To function well in an unpredictable environment using unreliable components, a system must have a high degree of robustness. Robustness is fundamental to biological systems and is an objective in the design of engineered systems such as airplane engines and buildings. Cognitive systems, like biological and engineered systems, exist within variable environments. This raises the question, how do cognitive systems achieve similarly high degrees of robustness? The aim of this study was to identify a set of mechanisms that enhance robustness (...) in cognitive systems. We identify three mechanisms that enhance robustness in biological and engineered systems: system control, redundancy, and adaptability. After surveying the psychological literature for evidence of these mechanisms, we provide simulations illustrating how each contributes to robust cognition in a different psychological domain: psychomotor vigilance, semantic memory, and strategy selection. These simulations highlight features of a mathematical approach for quantifying robustness, and they provide concrete examples of mechanisms for robust cognition. (shrink)

The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and training is rare. Computational modeling can provide the crucial link between a century of accumulated experimental data on the spacing effect and the emerging interest in using that research to enable adaptive instruction. In this paper, we review relevant literature and identify 10 criteria for rigorously (...) evaluating computational models of the spacing effect. Five relate to evaluating the theoretic adequacy of a model, and five relate to evaluating its application potential. We use these criteria to evaluate a novel computational model of the spacing effect called the Predictive Performance Equation. Predictive Performance Equation combines elements of earlier models of learning and memory including the General Performance Equation, Adaptive Control of Thought—Rational, and the New Theory of Disuse, giving rise to a novel computational account of the spacing effect that performs favorably across the complete sets of theoretic and applied criteria. We implemented two other previously published computational models of the spacing effect and compare them to PPE using the theoretic and applied criteria as guides. (shrink)

A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive architecture, leveraging (...) the strengths from each to develop a more comprehensive explanation. The integration of these methodologies is used to account for changes in human performance on a sustained attention task across 88 h of total sleep deprivation. The integrated model captures changes due to time awake and circadian rhythms, and it also provides an account for underlying changes in the cognitive processes that give rise to those effects. The results show the potential for developing mechanistic accounts of how fatigue impacts cognition, and they illustrate the increased explanatory power that is possible by combining theoretical insights from multiple methodologies.

Successfully explaining and replicating the complexity and generality of human and animal learning will require the integration of a variety of learning mechanisms. Here, we introduce a computational model which integrates associative learning (AL) and reinforcement learning (RL). We contrast the integrated model with standalone AL and RL models in three simulation studies. First, a synthetic grid‐navigation task is employed to highlight performance advantages for the integrated model in an environment where the reward structure is both diverse and dynamic. The (...) second and third simulations contrast the performances of the three models in behavioral experiments, demonstrating advantages for the integrated model in accounting for behavioral data.

This article examines five different Medical-Legal Partnerships associated with Yale Law School in New Haven, Connecticut to illustrate how MLP addresses the social determinants of poor health. These MLPs address varied and distinct health and legal needs of unique patient populations, including: 1) children; 2) immigrants; 3) formerly incarcerated individuals; 4) patients with cancer in palliative care; and 5) veterans. The article charts a research agenda to create the evidence base for quality and evaluation metrics, capacity building, sustainability, and best (...) practices; it also focuses specifically on a research agenda that identifies the value of the lawyers in MLP. Such a focus on the “L” has been lacking and is overdue. (shrink)

The discovery and ongoing investigation of microRNAs suggest important conceptual and methodological lessons for philosophers and historians of biology. This paper provides an account of miRNA research and the shift from viewing these tiny regulatory entities as minor curiosities to seeing them as major players in the post-transcriptional regulation of genes. Conceptually, the study of miRNAs is part of a broader change in understandings of genetic regulation, in which simple switch-like mechanisms were reinterpreted as aspects of complex cellular and genome-wide (...) processes. Among them are the activities of small RNAs, previously regarded as non-functional. Methodologically, the miRNA story suggests new ways of characterizing biological research that should prove helpful to philosophers of science who seek to develop more pluralistic, pragmatic models of scientific inquiry. miRNA research displays iterative movements between multiple modes of investigation that include not only the proposal and testing of hypotheses but also exploratory, technology-oriented and question-driven modes of research. As an exemplary story of scientific discovery and development, the miRNA case illustrates transitions from genetics to genomics and systems biology, and it shows how diverse configurations of research practice are related to major scientific advances.

Two putative functions of emotion experience ? its roles in intentional action and in social understanding ? were investigated using a group of individuals (repressors) known to have impaired anxiety experience. Repressors, low-anxious, high-anxious, and defensive high-anxious individuals were asked to give a public presentation, and then given the opportunity to avoid the presentation. Repressors were the group most likely to avoid giving the presentation, but were the least likely to give an emotional explanation for their avoidance. By contrast, they (...) were not less likely than other groups to provide negative emotional explanations of another person?s behaviour in a film clip. We concluded that: (1) repressors are impaired in self- but not in other-explanation using emotion, implying that ?simulation? is not the method used by repressors to ground their folk psychology, (2) the intentional avoidance shown by repressors is indicative of some intact first-order phenomenal anxiety experience but that they lack second-order awareness of this anxiety experience.

In some areas of cognitive science we are confronted with ultrafast cognition, exquisite context sensitivity, and scale-free variation in measured cognitive activities. To move forward, we suggest a need to embrace this complexity, equipping cognitive science with tools and concepts used in the study of complex dynamical systems. The science of movement coordination has benefited already from this change, successfully circumventing analogous paradoxes by treating human activities as phenomena of self-organization. Therein, action and cognition are seen to be emergent in (...) ultrafast symmetry breaking across the brain and body; exquisitely constituted of the otherwise trivial details of history, context, and environment; and exhibiting the characteristic scale-free signature of self-organization.

As prototypical incentive with biological meaning, food illustrates the distinction between money as tool and money as drug. However, consistent neuroscience results challenge this view of food as intrinsic value and opposite to drugs of abuse. The scarce availability over evolutionary time of both food and money may explain their similar drug-like non-satiability, suggesting an integrated mechanism for generalized reinforcers.

Characterizing how activity in the central and autonomic nervous systems corresponds to distinct emotional states is one of the central goals of affective neuroscience. Despite the ease with which individuals label their own experiences, identifying specific autonomic and neural markers of emotions remains a challenge. Here we explore how multivariate pattern classification approaches offer an advantageous framework for identifying emotion-specific biomarkers and for testing predictions of theoretical models of emotion. Based on initial studies using multivariate pattern classification, we suggest that (...) central and autonomic nervous system activity can be reliably decoded into distinct emotional states. Finally, we consider future directions in applying pattern classification to understand the nature of emotion in the nervous system. (shrink)

In 1864 - two years before the publication of The Communist Manifesto and 21 years before the publication of Das Kapital - Karl Marx published an essay titled Peuchet on Suicide. The essay was originally presented as a translation of excerpts from the memoirs of Jacques Peuchet, a leading French police administrator, economist and statistician. Plaut and Anderson reveal that Marx's Peuchet on Suicide is not a straightforward translation, but is an edited version in which Marx adds passages of his (...) own, altering the emphasis of the text from a moral and psychological focus to a profoundly social one. Thus, the essay very strongly reflects Marx's own position on this controversial subject. Sociologist Kevin Anderson provides an extensive introduction situating the essay in the context of Marx's work, especially that on gender; Plaut's essay focuses on the psychological aspects of the work, in particular contrasting Marx's thoughts on suicide with those of Freud and Durkheim.

Over the past decade, scores of articles have been published debating whether and when it is ethical for physicians to refuse requests from patients for legal, professionally permitted interventions. Numerous voices have condemned "conscientious refusals" for obstructing patients' access to needed and "standard" health-care services, for imposing physicians' personal ideologies on patients, and for contradicting physicians' professional ethical obligations. Conversely, other voices argue that conscientious refusals are essential for maintaining the integrity of clinicians as moral agents, for assuring the renown (...) of the broader medical profession, and for preventing the imposition of moral viewpoints onto minorities...

This paper focuses on how African national leaders can make global democracy relevant to sustainable development in Africa. Seeing the problem of sustainable development in Africa from the structural and functional angles, this paper begins with an introduction and a clarification of terms such as ‘democracy’, ‘globalization’ and ‘development’. It then analyzes the underlying foundations of global democracy and its implications to cultures of the African peoples. This paper tries to place the impact of global democracy on Africa in perspectives (...) by weighing the pros and cons of global democracy. Tracing the genesis of functional and developmental problems in the post-colonial Africa to structural problems occasioned by Africa’s colonial experience, this paper however strongly contends that the main problem militating against sustainable development in the post-colonial Africa is bad politics and mismanagement of national resources. African peoples need to be taught that some of the African national leaders are responsible for the bad condition of underdevelopment in the global period because of bad political governance ranging from the inability of African leaders to calculate all the relevant factors in the making of their policies as well as failing to provide effective technologies and competent staff to deal with rigging of elections and other electoral problems in addition to corruption and mismanagement of public funds. There is no way for the African nations to survive without production of goods and services in terms of farming, agriculture and diversification of their revenue base. National leaders of the various African nations cannot avoid policies that enable the industrialization of African nations through the provision of the basic infrastructures and viable amenities for social, economic, and political development. They should however be wary of debt traps of International Monetary Fund and World Bank because borrowing nations are often given difficult conditions that often make it difficult for them to obtain the desired benefits in terms of sustainable development. The study recommends that for sustainable development to take place in Africa there is need for national leaders to embrace good political governance that places the people at the centre of development to be manifested in guileless electoral process and effective management of the resources. This paper contends that the realization of sustainable development in African nations requires moral, political, and economic integration. It concludes with perspectives for further research on the issue. (shrink)

Specialists and primary care physicians play an integral role in treating the twin epidemics of pain and addiction. But inadequate access to specialists causes much of the treatment burden to fall on primary physicians. This article chronicles the differences between treatment contexts for both pain and addiction — in the specialty and primary care contexts — and derives a series of reforms that would empower primary care physicians and better leverage specialists.

Husserl seems to have devoted roughly equal amounts of energy and pages to the description of perception, judgement, and imagination. By “description,” he meant the analysis of the traits and components of mental states or acts and their objects. As his views changed over the years about the nature of intentionality and philosophy, the descriptive psychology of the Logical Investigations (1900/01) gave way to descriptive programmes in which the objects of perception and of judgement were conceived of in terms of (...) a new, analytic framework; in particular Husserl lost interest in describing the things and processes in the real world that are the objects of perception and judgement and so too in describing their relations to these acts. His new analytic framework, particularly as it applies to perception, has been thoroughly expounded and discussed in the literature. My aim here is to expound Husserl's first descriptions of perception within the framework of the Investigations and to incorporate as far as possible his later descriptive results to the extent that these are separable from his later turn to idealism.

The tutelage of our mentors as scientists included the analogy that writing a good scientific paper was an exercise in storytelling that omitted unessential details that did not move the story forward or that detracted from the overall message. However, the advice to not get lost in the details had an important flaw. In science, it is the many details of the data themselves and the methods used to generate and analyze them that give conclusions their probative meaning. Facts may (...) sometimes slow or distract from the clarity, tidiness, intrigue, or flow of the narrative, but nevertheless they are important for the assessment of what was done, the trustworthiness of the science, and the meaning of the findings. Nevertheless, many critical elements and facts about research studies may be omitted from the narrative and become hidden from scholarly scrutiny. We describe a “baker’s dozen” shortfalls in which such elements that are pertinent to evaluating the validity of scientific studies are sometimes hidden in reports of the work. Such shortfalls may be intentional or unintentional or lie somewhere in between. Additionally, shortfalls may occur at the level of the individual or an institution or of the entire system itself. We conclude by proposing countermeasures to these shortfalls. (shrink)

People coordinate body postures and gaze patterns during conversation. We review literature showing that (1) action embodies cognition, (2) postural coordination emerges spontaneously when two people converse, (3) gaze patterns influence postural coordination, (4) gaze coordination is a function of common ground knowledge and visual information that conversants believe they share, and (5) gaze coordination is causally related to mutual understanding. We then consider how coordination, generally, can be understood as temporarily coupled neuromuscular components that function as a collective unit (...) known as a coordinative structure in the motor control literature. We speculate that the coordination of gaze and body sway found in conversation may be understood as a cross‐person coordinative structure that embodies the goals of the joint action system. (shrink)

A summary of Russell’s logical atomism, understood to include both a metaphysical view and a certain methodology for doing philosophy. The metaphysical view amounts to the claim that the world consists of a plurality of independently existing things exhibiting qualities and standing in relations. The methodological view recommends a process of analysis, whereby one attempts to define or reconstruct more complex notions or vocabularies in terms of simpler ones. The origins of this theory, and its influence and reception are also (...) discussed. (shrink)

Public reason liberals typically defend an accessibility requirement for reasons offered in public political dialog. The accessibility requirement holds that public reasons must be amenable to criticism, evaluable by reasonable persons, and the like. Public reason liberals are therefore hostile to the public use of reasons that appear inaccessible, especially religious reasons. This hostility has provoked strong reactions from public reason liberalism's religion-friendly critics. But public reason liberals and their religion-friendly critics need not be at odds because the accessibility requirement (...) is implausible. In fact, the accessibility requirement is ambiguous between two interpretations, one of which is too stringent and the other too loose. Depending upon the interpretation, accessibility either restricts the use of too many secular reasons or permits appeal to a wide range of religious reasons. The accessibility requirement should therefore be rejected. (shrink)

This essay explores the adventures of the word “without” in Jacques Derrida's work from the mid-1970s until his death. It is argued that Derrida comes to Yale primarily with a new reading of Kantian formalism in mind and that this in part explains both the ready acceptance and the resistance he found at Yale. It is further argued that by the time Derrida left Yale in the mid-1980s, the word “without” was serving a new end: ethics and religion. And yet (...) Derrida remained Kantian in his main emphases.

Phenomenology was in large part the discovery of Edmund Husserl, whose Logical Investigations of 1900/01 are normally regarded as the work that launched the phenomenological movement. Yet Husserl's phenomenology, in particular in the form in which it is set out in this his most important contribution to philosophy, is itself part of an Austrian philosophical tradi tion inspired by Brentano and continued, in very different ways, by Meinong, Stumpf, Twardowski, Ehrenfels, Husserl - and Marty. Like Brentano and all his heirs (...) Marty's philosophical interests were in the philosophy of mind, where this is taken to include or at least ground the philosophy of language, and analytic metaphysics. It is Marty's discussions of topics in these two areas that provide the contributions to this volume with their subject-matter. The papers by Roderick Chisholm, S. -Y.

Most of the experiments described are drawn from the author’s personal experience over the last 15 years. (shrink)

In recent years, many scholars have suggested that the Baldwin effect may play an important role in the evolution of language. However, the Baldwin effect is a multifaceted and controversial process and the assessment of its connection with language is difficult without a formal model. This paper provides a first step in this direction. We examine a game-theoretic model of the interaction between plasticity and evolution in the context of a simple language game. Additionally, we describe three distinct aspects of (...) the Baldwin effect: the Simpson– Baldwin effect, the Baldwin expediting effect and the Baldwin optimizing effect. We find that a simple model of the evolution of language lends theoretical plausibility to the existence of the Simpson– Baldwin and the Baldwin optimizing effects in this arena, but not the Baldwin expediting effect.

Does “community” contain an ineradicable memory of “communion,” and thereby inevitably have conceptual ties to Christianity, if not to fascism? Or can the word, rather, indicate a new way of being in common, one that became briefly visible in the communist experiment, understood first as the appearing of the truth of democracy before it collapsed under the weight of ideology and militarism? While Jean-Luc Nancy identifies motifs from Maurice Blanchot’s early right-wing political commitments in his later left-wing thought, this essay (...) addresses and critiques another of Nancy’s claims: that despite Blanchot’s affirmation of a community unregulated by a reference to unity, he is, in fact, committed to the Christian notion of communion. However, Blanchot distanced his notion of inter-subjectivity from any conception of God, proposing, instead, a “dissymmetric” rather than asymmetric relation, grounded in the encounter of the Other’s death rather than in some trace of the divine.

This study provides a comparison of thinking style and ethical decision-making patterns between 386 U.S. students and 506 students from the People’s Republic of China enrolled in undergraduate business education in their respective countries. Contrary to our expectations, the Chinese students demonstrated a significantly greater linear thinking style compared to American students. As hypothesized, both Chinese and U.S. students possessing a balanced linear and nonlinear thinking style profile demonstrated greater ethical intent across a series of ethics vignettes. Chinese students also (...) were more likely to adopt an act utilitarian rationale, an ethical philosophy that in practice may violate government regulations or social rules to benefit one’s family instead of society for explaining their decisions across the vignettes. We conclude with a discussion of important theoretical as well as practical and potential future implications based on this comparative study. (shrink)

In his review of Eddie Glaude's Exodus! “Politics, Racial Solidarity, Exodus!” Robert Gooding-Williams argues that, despite sympathizing with Glaude's conception of racial solidarity, he finds that “Glaude's approach to racial solidarity is not pragmatic enough, precisely because the myth of the essential black subject still haunts it, its claims to the contrary notwithstanding.” This article challenges Gooding-Williams's reading of Exodus!, demonstrating that despite his grasp of Glaude's conceptual map, he misses precisely what is at stake for Glaude's pragmatic notion of (...) racial solidarity. Understanding what is at stake for Glaude's conception of racial solidarity, one sees how the subtlety of his pragmatism actually resists any lingering essentialism. However, this article concludes by showing that despite Glaude's evasion of Gooding-Williams's charge, it is his emphasis on the Deweyan language of “problem solving” that courts the criticism in the first place. To circumvent the potential for misunderstanding, this article emphasizes a “negotiation of social practices” as an alternative to Glaude's emphasis on the language of “problem solving activity.”.

Most research on metaphors that construe time as motion (motion metaphors of time) has focused on the question of whether it is the times or the person experiencing them (ego) that moves. This paper focuses on the equally important distinction between metaphors that locate times relative to ego (the ego-based metaphors Moving Ego and Moving Time) and a metaphor that locates times relative to other times (sequence is relative position on a path). Rather than a single abstract target domain TIME, (...) these two kinds of temporal metaphor metaphorize different kinds of temporal concept—perspective-specific vs. perspective-neutral temporal concepts. Recognition of this distinction enhances the explanatory potential of conceptual metaphor theory (Lakoff and Johnson 1980). An example involves the interaction of deixis and the temporal reference crosslinguistically of vocabulary with the spatial meanings in-front and behind. More generally, this approach refines our ability to describe the temporal concepts involved in motion metaphors of time. Such temporal concepts are present not only in the target domains, but also in the source domains of motion metaphors of time, where we find space-to-time metonymy, which may play a role in motivating the metaphors. In order to distinguish such metonymy from metaphor, we need to characterize metaphor as a mapping across frames rather than domains. (shrink)

Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically has addressed this question using limited human data that are restricted to semantic similarity and/or general semantic relatedness. We tested eight DSMs that are popular in current cognitive and psycholinguistic research (positive pointwise mutual information; global vectors; and three variations each of Skip-gram and continuous bag of words (CBOW) (...) using word, context, and mean embeddings) on a theoretically motivated, rich set of semantic relations involving words from multiple syntactic classes and spanning the abstract–concrete continuum (19 sets of ratings). We found that, overall, the DSMs are best at capturing overall semantic similarity and also can capture verb–noun thematic role relations and noun–noun event-based relations that play important roles in sentence comprehension. Interestingly, Skip-gram and CBOW performed the best in terms of capturing similarity, whereas GloVe dominated the thematic role and event-based relations. We discuss the theoretical and practical implications of our results, make recommendations for users of these models, and demonstrate significant differences in model performance on event-based relations.

Critical pedagogy is an optimistic approach for achieving transformative agency, which remains an elusive and vital aspect of civic education. Therefore, the purpose of this study was to examine the pedagogical approach of three critically identifying teachers. Specifically, this study was interested in understanding participant teacher critically civic ontological postures. The posture implies an understanding of the power inherent to civic relation and pedagogy. Participant teachers uniquely demonstrated postures that allowed them to address conceptual, personal, and material aspects of civics (...) education. Participants achieved this first by making clear temporal connections between citizenship and disciplines; second, by incorporating student experiences; and lastly by utilizing a range of instructional approaches to negate traditional civic archetypes. Findings suggest that critical civic ontological postures are dynamic, contextual, and disciplinarily situated. Authentically critically civic ontological postures include developing intellectual solidarity with students and those in educational communities. (shrink)

Traditional critical thinking courses introduce students to tools for analyzing and evaluating arguments and reasoning. There are, however, good reasons to think that those courses fail to motivate students to make full use of those tools. It is this motivational problem that is the focus of the present paper.

I offer a three-step strategy for challenging students’ presumption of competency regarding critical thinking, thereby (...) motivating them to embrace the tools we offer.

We tend to imagine revolution as a vivid tableau of uprisings and armed conflicts. Much less notice is taken of the complex layers of meaning that shape our understanding of these events: why some are seen as just expressions of a popular will, while others are condemned as wild disruptions of political order. A critical understanding of politics must grapple with these subtle, often unnoticed normative issues. This essay tries to understand some of the processes that create political normativity, investigating (...) the way revolutionary movements use time to endow themselves with normative value. I sketch a genealogy of revolution across three centuries, noting changes in its meaning, observing the rise of discourse as an important mode of revolutionary activity, and tracing a shifting mosaic of temporalities that are politicized in important ways. Time is instrumentalized to justify political insurgency in this history. Time, in short, becomes a tool of revolution. (shrink)

This response raises two critical questions about Nico Stehr's article 'Knowledge, Markets and Biotechnology.' First, it examines his claim that in a 'knowledge society' consumers now base their decisions about purchases on more intangible criteria than a product's utility. We demonstrate that this is not unique to a 'knowledge society.' For more than a century Western consumers have been enmeshed in markets where advertisers aim to fashion consumer desires for products by employing strategies that appeal to anything but a product's (...) 'use value.' Second, we address Stehr's claim that in a market undergoing a process of 'moralization,' decisions about consumption occur in a context of epistemological uncertainty caused by proliferating and contradictory information. We propose that such a situation of radical uncertainty in decision-making is not unique to the marketplace, but reflects how most individuals must now relate to almost all scientific claims. The propagation of contested knowledges about any number of scientific truths - which are themselves largely unverifiable by laypeople - means that most individuals must rely on assorted social and cultural considerations when aligning themselves with any scientific knowledge.

Three experiments investigated reasoners' beliefs about causal powers; that is, their beliefs about the capacity of a putative cause to produce a given effect. Covariation-based theories (e.g., Cheng, 1997; Kelley, 1973; Novick & Cheng, 2004) posit that beliefs in causal power are represented in terms of the degree of covariation between the cause and its effect; covariation is defined in terms of the degree to which the effect occurs in the presence of the cause, and fails tooccur in the absence (...) of the cause. To test the degree to which beliefs incausal power are reflected in beliefs about covariation information, participants in three experiments rated their beliefs that putative causes have the capacity to produce a given effect (i.e., possess the causal power to produce an effect) as well as their beliefs regarding the degree to which the putative cause and effectcovary. A strong positive correlation was discovered between participants' beliefs in causal power and their beliefs that the effect occurs in the presence of the cause. However, no direct relationship was found between participants' beliefs in causal power and their belief that the effect will fail tooccur in the absence of the cause. These findings were replicated using bothwithin- (Experiments 1 and 3) and between-subject designs (Experiment 2). In Experiment 3, we extended these analyses to measures of familiarity, imageability, and detailedness of the representation. We found that participants' beliefs in causal power were strongly associated with familiarity, and imageability, but not the perceived detailedness of the cause and effect relationship. These data provide support for a multidimensional account of causal knowledge whereby people's representations of causation include, but are not limited to, the covariation, familiarity, and imageability of cause and effect relationships.
