Research over the past half century has produced extensive evidence that observers cannot report or retain all of the details of their visual world from one moment to the next. During the past decade, a new set of studies has illustrated just how pervasive these limits are. For example, early evidence for the failure to detect changes to simple dot patterns (Phillips, 1974) and arrays of letters (Pashler, 1988) generalizes to more naturalistic displays such as photographs and motion pictures (e.g., (...) Levin & Simons, 1997; Rensink, O’Regan, & Clark, 1997; see Rensink, 2002 for a recent review). This failure to report changes (change blindness) can be induced in both simple and naturalistic displays, whenever the change co-occurs with a visual disruption such as an eye movement (Currie, McConkie, Carlson-Radvansky, & Irwin, 1995; Hollingworth, Schrock, & Henderson, 2001), image shift (Blackmore, Brelstaff, Nelson, & Troscianko, 1995), flashed blank screen (Rensink et al., 1997), blink (O’Regan, Deubel, Clark, & Rensink, 2000), transient (O’Regan, Rensink, & Clark, 1999; Rensink, O’Regan, & Clark, 2000), movie cut or pan (Levin & Simons, 1997; Simons, 1996), or an occlusion event (Levin, Simons, Angelone, & Chabris, 2002; Simons & Levin, 1998). Change blindness can also occur in the absence of a disruption, provided the change occurs gradually enough that it does not attract attention (Simons, Franconeri, & Reimer, 2000). -/- Failures of visual awareness have been induced in a number of ways. For example, observers often fail to report a visible but unexpected stimulus when attention is focused on some other object or event in the display (inattentional blindness). As for change blindness, inattentional blindness occurs for both simple (Mack & Rock, 1998; Most et al., 2001) and naturalistic stimuli (Simons & Chabris, 1999). Similarly, repeated instances of an item often go undetected when embedded in a rapid sequence (repetition blindness), a phenomenon that occurs for both words and pictures (Kanwisher, 1987; Kanwisher & Potter, 1990). Observers can also fail to detect a stimulus in a rapid stream of stimuli provided they had to perform an attention-demanding task shortly before the stimulus appeared (Shapiro, Arnell, & Raymond, 1997). The surprisingly large variety of conditions that induce failures of conscious perception reinforces the broad conclusion that we are often unaware of what would otherwise be fully-visible stimuli. -/- Along with an increased appreciation of the limitations of visual awareness has come a renewed interest in using these limitations to explore the nature of the representations and processes underlying our visual experience. Are these limitations due to failures of perception? Of attention? Of memory? What is preserved with and without awareness? -/- The papers in this special issue of the Journal of Vision provide examples of exciting new work on induced failures of visual awareness and the mechanisms that underlie them. For example, several papers examine whether observers are drawn to parts of a display by the stimulus features or whether top-down control or semantic comprehension influence search through a display. Others investigate the nature of and limits on the information that is preserved from one view to the next and how much information needs to be retained for effective perception and action. As guest editors, we hope that this special issue will illustrate how studying the relationship between visual awareness and visual representations can lead to important new insights into the nature of seeing.

The process-dissociation procedure was used to estimate the influence of spatial and form-based processing in the Simon task. Subjects made manual responses to the direction of arrows . The results provide evidence that the form and spatial location of a single stimulus can have functionally independent effects on performance. They also indicate the existence of two kinds of automaticity—an associative component that reflects prior S-R mappings and a nonassociative component that reflects the correspondence between stimulus and response codes.

Kinematic properties of reaching movements reflect constraints imposed on the joint angles. Contemporary models present solutions to the redundancy problem by a pseudoinverse procedure (Whitney 1969) or without any inversion (Berkenblit et al. 1986). Feldman & Levin suggest a procedure based on a regular inversion. These procedures are considered as an outcome of a more general approach.

Recently, a number of experiments have emphasized the degree to which subjects fail to detect large changes in visual scenes. This finding, referred to as “change blindness,” is often considered surprising because many people have the intuition that such changes should be easy to detect. Levin, Momen, Drivdahl, and Simons documented this intuition by showing that the majority of subjects believe they would notice changes that are actually very rarely detected. Thus subjects exhibit a metacognitive error we refer to as (...) “change blindness blindness.” Here, we test whether CBB is caused by a misestimation of the perceptual experience associated with visual changes and show that it persists even when the pre- and postchange views are separated by long delays. In addition, subjects overestimate their change detection ability both when the relevant changes are illustrated by still pictures, and when they are illustrated using videos showing the changes occurring in real time. We conclude that CBB is a robust phenomenon that cannot be accounted for by failure to understand the specific perceptual experience associated with a change. (shrink)

John Stuart Mill's best-known work is On Liberty. In it he declared that Western society was in danger of coming to a standstill. This was an extraordinarily pessimistic claim in view of Britain's global dominance at the time and one that has been insufficiently investigated in the secondary literature. The wanting model was that of China, a once advanced civilization that had apparently ossified. To understand how Mill came to this conclusion requires one to investigate his notion of the stages (...) from barbarism to civilization, and also his belief in imperialism as part of the civilizing process. Here India plays a central role, as both Mill and his father worked for the East India Company. This study, then, investigates the relationship between Mill's liberalism and his justification of imperialism. It takes us into the Utilitarianism of his family background, and such other influences as Romanticism, Scottish political economy and such key French thinkers as Saint- Simon, Guizot, Comte and Tocqueville. Mill, then, provides the focus of a debate on the origins, meaning, and consequences of Western civilization. It encompasses discourses on colonialism and orientalism, on Enlightenment optimism and conservative despair, on the need for leadership and the advance of democracy; in short, on the blessings, curses and dangers of modernization from approximately the time of the American and French revolutions to that of the so-called mid-Victorian calm in which On Liberty was written. Furthermore, current political issues concerning the West and Islamic countries have heightened interest in just the kind of question that this book discusses: that of how the West relates to, and assesses, the rest of the world.

_On Heidegger's Being and Time_ is an outstanding exploration of Heidegger's most important work by two major philosophers. Simon Critchley argues that we must see _Being and Time_ as a radicalization of Husserl's phenomenology, particularly his theories of intentionality, categorial intuition, and the phenomenological concept of the a priori. This leads to a reappraisal and defense of Heidegger's conception of phenomenology. In contrast, Reiner Schürmann urges us to read Heidegger 'backward', arguing that his later work is the key to (...) unravelling _Being and Time_. Through a close reading of _Being and Time_ Schürmann demonstrates that this work is ultimately aporetic because the notion of Being elaborated in his later work is already at play within it. This is the first time that Schürmann's renowned lectures on Heidegger have been published. The book concludes with Critchley's reinterpretation of the importance of authenticity in _Being and Time_. Arguing for what he calls an 'originary inauthenticity', Critchley proposes a relational understanding of the key concepts of the second part of _Being and Time_: death, conscience and temporality.

A hierarchical ordering of approaches afflicts environmental thinking. An ethics of individualism unjustly overrides social/political philosophy in environmental debates. Dialectics helps correct this imbalance. In dialectical fashion, a synthesis emerges between conflicting approaches to dialectics and to nature from: Marxism (Levins and Lewontin), anarchism (Bookchin), and Native Americanism (Black Elk). Conflicting (according to Marxists) and cooperative (according to anarchists) forces both operate in nature. Ethics (anarchist), political theory (Marxist), and spirituality (Native American) constitute the interconnected interpretative domains of a dialectically (...) informed ecophilosophy. In a world painted too often in blacks and whites, ecological dialectics colors the picture a more realistic gray. (shrink)

Interventions that are designed to stem plagiarism do not always override the motivation of individuals to cheat and, therefore, may not diminish misconduct. To inform more effective approaches, we conducted a systematic review to clarify the psychological causes of plagiarism. This review of 83 empirical papers showed that a specific blend of circumstances may foster plagiarism: an emphasis on competition and success rather than development and cooperation coupled with impaired resilience, limited confidence, impulsive tendencies, and biased cognitions. Fortunately, whenever students (...) feel their life and studies align to their future aspirations, many of these circumstances tend to dissipate. (shrink)

Prompted by a recommendation of the two Christian hospital associations in Germany, the Neu-Mariahilf Hospital in Goettingen set up a health ethics committee in autumn 1998. It is the committee's task to give support to staff members, patients and their relatives in individual cases where ethical dilemmas arise. The following article descibes the committee's work by means of three cases.

Clarke and Beck assume that approximate number system representations should be assigned referents from our scientific ontology. However, many representations, both in perception and cognition, do not straightforwardly refer to such entities. If we reject Clarke and Beck's assumption, many possible contents for ANS representations besides number are compatible with the evidence Clarke and Beck cite.

Recent influential accounts of temporal representation—the use of mental representations with explicit temporal contents, such as before and after relations and durations—sharply distinguish representation from mere sensitivity. A common, important picture of inter-temporal rationality is that it consists in maximizing total expected discounted utility across time. By analyzing reinforcement learning algorithms, this article shows that, given such notions of temporal representation and inter-temporal rationality, it would be possible for an agent to achieve inter-temporal rationality without temporal representation. It then explores (...) potential upshots of this result for theorizing about rationality and representation. (shrink)

It is often claimed by environmental philosophers and green political theorists that liberalism, the dominant tradition of western political philosophy, is too focused on the interests of human individuals to give due weight to the environment for its own sake. In "How to be a Green Liberal", Simon Hailwood challenges this view and argues that liberalism can embrace a genuinely 'green', non-instrumental view of nature. The book's central claim is that nature's 'otherness', its being constituted of independent entities and (...) processes that do not reflect our purposes, is a basis for value and can be incorporated within liberal political philosophy as a fundamental commitment alongside human freedom and equality. Hailwood argues that the conceptual resources already exist within mainstream liberalism for a thoroughly non-instrumental perspective. Adopting a rigorous philosophical approach Hailwood tackles a wide range of themes across environmental ethics, including holistic theories, deep ecology, eco-feminism and eco-anarchism, as well as issues in value theory and political philosophy more generally. In making the case for liberalism's green credentials "How to be a Green Liberal" is a formidable challenge to recent green political theory and will be required reading not only for students of political philosophy but for all those interested in the natural world and man's relationship to it.

This essay articulates a double helix at work in Badiou’s thought on politics as a condition of philosophy and philosophy as such by focusing on what Badiou calls “the Idea of communism” and we will call “the communism of the Idea.” The former refers to communism as an Idea par excellence, while the latter concerns the Idea as a philosophical communism. The first section of the essay unpacks the Idea of communism as a composite interaction of politics, history, and subjectivity (...) insofar as each of these elements cannot be taken in themselves. Contrary to post-ideology, Badiou condemns the claim that we should live without an ideological framework insofar as this asks us to live without an Idea. The second section will focus on the communism of the Idea as the result of Badiou’s broader philosophical project and its major Platonic gestures. Badiou’s broader concerns pertain to the commitment to live with an Idea as finite, infinite, and transfinite to the endpoint that philosophy itself is characterized to be destined for communism. The crux that anyone can become a serious philosopher if, to paraphrase Diotima in Plato’s Symposium, they gracefully lend themselves to the process of truths as their fundamental commitment.

It is widely supposed that liberal political theory must exclude direct concern for nature, that its anthropocentric individualism can allow only indirect, instrumental value to the non‐human world. This is perhaps thought to be especially true of contractarian versions of liberalism. In this paper I try to show that this is not so by outlining an argument based on an analogy between the ‘neutrality’ of Rawls' political liberalism and the ‘otherness’ of external nature. I consider some possible objections to the (...) argument, and try to explain why I think that the analogy is strong enough to justify modifying the Rawlsian approach to encompass direct concern for external nature (as other). If I am right then it is not necessary completely to abandon that approach in order to construct a more adequately ecocentric political theory. (shrink)

In this paper I address the issue of how far libertarianism can serve as the theoretical framework for a political morality excluding serious obligations to the needy. This issue has been raised recently by Gillian Brock who argues that even those adopting a thoroughgoing libertarianism, such as that of Robert Nozick, must recognise significant obligations to the needy as a condition of claiming exclusive property rights. I argue that Brock fails to demonstrate this. After briefly describing Brock's main argument I (...) discuss the acquisition of libertarian property rights, and try to show there are sufficient resources in Nozick's account for him to accept her main conclusion in principle without recognising significant obligations. Then, after some supplementary discussion, I sketch two different lines of argument. One uses the issue of corporate liability. The other focusses on problems with Nozick's "entitlement" principle of rectification. I try to show that even if the libertarian entitlement theory of property rights, their acquisition and transfer, is accepted, this gives no grounds for resisting claims for redistribution based on others' needs.

We study the minimal complexity of tilings of a plane with a given tile set. We note that every tile set admits either no tiling or some tiling with.

This book examines the general liberal aspiration of neutrality whilst moving discussion of Nozick's moral and political philosophy on from Anarchy, State and Utopia. Using neutralism as a unifying theme it connects his views on ethics, value and pluralism with the earlier libertarianism, combining an up to date critique of Nosick with a fresh view of neutrality.

Japanese Frames of Mind addresses two main questions in light of a collection of research conducted by both Japanese and American researchers at Harvard University: What challenge does Japanese psychology offer to Western psychology? Will the presumed universals of human nature discovered by Western psychology be reduced to a set of 'local psychology' among many in a world of unpredicted variations? The chapters provide a wealth of new data and perspectives related to aspects of Japanese child development, moral reasoning and (...) narratives, schooling and family socialization, and adolescent experiences. By placing the Japanese evidence within the context of Western psychological theory and research, the book calls for a systematic reexamination of Western psychology as one psychology among many other ethnopsychologies. Written in mostly non-technical language, this book will appeal to developmental and cultural psychologists, anthropologists interested in psychological anthropology, educators, and anyone interested in Japanese and Asian studies.

Our studies of naturally occurring human dialogue have led to the recognition of a class of regularities which characterize impoltant aspects of communication. People appear to interact according to established patterns which span several turns in a dialogue and which recur frequently. These patterns appear to be organized around the goals which the dialogue serves for each participant. Many things which are said later in a dialogue can only be interpreted as pursuit of these goals, established by earlier dialogue.These patterns (...) have been represented b) a set of knowledge structures called Dialogue‐Games, capturing shared, conventional knowledge that people have about communication and how it can be used to achieve goals. A Dialogue‐Game has Parameters, which represent those elements that vary across instances of a particular pattern‐the particular dialogue participants and the content topic. The states of the world which must be in effect for a particular Dialogue‐Game to be employed successfully are represented by Specifications of these Parameters. Finally, the expected sequence of intermediate states that occur during instances of a particular conventional pattern are represented by the Components of the corresponding Dialogue‐Game.Representations for several Dialogue‐Games are presented here, based on our analyses of different kinds of naturally occurring dialogue. A process model is discussed, showing Dialogue‐Game identification, pursuit, and termination as part of the comprehension of dialogue utterances. This Dialogue‐Game model captures some of the important functional aspects of language, especially indirect uses to achieve implicit communication. (shrink)

We show that the variety of n -dimensional weakly higher order cylindric algebras, introduced in Németi [9], [8], is finitely axiomatizable when n > 2. Our result implies that in certain non-well-founded set theories the finitization problem of algebraic logic admits a positive solution; and it shows that this variety is a good candidate for being the cylindric algebra theoretic counterpart of Tarski’s quasi-projective relation algebras.

The participation of physicians in the atrocities of the Holocaust exposed vulnerabilities in medicine’s moral commitment to patients’ best interests that every health professional should recognize. Teaching about this history is challenging, as it is extremely complex and there are no common standards for what basic historical facts students in health professions training programs should learn. Nor is there guidance on how these historical facts can or should be related to contemporary ethical issues facing health professionals. To address these problems, (...) we propose a set of core historical facts about health professional involvement in the Holocaust that every student in a health professional training program should learn. We then identify three ethical lessons from the Holocaust that are pertinent today as physicians struggle to maintain their moral compass and earn the trust of patients and the public: 1) The lesson of commitment to science; maintaining balance between reason and skepticism in the search for truth, The lesson of clinical detachment; maintaining balance between necessary professional distance with a commitment to humanism and intimacy with patients, and 3) The lesson of competing loyalties; maintaining balance in upholding medicine’s multiple responsibilities, including to individual patients and the larger community. Embedding these facts and lessons into the education of health professionals is challenging yet critically important. Today’s physicians struggle with some of the same ethical tensions as did German physicians in the Nazi era, albeit in a much-attenuated fashion. Awareness of these tensions and taking active measures to maintain them in balance are necessary components of humanistic health care, which should be an integral part of health professional training programs.
