ABSTRACTRumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related (...) to affect change. Given that greater verbal thought was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal t... (shrink)

The use of visual mental imagery has been proposed to be a risk factor for the development of bipolar disorder, due to its potential to amplify affective states. This study examined the relation between visual imagery , intrusive verbal thought, and hypomania, as assessed by self-report questionnaires, in a sample of young adults . Regression analyses found that levels of intrusive visual imagery predicted levels of hypomania, but that neither trait use of visual imagery nor intrusive verbal (...) thought did. These results were consistent with the proposal that being a ‘visualiser’, as opposed to a ‘verbaliser’, is a risk factor for bipolar disorder, with the caveat that it is specifically intrusive experiences of imagery, rather than the tendency to utilize imagery per se, that acts as a risk factor.

Passivity experiences in schizophrenia are thought to be due to a failure in a neurocognitive action self-monitoring system . Drawing on the assumption that inner speech is a form of action, a recent model of auditory verbal hallucinations has proposed that AVHs can be explained by a failure in the NASS. In this article, we offer an alternative application of the NASS to AVHs, with separate mechanisms creating the emotion of self-as-agent and other-as-agent. We defend the assumption that (...) inner speech can be considered as a form of action, and show how a number of previous criticisms of applying the NASS to AVHs can be refuted. This is achieved in part through taking a Vygotskian developmental perspective on inner speech. It is suggested that more research into the nature and development of inner speech is needed to further our understanding of AVHs. (shrink)

Can we think without words? At first, the question is surprising, and the answer is most often, “No.”This response is quite understandable. Words and thought are so closely connected in our mental activity that they appear almost indissociable, since if we follow an introspective process, it is not possible for us to analyze our reasoning and our feelings without having recourse to words. Moreover, man's verbal expression is not only a means of communication; it is also an instrument (...) of progress for the mind, without which the mind would not be able to attain the very high levels of abstract and conceptual thought that are proper to it. No one would dream of minimizing the important influence of words on thought. It is more correct to magnify it as Paul Valéry did: “The honor of man, blessed speech.”. (shrink)

Combining two thoughts into a compound mental representation is a central feature of our verbal and non-verbal logical abilities. We here approach this issue by focusing on the contingency that while natural languages have typically lexicalised only two of the possible 16 binary connectives from formal logic to express compound thoughts—namely, the coordinatorsandandor—some of the remainder appear to be entertainable in a non-verbal, conceptual representational system—alanguage of thought—and this suggests a theoretical split between the “lexicalisation” of (...) the connectives and the “learnability” of invented words corresponding to unlexicalised connectives. In avisual worldexperiment aimed at tracking comprehension-related as well as reasoning-related aspects of the capacity to represent compound thoughts, we found that participants are capable of learning and interpreting a made-up word standing for logic's NAND operator, a result that indicates that unlexicalised logical connectives are not only conceptually available, but can also be mapped onto new function words, as in the case of coordinators, or connectives, a class of words that do not usually admit new coinages.

Recent proposals for a return to introspective methods make it necessary to review the central problems that led psychologists to abandon those methods as sources of scientific data in the early twentieth century. These problems and other related challenges to verbal reports collected during the cognitive revolution during the 1960s and 1970s were discussed in Ericsson and Simon's proposal for a theoretically motivated procedure to elicit valid and non- reactive concurrent verbalization of thoughts while subjects were performing tasks. The (...) same proposal explains why other verbal reports, such as introspections, detailed descriptions or explanations, require additional cognitive activity that often leads to reactivity and invalid reports. Finally, a new proposal is sketched for how the generation of introspective reports might be incorporated within a framework for non-reactive and valid verbalization of thoughts. (shrink)

A neuropsychological perspective on auditory verbal hallucinations links key phenomenological features of the experience, such as voice location and identity, to functionally separable pathways in normal human audition. Although this auditory processing stream framework has proven valuable for integrating research on phenomenology with cognitive and neural accounts of hallucinatory experiences, it has not yet been applied to other symptoms presumed to be closely related to AVH – such as thought insertion. In this paper, I propose that an APS (...) framework offers a useful way of thinking about the experience of TI as well as AVH, providing a common conceptual framework for both. I argue that previous self-monitoring theories struggle to account for both the differences and similarities in the characteristic features of AVH and TI, which can be readily accommodated within an APS framework. Furthermore, the APS framework can be integrated with predictive processing accounts of psychotic symptoms; makes predictions about potential sites of prediction error signals; and may offer a template for understanding a range of other symptoms beyond AVH and TI.

Sellars’ verbal behaviorism demands that linguistic episodes be conceptual in an underivative sense and his theoretical mentalism that thoughts as postulated theoretical entities be modelled on linguistic behaviors. Marras has contended that Sellars’ own methodology requires that semantic categories be theoretical. Thus linguistic behaviors can be conceptual in only a derivative sense. Further he claims that overt linguistic behaviors cannot serve as a model for all thought because thought is primarily symbolic. I support verbal behaviorism by (...) showing that semantic categories are in the first instance teleological explanatory categories and consequently can be observational. And I show how theoretical mentalism can be maintained even though thought is primarily symbolic. (shrink)

The conjunction fallacy occurs whenever probability compounds are thought of as more likely than its component probabilities alone. In the experiment we present, subjects chose between simple and compound lotteries after some practice. Depending on the condition, they were given more or less information about the nature of probability compounds. The conjunction fallacy was surprisingly robust. There was, however, a puzzling dissociation between verbal and behavioral learning: verbal responses were sensitive, but actual choices entirely insensitive, to the (...) amount of verbal instructions being provided. This might reflect a dichotomy between implicit and explicit learning. Caution must be exercised in generalizing results from what people say to what people do. (shrink)

Patients with psychotic disorders experience a range of reality distortions. These often include auditory-verbal hallucinations, and thought insertion to a lesser degree; however, their mechanisms and relationships between each other remain largely elusive. Here we attempt to establish a integrative model drawing from the phenomenology of both AVHs and TI and argue that they in fact can be seen as ‘spectra’ of experiences with varying degrees of agency and ownership, with ‘silent and internal own thoughts’ on one extreme (...) and ‘fully external and clearly audible voices’ in the absence of a speaker on the other. We believe a spectral model will add emphasis to the continuity of experience and help to better understand how one type of psychotic symptom may interact with another, and put forward the argument that the experience of TI itself is not sufficient to classify as a delusion. In addition we aim to discuss some of the conceptual issues surrounding AVHs and TI with first-person accounts and current philosophical and neuropsychological theories in mind. We propose that the mechanisms behind AVHs and TI are more complex than source-monitoring deficits; indeed, to understand such phenomena one must appreciate that their very ‘existence’ and ‘reality’ as experienced by the individual have much deeper implications and meaning, both philosophically and clinically.

Auditory verbal hallucinations form an essential criterial feature in the schizophrenia definition in the Diagnostic and Statistical Manual of Mental Disorders -IV and International Classification of Diseases -10. In both classificatory systems, the presence of a hallucinatory voice that continuously comments the patient’s behavior or thoughts, or the presence of several voices that discuss the patient with each other, is a sufficient criterion to diagnose schizophrenia. The DSM-IV defines a hallucination as “a sensory perception that has the..

About 75% of subjects diagnosed with schizophrenia experience auditory-verbal hallucination and report "hearing voices" that are not actually present. One notable feature of AVH is that it seems involuntary and not directly in the subject's control. With regard to content, these represented voices make utterances, typically commands and evaluations, and either are directed to the patient or speak about her in the third person. Voices may echo the subject's thoughts or comment on the subject's behavior and, in some cases, (...) the voices seem to carry on conversations or even argue. Subjects often experience the voices as having pitch, timbre, and intensity, and as having a... (shrink)

Speakers can express a critical, dissociative attitude by being ironic. According to the Echoic account of verbal irony, this attitude targets a proposition that echoes a thought attributed to someone other than the speaker herself at the present time. This study investigated the role of echo in irony processing across the lifespan. Through a self-paced reading task, we assessed whether the degree of explicitness of the proposition echoed by the ironical statement and the age of the participant influenced (...) irony processing. Our results show that, independently of age, ironic statements were costlier to process than literal statements, with aging further increasing difficulty. Crucially, our manipulation of the echo affected reading times: it was more complex to process irony when this echoed an implicature or an implicit expectation, particularly for older adults. This work corroborates the role of the echo in verbal irony providing insights into age-related changes in irony processing. (shrink)

How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? Most investigators have assumed that alterations in sensory features of imagery explain this. This approach, however, has not yielded a definitive picture of the nature of verbal hallucinations. An alternative perspective suggests itself if one allows the possibility that the nonself quality of hallucinations is inferred on the basis of the experience of unintendedness that accompanies imagery production. Information-processing models of “intentional” cognitive processes call (...) for abstract planning representations that are linked to goals and beliefs. Unintended actions - and imagery - can reflect planning disruptions whereby cognitive products do not cohere with concurrent goals. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning. Insofar as verbal imagery can be viewed as inwardly directed speech, a consequence of such planning disturbances could be the production of unintended imagery. This link between the outward disorganization of schizophrenic speech and unintended verbal imagery is statistically supported by comparing the speech behavior of hallucinating and nonhallucinating schizophrenics. Studies of “borderline” hallucinations during normal, “goal-less” relaxation and drowsiness suggest that experiential unintendedness leads to a nonpathological variant of hallucinatory otherness that is correctable upon emerging from such passive cognitive states. This contrasts with the schizophrenic case, where nonconcordance with cognitive goals reinforces the unintendedness of verbal images and sustains the conviction of an external source. This model compares favorably with earlier models of verbal hallucinations and provides further evidence for a language production disorder in many schizophrenics.Short Abstract: How is it that many schizophrenics identify certain instances of verbal imagery as hallucinatory? This paper proposes that the critical feature identifying hallucinations is the experience of unintendedness. This experience is nonpathological during passive conscious states but pathological if occurring during goal-directed cognitive processing. A model of schizophrenic speech disorganization is presented that postulates a disturbance of discourse planning that specifies communicative intentions. These alterations could generate unintended verbal imagery as well. Statistical data are offered to support the model, and relevant empirical studies are reviewed. (shrink)

Many have thought that exercises of skill are intentional. The argument of the paper is that this thesis fails to account for important types of mistakes and errors. In what psychologists and linguists call “verbal slips with semantic bias”, a speaker mistakenly switches, reverses, or blends certain conceptual contents. Nevertheless, the speaker has successfully exercised an intellectual skill, insofar as her slip uses concepts in conformity to semantic and logical rules. To flesh out how one might successfully exercise (...) skills without doing so intentionally, the paper appeals to the idea of habit. Verbal slips thus show how human skillfulness has a considerably wider scope than is often supposed. (shrink)

The subject of this report is a border region between two languages: that of the Zen kōan and that of formal logic. Firstly, I present part of a classic work of Zen Buddhism, the Hekiganroku (Biyen-lu, 碧巌録) with some additional commentary. Secondly, I put forward a possible means of translating Zen kōans into the language of formal logic. This exposition is tied to a three-fold problematic: Is it possible to say that the different logics (of the language of Zen and (...) the language of formal logic) agree in their logical essence? If so, in which aspects can we find these points of agreement? Or do they represent only different parallel logics without any points of crossing? What is the definitive difference between their respective ways of thinking? The answers to these questions may providecontemporary buddhist philosophy with a further perspective: how Zen thought can stimulate and contribute to formal logic. The transcription of Zen kōan into formal logical symbols is able to clarify what is the most important subject in the language of Zen. At the same time it will show the limitations of the language of formal logic and the language of Zen kōan. In my report I try to delineate the limits of verbal expression in formal logic and explore what is the truth expressed in nonverbal applications of Zen logic. A new way of thinking can emerge from the field between the logic of verbal and of non-verbal expression. (shrink)

'Thought insertion' in schizophrenia involves somehow experiencing one's own thoughts as someone else's. Some philosophers try to make sense of this by distinguishing between ownership and agency: one still experiences oneself as the owner of an inserted thought but attributes it to another agency. In this paper, we propose that thought insertion involves experiencing thought contents as alien, rather than episodes of thinking. To make our case, we compare thought insertion to certain experiences of ' (...) class='Hi'>verbal hallucination' and show that they amount to different descriptions of the same phenomenon: a quasi-perceptual experience of thought content. We add that the agency/ownership distinction is unhelpful here. What requires explanation is not why a person experiences a type of intentional state without the usual sense of agency, but why she experiences herself as the agent of one type of intentional state rather than another. We conclude by sketching an account of how this might happen. (shrink)

The standard interpretation of cognitive reflection tests assumes that correct responses are reflective and lured responses are unreflective. However, prior process-tracing of mathematical reflection tests has cast doubt on this interpretation. In two studies (N = 201), we deployed a validated think-aloud protocol in-person and online to test how this assumption is satisfied by the new, validated, less familiar, and less mathematical verbal Cognitive Reflection Test (vCRT). Importantly, thinking aloud did not disrupt test performance compared to a control group. (...) Moreover, verbalized thoughts in both studies revealed that most (but not all) correct responses involved reflection and that most (but not all) lured responses lacked reflection. These data suggest that the vCRT usually satisfies the standard interpretation of the reflection tests (albeit not without exceptions) and that the vCRT can be a good measure of the construct theorized by the two-factor explication of ‘reflection’ (as deliberate and conscious).

ABSTRACT This article deals with the communicational aspects of Aristotle’s theory of signification as laid out in the initial chapters of the De Interpretatione (Int.).1 We begin by outlining the reception and main interpretations of the chapters under discussion, rather siding with the linguistic strand. We then argue that the first four chapters present an account of verbal communication, in which words signify things via thoughts. We show how Aristotle determines voice as a conventional and hence accidental medium of (...) signification: words as ‘spoken sounds’ are tokens of thoughts, which in turn are signs or natural likenesses of things. We argue that, in this way, linguistic expressions may both signify thoughts and refer to things. This double account of signification also explains the variety of ontological, logical and psychological interpretations of the initial chapters of Int. (shrink)

The article highlights George Herbert Mead’s and Wilfrid Sellars’ reliance on a behaviourally-grounded conception of meaning as strictly related to the possibility of distinguishing mental from non-mental phenomena as both related to the semantic dimension. Mead’s position is in fact akin to Wilfrid Sellars’ argument that the concepts of ‘inner events’ are essentially inter-subjective. Thoughts are displayed as consisting of related linguistic acts linked inferentially through intra-linguistic moves that respond to a particular ‘language practice’ governed by norms. Introspection is an (...) ‘inner conversation’, namely an ‘inner’ speaking analogous to linguistic activity that does not involve actual equivalents of the words in the mind. (shrink)

Why should musical compositions and artistic images be included among the types of expression covered by free speech principles? One way to answer this question is to show how expression in nonverbal media can be functionally similar to other types of verbal expression. But this leaves us with an intuitively unsatisfying explanation of why free speech principles cover nonverbal creative expression that does not functionally emulate literal speech. In this article, as an alternative justification, we develop and defend the (...) idea that musical and pictorial expression‚ much like literal speech, can be media through which people think aloud, as opposed to mere tools for the transmission of thought. We use this proposal to provide a more robust justification for including nonverbal creative expression in the scope of free speech coverage, and we outline some of the practical policy implications that come with adopting this justificatory strategy.

This paper addresses four issues: 1. What is nonsense? 2. Is nonsense possible? 3. Is nonsense actual? 4. Why do the answers to (1)–(3) matter, if at all? These are my answers: 1. A sentence (or an utterance of one) is nonsense if it fails to have or express content (more on ‘express’, ‘have’, and ‘content’ below). This is a version of a view that can be found in Carnap (1959), Ayer (1936), and, maybe, the early Wittgenstein (1922). The notion (...) I propose abstracts away from their favored (but wrong) theories of what meaning is. It is a notion of nonsense that can be appealed to by all semantic frameworks and all theories of what content is, but structurally it is just like e.g. Carnap’s. Nonsense, as I construe it, is accompanied by illusions of thought (and I think that was part of Carnap’s conception as well). 2. Yes. In particular, I examine three arguments for the impossibility of illusion of thought (which on my construal accompanies linguistic nonsense) and they are all unsound. 3. Yes. There might be a lot of nonsense, both in ordinary and theoretical speech. In particular, it is likely that much of contemporary philosophy consists of nonsense. Empirical work is required to determine just how much. 4. The struggle to avoid nonsense (and achieve meaningfulness) is at least as important as the struggle for truth. The avoidance of nonsense is a precondition not just for having a truth value but also for more important properties such as saying something interesting or kind. (shrink)

The paper builds on a methodological idea from experimental philosophy and on findings from psycholinguistics, to develop and defend ordinary language analysis (OLA) as practiced in J.L. Austin’s Sense and Sensibilia. That attack on sense-datum theories of perception focuses on the argument from illusion. Through a case-study on this paradoxical argument, the present paper argues for a form of OLA which is psychologically informed, seeks to expose epistemic, rather than semantic, defects in paradoxical arguments, and is immune to the main (...) objections to ordinary language philosophising, including those arising from the semantic/pragmatics distinction: A key project in current experimental philosophy is to develop psychological explanations of philosophically relevant intuitions that help us determine what warrant thinkers have for accepting them. Psycholinguistic work on the role of stereotypes in verb-comprehension has shown that intuitive judgments can be generated by automatic cognitive processes that duplicate both semantic and pragmatic inferences and are shaped by dominant uses of words. For systematic reasons, philosophers are prone to unwittingly deviate from such dominant uses. Where this happens, they are liable to automatically infer unwarranted conclusions that strike them as intuitively compelling. OLA helps us to determine those dominant uses, to identify unwitting deviations from them, and thus to expose unwarranted intuitions – e.g., in the premises of paradoxical arguments. Ordinary language does not determine the bounds of sense but shapes our leaps of thought. The paper shows how this enables its ‘Austinian’ analysis to contribute to a novel, epistemic, resolution of philosophical paradoxes and problems. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Christopher Norris HOME THOUGHTS FROM ABROAD: DERRIDA, AUSTIN, AND THE OXFORD CONNECTION THERE IS NO philosophical school or tradition that does not carry along with it a background narrative linking up present and past concerns. Most often this selective prehistory entails not only an approving account of ideas that fit in with the current picture but also an effort to repress or marginalize anytíiing that fails so to fit. (...) Bertrand Russell's History Of Western Philosophy is one fairly blatant example of mis strategy at work.1 The story it tells is a Whiggish account of how drinkers managed — against all the odds of metaphysical delusion — to come out at last (with Russell and his peers) on the high plateau oflogical consistency and truth. On the way to this dénouement Russell avails himself ofvarious techniques for pointing up die narrative drift. His coverage takes in all the accredited "major" thinkers, some of whose opinions Russell is hard put to summarize without remarking how nonsensical they appear from a modern (logical) point of view. Elsewhere — as with Leibniz or Kant — he takes the more accommodating line of winnowing out the structures of valid argument and consigning what remains to the history of dead metaphysical abstractions. It is this latter technique that has characterized the approach of analytical philosophers to the history of their discipline. The question is not so much, what did these drinkers mean or knowingly hope to achieve by posing the issues as they did? Rather it is to ask what techniques exist for translating their concerns into an up-to-date idiom based upon certain (mainly linguistic) terms of analytical enquiry. P. F. Strawson's revisionist reading of Kant is probably the best-known example of how such techniques can be used to achieve a distinctively modern understanding of otherwise recalcitrant texts.2 What remains of Kant after this cleaning-up 2 Philosophy and Literature operation is still "metaphysics" of a kind, but relieved of its excess conceptual baggage and couched (as Strawson would claim) in a "descriptive" rather than a "prescriptive" idiom. Thus philosophy comes to terms with its own errant precursors by explaining what they would presumably have said if equipped with die latest analytical tools. The result of such meuiods is to rewrite intellectual history from a standpoint of self-assured logical grasp where present concerns decide what shall count as the relevant or useful aspects ofpast tradition. And the same selective process goes to construct that typecast narrative which treats the "British" and die "Continental" styles of philosophizing as two completely separate, indeed antagonistic lines of descent. Thus it is taken for granted that the two sides are so far apart, with so little in the way of shared methods and assumptions, mat any kind of dialogue is certain to produce mere bafflement or cross-purpose talk. British philosophers with an interest in "Continental" theory feel themselves forced into a marginal role by the highly professionalized ethos that prevails within their discipline. This feeling is only strengthened by their more or less accepting the background mythology that explains how the two "traditions" grew up in a state of hostility often amounting to downright mutual contempt. There are several different versions of this story at present, but they all serve equally to reinforce the sense of incommensurable aims and languages. One (the "ordinary language" version) takes its lead from the later Wittgenstein in arguing that most of the problems that have long vexed philosophers — and continue to vex those "Continental" thinkers — result from dieir use ofa poindess metaphysicaljargon which puts them at odds with the commonsense wisdom of everyday usage. On this account, such thinkers have failed to learn the lesson bequeaüied by a long tradition of misguided speculative thought. They have persisted in errors and delusions of their own creating, hooked on a kind of malign verbal magic — "bewitchment by language," as Wittgenstein described it — which prevents them from seeing the plain sense ofthings. The other exemplary narrative is Uiat which takes not "ordinary language" but logic (or the modern refinements oflogic introduced by philosophers like Frege) as its reference point for deciding which episodes ofprevious or subsequent diought are to...

Abstract: How it is that one's own thoughts can seem to be someone else's? After noting some common missteps of other approaches to this puzzle, I develop a novel cognitive solution, drawing on and critiquing theories that understand inserted thoughts and auditory verbal hallucinations in schizophrenia as stemming from mismatches between predicted and actual sensory feedback. Considerable attention is paid to forging links between the first-person phenomenology of thought insertion and the posits (e.g. efference copy, corollary discharge) of (...) current cognitive theories. I show how deficits in the subconscious mechanisms regulating inner speech may lead to a 'fractured phenomenology' responsible for schizophrenic patients' reports of inserted thoughts and auditory verbal hallucinations. Supporting work on virtual environments is discussed, and lessons concerning the fixity of delusional belief are drawn. (shrink)

As research on mind wandering has accelerated, the construct’s defining features have expanded and researchers have begun to examine different dimensions of mind wandering. Recently, Christoff and colleagues have argued for the importance of investigating a hitherto neglected variety of mind wandering: “unconstrained thought,” or, thought that is relatively unguided by executive-control processes. To date, with only a handful of studies investigating unconstrained thought, little is known about this intriguing type of mind wandering. Across two experiments, we (...) examined, for the first time, whether changes in task demand influence rates of constrained versus unconstrained thoughts. In both experiments, participants completed either an easy (0-back) or hard (2-back) task and responded to intermittently presented thought probes that gauged thought constraint throughout the task. In Experiment 1, we found that participants completing the easy task engaged in unconstrained thoughts more frequently than those completing the difficult task. In Experiment 2, we replicated this result and further demonstrated manipulations of unconstrained thought while also measuring task-relatedness (a common dimension of mind wandering). Finally, exploratory analyses showed associations between constrained thought and age, verbal intelligence, and an assessment of flow (‘deep effortless concentration’), thereby adding further evidence to indicate a dissociation between task-relatedness and constraint. We discuss the methodological and theoretical applications of our findings to the burgeoning field of research on unconstrained thought. (shrink)

The possibility and extent of thought without language have been subject to much controversy. Insight from non- or minimally verbal humans can inform this debate empirically. Since most such individuals are on the autism spectrum, of which they make up a sizable 25–30%, an important connection between language and autism transpires. Here we propose a model which makes sense of this link and explains why the non-verbal human mind, as present evidence suggests, represents a fundamentally different cognitive (...) phenotype. This model views the relevant part of the autism spectrum as reflecting the breakdown of a cognitive phenotype of which language is an inherent element and which will manifest principled limitations in the latter's absence.

In this paper I highlight two noteworthy features of assertions about our desires, and then highlight two ways in which they can mislead us into drawing unwarranted conclusions about desire.

But I suggest that some such assertions are, in this respect, potentially misleading, and have in fact misled authors such (...) as Russ Shafer-Landau, Jack Woods, and Tim Scanlon. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

The principal temptation toward substance dualisms, or otherwise incorporating a question begging homunculus into our psychologies, arises not from the problem of consciousness in general, nor from the problem of intentionality, but from the question of our awareness and understanding of our own mental contents, and the control of the deliberate, conscious thinking in which we employ them. Dennett has called this "Hume's problem". Cognitivist philosophers have generally either denied the experiential reality of thought, as did the Behaviorists, or (...) have taken an implicitly epiphenomenalist stance, a form of dualism. Some sort of mental duality may indeed be required to meet this problem, but not one that is metaphysical or question begging. I argue that it can be solved in the light of Paivio's "Dual Coding" theory of mental representation. This theory, which is strikingly simple and intuitive (perhaps too much so to have caught the imagination of philosophers) has demonstrated impressive empirical power and scope. It posits two distinct systems of potentially conscious representations in the human mind: mental imagery and verbal representation (which is not to be confused with 'propositional' or "mentalese" representation). I defend, on conceptual grounds, Paivio's assertion of precisely two codes against interpretations which would either multiply image codes to match sense modes, or collapse the two, admittedly interacting, systems into one. On this basis I argue that the inference that a conscious agent would be needed to read such mental representations and to manipulate them in the light of their contents can be pre-empted by an account of how the two systems interact, each registering, affecting and being affected by developing associative processes within the other.

Awareness is a personal experience, which is only accessible to the rest of world through interpretation. We set out to identify a neural correlate of visual awareness, using brief subliminal and supraliminal verbal stimuli while measuring cerebral blood flow distribution with H215O PET.

Our results suggest participation of these (...) higher order perceptual and executive cortical structures in visual verbal awareness. (shrink)

The intuitive experience of dreaming is that we “see” something with our mind’s eye and react to it. Indeed, dream formation conceptualizations have often focused on the visual image-to-verbal thought direction of causality, inspired by bottom-up models of perception. However, despite being experienced as external to us, the dream environment is internally generated, meaning that dreams are more like imagination than perception. Dream thoughts (experienced with a sense of agency or selfhood) also affect subsequent dream images (experienced as (...) non-agentive or external to one’s self). Thus, oneiric experiences are made up of reciprocal, continuous, moment-to-moment influences between the dream and the dreamer: visual images and verbal, abstract, or otherwise imageless thoughts. During wakefulness, a dreamlike cognitive processing dynamic of ever-changing meaningful image-thought-image momentary associations coupled with reduced agentive control of images may be present to a greater or lesser extent. Non-agentive visual images as a significant driving force in one’s spontaneous mental activity may relate to individual differences in fantasy proneness, suggestibility, dissociative absorption, or imagination tendencies. This feature carries implications for the field of spontaneous thought. Off-task thinking, or mind-wandering, are non-specific labels that may be used to denote internally generated mentation. Considering the tendency for dreamlike associations may represent a specific distinction, which may be relevant for understanding psychopathology. Whereas some individuals may find themselves distracted by abstract or semantic associations (e.g., verbal self-derogatory inner speech), others may find themselves drawn to intrusive—or alluring—visual images, which may interact significantly with their verbal thoughts and associations and even be experienced with decreased sense of agency. This may occur in obsessive-compulsive disorder, dissociative disorders, or maladaptive daydreaming, suggesting that clinicians need to pay attention to their clients’ spontaneous visual imagery. If a picture is worth a thousand words and seeing is believing, psychologists should be curious of how a visual thinking style may impact mental health. (shrink)

The essays in this volume make it abundantly clear that there is no shortage of disagreement about the plausibility of the simulation theory. As we see it, there are at least three factors contributing to this disagreement. In some instances the issues in dispute are broadly empirical. Different people have different views on which theory is favored by experiments reported in the literature, and different hunches about how future experiments are likely to turn out. In 3.1 and 3.3 we will (...) consider two cases that fall under this heading. With a bit of luck these disputes will be resolved as more experiments are done and more data become available. Faulty arguments are a second source of disagreement. In 3.2 and 3.4 we will set out two dubious arguments advanced by our critics and try to explain exactly why we think they are mistaken. The third source of disagreement is terminological. Terms like "theory-theory," "simulation theory" and a number of others are often not clearly defined, and they are used in different ways by different authors. (Worse yet, we suspect they are sometimes used in different ways by a single author on different occasions). Thus it is sometimes the case that what appears to be a substantive disagreement turns out to be simply a verbal dispute. Moreover, since the labels "theory-theory" and "simulation theory" are each used to characterize a broad range of theories, it may well turn out that some of the theories falling under both headings are correct. In Sections 1 and 2, we will set out a variety of different views for which the labels "theory-theory" and "simulation theory" might be used. As we proceed we'll point out a number of places where disagreements diminish when distinctions among different versions of the theory-theory and the simulation theory are kept clearly in mind.

Wittgenstein's view of philosophy in the Tractatus presupposes that thought may be revealed without remainder in the use of signs. It is commonly held, however, that in the Tractatus he treated thought as logically prior to language. If this view, expressed most lucidly by Norman Malcolm, were correct, Wittgenstein would be inconsistent in holding that thought can be revealed without remainder in the use of signs. I argue that this is not correct. Thought may be prior (...) to language in time but not in logic, for non-verbal symbols must have a logical structure in common with verbal ones. A view comparable with Malcolm's holds that Wittgenstein, under the influence of Schopenhauer, is committed to some form of solipsism. I argue that neither Schopenhauer nor Wittgenstein held any version of solipsism. For both philosophers, subject and object are correlative, so that it is incoherent to affirm the existence of the one without presupposing the existence of the other. (shrink)

Literary narratology has rightly devoted much attention to analysing the source(s) of verbal information about the story world, usually discussed under the label “narration”, and to any agent(s) that present(s) non-verbalized perspectives on it, usually discussed under the label “focalization”. Assessing the identity of narrators and focalizers is crucial for understanding what is going on in the story world. Which narrative agent is in charge? Is the narration and/or focalization layered? If the latter, is there any “colouring” by the (...) higher-level narrative agent of anything said, thought, or experienced by the lower-level agent? Is the information provided trustworthy? Nuanced? Prejudiced? Narration and focalization have supra-medial as well as medium-specific dimensions. Over the past years, the issue of how these concepts function in the medium of comics, which combines visuals and language, has begun to be systematically addressed. This paper aims to show how the visual mode can, on its own or combined with the written-language mode, signal the sources of narration, focalization, and joint narration-and-focalization, as well as distinguish between different levels at which these take place.

The article focuses on the role of Olena Pchilka1 and Lesia Ukrainka in epigraphic embroidery development. Undoubtedly, Olena Pchilka was an ardent proponent of folk art purity. Following from this, there is a tendency to think that she was against all novelty in Ukrainian embroidery. Many researchers and antiquity enthusiasts refer to her authority when arguing against inscriptions on textile as a phenomenon resulting largely from printed cross-stitch on paper. However, not all embroidered verbal texts have been of print (...) origin. Most of them were folkloric texts. What is more, Olena Pchilka to some extent provided her own comment on epigraphic embroidery in approving Lesia Ukrainka’s rushnyk containing the inscription “Oh, my thoughts, my thoughts, woe is with you! Love one another, brethren, love Ukraine”. In modern embroidery, embroideresses reproduce the citation with new connotations of these words, thereby continuing the epigraphic embroidery tradition. The author illustrates the folklorization of oft-cited lines from Taras Shevchenko’s poetry with examples of epigraphic embroidery from her own Interactive Index of Folklore Formulas. (shrink)

For all the differences in the teachings and fate of Franz Rosenzweig and Mikhail Bakhtin, comparing them with one another is extremely instructive and reveals important and often lost meanings of 20th-century philosophy. Bakhtin made his debut in 1929 as the author of Problems of Dostoevsky’s Creative Art, but then went into exile for sufficient years and emerged from oblivion only in the 1960s. Rosenzweig died in 1929 and was almost forgotten for many years. Now, almost a century later, we (...) see in Bakhtin’s philosophy, especially in his early works, and in Rosenzweig’s philosophy very much in common. Both sought to create a new philosophical system that radically rethinks the subject of philosophy. Both went beyond the traditional New European ontology, both recognized the fundamentality of language and language arts in the philosophy of the future, and, finally, both became the creators of the philosophy of dialogue as an important trend in 20th-century thought. For all that, there were many cultural, religious, and intellectual differences between Bakhtin and Rosenzweig. However, consideration of both the commonalities and differences in their philosophical systems is extremely fruitful not only for the cultural history of the 20th century but also for philosophical studies of the future.

This paper disputes the notion, endorsed by much of narrative theory, that the reading of literary narrative is functionally analogous to an act of communication, where communication stands for the transfer of thought and conceptual information. The paper offers a basic typology of the sensorimotor effects of reading, which fall outside such a narrowly communication-based model of literary narrative. A main typological distinction is drawn between those sensorimotor effects pertaining to the narrative qua verbal utterance (verbal presence) (...) and those sensorimotor effects pertaining to the imaginary physical world(s) of the story (direct presence). While verbal presence refers to the reader's vicarious perception of the voices of narrators and characters, direct presence refers to the emulated sensorimotor experience of the imaginary worlds that the narrators' and characters' utterances refer to. The paper further elaborates on how, by which kinds of narrative content and structure, direct presence may be prompted. The final section addresses some of the observational and historical caveats that must be attached to any theoretical inquiry made into the sensorimotor effects of reading. As a preliminary for further research, a few ideas about the model's potential for empirical validation are put forward. A brief, tentative history of the sensorimotor benefits of literary narrative reading is then outlined. (shrink)

This paper explores the effect of different types of incubation task (visual, numerical and verbal) with various levels of attentional focus and cognitive effort (non-demanding, low-demanding and high-demanding) on the resolution of insight problems. The most effective was found to be the low-demanding task (regardless of its nature), which although requiring attentional focus, leaves resources available for the unconscious analytical restructuring process, obtaining a high percentage of success in solving the problem shortly after completion of the incubation task. Overall (...) findings support the hypothesis of Unconscious Analytic Thought (UAT), according to which the restructuring required in insight problem solving implies a covert thinking process that includes a relevant, analytic and goal-oriented search. The findings are discussed in the light of UAT and are compared with the main theories of insight in problem solving. (shrink)

Recently, many philosophers and psychologists have claimed that the explanation that grounds both passivity phenomena in the cognitive domain and passivity phenomena that occur with respect to overt actions is, along broad lines, the same. Furthermore, they claim that the best account we have of such phenomena in both scenarios is the “comparator” account. However, there are reasons to doubt whether the comparator model can be exported from the realm of overt actions to the cognitive domain in general. There is (...) a lingering worry concerning such explanations of thought insertion: the "What is compared to what?" problem. Here I examine two ways to tackle this problem. First: thought insertion consists of the misattribution of strings of inner speech which are not attenuated (thought insertion is thus another name for auditory verbal hallucinations). Second: thought insertion is misattributed inner speech which exhibits the same phenomenological characteristics as normal inner speech. After explaining the types of problem that each of these potential solutions faces, I conclude with a set of open questions that the comparator theorist has to tackle. (shrink)

Odor and color are strongly associated. Numerous studies demonstrate consistent odor‐color associations, as well as effects of color on odor perception and language. Yet, we know little about how these associations arise. Here, we test whether language is a possible mediator of odor‐color associations, specifically whether odor‐color associations are mediated by implicit odor naming. In two experiments, we used an interference paradigm to prevent the verbalization of odors during an odor‐color matching task. If participants generate color associations subsequent to labeling (...) an odor, interfering with verbalization during the task should affect the ability to make color associations. In Experiment 1, contrary to our hypothesis, verbal interference did not affect odor‐color matches. However, since performance accuracy on the verbal interference task was high, it is possible our task did not sufficiently disrupt verbal processing. In Experiment 2, we, therefore, used an active verbal interference task, and still found no difference across interference conditions. Odor naming accuracy, odor familiarity, and odor pleasantness, however, did predict odor‐color matches. This suggests that although color associations are related to semantic factors, they are not generated by recruiting odor labels in the moment. Overall, our results do not provide evidence that language plays an online role in odor‐color associations, instead, they are consistent with the claim that language may have shaped associations during development.

Since the methods employed during teacher-learner interchange are constrained by the internal structure of a discipline, a study of the interaction amongst verbal language, technical language and structure of disciplines is at the heart of the classic problem of transfer in teaching-learning situations. This paper utilizes the analytic method of philosophy to explore aspects of the role of language in mathematics education, and attempts to harmonize mathematical meanings exposed by verbal language and the precise meanings expressed by the (...) mathematics register (MR) formulated in verbal language. While focusing on the integration of language use and meaning construction in mathematics education, the paper explores the relationship between the conceptual understanding revealed by the mathematics register and the procedural knowledge that refers to the mathematical content through ordinary discourse.

IntroductionEspecially in the chronic phase, individuals with traumatic brain injury may still have impairments at the discourse level, even if these remain undetected by conventional aphasia tests. As a consequence, IwTBI may be impaired in conversational behavior and disadvantaged in their socio-communicative participation. Even though handling discourse is thought to be a basic requirement for participation and quality of life, only a handful of test procedures assessing discourse disorders have been developed so far. The MAKRO Screening is a recently (...) developed screening tool designed to assess discourse impairments. The test construction is based on psycholinguistic frameworks and the concept of macro-rules, which refer to cognitive functions responsible for organizing and reducing complex information in discourse.AimThe aim of our study was to investigate discourse processing in IwTBI in different tasks and to assess problems in communicative participation in the post-acute and chronic phase. In this context, we also aimed to analyze the influence of the severity of the initial impairment and the verbal executive abilities on the discourse performance. Additionally, the impact of macrolinguistic discourse impairments and verbal fluency on perceived communicative participation was targeted in our analysis.MethodsData from 23 IwTBI and 23 healthy control subjects have been analyzed. They completed two subtests of the MAKRO screening: Text production and Inferences. Discourse performance was examined in relation to measures of semantic fluency and verbal task-switching. Socio-communicative problems were evaluated with the German version of the La Trobe Communication Questionnaire.ResultsIwTBI showed lower test results than the control group in the two subtests of the MAKRO-Screening. Difficulties in picture-based narrative text production also indicated greater perceived difficulties in communicative participation. We also found that the subject’s performance on the MAKRO-Screening subtests can partly be explained by underlying dysexecutive symptoms and the severity of their injury. The preliminary results of our study show that cognitive-linguistic symptoms in IwTBI are also evident in the chronic phase. These can be detected with procedures referring to the discourse level, such as the MAKRO-Screening. The assessment of discourse performance should be an integral part in the rehabilitation of IwTBI in order to detect cognitive-linguistic communication disorders and to evaluate their impact on socio-communicative participation.
