Psychologists have long debated the underlying cause of infants' perseverative reaching. Thelen et al. explain the error in terms of general processes that make goal-directed actions to remembered locations. The context- and experience-dependent nature of their model implies that there is no single cause of the A-not-B error, and, more generally, no core essence to cognitive development.

Hospital ethics committees have become widespread over the last 25 years, stimulated by the Quinlan decision of the New Jersey Supreme Court, the report of a President's Commission, and most recently by the Joint Commission on Accreditation of Health Care Organizations , which now man dates that each hospital seeking accreditation have a functioning process for the consideration of ethical issues in patient care. Laws and regulations in several states require that hospitals establish ethics committees, and some states stipulate that (...) certain types of cases and disputes be taken to such committees. At least one state grants legal immunity to those who implement recommendations of an ethics committee. (shrink)

Looking is a fundamental exploratory behavior by which infants acquire knowledge about the world. In theories of infant habituation, however, looking as an exploratory behavior has been deemphasized relative to the reliable nature with which looking indexes active cognitive processing. We present a new theory that connects looking to the dynamics of memory formation and formally implement this theory in a Dynamic Neural Field model that learns autonomously as it actively looks and looks away from a stimulus. We situate this (...) model in a habituation task and illustrate the mechanisms by which looking, encoding, working memory formation, and long-term memory formation give rise to habituation across multiple stimulus and task contexts. We also illustrate how the act of looking and the temporal dynamics of learning affect each other. Finally, we test a new hypothesis about the sources of developmental differences in looking.

Theories of cognitive development must address both the issue of how children bring their knowledge to bear on behavior in‐the‐moment, and how knowledge changes over time. We argue that seeking answers to these questions requires an appreciation of the dynamic nature of the developing system in its full, reciprocal complexity. We illustrate this dynamic complexity with results from two lines of research on early word learning. The first demonstrates how the child's active engagement with objects and people supports referent selection (...) via memories for what objects were previously seen in a cued location. The second set of results highlights changes in the role of novelty and attentional processes in referent selection and retention as children's knowledge of words and objects grows. Together this work suggests that understanding systems for perception, action, attention, and memory, and their complex interaction, is critical to understand word learning. We review recent literature that highlights the complex interactions between these processes in cognitive development and point to critical issues for future work. (shrink)

According to Jones & Love (J&L), Bayesian theories are too often isolated from other theories and behavioral processes. Here, we highlight examples of two types of isolation from the field of word learning. Specifically, Bayesian theories ignore emergence, critical to development theory, and have not probed the behavioral details of several key phenomena, such as the effect.

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children (...) with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U-shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U-shaped trend. (shrink)

Marr's seminal work laid out a program of research by specifying key questions for cognitive science at different levels of analysis. Because dynamic systems theory focuses on time and interdependence of components, DST research programs come to very different conclusions regarding the nature of cognitive change. We review a specific DST approach to cognitive-level processes: dynamic field theory. We review research applying DFT to several cognitive-level processes: object permanence, naming hierarchical categories, and inferring intent, that demonstrate the difference in understanding (...) of behavior and cognition that results from a DST perspective. These point to a central challenge for cognitive science research as defined by Marr—emergence. We argue that appreciating emergence raises questions about the utility of computational-level analyses and opens the door to insights concerning the origin of novel forms of behavior and thought. We contend this is one of the most fundamental questions about cognition and behavior. (shrink)

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

This paper critiques the biological race realism of Quayshawn Spencer. Spencer's recent embrace of “radical race pluralism” (RRP) is welcome but incomplete, because it needs methods that distinguish different communicative contexts for how American English speakers use “race” and related terms. I offer a pragmatic approach to identifying such contexts that combines pragmatic argumentation theory, rhetorical polysemy, and a pragmatic approach to definition. One consequence of embracing RRP is that Spencer's theory of “OMB race talk” is unsupportable (...) because it collapses three distinct communicative contexts: genomic research, legal and regulatory governance, and ordinary talk. By so doing, OMB race talk blocks attempts to fight racism and violates ethical standards that should allow people the agency to define their own identities. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Strangers in the Land: Blacks, Jews, Post-Holocaust AmericaKeith P. Feldman (bio)Eric J. Sundquist. Strangers in the Land: Blacks, Jews, Post-Holocaust America. Cambridge, MA: Harvard UP, 2005. 662 pp.Strangers in the Land: Blacks, Jews, Post-Holocaust America provides a wide-ranging, rich, and nuanced cultural history of what Eric J. Sundquist terms the "black-Jewish question" (2). In doing so, the book serves as both culmination and corrective to an already-expansive scholarly (...) literature on blacks and Jews generated since the late 1960s. Much of this scholarship has operated within a U.S.-centered paradigm to chart interethnic relations, laboring as it does to unpack, complicate, theorize, and otherwise come to understand the changing texture of black-Jewish relations and, in Sundquist's wods, its "intermixture of empathy, anxiety, and Hostility' (3)." Strangers in the Land stretches this paradigm to its limit, even as the diasporic imaginaries treated therein persistently escape a U.S. national imaginary and signal other possibilities for conceptualizing this tense and tender history.In its five hundred–plus pages of text, one hundred–plus pages of endnotes, and countless detailed footnotes (that are themselves illustrative and evocative), Sundquist has assembled a voluminous archive of textual material to show how works of the imagination by blacks and Jews have been "produced in a dynamic, multilayered historical matrix" that reveals the paradoxes of American liberalism (9). From the well-known and well-trodden (novels by Bellow, Roth, Malamud, and Morrison all play key roles) to the newly discovered and underappreciated (John A. Williams's Sons of Darkness, Sons of Light; Paule Marshall's The Chosen Place, the Timeless People; Gloria Naylor's Bailey's Café; William Melvin Kelley's A Different Drummer; Jon Michael Spencer's Tribes of Benjamin; Lore Segal's Her First American), Sundquist's careful historicism reveals how works of the imagination can serve as both microscopic and telescopic lenses through which to examine the vicissitudes of what he calls black and Jewish "interdependent self-conceptions" in the United States (5).Along with addressing a thick textual archive with subtlety and patience, Sundquist's major analytical innovation is that, unlike many of his predecessors, which frequently [End Page 63] positioned their analyses within the scarred domestic terrain of post–civil rights polarization, Sundquist's voracious curiosity dwells in the archive's heterogeneous details, allowing him to linger in examples that routinely exceed the simple polarization of blacks and Jews. The complex racial geography of New York boroughs and greater Chicagoland, for instance, is overlaid by Auschwitz and Egypt and Jerusalem, Ghana and Kenya and the Caribbean. In these settings, Sundquist spends time with figures only glimpsed in passing in other works: Arab Jews, Afro-Zionists, and anti-Zionists; Jews and Black Jews; Black Panthers, Israeli Black Panthers, Holocaust survivors, Holocaust deniers, Black Power advocates, and their Jewish Power doppelgangers. In a lengthy meditation on Harper Lee's To Kill a Mockingbird, Sundquist charts the novel's refractions of the problem of American racial equality in the wake of the Holocaust. Similarly, the careful readings of novels by Naylor, Williams, Spencer, and Kelley exemplify the rich results of Sundquist's method.This deeply historicist and intertextual project echoes Sundquist's 1993 epic work To Wake the Nations: Race in the Making of American Literature, which strenuously and quite effectively demonstrated how African American literature is constitutive of American literature, and not merely a minor subset of it. If this earlier work revealed the continued paradox of racial slavery in American conceptions of democracy, Strangers in the Land serves as something of a sequel. The book places another massive racial project, the systematic genocide of Europe's Jews, at the heart of twentieth-century American life. "The Holocaust," writes Sundquist, "became the benchmark against which at least one other case, African American slavery and its aftermath, has been judged" (6). By placing Jewish genocide at the center of his analysis, Sundquist importantly reminds us of the conclusion reached almost simultaneously by both Hannah Arendt and Aimé Césaire, that the Nazi racial project had its ideological origins in nineteenth-century European imperialism, and that this legacy bears indelibly on the present...

What responsibilities, if any, do we have towards our genetic offspring, before or after birth and perhaps even before creation, merely by virtue of the genetic link? What claims, if any, arise from the mere genetic parental relation? Should society through its legal arrangements allow 'fatherless' or 'motherless' children to be born, as the current law on medically assisted reproduction involving gamete donation in some legal systems does? Does the possibility of establishing genetic parentage with practical certainty necessitate reform of (...) current legal regimes of parenthood? And what limits, if any, should we set on parental procreative choices in the interests of future children, particularly with regard to genetic engineering and related techniques? These are the questions explored in this book by some of the foremost legal, bioethical and biomedical thinkers. Assembled with a view to assisting the reader to reflect critically on the ongoing social experiment which medically assisted reproduction is today, the essays in this collection highlight what are - and what else might in the nearby future become - possible reproductive options and respond to the difficulties we encounter in assessing these practices and possibilities from our traditional ethical vantage points. Contributions by: Andrew Bainham, Thomas Baldwin, Lisa Bortolotti, John Harris, Martin H. Johnson, Judith Masson, Martin Richards, Alison Shaw, Sally Sheldon, Bonnie Steinbock and Mary Warnock.

The main goal of this paper is to argue against Karl Rogers's attacks on realism in physics. Rogers argues that electrons do not exist independently of the relevant socio-technological process, but I show that such an assumption would make our best scientific theories incomprehensible. While the paper supports Rogers's attempts to refute positivism, it demonstrates that his own position is positivistic, and it corrects his overemphasis on the roles of technology and the experimenter. Rogers assumes that the founders of modern (...) science were simply mechanists, but I show how they were actually Platonic realists. Contrary to Rogers, realist faith in the fundamental unifying power of the laws of physics is shown to be reasonable, and any denial of this belief would imply that science is impossible. (shrink)

This volume attempts to give a short account of Herbert Spencer's life, an appreciation of his characteristics, and a statement of some of the services he rendered to science. Prominence has been given to his Autobiography, to his Principles of Biology, and to his position as a cosmic evolutionist; but little has been said of his psychology and sociology, which require another volume, or of his ethics and politics, or of his agnosticism-the whetstone of so many critics. Our appreciation (...) of Spencer's services is therefore partial, but it may not for that reason fail in its chief aim, that of illustrating the working of one of the most scientific minds that ever lived, -whose excess of science was almost unscientific.-.

Scholars loosely affiliated with the "Cambridge School" (e.g., Pocock, Skinner, Viroli, and Pettit) accentuate rule of law, common good, class equilibrium, and non-domination in Machiavelli's political thought and republicanism generally but underestimate the Florentine's preference for class conflict and ignore his insistence on elite accountability. The author argues that they obscure the extent to which Machiavelli is an anti-elitist critic of the republican tradition, which they fail to disclose was predominantly oligarchic. The prescriptive lessons these scholars draw from republicanism for (...) contemporary politics reinforce rather than reform the "senatorial," electorally based, and socioeconomically agnostic republican model (devised by Machiavelli's aristocratic interlocutor, Guicciardini, and refined by Montesquieu and Madison) that permits common citizens to acclaim but not determine government policies. Cambridge School textual interpretations and practical proposals have little connection with Machiavelli's "tribunate," class-specific model of popular government elaborated in The Discourses, one that relies on extra-electoral accountability techniques and embraces deliberative popular assemblies.

It is correctly asserted that the intensity of the current debate over the use of animals in biomedical research is unprecedented. The extent of expressed animosity and distrust has stunned many researchers. In response, researchers have tended to take a strategic defensive posture, which involves the assertion of several abstract positions that serve to obstruct resolution of the debate. Those abstractions include the notions that the animal protection movement is trivial and purely anti-intellectual in scope, that all science is good (...) (and some especially so), and the belief that an ethical consensus can never really be reached between the parties. (shrink)

One approach to the problem of differentiating a religious from a non- religious ethic would be to formulate a definition of religion that would clearly distinguish between religious and nonreligious traditions; however, a broad definition of religion would include some moral traditions, such as Marxism, commonly thought to be forms of secular humanism. A second approach would argue that some moral beliefs are independent, both in content and justification, of religious convictions; such a set of moral beliefs could be described (...) as a secular version of natural law. This approach would be rejected by those who argue that religious convictions go "all the way down." While the first can be debated by appealing to the heuristic value of various definitions of religion, the second involves familiar issues of moral epistemology. The author explores the consequences of holding a broad definition of religion and an "all the way down" epistemology. (shrink)

This commentary challenges the conclusions reached by Franklin Miller and Robert Truog in their criticism of the President's Council's White Paper, "Controversies in the Determination of Death." I agree with much of Miller and Truog's criticism of the rationale offered by the President's Council for accepting neurological criteria for determining death but argue that they too quickly dismiss the alternative rationale of determining death by neurological criteria-i.e., the destruction of the psychophysical integrity of the human being that occurs when the (...) potential for consciousness and every other mental function is lost due to catastrophic injury to the brain. By focusing on the death of bodies instead of human beings, their view absurdly implies that decapitation would not necessarily result in one's death. Since total brain failure is a form of physiological decapitation, the neurological criterion coheres perfectly well with the ordinary understanding of decapitation as death. (shrink)

This article analyzes Machiavelli's accounts of the historical figures Agathocles, Clearchus, Appius and Pacuvius to (1) accentuate the Florentine's distinction between tyranny and civic leadership, (2) identify the proper place of elite punishment and popular empowerment in his conception of democratic politics, and (3) criticize contemporary Straussian and "radical" interpreters of Machiavelli for profoundly underestimating the roles that popular judgment and popular rule play within his political thought.

Construal-level theory emphasizes that representing events at greater spatial, temporal, social, or hypothetical distance results in processing information at high construal levels (more conceptual, abstract). We posit that psychological distance and construal level are somewhat separable constructs, and can have different effects on emotion, and therefore, emotion regulation. We argue that psychological distance influences emotional appraisal, such that increasing distance results in lower emotion intensity, which can be leveraged to down-regulate emotions. However, we consider construal level a mindset, which can (...) occur with either high or low psychological distance. Furthermore, we argue that compared with psychological distance, construal level has a more nuanced relationship with emotion, and changing construal level for the purpose of changing emotion also requires considering the construal level of one's emotion-regulation goals.

This essay reevaluates the Weimar writings of Carl Schmitt and Leo Strauss, specifically, their intellectual efforts to replace the political authority of Kantian liberalism with, respectively, a ‘political theology’ and ‘Biblical atheism’ derived from the thought of early-modern state theorists like Hobbes and Spinoza. Schmitt and Strauss each insisted that post-Kantian Enlightenment rationality was unraveling into a way of thinking that violently rejected ‘form’ of any kind, fixated myopically on material things and lacked any conception of the external constraints that (...) invariably condition the possibilities of philosophy, morality and politics. They considered Kantian reason and liberal politics to pose serious threats to ‘genuine’ expressions of rationality and as dangerous obfuscations of the necessity of political order—of the brute fact that human beings stand in need of ‘being ruled,’ as such.

IN examining Herodotos' account of the Samian tyranny, historians have long been disturbed by two considerations. First, it seems strange that the period of settled tyranny should have begun no earlier than the rise of Polykrates and his two brothers c. 533 B.C., even though Samos was among the most advanced cities in Ionia. Yet it seems equally impossible to revise this accession date in an upward direction, at least by any significant margin. Furthermore, there had been at work in (...) Samos from c. 600 or earlier many of the factors which elsewhere in Ionia did in fact lead to a comparatively stable period of tyranny at that date, for instance at Miletos and Ephesos. Secondly, though Herodotos knows of no tyrant before Polykrates, it has been observed that the policies ascribed to him as characteristic were very largely the continuation of policies initiated a generation or more previously.

The increasingly pervasive practice of veiling among Muslim women has stimulated a great deal of scholarly investigation and debate. This study brings empirical evidence to bear on current debates about the meaning of the veil in Islam. This article first examines the conflicting meanings of the veil among Muslim religious elites and Islamic feminists. Although the dominant gender discourse among Muslim elites strongly favors this cultural practice, an antiveiling discourse promulgated by Islamic feminists has gained ground within recent years. This (...) study then examines how these discursive disputes affect gender identity negotiation among veiled and unveiled Muslim women living in Austin, Texas. Interviews with these women highlight how their gender identities reproduce and reformulate existing Muslim gender discourses. Special attention is paid to the subjective disparities and points of congruence between both groups of respondents. This study concludes by suggesting avenues for future research on the intersection of gender, religion, and cultural difference. (shrink)

This essay examines the two means by which Machiavelli thought republics could address the political problem of predatory socio-economic elites: Healthy republics, he proposes explicitly, should consistently check the “insolence of the nobles” by establishing constitutional offices like the Roman tribunes of the plebeians; corrupt republics, he suggests more subtly, should completely eliminate overweening oligarchs via the violent actions of a tyrannical individual. Roman-styled tribunes, wielding veto, legislative and accusatory authority, contain the oppressive behavior of socio-economic elites during normal republican (...) circumstances. By contrast, having overthrown a republic grown corrupt through oligarchic encroachment on the commonweal, Machiavelli suggests that Greek-styled tyrants lay the foundation for a more robust—that is, more egalitarian and martial—republic down the road by eliminating elites entirely and by instituting economic redistribution and military reforms.

There is increasing evidence that dynamic changes to chromatin, chromosomes and nuclear architecture are regulated by RNA signalling. Although the precise molecular mechanisms are not well understood, they appear to involve the differential recruitment of a hierarchy of generic chromatin modifying complexes and DNA methyltransferases to specific loci by RNAs during differentiation and development. A significant fraction of the genome-wide transcription of non-protein coding RNAs may be involved in this process, comprising a previously hidden layer of intermediary genetic information that (...) underpins developmental ontogeny and the differences between species, ecotypes and individuals. It is also evident that RNA editing is a primary means by which hardwired genetic information in animals can be altered by environmental signals, especially in the brain, indicating a dynamic RNA-mediated interplay between the transcriptome, the environment and the epigenome. Moreover, RNA-directed regulatory processes may also transfer epigenetic information not only within cells but also between cells and organ systems, as well as across generations. (shrink)

Nuestro interés en el contenido mental no-conceptual es, principalmente, la articulación de una versión sustantiva (no-trivial) de esta clase de contenido en la experiencia perceptual. El debate acerca del contenido no-conceptual ha girado, en su mayor parte, alrededor de su existencia; y los argumentos que se han ofrecido en su favor abogan por una versión no sustantiva según la cual el contenido no-conceptual es aquel que no satisface ciertos requisitos conceptuales. Así, para desarrollar una versión sustantiva del contenido mental no-conceptual (...) hemos apelado a la versión de la experiencia perceptual de propiedades espaciales ofrecida por Evans (1982 cap. 6). A partir de esto desarrollamos un nuevo argumento a favor del contenido no-conceptual de la experiencia perceptual que lo vincula a la actividad característica de la experiencia perceptual. Por último, exponemos uno de los ataques de McDowell (1996) a la noción de contenido no-conceptual y presentamos nuestras réplicas a este ataque, mostrando su insuficiencia. Al mostrar que la crítica de McDowell no es exitosa, consideramos que podríamos tener una versión del contenido no-conceptual de la experiencia que es inmune a esta línea de argumentación. (shrink)

A comprehensive look at the intellectual and cultural innovations of the Weimar period During its short lifespan, the Weimar Republic witnessed an unprecedented flowering of achievements in many areas, including psychology, political theory, physics, philosophy, literary and cultural criticism, and the arts. Leading intellectuals, scholars, and critics—such as Hannah Arendt, Walter Benjamin, Ernst Bloch, Bertolt Brecht, and Martin Heidegger—emerged during this time to become the foremost thinkers of the twentieth century. Even today, the Weimar era remains a vital resource for (...) new intellectual movements. In this incomparable collection, Weimar Thought presents both the specialist and the general reader a comprehensive guide and unified portrait of the most important innovators, themes, and trends of this fascinating period. The book is divided into four thematic sections: law, politics, and society; philosophy, theology, and science; aesthetics, literature, and film; and general cultural and social themes of the Weimar period. The volume brings together established and emerging scholars from a remarkable array of fields, and each individual essay serves as an overview for a particular discipline while offering distinctive critical engagement with relevant problems and debates. Whether used as an introductory companion or advanced scholarly resource, Weimar Thought provides insight into the rich developments behind the intellectual foundations of modernity. (shrink)
