We live in an ageing society, where people are living longer, and where decreases in the birth rate mean that the proportion of the population above retirement age is steadily increasing. An ageing population has considerable implications for health services and care provision. Consequently there is a growing interest among researchers, medical practitioners, and policy makers in older adults, their capabilities, and the changes in their cognitive functioning. This book offers an up-to-the-minute account of the latest methodological and theoretical (...) issues in cognitive ageing. Part of the Debates in Psychology series, it sets out the arguments surrounding the currently controversial questions in cognitive ageing. What is the appropriate methodology for understanding cognitive change? How many factors are necessary to understand the patterns of age-related change? What might these factors be? The topics and arguments are explored in a series of chapters by the leading researchers in the field. Each contributor offers their view of how cognitive ageing can be best understood, and together they cover a broad range of cognitive functions including language use, cognitive slowing, and memory loss. Each of the chapters stands alone as the latest review of work in the area. Taken together, the chapters form a coherent theoretical debate through which the reader will learn about the dynamic nature of cognitive ageing research, and about the direction this research will be taking in the future. Models of Cognitive Aging will be an invaluable resource for anyone with an interest in the elderly, and in their cognitive abilities. (shrink)

This paper examines the representationalist view of experiences in the light of the phenomena of perfect and relative pitch. Two main kinds of representationalism are identified - environment-based and cognitive role-based. It is argued that to explain the relationship between the two theories a distinction should be drawn between various types of implicit and explicit content. When investigated, this distinction sheds some light on the difference between the phenomenology of perfect and relative pitch experiences and may be usefully applied (...) to describe the nature of experiences in the other sense modalities.

The history of philosophy is rich in diverse and sometimes directly contradictory views on the character of the relation between science and art. There have been times when art was proclaimed as lower than science, as an inadequate form of assimilation of reality by man, while at others it was seen as the sole means of adequate reflection of the world hidden "behind Maia's mysterious veil." And although today we are far from overestimating or underestimating either of the ways in (...) which man perceives reality, the fact is that the problem of the relationship between science and art remains quite acute, as is shown in particular by the broad discussion on this question that has arisen in the pages of Problems of Philosophy [Voprosy filosofii] during the last three years. The present article is an attempt to treat yet another facet of the relationships between science and art, taking as point of departure the capacity of art to model not only certain aspects of reality but human reality itself, including that of scientific theory. From this standpoint art, as a meta-activity as it were, relates to positive cognition such as philosophy not so much "horizontally" as "vertically.". (shrink)

Recently some bioethicists and neuroscientists have argued for an imperative of chemical cognitive enhancement. This imperative is usually based on consequentialist grounds. In this paper, the topic of cognitive self-enhancement is discussed from a Kantian point of view in order to shed new light on the controversial debate. With Kant, it is an imperfect duty to oneself to strive for perfecting one’s own natural and moral capacities beyond one’s natural condition, but there is no duty to enhance others. (...) A Kantian approach does not directly lead to a duty of chemical cognitive self-enhancement, but it also does not clearly rule out that this type of enhancement can be an appropriate means to the end of self-improvement. The paper shows the benefits of a Kantian view, which offers a consistent ideal of self-perfection and teaches us a lesson about the crucial relevance of the attitude that underlies one’s striving for cognitive self-improvement: the lesson of treating oneself as an end in itself and not as mere means to the end of better output.

Explaining the causal mechanisms that contribute to autism spectrum disorder occurrence remains a conundrum in developmental medicine, neuroscience, and child psychiatry. Recent research has resulted in agreement on behavioral definitions and their underlying cognitive processes, early diagnosis and standardized assessments, evidence-based interventions, systems-level approaches to neurobiology, and identification of genetic variants and their interaction with epigenetic and environmental factors. However, an explanatory model of autism causation remains elusive.Perhaps..

Objective The establishment of patient-centered measures capable of empirically determining meaningful cognitive change after surgery can significantly improve the medical care of epilepsy patients. Thus, this study aimed to develop reliable change indices (RCIs) and standardized regression-based (SRB) change norms for a comprehensive neuropsychological test battery in the German language. Methods Forty-seven consecutive patients with temporal lobe epilepsy underwent neuropsychological assessments, both before and 12 months after surgery. Practice-effect-adjusted RCIs and SRB change norms for each test score were computed. (...) To assess their usefulness, the presented methods were applied to a clinical sample, and binary logistic regression analyses were conducted to model the odds of achieving improvement in quality of life (QOL) after surgery. Results The determined RCIs at 90% confidence intervals and the SRB equations for each test score included in the test battery are provided. Cohen’s kappa analyses revealed a moderate mean agreement between the two measures, varying from slight to almost perfect agreement across test scores. Using these measures, a negative association between improvement in QOL and decline in verbal memory functions after surgery was detected (adjusted odds ratio = 0.09, p = 0.006). Significance To the best of our knowledge, this study is the first to develop RCIs and SRB change norms necessary for the objective determination of neuropsychological change in a comprehensive test battery in the German language, facilitating the individual monitoring of improvement and decline in each patients’ cognitive functioning and psychosocial situations after epilepsy surgery. The application of the described measures revealed a strong negative association between improvement in QOL and decline in verbal memory functions after surgery. (shrink)

I would like to know who of mycontemporaries should be more competent inKantian philosophy than me.(Schopenhauer in a letter to Rosenkranz and Schubert, 18371)In this paper the attempt is made to show how Schopenhauer's critique of Kant leads from initial disagreements to a fundamental modification, even a new formation, of the Kantian concepts of understanding, reason, imagination, perception, idea and thing-in-itself. The starting point and the core of his critique is the demand for the appreciation of intuitive knowledge which is (...) apart from and independent of reason. The intuitive knowledge goes back to images and its highest form is aesthetic contemplation. Without a participation of concepts it is sufficient to explain objective reality. Particularly on the basis of Schopenhauer's critical examination of Kant's schematism it can be shown that his alternative conception of an image-based objectivity of experience is to be taken seriously, even if the way he presents it sometimes gives the impression of a mere misunderstanding of Kant's theory of cognition.

How is one’s cognitive ability related to the way one responds to strategic uncertainty?

Our experiments involve two main treatments: one in which two human subjects interact, and another in which one human subject interacts with a computer program whose behavior is known. By making the behavior of the computer perfectly predictable, (...) the latter treatment eliminates strategic uncertainty. We find that subjects with higher cognitive ability are more sensitive to strategic uncertainty than those with lower cognitive ability. (shrink)

We examined how language supports the expression of temporality within sentence boundaries in English, which has a rich inventory of grammatical means to express temporality. Using a computational model that mimics how humans learn from exposure we explored what the use of different tense and aspect combinations reveals about the interaction between our experience of time and the cognitive demands that talking about time puts on the language user. Our model was trained on n-grams extracted from the BNC to (...) select the TA combination that fits the context best. It revealed the existence of two different sub-systems within the set of TA combinations, a “simplex” one that is supported lexically and is easy to learn, and a “complex” one that is supported contextually and is hard to learn. The finding that some TA combinations are essentially lexical in nature necessitates a rethink of tense and aspect as grammatical categories that form the axes of the temporal system. We argue that the system of temporal reference may be more fruitfully thought of as the result of learning a system that is steeped in experience and organised along a number of functional principles.

In lieu of an abstract, here is a brief excerpt of the content:Mild Cognitive Impairment:Which Kind Is It?Andy Hamilton (bio)Keywordshuman kinds, mild cognitive impairment, multiple personality disorder, practical kinds, social constructionThere is much stimulating material in the Graham and Ritchie's paper (2006), concerning not just disease-classification but also the ethics of diagnosis. My concern is with the way in which they adduce Ian Hacking's views in the philosophy of science in support of their own. The authors quote with (...) approval his "dynamic nominalism" and its influence on Zachar's concept of "practical kinds." Hacking's view, as the authors quote it, is that "People classified in a certain way tend to conform to or grow into the ways that they are described; but they also evolve in their own ways, so that the classifications and descriptions have to be constantly revised" (1995, 21). The act of classifying changes both the classifier and the subject of classification, resulting in facts and categories that are both socially created and real. Hacking calls this "the looping effect of human kinds," and comments that "Multiple personality [disorder] is an almost too perfect illustration of this feedback effect" (1995, 21). The authors comment that Zachar (2000) builds on Hacking's position, discarding essentialist notions of classification that are limited to inherent biological properties, and turning instead to "practical kinds—nonarbitrary cultural artifacts intended to meet pragmatic needs (e.g. therapeutic, predictive prognostic, labeling effects, and physiology)" (Graham and Ritchie 2006, 36). Practical kinds, they believe, offer a way out of the clinical approach focused on mild cognitive impairment (MCI) as a precursor to, or mild form of, Alzheimer's disease. The inclination of the authors, as I read them, is to treat MCI as a practical or human kind, and not, like Alzheimer's disease, as a natural kind.My concern is whether the "looping effect of human kinds" can be transferred to the case of MCI from Hacking's original case study in Rewriting the Soul, multiple personality disorder (MPD). Hacking wished there to undermine the traditional debate over whether MPD is a "social or psychiatric artifact." He claims, correctly I think, that the presupposition behind the question "Is MPD a real disorder as opposed to a product of social circumstances?" should be rejected. The fact that a disorder is a product of social circumstances does not make it less real (1995, 12). On the looping of human kinds, Hacking comments that "The concept of child abuse [implicated in MPD] may itself be so made and molded by attempts at knowledge and intervention, and social reaction to these studies, that there is no stable object, child abuse, to have knowledge about." This is a "no fact of the matter" response, and it [End Page 51] is based on the recognition of conceptual change. He later adds that child abuse "is a real evil, and it was so before the concept was constructed. It was nevertheless constructed. Neither reality nor construction should be in question" (1995, 61, 68). However, Hacking's conclusions about the reality of MPD express only a muted skepticism. Utilitarian skeptics approach this question by asking, "What is the most effective treatment?" Hacking writes that "in their hearts [such skeptics] suspect that the outcome of multiple therapy [therapy that condones or even encourages the development of multiples in the patient] is a type of false consciousness" (1995, 267). The skeptics about MPD are making a moral judgment, he believes; but on whether that moral judgment is correct, he is silent, although the suspicion must be that he agrees with it.How do these considerations apply to the case of MCI? Graham and Ritchie rightly note that classifying a subject as suffering from MCI, and informing them of the diagnosis, will affect them adversely—it will cause suffering not least because there is at present no cure. However, it must surely be conceded that any disease at all—physical or mental—is a social entity insofar as it involves behavioral ascriptions to the subject concerning their incapacity. The authors also note the vested interests—especially from the pharmaceutical industry—in developing a diagnostic category of MCI. These interests are present in the development of any significant diagnostic... (shrink)

In this paper I deal with the issues in Second Scholasticism of the nature, genesis and creatability of perfect vital acts of cognition and appetition in vital powers. I present the theories of Francisco Suárez (1548–1617), Raffaele Aversa (1589–1657), and Bartolomeo Mastri (1602–1673) together with Bonaventura Belluto (1603–1676). I show that while for Aversa these acts are action-like items merely emanating from the soul and vital powers and as such cannot be produced from the outside, even by God, for Mastri (...) and Belluto they are absolute qualities proceeding from their principles by efficient causation proper, which is a kind of procession that can be replaced by God. I argue that Suárez’s position attempts to steer a middle ground between these two theories. (shrink)

_Background and aims:_ Intensive mothering norms prescribe women to be perfect mothers. Recent research has shown that women’s experiences of pressure toward perfect parenting are related to higher levels of guilt and stress. The current paper follows up on this research with two aims: First, we examine how mothers regulate pressure toward perfect mothering affectively, cognitively, and behaviorally, and how such regulation may relate to parental burnout. Second, we examine how feeling pressure toward perfect mothering may spill over into mothers’ (...) work outcomes. _Methods:_ Through Prolific Academic, an online survey was sent to fulltime working mothers in the United Kingdom and United States with at least one child living at home ( N = 169). Data were analyzed using bootstrapping mediation models. _Results:_ Feeling pressure to be a perfect mother was positively related to parental burnout, and this relation was mediated by parental stress, by a stronger cognitive prevention focus aimed at avoiding mistakes as a mother, and by higher maternal gatekeeping behaviors taking over family tasks from one’s partner. Moreover, pressure toward perfect mothering had a positive direct effect on career ambitions; and a negative indirect effect, such that mothers with higher felt pressure toward perfect mothering experienced lower work-family balance, which in turn related to lower career ambitions. _Conclusion:_ The findings suggest that intensive mothering norms might have severe costs for women’s family and work outcomes, and provide insights into where to direct efforts to reduce motherhood hardships and protect women’s career ambitions.

In lieu of an abstract, here is a brief excerpt of the content:The Ambiguities of Mild Cognitive ImpairmentTim Thornton (bio)Keywordsclassification, disease, mild cognitive impairment, normative, valuesCorner and Bond's paper (2006) raises some key ethical questions about the classification and diagnosis of mild cognitive impairment (MCI). In this commentary, I wish to revise some of the general issues about the classification of mental disorder raised by this particular classificatory concept. The central issue raised is the connection between the (...) pathologic status of a condition and what I term the plain facts about the frequency and nature of its symptoms.There are a number of ethical questions raised by applying the label of MCI. Centrally, perhaps, is the concern, illustrated by the case vignettes, that a diagnosis carries negative repercussions that might outweigh the more narrowly medical advantages of an early diagnosis. But although that concern may be appropriate, such ethical complications are a danger of any psychiatric classification or diagnosis, even the most well grounded. Any psychiatric diagnosis can carry a danger of stigma, for example.What seems to make such ethical concerns more serious in this case—at least to a philosopher outsider—is the implicit further concern that MCI is not a real, objective, or, to use a more medical term, valid category or classification. If it is not valid, then any negative connotations of the diagnosis will not be outweighed by medical technological achievements. In other words, the further ethical issues are given much greater weight if the question of validity is not satisfactorily resolved.The question of the reality, objectivity, or validity of MCI can be divided into two issues:1. Is MCI a real, objective, or valid feature of psychological phenomenology?2. Is MCI a real, objective, or valid psychological illness, disease, or pathology?A condition might be a real, objective, or valid feature of psychological phenomenology without being a real illness. It might be some other aspect of human living. Szasz (1960) suggests that this is the case with mental illness (he might more properly say "so-called mental illness") as a whole. But, less controversially, the unusual ability to calculate, mentally and in a flash, the date of future Easter Sundays is a genuine feature of human living—some people possess the ability even if most do not—without either it, or its lack, being an illness. Being real as an illness is a very specific kind of being. It is this, I suggest, that raises difficulties in the case of MCI by contrast with the easier question of whether something is a genuine feature of human living in some other way. [End Page 21]From "normal" and "normative" to "correct" and "incorrect"Corner and Bond (2006) usefully suggest that the question of whether MCI is real is made more difficult by an ambiguity in the sense of the word normal. They suggest that although "physiologic and cognitive decline is assumed to be a normal experience" this still leaves "boundary problems" about "distinguishing normal aging from disease" (Corner and Bond 2006, 3–4). Thus, if the symptoms of MCI are continuous with the ordinary phenomena of physiologic and cognitive decline, then they might also be merely normal. But this does not settle the status of MCI because normal can mean either "normative, that is, usual; or it can mean nonpathologic" (Corner and Bond 2006, 4).On the assumption that MCI is at least continuous with phenomena that are normal, then its symptoms might be normal in the sense of usual but nevertheless pathologic: an inevitable illness. Or they might be usual and nonpathologic, that is, merely a feature of aging that, although regrettable, lacks the connotations of illness (e.g., the appropriateness, if not the possibility, of treatment). (In principle on the assumption in play—that the symptoms of MCI are normal—they might be unusual but nonpathologic akin, for example, to an improved ability to solve crosswords with age that might affect a small lucky proportion of the population. Perhaps such a crossword puzzler might be reassured by their doctor: "Well that is very unusual but there is no need to worry: it is not a symptom of any illness. You are perfectly normal.")Thus the question "Is MCI normal... (shrink)

This article describes the Adaptive Control of Thought–Rational (ACT–R) cognitive architecture (Anderson et al., 2004; Anderson & Lebiere, 1998) and its detailed application to the learning of algebraic symbol manipulation. The theory is applied to modeling the data from a study by Qin, Anderson, Silk, Stenger, & Carter (2004) in which children learn to solve linear equations and perfect their skills over a 6‐day period. Functional MRI data show that: (a) a motor region tracks the output of equation solutions, (...) (b) a prefrontal region tracks the retrieval of declarative information, (c) a parietal region tracks the transformation of mental representations of the equation, (d) an anterior cingulate region tracks the setting of goal information to control the information flow, and (e) a caudate region tracks the firing of productions in the ACT–R model. The article concludes with an architectural comparison of the competence children display in this task and the competence that monkeys have shown in tasks that require manipulations of sequences of elements.

The aim of this paper is to bring to light the anthropological dimension of Kant’s account of cognition as it is developed in the Lectures on Anthropology. I will argue that Kant’s anthropology of cognition develops along two complementary lines. On the one hand, it studies Nature’s intentions for the human species – the “natural” dimension of human cognition. On the other hand, it uses this knowledge to help us realise of our cognitive purposes – the “pragmatic” dimension of (...) human cognition. Insofar as it is intended for us as embodied human agents whose cognition takes place in the empirical world, it is concerned with the knowledge of the natural subjective conditions that help or hinder our cognition. Yet the idea that Kant’s anthropology of cognition has a pragmatic dimension turns out to be problematic. For whilst pragmatic anthropology is defined as ‘the investigation of what he as a free-acting being makes of himself, or can and should make of himself’ (A 7:119), by contrast with acting, cognising seems to be beyond the realm of voluntary action. However, I will show that Kant’s account of cognition makes room for a form of epistemic control that is sufficient to account for the possibility of its pragmatic dimension. Therefore, far from portraying human beings as disembodied pure minds, Kant’s account not only acknowledges the empirical, contingent and messy features of our cognition, it helps us become better, more efficient knowers by recommending how we can improve upon the subjective features that further or hinder our cognitive perfection. I will conclude by drawing the implications on my interpretation for our overall understanding of Kant’s account of cognition. (shrink)

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non-deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual-motor activity does not have (...) a privileged status with respect to memory. Soft constraints can work contrary to the designer's intentions by making the access of perfect knowledge in-the-world more effortful than the access of imperfect knowledge in-the-head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual-motor effort of accessing knowledge in-the-world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in-the-head even when the absolute difference in perceptual-motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design. (shrink)

Up to the 1960s, psychology was deeply under the influence of behaviourism, which focused on stimuli and responses, and regarded consideration of what may happen in the mind as unapproachable scientifically. This began to change with the devising of methods to try to tap into what was going on in the 'black box' of the mind, and the development of 'cognitive psychology'. With the study of patients who had suffered brain damage or injury to limited parts of the brain, (...) outlines of brain components and processes began to take shape, and by the end of the 1970s, a new science, cognitive neuroscience, was born. But it was with the development of ways of accessing activation of the working brain using imaging techniques such as PET and fMRI that cognitive neuroscience came into its own, as a science cutting across psychology and neuroscience, with strong connections to philosophy of mind. Experiments involving subjects in scanners while doing various tasks, thinking, problem solving, and remembering are shedding light on the brain processes involved. The research is exciting and new, and often makes media headlines. But there is much misunderstanding about what brain imaging tells us, and the interpretation of studies on cognition. In this Very Short Introduction Richard Passingham, a distinguished cognitive neuroscientist, gives a provocative and exciting account of the nature and scope of this relatively new field, and the techniques available to us, focusing on investigation of the human brain. He explains what brain imaging shows, pointing out common misconceptions, and gives a brief overview of the different aspects of human cognition: perceiving, attending, remembering, reasoning, deciding, and acting. Passingham concludes with a discussion of the exciting advances that may lie ahead.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

In lieu of an abstract, here is a brief excerpt of the content:Cognitive Error and Contemplative Practices:The Cultivation of Discernment in Mind and HeartWesley J. WildmanBrains are amazing organs in all creatures with central nervous systems and especially in human beings. But they are not perfect. Without forgetting the larger success story of cognitive evolution, I want to explore the way that cognitive biases sometimes produce errors in both religious and secular social settings and how such errors (...) can be diagnosed and corrected when they occur. This will involve noticing that error diagnosis and correction is a process that certain social groups have a vested interest in resisting or neglecting, in some respects, while the very same social groups may furnish resources that support the detection of cognitive errors, in other respects.This presents a moral quandary for both secular and religious groups. Should we educate children to be fully aware of their cognitive vulnerability to advertising, thereby learning how to resist and eventually become immune to one of the fundamental power sources of modern market economies? Should religious groups explain to young people their cognitive tendencies to posit the action of supernatural beings whether or not any such action exists, even though this may disrupt the power of religious groups to forge bracing social togetherness that supports psychologically useful coping skills? While I do not seek to answer such complex moral questions in this paper, I do argue that knowledge of cognitive biases and the resulting tendencies to cognitive error, self-defeating behaviors, and self-deception should be made available to those individuals and groups who are interested in promoting a high degree of critical self-awareness in the analysis of beliefs and behaviors in both secular and religious contexts.The term "error" is a potentially problematic one in that it misleadingly suggests that there might be a uniquely correct way in which cognition should work. I do not wish to suggest such a binary opposition. After all, biases exist in the human cognitive system either because they have been selected in the evolutionary process for their survival benefits or because they are side effects of other traits selected for their usefulness. My concern is with the wondrous human discovery that we can analyze [End Page 61] our behaviors and beliefs with such precision that we can sometimes detect when our cognitive biases produce mistaken beliefs and self-defeating behaviors. This forms the basis for my contention that cognition can often work better than it does—more accurately, less self-destructively—when tendencies to cognitive error are diagnosed, corrected, and perhaps even systematically resisted.The profound irony here is that the very same social groups (secular and religious) with an obvious vested interest in resisting such enlightenment in some respects can also promote processes of discernment and insight in other respects. Existing literature in the cognitive psychology of religion rarely bothers with such subtleties. It is common to assume that simply to notice the operation of cognitive biases in religion—say, in supporting belief in supernatural entities who providentially interact in human affairs, or in establishing and reinforcing people's willingness to defer to certain kinds of religious authority—is at the same time to establish the presence of rampant cognitive error, massive resistance to diagnosing and correcting it, and thus the infliction of pernicious cruelties on young children who have no way of escaping the resulting irrational indoctrination.This moral reflex to condemn religious groups because of their characteristic reluctance to acknowledge the role of cognitive biases in their beliefs and practices is understandable given the irrationality, ignorance, or denial that such reluctance suggests. I frankly acknowledge that I share this moral concern. But the actual complexities of religious practice demonstrate that the situation demands a subtler evaluation. Resistance to awareness of cognitive biases exists both inside and outside religious groups; economic and political practices in all eras and of all types have every bit as much to gain from neglecting to enlighten people about their cognitive operations as religious groups do—just consider the techniques employed in commercial advertising and political campaigns. Moreover, religious groups also promote methods of discernment and self-awareness that have historically been, and continue to be, the dominant method by which... (shrink)

Seeing happens effortlessly and yet is endlessly complex. Among the most fascinating aspects of visual perception is its stability and constancy. As we shift our gaze or move about the world, the light projected onto the retinas is constantly changing. Yet the surrounding objects appear stable in their properties. Psychologists have long been interested in the constancies. They have asked questions such as: How good is constancy? Is constancy a fact about how things look, or is it a product of (...) our beliefs and judgments about how things look? How can the contents of visual experience be studied experimentally? Philosophers have long been interested in characterizing visual experience and have become widely interested in the constancies more recently. As psychologists and philosophers have interacted, new questions have arisen: If experience is not as of retinal stimulation (proximal mode), but does not always exhibit constancy (or at least not in all respects), how shall we describe this intermediate state? Also, should we regard any departure from constancy as a failure of the visual system, or might it be a reasonable or adaptive response? In what circumstances is seeing highly conditioned by cognitive factors such as background assumptions, and in what circumstances not? Our volume focuses on size constancy and color constancy. It considers methodologies for studying conscious visual perception, efforts to describe visual experience in relation to constancy, what it means that constancy is not always perfect, and the conceptual resources needed for explaining visual experience.

Moreover, social-norm policing of cosmopolitan colonies coordinates farmer decisions, phenotypes, and ownership identities with bacteria herding, privatization, and consumption.

In this article, I explore the auditory technopolitics of prenatal sound systems, asking what kinds of futures, listeners and temporalities they seek to produce. With patents for prenatal audio apparatus dating back to the late 1980s, there are now a range of devices available to expectant parents. These sound technologies offer multiple benefits: from soothing away stress to increasing the efficiency of ultrasonic scans. However, one common point of emphasis is their capacity to accelerate foetal ‘learning’ and cognitive development. (...) Taking as exemplary the Babypod and BabyPlus devices, I argue that prenatal sound systems make audible a particular figuration of pregnancy and gestational labour that combines divergent notions of responsibility and passivity. Contra the equation of neoliberalism with self-control and individualism, I argue that prenatal sound systems amplify neoliberal capitalism’s elision of personal, maternal and familial responsibility. As reproductive sound technologies, prenatal sound systems facilitate maternal–familial investment in the pre-born as future-child. Consequently, financialised notions of inheritance are substituted for biological inheritance. Drawing attention to the common rhetorical figuration of the sonic as womb-like, furthermore, I argue that prenatal sound systems exemplify what I refer to as uterine audiophilia. By treating the womb as ‘the perfect classroom’, prenatal sound systems imply an intense maternal obligation to invest in and impress upon the future-child, while also envisioning the pregnant person’s body as an occupied, resonant space. Cohering with a fidelity discourse that posits the reproductive medium as passive container and a source of noise that is to be overcome, uterine audiophilia relies upon politically regressive conceptualisations of pregnancy. I thus argue that these devices mark the hitherto under-theorised convergence of auditory culture, technology and reproductive politics. (shrink)

Citing an epistemic or cognitive asymmetry between experts and the public, it is easy to view the relation between scientists and citizens as primarily based on trust, rather than on the content of expert argumentation. In criticism of this claim, four theses are defended: Empirical studies suggest that content matters, while trust boasts persuasiveness. In social policy controversies, genuine expert-solutions are normally not available; if trust is important here, then a clear role for cognitive asymmetry is wanting. Social (...) policy controversies pivot on values, so that biases and ideologies may explain participant behavior. Few experts communicate perfectly; rather than cognitive ones, one might cite social differences. (shrink)

Homesign is a visual–gestural form of communication that emerges between deaf individuals and their hearing interlocutors in the absence of a conventional sign language.

Agenda Relevance is the first volume in the authors' omnibus investigation of the logic of practical reasoning, under the collective title, A Practical Logic of Cognitive Systems. In this highly original approach, practical reasoning is identified as reasoning performed with comparatively few cognitive assets, including resources such as information, time and computational capacity. Unlike what is proposed in optimization models of human cognition, a practical reasoner lacks perfect information, boundless time and unconstrained access to computational complexity. The practical (...) reasoner is therefore obliged to be a cognitive economizer and to achieve his cognitive ends with considerable efficiency. Accordingly, the practical reasoner avails himself of various scarce-resource compensation strategies. He also possesses neurocognitive traits that abet him in his reasoning tasks. Prominent among these is the practical agent's striking (though not perfect) adeptness at evading irrelevant information and staying on task. On the approach taken here, irrelevancies are impediments to the attainment of cognitive ends. Thus, in its most basic sense, relevant information is cognitively helpful information. Information can then be said to be relevant for a practical reasoner to the extent that it advances or closes some cognitive agenda of his. The book explores this idea with a conceptual detail and nuance not seen the standard semantic, probabilistic and pragmatic approaches to relevance; but wherever possible, the authors seek to integrate alternative conceptions rather than reject them outright. A further attraction of the agenda-relevance approach is the extent to which its principal conceptual findings lend themselves to technically sophisticated re-expression in formal models that marshal the resources of time and action logics and label led deductive systems. Agenda Relevance is necessary reading for researchers in logic, belief dynamics, computer science, AI, psychology and neuroscience, linguistics, argumentation theory, and legal reasoning and forensic science, and will repay study by graduate students and senior undergraduates in these same fields. Key features: relevance action and agendas practical reasoning belief dynamics non-classical logics labelled deductive systems. (shrink)

Berkeley and Kant are known for having developed philosophical critiques of materialism, critiques leading them to propose instead an epistemology based on the coherence of our mental representations. For all that the two had in common, however, Kant was adamant in distinguishing his own " empirical realism " from the immaterialist consequences entailed by Berkeley's attack on abstract ideas. Kant focused his most explicit criticisms on Berkeley's account of space, and commentators have for the most part decided that Kant either (...) misunderstood or was simply unfamiliar with the Bishop's actual position. Rather than demonstrate that Kant understood Berkeley perfectly well—an argument that has already been forcefully made by Colin Turbayne—I want to take a different tack altogether. For it is by paying attention to Berkeley's actual account of space, an account oriented by his rejection of spatial " geometers " like Descartes, and spatial " absolutists " like Newton, that we discover an account of embodied cognition, of spatial distance and size that can only be known by way of the body's motion and touch. Perhaps even more striking, I will want to suggest, is the manner in which Kant's approach to the problem of incongruent counterparts will equally need to rely on a proprioceptive cognition, one requiring a different geometry of position altogether. My discussion proceeds in three stages, with stage one focused on Kant's efforts to distinguish his philosophical project from Berkeley's own idealist system, and stages two and three describing the manner in which their approach to spatial orientation both challenges and extends the traditional narrative of their differences as laid out in stage one.

This work is an initial step toward developing a cognitive theory of cyber deception. While widely studied, the psychology of deception has largely focused on physical cues of deception. Given that present‐day communication among humans is largely electronic, we focus on the cyber domain where physical cues are unavailable and for which there is less psychological research. To improve cyber defense, researchers have used signaling theory to extended algorithms developed for the optimal allocation of limited defense resources by using (...) deceptive signals to trick the human mind. However, the algorithms are designed to protect against adversaries that make perfectly rational decisions. In behavioral experiments using an abstract cybersecurity game (i.e., Insider Attack Game), we examined human decision‐making when paired against the defense algorithm. We developed an instance‐based learning (IBL) model of an attacker using the Adaptive Control of Thought‐Rational (ACT‐R) cognitive architecture to investigate how humans make decisions under deception in cyber‐attack scenarios. Our results show that the defense algorithm is more effective at reducing the probability of attack and protecting assets when using deceptive signaling, compared to no signaling, but is less effective than predicted against a perfectly rational adversary. Also, the IBL model replicates human attack decisions accurately. The IBL model shows how human decisions arise from experience, and how memory retrieval dynamics can give rise to cognitive biases, such as confirmation bias. The implications of these findings are discussed in the perspective of informing theories of deception and designing more effective signaling schemes that consider human bounded rationality.

This paper criticizes the role of intuition-based ascriptions of cognition that are closely related to the ascription of mind. This practice hinders the explication of a clear and stable target domain for the cognitive sciences. To move forward, the proposal is to cut the notion of cognition free from such ascriptions and the intuition-based judgments that drive them. Instead, cognition is reinterpreted and developed as a scientific concept that is tied to a material domain of research. In this reading, (...) cognition becomes a changeable theoretical concept that can and must be adapted to the findings within this target domain. Taking humans as the best-established existing example of the relevant material target domain, this central case is extended to include all living systems. To clarify what it is about living systems that warrants their role as cognitive target domain, the new concept of cobolism is introduced as a complement to metabolism. Cobolism refers to the systematic ways in which each living system encompasses structures, processes and external events that maintain the fundamental metabolic processes that constitute the core of each living system. Cobolism is perfectly general, applies to bacterial and human cases alike, and provides a general format to describe wildly different cognitive organizations. It provides a clear target for the cognitive sciences to work on, turning them into what we can call the cognitive life sciences. (shrink)

Most biologists and some cognitive scientists have independently reached the conclusion that there is no such thing as learning in the traditional “instructive‘ sense. This is, admittedly, a somewhat extreme thesis, but I defend it herein the light of data and theories jointly extracted from biology, especially from evolutionary theory and immunology, and from modern generative grammar. I also point out that the general demise of learning is uncontroversial in the biological sciences, while a similar consensus has not yet (...) been reached in psychology and in linguistics at large. Since many arguments presently offered in defense of learning and in defense of “general intelligence‘ are often based on a distorted picture of human biological evolution, I devote some sections of this paper to a critique of “adaptationism,‘ providing also a sketch of a better evolutionary theory. Moreover, since certain standard arguments presented today as “knock-down‘ in psychology, in linguistics and in artificial intelligence are a perfect replica of those once voiced by biologists in favor of instruction and against selection, I capitalize on these errors of the past to draw some lessons for the present and for the future.

Models of biological and political systems share in common an irreconcilable tension. They must extract the essential features of the system to make its workings comprehensible to the human observer, and yet the omitted underbrush is essential to the workings of the system. A good model accommodates both the workings of the system and the cognitive makeup of the observer.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Cognition and Commitment in Hume's PhilosophyTimothy M. CostelloeDon Garrett. Cognition and Commitment in Hume's Philosophy. Oxford: Oxford University Press, 1997. Pp. 270. Cloth, $49.95Given that the Hume literature abounds in interpretive disagreements, it is striking to read of Don Garrett's aim "to solve... to be the last word about... [a] set of problems that have long stood in the way of understanding Hume's philosophy" (10); and, as if (...) that were not enough, to see him defining success in terms of grasping Hume's aims, understanding his arguments, and explicating conclusions and interrelations between them (8-9). Somewhere between honesty and hubris, Garrett then investigates various "puzzles" within Hume scholarship. The first three chapters undertake work of clarification. The first addresses "imagination" and "understanding," emphasizing Hume's "rejection of the intellect" within rationalist and empiricist thought, before raising difficulties with and offering solutions to Hume's use of the terms. Garrett then distinguishes five types of empiricism which "produce and reinforce" Hume's status as a cognitive psychologist developing a "theory of representational faculties" (39). Chapters two and three examine Hume's "fundamental principles" (Copy Principle and Separablity Principle) leading Garrett into informative discussions of various doctrines—space and time (152ff), the missing shade of blue (50-53, 73), and "distinctions of reason" (59ff)—arguing that none contradict the principles in question. At the end of the chapter, Garrett concludes Hume's interest in both principles lies less in doctrines each "forbids" than in "investigations... [each] motivates" (75).Armed with a battery of distinctions, the remaining chapters focus on seven such "investigations," each situating the problem, reconstructing Hume's arguments, considering extant interpretations, and offering original solutions to the puzzles posed. In chapter five, for example, Garrett argues that Hume endorses two definitions of "cause," which, neither logically equivalent nor co-extensive, involves Hume in contradiction. Having considered and rejected interpretations by other commentators, Garrett proposes a solution: Since Hume holds both that a "relation" exists only where two or more relations are compared (102-4); and that necessary connection involves "pairs of objects" and "ideas of pairs" (105-6), cause and effect can be defined either as constant conjunction or association. The "contradiction" thus removed, Garrett supports [End Page 441] his case by arguing that since Hume accepts two definitions of "virtue" (107ff.), he can do the same with causality. Finally, Garrett raises four objections to his conclusion and, responding to each, completes his solution to the Humean puzzle.As scholarly and engaging as Garrett's book is, however, the spirit of Hume is often missing from its pages. Although important, an approach which focuses on discrete fundamental principles, sets and solves puzzles, and transforms philosophical prose into lists of numbered propositions, belies Hume as a thinker obsessed with the medium of his message. Philosophy, in Hume's view, is also a matter of taste and character; a way of being and thinking which, as Garrett acknowledges, is integral to the "conduct of...[Hume's] life" (241).No single study can capture Hume's philosophy in its entirety. Yet a book claiming the "last word" might acknowledge the necessary partiality of its approach especially when it affects its own conclusions. First, with few exceptions, Garrett makes almost perfect sense of everything Hume says; and even when found wanting, it is "less philosophically vitiating that one might expect" (39). Charitable readings and Hume's greatness, notwithstanding, for his work to be free of all contradiction would be extraordinary. Second, Garrett's "puzzles" are not always genuine. Emphasizing, for example, how Hume's definitions of cause are the same thing viewed from different perspectives might prevent such a puzzle arising at all; and the evidence for Hume's putative "propositional theory of moral evaluation" is so thin (191) that one suspects Garrett's method to have a hand in generating the alleged contradiction.The same is true of the concluding chapter. Presenting the "puzzle" as a contradiction between skepticism and science, and looking to "human reason" for solace (207), it comes as no surprise that Hume's skepticism should ground and reconfirm "our commitment to reason and its products" (208). Hume's... (shrink)

If mathematics is the purest form of knowledge, the perfect foundation of all the hard sciences, and a uniquely precise discipline, then how can the human brain, an imperfect and imprecise organ, process mathematical ideas? Is mathematics made up of eternal, universal truths? Or, as some have claimed, could mathematics simply be a human invention, a kind of tool or metaphor? These questions are among the greatest enigmas of science and epistemology, discussed at length by mathematicians, physicians, and philosophers. But, (...) curiously enough, neuroscientists have been absent in the debate, even though it is precisely the field of neuroscience—which studies the brain’s mechanisms for thinking and reasoning—that ought to be at the very center of these discussions. How our Emotions and Bodies are Vital for Abstract Thought explores the unique mechanisms of cooperation between the body, emotions, and the cortex, based on fundamental physical principles. It is these mechanisms that help us to overcome the limitations of our physiology and allow our imperfect, human brains to make transcendent mathematical discoveries. This book is written for anyone who is interested in the nature of abstract thought, including mathematicians, physicists, computer scientists, psychologists, and psychiatrists. (shrink)

Leibniz is unclear about the nature of pleasure. In some texts, he describes pleasure as a perception of perfection, while in other texts he describes pleasure as being caused by a perception of perfection. In this article, I disambiguate two senses of “perception of perfection”, which clarifies Leibniz’s considered position. I argue that pleasure is a perception of an increase in a substance’s power which is caused by a substance’s knowledge of a perfection of the universe (...) or God. This reading helps clarify the nature of Leibnizian happiness. Happiness is a cognitive process (akin to a mood), constituted fundamentally out of pleasure, which is grounded in increases in a substance’s power. A rational substance will sustain its happiness so long as it is more powerful than it is weak, and it is engaging in activities that increase its power. (shrink)

Christiansen & Chater (C&C) have taken the interactionist approach to linguistic universals to an extreme, adopting the metaphor of language as an organism. This metaphor adds no insights to five decades of analyzing language universals as the result of interaction of linguistically unique and general cognitive systems. This metaphor is also based on an outmoded view of classical Darwinian evolution and has no clear basis in biology or cognition.

One of the most important concepts Baumgarten introduces in his Reflections on Poetry is the concept of sensible perfection. It is surprising that Baumgarten does not elaborate upon this concept in his Metaphysics, since it plays such an important role in the new science of aesthetics that he proposes at the end of the Reflections on Poetry and then further develops in the Aesthetics. This article considers the significance of the absence of sensible perfection from the Metaphysics and (...) its implications for Baumgarten’s aesthetics, before tuming to the use Meier and Kant make of Baumgarten’s concept. In the end, this article shows that Baumgarten did not abandon his conception of sensible perfection in the Metaphysics, though its influence declined significantly after Kant rejected the idea that sensibility and the understanding could be distinguished by the perfections of their cognition.

This book presents an analysis of how speakers of typologically diverse languages report present-time situations. It begins from the assumption that there is a restriction on the use of the present tense to report present-time dynamic/perfective situations, while with stative/imperfective situations there are no such alignment problems. Astrid De Wit brings together cross-linguistic observations from English, French, the English-based creole language Sranan, and various Slavic languages, and relates them to the same phenomenon, the 'present perfective paradox'. The proposed analysis is (...) founded on the assumption that there is an epistemic alignment constraint preventing the identification and reporting of events in their entirety at the time of speaking. This book discusses the various strategies that the aforementioned languages have developed to resolve this conceptual difficulty, and demonstrates that many of the features of their tense-aspect systems can be regarded as the result of this conflict resolution. It also offers cognitively plausible explanations for the conceptual structures underlying the interactions attested between tense and aspect. (shrink)

This chapter describes Immanuel Kant's conception of anthropology and the most basic distinctions he draws when invoking faculties throughout the anthropology transcripts. It explains Kant's account of the objective senses (hearing, sight, and touch), and shows that the sensory material provided by these senses are empirical conditions of experience that supplement the a priori conditions articulated in the Critique of Pure Reason. The chapter also describes some of the central details of Kant's account of the imagination, focusing on his distinction (...) between wit and the power of judgment and on the law of association he endorses. It outlines Kant's account of both the deficiencies of the mind and the perfection of cognition. By showing how the transcendental faculties are manifested at the level of actual, concrete experience, the anthropology transcripts can help to illuminate Kant's understanding of the operations and functions of the human mind.

The main purpose of this study is to probe into the human capacity of understanding systems and defects in human knowledge of the world. The study addresses the greyness levels and systems levels and explains why the world cannot be perceived as a purely white or black structure. It also clarifies why human knowledge of systems always remains grey. The investigation relies on logical and deductive reasoning and uses the theoretical foundations of systems thinking and Boulding’s systems hierarchy. The most (...) important argument that this study advances is that human knowledge, in any form or under any circumstances, is grey and incomplete and will remain grey. Because the notion of “perfect knowledge” is ambiguous given human epistemic limits, any proportion of knowledge is incomplete and prone to change. Less complexity could lead to more accurate predications, but even in the simplest forms of systems, reaching perfect knowledge seems to be an unwarranted claim. Furthermore, because our perception of past events is incomplete, we cannot predict the future with certainty, as a result of which both the past and the future appear grey to us. The world, as an integrated system, is neither black nor white, but it remains grey, and the systems partially recognized by humans are part of the grey world. Gaining knowledge and increasing discoveries only contribute to the grey systems that are already known. (shrink)

This research study focuses on the problem of populistic propaganda online. In particular, this research study provides three case studies gathered in a Facebook Group of the Italian populistic movement Movimento 5 Stelle. On the one hand, the three case studies provide three powerful counterexamples to the thesis that online media are purposeful aggregator of people. In fact, this research study finds that online media are the perfect environment for populism to thrive. For online media seem to foster the aggregation (...) of people into groups whose main common denominator is the total refusal of anything that opposes the groups’ views. On this basis, this paper provides evidence that online media may impoverish democratic confrontation. On the other hand, this paper finds that the one of the causes of the rapid rise of populistic movements in Western countries might also be related to the problem of cognitive biases. Indeed, the case studies presented in the paper posit the existence of something that is addressed as the trigger effect, i.e. agents’ tendency to react impulsively to any kind of content that fits agent’s views about current events. Specifically, this research study finds that the activation of the trigger effect might be a direct consequence of the activation of the narrow framing bias and of the anchoring heuristic in presence of fake news.

Negative acknowledgement is an impression management technique that uses the admission of an unfavourable quality to mitigate a negative response. Although the technique has been clearly demonstrated, the underlying process is not well understood. The current research identifies a key mediator and moderator while also demonstrating that the effect extends beyond the specific acknowledged domain to the overall evaluation of a target object. The results of study 1 indicate that negative acknowledgement works through mitigating negatively valenced cognitive responses. People (...) who are presented with a negative acknowledgement are less likely to counterargue when forming an evaluation. The results of study 2 reveal that individual differences in need for structure impact the effectiveness of the technique. People who are high in need for structure are more susceptible to the effect presumably because of their desire for easy-to-use information that aids the formation and maintenance of simple knowledge structures.

This vigorously written and clearly argued Bradford Book is a must for anyone interested in intentionality, functionalism, and the status and prospects of scientific and folk psychology. It is a measure of how much has changed in the philosophy of psychology that the familiar arguments--masterfully marshalled and extended here-against the reducibility of everyday psychological statements to statements about brain states within an experimental cognitive science are here, for Stich, arguments against folk psychology. The experimental behaviorists are understood as having (...) issued the revolutionary, and reasonably justified, claim that our everyday folk psychological talk is simply false: false in much the way of demonology in that the things folk psychology talks about simply are not there. What helped us to be less troubled by this claim was analytic or logical behaviorism: folk psychological talk was perfectly viable because it really was just short-hand dispositional talk about behavior. Using beliefs as a central stalking horse, Stich argues, as recent eliminative materialists like the Churchlands, that it may well be that the terms of folk psychology have no referents. In brief, there simply may be no such things as beliefs, any more than there are devils, though of course there are all sorts of interesting phenomena that have led us to talk as if there were such. Beliefs are not in the head, nor anywhere else either. (shrink)

Carey has argued that there is a system of core numerical cognition – the analog magnitude system – in which cardinal numbers are explicitly represented in iconic format. While the existence of this system is beyond doubt, this paper aims to show that its representations cannot have the combination of features attributed to them by Carey. According to the argument from abstractness, the representation of the cardinal number of a collection of individuals as such requires the representation of individuals as (...) such, and this in turn requires non-iconic format, from which it is concluded that the explicit representation of the cardinal number of some individuals requires non-iconic representational format. In support of the first premise, an account is given of what approximate cardinal numbers might be, and in support of the second, a direct argument is articulated and defended. Finally, in response to an objection, a second argument for the central thesis is provided. While the discussion is couched in the terms of Carey’s work, the considerations it adduces are perfectly general, and the conclusion should therefore be taken into consideration by all those aiming to characterize the AM system.

In this study the influence of irrational beliefs and perfectionism on the emergence of competitive anxiety was investigated. While previous studies indicate that higher irrational beliefs predict greater competitive anxiety, in the present study it is hypothesized that this relationship is mediated by perfectionism. A serial atemporal multiple mediation analysis revealed that both adaptive and maladaptive perfectionism were significant partial mediators between irrational beliefs and competitive anxiety. The total score and all four subscale scores on irrational beliefs had both direct (...) and indirect effects on cognitive competitive anxiety, the latter effects mediated by both forms of perfectionism. Depreciation beliefs had a direct effect, and demandingness and awfulizing had indirect effects, on somatic competitive anxiety when both forms of perfectionism were entered as mediators. These findings suggest that both irrational beliefs and perfectionism influence the emergence of competitive anxiety, therefore rational emotive behavioral therapy with a focus upon perfectionism may be an effective means of reducing competitive anxiety in athletes.
