Francois Recanati’s Mental Files presents a picture of the mind on which mental representations are indexical and transparent. I dispute this picture: there is no clear case for regarding mental representations as indexical, and there are counterexamples to transparency.

In this paper, I argue that the theory of mental files can provide a unitary cognitive account of how names and singular terms work in fiction. I will suggest that the crucial notion we need is not the one of regular file, i.e., a file whose function is to accumulate information that we take to be about a single object of the outside world, but the notion of indexed file, i.e., a file that stands, in the subject’s mind, for (...) another subject’s file about an object. When we read a novel containing the name of an individual, we acquire (fictional) information about that individual and we store those pieces of information into an indexed file. If the name also refers to a real individual outside the context of fiction, the indexed file is linked with the pre-existing regular file that we have about such individual. Otherwise, the indexed file is linked to a regular file referring to an abstract object, namely the fictional entity itself. (shrink)

Our paper discusses Recanati’s application of the mental files apparatus to reports of beliefs and other attitudes. While mental files appear early on in Recanati’s work on belief-reports, his latest book introduces the concept of indexed files (a.k.a. vicarious files) and puts it to work to explain how we can report other people’s attitudes and to account for opacity phenomena. Our goal is twofold: we show that the approach in Recanati’s Mental Files (Oxford: Oxford University Press, 2012) (...) departs significantly from his earlier proposals as well as from the very spirit of truth-conditional pragmatics; and we argue that the indexed files approach, qua an attempt to provide a semantics for belief-reports, is untenable. -/- .

Accounts for referential communication (and especially communication by means of definite descriptions and indexicals) in the mental file framework.

This book is a sequel to Recanati’s Mental Files (OUP 2012), and pursues the exploration of the mental file framework for thinking about concepts and singular reference. Mental files are based on 'epistemically rewarding' relations to objects in the environment. Standing in such relations to objects puts the subject in a position to gain information regarding them—information which goes into the file based on the relevant relation. Files do not merely store information about objects, however. They refer (...) to them and serve as singular terms in the language of thought, with a relational (nondescriptivist) semantics. Crucially, files also play the role of ‘modes of presentation’. They are used to account for cognitive significance phenomena illustrated by so-called ‘Frege cases’. This book considers what happens to mental files in a dynamic setting. Mental files are construed as both continuants (dynamic files) and as time-slices thereof (static files). Dynamic files are needed to account for confusion, recognition and tracking. The book considers what happens to the relation of coreference de jure, central to the functional characterization of files, when one adopts a dynamic perspective. Only a weak form of coreference de jure is said to hold between stages of the same dynamic file. The second part of the book argues that communication involves interpersonal dynamic files. Special attention is paid to the communication of indexical thoughts (de se contents), and to communication using proper names. (shrink)

Papineau-David_Doubts-about-indexicality.

What characterizes indexical thinking is the fact that the modes of presentation through which one thinks of objects are context-bound and perspectival. Such modes of presentation, I claim, are mental files presupposing that we stand in certain relations to the reference : the role of the file is to store information one can gain in virtue of standing in that relation to the object. This raises the communication problem, first raised by Frege : if indexical thoughts are context-bound and (...) relation-based, how is it possible to communicate them to those who are not in the same context and do not stand in the right relations to the object? Following Frege, I argue that the solution comes from an important distinction between linguistic and psychological modes of presentation. Psychological modes of presentation are mental files. They are perspectival and context-bound. But linguistic modes of presentation are fixed by the conventions of the language and they are shared by the language users. They are public and serve to coordinate mental files in communication by constraining them to contain the piece of information they encode. In this way communication takes place even though the indexical thoughts entertained by the speaker are, in some sense, private and cannot be shared by the audience. (shrink)

Over the past fifty years the philosophy of language and mind has been dominated by a nondescriptivist approach to content and reference. This book attempts to recast and systematize that approach by offering an indexical model in terms of mental files. According to Recanati, we refer through mental files, the function of which is to store information derived through certain types of contextual relation the subject bears to objects in his or her environment. The reference of a file (...) is determined relationally, not satisfactionally, so a file is not to be equated to the body of (mis-)information it contains. Mental files are the mental equivalent of singular terms, and the reference of linguistic expressions is inherited from that of the files we associate with them. On this approach, mental files, the vehicles of singular thought, do all the work of so-called 'modes of presentation' in Fregean and neo-Russellian theories. (shrink)

Background: The brief generic Multicultural Quality of Life Index is a culturally informed self-report 10-item questionnaire used to measure health-related quality of life. QoL is an important outcome measure in guiding healthcare and is held as a substantial parameter to evaluate the effectiveness of healthcare. Attention Deficit Hyperactivity Disorder in children might negatively influence the parents’ QoL. Having a validated questionnaire to measure QoL for this population will therefore be a vital first step in guiding healthcare for parents of children (...) with ADHD. We aimed to examine the reliability and validity of the Norwegian version of the MQLI in a sample of parents of children with ADHD.Methods: In a cross-sectional study, 128 parents of children with ADHD were recruited from four outpatient clinics within the Child and Adolescents Mental Health Services in Norway. They completed the MQLI along with an alternative well-being scale, the Five-item World Health Organization Well-being Index, and a form including demographic variables. Reliability and validity of the MQLI were examined. We conducted a factor analysis and calculated internal consistency and the correlation between the MQLI and the WHO-5.Results: Factor analysis of the parents reported MQLI yielded a one-factor solution. For the MQLI, Cronbach’s alpha was 0.73. The correlation between the two measures of MQLI and WHO-5 was high, reflecting convergent validity since the association between the two measures was strong.Conclusion: Results from this study support the reliability and validity of the Norwegian version of the MQLI for assessment of quality of life in parents of children with ADHD with good psychometric properties. Study findings support the use of the questionnaire in CAMHS. (shrink)

Gestures can serve as external representations of abstract concepts which may be otherwise difficult to illustrate. Gestures often accompany verbal statement as an embodiment of mental models that augment the communication of ideas, concepts or envisioned shapes of products. A gesture is also an indicator of the subject and context of the issue under discussion. We argue that if gestures can be identified and formalized they can be used as a knowledge indexing and retrieval tool and can prove to (...) be useful access point into unstructured digital video data. We present a methodology and a prototype, called I-Gesture that allows users to (1) define a vocabulary of gestures for a specific domain, (2) build a digital library of the gesture vocabulary, and (3) mark up entire video streams based on the predefined vocabulary for future search and retrieval of digital content from the archive. I-Gesture methodology and prototype are illustrated through scenarios where it can be utilized. The paper concludes with results of evaluation experiments with I-Gesture using a test bed of design-construction projects. (shrink)

This book argues that there is a common cognitive mechanism underlying all indexical thoughts, in spite of their seeming diversity. Indexical thoughts are mental representations, such as beliefs and desires. They represent items from a thinker's point of view or her cognitive perspective. We typically express them by means of sentences containing linguistic expressions such as 'this ' or 'that ', adverbs like 'here', 'now', and 'today', and the personal pronoun 'I'. While generally agreeing that representing the world from (...) a thinker's cognitive perspective is a key feature of indexical thoughts, philosophers disagree as to whether a thinker's cognitive perspective can be captured and rationalized by semantic content and, if so, what kind of content this is. This book surveys competing views and then advances its own positive account. Ultimately, it argues that a thinker's cognitive perspective - or her indexical point of view - is to be explained in terms of the content that is believed and asserted as the only kind of content that there is which thereby serves as the bearer of cognitive significance. The Indexical Point of View will be of interest to philosophers of mind and language, linguists, and cognitive scientists. (shrink)

How seriously should we take the idea that the mind employs mental files? Goodman and Gray (2022) argue that mental filing – a thinker rationally treating her cognitive states as being about the same thing – can be explained without files. Instead, they argue that the standard commitments of mental file theory, as represented by Recanati’s indexical model, are better seen in terms of a relational representational feature of object representations, which in turn is based on the (...) epistemic links a thinker bears to objects. This paper argues that this revision is misguided. Neither the representational property nor any basic role for epistemic links are needed for an adequate explanatory theory that makes use of the image of a mental filing system. A better alternative to the indexical model does posit files, albeit as causal-functional entities. This makes additional representational features redundant, and shows that epistemic links play a secondary role. (shrink)

This paper argues that applying a mental files framework for singular thought to thoughts about specific times could produce an account of tensed thought with significant advantages over competing theories. After describing the framework , I argue for the conceivability of treating particular times as res of singular thoughts , and the possibility that humans open ‘object files’ for them during perception . Then I discuss the possible make-up and function of a NOW indexical mental file . The (...) last section argues that, if our ‘now’ thoughts can be coherently analysed as thinking of a time under the NOW mental file, one would have a plausible explanation of the following issues: how tensed thought can refer to extended temporal intervals of various length; why reference to times is not destroyed by thought delays; and how a ‘now’ thought results in timely actions and, sometimes, relief.

The information processing capacity of the human mind is limited, as is evidenced by the so-called ‘‘attentional-blink’’ deficit: When two targets (T1 and T2) embedded in a rapid stream of events are presented in close temporal proximity, the second target is often not seen. This deficit is believed to result from competition between the two targets for limited attentional resources. Here we show, using performance in an attentional-blink task and scalp-recorded brain potentials, that meditation, or mental training, affects the (...) distribution of limited brain resources. Three months of intensive mental training resulted in a smaller attentional blink and reduced brain-resource allocation to the first target, as reflected by a smaller T1-elicited P3b, a brain-potential index of resource allocation. Furthermore, those individuals that showed the largest decrease in brain-resource allocation to T1 generally showed the greatest reduction in attentional-blink size. These observations provide novel support for the view that the ability to accurately identify T2 depends upon the efficient deployment of resources to T1. The results also demonstrate that mental training can result in increased control over the distribution of limited brain resources. Our study supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind. (shrink)

The very first edition of the book (New York: Columbia U. P., ) contained two paragraphs comparing Catholicism and Communism that were overlooked for the British and all subsequent editions. Russell regarded them as important, and Sir Stanley Unwin wrote him that they would be incorporated in the next printing.

I meet many people who think that the evils of Communism can be combated by Catholicism. This seems to me a dangerous error. What are the evils of Communism as it has developed? First, adherence to a rigid and static system of doctrine, of which part is doubtful and part demonstrably false. Second, persecution as a means of enforcing orthodoxy. Third, a belief that salvation is only to be found within the Church and that the True Faith must be spread throughout the world, by force if necessary. (These are the beliefs of Communists.) Fourth, that the priesthood, which alone has the right to interpret the Scriptures, has enormous power, physical east of the Iron Curtain and spiritual over the faithful in partibus. Fifth, that this power is used to secure an undue share of wealth for the priesthood at the expense of the rest of the population. Sixth, that bigotry, and the hostility that it engenders, is a potent source of war. Every one of these evils was exhibited by the Catholic Church when it had power and would probably be exhibited again if it recovered the position it had in the Middle Ages. It is therefore irrational to suppose that much would be gained if, in the defeat of Communism, Catholicism were enthroned in its place.

Properly understood, content internalism is the thesis that any difference between the representational contents of two individuals' mental states reduces to a difference in those individuals' intrinsic properties. Some of the strongest arguments against internalism turn on the possibility for two "doppelgangers" –- perfect physical and phenomenal duplicates -– to differ with respect to the contents of those of their mental states that they can express using terms such as "I," "here," and "now." In this paper, I grant (...) the stated possibility, but deny that it poses any threat to internalism. Despite their similarities, doppelgangers differ in some of their intrinsic properties, and it is to such intrinsic differences that differences of indexical content reduce. (shrink)

Background: Mentalizing, the mental capacity to understand oneself and others in terms of mental states, has been found to be reduced in several mental disorders. Some studies have suggested that eating disorders may also be associated with impairments in mentalizing. The aim of this work is to investigate the possible presence of mentalizing subtypes in a sample of patients with EDs.Method: A sample of patients with eating disorders completed a battery of measures assessing mentalization and related variables, (...) including the Reflective Functioning Questionnaire, the Difficulties in Emotion Regulation Strategies, the Interpersonal Reactivity Index. Clinicians rated patients in relation to imbalances in different dimensions of mentalization to prementalizing modes and attachment style by using the Mentalization Imbalances Scale, the Modes of Mentalization Scale, and the Adult Attachment Questionnaire. A latent profile analysis was conducted to test the possible presence of different subgroups. MANOVA was used to test the possible differences between the four mentalizing profiles in relation to emotion dysregulation, empathy, and adequate and impairments in mentalizing.Results: The latent profile analysis suggested the presence of four different profiles in relation to impairments in the dimensions of mentalization: affective/self/automatic imbalances, external imbalance, cognitive/self/automatic imbalances, and cognitive/other/automatic imbalances. Patients belonging to profile 1 are characterized by the prevalence of affective mentalization that overwhelms the capacity to reflect on mental states with an imbalance on the self-dimension; profile 2 patients are excessively focused on the external cues of mentalization; profile 3 patients are characterized by an over-involvement on the cognitive and self-facets of mentalization, with an impairment in adopting the other mind perspective; and profile 4 patients have similar impairments compared to profile 3 patients but with an excessive focus on others and deficits in self-reflection. These profiles were heterogeneous in terms of EDs represented in each group and presented significant differences on various variables such as attachment style, emotion dysregulation, empathy, interpersonal reactivity, and reflective function. This study represents, so far, the first work that confirms the presence of different mentalizing patterns in ED patients.Conclusions: ED patients can be classified in relation to impairments in different dimensions of mentalization above and beyond ED diagnosis.

Car driving is considered a very complex activity, consisting of different concomitant tasks and subtasks, thus it is crucial to understand the impact of different factors, such as road complexity, traffic, dashboard devices, and external events on the driver’s behavior and performance. For this reason, in particular situations the cognitive demand experienced by the driver could be very high, inducing an excessive experienced mental workload and consequently an increasing of error commission probability. In this regard, it has been demonstrated (...) that human error is the main cause of the 57 % of road accidents and a contributing factor in most of them. In this study, 20 young subjects were involved in a real driving experiment, performed under different traffic conditions (rush hour and not) and along different road types (main and secondary streets). Moreover, during the driving tasks different specific events, in particular a pedestrian crossing the road and a car entering the traffic flow just ahead of the experimental subject, were acted. A Workload Index based on the Electroencephalographic (EEG), i.e. brain activity, of the drivers has been employed to investigate the impact of the different factors on the driver’s workload. Eye-Tracking technology and subjective measures were also employed in order to have a comprehensive overview of the driver’s perceived workload and to investigate the different insights obtainable from the employed methodologies. The employment of such EEG-based Workload index confirmed the significant impact of both traffic and road types on the drivers’ behavior (increasing their workload), with the advantage of being under real settings. Also, it allowed to highlight the increased workload related to external events while driving, in particular with a significant effect during those situations when the traffic was low. Finally, the comparison between methodologies revealed the higher sensitivity of neurophysiological measures with respect to Eye-Tracking and subjective ones. In conclusion, such an EEG-based Workload index would allow to assess objectively the mental workload experienced by the driver, standing out as a powerful tool for research aimed to investigate drivers’ behavior and providing additional and complementary insights with respect to traditional methodologies employed within road safety research.

Francois Recanati presents the basic features of the *indexical model* of mental files, and defends it against several interrelated objections. According to this model, mental files refer to objects in a way that is analogous to that of indexicals in language: a file refers to an object in virtue of a contextual relation between them. For instance, perception and attention provide the basis for demonstrative files. Several objections, some of them from David Papineau, concern the possibility of (...) files to preserve and add information about objects across contexts. How is it possible to think about the same object when the subject no longer is in the original context? How is it possible to think of a perceived object as already known? Can this be done without an explicit identity judgment? Recanati answers these questions by invoking mental files of non-basic kinds and by describing the cognitive dynamics in which they take part. (shrink)

Mental files, in Recanati's framework, function as 'singular terms in the language of thought' ; they serve to think about objects in the world (and to store information about them). But they have a derived, metarepresentational function : they serve to represent how other subjects think about objects in the world. To account for the metarepresentational use of files, Recanati introduces the notion of an 'indexed file', i.e. a vicarious file that stands, in the subject's mind, for another subject's (...) file about an object. Using that notion, he argues, one can provide an analysis of attitude ascriptions and the conniving use of empty singular terms. (shrink)

BackgroundDepression is a serious mental disorder often accompanied by emotional and physiological disorders. Visceral fat index is the current standard method in the evaluation of visceral fat deposition. In this study, we explored the association between VAI and depression in the American population using NHANES data.MethodsA total of 2,577 patients were enrolled for this study. Data were collected through structured questionnaires. Subgroup analysis for the relationship between VAI and depression was evaluated using multivariate regression analysis after adjustment for potential (...) confounding factors.ResultsFor every 1 unit increase in VAI, the clinical depression increased by 14%. High VAI scores increased the highest risk of developing depression. Subgroup analysis demonstrated a strong and stable association between VAI and the development of depression.ConclusionOur study showed that depressive symptoms are associated with a high ratio of visceral adiposity index after controlling confounding factors.

Mental body-representations are highly plastic and can be modified after brief exposure to unexpected sensory feedback. While the role of vision, touch and proprioception in shaping body-representations has been highlighted by many studies, the auditory influences on mental body-representations remain poorly understood. Changes in body-representations by the manipulation of natural sounds produced when one's body impacts on surfaces have recently been evidenced. But will these changes also occur with non-naturalistic sounds, which provide no information about the impact produced (...) by or on the body? Drawing on the well-documented capacity of dynamic changes in pitch to elicit impressions of motion along the vertical plane and of changes in object size, we asked participants to pull on their right index fingertip with their left hand while they were presented with brief sounds of rising, falling or constant pitches, and in the absence of visual information of their hands. Results show an "auditory Pinocchio" effect, with participants feeling and estimating their finger to be longer after the rising pitch condition. These results provide the first evidence that sounds that are not indicative of veridical movement, such as non-naturalistic sounds, can induce a Pinocchio-like change in body-representation when arbitrarily paired with a bodily action.

According to the Maintainable Positive Mental Health Theory (MPMHT), the main pillars of positive mental health are global well-being, efficient coping that enables an individual to maintain positive conditions and functioning, savoring capacity, resilience, and dynamic self-regulation. This study presents the validation of a new five-scale mental health test (MHT), the MHT that operationalizes MPMHT. The methodology comprised two online cross-sectional studies using self-report questionnaires. Participants in Study I (n = 1,736; 448 males, 1,288 females; mean age (...) 51.3 years; SD = 11.6 years) filled in the MHT, the Flow, the Positive emotions, Engagement, Positive Relationship, Meaning, Accomplishment Questionnaire (PERMA-Profiler), and the Flourishing Scale. Participants in Study II (n = 1,083; 233 males, 847 females; mean age 33.9 years; SD = 12.2 years) filled in the MHT, the Shortened Aspiration Index, the short form of the Beck Depression Inventory, the WHO Well-Being Index, the Satisfaction with Life Scale, the Purpose in Life Test, and the Schema Questionnaire–Short Form. Exploratory factor analysis (EFA) identified a five-factor structure with 17 items in Study I that was confirmed with excellent fit measures in confirmatory factor analysis in Study II. Both studies indicated a high level of internal consistency (above 0.70). In each subscale, a minimum part of 44% did not overlap with the set of the other subscales. The content validity of the subscales was confirmed by 10 tests of mental health. We found a positive correlation of the self-regulation and resilience subscales with age, while women showed a higher level of savoring than men at all age levels. When Study I was replicated after 2 weeks and again after 11 months, excellent internal consistency and good test–retest correlation values of the MHT scales were found. The MHT can thus be considered a reliable and valid measurement tool for mental health. (shrink)

This paper describes a programmatic theory of a process in early vision called indexing. The theory hypothesizes that a small number of primitive indexes are available for individuating, tracking and providing direct access to salient visual objects. We discuss some empirical and theoretical arguments in favor of the proposed index as a resource-limited link between an internal visual representation and objects in the visual world. We argue that this link is needed to explain a large range of properties of vision, (...) including the ability to simultaneously track multiple moving objects, to select a subset of visual items to process, as well as such larger issues as how mental images get their apparent metrical properties and why the world appears stable despite constant retinal motion.

Psycholinguistic investigations of the way readers and speakers perceive gender have shown several biases associated with how gender is linguistically realized in language. Although such variations across languages offer interesting grounds for legitimate cross linguistic comparisons, pertinent characteristics of grammatical systems – especially in terms of their gender asymmetries – have to be clearly identified. In this paper, we present a language index for researchers interested in the effect of grammatical gender on the mental representations of women and men. (...) Our index is based on five main language groups (i.e., grammatical gender languages, languages with a combination of grammatical gender and natural gender, natural gender languages, genderless languages with few traces of grammatical gender and genderless languages) and three sets of specific features (morphology, masculine-male generics and asymmetries). Our index goes beyond existing ones in that it provides specific dimensions relevant to those interested in psychological and sociological impacts of language on the way we perceive women and men. We also offer a critical discussion of any endeavor to classify languages according to grammatical gender. (shrink)

Human errors are widely considered among the major causes of road accidents. Furthermore, it is estimated that more than 90% of vehicle crashes causing fatal and permanent injuries are directly related to mental tiredness, fatigue, and drowsiness of the drivers. In particular, driving drowsiness is recognized as a crucial aspect in the context of road safety, since drowsy drivers can suddenly lose control of the car. Moreover, the driving drowsiness episodes mostly appear suddenly without any prior behavioral evidence. The (...) present study aimed at characterizing the onset of drowsiness in car drivers by means of a multimodal neurophysiological approach to develop a synthetic electroencephalographic -based index, able to detect drowsy events. The study involved 19 participants in a simulated scenario structured in a sequence of driving tasks under different situations and traffic conditions. The experimental conditions were designed to induce prominent mental drowsiness in the final part. The EEG-based index, so-called “MDrow index”, was developed and validated to detect the driving drowsiness of the participants. The MDrow index was derived from the Global Field Power calculated in the Alpha EEG frequency band over the parietal brain sites. The results demonstrated the reliability of the proposed MDrow index in detecting the driving drowsiness experienced by the participants, resulting also more sensitive and timely sensible with respect to more conventional autonomic parameters, such as the EyeBlinks Rate and the Heart Rate Variability, and to subjective measurements.

Internalism about mental content is the view that microphysical duplicates must be mental duplicates as well. This dissertation develops and defends the idea that only a strong version of internalism is compatible with our commonsense commitment to mental causation. ;Chapter one defends a novel necessary condition on a property's being causally efficacious---viz., that any property F that is efficacious with respect to event E cannot be instantiated in virtue of any property G that is itself ceteris paribus (...) sufficient for E---and shows that that necessary condition vindicates the idea that externalism is incompatible with our commonsense commitment to mental causation. ;The internalist's core intuition is that only intrinsic properties can be causally efficacious. Chapter two defends that intuition from the common externalist response that extrinsic properties abound. ;A popular "Middle Way" between externalism and internalism holds that although ordinary, "folk-psychological" contents of prepositional attitudes are extrinsic, there exists some other non-folk-psychological kind of content that is intrinsic. Chapter three argues that Jerry Fodor's influential argument for the Middle Way is incoherent. ;Chapter four identifies a weak but popular grade of internalism, endorsed by John Searle among others, and argues that it is untenable. ;The preceding defense of internalism can be believed only if there is something wrong with the canonical arguments for externalism developed by Hillary Putnam, Tyler Burge, and Saul Kripke. My postscript says what I think is wrong with the canonical externalist arguments: they assume the nonexistence of propositions that are truth-evaluable only relative to particular persons, places, or times; while I argue that our commonsense commitment to mental causation requires at least some such "indexical propositions".

The aim of this article is to adapt Peirce’s semiotics to the study of media and arts. While some Peircean notions are criticized and rejected, constructive ways of understanding Peirce’s ideas are suggested, and a number of new notions, which are intended to highlight crucial aspects of semiosis, are then introduced. All these ideas and notions are systematically related to one another within the frames of a consistent terminology. The article starts with an investigation of Peirce’s three sign constituents and (...) their interrelations: the representamen, the object, and the interpretant. A new approach to the interrelations of these three sign constituents is then suggested and manifested in a distinction between representation and neopresentation. This is followed by a critical discussion of Peirce’s three types of representation—iconicity, indexicality, and symbolicity—and their interrelations, which sets the stage for a presentation of what is referred to as the material and mental representation model. This model aims to illuminate the problematic relation between material and mental facets of signification triggered by media and art products, and other material things and phenomena. (shrink)

The present trend towards an atheoretical statistical method of psychiatric classification has prompted many psychiatrists to conceive of "mental disorder", or for that matter any other psychopathological designation, as an indexical cluster of properties and events more than a distinct psychological impairment. By employing different combinations of inclusion and exclusion criteria, the current American Psychiatric Association's scheme (called DSM-III) hopes to avoid the over-selectivity of more metaphysical systems and thereby provide the clinician with a flexible means of dealing with (...) a wide diversity of cases. In the hope of redirecting future inquiry, the paper will argue: (1) that this recent trend might appear to be clinically beneficial, but in point of fact it is riddled by unsound theoretical conclusions which leave the field without a deeply reaching base for understanding and treating mental disorder, and (2) that, a fortiori, "mental disorder" is best conceived as not a cluster of properties and events, nor a metaphorical reaction to a breakdown in social interpersonal relations, but as a deeply laid condition characterized by the absence of an imaginally integrated system.

This paper is devoted to an examination of the topic of cognitive dynamics as introduced by David Kaplan in his essay ‘Demonstratives’. I discuss two approaches to cognitive dynamics: the directly referential approach, which I take as best represented in Kaplan’s views, and the neo-Fregean approach, which I take as best represented in Gareth Evans’s views. The upshot of my discussion is twofold. On the one hand, I argue that both Kaplan’s account and Evans’s account are on the whole defective (...) - even though there are features of each of those views which seem to be along the right lines. On the other hand, I claim that a broadly Fregean account is still to be preferred since by positing semantically efficacious modes of presentation it is clearly better equipped to deal with thephenomena in the area. In particular, I argue that the notion of a memory-based mode of presentation of an object turns out to be indispensable for the purpose of accounting for the persistence of intentional mental states over time.

After thirty years of the current “imagery debate,” it appears far from resolved, even though there seems to be a growing acceptance that a cortical display cannot be identified directly with the experienced mental image, nor can it account for the experimental findings on imagery, at least not without additional ad hoc assumptions. The commentaries on the target article range from the annoyed to the supportive, with a surprising number of the latter. In this response I attempt to correct (...) some misreadings of the target article and discuss some of the ideas and evidence introduced by the commentators – much of which I found helpful, even though they do not alter my basic thesis. I also further develop the idea that the spatial character of images may come from the way they are connected to our immediate or immediately-recalled environment (by attention or by visual indexes) and towards which we may orient while we are imaging, thus leaving the alleged spatial properties of images outside the head and freeing image-representations from having to be displayed on any surface.

This paper is devoted to an examination of issues concerning the persistence and linguistic re-expression of indexical singular belief. I discuss two approaches to the topic: the directly referential approach, which I take as best represented in Kaplan's views, and the neo-Fregean approach, which I take as best represented in Gareth Evans's views. The upshot of my discussion is twofold. On the one hand, I argue that both Kaplan's account and Evans's account are on the whole defective. On the other, (...) I claim that a broadly Fregean account is still to be preferred, since by positing semantically efficacious modes of presentation it is clearly better equipped to deal with the phenomena in the area. In particular, I argue that the notion of a memory-based mode of presentation of an object (a spatio-temporal particular, a region in space, a period of time, etc.), as introduced by Christopher Peacocke, turns out to be indispensable to account for the persistence and re-expression of intentional mental states over time.

This article looks at Husserlian ideas as an analytical tool to explain the cognitive aspects of experiences that range between knowledge acts in inferences and Mulligan’s contemporary perspective of meaning formation, through reflections of relations. The essay also takes into consideration the views of Levinas and Hintikka, for whom experiences form the foundations of intuitive capacity. These perspectives are essential concerning epistemic evidence to self (I/me-ness): mental objects and spatiotemporal relations are the structural notions of episteme on their own; (...) their dynamics were tightly coordinated at an intentional process to strengthen episteme; this coordination appeared to be a state change caused in epistemic evidence.

Nonsymbolic comparison tasks are commonly used to index the acuity of an individual's Approximate Number System (ANS), a cognitive mechanism believed to be involved in the development of number skills. Here we asked whether the time that an individual spends observing numerical stimuli influences the precision of the resultant ANS representations. Contrary to standard computational models of the ANS, we found that the longer the stimulus was displayed, the more precise was the resultant representation. We propose an adaptation of the (...) standard model, and suggest that this finding has significant methodological implications for numerical cognition research. (shrink)

BackgroundResearch on prevalence of cognitive frailty phenotypes in community-dwelling older adults in different countries is important to estimate their prevalence and to determine the influence of cognitive reserve and mental health in order to prevent frailty. The aims of this study were to estimate the prevalence of reversible and potentially reversible cognitive frailty in a Portuguese sample of old adults and explore the associations between these phenotypes and demographic, comorbidity, social support, cognitive reserve and mental health factors.MethodsWe assessed (...) frailty in 250 community-dwelling older adults aged 60 years or over without dementia, neurological or psychiatric disorders. Subjective cognitive decline and Mild cognitive impairment were diagnosed according to standard criteria. The questionnaires Charlson Index, Medical Outcomes Study Social Support, Cognitive Reserve Index and General Health were used for assessing comorbidity, social support, cognitive reserve and mental health, respectively.ResultsPrevalence of R-CF was 14%, and that of PR-CF, 15.2%. Cognitive frailty profiles differed significantly in relation to education, comorbidity, mental health, and cognitive reserve, but not in age or sex. Multivariate logistic regression showed that age, sex, comorbidity, social support, mental health, and cognitive reserve together predicted R-CF and PR-CF with significant OR for mental health and cognitive reserve.DiscussionCognitive reserve and mental health are important factors predicting R-CF and PR-CF. We recommend assessing these factors for early detection of cognitive frailty and promoting psychological well-being and lifestyles that increase cognitive reserve in adults. (shrink)
