Expertise is traditionally classified into perceptual, cognitive, and motor forms. I argue that the empirical research literature on expertise gives us compelling reasons to reject this traditional classification and accept an alternative. According to the alternative I support there is expertise in forming impressions, which further divides into expertise in forming sensory and intellectual impressions, and there is expertise in performing actions, which further divides into expertise in performing mental and bodily actions. The (...) traditional category of cognitive expertise splits into two--expertise in forming intellectual impressions and expertise in performing mental actions. I consider and address a challenge to my case in favor of adopting this alternative classification of expertise that derives from dual process theories of cognition. (shrink)

To better understand the nature of joint expertise and its underlying processes, we need not only analyses of the general conditions for skilled group action, but also descriptive accounts of the features and dimensions that vary across distinct performances and contexts, such as sport and the arts. And in addition to positioning our accounts against current models of individual skill, we need concepts and lessons from work on collaborative processes in other cognitive domains. This paper examines ecological or (...) situational components of expert joint action in practice, then offers a selective survey of some key cognitive and affective resources that shape and transform group performance.

Expertise is extended by becoming immersed in cultural practices. We look at an example of mathematical expertise in which immersion in cognitive practices results in the transformation of expert performance.

Practical knowledge is discussed in close relation to practical expertise. For both anti-intellectualists and intellectualists, the knowledge of how to φ is widely assumed to entail the practical expertise in φ-ing. This paper refutes this assumption. I argue that non-experts can know how to φ via other experts’ knowledge of φ-ing. Know-how can be ‘outsourced’. I defend the outsourceability of know-how, and I refute the objections that reduce outsourced know-how to the knowledge of how to ask for help, (...) of how to get things done, or of external contents. Interestingly, outsourcing differs from social cooperation, collective agency, testimonial transmission, and many other notions in social-epistemological debates. Thus, outsourcing provides not only a hitherto unconsidered form of know-how but also a novel way for knowledge to be social. Furthermore, outsourcing plausibly involves a ‘social’ cognitive extension that does not rest on EMT or HEC. Given the outsourceability of know-how, we must reconsider the nature of know-how and expertise, as well as the relation between non-experts and experts. (shrink)

In this paper, I want to make two main points. The first point is methodological: Instead of attempting to give a classical analysis or reductive definition of the term “expertise”, we should attempt an explication and look for what may be called symptoms of expertise. What this comes to will be explained in due course. My second point is substantial: I want to recommend understanding as an important symptom of expertise. In order to give this suggestion content, (...) I begin to develop an account of understanding. Finally, I will draw attention to some consequences of this approach. (shrink)

This chapter argues that gaining expertise can be understood in part as the development of a continuously updated space of adequate knowledge structures or representations that can be defined along different dimensions. It considers the challenge of protecting expertise and harnessing this brittleness from philosophical and cognitive neuroscientific perspectives. The chapter introduces the framework of a Sculpted Space of Actions, in order to explain how the challenge of selecting an adequate option for action is facilitated by (...) class='Hi'>expertise as it helps to constrain the space of potential action options. The emphasis of action‐perception cycles as the main source of the generative models that are being exploited in predictive processing may suggest that it allows no role for the explicit articulated intentions that were found to be an important dimension of the Sculpted Space. The chapter explores whether the integrative cognitive neuroscientific account concurs with what we know about expertise in education. (shrink)

This paper takes an embodied and extended cognition perspective to ER integration – a cognitive process through which a learner integrates external representations in a domain, with her internal model, as she interacts with, uses, understands and transforms between those ERs. In the paper, I argue for a theoretical as well as empirical shift in future investigations of ER integration, by proposing a model of cognitive mechanisms underlying the process, based on recent advances in extended and embodied cognition. (...) I present this new model in contrast to the still dominant classical cognitivist approaches to ER integration, and the educational technology intervention designs such approaches inspire. I then exemplify this distinction between the information processing model and the new model through a case of arithmetic problem solving. Corroborative neuroscience evidence presented in relation to this case provides empirical support for the new model by showing how bodily actions are critical to ER integration and learning. Finally, as educational implications of the new model, I demonstrate the need for: re-viewing the development of ER integration and expertise as fine-tuning of the learner's action or sensorimotor system, and a shift of focus in new-media intervention design principles based on this newer understanding of ER integration in science, technology, engineering and mathematics.

Philosophers and scientists have across the ages been amazed about the fact that development and learning often lead to not just a merely incremental and gradual change in the learner but sometimes to a result that is strikingly different from the learner’s original situation: amazed, but at times also worried. Both philosophical and cognitive neuroscientific insights suggest that experts appear to perform ‘different’ tasks compared to beginners who behave in a similar way. These philosophical and empirical perspectives give some (...) insight into what happens when a novice is transitioning to a stage of expertise. Generally, this implies that increased skill and expertise support better results and a more flexible performance, in part because these allow an agent to withdraw part of her attention and other cognitive resources from the tasks involved, enabling her to devote those resources to supporting, or completely different, tasks. As positive as these developments appear, these changes have also raised concerns. The main concern is whether gaining expertise is like raising a ‘cognitive monster’ which escapes the individual’s conscious control and influences her actions with undesirable automatisms. If so, we should ask ourselves whether experts are capable of taming this monster. The answer appears initially not to be positive. Indeed, it has been noted that since it is difficult for experts to withhold automatic responses this can lead to inflexibility or performance that is only optimal under certain conditions, because it is limited to a specific domain, often context-dependent, biased and inflexible. In what follows, I will consider this challenge of protecting expertise and harnessing this brittleness from philosophical and cognitive neuroscientific perspectives. Taking into account that action is in general determined by a multitude of factors, with learning and development affecting how these factors exert their influence, a philosophical question is how this complex and dynamic process can be explained and subsequently, how controlling it might be understood. First, though, I will present the issue at hand more closely: should we appreciate expertise if it is similar to growing a ‘cognitive monster’? Second, I will introduce the framework of a “Sculpted Space of Actions” (Keestra, 2014), which I developed in order to explain how the challenge of selecting an adequate option for action is facilitated by expertise as it helps to constrain the space of potential action options. Subsequently, the question is raised of how such a Sculpted Space of Actions influences an expert’s engagement with specific situations, like teaching students in a classroom setting. It will be argued that a well prepared expert—teacher or otherwise— is not only able to rely upon her routines but will at the same time be more perceptive and attentive to unforeseen events and actions, according to the recent cognitive neuroscientific theory of Predictive Processing. Integrating the theory of Predictive Processing with the Sculpted Space of Actions framework, I conclude that expertise contributes to adaptive and flexible responses to specific contexts, yet only if it is associated with explicit planning and articulation of situation specific intentions—the latter effectively putting the cognitive monster at rest for a while.

Learning more about philosophical cognition has yielded significant insights into the methods that we employ when doing philosophy, and has led some experimental philosophers to raise concerns about the role that intuitions play in philosophical practice. One popular response to these methodological concerns involves appeal to philosophical expertise, and has become known as the expertise defense because it aims to defend the use of at least some kinds of intuitional evidence in philosophy. The basic idea is that philosophical (...) expertise consists in having developed, through a process of critical reflection, increased conceptual competence and theoretical accuracy, as well as a special knack for reading and thinking about philosophical thought experiments that call upon us to exercise our conceptual competence and theoretical acumen. It turns out to be an open question whether this folk theory of philosophical expertise can restore hope in the value of intuitional evidence, and here we examine two ways of trying to answer that question: one that involves careful reflection on the supposed benefits of philosophical education, and one that involves careful empirical examination of “expert” philosophical intuitions.

It is sometimes said that humans are unlike other animals in at least one crucial respect. We do not simply form beliefs, desires and other mental states, but are capable of caring about our mental states in a distinctive way. We can care about the justification of our beliefs, and about the desirability of our desires. This kind of observation is usually made in discussions of free will and moral responsibility. But it has profound consequences, or so I shall argue, (...) for our conception of the very nature of beliefs and other mental states. Suitably developed, it allows us to draw a line between two distinct ways in which a creature may possess a belief, represent a scene, and fall into error. The first way (which I shall call the 'mindless' way) involves little more than an encoding of information in some way designed to guide appropriate response. This is the common heritage of humans, and many other animals. The second way (which I shall call the 'mindful' way) requires that the creature be capable in addition of a special kind of second-order reflection, and (importantly) be expert at detecting the kinds of situation in which such reflection is called for. The differences between these two ways of 'believing that P' are sufficiently deep and significant to warrant (or so I claim) our treating them as two distinct classes of mental states. For it is only courtesy of the second layer of complexity, I shall argue, that it becomes proper to hold someone accountable for their beliefs or other mental states, and it is this fact of (something like) accountability that in turn raises the most significant challenge for philosophical attempts to give naturalized accounts of meaning, belief, and mentality.

Abstract: Some proponents of “experimental philosophy” criticize philosophers' use of thought experiments on the basis of evidence that the verdicts vary with truth-independent factors. However, their data concern the verdicts of philosophically untrained subjects. According to the expertise defence, what matters are the verdicts of trained philosophers, who are more likely to pay careful attention to the details of the scenario and track their relevance. In a recent article, Jonathan M. Weinberg and others reply to the expertise defence (...) that there is no evidence for such expertise. They now receive a reply in this article, which argues that they have misconstrued the dialectical situation. Since they have produced no evidence that philosophical training is less efficacious for thought experimentation than for other cognitive tasks for which they acknowledge that it produces genuine expertise, such as informal argumentation, they have produced no evidence for treating the former more sceptically than the latter.

Expertise is a cognitive achievement that clearly involves experience and learning, and often requires explicit, time-consuming training specific to the relevant domain. It is also intuitive that this kind of achievement is, in a rich sense, genuinely perceptual. Many experts—be they radiologists, bird watchers, or fingerprint examiners—are better perceivers in the domain(s) of their expertise. The goal of this paper is to motivate three related claims, by substantial appeal to recent empirical research on perceptual expertise: Perceptual (...) expertise is genuinely perceptual and genuinely cognitive, and this phenomenon reveals how we can become epistemically better perceivers. These claims are defended against sceptical opponents that deny significant top-down or cognitive effects on perception, and opponents who maintain that any such effects on perception are epistemically pernicious.

This paper offers a sizeable menu of approaches to what it means to be an expert. Is it a matter of reputation within a community, or a matter of what one knows independently of reputation? An initial proposal characterizes expertise in dispositional terms—an ability to help other people get answers to difficult questions or execute difficult tasks. What cognitive states, however, ground these abilities? Do the grounds consist in “veritistic” states or in terms of evidence or justifiedness? To (...) what extent is expertise a matter of superior knowledge or other factors? Some authors seek to debunk the notion of expertise entirely. The present approach resists this stance, but doesn’t dispute the variability and fluidness of the concept. Even more challenging is the problem of how laypersons can determine who is the superior expert, especially when experts disagree. (shrink)

This paper surveys recent work on moral expertise. Much of that work defends an asymmetry thesis according to which the cognitive deference to expertise that characterizes other areas of inquiry is out of place in morality. There are two reasons why you might think asymmetry holds. The problem might lie in the existence of expertise or in deferring to it. We argue that both types of arguments for asymmetry fail. They appear to be stronger than they (...) are because of their focus on moral expertise regarding all-in judgments about rightness. We reject this emphasis on all-in judgment in favor of an account of moral expertise as typically multi-stranded and domain limited. This account of moral expertise is better able to address the problem of how to identify those who have expertise. It also offers a more nuanced picture of the contrast between accepting a moral claim on one’s own and accepting it on testimony. (shrink)

Although taste and smell seem hard to imagine, some people nevertheless report vivid imagery in these sensory modalities. We investigate whether experts are better able to imagine smells and tastes because they have learned the ability, or whether they are better imaginers in the first place, and so become experts. To test this, we first compared a group of wine experts to yoked novices using a battery of questionnaires. We show for the first time that experts report greater vividness of (...) wine imagery, with no difference in vividness across sensory modalities. In contrast, novices had more vivid color imagery than taste or odor imagery for wines. Experts and novices did not differ on other vividness of imagery measures, suggesting a domain‐specific effect of expertise. Critically, in a second study, we followed a group of students commencing a wine course and a group of matched control participants. Students and controls did not differ before the course, but after the wine course students reported more vivid wine imagery. We provide evidence that expertise improves imagery, exemplifying the extent of plasticity of cognition underlying the chemical senses. (shrink)

Between formal propositional knowledge and embodied skill lies ‘interactional expertise’—the ability to converse expertly about a practical skill or expertise, but without being able to practice it, learned through linguistic socialisation among the practitioners. Interactional expertise is exhibited by sociologists of scientific knowledge, by scientists themselves and by a large range of other actors. Attention is drawn to the distinction between the social and the individual embodiment theses: a language does depend on the form of the bodies (...) of its members but an individual within that community can learn the language without the body. The idea has significance for our understanding of colour-blindness, deafness and other abilities and disabilities. They say that love's a word. (shrink)

In this article, we discuss expertise by considering the activity of reading. Cognitive scientists have traditionally conceptualised reading as a single, well-defined task, namely the decoding of letter sequences into meaningful sequences of speech sounds. This definition captures a core feature of the reading activity at the computational level, but it is an overly narrow model of how reading behaviour occurs in the real world. We propose a more expansive model of expertise. In our view, expertise (...) in general is best conceptualised as a distributed process that takes place within a cultural-cognitive ecosystem. Our model allows for a more inclusive view of expertise in reading. We argue that reading is better understood as a manifold task domain that admits multiple reasonable criteria for evaluating performance. We draw on ethnographic data to show how our model allows for a wider appreciation of what expertise in reading amounts to in educational contexts. (shrink)

The paper presents two empirical cases of expert musicians—a classical string quartet and a solo, free improvisation saxophonist—to analyze the explanatory power and reach of theories in the field of expertise studies and joint action. We argue that neither the positions stressing top-down capacities of prediction, planning or perspective-taking, nor those emphasizing bottom-up embodied processes of entrainment, motor-responses and emotional sharing can do justice to the empirical material. We then turn to hybrid theories in the expertise debate and (...) interactionist accounts of cognition. Attempting to strengthen and extend them, we offer ‘Arch’: an overarching conception of musical interaction as an externalized, cognitive scaffold that encompasses high and low-level cognition, internal and external processes, as well as the shared normative space including the musical materials in which the musicians perform. In other words, ‘Arch’ proposes interaction as a multivariate multimodal overarching scaffold necessary to explain not only cases of joint performance, but equally of solo improvisation. (shrink)

Acquiring expertise in a task is often thought of as an automatic process that follows inevitably with practice according to the log‐log law (aka: power law) of learning. However, as Ericsson, Chase, and Faloon (1980) showed, this is not true for digit‐span experts and, as we show, it is certainly not true for Tetris players at any level of expertise. Although some people may simply “twitch” faster than others, the limit to Tetris expertise is not raw keypress (...) time but the techniques acquired by players that allow them to use the tools provided by the hardware and software to compensate for the game's relentlessly increasing drop speed. Unfortunately, these increases in drop speed between Tetris levels make performance plateaus very short and quickly followed by game death. Hence, a player's success at discovering, exploring, and practicing new techniques for the tasks of board preparation, board maintenance, optimal placement discovery, zoid rotation, lateral movement of zoids, and other tasks important to expertise in Tetris is limited. In this paper, we analyze data collected from 492 Tetris players to reveal the challenges they confronted while constructing expertise via the discovery of new techniques for gameplay at increasingly difficult levels of Tetris.

Rather than ask if expertise is under threat, this paper uses case studies to show how expertise is enabled. Its appearance can be traced to how the already known evokes sensibility, judging, thinking and languaging. As defined below, it draws on epistemic cycles. Using Secchi and Cowley’s (2021) 3M model, this posits a second cut between the micro and the macro. In the mesosphere, people create temporary domains or what William James (1991) calls ‘little worlds’. Within these corpora (...) popularia, the new is made possible – expertise sets off unimagined outcomes. Thus, many concerns cannot be solved by scientific correlates of a natural ontological attitude: indeed, the truism clarifies many social challenges. We lack social institutions that dedicate expertise to goals like ecosocial justice and life-sustaining relations. Once the necessary expertise is traced to epistemic cycles, we can demand of institutions that they create bodies that seek to bring a rich future to evolution. (shrink)

Interactional expertise is here to stay. Undoubtedly, in some sense of the word, one can attain a linguistic expert level within a field without full scale practical immersion. In the context of the idea of embodied cognition, the claim is provocative. How can an interactional expert acquire full linguistic competence without the simultaneous bodily engagement and real life interaction needed to get the language right? How can one understand the concept of hammering if one has never seen a hammer (...) or felt the weight of the iron head on a fragile thumb? Here I will explore a strange and second-hand way in which bodily engagement could have an impact on our linguistic abilities; this is via the so called mirror neuron system. Since the mirror neuron system blurs the distinction between first and third person activity it can help us understand some of the enigmatic aspects of interactional expertise and pose further questions for research.Keywords: Mirror neurons; Interactional expertise; Contributory expertise; Embodied knowledge; Evolution.

One of the most influential studies in all expertise research is de Groot’s (1946) study of chess players, which suggested that pattern recognition, rather than search, was the key determinant of expertise. Many changes have occurred in the chess world since de Groot’s study, leading some authors to argue that the cognitive mechanisms underlying expertise have also changed. We decided to replicate de Groot’s study to empirically test these claims and to examine whether the trends in (...) the data have changed over time. Six Grandmasters, five International Masters, six Experts, and five Class A players completed the think-aloud procedure for two chess positions. Findings indicate that Grandmasters and International Masters search more quickly than Experts and Class A players, and that both groups today search substantially faster than players in previous studies. The findings, however, support de Groot’s overall conclusions and are consistent with predictions made by pattern recognition models. (shrink)

_Expertise, Pedagogy and Practice_ takes as its focus recent work on situated and embodied cognition, the concepts of expertise, skill and practice, and contemporary pedagogical theory. This work has made important steps towards overcoming traditional intellectualist and individualist models of cognition, group interaction and learning, but has in turn generated a number of important questions about the shape of a model that emphasizes learning and interaction as situated and embodied. Bringing together philosophers, cognitive scientists and education theorists, the (...) collection asks and explores a variety of different questions. Can a group learn? Is expertise distributed? How can we make sense of a normative dimension of expertise or skill? How situation-specific is expertise? How can groups shape or generate expert practice? Through these lenses, this collection advances a more experientially holistic approach to the characterisation and growth of human expertise. This book was originally published as a special issue of _Educational Philosophy and Theory. _. (shrink)

This paper has a twofold aim. On the one hand, we will discuss the much debated question of the source of normativity (which traditionally has nature and practical reason as the two main contenders to this role) and propose a new answer to it. Second, in answering this question, we will present a new account of practical wisdom, which conceives of the ethical virtues as ultimately unified in the chief virtue of phronesis, understood as ethical expertise. To do so, (...) we will first criticize the main current view of phronesis and its bearer (the phronimos), then offer another view of the nature of phronesis and of its relation to the other ethical virtues. Our proposal should not be intended as an interpretation of Aristotle’s own view; rather, it should be seen as a broadly Aristotelian theoretical proposal, which we believe can satisfyingly address most of the problems that afflict the more traditional accounts of practical wisdom. In section 2 of this paper, after criticizing first-nature naturalistic views of moral virtue, we take practical reason to be the cornerstone of second-nature naturalistic views; in section 3, we will outline criticisms to which, in our view, the traditional views of phronesis are ill-suited to respond, and, in section 4, we will outline our view of phronesis as ethical expertise – a view which in our view is immune to the above-mentioned criticisms – by spelling out the three main tenets of phronesis as ethical expertise: a conceptual thesis, an epistemic thesis, and the educational implications of the two. Finally, we will support our proposal with some empirical evidence taken from cognitive science. (shrink)

Should the development of pharmacological cognitive enhancers raise worries about doping in cognitively demanding activities? In this paper, we argue against using current evidence relating to enhancement to justify a ban on cognitive enhancers using the example of chess. It is a mistake to assume that enhanced cognitive functioning on psychometric testing is transferable to chess performance because cognitive expertise is highly complex and in large part not merely a function of the sum specific sub-processes. (...) A deeper reason to doubt that pharmacological cognitive enhancers would be as significant in mind sports is the misleading parallel with physical enhancement. We will make the case that cognitive performance is less mechanical in nature than physical performance. We draw lessons from this case example of chess for the regulation of cognitive enhancement more generally in education and the professions. Premature regulation runs the risk of creating a detrimental culture of suspicion that ascribes unwarranted blame. (shrink)

Body representations are known to be dynamically modulated or extended through tool use. Here, we review findings that demonstrate the importance of a user's tool experience or expertise for successful tool embodiment.

Expertise has become a topic of increased interest to philosophers. Fascinating in its own right, expertise also plays a crucial role in several philosophical debates. My aim in this paper is to draw attention to an important, and hitherto unappreciated feature of expertise: its brittleness. Experts are often unable to transfer their proficiency in one domain to other, even intuitively similar domains. Experts are often unable to flexibly respond to changes within their domains. And, even more surprisingly, (...) experts will occasionally be outperformed by novices when confronted with novel circumstances within their domains of expertise. In section 1, I marshal the evidence in favour of brittleness. In section 2, I argue that appeals to brittleness can advance the dialectic in debates on skilled action and provide reasons to reject a powerful recent argument offered by Christensen et al. : 693–719, 2019). In section 3, I appeal to brittleness to argue against a common conception of philosophical expertise, according to which philosophers possess a domain-general set of reasoning skills. Although my argument in this section is largely negative, there is a twist. Recalibrating our understanding of philosophical expertise opens new avenues of research for defenders of the so-called ‘expertise defence’ against the findings of experimental philosophy. (shrink)

We apply a cognitive modeling approach to the problem of measuring expertise on rank ordering problems. In these problems, people must order a set of items in terms of a given criterion (e.g., ordering American holidays through the calendar year). Using a cognitive model of behavior on this problem that allows for individual differences in knowledge, we are able to infer people's expertise directly from the rankings they provide. We show that our model-based measure of (...) class='Hi'>expertise outperforms self-report measures, taken both before and after completing the ordering of items, in terms of correlation with the actual accuracy of the answers. These results apply to six general knowledge tasks, like ordering American holidays, and two prediction tasks, involving sporting and television competitions. Based on these results, we discuss the potential and limitations of using cognitive models in assessing expertise. (shrink)

L’expertise se trouve bien souvent au cœur des dossiers judiciaires relatifs à la responsabilité en matière de santé publique. L’expert est chargé de reconstituer les faits ou d’évaluer le travail de ses collègues agissant comme conseillers des décideurs, pour établir si la qualité de l’expertise et du conseil a été à la hauteur des enjeux sanitaires. En France, les experts judiciaires ont un statut officiel à l’issue d’un processus réglementé et de contrôles spécifiques réguliers. Si cette procédure permet (...) d’identifier clairement les compétences des experts agréés, elle rend difficile, par sa lourdeur, l’accès des chercheurs à ce statut.

Experts are required to reconstruct facts or to appraise the work of colleagues who act in an advisory capacity to policy-makers, in order to establish whether the quality of the expert studies and advice provided have been adequate to the importance of the health issues. In France, expert witnesses have an official status subject to a regulated procedure that includes specific and regular audits. Although this procedure clearly identifies the competences of court-appointed experts, it is far too lengthy and cumbersome for researchers to gain access to this status. Clearer procedures capable of distinguishing expert appraisals from lobbying also need to be established. (shrink)

We provide the first demonstration of an artificial neural network encoding the perceptual templates that form an important component of the high level strategic understanding developed by experts. Experts have a highly refined sense of knowing where to look, what information is important and what information to ignore. The conclusions these experts reach are of a higher quality and typically made in a shorter amount of time than those of non-experts. Understanding the manifestation of such abilities in terms of both (...) the psychology of expert performance and the underlying neural mechanisms constitutes one of the most challenging problems in the cognitive sciences. Using perceptual templates we show how the amount of contextual information can change significantly even within a given task, the relationship between local and non-local contexts and finally why there is very little correlation between measures of intelligence and level of expertise in many of the most complex tasks performed by humans.

There are good, even if inconclusive, reasons to think that cognitive penetration of perception occurs: that cognitive states like belief causally affect, in a relatively direct way, the contents of perceptual experience. The supposed importance of – indeed as it is suggested here, what is definitive of – this possible phenomenon is that it would result in important epistemic and scientific consequences. One interesting and intuitive consequence entirely unremarked in the extant literature concerns the perception of art. Intuition (...) has it that knowledge about art changes how one aesthetically evaluates artworks. A profound explanation of this intuitive fact is that perceptual experiences vary with artistic expertise. Cognitive penetration provides an explanatory mechanism for this latter effect. What one knows or otherwise thinks about art may affect, in one of two ways sketched below, how one perceives art. Differences in aesthetic evaluation may follow, either because high-level aesthetic properties can be perceptually represented or because they causally depend on low-level perceptible properties. All of this lends credence to the hypothesis that the expert better judges art because she better perceives art. And she better perceives art because she better knows art. (shrink)

The paper analyzes, on the basis of Ryle’s concepts of knowledge that and knowledge how, both objectified forms of expert knowledge and the performative nature of expertise. Both theoretical and practical aspects of the identified categories are studied from historical and social perspectives as phenomena characteristic of post-modern information society. In virtue of the selected social examples an epistemological model of performative expert knowledge and expertise is constructed in which crucial elements are distinguished: experts’ cognitive attitudes and (...) dispositions, intellectual skills, intuition and mistakes as well as types of interactional versus contributory expertise. Also considered are the epistemological consequences derived from the research concerning expertise in psychiatric treatment where both expert knowledge and expertise fall into line with institutional requirements as well as procedures.

Dustin Stokes’s book contributes to one of the continuing debates in empirically informed philosophy of mind and cognitive sciences which concerns the relation between thought and perception. The book sheds new light on such questions as: whether vision is modular, informationally encapsulated, and thus cognitively impenetrable or rather the opposite – whether it is malleable and sensitive to further improvements by cognitive states. Stokes supports the latter by referring to empirical evidence on perceptual expertise. Proponents of the (...) modular and malleable architectures of the mind offer different explanations of the phenomena involved in perceptual expertise, viz. object identification and categorization. Interestingly, both views assume some kind of automaticity of the recognitional capacities for identifying and categorizing objects. In this article, I examine the influence of perceptual expertise on object recognition and how the seeming automaticity of object recognition may be approached from the modularist and antimodularist (malleabilist) perspectives.

Many degree programs in science and engineering aim at enabling their students to perform interdisciplinary problem solving. In this paper we present three types of expertise that are involved in different ways in interdisciplinary problem solving. In doing so we shall first characterise two important epistemological challenges commonly faced in interdisciplinary problem solving, namely the communication challenge that arises from the use of different concepts within different scientific domains, and the integration challenge that arises from the differences between domain-specific (...) epistemological standards. Next, drawing on recent work on expertise developed within science studies, we characterize the interactional expertise that is a precondition for scientists to communicate across scientific domains, and the integrational expertise that is a precondition for scientists to be able to integrate cognitive resources originating in different domains. Finally, we shall analyse how different types of interdisciplinary problem solving sets different requirements for interactional and integrational expertise and discuss the implications for science and engineering programs in higher education.

In this paper, we advance the thesis that music-making can be advantageously understood as an exploratory phenomenon. While music-making is certainly about aesthetic expression, from a phenomenological, cognitive, and even evolutionary perspective, it more importantly concerns structured explorations of the world around us, our minds, and our bodies. Our thesis is based on an enactive and phenomenological analysis of three cases: the first concerns the study of infants involved in early musical activities, and the two latter are phenomenologically inspired (...) interviews with an expert jazz improviser, and members of a prominent string quartet. Across these examples, we find that music-making involves a dual intentionality - one oriented towards the exploration of the sonic, material, and social environment, and one oriented toward the self, including the exploration of bodily awareness and reflective mental states. In enactivist terms, exploration is a fundamental way of making sense of oneself as coupled with the world. Understanding music-making as a pre-eminent case of exploration helps us explicate and appreciate the developmental, sensorimotor, and more advanced cognitive resources that exist in music-making activities.

The topic of expertise has become especially lively in recent years in academic discussions and debates about the politics of science. It is easy to understand why the topic holds such strong interest in Science & Technology Studies and related fields. There are at least two basic reasons for such interest. One is that experts are undoubtedly important in modern societies, and the other is that trends in STS research tend to be critical of the cognitive authority associated (...) with the public role of the expert. Putting the two together, STS researchers often align themselves with environmentalist and other movements that question the impartiality of experts and seek to democratize decisions about science and technology. Though such alignment is in many respects laudable, it can also be a source of confusion and misplaced political criticism. Toward the end of this brief synopsis of current STS research and debates on the topic of expertise, I will suggest an alternative agenda for engaging the politics of science and technology. (shrink)
