The results of two experiments provide the first direct demonstration that subjects can process a word lexically despite concurrently being engaged in decoding a task cue telling them which of two tasks to perform. These results, taken together with others, point to qualitative differences between the mind‘s ability to engage in lexical versus sublexical processing during the time they are engaged with other tasks. The emerging picture is one in which some form of resource plays little role during lexical processing (...) whereas the need for some form of resource during sublexical processing serves to bottleneck performance.

Must readers intend to process a word to activate various levels of representation, or is such processing simply triggered by the presentation of a word ? This issue was addressed via the use of Besner and Care’s Task Set paradigm. On each trial a cue, which indicated which of two tasks to perform appeared either before the target, or at the same time as the target. If subjects can process the target while preparing a task set, then the effect (...) of a manipulated psycholinguistic factor should be absorbed into the time taken to process the cue. Despite robust main effects of SOA and word frequency there was no interaction between these factors when the task was to read aloud. This result implies that target processing is delayed until the subject knows what task to perform, and therefore that intention plays an important role when reading words aloud. (shrink)

By hypothesis, awareness is involved in the modulation of feedback from semantics to the lexical level in the visual word recognition system. When subjects are aware of the fact that there are many related prime–target pairs in a semantic priming experiment, this knowledge is used to configure the system to feed activation back from semantics to the lexical level so as to facilitate processing. When subjects are unaware of this fact, the default set is maintained in which activation is not (...) fed back from semantics to the lexical level so as to conserve limited resources. Qualitative differences in the pattern of data from two lexical decision experiments that employ masked priming are consistent with this hypothesis. Semantic context and stimulus quality interact when the prime is processed with awareness whereas these same two factors produce additive effects on RT when the prime is unlikely to have been processed with awareness. These experiments thus illustrate one way in which awareness affects the dynamics of visual word recognition. (shrink)

Over a century’s worth of research suggests that “perception” without awareness is a genuine phenomenon. However, relatively little research has explored the question of whether all visually presented information activates representations in long term memory without awareness. Two experiments explored the use of a figure–ground display consisting of competing views in which one view dominates the other such that subjects are unaware of the non-dominant view. Neither experiment provided evidence that the non-dominant view activated its representation in long term memory (...) when the subject failed to report being aware of the embedded word in that priming was not seen on a subsequent stem completion task. In contrast, priming was seen when subjects reported being aware of the embedded word. It is suggested that two competing figure–ground relations are not concurrently computed unconsciously.

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

Two experiments investigated the role that mental set plays in reading aloud using the task choice procedure developed by Besner and Care [Besner, D., & Care, S. . A paradigm for exploring what the mind does while deciding what it should do. Canadian Journal of Experimental Psychology, 57, 311–320]. Subjects were presented with a word, and asked to either read it aloud or decide whether it appeared in upper/lower case. Task information, in the form of a brief auditory (...) cue, appeared 750 ms before the word, or at the same time as the word. Experiment 1 yielded evidence consistent with the claim that at least some pre-lexical processing can be carried out in parallel with decoding the task cue . Experiment 2 provided evidence that such processing is restricted to pre-lexical levels . These data suggest that a task set is a necessary preliminary to lexical processing when reading aloud.

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the (...) percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. (shrink)

Recent studies show that when words are correlated with the colours they are printed in , colour identification is faster when the word is presented in its correlated colour than in an uncorrelated colour . The present series of experiments explored the possible mechanisms involved in this colour-word contingency learning effect. Experiment 1 demonstrated that the effect is already present after 18 learning trials. During subsequent unlearning, the effect extinguished equally rapidly. Two reanalyses of data from Schmidt, Crump, Cheesman, and (...) Besner ruled out an account of the effect in terms of stimulus repetitions. Experiment 2 demonstrated that participants who carry a memory load do not show a contingency effect, supporting the hypothesis that limited-capacity resources are required for learning. Experiment 3 demonstrated that memory resources are required for both storage and retrieval processes. (shrink)

This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

This is the second volume of a major new work in moral philosophy. It starts with critiques of Derek Parfit's work by four eminent moral philosophers, and his responses. The largest part of the volume is a self-contained monograph on normativity. The final part comprises seven new essays on Kant, reasons, and why the universe exists.

In the first monograph on Lyotard and education, Derek R. Ford approaches Lyotard's thought as pedagogical in itself. The result is a novel, soft, and accessible study of Lyotard organized around two inhuman educations: that of "the system" and that of "the human." The former enforces an interminable process of development, dialogue and exchange, while the latter finds its force in the mute, secret, opaque, and inarticulable. Threading together a range of Lyotard's work through four pedagogical processes-reading, writing, voicing, (...) and listening-the author insists on the distinct educational logics that can uphold or interrupt different ways of being-together in the world, touching on a range of topics from literacy and aesthetics to time and political-economy. While Inhuman Educations can serve as an introduction to Lyotard's philosophy, it also constitutes a singular, provocative, and fresh take on his thought. (shrink)

It’s intuitive to think that an intentional action requires that the agent knows that she’s doing so. In light of some apparent counterexamples, Setiya suggests that this intuitive insight is better captured in terms of credence: performing an intentional action requires the agent to have a higher credence that she’s doing so than she would have otherwise. I argue that there is no such thing as an agent’s credence for what she’s doing. After distinguishing this thesis from an idea some (...) defend under the slogan “deliberation crowds out prediction”, I explore the thesis’s broader epistemological implications for the belief-credence relation.

Mengzi states that our human nature consists of our ability to feel compassion, disdain, respect, and (dis-)approval: all human beings have them. But he also states that we lose these four emotional capacities if we don’t reflect on or attend to them. There is an apparent contradiction in saying that all humans have them, but some have lost them. This essay offers a close reading of Mengzi’s phrase “to lose it” that helps explain away this appearance of contradiction. In doing (...) so, Mengzi is interpreted to be offering an ethics of attention about how we should attend to ourselves and others selectively to have a functional social life. (shrink)

Tragedy and Citizenship provides a wide-ranging exploration of attitudes toward tragedy and their implications for politics. Derek W. M. Barker reads the history of political thought as a contest between the tragic view of politics that accepts conflict and uncertainty, and an optimistic perspective that sees conflict as self-dissolving. Drawing on Aristotle's political thought, alongside a novel reading of the Antigone that centers on Haemon, its most neglected character, Barker provides contemporary democratic theory with a theory of tragedy. He (...) sees Hegel's philosophy of reconciliation as a critical turning point that results in the elimination of citizenship. By linking Hegel's failure to address the tragic dimensions of politics to Richard Rorty, John Rawls, and Judith Butler, Barkeroffers a major reassessment of contemporary political theory and a fresh perspective on the most urgent challenges facing democratic politics. Derek W. M. Barker is a program officer at the Kettering Foundation. (shrink)

French social and philosophical thought has played a very significant role in the development of European and American social theory. This detailed, timely book provides a map of the production and reception of French social thought within a global sociological context. Critically comparing the work of five key theorists Derek Robbins examines how their ideas were produced and received before persuasively setting out the key differences between their philosophical and ideological positions. The book sensitively traces the cross-currents of social (...) theory and confidently leads the reader through the complex foundations of Western social thought. Each chapter represents a textual analysis of the production of a critical intellectual and focuses upon the work of: Althusser, Foucault, Aron, Lyotard, Bourdieu. This carefully crafted volume represents a significant contribution to the globalization of theory and will be essential reading for anyone interested in Western social theory and the foundations of sociological thought."--Publisher's website.

Traversing the fields of pedagogy, philosophy, and political theory, this book develops a marxist theory of education that will be useful for academics and activists alike. The second edition includes two additional chapters as well as a new preface and revisions throughout.

This is Thomas Reid's greatest work. It covers far more philosophical ground than the earlier, more popular Inquiry. The Intellectual Powers and its companion volume, Essays on the Active Powers of Man, constitute the fullest, most original presentation of the philosophy of Common Sense. In the process, Reid provides acutely critical discussions of an impressive array of thinkers but especially of David Hume. In Reid's eyes, Hume had driven a deep tendency in modern philosophy to its ultimate conclusions by creating (...) a phantom-world of so-called 'ideas' that sprang from objects of observation; the self was a conglomeration of perceived ideas; and the will as the source of action was nothing but the balance of passionate impulses. -/- Reid's Common Sense philosophy answers these problems by suggesting that sceptics, such as Hume, unavoidably affirm what they purport to deny, namely the existence of a stable external world, of other minds, of the continuity of their own minds, and of their own and other people's ability to ascribe and accept responsibility for actions. We can understand all of this by proper empirical observation and philosophical analysis of the activity of the mind. Reid's major positive contribution to philosophy is a detailed account of the various innate powers of the mind. While particularly influential in the first half of the nineteenth century, Reid's work has retained a significant role in philosophy, not least in recent years. At the same time, his role in the Scottish Enlightenment is becoming much better understood. -/- This is the only properly established text. It is accompanied by manuscript lectures on the nature and immortality of the soul, as well as helpful editorial annotation and introduction, making it useful to a wide variety of readers. -/- Key Features: -/- Accurate, reliable and critically established text; The Introduction explains the work's genesis and its place in Reid's system; Annotations provide an understanding of Reid's context; An Appendix contains manuscript material covering an important topic not represented in the hitherto published work.

From David Hume's famous puzzle about 'the missing shade of blue' to current research into the science of colour, the topic of colour is an incredibly fertile region of study and debate, cutting across philosophy of mind, epistemology, metaphysics and aesthetics as well as psychology. Debates about the nature of our experience of colour and the nature of colour itself are central to contemporary discussion and argument in philosophy of mind and psychology, and philosophy of perception. This outstanding Handbook contains (...) twenty-nine specially commissioned contributions by leading philosophers and examines the most important aspects of philosophy of colour. It is organised into six parts: The Importance of Colour to Philosophy The Science and Spaces of Colour Colour Phenomena Colour Ontology Colour Experience and Epistemology Language, Categories and Thought. The Routledge Handbook of Philosophy of Colour is essential reading for students and researchers in philosophy of mind and psychology, epistemology, metaphysics and aesthetics, as well as for those interested in conceptual issues in the psychology of colour.
