We used a qualitative dissociation procedure to assess semantic priming from spatially attended and unattended masked words. Participants categorized target words that were preceded by parafoveal prime words belonging to either the same or the opposite category as the target. Using this paradigm, only non-strategic use of the prime would result in facilitation of the target responses in related trials. Primes were immediately masked or masked with a delay, while spatial attention was allocated to the primes’ location or away from (...) the primes’ location. Immediate masked, strongly related primes facilitated target responses irrespective of the spatial attention. Delayed masked, related primes led to reversed or facilitatory priming depending on whether they were cued or uncued. These findings demonstrate that perceiving a stimulus with or without awareness depends on both stimulus quality and attention orienting and that non-strategic priming can be observed from clear visible but spatially unattended words.

Perceptual fluency is the subjective experience of ease with which an incoming stimulus is processed. Although perceptual fluency is assessed by speed of processing, it remains unclear how objective speed is related to subjective experiences of fluency. We present evidence that speed at different stages of the perceptual process contributes to perceptual fluency. In an experiment, figure-ground contrast influenced detection of briefly presented words, but not their identification at longer exposure durations. Conversely, font in which the word was written influenced (...) identification, but not detection. Both contrast and font influenced subjective fluency. These findings suggest that speed of processing at different stages condensed into a unified subjective experience of perceptual fluency. (shrink)

We first describe how the concept of “fringe consciousness” can characterise gradations of consciousness between the extremes of implicit and explicit learning. We then show that the NEO-PI-R personality measure of openness to feelings, chosen to reflect the ability to introspect on fringe feelings, influences both learning and awareness in the serial reaction time task under conditions that have previously been associated with implicit learning . This provides empirical evidence for the proposed phenomenology and functional role (...) of fringe consciousness in so-called implicit learning paradigms . Introducing an individual difference variable also helped to identify possible limitations of the exclusion task as a measure of conscious sequence knowledge. Further exploration of individual differences in fringe awareness may help to avoid polarity in the implicit learning debate, and to resolve apparent inconsistencies between previous SRT studies.

Mangan draws his inspiration from James's account of fringe consciousness, but differs from James in focusing on something non-sensory, necessarily fuzzy, though not necessarily fleeting. A long tradition in philosophy has deemed non-sensory elements of consciousness to be indispensable to thought. But those, chiefly conceptual, forms of non-sensory fringe are not Mangan's focus. What then is Mangan talking about? This commentary envisages a number of possible answers, and tentatively concludes that fringe consciousness is essentially (...) emotional. Emotional consciousness involves proprioception, however, hence is non-sensory only in the weak sense of excluding the five senses. (shrink)

Ayahuasca, a hallucinogen with profound consciousness- altering properties, has been increasingly utilized in recent studies (e.g., Strassman, 2001; Shanon, 2002a,b). However, other than Shanon's recent work, there has been little attempt to examine the effects of ayahuasca on perceptual, affective and cognitive experience, its relation to fringe consciousness or to pertinent personality variables. Twenty-one volunteers attending a seminar on ayahuasca were administered personality measures and a semi-structured interview about phenomenal qualities of their experience. Ayahuasca ingestion was associated (...) with profound alterations of temporal- spatial experiences including expansive space and slowed time. Ayahuasca use was also associated with positive emotional states, higher levels of fantasy proneness and psychological absorption and a greater openness to mystical experiences. Conversely, quickened time was associated with negative emotionality. The results are discussed within a multi-faceted model of fringe consciousness with a particular emphasis on Hunt's (1995) models of cross-modal translation as the basis for higher-order symbolic cognition and support James' (1890/1950) contention that fringe consciousness is essential to human cognition.

A technique for the bilateral activation of neural nets that leads to a functional asymmetry of two simulated ''cerebral hemispheres'' is described. The simulation is designed to perform object recognition, while exhibiting characteristics typical of human consciousness-specifically, the unitary nature of conscious attention, together with a dual awareness corresponding to the ''nucleus'' and ''fringe'' described by William James (1890). Sensory neural nets self-organize on the basis of five sensory features. The system is then taught arbitrary symbolic labels for (...) a small number of similar stimuli. Finally, the trained network is exposed to nonverbal stimuli for object recognition, leading to Gaussian activation of the ''sensory'' maps-with a peak at the location most closely related to the features of the external stimulus. ''Verbal'' maps are activated most strongly at the labeled location that lies closest to the peak on homologous sensory maps. On the verbal maps activation is characterized by both excitatory and inhibitory Gaussians (a Mexican hat), the parameters of which are determined by the relative locations of the verbal labels. Mutual homotopic inhibition across the ''corpus callosum'' then produces functional cerebral asymmetries, i.e., complementary activation of homologous ''association'' and ''frontal'' maps within a common focus of attention-a nucleus in the left hemisphere and a fringe in the right hemisphere. An object is recognized as corresponding to a known label when the total activation of both hemispheres (nucleus plus fringe) is strongest for that label. The functional dualities of the cerebral hemispheres are discussed in light of the nucleus/fringe asymmetry. (shrink)

This paper evaluates Mangan’s (1993) analysis of the way feelings at the fringes of consciousness provide global evaluations of what is happening at the focus of attention in ways that allow the human mind to direct its activities in an effective, adaptive way—elaborating on a distinction between fringe consciousness and focal-attentive consciousness originally developed by William James. The paper argues that, while Mangan’s analysis is a plausible account of mental operations, viewed from a first-person perspective, it (...) is inconsistent with a detailed account of human information processing viewed from a third-person perspective, which largely operates in an unconscious fashion. It also ignores classical problems relating to consciousness-brain causal interaction in philosophy of mind, and the subtlety different ways in which information processing can be said to be “conscious”. The paper then offers an alternative interpretation of the evidence (following Velmans, 1991) in which first- and third-person accounts of mental processing are complementary and mutually irreducible.

High figure-ground contrast usually results in more positive evaluations of visual stimuli. This may either reflect that high figure-ground contrast per se is a desirable attribute or that this attribute facilitates fluent processing. In the latter case, the influence of high figure-ground contrast should be most pronounced under short exposure times, that is, under conditions where the facilitative influence on perceptual fluency is most pronounced. Supporting this hypothesis, ratings of the prettiness of visual stimuli increased with figure-ground contrast under short (...) exposure times (.3, 1, and 3 seconds, respectively). This positive influence of figure-ground contrast was eliminated under an exposure time of 10 seconds. We conclude that stimuli with high figure-ground contrast are more appealing because they are easier to process, not because high figure-ground contrast per se is a desirable attribute. We discuss this finding in the context of William James? notion that the fringe of consciousness includes vague contextual feelings at the periphery of the focus of attention and suggest that perceptual fluency is one of these feelings.

One of the aspects of consciousness deserving of study is what might be called its subjective unity - the way in which, though conscious experience moves from object to object, and can be said to have distinct ‘states', it nevertheless in some sense apparently forms a singular flux divided only by periods of unconsciousness. The work of William James provides a valuable, and rather unique, source of analysis of this feature of consciousness; however, in my opinion, this component (...) of James’ theory of the mind has so far gone under-emphasized in the scholarly literature. This paper undertakes some philosophical geography, trying to draw out and elucidate some of the relevant ideas from James’ corpus, and also subjects those ideas to some analysis to try and assist in judgements of their current importance.

All our conscious experiences, linguistic and nonlinguistic, are bound up with and dependent on a background that is vague, unexpressed, and sometimes unconscious. The combination of William JamesÕs concept of "fringes" coupled with Aaron GurwitschÕs analysis of the field of consciousness provides a general structure in which to embed phenomenal descriptions, enabling fringe phenomena to be understood, in part, relative to other experiences. I will argue, drawing on examples from Drew LederÕs book, The Absent Body, that specific and (...) detailed phenomena can and should be interrelated through JamesÕs and GurwitschÕs analyses. I am proposing first that phenomenological descriptions in general could benefit from explicit consideration of the context of the phenomena within the totality of the field of consciousness, and second, that establishing that context requires a general structural model of that field, similar to that provided by Gurwitsch.

Previous research found that mixed handers were more likely than strong handers to update their beliefs . It was assumed that this was due to greater degrees of communication between the two cerebral hemispheres in mixed handers. Niebauer and Garvey made connections between this model of updating beliefs and metacognitive processing. The current work proposes that variations in interhemispheric interaction contribute to differences in consciousness, specifically when consciousness is used in rumination versus the metacognitive task of self-reflection. Using (...) the Rumination–Reflection Questionnaire , predictions were supported such that strong handedness was associated with self-rumination; whereas, mixed handedness was associated with increased self-reflection p values < .01, . James’s concept of the “fringe of consciousness” is used to make connections between metacognition, updating beliefs, and self-reflection. Several studies are reviewed suggesting that mixed handers experience fringe consciousness to a greater degree than strong handers. (shrink)

In intuitions concerning semantic coherence participants are able to discriminate above chance whether a word triad has a common remote associate or not . These intuitions are driven by increased fluency in processing coherent triads compared to incoherent triads, which in turn triggers a brief and short positive affect. The present work investigates which of these internal cues, fluency or positive affect, is the actual cue underlying coherence intuitions. In Experiment 1, participants liked coherent word triads more than incoherent triads, (...) but did not rate them as being more fluent in processing. In Experiment 2, participants could intuitively detect coherence when they misattributed fluency to an external source, but lost this intuitive ability when they misattributed affect. It is concluded that the coherence-induced fluency by itself is not consciously experienced and not used in the coherence intuitions, but the fluency-triggered affective consequences. (shrink)

Using the form of cinematic montage, this essay explores the nature of historical consciousness in a mass-mediated culture where historical discourse takes the form of both showing and saying, moving images and written words. The title draws upon and argues with Roland Barthes's critique of the duplicity of the "insistent fringes" that supposedly reduce and naturalize "Roman-ness" to fringed hair in popular historical film. Barthes presumes a "certainty" in such a cinematic image, and hence deems it mythological-that is, "it (...) goes without saying." Countering Barthes with Walter Benjamin, one might argue that the "insistent fringe" is insistently historical and constitutes, in its insistence, a "dialectical image": a site and sight full of contradictions and open to excavation. That is, it concretizes historiographic saying by showing. Neither historiographic saying nor showing are privileged in medias res-in a culture saturated in images and textuality, in competing modes of expression each of which has its limits. Historical consciousness is sparked and constituted from both showing and saying. Indeed, the "insistent fringe" is precisely not clear-cut-and, if it insists on anything, it is its serrated nature, its articulation as a limit that differs from, but is constituted by, the elements of the two distinct domains which it both separates and connects. Similarly, there is a dynamic, functional, and hardly clear-cut relation that exists between the mythological histories wrought by Hollywood cinema and the academic histories written by scholars. They co-exist, compete, and cooperate in a contingent, heteroglossic, and always shifting ratio-thus constituting the "rationality" of contemporary historical consciousness. (shrink)

Non-sensory experiences represent almost all context information in consciousness. They condition most aspects of conscious cognition including voluntary retrieval, perception, monitoring, problem solving, emotion, evaluation, meaning recognition. Many peculiar aspects of non-sensory qualia (e.g., they resist being 'grasped' by an act of attention) are explained as adaptations shaped by the cognitive functions they serve. The most important nonsensory experience is coherence or "rightness." Rightness represents degrees of context fit among contents in consciousness, and between conscious and non-conscious processes. (...) Rightness (not familiarity) is the feeling-of-knowing in implicit cognition. The experience of rightness suggests that neural mechanisms "compute" signals indicating the global dynamics of network integration. (shrink)

The Jamesian notion of fringe consciousness as elaborated by Mangan provides a theoretical motivation for drawing together a diverse class of experiences which are called "feelings" in everyday language. Thus, feelings of knowing and emotional feelings are seen not to differ in kind from each other. Further, both kinds of feelings are seen to reflect the consonance or dissonance of current conscious experience with unconscious contexts and may be used as "handles" to draw unconscious material into consciousness.

William James’ greatest achievement is, arguably, his analysis of the fringe -- or, as he sometimes called it, transitive experience. In trying to understand this vague, elusive, often peripheral aspect of consciousness, James broke new ground. But in so doing he also began to lay down the first stratum of a radically new methodology, one that intersects first- and third-person findings in such a way that each is able to interrogate the other, and so further our understanding of (...) both.

Evidence and theory ranging from traditional philosophy to contemporary cognitive research support the hypothesis that consciousness has a two-part structure: a focused region of articulated experience surrounded by a field of relatively unarticulated, vague experience.William James developed an especially useful phenomenological analysis of this "fringe" of consciousness, but its relation to, and potential value for, the study of cognition has not been explored. I propose strengthening James′ work on the fringe with a functional analysis: fringe (...) experiences work to radically condense context information in consciousness; are vague because a more explicit representation of context information would overwhelm consciousness′ limited articulation capacity; help mediate retrieval functions in consciousness; and contain a subset of monitoring and control experiences that cannot be elaborated in focal attention and are "ineffable." In general, the phenomenology of the fringe is a consequence of its cognitive functions, constrained by consciousness′ limited articulation capacity. Crucial to monitoring and control is the feeling of "rightness." Rightness functions as a summary index of cognitive integration, representing, in the fringe, the degree of positive fit between a given conscious content and its parallel, unconsciously encoded context. Rightness appears analogous to the connectionist metric of global network integration, known variously as goodness-of-fit, harmony, or minimum energy. (shrink)

In a recent article, [Sergent, C. & Dehaene, S. . Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink, Psychological Science, 15, 720–729] claim to give experimental support to the thesis that there is a clear transition between conscious and unconscious perception. This idea is opposed to theoretical arguments that we should think of conscious perception as a continuum of clarity, with e.g., fringe conscious states [Mangan, B. . Sensation’s ghost—the non-sensory “fringe” (...) of consciousness, Psyche, 7, 18]. In the experimental study described in this article, we find support for this opposite notion that we should have a parsimonious account of conscious perception. Our reported finding relates to the hypothesis that there is more than one perceptual threshold [Merikle, P.M., Smilek, D. & Eastwood, J.D. . Perception without awareness: perspectives from cognitive psychology, Cognition, 79, 115–134], but goes further to argue that there are different “levels” of conscious perception. (shrink)

The purpose of this article is to present a more thoroughgoing account of what James means by the fringes of perceptual objects. The first section presents James's account of fringes of objects of consciousness within the context of his celebrated analogy of the stream of the fringe phenomenon for perception. It concludes by proposing a preliminary "working" definition of the concept "fringe": fringes are active bridges of associations (logical, psychological, etc.) from what is perceptually immediate but ambiguous (...) to what the perceptual process "analyzes" and make definite.

Both visual experience and conscious thought represent external objects, but in visual experience these objects seem present before the mind and available for direct access in a way that they don’t in conscious thought. In this paper, I introduce a couple of challenges that this “Scene-Immediacy” of visual experience raises for traditional versions of Representationalism. I then identify a resource to which Representationalists can appeal in addressing these challenges: the low-detail fringe of visual experience. I argue that low-detail contents (...) within visual experience provide the mind with a rich access to additional high-detail information, an access that is not found in conscious thought. This access, in turn, speaks to the challenges raised by the Scene-Immediacy of visual experience. Robert Schroer is an Assistant Professor at the University of Minnesota at Duluth. (shrink)

After suggesting an operational definition for fringe experiences—as opposed to clearly conscious and clearly unconscious phenomena—we examine three empirical cases: The tip-of-the-tongue experience, the fringe experience of "wrongness," and the case of conscious focus on abstract, hard-to-image conscious contents. In each case, Mangan′s four major claims are explored in some detail. Most tasks seem to involve a combination of conscious experiences, complex unconscious representations, and multiple fringe experiences. The chief disagreement from this analysis involves vague experiences that (...) are generally believed to be focal: The case of currently topical abstract concepts, which are not reported as conscious images or percepts. In the interest of caution, it may be better to speak of "conscious access" to focal abstract concepts, rather than "conscious experience" of such concepts. There may be other vague but focally conscious phenomena, such as an intention to act, the signal for executing a prepared action, and so on. Mangan′s points are generally supported, with some qualifications. (shrink)

From his preliminary analysis in 1965, Hubert Dreyfus projected a future much different than those with which his contemporaries were practically concerned, tempering their optimism in realizing something like human intelligence through conventional methods. At that time, he advised that there was nothing “directly” to be done toward machines with human-like intelligence, and that practical research should aim at a symbiosis between human beings and computers with computers doing what they do best, processing discrete symbols in formally structured problem domains. (...) Fast-forward five decades, and his emphasis on the difference between two essential modes of processing, the unconscious yet purposeful mode fundamental to situated human cognition, and the “minded” sense of conscious processing characterizing symbolic reasoning that seems to lend itself to explicit programming, continues into the famous Dreyfus–McDowell debate. The present memorial reviews Dreyfus’ early projections, asking if the fears that punctuate current popular commentary on AI are warranted, and in light of these if he would deliver similar practical advice to researchers today.

In his novel Remembrance of Things Past, Marcel Proust argues that conventional descriptions of the phenomenology of consciousness are incomplete because they focus too much on the highly-salient sensory information that dominates each moment of awareness and ignore the network of associations that lies in the background. In this paper, I explicate Proust’s theory of conscious experience and show how it leads him directly to a theory of aesthetic perception. Proust’s division of awareness into two components roughly corresponds to (...) William James’ division of the stream of thought into a “nucleus” and “fringe.” Proust argues that the function of art is to evoke the underlying associative network indirectly in the mind of the observer by using carefully chosen sensory surfaces to control the stream of thought. I propose a possible neural basis for this Proustian/Jamesian phenomenology, and argue that the general principles of Proustian aesthetics can be applied to all forms of art. I conclude that a scientific theory of art should follow in a straightforward manner from a scientific theory of consciousness. (shrink)

In the last decade, careful studies of the living brain have opened the way for human consciousness to return to the heights it held before the behavioristic coup of 1913. This is illustrated by seven cases: the discovery of widespread brain activation during conscious perception; high levels of regional brain metabolism in the resting state of consciousness, dropping drastically in unconscious states; the brain correlates of inner speech; visual imagery; fringe consciousness; executive functions of the self; (...) and volition. Other papers in this issue expand on many of these points. . In the past, evidence based on subjective reports was often neglected . It is still true that brain evidence has greater credibility than subjective reports, no matter how reliable. What is new is increasing convergence between subjective experiences and brain observations. For that reason it is no longer rare to see the word 'consciousness' and 'subjectivity' in major science journals. No one so far has discovered a gulf dividing mind and brain. On the contrary, the new evidence supports the central role of consciousness as it was regarded over more than two millenia of written thought. In a sense this was predictable. Nature is full of unexpected convergences -- between fruit fly genes and the human body, between the arc of a tennis ball and the orbit of Mars, and between consciousness and the brain. These convergences show once again the remarkable unity of the observable universe. (shrink)

So the central question here is phenomenological: What is the nature of the aesthetic zap? For it is this experience, or its promise, which gives art such a deep hold on human life. But the issue of representation, while secondary, is still pregnant with cognitive implications: Why is representation, of all the devices available to an artist, more likely to shift the odds in favour of eliciting and/or intensifying aesthetic experience? Assuming a Darwinian view of our species, it is likely (...) that the answer to both questions will come from understanding how our capacity to enjoy art grows out of normal cognition. (shrink)

Most recent philosophical theories of consciousness account for it in terms of representation, the bulk of the debate revolving around whether (suitably) representing something is sufficient for consciousness (as per first-order representationalism) or some further (meta-)representation is needed (as per higher-order representationalism and self-representationalism). In this paper, I explore an alternative theory of consciousness, one that aims to explain consciousness not in terms of representation but in terms of the epistemically and metaphysically direct relation of acquaintance. (...) I call this the Inner Acquaintance Theory of consciousness (IAT). Roughly, on IAT, what makes a mental state conscious is its subject being acquainted with it. Though not wholly unprecedented, IAT is still at the fringe of consciousness debates and remains largely underexplored. The main goal of this paper is to take some steps toward developing the details of IAT, illustrate its potential explanatory power, and put it forward as a plausible alternative to representational theories, with the hope that this will contribute to shifting IAT closer to the center of the debate. Here is how I proceed. In §2 I introduce a notion—inner awareness—that is crucial both to contextualize and to understand IAT. In §3 I provide some preliminary motivation for exploring IAT. In §4 I explain the notion of acquaintance and illustrate some of the features that are typically attributed to it in the literature. The details of IAT are then shaped through four main decision points. I address them in §§5-8, where I suggest a particular choice at each decision point, thereby progressively building up a view that I consider particularly promising. (shrink)

William James and Aron Gurwitsch form a one-two punch on disclosing the nature of the field of consciousness. James claims that it is comprised of two parts, a focus (the center of our attention) and a margin (everything else). Gurwitsch expands on James' account by noting that the margin itself is comprised of relevant data and irrelevant data. The former he calls "thematic field" and the latter he calls "margin." So Gurwitsch argues for a three-dimensional or three-part field of (...) consciousness, theme (or focus), thematic-field, and margin, and shows that James' two part field-theory is inadequate. I discuss the similarities and differences between the two theories, including how James notion of "fringe" is meant to convey some relevance for non-focal data. (shrink)

Consciousness is a hot topic. Relegated to the fringes of science for most of the twentieth century, the question of consciousness only crept back to legitimacy with the collapse of behaviourism in the 1960s and 1970s, and only recently became an acceptable term for psychologists to use. Now many neuroscientists talk enthusiastically about the nature of consciousness, there are societies and regular conferences, and some say that consciousness is the greatest challenge for twenty-first century science. Although (...) confusion abounds, there is at least some agreement that at the heart of the problem lies the question of subjectivity - or what it’s like for _me_. As philosopher Thomas Nagel (1974) put it when he asked his famous question "What is it like to be a bat?" - if there is something it is like _for the bat_ then we can say that the bat is conscious. This is what we mean by consciousness - consciousness is private and subjective and this is why it is so difficult to understand. (shrink)
