PurposeThis paper aims to explore poverty issues in South Africa, to investigate some of the key contributions that knowledge management can make in the eradication of poverty and to suggest a strategy of knowledge management for poverty eradication in South Africa.Design/methodology/approachThis is a conceptual paper. Secondary data sources, in the form of journal articles, policy documents, newspaper articles and the internet, were consulted.FindingsThis paper contributes to the debates on moving towards an integrated poverty strategy that goes beyond reducing poverty by (...) simply raising national income. The paper advocates for a contextualised knowledge management strategy tailored to specific poverty intervention projects and communities. It also suggests that a knowledge management strategy will result in permanent investment in knowledge and the human development of people.Research limitations/implicationsGiven that this is a conceptual paper, the paper recommends empirical future studies that will implement this strategy within specific poverty-stricken communities in the country.Practical/implicationsThe paper raises awareness among policy and decision-makers of the importance of knowledge management as a tool for poverty eradication. In the knowledge economy, knowledge assets – other than the tangible assets of financial capital and local infrastructure – are the prime creator of wealth. It adds to the body of knowledge on knowledge management for poverty eradication by the World Bank and other international organisations.Social implicationsA knowledge management strategy will create an environment in which human development is attained and the minds of the poor are transformed. It will enhance policy formulation and implementation, empower the poor and create a learning organisation.Originality/valueThe paper presents a proposed strategy for knowledge management for poverty eradication in South Africa.

Attempts to engineer a generally intelligent artificial agent have yet to meet with success, largely due to the (intercontext) frame problem. Given that humans are able to solve this problem on a daily basis, one strategy for making progress in AI is to look for disanalogies between humans and computers that might account for the difference. It has become popular to appeal to the emotions as the means by which the frame problem is solved in human agents. The purpose of (...) this paper is to evaluate the tenability of this proposal, with a primary focus on Dylan Evans’ search hypothesis and Antonio Damasio’s somatic marker hypothesis. I will argue that while the emotions plausibly help solve the intracontext frame problem, they do not function to solve or help solve the intercontext frame problem, as they are themselves subject to contextual variability.

This paper surveys the current philosophical discussion of the ethics of risk imposition, placing it in the context of relevant work in psychology, economics and social theory. The central philosophical problem starts from the observation that it is not practically possible to assign people individual rights not to be exposed to risk, as virtually all activity imposes some risk on others. This is the ‘problem of paralysis’. However, the obvious alternative theory that exposure to risk is justified when its total (...) benefits exceed its total costs faces the standard distributional challenges of consequentialism. Forms of contractualism have been proposed as a solution, but how exactly such theories can be formulated remains problematic, especially when confronted with the difficult cases of mass, novel, risk such as climate change.

In this article, our concern is to describe how body(ies) and self are performed in women’s birth narratives through the mediation of a number of significant elements, including technical devices. We will show how, in these narratives, (1) action is distributed among a series of actants, including professionals and technology; (2) that dichotomies appear which cannot be reduced to one of body/mind, but are more adequately described in terms of ‘body-in-labour’/’embodied self’, each of them being locally performed through the mediation (...) of medical practices, knowledge and technologies, the definition of these elements and of their relations being specific to each obstetrical configuration; (3) that part of professionals’ activities is devoted to the detailed management of the articulation between the body-in-labour and the embodied self, and to monitoring their joint transformations.

This article explores the often-disparate commitments the chaplain has made to both the institutional church as well as the hospital system through the lens of the baptismal rite. As baptism is primarily a religious act meant to initiate new members into the Christian faith and a specific community, the chaplain must grapple with the meaning of baptism in the hospital system, a place of crisis and transient community. It is the numinous presence that binds the chaplain’s disparate commitments together in (...) the liminal space between the clinical and ecclesial within which the chaplain exists. The numinous expands the boundaries of institutions often at odds. The chaplain finds meaning and purpose by bearing witness and remaining committed to this numinous presence that binds. (shrink)

Kendall Walton’s project in ‘Categories of Art’ (1970) is to answer two questions. First, does the history of an artwork’s production determine its aesthetic properties? Second, how – if at all – should knowledge of the history of a work’s production influence our aesthetic judgments of its properties? While his answer to the first has been clearly understood, his answer to the second less so. Contrary to how many have interpreted Walton, such knowledge is not necessary for making aesthetic judgments; (...) perceiving an artwork as belonging to a (correct) category of art requires no art-historical knowledge whatsoever. Moreover, contextualist attempts to incorporate art-historical knowledge via the mechanism of cognitive penetration are incompatible with Walton’s claim that categories of art must be perceptually distinguishable. Here I propose a way of elaborating Walton’s view that avoids this difficulty and reconciles contextualism with aesthetic perception, the view that we perceive aesthetic properties. (shrink)

It has recently become popular to suggest that cognition can be explained as a process of Bayesian prediction error minimization. Some advocates of this view propose that attention should be understood as the optimization of expected precisions in the prediction-error signal (Clark, 2013, 2016; Feldman & Friston, 2010; Hohwy, 2012, 2013). This proposal successfully accounts for several attention-related phenomena. We claim that it cannot account for all of them, since there are certain forms of voluntary attention that it cannot accommodate. (...) We therefore suggest that, although the theory of Bayesian prediction error minimization introduces some powerful tools for the explanation of mental phenomena, its advocates have been wrong to claim that Bayesian prediction error minimization is ‘all the brain ever does’.

What is your authentic self—is it something that you design and create, or something to be discovered within yourself? The philosophical literature remains somewhat divided on this question, and this lack of consensus is also reflected in the popular sphere; in fact, ordinary appeals to the notion of an ‘authentic self’ often involve diverse, if not contradictory, views on selfhood. Interestingly, the self-help psychology of Canadian author and professor Jordan Peterson offers a particularly fitting example of this conflict. The argument (...) that Peterson makes for the importance of personal authenticity in his 2018 book, 12 Rules for Life: An Antidote to Chaos, highlights some of the metaphysical and moral challenges surrounding the concept. In particular, his portrayal of the authentic self demonstrates the degree to which conflicting views of selfhood can coincide: at the same time as his belief in biological essentialism supports a view of the self as genetically fixed, his appeal to social autonomy characterises the self as free and self-determined. Nonetheless, conceiving of the self as constrained in some aspects yet autonomous in others is not an inherently contradictory position. This chapter considers the extent to which these two visions of the self can be reconciled in Peterson’s work and, firmly situated as Peterson is within contemporary discourse, what his ideas on authenticity can tell us about the wider cultural debate.

In this paper we argue that predictive processing (PP) theory cannot account for the phenomenon of affect-biased attention prioritized attention to stimuli that are affectively salient because of their associations with reward or punishment. Specifically, the PP hypothesis that selective attention can be analyzed in terms of the optimization of precision expectations cannot accommodate affect-biased attention; affectively salient stimuli can capture our attention even when precision expectations are low. We review the prospects of three recent attempts to accommodate affect with (...) tools internal to PP theory: Miller and Clark’s (2018) embodied inference; Seth’s (2013) interoceptive inference; and Joffily and Coricelli’s (2013) rate of change of free energy. In each case we argue that the account does not resolve the challenge from affect-biased attention. For this reason, we conclude that prediction error minimization is not sufficient to explain all mental phenomena, contrary to the claim that the PP framework provides a unified theory of all mental phenomena or the brain ‘s cognitive functioning. Nevertheless, we suggest that empirical investigation of the interaction between affective salience and precision expectations should prove helpful in understanding the limits of PP theory, and may provide new directions for the application of a Bayesian perspective to perception.

What kind of moral principle could be sufficiently restrictive to avoid the kind of large-scale risks that have resulted in catastrophe in the past, while at the same time not be so restrictive as to halt desirable progress? Is there such a principle that is not merely a precautionary principle, but one that could be based on firm moral grounds? In this article, I set out to explore a simple idea: might it be the case that reparability could serve as (...) a moral constraint against risky policy decisions? The idea is simple, but comes in two forms. First, that it is morally wrong to impose a risk for harm that is, in principle, irreparable, such that it would bring about a permanent loss of a kind qua kind. Second, that it is morally wrong to impose a risk for a reparable (but not compensable) harm that exceeds what realistically could be repaired. I set out here to do two things. First, I describe the moral problem to be addressed for any principle-guiding decisions about risk. A central claim in this article is that risk decisions are epistemically impaired decisions, and that we must, alongside outcome uncertainty, also take both epistemic uncertainty and moral uncertainty into account. Second, I introduce the idea of reparability as a moral constraint in the form of two versions of the Reparability Principle. Such a principle, I argue, could have some interesting advantages that seem both morally intuitive and that come with some advantages against some of the epistemic challenges posed by risk impositions.

This paper explores the relationship between farmland investment and environmental uncertainty. It examines how farmland investors seek to “render land investible” in spite of drought, groundwater depletion, and changing regulations. To do so, we analyze a single case study: the purchase of 8000 acres of dry rangeland in California’s Cuyama Valley by the Harvard University endowment for use in creating an irrigated vineyard. Drawing from interviews with Cuyama Valley farmers and community members, participant observation at community meetings, and public document (...) analysis, we make two primary contributions to understandings of uncertain resource materiality in farmland investment. First, this case reveals that investors can turn environmental uncertainty into an advantage, exploiting both the temporal uncertainties associated with resource management under climate change and the spatial uncertainties inherent to all subsurface resources. We argue that the material and legal uncertainties of groundwater access provide investors with a potentially lucrative opening to assert their preferred land imaginaries and improve their property values. In the Cuyama Valley they did so through both participation in groundwater governance and the establishment of water-related infrastructure on their property. Second, this case highlights that the asset-making processes involved in farmland investment may be as much vertical as they are horizontal. The need to map and measure the uncertain vertical dimension of land creates an outsized role for scientific expertise in farmland assetization. (shrink)

While the view that we perceive aesthetic properties may seem intuitive, it has received little in the way of explicit defence. It also gives rise to a puzzle. The first strand of this puzzle is that we often cannot perceive aesthetic properties of artworks without training, yet much aesthetic training involves the acquisition of knowledge, such as when an artwork was made, and by whom. How, if at all, can this knowledge affect our perception of an artwork’s aesthetic properties? The (...) second strand of the puzzle arises when we widen the scope of aesthetic experience. The very same aesthetic properties that seem to require training for their perception in artworks do not appear to require training to perceive in objects of everyday aesthetic appreciation and natural phenomena. In this paper I argue that a prominent extant attempt to explain how training is compatible with aesthetic perception—cognitive permeation—is an inadequate solution. I also develop a positive view of aesthetic perception that provides a unified solution to both strands of the puzzle. (shrink)

Data visualization researchers and designers have explored a range of approaches to ensure that non-expert audiences understand and derive value from their work. Using anthropomorphized data graphics—or anthropographics—is one strategy that can help create a connection between data and audiences. Anthropographics have been defined as “visualizations that represent data about people in a way that is intended to promote prosocial feelings or prosocial behavior.” However, during the SARS-CoV-2 pandemic, anthropographics were used in data visualizations that had an expanded range of (...) rhetorical goals beyond promoting prosocial feelings and behavior—for instance, informing people about the pandemic, persuading them to adopt certain behaviors, or memorializing those killed by the virus. In particular, anthropographics were used in visualized simulations to model possible futures for audiences, showing the spread and impact of the virus in various scenarios. These simulations used anthropomorphizing strategies in text as well as in graphics, along with interactive options that enabled audiences to explore personal connections with the data. As demonstrated through a close reading of several of these COVID-19 simulations, anthropographics can be viewed holistically as a design strategy that incorporates text and interactivity as well as graphical marks in representing data. Findings from this analysis suggest several additions to the design space for anthropographics. (shrink)

Through close reading of medical and cultural texts, this article demonstrates how the narrativisation of relational harm underpinned the emerging categorisation of ‘addiction’ in the 19th century: excessive consumption was conceived through its detrimental impact upon others, and more specifically, upon the family. The problem was portrayed as physiological, psychological, and social: ‘addiction’ could not be located securely within a single individual, nor was it conceived simply as a social vice. While other societal themes emerge in the medical writing of (...) the period, such as the relationship between drinking and criminality, and the visibility of drinking in the working-classes, these are not presented as proto-diagnostic criteria in the same way as relational harm. In theorising addiction, medicine relied upon rhetorical devices and narrative modes, and authors and artists took an active role in defining the terms of the debate around drinking, drug use, and gambling. Charles Dickens and George Cruikshank represent childhood through the adult's compulsive behaviour, which the child witnesses, while the adult's behaviour itself is conceived as harm directed towards child. The article demonstrates how 21st-century attitudes, particularly located in the fields of psychiatric diagnosis and child protection social work, echo debates established by 19th-century narratives, arguing that that the disease model of addiction was closely associated with the medico-legal production of childhood. Nineteenth-century narratives of addiction therefore anticipate late 20th- and 21st-century attitudes regarding the impact of parental substance use upon children. (shrink)

By analyzing the discussion on a health forum, we examine how wearing sanitary masks during the Covid-19 pandemic changed people’s lives and what adjustments were required. During our review, we encountered theories referred to by participants as “conspiracy theories” that led to heated exchanges on the forum. Surprisingly, these interactions promoted, rather than prevented, collective exploration and resulted in a rich discussion of the issues related to wearing masks. Using a combination of quantitative and qualitative methods, we first analyze the (...) dynamics of the discussion, its progression, and the conditions under which it was maintained over time, even given the radical expression of irreconcilable positions. Second, we examine the results of the discussion in terms of describing the problems triggered by the mask and the different authorities on which these descriptions were based. We conclude that the boundaries between science and non-science were occasionally blurred because of the wavering of scientific authorities and the uncertainty of the questions related to the pandemic, rather than because of a generalized distrust of science. We recognize that paradoxically, “conspiracist” theories contribute to the production of knowledge and that the adherence to these theories may stem more from the personal experiences of the individuals who profess them, rather than from the contaminating power of conspiracy theories.

This article takes as its point of departure unexpected similarities in the ways that the experimental educator, writer and filmmaker Fernand Deligny and Jean-Luc Nancy conceptualize community. Deligny is remembered for his alternative community for non-speaking children with autism, established in the Cévennes in 1967 and founded on the absence of language and relationality as it is commonly understood. This article probes the paradox that in this community we find a rapprochement with Nancy's relational ontology. Drawing on Deligny's theoretical responses (...) to the dynamics he witnessed and the cartographical methods employed to trasce the movements of the children as they roamed, and placing these in dialogue with Nancy's texts on community through the decades, I suggest a kinship between the two thinkers which opens onto broader questions about the relationship between theories and practices of community.

This article draws on Claude Lévi-Strauss and Michel de Certeau’s theorizations of bricolage in order to explore Bernard Stiegler’s philosophical practice. Taking as its point of departure the elements of intellectual biography provided by Stiegler in Acting Out (2009), it explores his (re)deployment of existing philosophical concepts and the sedimentary nature of his own thought. The article then moves to consider the presence of concepts and practices of mystagogy in Taking Care of Youth and the Generations (2010), arguing that these (...) are a restaging of the dynamics of Acting Out on a collective, rather than an individual scale. Ultimately, the article turns to Stiegler’s late aesthetic writing to explore how his theorization of the roles of amateur and artist might point us towards the lineaments of his unfinished “mystagogy.”.

Does the scope of beliefs that people can form on the basis of perception remain fixed, or can it be amplified with learning? The answer to this question is important for our understanding of why and when we ought to trust experts, and also for assessing the plausibility of epistemic foundationalism. The empirical study of perceptual expertise suggests that experts can indeed enrich their perceptual experiences through learning. Yet this does not settle the epistemic status of their beliefs. One might (...) hold that the background knowledge of experts is the cause of their enriched perceptual experience – what is known as cognitive permeation – and so their subsequent beliefs are only mediately justified because they are epistemically dependent on this background knowledge. I argue against this view. Perceptual expertise is not the result of cognitive permeation but is rather the result of perceptual learning, and perceptual learning does not involve cognition in a way that entails cognitive permeation. Perceptual expertise thus provides a means of widening the scope of the immediately justified beliefs that experts can form. (shrink)

The acquaintance debate in aesthetics has been traditionally divided between pessimists, who argue that testimony does not provide others with aesthetic knowledge of artworks, and optimists, who hold that acquaintance with an artwork is not a necessary precondition for acquiring aesthetic knowledge. In this paper I propose a reconciliationist solution to the acquaintance debate: while aesthetic knowledge can be had via testimony, aesthetic judgment requires acquaintance with the artwork. I develop this solution by situating it within a virtue aesthetics framework (...) based on Ernest Sosa's virtue epistemology. I go on to apply the solution to the debates on moral testimony and expert testimony. An interesting variant on Gettier cases emerges: cases in which subjects have knowledge, but it has been formed by the wrong competence. (shrink)

Because no single person or group holds knowledge about all aspects of research, mechanisms are needed to support knowledge exchange and engagement. Expertise in the research setting necessarily includes scientific and methodological expertise, but also expertise gained through the experience of participating in research and/or being a recipient of research outcomes. Engagement is, by its nature, reciprocal and relational: the process of engaging research participants, patients, citizens and others brings them closer to the research but also brings the research closer (...) to them. When translating research into practice, engaging the public and other stakeholders is explicitly intended to make the outcomes of translation relevant to its constituency of users. In practice, engagement faces numerous challenges and is often time-consuming, expensive and ‘thorny’ work. We explore the epistemic and ontological considerations and implications of four common critiques of engagement methodologies that contest: representativeness, communication and articulation, impacts and outcome, and democracy. The ECOUTER methodology addresses problems of representation and epistemic foundationalism using a methodology that asks, “How could it be otherwise?” ECOUTER affords the possibility of engagement where spatial and temporal constraints are present, relying on saturation as a method of ‘keeping open’ the possible considerations that might emerge and including reflexive use of qualitative analytic methods. This paper describes the ECOUTER process, focusing on one worked example and detailing lessons learned from four other pilots. ECOUTER uses mind-mapping techniques to ‘open up’ engagement, iteratively and organically. ECOUTER aims to balance the breadth, accessibility and user-determination of the scope of engagement. An ECOUTER exercise comprises four stages: engagement and knowledge exchange; analysis of mindmap contributions; development of a conceptual schema ; and feedback, refinement and development of recommendations. ECOUTER refuses fixed truths but also refuses a fixed nature. Its promise lies in its flexibility, adaptability and openness. ECOUTER will be formed and re-formed by the needs and creativity of those who use it. (shrink)

In this project, I develop the concept of a sexualized violence figleaf, a speech mechanism often used in sexualized violence discourse to dismiss or characterize assault as some other kind of thing: a misunderstanding, a change of heart by the victim, a mischaracterization of the perpetrator, or any other number of things which are not rape, or violence. Sexualized violence figleaves are an extension of Jennifer Saul's work on racial and gender figleaves, as the underlying mechanics of the utterance track (...) those of Saul's figleaves. In other words, I am developing a figleaf variant, showing that this conceptual tool is useful for analysing utterances beyond racist, sexist, and conspiracist speech, upon which Saul focuses. Rather, bringing figleaves into the realm of sexualized violence discourse illuminates features of the discourse which are often obscured by the prevalence of strong social intuitions about rapists and their corresponding character.

This paper extends previous attempts at understanding the nature of organizational integrity and its increasingly important role for companies which, after all, bear a moral and societal responsibility. Interpretations of organizational integrity in business ethics literature incorporate aspects ranging from the behavior of managers and employees to corporate structures and incentive systems. We argue that virtue ethics builds an indispensable framework for understanding the origin of the concept of integrity and transfer these findings to an organizational level. Hence, we first (...) define organizational integrity, and second operationalize it in a closed three-step process, consisting of morally sound corporate commitments, their transparent institutionalization within the company, and their implementation into actions. We consider the main goal of organizational integrity to be of a preventative investment nature. Organizational integrity is a company investment that translates into avoiding fines for potential violations of the law or ethical missteps, as well as an investment in the company’s reputation. In turn, organizational integrity can protect a company from disruptions that can threaten its existence. Defining and operationalizing the concept of organizational integrity provides the foundation for future scientific research and the basis for developing practical guidance for organizations and managers.

Within the context of increased global migration and mobility, education occupies a central role which is being transformed by new human movements and cultural diversity, flows, and networks. Studies under the umbrella terms of migration, mobility, and mobilities reveal the complexity of these concepts. The field of study ranges from global child mobility as a response to poverty, to the reconceptualising of notions of inclusion in relation to pastoralist lifestyles, to the ways in which new offshore institutions and transnational diasporas (...) shape the educational experiences of students, families, and teachers. At the heart of this new research is a need to explore how identity, integration, and social stratification play a role in the story of global migration between and within the Global North and South. This volume focuses on three major themes: poverty, migration, social mobility and social reproduction; networks of migration within and across national education systems; and higher education and international student mobility, and the concerns and opportunities that go along with this mobility. The international group of researchers who have contributed to this book demonstrate how educational institutions are part of a common global project characterised by fluidity, how the social fabric of educational institutions responds to demographic diversity, and how new social differentiations occur as a result of human movement. By bringing together these contributions, a number of important theoretical and empirical methodological dimensions are identified that need more attention within the growing field of migration and education studies. This volume shows how mobilities and transnational interconnectedness create multiple interactions that tie our different educational projects together. This book was originally published as a special issue of _Compare: A Journal of Comparative and International Education. _. (shrink)

This study bases itself in the epistemological and methodological development of a broad and interdisciplinary dialogue where various voices in the form of different domains converse in order to establish an integrated whole. The research contributes to the actual corporative question regarding spirituality in the workplace, specifically aimed at the individual in the middle-career phase. This phase is characterised as a re-evaluation period aimed at personal and professional growth. A shift in emphasis to the meaning and sense of work is (...) linked to spiritual intelligence as spirituality can be described and understood as a type of intelligence. The study shows that the middle-career experience provides opportunity for an altered future view. Lifestyle coaching serves as facilitating process and offers guidance in answering existential questions which are included in the spiritual. The probable outcome promises to add meaning as a manifesting component in a dynamic and transforming life strategy. (shrink)

Two approaches to the study of diagnostic thinking are compared, one mainly propositional, namely that of Patel and Groen (1986), the other mainly semantic, that of Lemieux and Bordage (1986). Patel and Groen analyzed the linear dimension of cardiologists' discourses while solving a case of acute bacterial endocarditis, that is, the before and after propositional rules. A secondary analysis of two of their pothophysiological protocols is done using structural semantic techniques from Lemieux and Bordage where the vertical dimension of the (...) discourses is analyzed, that is, the levels of meaning or semantic axes. Contrary to Patel and Groen's position, making an accurate diagnosis is not explained in terms of pure forward reasoning through networks of causal rules, but by means of networks of semantic qualities abstracted from the symptoms and signs. The semantic qualities operate in the clinician's mind in terms of binary oppositions (e.g., sudden-gradual, unilateral-bilateral) whereby each pair of properties constitutes a semantic axis (e.g., sudden-gradual). The successful diagnosticians are those who use the most diversified and pertinent set of semantic axes and, therefore, have a deeper representation of the problem. (shrink)

This article examines motifs of falling, recoiling, and turning across Chester Himes’ oeuvre as figurations of Black susceptibility to racial violence. These images reference and reconstruct an event from Himes’ early adulthood: his catastrophic fall down an elevator shaft. Taking a psychoanalytically oriented approach, I analyze the metonymic connections between these motifs, rather than reading them in their chronological order, using Jean Laplanche’s theory of après-coup. I argue that the recursive quality of these images in Himes’ work is not merely (...) an unconscious repetition or conscious working through of a traumatic biographical event but part of an endeavor to imagine different ways to inhabit and survive the structural trauma of Jim Crow America.

What would political thought look like without the foundation of ethics? Drawing on the work of Emmanuel Levinas, Jacques Derrida and Jean-Luc Nancy, Madeleine Fagan puts forward a radical and far-reaching refusal of foundational ethics. She proposes that politics isn't built on ethics, where the two are separate things: politics and ethics are actually inseparable. The 'ethical' should not be understood as a label; it does not mean 'good' or it is not an evaluation or guide. Rather, both the (...) ethical and the political are descriptions of the context in which we find ourselves. Fagan shows us how it has become necessary to rethink the relationship between ethics and politics, based on how we practice both. In doing so, she overturns a series of common assumptions about poststructuralist ethics. It brings together an exploration of the ethical and political thought of Emmanuel Levinas, Jacques Derrida and Jean-Luc Nancy for the first time. It provides an advanced introduction to poststructuralist ethical thought in politics and international relations. It focuses on the practical political implications of poststructuralist thought.

Perceptual learning is commonly understood as conferring some benefit to the learner, such as allowing for the extraction of more information from the environment. However, perceptual learning can be biased in several different ways, some of which do not appear to provide such a benefit. Here we outline a systematic framework for thinking about bias in perceptual learning and discuss how several cases fit into this framework. We argue these biases are compatible with an understanding in which perceptual learning is (...) beneficial, but that its benefits are tied to both a person's narrow interests and the training environment or domain, and so if there are changes to either of these, then benefits can turn into liabilities, though these are often temporary.

Perceptual learning is an enduring change in the perceptual system – and our resulting perceptions – due to practice or repeated exposure to a perceptual stimulus. It is involved in the acquisition of perceptual expertise: the ability to make rapid and reliable high-level categorizations of objects unavailable to novices. Attentional weighting is one process by which perceptual learning occurs. Advancing our understanding of this process is of particular importance for understanding what is learned in perceptual learning. Attentional weighting seems to (...) favour the hypothesis that what experts learn is simply to better direct their attention to elements of the stimulus relevant to making post-perceptual categorizations. Here I argue against this hypothesis. Attentional weighting is an integral component of the process that allows experts to come to represent high-level properties in perceptual experience. (shrink)
