimuli (CSs) and unconditioned stimuli (USs) (...) across participants. Conditioned responses for individuals who had attention enhanced were compared against a control group and groups for whom attention was impeded using a distracter task. In a second experiment the effects of attention were dissociated from those of contingency awareness by using backward‐masked US presentations. The results of these experiments indicate that although associative EC effects may not be disrupted by a lack of contingency awareness, attention is an important factor in establishing conditioning. These results shed some light onto the possible boundary conditions that could explain past inconsistencies in obtaining EC effects in the visual paradigm. (shrink)
