Perceptual attention is essential to both thought and agency, for there is arguably no demonstrative thought or bodily action without it. Psychologists and philosophers since William James have taken attention to be a ubiquitous and distinctive form of consciousness, one that leaves a characteristic mark on perceptual experience. As a process of selecting specific perceptual inputs, attention influences the way things perceptually appear. It may then seem that it is a specific feature of perceptual representation that constitutes what it is (...) like to consciously attend to an object. In fact conscious attention is more complicated. In what follows, I argue that the phenomenology of conscious attention to what is perceived involves not just a way of perceptually locking on to a specific object. It necessarily involves a way of cognitively locking on to it as well. (shrink)

This paper considers the connection between automaticity, control and agency. Indeed, recent philosophical and psychological works play up the incompatibility of automaticity and agency. Specifically, there is a threat of automaticity, for automaticity eliminates agency. Such conclusions stem from a tension between two thoughts: that automaticity pervades agency and yet automaticity rules out control. I provide an analysis of the notions of automaticity and control that maintains a simple connection: automaticity entails the absence of control. An appropriate analysis, however, shows (...) that actions are forms of control and pervasively automatic even if automaticity implies the absence of control. Consequences are drawn for the theory of mental agency and the psychological concepts of automaticity and control. (shrink)

Field theories have been central to physics over the last 150 years, and there are several theories in contemporary physics in which physical fields play key causal and explanatory roles. This paper proposes a novel field trope-bundle (FTB) ontology on which fields are composed of bundles of particularized property instances, called tropes and goes on to describe some virtues of this ontology. It begins with a critical examination of the dominant view about the ontology of fields, that fields are properties (...) of a substantial substratum. (shrink)

Commentators divide on whether the basic elements of Hume’s philosophy—perceptions, their division into impressions and ideas, and their associative relation—should be construed as objects and relations between objects or as representations of objects and their relations. Although the latter reading is generally favored, in this chapter the author argues that the textual evidence favors the former and that Hume’s philosophy should be interpreted accordingly. The focus is on Part 1 of the first book of the Treatise but subsequent texts are (...) considered as well, particularly passages in Part 4, Sections 2 and 6. (shrink)

There is no consensus on how to define substance, but one popular view is that substances are entities that are independent in some sense or other. E. J. Lowe’s version of this approach stresses that substances are not dependent on other particulars for their identity. I develop the meaning of this proposal, defend it against some criticisms, and then show that others do require that the theory be modified.

This paper answers several open questions around structures with o‐minimal open core. We construct an expansion of an o‐minimal structure by a unary predicate such that its open core is a proper o‐minimal expansion of. We give an example of a structure that has an o‐minimal open core and the exchange property, yet defines a function whose graph is dense. Finally, we produce an example of a structure that has an o‐minimal open core and definable Skolem functions, but is not (...) o‐minimal. (shrink)

Subjectivism about normativity (SN) is the view that norms are never intrinsic to things but are instead always imposed from without. After clarifying what SN is, I argue against it on the basis of its implications concerning intentionality. Intentional states with the mind-to-world direction of fit are essentially norm-subservient, i.e., essentially subject to norms such as truth, coherence, and the like. SN implies that nothing is intrinsically an intentional state of the mind-to-world sort: its being such a state is only (...) a status relative to the imposition of a norm. If one rejects this view of mind-to-world states, then one has grounds for rejecting SN itself. If one accepts it, an infinite regress arises that makes it impossible for norms to be imposed, which means that SN has undermined itself. (shrink)

In this paper, I argue that visual attention is cognitively penetrated by intention. I present a detailed account of attention and its neural basis, drawing on a recent computational model of neural modulation during attention: divisive normalization. I argue that intention shifts computations during divisive normalization. The epistemic consequences of attentional bias are discussed.

Movements of the Mind is about what it is to be an agent. Focusing on mental agency, it integrates multiple approaches, from philosophical analysis of the metaphysics of agency to the activity of neurons in the brain. Philosophical and empirical work are combined to generate concrete explanations of key features of the mind. The book should be relevant and accessible to philosophers and scientists interested in mind and agency.

Is vision informationally encapsulated from cognition or is it cognitively penetrated? I shall argue that intentions penetrate vision in the experience of visual spatial constancy: the world appears to be spatially stable despite our frequent eye movements. I explicate the nature of this experience and critically examine and extend current neurobiological accounts of spatial constancy, emphasizing the central role of motor signals in computing such constancy. I then provide a stringent condition for failure of informational encapsulation that emphasizes a computational (...) condition for cognitive penetration: cognition must serve as an informational resource for visual computation. This requires proposals regarding semantic information transfer, a crucial issue in any model of informational encapsulation. I then argue that intention provides an informational resource for computation of visual spatial constancy. Hence, intention penetrates vision. (shrink)

We present a synthetic theory of skilled action which proposes that cognitive processes make an important contribution to almost all skilled action, contrary to influential views that many skills are performed largely automatically. Cognitive control is focused on strategic aspects of performance, and plays a greater role as difficulty increases. We offer an analysis of various forms of skill experience and show that the theory provides a better explanation for the full set of these experiences than automatic theories. We further (...) show that the theory can explain experimental evidence for skill automaticity, including evidence that secondary tasks do not interfere with expert performance, and evidence that experts have reduced memory for performance of sensorimotor skills.

The phrase ‘trading zone’ is often used to denote any kind of interdisciplinary partnership in which two or more perspectives are combined and a new, shared language develops. In this paper we distinguish between different types of trading zone by asking whether the collaboration is co-operative or coerced and whether the end-state is a heterogeneous or homogeneous culture. In so doing, we find that the voluntary development of a new language community—what we call an inter-language trading zone—represents only one of (...) four possible configurations. In developing this argument we show how different modes of collaboration result in different kinds of trading zone, how different kinds of trading zone may be ‘nested’ inside each other and discuss how a single collaboration might move between different kinds of trading zone over time. One implication of our analysis is that interactional expertise is a central component of at least one class of trading zone.Keywords: Trading zones; Interactional expertise; Interdisciplinarity; Creole.

Do self‐monitoring accounts, a dominant account of the positive symptoms of schizophrenia, explain auditory verbal hallucination? In this essay, I argue that the account fails to answer crucial questions any explanation of auditory verbal hallucination must address. Where the account provides a plausible answer, I make the case for an alternative explanation: auditory verbal hallucination is not the result of a failed control mechanism, namely failed self‐monitoring, but, rather, of the persistent automaticity of auditory experience of a voice. My argument (...) emphasizes the importance of careful examination of phenomenology as providing substantive constraints on causal models of the positive symptoms in schizophrenia. (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.

There are theoretical limitations to what can be implemented by a computer program. In this paper we are concerned with a limitation on the strength of computer implemented deduction. We use a version of the Curry paradox to arrive at this limitation.

In response to Mole 2009, I present an argument for zombie action. The crucial question is not whether but rather to what extent we are zombie agents. I argue that current evidence supports only minimal zombie agency.

Andrew Wayne discusses some recent attempts to account, within a Bayesian framework, for the "common methodological adage" that "diverse evidence better confirms a hypothesis than does the same amount of similar evidence". One of the approaches considered by Wayne is that suggested by Howson and Urbach and dubbed the "correlation approach" by Wayne. This approach is, indeed, incomplete, in that it neglects the role of the hypothesis under consideration in determining what diversity in a body of evidence (...) is relevant diversity. In this paper, it is shown how this gap can be filled, resulting in a more satisfactory account of the evidential role of diversity of evidence. In addition, it is argued that Wayne's criticism of the correlation approach does not indicate a serious flaw in the approach. (shrink)

The notion of common ground is important for the production of referring expressions: In order for a referring expression to be felicitous, it has to be based on shared information. But determining what information is shared and what information is privileged may require gathering information from multiple sources, and constantly coordinating and updating them, which might be computationally too intensive to affect the earliest moments of production. Previous work has found that speakers produce overinformative referring expressions, which include privileged names, (...) violating Grice’s Maxims, and concluded that this is because they do not mark the distinction between shared and privileged information. We demonstrate that speakers are in fact quite effective in marking this distinction in the form of their utterances. Nonetheless, under certain circumstances, speakers choose to overspecify privileged names. (shrink)

Jean Ayres invented Sensory Integration for children experiencing learning and social difficulties because, according to Ayres, they could not adequately integrate information from multiple sensory modalities. She established a scientific basis for her identification of children with sensory integrative difficulties, using statistical techniques to identify symptoms and neuroscience to determine a cause. She was an unusually reflective practitioner who catalyzed a community of practice around SI without becoming a guru—indeed, she encouraged her students to come up with their own ideas (...) and test them empirically. She felt isolated from the growing field of Occupational Therapy yet is viewed as one of its greatest pioneers. After her death in 1988, the SI community gradually began to argue about fundamental issues like what should constitute an appropriate diagnosis and set of tests for SI. At present, the network is fragmented to the point where some of the opposing positions may be incommensurable with each other, which would require a trading zone. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Imperfect Men in Perfect Societies:Human Nature in UtopiaGorman BeauchampIUtopists view man as a product of his social environment. Nothing innate in the psychic make-up of man—no inherent flaw in his nature, no inheritance of original sin—prevents his being perfected, or at least radically ameliorated, once the social structure that shapes character can be properly reordered. Utopists, in short, deny that there is such a thing as "human nature"—if, as (...) John Plamenatz suggests, to say that something is human nature is just another way of saying that it cannot be changed.1 To accept the psychic constitution of man as fixed, immutable, is anathema to utopists, who agree rather with Ortega y Gasset: "Man has no nature. What he has is history."2 The social conditions that have obtained historically, that is to say, have made man what he has been—anything but utopian; but if man's history could be changed, so could his "nature." The idea of Progress, so pervasive in the West from the seventeenth century on, lends some credence to this contention. W. D. Howells's Altrurians, their creator notes, "get some sad amusement out of the fact that the capitalist world believes human nature cannot be changed, though cannibalism and slavery and polygamy have all been extirpated in the so-called Christian countries, and these things were once human nature, which is always changing...."3 Utopia is merely a means, then, of imaginatively expediting, directing, culminating the historically progressive creation of a morally exemplary race of men.The environmentalist psychology espoused by utopists springs from one of two anterior assumptions (although in the creation of many fictional idola the distinction between them is often blurred). The first [End Page 280] assumption is formulated most famously by Rousseau in the Discourse on Inequality: that "man is naturally good, and only by his institutions is he made bad."4 The second assumption is formulated most famously by Locke in the Essay Concerning Human Understanding: that the mind—and by extension the character—is a tabula rasa that takes impression from the stimuli exerted by the external world and thus is neither innately good or bad, but plastic, malleable.5 An intriguing conflation of these two theories operates, for instance, in the psyche of the monster in Mary Shelley's Frankenstein. In the long middle section of the book, where the monster's side of the story is presented sympathetically, his character develops in a text-book demonstration of Lockean psychology; yet, at the same time, this lumbering tabula rasa quivers with enough benevolence (the implausible provenance of which mystifies) to put most saints to shame. He becomes evil and destructive only after being persecuted unmercifully for his misshapen appearance.6 Indeed, the criminal career of Mary Shelley's monster rehearses the common utopian argument that society's injustice to man (or monster) is the source of his crimes. "With our present state of society," writes James Casey in A New Moral World (1885), "we manufacture criminals and then punish them for being so."7 H. G. Wells, in A Modern Utopia (1905), concurs: "Crime and bad lives are the measure of the State's failure, all crime in the end is the crime of the community."8 And both are but restating the charge of Sir Thomas More's Raphael Hytholoday, leveled several centuries earlier in the original Utopia (1519): "If you allow people to be badly brought up and their habits to be corrupted little by little from childhood and if you then punish them for crimes to which their early training has disposed them, what else is this, I ask, but first making them thieves and then punishing them for it?"9 Evil deeds, then, to reiterate the utopist's point, result not from some vicious mole in human nature, but from the malfunctioning of society itself. Utopia, by contrast, is—or theoretically ought to be—a world without crime.Rousseau's concept of the innate goodness of man and the evil of his institutions most often informs primitivist models of utopia, exotic worlds inhabited by noble savages uncorrupted by civilization. The idealized Indians of Montaigne's essay... (shrink)

There is significant interest in type-free systems that allow flexible self-application. Such systems are of interest in property theory, natural language semantics, the theory of truth, theoretical computer science, the theory of classes, and category theory. While there are a variety of proposed type-free systems, there is a particularly natural type-free system that we believe is prototypical: the logic of recursive algorithms. Algorithmic logic is the study of basic statements concerning algorithms and the algorithmic rules of inference between such statements. (...) As shown in [1], the threat of paradoxes, such as the Curry paradox, requires care in implementing rules of inference in this context. As in any type-free logic, some traditional rules will fail. The first part of the paper develops a rich collection of inference rules that do not lead to paradox. The second part identifies traditional rules of logic that are paradoxical in algorithmic logic, and so should be viewed with suspicion in type-free logic generally. (shrink)

ABSTRACTIn keeping with the dominant view that skills are largely automatic, the standard view of memory systems distinguishes between a representational declarative system associated with cognitive processes and a performance-based procedural system. The procedural system is thought to be largely responsible for the performance of well-learned skilled actions. Here we argue that most skills do not fully automate, which entails that the declarative system should make a substantial contribution to skilled performance. To support this view, we review evidence showing that (...) the declarative system does indeed play a number of roles in skilled action. (shrink)

Reflection on the fine-grained information required for visual guidance of action has suggested that visual content is non-conceptual. I argue that in a common type of visually guided action, namely the use of manipulable artefacts, vision has conceptual content. Specifically, I show that these actions require visual attention and that concepts are involved in directing attention. In acting with artefacts, there is a way of doing it right as determined by the artefact’s conventional use. Attention must reflect our understanding of (...) the function and appropriate ways to use these artefacts, understanding that requires possession of the relevant concept. As a result, we attend to the artefact’s relevant functional properties. In these cases, attention is structured by concepts. This discussion has a bearing on the dual visual stream hypothesis. While it is often held that the two visual streams are functionally independent, the argument of this essay is that the constraints on attention suggest a functional interaction between them.

Recent work on the mechanisms underlying auditory verbal hallucination (AVH) has been heavily informed by self-monitoring accounts that postulate defects in an internal monitoring mechanism as the basis of AVH. A more neglected alternative is an account focusing on defects in auditory processing, namely a spontaneous activation account of auditory activity underlying AVH. Science is often aided by putting theories in competition. Accordingly, a discussion that systematically contrasts the two models of AVH can generate sharper questions that will lead to (...) new avenues of investigation. In this paper, we provide such a theoretical discussion of the two models, drawing strong contrasts between them. We identify a set of challenges for the self-monitoring account and argue that the spontaneous activation account has much in favor of it and should be the default account. Our theoretical overview leads to new questions and issues regarding the explanation of AVH as a subjective phenomenon and its neural basis. Accordingly, we suggest a set of experimental strategies to dissect the underlying mechanisms of AVH in light of the two competing models. (shrink)

We develop a functional abstraction principle for the type-free algorithmic logic introduced in our earlier work. Our approach is based on the standard combinators but is supplemented by the novel use of evaluation trees. Then we show that the abstraction principle leads to a Curry fixed point, a statement C that asserts C ⇒ A where A is any given statement. When A is false, such a C yields a paradoxical situation. As discussed in our earlier work, this situation leaves (...) one no choice but to restrict the use of a certain class of implicational rules including modus ponens. (shrink)

Much work on the sense of agency has focused either on abnormal cases, such as delusions of control, or on simple action tasks in the laboratory. Few studies address the nature of the sense of agency in complex natural settings, or the effect of skill on the sense of agency. Working from 2 case studies of mountain bike riding, we argue that the sense of agency in high-skill individuals incorporates awareness of multiple causal influences on action outcomes. This allows fine-grained (...) differentiation of the contributions of self and external factors to action outcomes. We further argue that the sense of agency incorporates prospective awareness of actions that are possible in a situation and awareness of the limits of control. These forms of sense of agency enable highly flexible, context-sensitive strategic control, and are likely to contribute to high interindividual variability in responses to complex tasks. (shrink)

It has often been said that 'desire' is ambiguous. I do not believe the case for this has been made thoroughly enough, however. The claim typically occurs in the course of defending controversial philosophical theses, such as that intention entails desire, where it tends to look ad hoc. There is need, therefore, for a thorough and single-minded exploration of the ambiguity. I believe the results will be more profound than might be suspected.

One important test of adequacy for a theory of welfare is completeness. To be complete a theory must cover ill-being as well as well-being. Call this the ill-being test for a theory. The author’s aim in this article is to determine how well equipped the leading theories of welfare are to pass this test. The author reaches three modest conclusions: passing the test is not straightforward for any theory; on the whole, subjective theories do better than objective ones; within the (...) subjective category experiential theories do better than desire theories.
