Over 100 million Americans suffer from chronic pain, which causes more disability than any other medical condition in the United States at a cost of $560–$635 billion per year. Opioid analgesics are frequently used to treat CP. However, long term use of opioids can cause brain changes such as opioid-induced hyperalgesia that, over time, increase pain sensation. Also, opioids fail to treat complex psychological factors that worsen pain-related disability, including beliefs about and emotional responses to pain. Cognitive behavioral therapy can (...) be efficacious for CP. However, CBT generally does not focus on important factors needed for long-term functional improvement, including attainment of personal goals and the psychological flexibility to choose responses to pain. Acceptance and Commitment Therapy has been recognized as an effective, non-pharmacologic treatment for a variety of CP conditions. However, little is known about the neurologic mechanisms underlying ACT. We conducted an ACT intervention in women with chronic musculoskeletal pain. Functional magnetic resonance imaging data were collected pre- and post-ACT, and changes in functional connectivity were measured using Network-Based Statistics. Behavioral outcomes were measured using validated assessments such as the Acceptance and Action Questionnaire, the Chronic Pain Acceptance Questionnaire, the Center for Epidemiologic Studies Depression Scale, and the NIH Toolbox Neuro-QoLTM scales. Results suggest that, following the 4-week ACT intervention, participants exhibited reductions in brain activation within and between key networks including self-reflection, emotion, and cognitive control. These changes in connectivity strength were correlated with changes in behavioral outcomes including decreased depression and pain interference, and increased participation in social roles. This study is one of the first to demonstrate that improved function across the DMN, SN, and FPN may drive the positive outcomes associated with ACT. This study contributes to the emerging evidence supporting the use of neurophysiological indices to characterize treatment effects of alternative and complementary mind-body therapies. (shrink)

A challenge of performing research in the paediatric emergency and acute care setting is obtaining valid prospective informed consent from parents. The ethical issues are complex, and it is important to consider the perspective of participants, health care workers and researchers on research without prospective informed consent while planning this type of research. We performed a systematic review according to PRISMA guidelines, of empirical evidence relating to the process, experiences and acceptability of alternatives to prospective informed consent, in the paediatric (...) emergency or acute care setting. Major medical databases and grey sources were searched and results were screened and assessed against eligibility criteria by 2 authors, and full text articles of relevant studies obtained. Data were extracted onto data collection forms and imported into data management software for analysis. Thirteen studies were included in the review consisting of nine full text articles and four abstracts. Given the heterogeneity of the methods, results could not be quantitatively combined for meta-analysis, and qualitative results are presented in narrative form, according to themes identified from the data. Major themes include capacity of parents to provide informed consent, feasibility of informed consent, support for alternatives to informed consent, process issues, modified consent process, child death, and community consultation. Our review demonstrated that children, their families, and health care staff recognise the requirement for research without prior consent, and are generally supportive of enrolling children in such research with the provisions of limiting risk, and informing parents as soon as possible. Australian data and perspectives of children are lacking and represent important knowledge gaps. (shrink)

Neural substrates of fatigue in traumatic brain injury are not well understood despite the considerable burden of fatigue on return to productivity. Fatigue is associated with diminishing performance under conditions of high cognitive demand, sense of effort, or need for motivation, all of which are associated with cognitive control brain network integrity. We hypothesize that the pathophysiology of TBI results in damage to diffuse cognitive control networks, disrupting coordination of moment-to-moment monitoring, prediction, and regulation of behavior. We investigate the cingulo-opercular (...) and frontoparietal networks, which are engaged to sustain attention for task and maintain performance. A total of 61 individuals with mild TBI and 42 orthopedic control subjects participated in functional MRI during performance of a constant effort task requiring altering the amount of effort utilized to manually squeeze a pneumostatic bulb across six 30-s trials. Network-based statistics assessed within-network organization and fluctuation with task manipulations by group. Results demonstrate small group differences in network organization, but considerable group differences in the evolution of task-related modulation of connectivity. The mild TBI group demonstrated elevated CO connectivity throughout the task with little variation in effort level or time on task, while CO connectivity diminished over time in controls. Several interregional CO connections were predictive of fatigue in the TBI group. In contrast, FP connectivity fluctuated with task manipulations and predicted fatigue in the controls, but connectivity fluctuations were delayed in the mild traumatic brain injury group and did not relate to fatigue. Thus, the mTBI group’s hyper-connectivity of the CO irrespective of task demands, along with hypo-connectivity and delayed peak connectivity of the FP, may allow for attainment of task goals, but also contributes to fatigue. Findings are discussed in relation to performance monitoring of prediction error that relies on internal cues from sensorimotor feedback during task performance. Delay or inability to detect and respond to prediction errors in TBI, particularly evident in bilateral insula-temporal CO connectivity, corresponds to day-to-day fatigue and fatigue during task performance.

This article is a reexamination of the author’s understanding of pedagogy, aimed at developing an increased awareness of the provinciality, limits and blind spots of the pedagogy and knowledge systems of colonial modernity. It engages with particular Indigenous epistemological theorisations of non-human agency, with Haraway’s notion of multispecies entanglement, and with the Australian Great Barrier Reef in an inquiry aimed at noticing absences and hauntings of pedagogies of modernity, including the absence of ways of knowing and being without separability and (...) determinacy and the damage that has come of this. This opens space for contemplating separability and determinacy as ontological difficulties contributing to socio-ecological crises of our time. The article is intended as a move by the author toward developing greater capacity to stay with the trouble of educating and living on a damaged planet that is fast becoming uninhabitable. (shrink)

Ordinary discourse is filled with discussions about ‘sexual orientation’. This discourse might suggest a common understanding of what sexual orientation is. But even a cursory search turns up vastly differing, conflicting, and sometimes ethically troubling characterizations of sexual orientation. The conceptual jumble surrounding sexual orientation suggests that the topic is overripe for philosophical exploration. This paper lays the groundwork for such an exploration. In it, I offer an account of sexual orientation – called ‘Bidimensional Dispositionalism’ – according to which sexual (...) orientation concerns what sex[es] and gender[s] of persons one is disposed to sexually engage, and makes no reference to one’s own sex and gender.

Most clinical neurofeedback studies based on functional magnetic resonance imaging use the patient's own neural activity as feedback. The objective of this study was to create a subject-independent brain state classifier as part of a real-time fMRI neurofeedback system that can guide patients with depression in achieving a healthy brain state, and then to examine subsequent clinical changes. In a first step, a brain classifier based on a support vector machine was trained from the neural information of happy autobiographical imagery (...) and motor imagery blocks received from a healthy female participant during an MRI session. In the second step, 7 right-handed female patients with mild or moderate depressive symptoms were trained to match their own neural activity with the neural activity corresponding to the “happiness emotional brain state” of the healthy participant. The training was carried out using the rt-fMRI NF system guided by the brain-state classifier we had created. Thus, the informative voxels previously obtained in the first step, using SVM classification and Effect Mapping, were used to classify the Blood-Oxygen-Level Dependent activity of the patients and converted into real-time visual feedback during the neurofeedback training runs. Improvements in the classifier accuracy toward the end of the training were observed in all the patients [Session 4–1 Median = 6.563%; Range = 4.10–27.34; Wilcoxon Test, 2-tailed p = 0.031]. Clinical improvement also was observed in a blind standardized clinical evaluation [HDRS CE2-1 Median = 7; Range 2 to 15; Wilcoxon Test, 2-tailed p = 0.016], and in self-report assessments [BDI-II CE2-1 Median = 8; Range 1–15; Wilcoxon Test, 2-tailed p = 0.031]. In addition, the clinical improvement was still present 10 days after the intervention [BDI-II CE3-2_Median = 0; Range −1 to 2; Wilcoxon Test, 2-tailed p = 0.50/ HDRS CE3-2 Median = 0; Range −1 to 2; Wilcoxon Test, 2-tailed p = 0.625]. Although the number of participants needs to be increased and a control group included to confirm these findings, the results suggest a novel option for neural modulation and clinical alleviation in depression using noninvasive stimulation technologies.

In recent years, many school librarians have been scrambling to build and expand their graphic novel collections to meet the large and growing demand for these materials. For the purposes of this study, the term graphic novels refers to volumes in which the content is provided through sequential art, including fiction, nonfiction, and biographical material. As the library field has not yet arrived at a set of best practices or guidelines for institutions working to classify and catalog graphic novels, this (...) study seeks to record the ways in which school librarians are handling these materials as well as issues and questions at the forefront of their minds. A survey of school librarians in the United States revealed that almost all of them collect fiction and nonfiction graphic novels, while 67% collect manga. Most respondents indicated that they are partly or solely responsible for the cataloging and classification decisions made in their media centers. For classification purposes, most have elected to create separate graphic novel collections to house their fictional graphic novels. Some include nonfiction graphic novels in this section, while others create a nonfiction graphic novel collection nearby or shelve nonfiction graphic novels with other items that deal with similar subject matter. Many school librarians express uncertainty about how best to catalog and classify longer series, adapted classics, superhero stories, and the increasing number and variety of inventive titles that defy categorization. They also struggle with inconsistent vendor records and past practices and suffer from a lack of full confidence in their knowledge of how to best classify and catalog graphic novels so that they are both searchable in the library catalog and easily accessible on the shelves.

Presenting a landmark in linguistics and cognitive science, Ray Jackendoff proposes a new holistic theory of the relation between the sounds, structure, and meaning of language and their relation to mind and brain. Foundations of Language exhibits the most fundamental new thinking in linguistics since Noam Chomsky's Aspects of the Theory of Syntax in 1965—yet is readable, stylish, and accessible to a wide readership. Along the way it provides new insights on the evolution of language, thought, and communication.

What responsibility do individuals bear for structural injustice? Iris Marion Young has offered the most fully developed account to date, the Social Connections Model. She argues that we all bear responsibility because we each causally contribute to structural processes that produce injustice. My aim in this article is to motivate and defend an alternative account that improves on Young’s model by addressing five fundamental challenges faced by any such theory. The core idea of what I call the “Role-Ideal Model” is (...) that we are each responsible for structural injustice through and in virtue of our social roles, i.e. our roles as parents, colleagues, employers, citizens, etc., because roles are the site where structure meets agency. In short, the Role-Ideal Model explains how individual action contributes to structural change, justifies demands for action from each particular agent, specifies what kinds of acts should be undertaken, moderates between demanding too much and too little of individual agents, and provides an account of the critical responses appropriate for holding individuals accountable for structural injustice.

What do consumers do with their used clothing, books, and children’s toys? In this research, we introduce metaphoric “fresh start” messaging as an effective tactic to encourage consumers to engage in environmentally sustainable actions of donating used products for remanufacture or reuse. Drawing on conceptual metaphor theory and construal theory, we contrast metaphoric “fresh start” messaging with dominant “reduce waste” and “recycle” non-metaphoric environmental messages. Across six experimental studies, metaphoric “fresh start” messaging is more effective in increasing environmentally sustainable actions, (...) including used product donations and donation intentions. The effectiveness of metaphoric “fresh start” messaging is grounded in its activation of abstract thinking as “rebirth associations,” thoughts around new beginnings, renewal, and new life. We examine the effectiveness of metaphoric “fresh start” (vs. non-metaphoric environmental) messaging with the use of “fresh start” temporal landmarks (New Year’s Day and Earth Day) and find that metaphoric “fresh start” messaging, with or without these temporal landmarks, is more effective in triggering abstract thinking as “rebirth associations.” Our work substantiates the power of metaphoric “fresh start” messaging in encouraging consumers’ environmentally sustainable actions and has significant implications for the use of conceptual metaphors in marketing messages.

A protein kinase cascade is involved in the action of some mitogens. The cascade begins with receptor tyrosine kinase activation by growth factors. The resulting signal is transmitted into cells via phospholipid metabolism which produces a variety of second messengers and by intracellular protein kinase activation. The signal is then propagated and disseminated via a network of other proteln kinases and protein phosphatases. Recent research suggests that ribosomal protein S6 kinase and casein kinase II are two important elements in the (...) kinase cascade that leads to the initiation of growth. The nature and some properties of these hitherto lesser known enzymes is considered. (shrink)

People who inject drugs are often the target of stigma that puts this already at-risk group at greater risk of harm. Past research has shown that holding stigmatizing views of people who inject drugs increases risky behaviors and is a barrier to their engagement in important medical and public health interventions. One explanation is that the negativity surrounding the group causes increased levels of anticipated emotional exhaustion, discouraging positive engagement. However, there has been minimal research focused on addressing this negativity (...) to reduce levels of held stigma against people who inject drugs. We hypothesized that giving people an imagined positive contact exercise about people who inject would lead to a reduction in stigma, since exposure to positive empathy may create new mental associations between stigmatized groups and more positive emotions and experiences. Secondarily, we hypothesized that positive empathy strategies would be more effective than traditional informational or learning based techniques, and that the latter would be more effective than a control condition. Our sample consisted of 375 participants recruited online. Participants were assigned to one of three study conditions: a positive empathy condition, an informational learning condition, or a control condition, and completed a posttest social distance measure. Results demonstrated that subjects exposed to the positive empathy stigma reduction condition experienced a significant reduction in held stigma while participants exposed to traditional informational learning techniques showed no significant reduction in held stigma. Positive empathy-based stigma interventions should be further researched as a promising avenue to reduce the effects of drug-related stigma. (shrink)

Nietzsche is usually presumed to be an atheist because of his proclaimation that God is dead. This dissertation argues, however, that the death of God is not atheistic but theistic, for Nietzsche's concept of Dionysus, Will to Power itself, entails an implicit commitment to theism. ;Chapter One indicates the enigmatic and nuanced quality of Nietzsche's style. Nietzsche wears masks. In order to decipher these masks with respect to the problem of God, six criteria of the traditional theistic understanding of God (...) are established. These six criteria are: Dionysus is eternal. He is the creative source of the world and man. The world and man exemplify the presence of Dionysus and yet they are not exhaustive of Him. Therefore Dionysus, as more than the world, can be spoken of as "other" than man and the world. This "otherness" entails a relationship between Dionysus and man/world. This relationship is not determinative of Dionysus. Man and world are an experiment on Dionysus' behalf; one that may "terminate," although Dionysus himself will not. ;Chapter Two sets out to formulate and expound upon the first four criteria of theism. This sets down the basic ontology. ;Chapter Three sets forth the problem of nihilism. Nihilism is the result of the death of God. ;Chapter Four discusses the relation of nihilism to morality. For Nietzsche, the moralization of life, and in particular the moralization of God, has led to God's death. Thus this chapter indicates the fifth criterion of theism, i.e., man's relation to God. ;Chapter Five sets out to decode hermeneutically the various masks that Nietzsche wears in reference to the problem of atheism. This chapter demonstrates how Nietzsche's own overt atheistic statements are proclaimations of iconotrophy, not godlessness. ;Chapter Six explicates Nietzsche's positive philosophy of God. This philosophy of God is formulated in terms of The Text of the Divine, God as Non-evaluatable, God and Eschatology, God and the Problem of Causality. Accordingly, this chapter deliniates the sixth criterion of theism, i.e., God's relationship to man. (shrink)

Emotion recognition skills and the ability to understand the mental states of others are crucial for normal social functioning. Conversely, delays and impairments in these processes can have a profound impact on capability to engage in, maintain, and effectively regulate social interactions. Therefore, this study aimed to compare the performance of 42 autistic children, 45 unaffected siblings, and 41 typically developing controls on the Affect Recognition and Theory of Mind subtests of the Developmental Neuropsychological Assessment Battery. There were no significant (...) differences between siblings and TD controls. Autistic children showed significantly poorer performance on AR when compared to TD controls and on TOM when compared to both TD controls and unaffected siblings. An additional comparison of ASD, unaffected sibling and TD control subsamples, matched on full-scale IQ, revealed no group differences for either AR or TOM. AR and TOM processes have received less research attention in siblings of autistic children and remain less well characterized. Therefore, despite limitations, findings reported here contribute to our growing understanding of AR and TOM abilities in siblings of autistic children and highlight important future research directions.

In a continuation of the conversation with Fitch, Chomsky, and Hauser on the evolution of language, we examine their defense of the claim that the uniquely human, language-specific part of the language faculty (the “narrow language faculty”) consists only of recursion, and that this part cannot be considered an adaptation to communication. We argue that their characterization of the narrow language faculty is problematic for many reasons, including its dichotomization of cognitive capacities into those that are utterly unique and those (...) that are identical to nonlinguistic or nonhuman capacities, omitting capacities that may have been substantially modified during human evolution. We also question their dichotomy of the current utility versus original function of a trait, which omits traits that are adaptations for current use, and their dichotomy of humans and animals, which conflates similarity due to common function and similarity due to inheritance from a recent common ancestor. We show that recursion, though absent from other animals’ communications systems, is found in visual cognition, hence cannot be the sole evolutionary development that granted language to humans. Finally, we note that despite Fitch et al.’s denial, their view of language evolution is tied to Chomsky’s conception of language itself, which identifies combinatorial productivity with a core of “narrow syntax.” An alternative conception, in which combinatoriality is spread across words and constructions, has both empirical advantages and greater evolutionary plausibility. q 2005 Elsevier B.V.

We argue that the claim that essence-based causal explanations emerge, hydra-like, from an inherence heuristic is incomplete. No plausible mechanism for the transition from concrete properties, or cues, to essences is provided. Moreover, the fundamental shotgun and storytelling mechanisms of the inherence heuristic are not clearly enough specified to distinguish them, developmentally, from associative or causal networks.

The slogan “Do Your Own Research” (DYOR) is often invoked by people who are distrustful, even downright sceptical, of recognized expert authorities. While this slogan may serve various rhetorical purposes, it also expresses an ethic of inquiry that valorises independent thinking and rejects uncritical deference to recognized experts. This paper is a qualified defence of this ethic of inquiry in one of the central contexts in which it might seem attractive. I use several case studies of patient activist groups to (...) argue that these groups often engage in valuable independent research that advances biomedical knowledge. In doing so they demonstrate the value of “lay expertise” and the epistemic as well as political necessity of not simply deferring to recognized experts. I also give some reasons why patient activist groups often produce valuable biomedical knowledge: they are examples of what I call “research collectives”. Research collectives are research communities that differ from the traditional research communities we find in universities and research institutes in that their members typically lack formal relevant scientific credentials and training. But they are similar in that they have internal structures—training procedures, norms of discussion, venues for holding discussions—that facilitate the production of knowledge. I finish by suggesting that future research into the differences and similarities between research collectives and traditional research communities is required. (shrink)

This paper explores the distinction between active and passive powers. Interest in the distinction has recently been revived in some quarters of the philosophy of action as some have sought to elucidate the distinction between action and passion (the changes that happen to a substance) in terms of the former (Hyman, 2015; Mayr, 2011; Lowe 2013). If there is a distinction between active and passive powers, parallel to the distinction between action and passion, what is it? In this paper, I (...) distinguish two ways of drawing it. According to the first one, active and passive powers are distinguished by the ways in which their manifestations come about. According to the second, they are distinguished by their directedness, i.e. what they are powers to do. Both accounts are examined and the latter is defended against the former. I argue that active powers are powers to alter, modify, corrupt or change something. (shrink)

I argue that if intentions are what Grice, and most contemporary action theorists, take them to be, they are inessential for acts of speaker meaning. More specifically, my primary aim is to show that the consensus view of speaker meaning is in deep tension with certain plausible, and widely accepted, cognitive constraints on rational intention pertaining to an agent’s assessment of her prospects of achieving her goal. My secondary aim is to offer an initial case for thinking that the best (...) way to resolve this tension is to give up the claim that meaning is fundamentally a matter of intention. In pursuing this strategy, we will see some of the potential benefits of Bratman’s (1987) work on intentions, plans, and practical reasoning for the theory of meaning, including some interesting consequences of his rejection of the so-called ‘Simple View’ on which we intentionally do only those things that we specifically intend to do. Moreover, our discussion will help to illustrate how some familiar tools from decision theory might find new use in discussions of meaning and communication. (shrink)

Alfred Tarski’s work on truth has played such a central role in the discourse on truth that most coming to it for the first time have probably already heard a great deal about what is said there. Unfortunately, since the work is largely technical and Tarski was only tan- gentially philosophical, a certain incautious assimilation dominates many philosophical discussions of Tarski’s ideas, and so, examining Tarski on the concept of truth is in many ways an act of unlearning. -/- In (...) this paper I focus on those key ideas in Tarski’s work that have made a lasting impact on the philosophical discourse. These are the notions of T-sentence, Convention T, Tarskian truth definition, and Tarski’s general limiting theses on the expressibility and definability of truth. Though these ideas are in name familiar, we will seek in this essay to uncover and remove certain widespread misunderstandings of each. Tarski’s name also features prominently in discussions of the liar paradox, so we will take time out to explain Tarski’s connection to this ancient puzzle. (shrink)

There is an ongoing debate in the ontology of action about whether actions are processes, events, relations, or sui generis entities. This paper focuses on the process view, the view that actions are processes. I challenge it in two ways. First, I argue that some actions are not processes because their performance need not be associated with or accompanied by a process. Second, I critically discuss three main arguments that have been advanced to support the process view. My view, the (...) pluralist view, is that process-theorists are right to hold that certain actions are processes, but wrong to maintain that every action is a process: activities are processes, acts are not, and some acts are composed of a process whereas others are not.

Dialectics is the logic of estrangement. Self-relating negativity, which is at once every difference and its overcoming, is the pulse of dialectics. But what is this self-estranging sameness? For Hegel, the idealist, it is “the absolute concept.” It is more difficult to say what it is for Marx, who is supposed to be a materialist. If Marx were merely relocating self-estranging sameness from the concept to human “genus-being” (Gattungswesen), understood as a historically variable “ensemble of social relations,” this ensemble would (...) harbour a potentiality to become that is at once enabled and disabled by the social divisions of labour and class that they have generated. This interpretation is vitiated by an ambiguity in its invocation of potentiality. If we flatten human genus-being onto historically variable social relations, there is no latency left in it which could be said to be unactualized by existing social practices. But if some aspect of genus-being is held in reserve as an unactualized potential, we risk re-substantializing it as an a-historical essence. It is this ambiguity that leads Marx’s critics to accuse him of invoking a transcendent conception of human essence despite his insistence that this essence is a function of historically variable social relations. I want to parry this criticism by suggesting that Marx’s materialism requires Hegel’s self-estranging sameness in order to dissolve the apparent dichotomy between immanence and transcendence in the potency ascribed to practice. Estrangement and de-estrangement, compulsion and freedom, are not separable moments but twin facets of the same movement. The prospect of de-estrangement emerges only by retrospecting an enabling estrangement. (shrink)

It has recently been argued that our use of vague language poses an intractable problem for any account of content and communication on which (i) the things we assert are propositions and (ii) understanding an assertion requires recognizing which proposition the speaker asserted. John MacFarlane has argued that this problem concerning vague language is itself a species of an even more general problem for such traditional accounts—the problem posed by “felicitous” underspecification. Repurposing certain ideas from Allan Gibbard, MacFarlane offers a (...) novel theory of vagueness, plan-expressivism, as an account that can handle both vagueness and such underspecification in communication. In this paper, I argue that despite its many virtues, plan-expressivism fails as a general account of meaning and communication. In particular, I show that when it comes to the problem of felicitous underspecification, plan-expressivism fares no better than the more traditional accounts of content and communication it is intended to replace. Along the way, I argue that the problem of felicitous underspecification puts considerable pressure on an assumption that is at the core of both plan-expressivism and the accounts of its more traditionalist rivals – namely, that in cases of successful linguistic communication, we must always be able to find something – whether a propositional content or a conversational update – that the speaker is intending to share with her audience.

Two experiments using a realistic version of the selection task examined the relationship between participants' probability estimates of finding a counter example and their selections. Experiment 1 used everyday categories in the context of a scenario to determine whether or not the number of instances in a category affected the estimated probability of a counter-example. Experiment 2 modified the scenario in order to alter participants' estimates of finding a specific counter-example. Unlike Kirby 1994a, but consistent with his proposals, both studies (...) showed that probability estimates significantly predicted selection. Overall results point to the value of understanding selections in terms of their subjective expected utility. (shrink)

The question of the meaning of life has long been thought to be closely intertwined with that of the existence of God. I offer a new theistic, anti-naturalist argument from the meaning of life. It is argued that the desire for life is irrational on naturalism, since there would be no good reason to believe that life is worthwhile on the whole if naturalism were true. As I show, the same cannot be argued of theism. Since it is clear that (...) the desire for life is not irrational, it is concluded that we have strong reason to prefer theism over naturalism.

Framed in psychological terms, the basic question of linguistic theory is what is stored in memory, and in what form. Traditionally, what is stored is divided into grammar and lexicon, where grammar contains the rules and the lexicon is an unstructured list of exceptions. We develop an alternative view in which rules of grammar are simply lexical items that contain variables, and in which rules have two functions. In their generative function, they are used to build novel structures, just as (...) in traditional generative linguistics. In their relational function, they capture generalizations over stored items in the lexicon, a role not seriously explored in traditional linguistic theory. The result is a highly structured lexicon with rich patterns among stored items. We further explore the possibility that this sort of structuring is not specific to language, but appears in other cognitive domains as well, such as the structure of physical objects, of music, and of geographical and social knowledge. The differences among cognitive domains do not lie in this overall texture, but in the materials over which stored relations are defined. The challenge is to develop theories of representation in these other domains comparable to that for language. (shrink)

Within cognitive science, language is often set apart (as it is in the present volume) from perception, action, learning, memory, concepts, and reasoning. Yet language is intertwined with all of them. Language perception is a kind of perception; language production is a kind of action. Vocabulary and grammar are learned and stored in long-term memory. As novel utterances are perceived or produced, they are built up in working memory. Concepts are most often studied in the context of word meanings; reasoning (...) is most often studied in the context of inferring one sentence from another. (shrink)

John McDowell and Wilfrid Sellars respectively intend to develop a conception of the relationship between mind and world that must subvert a fundamental dilemma between the Myth of the Given and Coherentism: both are committed to the “transcendental task” of accounting for the way in which conceptual activity is directed towards a reality that is not a mere reflection of it. This article focuses on a divergence between their respective conceptions of this transcendental task. According to McDowell, this task involves (...) accounting for the intentional properties of experience in terms of the actualization of semantic properties: a central thesis of Mind and World is that thought and reality meet in the realm of sense if we are to avoid the Myth of the Given. On the other hand, Sellars argues that in order to give an adequate account of the transcendental task, we need to leave the realm of sense. The argument defended in this article is that the central thesis of Mind and World threatens to make McDowell fall back into a (sophisticated) form of coherentism: the actualization of semantic properties has, according to Sellars, only limited explanatory scope to account for the intentionality of experience. -/- .

This paper presents a phenomenon of colloquial English that we call Contrastive Reduplication (CR), involving the copying of words and sometimes phrases as in It’s tuna salad, not SALAD-salad, or Do you LIKE-HIM-like him? Drawing on a corpus of examples gathered from natural speech, written texts, and television scripts, we show that CR restricts the interpretation of the copied element to a ‘real’ or prototypical reading. Turning to the structural properties of the construction, we show that CR is unusual among (...) reduplication phenomena in that whole idioms can be copied, object pronouns are often copied (as in the second example above), and inflectional morphology need not be copied. Thus the ‘scope’ of CR cannot be defined in purely phonological terms; rather, a combination of phonological, morphosyntactic, syntactic, and lexical factors is involved. We develop an analysis within the parallel architecture framework of Jackendoff (1997, 2002), whereby CR is treated as a lexical item with syntactic and semantic content and reduplicative phonology. We then sketch an alternative analysis, based on current assumptions within the Minimalist Program, which involves movement into a focus-like position with both the head and the tail of the resulting chain spelled out.
