Chemotherapy is one of the most common treatments used in cancer therapy despite its serious side effects, which remain a huge concern. To the most common side effects include memory and concentration problems as well as changes in taste. This paper presents a very preliminary study focusing on cognitive dysfunction after chemotherapy in breast cancer. This phenomenon, called Cancer-Related Cognitive Dysfunction, is a frequent occurrence. The obtained results prove the impact of chemotherapy on the participant’s ability to concentrate. (...) The QEEG method and digital data analysis were used as the measurement methods. (shrink)

There is a wealth of data on the perceptual and cognitive capacities of infants strongly supporting early nativistic influences on development. Without considering these initial determinants, constructivist models of development are at best incomplete.

Synthesizing the domains of investigation highlighted in current research in distributed cognition and related fields, this paper offers an initial taxonomy of the overlapping types of resources which typically contribute to distributed or extended cognitive systems. It then outlines a number of key dimensions on which to analyse both the resulting integrated systems and the components which coalesce into more or less tightly coupled interaction over the course of their formation and renegotiation.

The rise of cognitive neuroscience is the most important scientific and intellectual development of the last thirty years. Findings pour forth, and major initiatives for brain research continue. The social sciences have responded to this development slowly--for good reasons. The implications of particular controversial findings, such as the discovery of mirror neurons, have been ambiguous, controversial within neuroscience itself, and difficult to integrate with conventional social science. Yet many of these findings, such as those of experimental neuro-economics, pose very (...) direct challenges to standard social science. At the same time, however, the known facts of social science, for example about linguistic and moral diversity, pose a significant challenge to standard neuroscience approaches, which tend to focus on "universal" aspects of human and animal cognition. A serious encounter between cognitive neuroscience and social science is likely to be challenging, and transformative, for both parties. Although a literature has developed on proposals to integrate neuroscience and social science, these proposals go in divergent directions. None of them has a developed conception of social life. This book surveys these issues, introduces the basic alternative conceptions both of the mental world and the social world, and show how, with sufficient modification, they can be fit together in plausible ways. The book is not a "new theory " of anything, but rather an exploration of the critical issues that relate to the social aspects of cognition which expands the topic from the social neuroscience of immediate interpersonal interaction to the whole range of places where social variation interacts with the cognitive. The focus is on the conceptual problems produced by any attempt to take these issues seriously, and also on the new resources and considerations relevant to doing so. But it is also on the need for a revision of social theoretical concepts in order to utilize these resources. The book points to some conclusions, especially about how the process of what was known as socialization needs to be understood in cognitive science friendly terms. But there is no attempt to resolve the underlying issues within cognitive science, which will doubtless persist. (shrink)

One sceptical rejoinder to those who claim that sensory perception is cognitively penetrable is to appeal to the involvement of attention. So, while a phenomenon might initially look like one where, say, a perceiver’s beliefs are influencing her visual experience, another interpretation is that because the perceiver believes and desires as she does, she consequently shifts her spatial attention so as to change what she senses visually. But, the sceptic will urge, this is an entirely familiar phenomenon, and it hardly (...) involves some special or theoretically important cognitive effect on sensory perception. Even supposing that the sceptic is correct about cases that are accurately described in this way, the rejoinder oversimplifies the possible roles that attention may play in mediating cognition and perception. This paper aims to identify these different roles, and by emphasis on empirical research on feature-based and object-based attention. What emerges is a plausible and well- evidenced mental schema that describes attention -mediated cognitive penetration. At the very least, the burden of proof is shifted to the sceptic, as he then must show that there are no mental phenomena involving attention in the more nuanced ways described here. One additional benefit of this analysis is that it illuminates various features of attention and its relation to both cognition and phenomenal consciousness. Therefore the analysis should be of interest to a broad range of theorists of the mind, and not just those invested in the cognitive penetration debate. (shrink)

Geven, Ben‐Shakhar, Kindt and Verschuere point out that research on deception detection usually employs instructed cheating. They experimentally demonstrate that participants show slower reaction times for concealed information than for other information, regardless of whether they are explicitly instructed to cheat or whether they can freely choose to cheat or not. Finding this ‘cognitive signature of lying’ with self‐initiated cheating too is argued by the authors to strengthen the external validity of deception detection research. [75].

Cognitive approaches contribute to our understanding of delusions by providing an explanatory framework that extends beyond the personal level to the sub personal level of information-processing systems. According to one influential cognitive approach, two factors are required to account for the content of a delusion, its initial adoption as a belief, and its persistence. This chapter reviews Bayesian developments of the two-factor framework.

According to the popular Grounded Cognition Model (GCM), the sensory and motor features of concepts, including word meanings, are stored directly within neural systems for perception and action. More precisely, the core claim is that these concrete conceptual features reuse some of the same modality-specific representations that serve to categorize experiences involving the relevant kinds of objects and events. Research in semantic typology, however, has shown that word meanings vary significantly across the roughly 6500 languages in the world. I argue (...) that this crosslinguistic semantic diversity has significant yet previously unrecognized theoretical consequences for the GCM. In particular, to accommodate the typological data, the GCM must assume that the concrete features of word meanings are not merely stored within sensory/motor brain systems, but are represented there in ways that are, to a nontrivial degree, language-specific. Moreover, it must assume that these conceptual representations are also activated during the nonlinguistic processing of the relevant kinds of objects and events (e.g., during visual perception and action planning); otherwise, they would not really be grounded, which is to say, embedded inside sensory/motor systems. Crucially, however, such activations would constitute what is traditionally called linguistic relativity—that is, the influence of language-specific semantic structures on other forms of cognition. The overarching aim of this paper is to elaborate this argument more fully and explore its repercussions. To that end, I discuss in greater detail the key aspects of the GCM, the evidence for crosslinguistic semantic diversity, pertinent work on linguistic relativity, the central claim that the GCM entails linguistic relativity, some initial supporting results, and some important limitations and future directions.

Knowledge of what it’s like to have perceptual experiences, e.g. of what it’s like to see red or taste Turkish coffee, is phenomenal knowledge; and it is knowledge the substantial or significant nature of which is widely assumed to pose a challenge for physicalism. Call this the New Challenge to physicalism. The goal of this paper is to take a closer look at the New Challenge. I show, first, that it is surprisingly difficult to spell out clearly and neutrally what (...) the New Challenge is in fact urging the physicalist to explain. What initially look like plausible or promising ways of making sense of it turn out to be either question begging or insufficient to generate a challenge to physicalism at all. I go on to suggest that what the New Challenge may be asking the physicalist to explain may be the fact that we come to token certain higher-order judgments about the significance of phenomenal knowledge. I end with a discussion of the implications of this interpretation of the New Challenge—which turns out to be as much a challenge for the anti-physicalist as it is for the physicalist. (shrink)

The relationship between knowledge, belief, and ethics is an inaugural theme in philosophy; more recently, under the title “ethics of belief” philosophers have worked to develop the appropriate methodology for studying the nexus of epistemology, ethics, and psychology. The title “ethics of belief” comes from a 19th-century paper written by British philosopher and mathematician W.K. Clifford. Clifford argues that we are morally responsible for our beliefs because each belief that we form creates the cognitive circumstances for related beliefs to (...) follow, and we inevitably influence each other through those beliefs. This study argues that recent cognitive research supports Cliffordian insights regarding patterns of belief formation and social influence. From the confirmation offered by such research, it follows that informational accuracy holds serious ethical significance in public discourse. Although scientific and epistemological matters are not always thought to be linked to normative morality, this study builds on Clifford's initial insights to show their linkage is fundamental to inquiry itself. In turn, Clifford's ethical and epistemic outline can inform a framework grounded in “public reason” under which seemingly opposed science communication strategies are philosophically united. With public discourse on climate change as the key example, empirically informed and grounded strategies for science communication in the public sphere are considered. (shrink)

_Abstract_: We imagine the future of cognitive science by first considering its past, which shows remarkable transformation from a field that, although interdisciplinary, was initially marked by a narrow set of assumptions concerning its subject matter. In the last decades, multiple alternative frameworks with radically different ontological and epistemic commitments (e.g., situated cognition, embodied cognition, extended mind) found broad support. We address the question of how to understand these changes, noting as logical alternatives that (1) newer approaches are not (...) properly _cognitive_; (2) that newer approaches are cognitive but not _science_; and (3) that cognitive science has become pluralistic. We endorse the third position and venture to guess that the future of cognitive science is also pluralistic. We are left, however, with the question of what this _means. _After noting the polysemous nature of the term “pluralism”, we attempt to add clarity by distinguishing three forms: ontological, epistemic, and ethical. We then consider what each form might imply for the future of cognitive science. _Keywords_: Cognitive Science; Pluralism; Relativism; History of Science; Philosophy of Science _Il futuro della scienza cognitiva è pluralista, ma che vuol dire?_ _Riassunto_: Pensiamo al futuro della scienza cognitiva in primo luogo considerando il suo passato, il quale è notevolmente cambiato rispetto al presente. Per quanto si proponesse come un campo di studi interdisciplinari, la scienza cognitiva delle origini era caratterizzata da un insieme ristretto di assunzioni riguardanti il proprio oggetto. Negli ultimi decenni hanno trovato supporto diverse cornici teoriche in reciproca competizione e con impegni ontologici ed epistemologici radicalmente differenti (si pensi, per esempio, alla cognizione situata, alla cognizione incarnata, alla mente estesa). Proveremo a dare risposta alla domanda su come intendere questi cambiamenti, prendendo atto che ci troviamo di fronte a una serie di posizioni che sono logicamente alternative fra loro: (1) gli approcci più recenti non sono propriamente _cognitivi_; (2) oppure che gli approcci più recenti sono cognitivi, ma non _scientifici_; (3) la scienza cognitiva è diventata pluralista. Noi crediamo che la terza posizione sia corretta e scommettiamo su un futuro della scienza cognitiva che sia anche pluralista. Resta aperto, tuttavia, il problema di cosa questo _significhi_. Dopo aver preso atto della natura polisemica del termine “pluralismo”, cercheremo di far chiarezza distinguendo tre forme di pluralismo: ontologico, epistemico, ed etico. Considereremo quindi ciò che ciascuna può comportare per il futuro della scienza cognitiva. _Parole chiave_: Scienza cognitiva; Pluralismo; Relativismo; Storia della scienza; Filosofia della scienza.

Fodor claims that cognitive modules can be thought of as constituting a psychological natural kind in virtue of their possession of most or all of nine specified properties. The challenge to this considered here comes from synaesthesia. Synaesthesia is a type of cross-modal association: input to one sensory modality reliably generates an additional sensory output that is usually generated by the input to a distinct sensory modality. The most common form of synaesthesia manifests Fodor's nine specified properties of modularity, (...) and hence, according to Segal (1997), it should be understood as involving an extra module. Many psychologists believe that synaesthesia involves a breakdown in modularity. After outlining how both theories can explain the manifestation of the nine alleged properties of modularity in synaesthesia, I discuss the two concepts of function which initially motivate the respective theories. I argue that only a teleological concept of function is properly able to adjudicate between the two theories. The upshot is a further application of so-called externalist considerations to mental phenomena. (shrink)

Neuroconstructivism postulates the progressive complexity of mental representation over the course of cognitive development and the role of the graphic representation of movement in the transformation of mental schemas, cognitive flexibility, and representational complexity. This study aims to: understand children’s resources in the drawing of movement ; and verify whether there are differences in the graphic representation of movement as an indicator of cognitive flexibility. The participants were N = 240 children aged 5–8 years; 1,440 drawings were (...) collected representing 2,880 characters from six stories. The analysis consisted: data quality control, using the kappa coefficient, and Generalizability Theory to test the instrument’s validity and reliability; Multivariate General Analysis and Mixed Linear Analysis of the factors ; Multivariate General Analysis of the graphic components: categories and microcategories, as well as the elements that make up the macrocategories: “Static,” “Indication,” and “Movement”; and calculation of the generalizability coefficient. The results show that: age best explains variability, with a high effect size across all components, thus increasing its complexity and at ages 6 and 7, “Indication” appears as a modulator of “Static” toward “Movement”. The generalizability coefficient is optimal. It is concluded that changes in the initial graphic representation of movement may interactively transform mental representation, thus increasing cognitive flexibility and prompting teaching applications to optimize such changes.

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.

In this paper, we argue that several recent ‘wide’ perspectives on cognition (embodied, embedded, extended, enactive, and distributed) are only partially relevant to the study of cognition. While these wide accounts override traditional methodological individualism, the study of cognition has already progressed beyond these proposed perspectives towards building integrated explanations of the mechanisms involved, including not only internal submechanisms but also interactions with others, groups, cognitive artifacts, and their environment. The claim is substantiated with reference to recent developments in (...) the study of “mindreading” and debates on emotions. We claim that the current practice in cognitive (neuro)science has undergone, in effect, a silent mechanistic revolution, and has turned from initial binary oppositions and abstract proposals towards the integration of wide perspectives with the rest of the cognitive (neuro)sciences.

In recent years, self-paced learning has attracted much attention due to its improvement to nonconvex optimization based machine learning algorithms. As a methodology introduced from human learning, SPL dynamically evaluates the learning difficulty of each sample and provides the weighted learning model against the negative effects from hard-learning samples. In this study, we proposed a cognitive driven SPL method, i.e., retrospective robust self-paced learning, which is inspired by the following two issues in human learning process: the misclassified samples are (...) more impressive in upcoming learning, and the model of the follow-up learning process based on large number of samples can be used to reduce the risk of poor generalization in initial learning phase. We simultaneously estimated the degrees of learning-difficulty and misclassified in each step of SPL and proposed a framework to construct multilevel SPL for improving the robustness of the initial learning phase of SPL. The proposed method can be viewed as a multilayer model and the output of the previous layer can guide constructing robust initialization model of the next layer. The experimental results show that the R2SPL outperforms the conventional self-paced learning models in classification task. (shrink)

Contemporary immunology has established its fundamental theory as a biological expression of personal identity, wherein the "immune self" is defended by the immune system. Protection of this agent putatively requires a cognitive capacity by which the self and the foreign are perceived and thereby discriminated; from such information, discernment of the environment is achieved and activation of pathways leading to an immune response may be initiated. This so-called cognitive paradigm embeds such functions as "perception," "recognition," "learning," and "memory" (...) to characterize immune processes, but the conceptual character of such functions has meanings that vary with the particular theory adopted. When different formulations of cognition are considered, immunology's conceptual infrastructure shifts: Extensions of conventional psychological understanding of representational cognition based on a subject-object dichotomy support notions of immune agency; alternatively, formulations of perception that dispense with representations and attendant notions of agency reconfigure the predicate epistemology dominating current immune theory. Reviewing immunological literature of the past five decades, these two understandings of perception – representational and non-representational – offer competing views of immune cognitive functions. These, in turn, provide competing philosophical understandings of immunology's conceptual foundations, which reflect parallel controversies dominating current debates in philosophy of mind and attendant discussions about personal identity.

Although debates continue, studies of cognition in infancy suggest that knowledge begins to emerge early in life and constitutes part of humans' innate endowment. Early-developing knowledge appears to be both domain-specific and task-specific, it appears to capture fundamental constraints on ecologically important classes of entities in the child's environment, and it appears to remain central to the commonsense knowledge systems of adults.

The aim of this article is to introduce the concept of Cognitive Fitness (CF), identify its key ingredients underpinning both real-time task performance and career longevity in high-risk occupations, and to canvas a holistic framework for their assessment, training, and augmentation. CF as a capacity to deploy neurocognitive resources, knowledge and skills to meet the demands of operational task performance, is likely to be multi-faceted and differentially malleable. A taxonomy of CF constructs derived from Cognitive Readiness (CR) and (...) Mental fitness (MF) literature maps into phases of operational cycles from foundational to advanced, mission-ready and recovery. Foundational cognitive attributes, such as attention, executive control and co-action, were hypothesized to be trainable at the initial Cognitive Gym phase. More advanced training targets at the CR phase included stress and arousal regulation, adaptability, teamwork, situation awareness (including detection, sense-making and prediction) and decision making (de-biasing and confidence calibration). The mission-ready training phase is focused on tolerances (to sleep loss, monotony, pain, frustration, uncertainty) and resistance (to distraction, deception or manipulation). Operational Augmentation phase relies on support tools such as decision aids and fatigue countermeasures, while the Recovery phase employs reflexive (e.g., mindfulness), and restorative practices (e.g., nutrition and sleep hygiene). The periodization of cognitive training in this cycle is hypothesized to optimize both real-time cognitive performance and the resilience that enables life-long thriving. One of the most promising avenues of validating this hypothesis is by developing an expert consensus on the key CF ingredients and their relative importance in high-performance settings. (shrink)

The question of the cognitive penetrability (CP) of experience is, roughly, the question whether cognitive states can influence, in some direct and non-trivial manner, one’s experiences. Whereas the CP of perception has recently been widely discussed by philosophers, the parallel question regarding pain has been utterly neglected. This chapter introduces the general notion of CP, as well as its epistemic import, focusing on visual experiences. It explains the notion of CP to pains, presenting some initial reasons to think (...) that pains are cognitively penetrable. CP is standardly understood as requiring an influence of cognitive states on both phenomenal character and representational content: it should be manifest in the way things appear to us both sensuously and representationally. The penetrating cognitive states influence cognitive states downstream of the perceptual experiences – notably, they affect judgments made on the basis of these experiences. (shrink)

Recent discussions of cognitive enhancement often note that drugs and technologies that improve cognitive performance may do so at the risk of “cheapening” our resulting cognitive achievements Arguing about bioethics, Routledge, London, 2012; Harris in Bioethics 25:102–111, 2011). While there are several possible responses to this worry, we will highlight what we take to be one of the most promising—one which draws on a recent strand of thinking in social and virtue epistemology to construct an integrationist defence (...) of cognitive enhancement.. According to such a line, there is—despite initial appearances to the contrary—no genuine tension between using enhancements to attain our goals and achieving these goals in a valuable way provided the relevant enhancement is appropriately integrated into the agent’s cognitive architecture. In this paper, however, we show that the kind of integration recommended by such views will likely come at a high cost. More specifically, we highlight a dilemma for users of pharmacological cognitive enhancement: they can meet the conditions for cognitive integration at the significant risk of dangerous dependency, or remain free of such dependency while foregoing integration and the valuable achievements that such integration enables. After motivating and clarifying the import of this dilemma, we offer recommendations for how future cognitive enhancement research may offer potential routes for navigating past it. (shrink)

This paper presents writing as an extended cognitive system comprised of brain, body, and the material form that is writing. Part I introduces the theoretical framework used for the analysis, Material Engagement Theory (MET), and the initial insights into writing systems gained by applying MET to Mesopotamian artifacts for numbers and writing. Part II discusses how writing as a material form has changed over time and why this material change reflects, accumulates, and distributes change in the behaviors and brains (...) of generations of writers. Part III explains why forms of writing used today are a visible form of language in being comprised of contrastive graphic features. Part IV argues against the idea that writing should be excluded from being considered as an extended cognitive system. On the contrary, considering writing from this perspective can provide new insights into the ways we use material forms—not just in writing but more broadly—to change our behaviors and brains, and their roles in intensifying and perpetuating those changes.

Andy Clark and David Chalmers claim that cognitive processes can and do extend outside the head.1 Call this the “hypothesis of extended cognition” (HEC). HEC has been strongly criticised by Fred Adams, Ken Aizawa and Robert Rupert.2 In this paper I argue for two claims. First, HEC is a harder target than Rupert, Adams and Aizawa have supposed. A widely-held view about the nature of the mind, functionalism—a view to which Rupert, Adams and Aizawa appear to subscribe— entails HEC. (...) Either HEC is true, or functionalism is false. The relationship between functionalism and HEC goes beyond support for the relatively uncontroversial claim that it is logically or nomologically possible for cognition to extend (the “can” part of HEC); functionalism entails that cognitive processes do extend in the actual world. Second, I argue that the version of HEC entailed by functionalism is more radical than the version that Clark and Chalmers suggest. I argue that it is so radical as to form a counterexample to functionalism. If functionalism is modified to prevent these consequences, then HEC falls victim to Rupert, Adams and Aizawa’s original criticism. An advocate of HEC has two choices: (1) accept functionalism and radical HEC; (2) give up HEC entirely. Clark and Chalmers’ intermediate position of a modest form of HEC is unsustainable. The argument of this paper, although initially appearing to support Clark and Chalmers, ultimately argues against their position. The price of HEC is rampant expansion of the mind into the world, and the implausibility of such expansion is indicative of deep-seated problems with functionalism. The argument of this paper consequently speaks to wider issues than just the status of HEC. The reasons for.. (shrink)

This article looks at some of the metaphysical properties of cognitive artefacts. It first identifies and demarcates the target domain by conceptualizing this class of artefacts as a functional kind. Building on the work of Beth Preston, a pluralist notion of functional kind is developed, one that includes artefacts with proper functions and system functions. Those with proper functions have a history of cultural selection, whereas those with system functions are improvised uses of initially non-cognitive artefacts. Having identified (...) the target domain, it then briefly looks at the multiple usability of physical structures and the multiple realizability of cognitive function. Further developing insights from the “dual nature of artefacts thesis”, the article ends with conceptualizing the structure–function relations of cognitive artefacts. More specifically, it unpacks the relation between physical structure, representational structure, information, and cognitive function. (shrink)

Observations of ultrafast cognition in human performance challenge intuitive information processing and computation metaphors of cognitive processing. Instances of ultrafast cognition are marked by ultrafast response times of reliable, accurate responses to a relatively complex stimulus. Ultrafast means response times that are as fast as a single feedforward burst of activity across the nervous system connecting eye to hand. Thus the information processing and computation metaphors in question are those in which some amount of time is required to decide (...) and initiate a response, over and above the minimum time required, physiologically, for the eye-hand chain of action potentials—these are metaphors in which the brain does work that has a measurable duration in time. Ultrafast cognition can be explained by synergies spanning the mind and body. Synergies are temporary dynamical structures that anticipate context-appropriate behaviour. An anticipatory state poises the mind and body in symmetry among equivalent options for behaviour, and only a minimal change in context, favouring one option over any other, is sufficient to break symmetry and enact an ultrafast cognitive response.

According to the popular Grounded Cognition Model (GCM), the sensory and motor features of concepts, including word meanings, are stored directly within neural systems for perception and action. More precisely, the core claim is that these concrete conceptual features reuse some of the same modality-specific representations that serve to categorize experiences involving the relevant kinds of objects and events. Research in semantic typology, however, has shown that word meanings vary significantly across the roughly 6500 languages in the world. I argue (...) that this crosslinguistic semantic diversity has significant yet previously unrecognized theoretical consequences for the GCM. In particular, to accommodate the typological data, the GCM must assume that the concrete features of word meanings are not merely stored within sensory/motor brain systems, but are represented there in ways that are, to a nontrivial degree, language-specific. Moreover, it must assume that these conceptual representations are also activated during the nonlinguistic processing of the relevant kinds of objects and events (e.g., during visual perception and action planning); otherwise, they would not really be grounded, which is to say, embedded inside sensory/motor systems. Crucially, however, such activations would constitute what is traditionally called linguistic relativity—that is, the influence of language-specific semantic structures on other forms of cognition. The overarching aim of this paper is to elaborate this argument more fully and explore its repercussions. To that end, I discuss in greater detail the key aspects of the GCM, the evidence for crosslinguistic semantic diversity, pertinent work on linguistic relativity, the central claim that the GCM entails linguistic relativity, some initial supporting results, and some important limitations and future directions.

It has been proposed that individuals with autism spectrum disorder struggle both with response initiation and with response inhibition, both of which are functions of the executive system. Experimental tasks are unlikely pure measures of a single cognitive domain, and in this study we aim at understanding the contributions of response initiation difficulties to possible deficits in inhibitory control in autism. A sample of adults diagnosed with ASD and a control sample participated in this study. To participants it was (...) asked to perform a sentence-completion task with two different condition: Part A—targeting response initiation and Part B—engaging inhibitory processes. Importantly, we have analyzed the B-A latencies that have been proposed for the removal of the response initiation confound effect. Results show that no differences between the groups were found in accuracy measures, either in Part A nor Part B. However, in both conditions autistic participants were significantly slower to respond than the group of participants with typical development. Critically, we show that when subtracting the response times of Part A from Part B no group differences attributable to inhibitory processes remained. With this study we corroborate the existence of difficulties with response initiation in autism and we question the existence of troubles in inhibition per se. (shrink)

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed (...) and implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

Knowledge is a social institution, a social activity, as well as the product of that social activity. All known societies incorporate several modes of hierarchical knowledge. Three styles of knowledge co-exist in the transitional societies of the third world in general and of contemporary Africa in particular (even though in each of the latter, only one style tends to predominate). The first are initiation societies - where power is conferred on the initiated; the second are learned societies (or academies) - (...) which handle science and technologies; and the third are industrial societies - whose enterprises apply the technologies in order to improve humankind’s material and cultural condition. The initiation, learned and industrial societies were developed in a pre-modern, pre-industrial context which was monarchic, sacred, anti-democratic or endowed with a tribal democracy. A gradual opening can be seen in the passage of initiation societies (where power is the perquisite of the initiated) towards learned societies and then, later, to industrial ones. Here, the problem is knowing whether and how to bring into play a fourth style of society - cognitive society - which requires relatively advanced conditions of democracy. (shrink)

AimTo evaluate the cognitive functioning of subjects practicing trance mediumship in Brazil.MethodThe study was based on the measurement of cognitive functions of 19 spirits mediums through neuropsychological tests such as the Brief Cognitive Screening Battery, the Verbal Fluency Test, the digit span test, the cube test, the five digit test and an evaluation of mental health through scales such as the Beck Depression Inventory, the Self-Report Questionnaire, and the Trauma History Questionnaire. The sample included the participation of (...) spirit mediums divided into two groups. The more experienced group with 11 subjects had more than 10 years of mediumistic practice, while the other less experienced group with 8 subjects had 1–5 years of experience. The inclusion criteria were psychophonic mediums with regular trance practices for at least one year. The data collected were analyzed using the SPSS statistical package.ResultsRegarding performance on the BCSB and digit span test, all subjects reached scores at the median or higher in comparison to standardized scores of Brazilians. Scores of 90% on the cube test and 42% on the FAS were reached in comparison to median or higher values, versus the median of standardized scores among Brazilians. On the FDT, we found statistical significance in the choice stage, with higher performance of subjects whose initial age of trance recognition occurred before 21 years old. On the BDI scale, no participant met the criteria for major depression. The SRQ showed an incidence of common mental disorders in 21% of the sample, which was more prevalent in the LEG.ConclusionThe cognitive functioning of subjects who practice trance mediumship in Brazil is associated with cognitive health. Executive dysfunction may be a tendency in LEG. However, an incidence of common mental disorders in the LEG was observed. Executive processing was higher in the subgroup with early practices of recognizing the phenomenon. (shrink)

We do not all make choices, reason, interpret our experience, or respond to our environment in the same way. A recent surge of scientific interest has thrust these individual differences into the spotlight: researchers in cognitive psychology and neuroscience are now devoting increasing attention to cognitive variation. The philosophical dimensions of this research, however, have yet to be systematically explored. Here I make an initial foray by considering how cognitive variation is characterized. I present a central dilemma (...) facing descriptions of individual differences, discuss several distinctions used to categorize variation, and show that these distinctions require further elaboration. Finally, by canvassing several philosophical topics for which the characterization of cognitive variation may have significant implications, I argue that philosophers should take note of how and why our minds differ.

In lieu of an abstract, here is a brief excerpt of the content:484 BOOK REVIEWS faith. Yet faith-knowledge alone is insufficient to account for Jesus' extraordinary gifts as a teacher: for this we must appeal to a special charism along the lines of an infused knowledge. According to Torrell this knowledge is best understood by reference to Aquinas's mature teaching on prophecy: God equipped the prophets with an infused light (but not infused ideas) enabling them to communicate divine truths to (...) others. Likewise, God conferred on Jesus an infused light akin to that of the prophets, but with this qualitative difference: in him the lumen is a permanent feature of his cognitive life (a habitus), while it is given to the prophets only intermittently (per modum actus). The foregoing i;ummary will have served its purpose if it has conveyed to the reader some sense of the very rich historical, philosophical, and theological reflections that comprise this volume. The editorial team of the Revue thomiste is to be commended for the high caliber of this and the other special publications it has produced in recent years: the 1992 commemorative volume on the theological achievement of M.-M. Labourdette; th~ 1993 centenary index ("tables generales 1893-1992"); the Gilson issue of 1994; and most recently an issue devoted to Thomas Aquinas and the onto-theo-logy debate (1995).

Aquinas insists that the creator's primary intent is the "order of the universe," and Bernard Lonergan's dissertation on "operating grace" in Aquinas's writings managed to move beyond the stalemated discussion of "sufficient" and "efficacious" grace precisely because he displayed how any discourse about grace had to be connected with larger theorems of the creator's operation in creation. What speaking of the divine action called "grace" requires is a set of metaphysical skills adequate to speaking of the "order of the universe" as created. A tall order, whose scope the published edition of his dissertation-Grace and Freedom-so understated that its implications have been missed by many philosophers and theologians fascinated with such questions. Stebbins's careful reconstruction of that text reminds us of its daunting scope. And part of the reason it can do so is that he illustrates both the method and conclusions of Grace and Freedom through a later text which Lonergan had composed (in Latin) for a course on grace offered from 1947 to 1960: De ente supernaturali (which will appear in volume 16 [Early Latin Theology] of the Collected Works of Bernard Lonergan, published by BOOK REVIEWS 485 University of Toronto Press). The significance of this collateral source is that it can profit from and respond to Henri de Lubac's epochal Surnaturel (1946). For those not familiar with Grace and Freedom, as well as some who thought they were, a list of Stebbins's chapters manages to convey the scope of Lonergan's achievement: 1. The Role of Understanding in Theological Speculation; 2. The Principal Instance of Supernatural Being: The Created Communication of the Divine Nature; 3. Thirteenth-Century Breakthrough (The "Theorem" of the Supernatural); 4. Supernatural Transformation of Human Activity; 5. Obediential Potency and the Natural Desire to See God; 6. Molinist and Bannezian Systems; 7. Theoretical Perspective on Divine Concourse; 8. Contingence, Sin and Divine Efficacy. As always, Lonergan must actively reflect on method while executing a theological inquiry, so Stebbins rightly begins with his insistence that such inquiry must be more than "just a networks of concepts; it is primarily an act of understanding" (xix)-Chapter 1. Then, following the expository order of De ente supematurali, he shows how Lonergan roots the supernatural in the theorems developed to speak of the natural: of creation itself. ("Theorem," as we shall see, is a favorite word of Lonergan's, intimating what it takes to move beyond our imaginations to a set of propositions able to articulate the metaphysical issues at stake.) Following the analogy of nature, we can see how the "two operations by which creatures... (shrink)

It is widely believed that what distinguishes the social cognition of humans from that of other animals is the belief–desire psychology of four–year–old children and adults (so–called theory of mind). We argue here that this is actually the second ontogenetic step in uniquely human social cognition. The first step is one year old children's understanding of persons as intentional agents, which enables skills of cultural learning and shared intentionality. This initial step is ‘the real thing’ in the sense that it (...) enables young children to participate in cultural activities using shared, perspectival symbols with a conventional/normative/reflective dimension—for example, linguistic communication and pretend play—thus inaugurating children's understanding of things mental. Understanding beliefs and participating in collective intentionality at four years of age—enabling the comprehension of such things as money and marriage—results from several years of engagement with other persons in perspective–shifting and reflective discourse containing propositional attitude constructions.

Cognitive agents form beliefs representing the world, evaluate the world as represented, form plans for making the world more to their liking, and perform actions executing the plans. Then the cycle repeats. This is the doxastic-conative loop, diagrammed in figure one.1 Both human beings and the autonomous rational agents envisaged in AI are cognitive agents in this sense. The cognition of a cognitive agent can be subdivided into two parts. Epistemic cognition is that kind of cognition responsible (...) for producing and maintaining beliefs. Practical cognition evaluates the world, adopts plans, and initiates action. There is a massive literature both in philosophy and artificial intelligence concerning various aspects of epistemic cognition, and large parts of it are well understood. Practical cognition is less well understood. We can usefully divide practical cognition into five parts: (1) the evaluation of the world as represented by the agent’s beliefs, (2) the adoption of goals for changing it, (3) the construction of plans for achieving goals, (4) the adoption of plans, and (5) the execution of plans. There is a substantial literature in AI concerning the construction and execution of plans, and I will say nothing further about those topics here. This paper will focus on the evaluative aspects of practical cognition. Evaluation plays an essential role in both goal selection and plan adoption. My concern here is the investigation of evaluation as a cognitive enterprise performed by cognitive agents. I am interested both in how it is performed in human beings and how it might be performed in artificial rational agents. (shrink)

In recent decades cognitive science has revolutionised our understanding of the workings of the human mind. Philosophy has made a major contribution to cognitive science and has itself been hugely influenced by its development. This dynamic book explores the philosophical significance of cognitive science and examines the central debates that have enlivened its history. In a wide-ranging and comprehensive account of the topic, philosopher M.J. Cain discusses the historical origins of cognitive science and its philosophical underpinnings; (...) the nature and role of representations in cognition; the architecture of the mind and the modularity thesis; the nature of concepts; knowledge of language and its acquisition; perception; and the relationship between the brain and cognition. Cain draws upon an extensive knowledge of empirical developments and their philosophical interpretation. He argues that although the field has generated some challenging new views in recent years, many of the core ideas that initiated its birth are still to be taken seriously. Clearly written and incisively argued, The Philosophy of Cognitive Science will appeal to any student or researcher interested in the workings of the mind. (shrink)

The field of cognitive modeling has progressed beyond modeling cognition in the context of simple laboratory tasks and begun to attack the problem of modeling it in more complex, realistic environments, such as those studied by researchers in the field of human factors. The problems that the cognitive modeling community is tackling focus on modeling certain problems of communication and control that arise when integrating with the external environment factors such as implicit and explicit knowledge, emotion, cognition, and (...) the cognitive system. These problems must be solved in order to produce integrated cognitive models of moderately complex tasks. Architectures of cognition in these tasks focus on the control of a central system, which includes control of the central processor itself, initiation of functional processes, such as visual search and memory retrieval, and harvesting the results of these functional processes. Because the control of the central system is conceptually different from the internal control required by individual functional processes, a complete architecture of cognition must incorporate two types of theories of control: Type 1 theories of the structure, functionality, and operation of the controller, and type 2 theories of the internal control of functional processes, including how and what they communicate to the controller. This book presents the current state of the art for both types of theories, as well as contrasts among current approaches to human-performance models. It will be an important resource for professional and student researchers in cognitive science, cognitive-engineering, and human-factors.Contributors: Kevin A. Gluck, Jerry T. Ball, Michael A.

Although machine intelligence is increasingly employed in healthcare, the realm of decision-making in medical ethics remains largely unexplored from a technical perspective. We propose an approach based on fuzzy cognitive maps (FCMs), which builds on Beauchamp and Childress’ prima-facie principles. The FCM’s weights are optimized using a genetic algorithm to provide recommendations regarding the initiation, continuation, or withdrawal of medical treatment. The resulting model approximates the answers provided by our team of medical ethicists fairly well and offers a high (...) degree of interpretability. Possible applications of such a system include informal guidance on medical ethics dilemmas as well as educational purposes. (shrink)

An initial distinction is made between two ways of referring in thought to a particular object. One can think of an object in virtue of having a descriptive condition in mind which uniquely denotes that object. Alternatively, one can think about a particular in a more direct way. It is with the nature of this more direct sort of reference that the subsequent discussion is primarily concerned. ;It has been argued that the relation of direct reference is purely causal in (...) nature. A number of difficulties are raised for this causal view. A diagnosis of these difficulties suggests that the causal view ignores the cognitive aspects of direct reference. ;The idea that direct reference is a cognitive relation is not new. Bertrand Russell's notion of knowledge by acquaintance can be thought of as involving the idea of a relation of reference which is direct and cognitive. A good place to begin an exploration of the cognitive dimensions of direct reference is with Russell's notion of acquaintance. Thus this notion is analysed in some depth. ;An objection to the effect that acquaintance is a relation incapable in principle of playing a role in an account of reference is shown to be unfounded. This clears the way for an extended discussion of the nature of acquaintance. This discussion suggests that we should posit a special demonstrative way in which objects can be presented to us. This demonstrative way of being presented with an object is in turn explored by way of an extended metaphor, in which it is suggested that becoming acquainted with an object should be thought of as the opening of a mental file of a special sort for that object. ;Some indirect support for this account of demonstrative modes of presentation and the associated account of direct reference comes from the fact that these notions can help solve the problem of cognitive significance that has been thought to pose a serious threat to theories that somehow treat reference as direct. ;Finally, some potential counterexamples are examined and shown not to seriously threaten the acquaintance theory of direct reference.

This is a review of the book Mozg - kultura - socium. Kantianskaya programma v cognitivnykh issledovaniyakh by Bazhanov V.A. The author`s main aim is a reconsideration of some fundamental principles of epistemology and philosophy of science in the light of state-of-the-art advancements of neurosciences. According to the author of the book, social and cultural revolution in neurosciences has been crucially modifying the initial Kantian program of consciousness research and the modes of linguistic representation of its results. In particular, in (...) epistemology the universal concept of transcendental subject has been altered with regard to neurobiological and social data, which concern some preconditions of cognitive activity. In philosophy of science such a shift of research perspective allows to implement a naturalistic interpretation of natural sciences, clarifies the problem of empirical foundations of mathematics and sheds a new light on the problem of apriori elements of mathematical thought. The analysis of evolutionary and neurobiological preconditions of logical thought leads to the sort of revival of psychologism program in logic, which enables author to put forward an original interpretation of the problem of plurality of logical systems. Finally, some topics of social sciences as well as problems of genesis of art, ethical and religious systems, can acquire new interpretation with respect to modern investigations in cognitive science.

ABSTRACTHumans are cognitive misers because their basic tendency is to default to processing mechanisms of low computational expense. Such a tendency leads to suboptimal outcomes in certain types of hostile environments. The theoretical inferences made from correct and incorrect responding on heuristics and biases tasks have been overly simplified, however. The framework developed here traces the complexities inherent in these tasks by identifying five processing states that are possible in most heuristics and biases tasks. The framework also identifies three (...) possible processing defects: inadequately learned mindware; failure to detect the necessity of overriding the miserly response; and failure to sustain the override process once initiated. An important insight gained from using the framework is that degree of mindware instantiation is strongly related to the probability of successful detection and override. Thus, errors on such tasks cannot be unambiguously attributed to miserly processing – and corre... (shrink)

A current and very influential theory in psychology holds that infants have innate, perceptually informed systems that endow them with surprisingly high-level concepts—for example, concepts of cardinality and causality. Proponents of core cognition hold that these initial concepts then provide the building blocks for later adult ideas within these domains. This paper reviews the evidence for core cognition and argues that these systems aren’t sufficient to explain how children learn their way to adult thoughts about language, number, or cause.
