When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

The United States Fish and Wildlife Service in Alaska, USA, conducted a species status assessment for a petition to list the Alexander Archipelago wolf (Canis lupus ligoni) under the Endangered Species Act in 2020-2022. This federal undertaking could not be adequately prepared without including the knowledge of Indigenous People who have a deep cultural connection with the subspecies. Our objective is to communicate the authoritative expertise and voice of the Indigenous People who partnered on the project by demonstrating how their (...) knowledge contributed to the species status assessment. The Indigenous knowledge applied in the assessment is the cultural and intellectual property of those who have shared it. We employed rapid appraisal research to expeditiously develop a preliminary and qualitative understanding of Indigenous People's cultural and ecological knowledge of Alexander Archipelago wolves. We used semi-directed interviewing and inductive coding from grounded theory for text analysis. Indigenous knowledge contributed to the agency's understanding of the Alexander Archipelago wolf in Southeast Alaska and helped the agency with their classification decision. Indigenous research partners explained the rich cultural significance and position of wolves in Tlingit society and described human–wolf relationships and ecological interactions. The agency used a single-species assessment approach based in species ecology and conservation biology, whereas the Indigenous wolf experts applied a multi-species, community ecology approach based in a sociocultural context of balance and respect. The Indigenous wolf experts successfully addressed knowledge gaps identified by the agency. The partners were challenged by a short regulatory timeframe that did not allow for comprehensive study of Indigenous knowledge and constrained review and feedback by Indigenous experts. The United States Fish and Wildlife Service learned that its assessment framework was not designed to account for an Indigenous worldview. To level the playing field, the agency and Indigenous experts should discuss how to co-develop an assessment framework that equitably applies both perspectives. (shrink)

Essentialism is widely regarded as a mistaken view of biological kinds, such as species. After recounting why (sections 2-3), we provide a brief survey of the chief responses to the “death of essentialism” in the philosophy of biology (section 4). We then develop one of these responses, the claim that biological kinds are homeostatic property clusters (sections 5-6) illustrating this view with several novel examples (section 7). Although this view was first expressed 20 years ago, and has received recent discussion (...) and critique, it remains underdeveloped and is often misrepresented by its critics (section 8). (shrink)

One of the more powerful impressions created by vision is that of a coherent, richly-detailed world where everything is present simultaneously. Indeed, this impression is so compelling that we tend to ascribe these properties not only to the external world, but to our internal representations as well. But results from several recent experiments argue against this latter ascription. For example, changes in images of real-world scenes often go unnoticed when made during a saccade, flicker, blink, or movie cut. This "change (...) blindness" provides strong evidence against the idea that our brains contain a picture-like representation of the scene that is everywhere detailed and coherent. (shrink)

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, in particular, whether colors are any of the (...) properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

The emphasis on the limitations of objectivity, in specific guises and networks, has been a continuing theme of contemporary analytic philosophy for the past few decades. The popular sport of baiting feminist philosophers — into pointing to what's left out of objective knowledge, or into describing what methods, exactly, they would offer to replace the powerful objective methods grounding scientific knowledge — embodies a blatant double standard which has the effect of constantly putting feminist epistemologists on the defensive, on the (...) fringes, on the run.This strategy can only work if objectivity is transparent, simple, stable, and clear in its meaning. It most certainly is not. In fact, taking objectivity as a sort of beautiful primitive, self-evident in its value, and all-powerful in its revelatory power, requires careless philosophy, and the best workers in metaphysics, epistemology, and philosophy of science have made reworked definitions of objectivity absolutely central to their own projects. In fact, classic feminist concerns with exploring the impact of sex and gender on knowledge, understanding, and other relations between human beings and the rest of the world fall squarely within the sort of human and social settings thatare already considered central in most current analytic metaphysics, epistemology, and philosophy of science. I argue that the burden of proof is clearly on those who wish toreject the centrality and relevance of sex and gender to our most fundamental philosophical work on knowledge and reality. (shrink)

While memory is conceptualized predominantly as an individual capacity in the cognitive and biological sciences, the social sciences have most commonly construed memory as a collective phenomenon. Collective memory has been put to diverse uses, ranging from accounts of nationalism in history and political science to views of ritualization and commemoration in anthropology and sociology. These appeals to collective memory share the idea that memory ‘‘goes beyond the individual’’ but often run together quite different claims in spelling out that idea. (...) This paper reviews a sampling of recent work on collective memory in the light of emerging externalist views within the cognitive sciences, and through some reflection on broader traditions of thought in the biological and social sciences that have appealed to the idea that groups have minds. The paper concludes with some thoughts about the relationship between these kinds of cognitive metaphors in the social sciences and our notion of agency. (shrink)

Discussions of whistleblowing and employee loyalty usually assume either that the concept of loyalty is irrelevant to the issue or, more commonly, that whistleblowing involves a moral choice in which the loyalty that an employee owes an employer comes to be pitted against the employee''s responsibility to serve public interest. I argue that both these views are mistaken and propose a third view which sees whistleblowing as entirely compatible with employee loyalty.

This paper examines the standard view of realization operative incontemporary philosophy of mind, and proposes an alternative, generalperspective on realization. The standard view can be expressed, insummary form, as the conjunction of two theses, the sufficiency thesis andthe constitutivity thesis. Physicalists of both reductionist and anti-reductionist persuasions share a conception of realization wherebyrealizations are determinative of the properties they realize and physically constitutive of the individuals with those properties. Centralto the alternative view that I explore here is the idea that (...) the requisite,metaphysically robust notion of realization is ineliminably context-sensitive. I shall argue that the sufficiency and constitutivity theses aretypically not jointly satisfied by any one candidate realizer, and that goingcontext-sensitive in one's metaphysics is preferable to the standard view.The context-sensitive views developed here are implicit in a range ofcommon views in both the philosophy of mind and the philosophy of biology,even if they have not been explicitly articulated, and even though theyundermine other views that are commonly endorsed.

When natural selection theory was presented, much active philosophical debate, in which Darwin himself participated, centered on its hypothetical nature, its explanatory power, and Darwin's methodology. Upon first examination, Darwin's support of his theory seems to consist of a set of claims pertaining to various aspects of explanatory success. I analyze the support of his method and theory given in the Origin of Species and private correspondence, and conclude that an interpretation focusing on the explanatory strengths of natural selection theory (...) accurately reflects neither Darwin's own self-consciously held views, nor the nature of his support. Darwin's methodological and philosophical arguments were at once consistently empiricist and more sophisticated than such interpretations credit to him. (shrink)

I suggest following Paul Feyerabend's own advice, and interpreting Feyerabend's work in light of the principles laid out by John Stuart Mill. A review of Mill's essay, On Liberty, emphasizes the importance Mill placed on open and critical discussion for the vitality and progress of various aspects of human life, including the pursuit of scientific knowledge. Many of Feyerabend's more unusual stances, I suggest, are best interpreted as attempts to play certain roles--especially the role of "defender of unpopular minority opinion"--that (...) are necessary to fulfilling Mill's conditions for rational exchange and optimal human development.

This paper attempts to do two things. First, it recounts the problem of intentionality, as it has typically been conceptualized, and argues that it needs to be reconceptualized in light of the radical form of externalism most commonly referred to as the extended mind thesis. Second, it provides an explicit, novel argument for that thesis, what I call the argument from meaning making, and offers some defense of that argument. This second task occupies the core of the paper, and in (...) completing it I distinguish _active _ _cognition_ from _cyborg fantasy arguments_ for externalism, and develop the analogy between the extended mind thesis in the cognitive sciences and developmental systems theory in developmental biology. The rethinking of the problem of intentionality on offer leads not so much to a solution as to a dissolution of that problem, as traditionally conceived. (shrink)

We introduce two notions–the shadows and the shallows of explanation–in opening up explanation to broader, interdisciplinary investigation. The shadows of explanation refer to past philosophical efforts to provide either a conceptual analysis of explanation or in some other way to pinpoint the essence of explanation. The shallows of explanation refer to the phenomenon of having surprisingly limited everyday, individual cognitive abilities when it comes to explanation. Explanations are ubiquitous, but they typically are not accompanied by the depth that we might, (...) prima facie, expect. We explain the existence of the shadows and shallows of explanation in terms of there being a theoretical abyss between explanation and richer, theoretical structures that are often attributed to people. We offer an account of the shallows, in particular, both in terms of shorn-down, internal, mental machinery, and in terms of an enriched, public symbolic environment, relative to the currently dominant ways of thinking about cognition and the world.

This paper is a critique of some ideas about narrow content owing to Horgan and Tienson and Brian Loar.

It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or sense) the change even though they have no visual experience of it. The (...) subjective difference between sensing and seeing is mirrored in several behavioral differences, suggesting that these are two distinct modes of conscious visual perception. (shrink)

This paper examines a recent, influential argument for individualism in psychology defended by Jerry Fodor and others, what I call the argument from causal powers. I argue that this argument equivocates on the crucial notion of "causal powers", and that this equivocation constitutes a deep problem for arguments of this type. Relational and individualistic taxonomies are incompatible, and it does not seem in general to be possible to factor the former into the latter. The distinction between powers and properties plays (...) a central role in my argument. (shrink)

David Sloan Wilson has recently revived the idea of a group mind as an application of group selectionist thinking to cognition. Central to my discussion of this idea is the distinction between the claim that groups have a psychology and what I call the social manifestation thesis-a thesis about the psychology of individuals. Contemporary work on this topic has confused these two theses. My discussion also points to research questions and issues that Wilson's work raises, as well as their connection (...) to externalist conceptions of the mind familiar since the work of Putnam and Burge.

When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: the changes become extremely difficult to notice, even when they are large, presented repeatedly, and the observer expects them to occur (Rensink, O'Regan, & Clark, 1997). To determine the mechanisms behind this induced "change blindness", four experiments examine its dependence on initial preview and on the nature of the interruptions used. Results support the proposal that representations at (...) the early stages of visual processing are highly volatile, and that focused attention is needed to stabilize them sufficiently to support the perception of change.

In this paper I distinguish various ways in which empirical claims about evolutionary and ecological models can be supported by data. I describe three basic factors bearing on confirmation of empirical claims: fit of the model to data; independent testing of various aspects of the model, and variety of evident. A brief description of the kinds of confirmation is followed by examples of each kind, drawn from a range of evolutionary and ecological theories. I conclude that the greater complexity and (...) precision of my approach, as compared to, for instance, a Popperian approach, can facilitate detailed analysis and comparison of empirical claims.

Doctors must now take a fifth vital sign from their patients: pain reports. I use this as a case study to discuss how different schools of psychology (introspectionism, behaviorism, cognitive psychology) have treated verbal reports about the contents of consciousness. After examining these differences, I suggest that, with new methods of mapping data about neurobiological states with behavioral data and with verbal reports about conscious experience, we should reconsider some of the introspectionists' goals and methods. I discuss examples from cognitive (...) psychology, including pain researchers' attempts to develop self-reports of pain so that they can be, like other vital signs, reliable indicators of internal states.

I argue that partialist critics of deontological theories make a mistake similar to one made by critics of utilitarianism: they fail to distinguish between a theory’s decision procedure and its standard of rightness. That is, they take these deontological theories to be offering a method for moral deliberation when they are in fact offering justificatory arguments for moral principles. And while deontologists, like utilitarians do incorporate impartiality into their justifications for basic principles, many do not require that agents utilize impartial (...) methods of moral deliberation. It follows that insofar as partialists reject impartiality in deliberation, their criticisms may miss their mark. If however, partialists are opposed to justifications for basic principles that rely upon impartiality, they are committed, I argue, to drastic revisions in moral theory that have worrisome implications.

Most models of generational succession in sexually reproducing populations necessarily move back and forth between genic and genotypic spaces. We show that transitions between and within these spaces are usually hidden by unstated assumptions about processes in these spaces. We also examine a widely endorsed claim regarding the mathematical equivalence of kin-, group-, individual-, and allelic-selection models made by Lee Dugatkin and Kern Reeve. We show that the claimed mathematical equivalence of the models does not hold. *Received January 2007; revised (...)

In Vagueness and Contradiction (2001), Roy Sorensen defends and extends his epistemic account of vagueness. In the process, he appeals to connections between vagueness and semantic paradox. These appeals come mainly in Chapter 11, where Sorensen offers a solution to what he calls the no-no paradox—a “neglected cousin” of the more famous liar—and attempts to use this solution as a precedent for an epistemic account of the sorites paradox. This strategy is problematic for Sorensen’s project, however, since, as we establish, (...) he fails to resolve the semantic pathology of the no-no paradox. (shrink)

Three theories contend as explanations of perpetrator behavior in the Holocaust as well as other cases of genocide: structural, intentional, and situational. Structural explanations emphasize the sense in which no single individual or choice accounts for the course of events. In opposition, intentional/cutltural accounts insist upon the genocides as intended outcomes, for how can one explain situations in which people ‘step up’ and repeatedly kill defenseless others in large numbers over sustained periods of time as anything other than a choice? (...) Situational explanations offer a type of behavioral account; this is how people act in certain environments. Critical to the situational account as I discuss it is the ‘Asch paradigm’, i.e. experimentally attested conditions for eliciting conformityof behavior regardlesss of available evidence of prior beliefs. In what follows, I defend what I term above a version of situational explanations of perpetrator behavior. Moreover, I maintain that the factors that explain provide an understanding as well. While not committed to the complete irrelevance or exclusion of cultural or structural factors, nonetheless situational analyses can account both for what happened and why. A cardinal virtue of this version of situational explanations consists in showing how shallow the problem of understanding turns out to be for such cases. (shrink)

We show that cast shadows can have a significant influence on the speed of visual search. In particular, we find that search based on the shape of a region is affected when the region is darker than the background and corresponds to a shadow formed by lighting from above. Results support the proposal that an early-level system rapidly identifies regions as shadows and then discounts them, making their shapes more difficult to access. Several constraints used by this system are mapped (...) out, including constraints on the luminance and texture of the shadow region, and on the nature of the item casting the shadow. Among other things, this system is found to distinguish between line elements (items containing only edges) and surface elements (items containing visible surfaces), with only the latter deemed capable of casting a shadow.

In her recent book Persons and Bodies1, Lynne Rudder Baker has defended what she calls the constitution view of persons. On this view, persons are constituted by their bodies, where “constitution” is a ubiquitous, general metaphysical relation distinct from more familiar relations, such as identity and part-whole composition.

Several studies (e.g., Becklen & Cervone, 1983; Mack & Rock, 1998; Neisser & Becklen, 1975) have found that observers attending to a particular object or event often fail to report the presence of unexpected items. This has been interpreted as inattentional blindness (IB), a failure to see unattended items (Mack & Rock, 1998). Meanwhile, other studies (e.g., Pashler, 1988; Phillips, 1974; Rensink et al., 1997; Simons, 1996) have found that observers often fail to report the presence of large changes in (...) a display when these changes occur simultaneously with a transient such as an eye movement or flash of the display. This has been interpreted as change blindness (CB), a failure to see unattended changes (Rensink et al., 1997). In both cases there is a striking failure to report an object or event that would be quite visible under other circumstances. And in both cases there is a widespread (although not universal) belief that the underlying cause has to do with the absence of attention. The question then arises as to how these effects might be related. Is CB the same thing as IB? If not, what is the relation between them? And given that these phenomena deal with failures of subjective perception, what can they teach us about the nature of our visual experience? In particular, what can they teach us about the role played by visual attention? (shrink)

This paper considers the importance of play as a conventional space for hypothetical self-expression and self-trial, its importance for determination of identity, and for development of self-possibilities. Expanding such possibilities in play enables challenging of socially entrenched assumptions concerning possible and appropriate identities. Discussion is extended to the contexts of gender performance (drag) and sport-play. It is argued that play proceeds on the basis of a fundamental pretence of reality that must be taken seriously by its participants; this discussion includes (...) considerations of serious and ironical play, “playing-at”, and travesty.

A number of debates in philosophy of biology and psychology, as well as in their respective sciences, hinge on particular views about the relationship between genotypes and phenotypes. One such view is that the genotype-phenotype relationship is relatively straightforward, in the sense that a genome contains the ?genes for? the various traits that an organism exhibits. This leads to the assumption that if a particular set of traits is posited to be present in an organism, there must be a corresponding (...) number of genes in that organism's genome to account for those traits. This assumption underlies what can be called the ?counting argument,? in which empirical estimates of the number of genes in a genome are used to support or refute particular hypotheses in philosophical debates about biology and psychology. In this paper, we assess the counting argument as it is used in discussions of the alleged massive modularity of the brain, and conclude that this argument cannot be upheld in light of recent philosophical work on gene concepts and empirical work on genome complexity. In doing so, we illustrate that there are those on both sides of the debate about massive modularity who rely on an incorrect view of gene concepts and the nature of the genotype-phenotype relationship.

The social, behavioral, and a good chunk of the biological sciences concern the nature of individual agency, where our paradigm for an individual is a human being. Theories of economic behavior, of mental function and dysfunction, and of ontogenetic development, for example, are theories of how such individuals act, and of what internal and external factors are determinative of that action. Such theories construe individuals in distinctive ways.

This paper poses a problem of promiscuity for views that endorse material constitution as a metaphysic relation.

I argue that understanding the self in terms of narrative construction does not preclude the possibility of error concerning one’s own self. Identity is a projection of first and second-order desires and a product of choice in relation to desire. Self-deceit appears in this connection as a response to an identity that one has constructed through choice and/or desire but not acknowledged in one’s self-account, reflecting a conflict between desires or a motivated failure to account. This analysis is applied primarily (...) to acknowledgement of one’s sexual identity. (shrink)

One of the more compelling beliefs about vision is that it is based on representations that are coherent and complete, with everything in the visual field described in great detail. However, changes made during a visual disturbance are found to be difficult to see, arguing against the idea that our brains contain a detailed, picture-like representation of the scene. Instead, it is argued here that a more dynamic, "just-in-time" representation is involved, one with deep similarities to the way that users (...) interact with external displays. It is further argued that these similarities can provide a basis for the design of intelligent display systems that can interact with humans in highly effective and novel ways. (shrink)

Can video games or the playing of such games be morally objectionable? Many attempts to justify our intuitions about the morality of certain games or game activities are either unsuccessful or fall short. This is mainly due to a normative gap between reality and virtuality that classical approaches to moral philosophy cannot bridge. I am investigating to what extent an accurate action analysis can help us to justify our intuitions that, in some cases, something is ethically wrong with video games. (...) To do so, I am using Frankfurt’s volition theory to show how virtual game actions can be evaluated based on virtue ethics. This virtue ethical assessment is compatible with Ostritsch’s (2017) endorsement view. Especially in light of the gamification of our surroundings, the question of the ethical status of video gaming is becoming more and more urgent. By arguing that a virtue ethical approach can tell us more about the ethical aspects of video gaming, I will also argue that virtue ethics (because of similar problems in these fields) is promising regarding the ethics of simulation, art, and literature.

Fred Dretske has recently argued, in a highly original book and a series of articles, that action explanations are a very special species of historical explanation, in opposition to the traditional view that action explanations cite causes of actions, which are identical with bodily movements. His account aims to explain how it is possible for there to be a genuine explanatory role for reasons in a world of causes, and, in particular, in a world in which we have available in (...) principle an explanation for any movement of our bodies in neurophysiological terms. While Dretske draws attention to an important, and overlooked, feature of the form of the explananda of action explanations, he draws the wrong conclusion from it. This paper argues argues that his account of the nature of action explanations, and the role of reasons in explaining behavior, cannot be right. This will force us to re©examine the assumptions that suggest that reason explanations and neurophysiological explanations of our movements cannot coexist. (shrink)

Let us call a thought or belief whose content would be expressed by a sentence of subject-predicate form (by the thinker or someone attributing the thought to the thinker) an ‘ascription’. Thus, the thought that Madonna is middle-aged is an ascription of the property of being middle-aged to Madonna. To call a thought of this form an ascription is to emphasize the predicate in the sentence that gives its content. Let us call an ‘x-ascription’ an ascription whose subject is x, (...) that is, an ascription such that the subject of the sentence which would express its content is x.

At the beginning of the first book of Posterior Analytics, Aristotle‟s feature of demonstrative knowledge involves a certain concept of “necessity”. The traditional interpretation tends to associate this concept with modal necessity, which is found in the Prior Analytics and De interpretatione.

Social externalism is the view that the contents of a person's propositional attitudes are logically determined at least in part by her linguistic community's standards for the use of her words. If social externalism is correct, its importance can hardly be overemphasized. The traditional Cartesian view of psychological states as essentially first personal and non-relational in character, which has shaped much theorizing about the nature of psychological explanation, would be shown to be deeply flawed. I argue in this paper that (...) social externalism faces insuperable difficulties. The first difficulty is that if syntax and semantics are independent, then social externalism is committed to the absurd consequence that many people have beliefs with formally inconsistent contents. I argue none of the possible responses to this objection are plausible. The second difficulty is that if syntax and semantics are independent, then social externalists are committed to a contradiction. After raising and defending these objections, I identify what I think is the underlying flaw in the social externalist position, a failure to pay attention to the structure of communication intentions, and briefly indicate how to neutralize the linguistic evidence social externalists advance in favor of their view.

This essay constitutes an attempt to probe the very idea of a saying/showing distinction of the kind that Wittgenstein advances in the Tractatus—to say what such a distinction consists in, to say what philosophical work it has to do, and to say how we might be justified in drawing such a distinction.

Focused attention is needed to perceive change (Rensink et al., 1997; Psychological Science, 8: 368-373) . But how much attentional processing is given to an item? And does this depend on the nature of the task? To answer these questions, "flicker" displays were created, where an original and a modified image continually alternated, with brief blanks between them. Each image was an array of simple figures, half being horizontal and the other half vertical. In half the trials, one of the (...) items changed orientation; in the remainder, all items remained the same. Observers were asked to detect whether a change was occurring in each trial. -/- Within-observer comparisons for different shapes of items yielded two classes of speed: relatively fast search (50 ms/item) for simple lines, and slower search (90 ms/item) for compound figures made of two or more lines. Evidently, more processing was given to compound figures, even though shape was irrelevant to the task. A similar set of experiments asked observers to detect changes in contrast polarity. Here, no differences were found for different shapes, indicating that geometric information is not processed as much when the task involves only nongeometric properties. (shrink)

This paper points to some problems for the position that D.M. Walsh calls "alternative individualism," and argues that in defending this view Walsh has omitted an important part of what separates individualists and externalists in psychology. Walsh's example of Hox gene complexes is discussed in detail to show why some sort of externalism about scientific taxonomy more generally is a more plausible view than any extant version of individualism.

<The definitive version is available at www.blackwell-synergy.com > -- In this paper I carve out a space between the concept of "the object" and the seemingly endless ways in which "the object" can be represented pictorially.

I will explore this space by drawing upon theories of pictorial representation, leaving out, for the sake of my purposes here, a consideration of the (...) artist's intention. That an attribution of "style" can be comprehensive while leaving out a consideration of artists' intentions, I will argue by adopting the conceptual framework of Paul Thom's theory of interpretation. Before embarking on my project, I begin with a brief overview of the rather slippery notion of "style". (shrink)

Recent developments in vision science have resulted in several major changes in our understanding of human visual perception. For example, attention no longer appears necessary for "visual intelligence"--a large amount of sophisticated processing can be done without it. Scene perception no longer appears to involve static, general-purpose descriptions, but instead may involve dynamic representations whose content depends on the individual and the task. And vision itself no longer appears to be limited to the production of a conscious "picture"--it may also (...) guide processes outside the conscious awareness of the observer. (shrink)

According to Field’s influential incompleteness objection, Tarski’s semantic theory of truth is unsatisfactory since the definition that forms its basis is incomplete in two distinct senses: (1) it is physicalistically inadequate, and for this reason, (2) it is conceptually deficient. In this paper, I defend the semantic theory of truth against the incompleteness objection by conceding (1) but rejecting (2). After arguing that Davidson and McDowell’s reply to the incompleteness objection fails to pass muster, I argue that, within the constraints (...) of a non-reductive physicalism and a holism concerning the concepts of truth, reference and meaning, conceding Field’s physicalistic inadequacy conclusion while rejecting his conceptual deficiency conclusion is a promising reply to the incompleteness objection.

If we conceive of ourselves as animals, it might be accurate to call us visual animals. The visual cortex is much larger in us relative to the size of our brains than in other animals, and large relative to the parts of the cortex responsible for the transmission of signals emanating from the other perceptual transducers. Our ability to recall visual images, recombine them in imagination and enter imaginatively into narratives is linked to this evolved piece of brain architecture. However, (...) what this means within the context of human culture is not so clear. A large visual cortex might not necessarily translate into a heightened susceptibility for fine visual distinctions over auditory or kinetic distinctions, at least not in all cultural contexts.

In the good old days, when general philosophy of science ruled the Earth, a simple division was often invoked to talk about philosophical issues specific to particular kinds of science: that between the natural sciences and the social sciences. Over the last 20 years, philosophical studies shaped around this dichotomy have given way to those organized by more fine-grained categories, corresponding to specific disciplines, as the literatures on the philosophy of physics, biology, economics and psychology--to take the most prominent four (...) examples--have blossomed. In general terms, work in each of these areas has become increasingly enmeshed with that in the corresponding science itself, increasingly naturalistic (in at least one sense of that term), and in my view, increasingly interesting.

Third-party property insurance (TPPI) protects insured drivers who accidentally damage an expensive car from the threat of financial ruin. Perhaps more importantly though, TPPI also protects the victims whose losses might otherwise go uncompensated. Ought responsible drivers therefore take out TPPI? This paper begins by enumerating some reasons for why a rational person might believe that they have a moral obligation to take out TPPI. It will be argued that if what is at stake in taking responsibility is the ability (...) to compensate our possible future victims for their losses, then it might initially seem that most people should be thankful for the availability of relatively inexpensive TPPI because without it they may not have sufficient funds to do the right thing and compensate their victims in the event of an accident. But is the ability to compensate one's victims really what is at stake in taking responsibility? The second part of this paper will critically examine the arguments for the above position, and it will argue that these arguments do not support the conclusion that injurers should compensate their victims for their losses, and hence that drivers need not take out TPPI in order to be responsible. Further still, even if these arguments did support the conclusion that injurers should compensate their victims for their losses, then (perhaps surprisingly) nobody should to be allowed to take out TPPI because doing so would frustrate justice.
