One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

The senses, or sensory modalities, constitute the different ways we have of perceiving the world, such as seeing, hearing , touching, tasting, and smelling. But what makes the senses different? How many senses are there? How many could there be? Wha t interaction takes place between the senses? This introduction is a guide to thinking about these questions.

The dual role of olfaction in both smelling and tasting, i.e. flavour perception, makes it an important test case for philosophical theories of sensory individuation. Indeed, the psychologist Paul Rozin claimed that olfaction is a “dual sense”, leading some scientists and philosophers to propose that we have not one, but two senses of smell: orthonasal and retronasal olfaction. In this paper I consider how best to understand Rozin’s claim, and upon what grounds one might judge there to be one (...) or two distinct olfactory modalities. I conclude that while Rozin may be right that humans have dual occurrences of an olfactory ‘sense’, the concept of a sense-modality, and hence the ‘sense’ of smell, is ambiguous between two different notions: a physiological sensory channel and an experiential modality, along the lines suggested by J. J. Gibson. Furthermore, recognising that these are complementary rather than competing conceptions of a sense-modality enables the formulation of a powerful ‘dual-concept’ framework for posing and addressing questions concerning the complex architecture of human multisensory experience.

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (shrink)

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

How do we individuate the senses, what exactly do we do when we do so, and why does it matter? In the following article, I propose a general answer to these related questions based on Franz Brentano's views on the senses. After a short survey of various answers offered in the recent literature on the senses, I distinguish between two major ways of answering this question, causally and descriptively, arguing that only answers giving priority to description and (...) to the classification involved in it are on the right track for a general answer to the related questions. In the second part of the article, I argue that Brentano's descriptive psychology is an attractive candidate for such an answer. His descriptive psychology provides a plausible account of the classification involved in description, in particular regarding the classification of sensory qualities. I close the article by briefly explaining how Brentano spells out the priority of descriptive answers over causal ones. (shrink)

The sense of agency has received much attention in the context of individual action but not in the context of joint action. We investigated how the sense of agency developed during individual and dyadic performance while people learned a haptic coordination task. The sense of agency increased with better performance in all groups. Individuals and dyads showed a differential sense of agency after initial task learning, with dyads showing a minimal increase. The sense of agency depended on the context in (...) which the task was first learnt, as transfer from joint to individual performance resulted in an illusory boost in the sense of agency. Whereas the quality of performance related to the sense of agency, the generated forces to achieve the task did not. Our findings are consistent with a predictive model account at the perceptual level, such that the sense of agency relies most strongly on sharable perceptual information. (shrink)

Many individuals with developmental language disorder (DLD) and individuals who are deaf or hard of hearing (D/HH) have social–emotional problems, such as social difficulties, and show signs of aggression, depression, and anxiety. These problems can be partly associated with their executive functions (EFs) and theory of mind (ToM). The difficulties of both groups in EF and ToM may in turn be related to self-directed speech (i.e., overt or covert speech that is directed at the self). Self-directed speech is thought to (...) allow for the construction of non-sensory representations (i.e., representations that do not coincide with direct observation). Such non-sensory representations allow individuals to overcome the limits set upon them by the senses. This ability is constrained by the development of word meaning structure (i.e., the way words are understood). We argue that the greater ability to construct non-sensory representations may result in more enhanced forms of EF and ToM. We conclude that difficulties in EF, ToM, and social–emotional functioning in those with hearing and language problems may be accounted for in terms of word meaning impairments. We propose that word meaning structure and self-directed speech should be considered in assigning EF and ToM treatments to individuals with DLD and those who are D/HH. (shrink)

How many senses do humans possess? Five external senses, as most cultures have it—sight, hearing, touch, smell, and taste? Should proprioception, kinaesthesia, thirst, and pain be included, under the rubric bodily sense? What about the perception of time and the sense of number? Such questions reduce to two. 1. How do we distinguish a sense from other sorts of information-receiving faculties? 2. By what principle do we distinguish the senses? Aristotle discussed these questions in the De Anima. (...) H. P. Grice revived them in 1967. More recently, they have taken on fresh interest as a result of a collection of essays edited by Fiona Macpherson. This entry reviews some approaches to these questions and advances some new ideas for the reader’s consideration. It proposes that the senses constitute an integrated learning system, membership in which answers question 1. It also proposes that the modalities can be distinguished from one another in two ways, by the means of information pick-up and by the kinds of activity that a perceiver undertakes to make use of them.

After first noting that I seek to broaden the definition of science fiction to a little more loosely defined speculative fiction, this essay explores four different ways in which fiction can work together with both the sciences and the philosophy of perception. This cooperation is needed because there is much about the sensory worlds of humans and non-human animals of which we continue to be ignorant. First, speculative fiction can be a source of hypotheses about the nature of the (...) class='Hi'>senses. Second, it can help us understand the inner worlds of beings different from us. Third, speculative fiction often pushes us to investigate the ethical and social dimensions of sensory difference. Finally, speculative fiction can play an important role in reconciling our scientific understanding of the senses with a more commonsense understanding of same. (shrink)

While it is highly controversial whether Frege's criterion of sameness and difference for sense is true, it is relatively uncontroversial that that principle is inconsistent with Millian–Russellian views of content. I argue that this should not be uncontroversial. The reason is that it is surprisingly difficult to come up with an interpretation of Frege's criterion which implies anything substantial about the sameness or difference of content of anything.

I argue that we should reject the sparse view that there are or could be only a small number of rather distinct senses. When one appreciates this then one can see that there is no need to choose between the standard criteria that have been proposed as ways of individuating the senses—representation, phenomenal character, proximal stimulus and sense organ—or any other criteria that one may deem important. Rather, one can use these criteria in conjunction to form a (...) fine-grained taxonomy of the senses. We can think of these criteria as defining a multidimensional space within which we can locate each of the senses that we are familiar with and which also defines the space of possible senses there could be.

Much work on the sense of agency has focused either on abnormal cases, such as delusions of control, or on simple action tasks in the laboratory. Few studies address the nature of the sense of agency in complex natural settings, or the effect of skill on the sense of agency. Working from 2 case studies of mountain bike riding, we argue that the sense of agency in high-skill individuals incorporates awareness of multiple causal influences on action outcomes. This allows fine-grained (...) differentiation of the contributions of self and external factors to action outcomes. We further argue that the sense of agency incorporates prospective awareness of actions that are possible in a situation and awareness of the limits of control. These forms of sense of agency enable highly flexible, context-sensitive strategic control, and are likely to contribute to high interindividual variability in responses to complex tasks. (shrink)

Philosophers and scientists have studied sensory perception and, in particular, vision for many years. Increasingly, however, they have become interested in the nonvisual senses in greater detail and the problem of individuating the senses in a more general way. The Aristotelian view is that there are only five external senses—smell, taste, hearing, touch, and vision. This has, by many counts, been extended to include internal senses, such as balance, proprioception, and kinesthesis; pain; and potentially other (...) human and nonhuman senses. This “multisensory turn” has been driven partly by developments in contemporary psychology and neuroscience, which have revealed a host of complex interrelations and interactions between sensory modalities previously thought to be distinct. Contrasts between modalities and other crossmodal phenomena, including multisensory integration, synesthesia, and sensory substitution, have also begun to receive more attention in a burgeoning scientific and philosophical literature on multisensory perception and other crossmodal effects. This article focuses on recent empirically informed contributions to the philosophy of perception, as well as key scientific works that provide important background information and insights into the nature of the senses and sensory perception. Indeed, one of the lessons of the multisensory turn, and of contemporary philosophy of mind more generally, is that philosophers ignore this body of empirical research at their peril because many human and animal senses turn out to be richer and more complex than philosophers and scientists had previously imagined, making this a fruitful area for interdisciplinary interaction and research.

We perceive in many ways. But several dubious presuppositions about the senses mask this diversity of perception. Philosophers, scientists, and engineers alike too often presuppose that the senses (vision, audition, etc.) are independent sources of information, perception being a sum of these independent contributions. We too often presuppose that we can generalize from vision to other senses. We too often presuppose that vision itself is best understood as a passive receptacle for an image thrown by a lens. (...) In this essay we illustrate how reflection on results from the cognitive sciences undermine these (and many other) traditional presuppositions. Our illustration situates the remaining essays in the volume, Perception and its Modalities, which further extend the case against various traditional presuppositions, and offer alternatives ways to understand the senses and their role in perception. While many of the essays in this volume represent competing views and draw on different fields, from conceptual analysis to engineering, most contributors believe that to understand perception properly, we need to treat as foundational the idea that the senses work together. From that agreement, new paradigms for theorizing about perception begin to emerge. (shrink)

The social contract approach to the study if institutions aims at providing a solution to the problem of compliance with rational agreements in situations characterized by a conflict between individual rationality and social optimality. After a short discussion of some attempts to deal with this problem from a rational choice perspective, we focus on John Rawls's idea of 'sense of justice' and its application to the explanation of the stability of a well-ordered society. We show how the relevant features of (...) Rawls's theory can be captured by a behavioral game theory model of beliefs dependent dispositions to comply, and we present the results of two experimental studies that provide support to the theory.

According to the reading offered here, Descartes' use of the meditative mode of writing was not a mere rhetorical device to win an audience accustomed to the spiritual retreat. His choice of the literary form of the spiritual exercise was consonant with, if not determined by, his theory of the mind and of the basis of human knowledge. Since Descartes' conception of knowledge implied the priority of the intellect over the senses, and indeed the priority of an intellect operating (...) independently of the senses, and since, in Descartes' view, the untutored individual was likely to be nearly wholly immersed in the senses, a procedure was needed for freeing the intellect from sensory domination so that the truth might be seen. Hence, the cognitive exercises of the Meditations, modeled not on the sense- and imagination-based exercises of Ignatius of Loyola, but on the Augustinian procedure of turning away from the senses and imagination to perceive the unpicturable with the fleshless eye of the mind. In accordance with this reading, the function of Descartes' skeptical arguments is not to introduce skepticism so that it can be defeated but to aid the meditator in withdrawing the mind from the senses in order to attend to truths of the pure intellect. These truths then offer the basis for a new natural philosophy, including a new theory of the senses. (shrink)

Many philosophers nowadays believe Frege was right about belief, but wrong about language: The contents of beliefs need to be individuated more finely than in terms of Russellian propositions, but the contents of utterances do not. I argue that this 'hybrid view' cannot offer no reasonable account of how communication transfers knowledge from one speaker to another and that, to do so, we must insist that understanding depends upon more than just getting the references of terms right.

The sense of supernatural agency constitutes a defining characteristic of the religious sphere of life. But what accounts for the continued cross-cultural recurrence of this psychological phenomenon over the course of human history? This paper reviews evidence indicating that the source of panhuman or universal cognitive patterns of thought and behaviour such as this lies in the common characteristics of the evolved human mind. Further, that the sense of the supernatural is constituted by a unique combination of commonly recurring cognitive (...) processes that together give rise to a panhuman conviction in the reality of supernatural agencies able and willing to assist each individual in situations deemed beyond the capacities of that individual. These cognitive processes are driven most acutely by existential anxiety in response to extrinsic physical, economic and social pressures indicating that religiosity is best understood as a social-psychological phenomenon.

This paper analyzes the concept of truth in terms of an account of Fregean sense as cognitive value. The account highlights the importance of understanding-based knowledge of co-reference for the individuation of senses. Explicit truth attributions, like ‘that I smell the scent of violets is true’ involve an inter-level version of understanding-based knowledge of co-reference in the that-clause concepts of thoughts that they employ: one cannot understand the that-clause concept of the thought in the truth attribution without understanding the (...) thought the that-clause concept is a concept of. This is not a redundancy that eliminates or deflates cognitive value, but an exploitation, by the concept of truth, of the inter-level version of understanding-based knowledge of co-reference in critical reflective thinking. The cognitive value of the concept of truth is to combine semantically with explicit ways of thinking of thoughts to make critical reflective thinking possible. This account of the cognitive value of the concept of truth assigns cognitive value not by construing the concept of truth as a way of thinking about some thing, but by articulating its broader cognitive role.

Published in 1896, The Sense of Beauty secured Santayana's reputation as a philosopher and continued to outsell all of his books until the publication of his one novel, The Last Puritan. Even today, it is one of the most widely read volumes in all of Santayana's vast philosophical work. It is a large irony that Santayana disowned The Sense of Beauty from the beginning, and wrote it only to keep his job teaching at Harvard. In 1950 he met with the (...) philosopher Arthur Danto in the Roman convent clinic where he passed his final years, and reminisced that "they let me know through the ladies that I had better publish a book." "On what?" "On art, of course. So I wrote this wretched potboiler" In fact, the book was based on a well known course on the theory and history of aesthetics that Santayana gave at Harvard College from 1892 to 1895. Santayana approaches the study of aesthetics through a naturalistic basis in human psychology: "Beauty is pleasure regarded as the quality of a thing." As such, he observes, beauty does not reside in the object but in the individual's sense of beauty. This in no way reduces the importance or the value of art or aesthetic experience. For Santayana, beauty is not relegated to museum art or to some limited arena of aesthetic experience; rather, beauty informs the whole of human existence. Herman J.

How ought we differentiate the senses? What, say, distinguishes vision from audition? The question comes in two versions. First, there is the traditional problem of individuating the senses in humans. Second, there is also an important question about what sensory modalities we ought to attribute to non-human animals, a version of the question that has been virtually ignored by philosophers. Modality ought to be construed as an “avenue into” an organism for information external to the central nervous (...) system. Six proposed criteria found in the philosophical literature concerning the senses are reviewed. Initially, four criteria—physics, neurobiology, behavior, and evolutionary or developmental dedication—are shown to be individually necessary and jointly sufficient. Next, two criteria—Aristotle's proper objects of sensation criterion and Grice's sensation or qualia criterion—are considered and rejected. One overarching goal here is to show that there is interesting contemporary work left to be done on this ancient philosophical question. (shrink)

In recent years, there has been an increasing interest in the role of collective memory in ethno-national projects. In addition, there has been an expansion of research utilising memory work and auto/biographical methods, which have been particularly effective in the writing of feminists of colour. The paper is prompted by a return to Avtar Brah's ‘The Scent of Memory’ that it uses as a starting point to explore the relationships between competing accounts of ‘private’ memories of racialisation that come from (...) mixed-race siblings growing up in a mainly white town. Drawing on interviews, the paper uses familial narratives and their individual telling, to show how sense is made of divergent experiences and memories of childhood and teenage in 1960s and 1970s Britain. The paper shows how narrative accounts are often negotiated through multiple senses, revealing them as both imagined and recalled, contested and negotiated. The paper considers the strengths and limitations of narrative analysis in understanding the relationship between individual and collective memories at both national and familial levels. It argues that the ways in which the social and personal memories are connected in the processes of subjectivation are unstable and opaque, and can only ever be partially known through the process of narrativisation.

Seeing, hearing and touching are phenomenally different, even if we are detecting the same spatial properties with each sense. This presents a prima facie problem for intentionalism, the theory that phenomenal character supervenes on representational content. The paper reviews some attempts to resolve this problem, and then looks in detail at Peter Carruthers' recent proposal that the senses can be individuated by the way in which they represent spatial properties and incorporate time. This proposal is shown to be ineffective (...) in distinguishing auditory from either visual or tactual perception, and substantial classes of visual and tactual perceptions are found that the posited spatial and temporal features fail to individuate.

The paper examines the dialectics of the sense of life and death. In the analysis three mutually dependent points of view are applied: existential , moral and psychological ones. The author focuses on the individual confronting the impending unescapa- bili_ty of death in an existential condition of a fatal desease. On this practical level it is concerned with the knowing and understanding the proces of dying and its inner dimension as well as its external determination.

Definitions of the concept of mild cognitive impairment (MCI) and suggested therapies are controversial. There are no widely acknowledged therapies and the ethical implications and methodologic issues around identifying and defining people with MCI are important concerns. The psychosocial implications for the person being labeled as having MCI have not been widely explored. This paper addresses these issues and presents data from two contrasting case studies. Key analytical themes identified in the qualitative analysis include different views about the causes of (...) dementia ("normal aging" versus disease); fear and anxiety about dementia; how such factors influence presentation to health professionals; and the effect of a label of cognitive impairment on quality of life. Our conclusion is that the usefulness and justification for early identification of cognitive impairment in a situation that has not yet been recognized by those involved should be questioned.

Schizophrenia is a disturbance of the self, of which the attribution of agency is a major component. In this article, we review current theories of the Sense of Agency, their relevance to schizophrenia, and propose a novel framework for future research. We explore some of the models of agency, in which both bottom-up and top-down processes are implicated in the genesis of agency. We further this line of inquiry by suggesting that ongoing neurological activity (the brain’s resting state) in self-referential (...) regions of the brain can provide a deeper level of influence beyond what the current models capture. Based on neuroimaging studies, we suggest that aberrant activity in regions such as the default mode network of individuals with schizophrenia can lead to a misattribution of internally/externally generated stimuli. This can result in symptoms such as thought insertion and delusions of control. Consequently, neuroimaging can contribute to a more comprehensive conceptualization and measurement of agency and potential treatment implications. (shrink)

It has been claimed that a sense of us is presupposed for shared intentions to be possible. Searle introduced this notion together with the notion of the sense of the other. in joint action. It argues that the sense of the other is a necessary condition for a sense of us. Whereas thisarticle distinguishes between the “sense of the other” and the “sense of us” and elaborates on their role the sense of the other is immediate and automatic, the sense (...) of us can (but need not) arise between people and can (a) develop over time, (b) depend on the situation, and (c) involves several sufficient but not necessary processes. The article relies on research on core knowledge to better understand the sense of the other. It elaborates the sense of us using insights from cognitive science and social psychology. The article shows that the sense of the other and the sense of us can contribute to our understanding of the perception of possibilities for joint action and how individuals can come to experience actions and intentions as shared, even if the participants lack common knowledge. This leads to the conclusion that people are ordinarily socially oriented rather than individually. (shrink)

How should we characterize the nature of perceptual experience? Some theorists claim that colour experiences, to take an example of perceptual experiences, have both intentional properties and properties called 'colour qualia', namely, mental qualitative properties which are what it is like to be conscious of colour. Since proponents of colour qualia hold that these mental properties cannot be explained in terms of causal relations, this position is in opposition to a functionalist characterization of colour experience.

Günther’s book demonstrates that most objections to moral and legal principles are directed not against the validity of principles but against the manner of their application. If one distinguishes between the justification of a principle and its appropriate application, then the claim that the application of the principle in each individual case follows automatically from its universal justification proves to be a misunderstanding. Günther develops this distinction with the help of Habermas’s discourse theory of morality. He then employs it to (...) extend Kohlberg’s theory of moral development and to defend this against Gilligan’s critique. In the third and fourth parts of the book, Günther shows—in debate with Hare, Dworkin, and others—how argumentation on the appropriate application of norms and principles in morality and law is possible.

It is widely assumed that the art media can be individuated with reference to the sense modalities. Different art media are perceived by means of different sense modalities, and this tells us what properties of each medium are aesthetically relevant. The case of pictures appears to fit this principle well, for pictures are deemed purely and paradigmatically visual representations. However, recent psychological studies show that congenitally and early blind people have the ability to interpret and make raised‐line drawings through touch. (...) This shows that pictures are not essentially visual representations. The view that pictures are essentially visual follows from influential views of the nature of depiction and of the nature of vision that are mistaken. By rooting out the mistake, we learn something about pictures, something about vision, and something about the doctrine that art media are individuated by the sense modalities. (shrink)

Power differentials are a ubiquitous feature of social interactions and power has been conceptualised as an interpersonal construct. Here we show that priming power changes the sense of agency, indexed by intentional binding. Specifically, participants wrote about episodes in which they had power over others, or in which others had power over them. After priming, participants completed an interval estimation task in which they judged the interval between a voluntary action and a visual effect. After low-power priming, participants judged intervals (...) to be significantly longer than judgments after high-power or no priming. Thus, intentional binding was significantly changed by low-power, suggesting that power reduces the sense of agency for action outcomes. Our results demonstrate a clear intrapersonal effect of power. We suggest that intentional binding could be employed to assess agency in individuals suffering from anxiety and depression, both of which are characterised by reduced feelings of personal control.

Orthodox neurocognitive accounts of the bodily sense of agency suggest that the experience of agency arises when action-effects are anticipated accurately. In this paper, I argue that while successful anticipation is crucial for the sense of agency, the role of unsuccessful prediction has been neglected, and that inefficacy and uncertainty are no less central to the sense of agency. I will argue that this is reflected in the phenomenology of agency, which can be characterized both as the experience of efficacy (...) and effort. Specifically, the “sense of efficacy” refers to the perceptual experience of an action unfolding as anticipated. The “sense of effort”, in contrast, arises when an action has an uncertain trajectory, feels difficult, and demands the exertion of control. In this case, actions do not unfold as anticipated and require continuing adaptation if they are to be efficacious. I propose that, taken individually, the experience of efficacy and effort are insufficient for the sense of agency and that these experiences can even disrupt the sense of agency when they occur in isolation from each other. I further argue that a fully-fledged sense of agency depends on the temporally extensive process of prediction error-cancelation. This way, a comparator account can accommodate both the role of accurate prediction and prediction error and thus efficacy and effort. (shrink)

Individuals differ greatly in their ability to learn and navigate through environments. One potential source of this variation is “directional sense” or the ability to identify, maintain, and compare allocentric headings. Allocentric headings are facing directions that are fixed to the external environment, such as cardinal directions. Measures of the ability to identify and compare allocentric headings, using photographs of familiar environments, have shown significant individual and strategy differences; however, the neural basis of these differences is unclear. Forty-five college students, (...) who were highly familiar with a campus environment and ranged in self-reported sense-of-direction, underwent fMRI scans while they completed the Relative Heading task, in which they had to indicate the direction of a series of photographs of recognizable campus buildings (i.e., “target headings”) with respect to initial “orienting headings”. Large individual differences were found in accuracy and correct decision latencies, with gender, self-reported sense-of-direction, and familiarity with campus buildings all predicting task performance. Using linear mixed models, the directional relationships between headings and the experiment location also impacted performance. Structural scans revealed that lateral orbitofrontal and superior parietal volume were related to task accuracy and decision latency, respectively. Bilateral hippocampus and right presubiculum volume were related to self-reported sense-of-direction. Meanwhile, functional results revealed clusters within the superior parietal lobule, supramarginal gyrus, superior frontal gyrus, lateral orbitofrontal cortex, and caudate among others in which the intensity of activation matched the linear magnitude of the difference between the orienting and target headings. While the retrosplenial cortex and hippocampus have previously been implicated in the coding of allocentric headings, this work revealed that comparing those headings additionally involved frontal and parietal regions. These results provide insights into the neural bases of the variation within human orientation abilities, and ultimately, human navigation. (shrink)

This paper investigates the nature of emotional experience in relation to the senses, and it defends the thesis that emotional experience is partly non-sensory. In §1 I introduce my reader to the debate. I reconstruct a position I call ‘restrictivism’ and motivate it as part of a reductive approach to mind’s place in nature. Drawing on intuitive but insightful remarks on the nature of sensation from Plato, I map out the conditions under which the restrictivist thesis is both substantive (...) and plausible. I then present two arguments against it. The first argument, which I lay out in §2, draws on recent empirical results in emotion research to show that restrictivism cannot be reconciled with the possibility of knowledge of one’s own emotional state by acquaintance. The second argument, which I present in §3, individuates a claim on which most contemporary theories of emotional valence converge and uses it to demonstrate that restrictivism has a false implication: it must deny that valence is experientially felt.

In this target article we question the assumption that perception is divided into separate domains of vision, hearing, touch, taste, and smell. We review implications of this assumption for theories of perception and for our understanding of ambient energy arrays (e.g., the optic and acoustic arrays) that are available to perceptual systems. We analyze three hypotheses about relations between ambient arrays and physical reality: (1) that there is an ambiguous relation between ambient energy arrays and physical reality, (2) that there (...) is a unique relation between individual energy arrays and physical reality, and (3) that there is a redundant but unambiguous relation, within or across arrays, between energy arrays and physical reality. This is followed by a review of the physics of motion, focusing on the existence and status of referents for physical motion. Our review indicates that it is not possible, in principle, for there to be a unique relation between physical motion and the structure of individual energy arrays. We argue that physical motion relative to different referents is specified only in the global array, which consists of higher-order relations across different forms of energy. The existence of specificity in the global array is consistent with the idea of direct perception, and so poses a challenge to traditional, inference-based theories of perception and cognition. However, it also presents a challenge to much of the ecological approach to perception and action, which has accepted the assumption of separate senses. (shrink)

In this paper, I defend a new theory of the nature and individuation of perceptual capacities. I argue that we need a theory of perceptual capacities to explain modal facts about what sorts of perceptual phenomenal states one can be in. I defend my view by arguing for three adequacy constraints on a theory of perceptual capacities: perceptual capacities must be individuated at least partly in terms of their place in a hierarchy of capacities, where these capacities include the (...) class='Hi'>senses themselves; an adequate account of perceptual capacities must be sensitive to empirical considerations; and an adequate account should accommodate the nature of the capacity to perceive. I arrive at these constraints by considering how Schellenberg’s view fails, before defending and developing my alternative in line with the constraints. I defend a view on which there are few, coarse-grained perceptual capacities which can fulfil complex explanatory roles because they are evaluatively gradable on many axes. Finally, on my view, perceptual capacities bear a particularly close relation to the sensory modalities themselves. (shrink)

Most of us, at one time or another, will have been struck by a thought that we might wish to express in the following words: ‘I could have been born in a different time and place, my position in life and all my personal characteristics could have been completely different from what they are; how amazing then that it should have fallen to my lot to live my life, the only life I shall ever live, as this particular individual rather (...) than any other.’ This thought need not derive from a sense that there is anything unusual about one's life; what it expresses, rather, may be the sense that there is something gratuitous or contingent about one's being any particular individual at all. This sense of contingency might be connected with a feeling of gratitude, perhaps of responsibility towards others less fortunate in life; or it might be bound up with envy, or pride, or self-pity, etc. (shrink)

What does an understanding of the first person pronoun “I” contribute to the understanding of a sentence involving “I”? This paper emphasizes that the first person pronoun is typically used as a tool of communication. We need to think not just about what it is to use the first person pronoun with understanding, but also what it is to understand someone else’s use of the first person pronoun. A plausible principle governing linguistic understanding via the conditions of adequacy upon reporting (...) speech entails what I call the symmetry constraint, which is that an account of the sense of “I” must leave open the possibility of sentences involving “I” saying the same thing as sentences involving “you”. One immediate consequence of the symmetry constraint is that we need to make a distinction between token-sense and type-sense, discussed in sections 1 and 2. A number of authors, most prominently Gareth Evans in his influential book The Varieties of Reference, have proposed that the sense of “I” needs to be elucidated, at least in part, in terms of the speaker’s sensitivity to forms of self-specifying information that have the property of being immune to error through misidentification relative to the first person pronoun. As emerges in section 3, however, this way of thinking about the sense of “I” is not compatible with the symmetry constraint, since it makes the sense of “I” private and unshareable. This leads in section 4 to an alternative proposal for doing justice to the insight that the sense of “I” reflects a distinctive way of being presented to oneself. On this proposal, the distinctive way in which I am presented to myself can be systematically related to the distinctive way in which I am presented to you. What matters is not that I am in receipt of distinctive types of information about myself, but rather that I have a distinctive ability to locate myself in objective space. On a plausible way of thinking about the individuation of cognitive abilities, this is an ability that you also can have and that underwrites both your understanding of “you” when you address me, and your understanding of “I” as uttered by me.

Forced migration changes people’s lives and their sense of self-continuity fundamentally. One memory-based mechanism to protect the sense of self-continuity and psychological well-being is autobiographical meaning making, enabling individuals to explain change in personality and life by connecting personal experiences and other distant parts of life to the self and its development. Aiming to replicate and extend prior research, the current study investigated whether autobiographical meaning making has the potential to support the sense of self-continuity in refugees. We therefore collected (...) life narratives from 31 refugees that were coded for autobiographical reasoning, self-event connections, and global narrative coherence. In line with prior research, results suggest that autobiographical meaning making relates to a higher sense of self-continuity and less psychological distress. Yet, if refugees experienced many continuing postdisplacement stressors in addition to their forced displacement, autobiographical meaning making was associated with higher self-discontinuity and greater psychological distress, especially with trauma-related symptoms such as memory intrusion and hyperarousal. Altogether, results indicate that autobiographical meaning making helps to compensate the effects of extreme biographical disruptions on the sense of self-continuity, as long as the stress caused by the biographical change is not overwhelming or too protracted.

Despite severe amnesia, some studies showed that Alzheimer Disease patients with moderate to severe dementia keep a consistent, but impoverished representation of themselves, showing preservation of the sense of identity even at severe stages of the illness. Some studies suggest that listening to music can facilitate the reminiscence of autobiographical memories and that stimulating autobiographical memory would be relevant to support the self of these patients. Consequently, we hypothesized that repeated participation to reminiscence workshops, using excerpts of familiar songs as (...) prompts would participate to the enrichment of autobiographical memories, self-representation and sense of identity. We included a group of 20 AD patients with severe dementia residing in nursing homes. Their performances were compared to a control group of 20 matched healthy residents living in the same institutions. The experiment was conducted in three phases over a 2-week period. On phase 1, an individual assessment of sense of identity was proposed to each participant. On phase 2, participants joined musical reminiscence workshops. During the third phase, individual evaluation of autobiographical memory and a second assessment of sense of identity were proposed. Our results showed that, despite their massive amnesia syndrome, autobiographical memories of AD reached at the end of the 2 weeks the number and quality of those of matched controls. Moreover, we confirmed a continuity of self-representation in AD patients with a stable profile of the answers between the first and second individual assessments of sense of identity. However, the increase in number and episodic quality of autobiographical memories was not accompanied by an enrichment of the sense of identity. In a complementary study, new patients participated in the same paradigm, but using movie extracts as prompts, and showed very similar effects. We discuss all of these results with regard to the literature showing the significant impact of repetition on the reactivation of memory traces even in very amnestic AD patients at severe stages of the disease.

In lieu of an abstract, here is a brief excerpt of the content:In Search of the Sense and the Senses:Aesthetic Education in Germany and the United StatesAlexandra Kertz-Welzel (bio)The dream that art is able to humanize human beings is very old. One person fascinated by this idea claimed:The creative artist educates and perfects through his work the nation's capacity for appreciation, just as conversely the general feeling for art thus developed and sustained creates the fruitful soil which is the (...) condition for the birth, the growth, and the activity of creative forces.1The author asserted that art has educational power and is able to improve appreciation as well as activate creative energy. Art is a way to transform the individual through its aesthetic power.Although these ideas sound similar to some approaches in arts education, this quotation does not represent the ideas of an art educator or a music educator. It is a quotation from one of the most powerful and most dangerous believers in the transforming power of art and music, in particular—Adolf Hitler (1889-1945). His ideology matched perfectly with the ideas of German music education in the 1930s, and therefore music education was a significant part of the school curriculum during the Third Reich. One of the most tempting ideas for music educators is the claim that music is capable of transforming human beings and their society.The idea of the educational power of music starts at least with Plato. Since the 1950s, aesthetic education has emphasized the aesthetic value and educational power of music. The German and the American concepts of aesthetic education are significantly different, but as a result of historical developments, they also share some similarities.The main intent of this paper is to analyze crucial issues of aesthetic education that exist in Germany and the United States. By comparing the two approaches, some core issues of music education will also be revealed in terms of idealistic dreams that are intent on making the world a better place [End Page 102] through music. This leads to some interesting insights concerning the significance but also the ambiguity of art for societies.The Roots: Ancient Greece, Schiller, and Holistic DreamsThe origin of the term aesthetics can be found in the Greek word aisthesis, which means perception through the senses.2 This meaning of aisthesis is originally not related to art. It concerns all kinds of sensations through seeing, hearing, touching, smelling, and tasting. In Greek philosophy, aisthesis as a way of experiencing the world through the senses is opposite to cognition in terms of an intellectual way of realization, the theoria. But given that art is something one can perceive through the various senses, aisthesis also concerns art.Most theories of aesthetic education refer to the ancient Greek idea of music, the musiké, which is a unity of music, dance, and literature. Plato emphasized the educational power of music and its effects on character development: "Musical training is a more potent instrument than any other, because rhythm and harmony find their way into the inward places of the soul.... "3 Since music is so powerful, the correct use and the correct kind of music are important. According to Plato, art is a way to learn about truth and ideas through beauty. But art is also dangerous, because the senses "lie" and art is only an imitation of truth. For Plato, the senses are not as clear as the intellect.Plato's concerns about the ambivalence of sensorial perception are typical for the way aisthesis and aesthetics have been understood throughout the history of philosophy. The tension between a "true" intellectual approach to knowledge and an inferior approach through the senses is one aspect of the well-known mind-body dichotomy.During the eighteenth century, the era of enlightenment, Alexander Baumgarten (1714-62) introduced the term aesthesis into the philosophical discussion.4 In his book Aesthetica (published in 1750), he attempted to justify sensorial perception and emotions as a unique way of understanding the world. Baumgarten was not interested in the arts at all and tried to establish aesthetics as the science of sensuous cognition in order to improve the sensuous capacity for cognition. Immanuel Kant (1724-1804) was the... (shrink)

The author of this little but suggestive volume believes that the "Death of God" theologians answer questions no one is asking. And for that reason he rejects in toto the kind of theology advocated by this strange breed of Christian "apologist". But MacGregor believes that theologizing about the "absence of God" is salutary for the intellectual concerns of the modern Christian. He finds references to the notion of the "hiddenness of God" in all of the reformers and especially in those (...) theologians of this century who identified their position with that of the reformers: Barth, Bonhoeffer, Tillich and others. MacGregor wants to show the methodological similarities between the notion of the deus absconditus and the emotional and intellectual inability to find God as part of the human experience. And it is an evident truth that modern man hardly gives any credence to the traditional claims that Christians make about the nearness of God hovering over His creatures like a mother-hen. MacGregor argues that the sense of the absence of God in the contemporary mood is a positive sense of absence. It is not mere indifference, but a malaise, a God-forsakenness. And the God-forsakenness is a means by which the individual faces the world courageously. There is tragedy in this attitude, even wistfulness for the beliefs of the enchanted years, but the whole thing thrusts one out to face the world as a man. MacGregor's book is one of the most stimulating pieces of popular theology to appear in a long time. The author is precise and lucid, and profoundly philosophical, but he has the marvelous gift of couching his theologizing in language and categories that can be comprehended.--W. A. J. (shrink)
