Joint attention (JA) is hypothesized to have a close relationship with developing theory of mind (ToM) capabilities. We tested the co-occurrence of ToM and JA in social interactions between adults with no reported history of psychiatric illness or neurodevelopmental disorders. Participants engaged in an experimental task that encouraged nonverbal communication, including JA, and also ToM activity. We adapted an in-lab variant of experience sampling methods (Bryant, Coffey, Povinelli, & Pruett, 2013) to measure ToM during JA based on participants’ subjective reports (...) of their thoughts while performing the task. This experiment successfully elicited instances of JA in 17/20 dyads. We compared participants’ thought contents during episodes of JA and non-JA. Our results suggest that, in adults, JA and ToM may occur independently. (shrink)

The dominant public philosophy of the United States of America has long been some version of liberalism--dedicated to individual liberty, equal rights, religious freedom, government by consent, and established limits on political power. Today, however, we find ourselves in unusual times, when the major political parties have powerful and growing wings that embrace decidedly illiberal public philosophies. On the Left, critical theory eschews Enlightenment rationalism and liberal ideas of toleration and individual liberty as structures that serve to support inequality and (...) oppression. On the Right, conservative scholars excoriate liberalism for privileging an ideal of individual autonomy that eats away at the civilizing bonds of family, tradition, religion, and country. What seems new here is not the critiques themselves, but the power and popularity of political movements that openly and proudly reject the first principles of America's long-dominant public philosophy. Can the center hold? Can the principles of 1776 survive? Or has liberalism run its course? With these questions in the air, this book proposes to return with fresh eyes to the beginning of liberalism and the political philosophy of John Locke. Instead of looking at Lockean liberalism as a simple and timeworn ideological program, the essays reexamine Locke's project by remaining alive to the complexity and nuance with which he addressed his subject. The Locke that emerges is indeed an ambitious and radical thinker, but one not as imprudent or unmindful of custom as his conservative critics would have it, nor as tolerant of oppression as his progressive critics aver.

THE MOST SACRED FREEDOM includes eight essays that were first presented at the 2014 A.V. Elliott Conference on Great Books and Ideas, the seventh annual conference sponsored by Mercer Universitys Thomas C. and Ramona E. McDonald Center for Americas Founding Principles. Together, these essays explore the great principle of religious liberty by charting its development in the Western tradition and reconsidering its place at Americas founding. The book begins with a comparison between the flood accounts in Genesis and the Mesopotamian (...) Atra-Has's and advances all the way to the 2014 Supreme Court case Burwell v. Hobby Lobby. The intervening chapters examine the contributions of figures such as Emperor Julian, Roger Williams, Cecilius Calvert, John Locke, Jean-Jacques Rousseau, and the American Founders. Contributors to the volume are Steven Grosby, Jeremiah H. Russell, Maura Jane Farrelly, Daniel Cullen, John Witte, Jr., Scott Yenor, David Ramsey, and Michael Novak. (shrink)

DNA arrays have become the preferred method for large-scale expression measurement. Such data are needed in view of the large amounts of sequence data available: expression levels in a number of different tissues or situations provide a first step toward functional characterisation of new entities revealed by DNA sequencing. Although the basic principle of measurement is in all cases based on hybridisation of a mixed probe derived from tissue RNA to large sets of DNA fragments representing many genes, a number (...) of different forms of implementation of this principle are at hand. They are briefly described and compared, emphasizing the important issue of sensitivity and sample requirements and the accessibility of the methods to academic scientists. When these factors are taken into account, it appears that, contrary to a largely prevalent impression, the “best” approach is not necessarily always provided by the widely advertised glass microarrays or oligonucleotide chips.

The human cognitive architecture consists of a set of largely independent modules associated with different brain regions. This book discusses in detail how these various modules can combine to produce behaviours as varied as driving a car and solving an algebraic equation.

Social conditions of race and class continue to combine in ways that raise systemic questions about the adequacy and legitimacy of liberal, capitalist democracy in America. More radical alternatives, however, are still generally held to be irrelevant in the American context. The following is an effort to correct this widespread misrepresentation of socialism’s relevance to America generally, and to matters of race in particular. I consider the work of C.L.R. James who, fifty years ago, developed a class-oriented, explicitly Marxist theory (...) in which the aspirations and struggles of African-Americans were given a central place, both analytically and politically.

Can the output of human cognition be predicted from the assumption that it is an optimal response to the information-processing demands of the environment? A methodology called rational analysis is described for deriving predictions about cognitive phenomena using optimization assumptions. The predictions flow from the statistical structure of the environment and not the assumed structure of the mind. Bayesian inference is used, assuming that people start with a weak prior model of the world which they integrate with experience to develop (...) stronger models of specific aspects of the world. Cognitive performance maximizes the difference between the expected gain and cost of mental effort. Memory performance can be predicted on the assumption that retrieval seeks a maximal trade-off between the probability of finding the relevant memories and the effort required to do so; in categorization performance there is a similar trade-off between accuracy in predicting object features and the cost of hypothesis formation; in casual inference the trade-off is between accuracy in predicting future events and the cost of hypothesis formation; and in problem solving it is between the probability of achieving goals and the cost of both external and mental problem-solving search. The implemention of these rational prescriptions in neurally plausible architecture is also discussed. (shrink)

Disputes between those holding differing political views are ubiquitous and deep-seated, and they often follow common, recognizable lines. The supporters of tradition and stability, sometimes referred to as conservatives, do battle with the supporters of innovation and reform, sometimes referred to as liberals. Understanding the correlates of those distinct political orientations is probably a prerequisite for managing political disputes, which are a source of social conflict that can lead to frustration and even bloodshed. A rapidly growing body of empirical evidence (...) documents a multitude of ways in which liberals and conservatives differ from each other in purviews of life with little direct connection to politics, from tastes in art to desire for closure and from disgust sensitivity to the tendency to pursue new information, but the central theme of the differences is a matter of debate. In this article, we argue that one organizing element of the many differences between liberals and conservatives is the nature of their physiological and psychological responses to features of the environment that are negative. Compared with liberals, conservatives tend to register greater physiological responses to such stimuli and also to devote more psychological resources to them. Operating from this point of departure, we suggest approaches for refining understanding of the broad relationship between political views and response to the negative. We conclude with a discussion of normative implications, stressing that identifying differences across ideological groups is not tantamount to declaring one ideology superior to another. (shrink)

The appropriate methodology for psychological research depends on whether one is studying mental algorithms or their implementation. Mental algorithms are abstract specifications of the steps taken by procedures that run in the mind. Implementational issues concern the speed and reliability of these procedures. The algorithmic level can be explored only by studying across-task variation. This contrasts with psychology's dominant methodology of looking for within-task generalities, which is appropriate only for studying implementational issues.The implementation-algorithm distinction is related to a number of (...) other “levels” considered in cognitive science. Its realization in Anderson's ACT theory of cognition is discussed. Research at the algorithmic level is more promising because it is hard to make further fundamental scientific progress at the implementational level with the methodologies available. Protocol data, which are appropriate only for algorithm-level theories, provide a richer source than data at the implementational level. Research at the algorithmic level will also yield more insight into fundamental properties of human knowledge because it is the level at which significant learning transitions are defined.The best way to study the algorithmic level is to look for differential learning outcomes in pedagogical experiments that manipulate instructional experience. This provides control and prediction in realistically complex learning situations. The intelligent tutoring paradigm provides a particularly fruitful way to implement such experiments.The implications of this analysis for the issue of modularity of mind, the status of language, research on human/computer interaction, and connectionist models are also examined.

Much of cognitive psychology focuses on effects measured in tens of milliseconds while significant educational outcomes take tens of hours to achieve. The task of bridging this gap is analyzed in terms of Newell's (1990) bands of cognition—the Biological, Cognitive, Rational, and Social Bands. The 10 millisecond effects reside in his Biological Band while the significant learning outcomes reside in his Social Band. The paper assesses three theses: The Decomposition Thesis claims that learning occurring at the Social Band can be (...) reduced to learning occurring at lower bands. The Relevance Thesis claims that instructional outcomes at the Social Band can be improved by paying attention to cognition at the lower bands. The Modeling Thesis claims that cognitive modeling provides a basis for bridging between events on the small scale and desired outcomes on the large scale. The unit-task level, at the boundary of the Cognitive and Rational Bands, is useful for assessing these theses. There is good evidence for all three theses in efforts that bridge from the unit-task level to educational applications. While there is evidence for the Decomposition Thesis all the way down to the 10 millisecond level, more work needs to be done to establish the Relevance Thesis and particularly the Modeling Thesis at the lower levels.

We studied collaborative skill acquisition in a dynamic setting with the game Co-op Space Fortress. While gaining expertise, the majority of subjects became increasingly consistent in the role they adopted without being able to communicate. Moreover, they acted in anticipation of the future task state. We constructed a collaborative skill acquisition model in the cognitive architecture ACT-R that reproduced subject skill acquisition trajectory. It modeled role adoption through reinforcement learning and predictive processes through motion extrapolation and learned relevant control parameters (...) using both a reinforcement learning procedure and a new to ACT-R supervised learning procedure. This is the first integrated cognitive model of collaborative skill acquisition and, as such, gives us valuable insights into the multiple cognitive processes that are involved in learning to collaborate.

Multi-voxel pattern recognition techniques combined with Hidden Markov models can be used to discover the mental states that people go through in performing a task. The combined method identifies both the mental states and how their durations vary with experimental conditions. We apply this method to a task where participants solve novel mathematical problems. We identify four states in the solution of these problems: Encoding, Planning, Solving, and Respond. The method allows us to interpret what participants are doing on individual (...) problem-solving trials. The duration of the planning state varies on a trial-to-trial basis with novelty of the problem. The duration of solution stage similarly varies with the amount of computation needed to produce a solution once a plan is devised. The response stage similarly varies with the complexity of the answer produced. In addition, we identified a number of effects that ran counter to a prior model of the task. Thus, we were able to decompose the overall problem-solving time into estimates of its components and in way that serves to guide theory. (shrink)

LAS is a program that acquires augmented transition network (ATN) grammars. It requires as data sentences of the language and semantic network representatives of their meaning. In acquiring the ATN grammars, it induces the word classes of the language, the rules of formation for sentences, and the rules mapping sentences onto meaning. The induced ATN grammar can be used both for sentence generation and sentence comprehension. Critical to the performance of the program are assumptions that it makes about the relation (...) between sentence structure and surface structure (the graph deformation condition), about when word classes may be formed and when ATN networks may be merged, and about the structure of noun phrases. These assumptions seem to be good heuristics which are largely true for natural languages although they would not be true for many nonnatural languages. Provided these assumptions are satisfied LAS seems capable of learning any context‐free language. (shrink)

A comprehensive exploration of pragmatic themes emerging from neuroscientific research,illustrating why neurophilosophy should take this advancing pragmatist direction seriously.

An analysis of student learning with the LISP tutor indicates that while LISP is complex, learning it is simple. The key to factoring out the complexity of LISP is to monitor the learning of the 500 productions in the LISP tutor which describe the programming skill. The learning of these productions follows the power‐law learning curve typical of skill acquisition. There is transfer from other programming experience to the extent that this programming experience involves the same productions. Subjects appear to (...) differ only on the general dimensions of how well they acquire the productions and how well they retain the productions. Instructional manipulations such as remediation, content of feedback, and timing of feedback are effective to the extent they give students more practice programming, and explain to students why correct solutions work.

This volume has four parts; in Part I, dealing with the philosophical tradition, Francis M. Parker examines various senses of insight and discusses its goodness as an activity. Henry B. Veatch questions Wild's acceptance of the life-world and asks for a critical, explicitly transcendental justification of it. Robert Jordan reviews Anselm's ontological argument and its place in other proofs for God's existence, and in religious experience. John M. Anderson examines "Art and Philosophy" with the help of Plato and (...) Hegel. Part II examines the life-world; Robert R. Ehman writes on the phenomenon of world, and Calvin O. Schrag situates Husserl's notion of life-world within the tradition of Hegel, Dilthey and Heidegger as a theme in the problem of history. Enzo Paci has an essay relating the life-world to the Husserlian analysis of the body as a locus of mobility, life, sensation, and, ultimately thought. C. A. van Peursen's contribution examines the nature of structure in the life-world. Part III deals with the individual and society and includes a picturesque, sensitive and profound essay by Erwin Straus on "The Miser." George Schrader writes on "Monetary Value and Personal Value," W. L. McBride on "Individualisms," and Wilfrid Desan on "Sartre the Individualist." Part IV, "Subjectivity and Objectivity," includes Paul Ric£ur distinguishing three types of philosophical discourse about the will, and claiming that a hermeneutic of symbols must supplement both discourse which is phenomenological and that which proposes meaningful action. Mikel Dufrenne writes on "Structuralism and Humanism," Nathaniel Lawrence on "The Illusion of Monolinear Time," and Samuel J. Todes and Hubert L. Dreyfus on "The Existentialist Critique of Objectivity." James Edie has an important essay on Husserl's notion of "the grammatical" and the a priori in grammar; he relates it to Chomsky's theory of grammatical structures. The volume ends with a bibliography of Wild's works, reviews of them, and essays devoted to his thought.--R. S. (shrink)

Raciolinguistics reveals the central role that language plays in shaping our ideas about race and vice versa. The book brings together a team of leading scholars-working both within and beyond the United States-to share powerful, much-needed research that helps us understand the increasingly vexed relationships between race, ethnicity, and language in our rapidly changing world. Combining the innovative, cutting-edge approaches of race and ethnic studies with fine-grained linguistic analyses, authors cover a wide range of topics including the struggle over the (...) very term "African American," the racialized language education debates within the increasing number of "majority-minority" immigrant communities in the U.S., the dangers of multicultural education in a Europe that is struggling to meet the needs of new migrants, and the sociopolitical and cultural meanings of linguistic styles used in Brazilian favelas, South African townships, Mexican and Puerto Rican barrios in Chicago, and Korean American "cram schools" in New York City, among other sites. Taking into account rapidly changing demographics in the U.S and shifting cultural and media trends across the globe--from Hip Hop cultures, to transnational Mexican popular and street cultures, to Israeli reality TV, to new immigration trends across Africa and Europe--Raciolinguistics shapes the future of scholarship on race, ethnicity, and language. By taking a comparative look across a diverse range of language and literacy contexts, the volume seeks not only to set the research agenda in this burgeoning area of study, but also to help resolve pressing educational and political problems in some of the most contested raciolinguistic contexts in the world.

To ensnare the sophist of the Sophist in a definition disclosing him as a purveyor of images and falsehoods Plato must block the sophistical defence that image and falsehood are self-contradictory in concept, for they both embody the proposition proscribed by Parmenides — ‘What is not, is’. It has been assumed that Plato regards this defence as depending on a reading of ‘what is not’ in its very strongest sense, where it is equivalent to ‘what is not in any way’ (...) or ‘nothing’. Likewise, the initial paradoxes of not-being are seen as requiring that to mē on be understood in this way, that later designated by Plato as the opposite of to on or ‘being’. On this interpretation, Plato's counter-strategy is to recognise a use of to mē on which is not opposed in this strict sense to being, but is indeed a part of it and is ‘being other than’. In a stimulating article, R. W. Jordan challenges this account. I shall briefly attempt to show that his objections are not decisive and that his own interpretation is open to question. Jordan makes the interesting suggestion that a distinction between two senses of not-being, where one is equivalent to nothing and one is not, dates from the middle dialogues — particularly from Republic V, where objects of agnoia are mēdamē onta and objects of doxa are both onta and mē onta. He concludes, ‘Malcolm's view, then, seems to amount to this: that Plato is now extending the moral he draws about objects of belief in the Republic to cover forms. Forms too now are seen to be both being and notbeing.’. (shrink)

Environmentalism is usually thought to be a liberal political position, but the two primary schools of thought within the conservative intellectual movement support environmentalism as well. The free market perspective has received considerable attention for its potential contributions to environmental protection, but the traditionalist perspective has not. In this essay, I consider several important principles of traditionalist conservatism. The traditionalists are not materialists and are highly critical of our consumer culture. They reject ideology and stress piety toward nature, the intergenerational (...) character of society, and prudence in political and social action. These basic principles are a solid foundation for environmentalism. (shrink)

In a free society, it is common to hear the request that one â ~keep an open mind.â Just what exactly is it, however, to keep an open-mind? How does open-mindedness function? How does it square with important personal commitments? These issues are particularly acute when it comes to matters of religious belief in which open-mindedness can sound to the pious a bit too much like doubt. Certainly, in a discipline whose discourse remains rational dialogue, effort should be spent discerning (...) the contours of this virtue, especially in light of its formal role in establishing responsiveness to new inquiries in matters philosophical and religious. This book provides a collection of essays serving to promote conversation about open-mindedness, its virtue, and its role and application in problems in the philosophy of religion in particular.

The book Time and Eternity , the English version of Zeit und Ewigkeit , by Antje Jackelén, contains scientific and theological treatments of these two topics, starting with the usage of such ideas in German, Swedish, and English hymns.

In lieu of an abstract, here is a brief excerpt of the content:THE NON-INFALLIBLE MORAL TEACIDNG OF THE CHURCH T:HE CHURCH has always claimed the authority to each in the name of Christ. This authority is given to he Pope and to the Bishops in union with him. It is their duty to hand on the Christian message and keep it intact. The duty of the rest of the faithful is to follow this teaching. The Latin term used to express (...) this following is obsequium religiosum.1 This is not an easy term to translate into English but in general it has been taken to mean religious assent. The use of the word assent implies that it is the human intellect that is engaged. Following Church teaching is not just a matter of obedience to a superior or observance of law, that is, of acting in a manner in accord with some precept or legislation. Obedience and observance are basically a matter of the will and external execution of a command but do not necessarily imply intellectual engagement, at least on the level of assent. It is quite true that if obedience or observance are to be human acts at all, there must be an understanding of what is commanded. But it is possible to observe a law or command without agreeing with it. And it is execution primarily that obedience and observance of law call for. If one does what is commanded either by an authority or by law, he is fulfilling his basic obligation. He may or may not agree with the command given. In other words intellectual assent is not in itself the response called for by this kind of authority. In fact, intellectual assent as such is not and cannot be required by law. When it is given, it is the magis.2 1 Vatican II, The Church, n. 25. Documents of Vatican II, Austin Flannery, O.P. (New York: Costello, 1975) 379. 2 For a full treatment of intellectual obedience see the letter on the virtue of obedience of St. Ignatius Loyola, especially n. 9 ff. Rules of the Society of Jesus, (Woodstock: Woodstock Press, 1956) 65 ff. I 2 JOHN R. CONNERY, S.J. We do not mean to imply that agreement with a law or command is irrelevant. There is good reason to believe that continued observance or obedience is intimately related to agreement with a law or precept. Where there is conflict, observance may be very difficult, and may not survive at all. What we are saying is that a precept or a law aims primarily at performance, not at assent. Agreement will indeed be desirable, but as a guarantee of performance. In itself it is not a requirement of obedience or observance. But assent is the proper response to teaching. So teaching differs from a precept or a law in this respect. Obedience or observance is the response to the latter, and these may be given with or without intellectual assent. But when one is dealing with teaching, assent is called for. From the above it is clear that in claiming the authority to teach, the Church is claiming a power which even civil governments do not claim. Civil government has ruling or governing power; it makes no claim to teaching authority. So it cannot require intellectual assent to its demands. And the same is true of other human organizations, even those of a religious nature. Authorities in them may have ruling or governing power of some kind, but this is the limit of their authority. There are, of course, many teachers in our world. Anyone who imparts information or knowledge to another is a teacher. Ordinarily, however, the title is reserved to those who have a certain competence in the field in which they teach and are teachers by profession. The claim of the Church goes beyond this kind of teaching, even when the teaching is in the area of theology. It is the claim to teach in the name of Christ.3 This makes the teaching of the Church different from other teaching. It must be admitted that when one is dealing with teaching, especially moral teaching, more than an intellectual response is called for. Assent to teaching must... (shrink)

For the basic areas of physics‐classical mechanics, classical field theories, and quantum mechanics‐there are local dynamical theories that offer complete descriptions of systems when the proper subsidiary conditions also are provided. For all these cases there are global theories from which the local theories can be derived. Symmetries and their relation to conservation laws are reviewed. The standard model of elementary particles is mentioned, along with frontier questions about them. A case against reductionism in physics is presented.

Cosmology, the study of the universe, has a past, which is reviewed here. The standard model—the Big Bang, or the hot, dense early universe that is still expanding—is based on observations that are basically consistent but which require additional input to improve the agreement. Out of the early universe came the galaxies and stars that shine today. The future of the universe depends on the density of matter: too much mass leads to the Big Crunch; too little leads to eternal (...) expans ion and cooling. The dark‐matter problem prevents us from knowing which will be the fate of the universe. Thelimits of what may be called “scientific” are addressed. (shrink)
