This paper reviews the fate of the central ideas behind the complementary learning systems (CLS) framework as originally articulated in McClelland, McNaughton, and O’Reilly (1995). This framework explains why the brain requires two differentially specialized learning and memory systems, and it nicely specifies their central properties (i.e., the hippocampus as a sparse, pattern-separated system for rapidly learning episodic memories, and the neocortex as a distributed, overlapping system for gradually integrating across episodes to extract latent semantic structure). We review the application (...) of the CLS framework to a range of important topics, including the following: the basic neural processes of hippocampal memory encoding and recall, conjunctive encoding, human recognition memory, consolidation of initial hippocampal learning in cortex, dynamic modulation of encoding versus recall, and the synergistic interactions between hippocampus and neocortex. Overall, the CLS framework remains a vital theoretical force in the field, with the empirical data over the past 15 years generally confirming its key principles. (shrink)

The prefrontal cortex is widely believed to play an important role in facilitating people's ability to switch performance between different tasks. We present a biologically‐based computational model of prefrontal cortex (PFC) that explains its role in task switching in terms of the greater flexibility conferred by activation‐based working memory representations in PFC, as compared with more slowly adapting weight‐based memory mechanisms. Specifically we show that PFC representations can be rapidly updated when a task switches via a dynamic gating mechanism based (...) on a temporal‐differences reward‐prediction learning mechanism. Unlike prior models of this type, the present model develops all of its internal representations via learning mechanisms as shaped by the demands of continuous periodic task switching. This advance opens up a new domain of research into the interactions between working memory task demands and the representations that develop to meet them. Results on a version of the Wisconsin card sorting task are presented for the full model and a number of comparison networks that test the importance of various model features. Furthermore, we show that a lesioned model produces perseverative errors like those seen in frontal patients. (shrink)

The posterior cortex, hippocampus, and prefrontal cortex in the Leabra architecture are specialized in terms of various neural parameters, and thus are predilections for learning and processing, but domain-general in terms of cognitive functions such as face recognition. Also, these areas are not encapsulated and violate Fodorian criteria for modularity. Anderson's terminology obscures these important points, but we applaud his overall message.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

An animal confronts numerous challenges when constructing an optimal navigational route. Spatial representations used for path optimization are likely constrained by critical environmental factors that dictate which neural systems control navigation. Multiple coding schemes depend upon their ecological relevance for a particular species, particularly when dealing with the third, or vertical, dimension of space.

This instalment is a reworking of the paper I gave at the meeting in Oxford in 2002 to a very small audience who I thank heartily for their patience and comments. I tried there to muse upon some ideas precipitated by reading two books by Jeremy Waldron, a legal philosopher whose work I find succeeds in being interesting and accessible without sacrificing technical content. I first came across his work whilst working on my PhD and was fascinated by his approach (...) and learning — even when I did not understand or agree with him. In one paper he made a point that struck a very important chord with me in relation to questions of participation within development:Philosophers who talk about rights should pay much more attention than they do to the processes by which decisions are taken in a community under circumstances of disagreement. Theories of rights need to be complemented by theories of authority, whose function it is to determine how decisions are to be taken when the members of a community disagree about what decision is right.I would like to suggest that within the Development Industry it is not only philosophers who need to pay more attention to these issues, but also development professionals who work with issues of governance as well as participation at the grass roots. This is not an obvious linkage, I admit, but one which I hope thisdiary entry will make clear.I will try to show that acknowledging disagreement within the legislative and judicial fields might actually be a positive move. And, as Waldron also indicates, that there is something dynamic and positive about the participation of people in processes. I will examine some current thinking on participation in development projects and ask whether current practices may be hindering the 'freedom to disagree'. I conclude that the failure to address some aspects of development practice relating to power and the possibility of disagreement is an issue. I highlight some factors which inhibit participation and suggest they flow from failures to develop strategies that foster local participation in contexts where local people often lack the formal' knowledge they need if they are to negotiate successfully with what James C Scott has called 'institutional privilege.'.

Since the appearance of his earliest works on the subject of the emotions, namely, his article “Emotions and Choice” in 1973 and his book The Passions in 1976, Robert C. Solomon has never ceased to develop the idea that we are in some significant sense and to some significant degree responsible for our emotions. His presentation of this thesis in these two works was, on his own admission, somewhat polemical and stood in need of considerable revision. This present volume, which (...) brings together twelve different articles, beginning with “Emotions and Choice” and concluding with two papers from the year 2001, allows those interested in emotion theory to follow in great detail the contours of the development of the thought of one of the most important figures working in this field.

ABSTRACT There is limited guidance about whether and how to provide psychological assessment results to research participants. This paper considers several ethical challenges associated with offering individual research results in psychological assessment research. Additionally, the process used to return individual results within a study examining neurodevelopmental effects of anesthesia exposure in children and adolescents is described. Almost all participants requested to know if results were concerning; however, only around a third of those with concerning findings sought additional feedback. Ongoing research (...) and guidance are necessary to establish evidence-based practices and manage challenges that may emerge when disclosing such results. (shrink)

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

To explore the realm of creativity, we will make use of the concept of instauration as articulated in the work of Étienne Souriau. Although infrequently used, the word remains extant in English, with agreement among dictionaries that the primary definition is the action of restoring or renewing, with a secondary meaning of instituting or founding. While both senses are at play in Souriau’s thought, it is perhaps the tension between the two that is predominantly in question, akin to what we (...) describe as open containment. We think instauration, as institutive renewal, in dialogue with Merleau-Ponty’s late use of the term aesthesiology to further elaborate the process of creating as a return to the wonder that is aesthesis, the affectively and sensually apprehended opening onto and entanglement with what is. Merleau-Ponty extends aesthesiology as the science of the sense organs themselves into a philosophical organology for ontology. His use of aesthesiology and Souriau’s use of instauration constitute efforts to offer sufficient conceptual containment to be able to say the contingent and ambiguous open of ongoing originating, even while both thinkers strive not to institute any final closure by this very act of naming. This is the inevitable tension of writing philosophic creation.Pour explorer le royaume de la créativité, nous utilisons ici le concept d’instauration tel qu’il a été articulé dans l’oeuvre d’Étienne Souriau. Quoique utilisé rarement, ce terme est attesté dans la langue anglaise. Les dictionnaires anglais accordent que sa définition principale désigne une action de rétablissement ou de renouvellement, avec un sens secondaire d’institution ou fondation. Si les deux sens sont à l’oeuvre chez Souriau, c’est peut-être la tension entre eux qui y est surtout patente. Nous pensons ici l’instauration, entendue comme renouvellement instituant, en dialogue avec l’idée d’esthésiologie telle que Merleau-Ponty la comprend à la fin de son oeuvre. Il utilise cette notion pour développer sa conception du processus de création comme retour à l’étonnement que produit l’áisthesis. L’áisthesis est en effet l’ouverture, affective et sensible, et l’entrelacs, affectif et sensible, à ce qui est. Merleau-Ponty prolonge ainsi l’esthésiologie entendue comme science des organes sensibles, vers une organologie philosophique à visée ontologique. L’usage de l’esthésiologie chez Merleau-Ponty et l’usage de l’instauration chez Souriau constituent des efforts vers une maîtrise conceptuelle suffisante pour pouvoir dire l’ouverture continue, contingente et ambiguë de l’originaire – bien que les deux penseurs ne visent pas à instaurer une clôture finale à partir de l’acte nominatif. Telle est la tension inévitable qu’on rencontre lorsqu’on cherche à écrire la création philosophique.Utilizzeremo in queste pagine per esplorare il regno della creatività il concetto di “instaurazione” così come si trova articolato nell’opera di Étienne Souriau. Benché impiegato raramente, questo termine è attestato anche nella lingua inglese. I dizionari inglesi danno come significato principale quello di un’azione di ristabilimento o rinnovamento, a cui si aggiunge un significato secondario di istituzione o fondazione. Se è vero che entrambi i significati sono all’opera in Souriau, è d’altra parte ancor più evidente la loro tensione. Proporremo qui di pensare l’instaurazione, intesa come rinnovamento istituente, in dialogo con l’idea di estesiologia così come la intende Merleau-Ponty alla fine del suo percorso. Egli usa questa nozione per sviluppare la sua concezione del processo creativo come ritorno allo stupore dell’áisthesis, cioè dell’apertura affettiva e sensibile, e dell’intreccio affettivo e sensibile, a ciò che è. Merleau-Ponty prolunga così l’estesiologia come scienza degli organi di senso in direzione di un’organologia filosofica orientata ontologicamente. L’indagine sull’estesiologia condotta da Merleau-Ponty e l’uso del concetto di instaurazione in Souriau costituiscono così altrettanti sforzi di dire concettualmente l’apertura continua, contingente e ambigua dell’originario – benché sia chiaro che i due pensatori non intendono raggiungere in alcun modo, con questo dire concettuale e con questa scelta lessicale, una qualsiasi “chiusura” della questione. Tale è infatti la tensione inevitabile cui ci si ritrova esposti quando si tenta di scrivere la creazione. (shrink)

This volume is a collection of 16 essays, old and new, relating history and exegesis in the writings of Bede and Adomnán, and in the lives of Thomas Becket. The first part consists of seven studies of Bede's writings, notably his biblical commentaries and his Ecclesiastical History. Two of the essays are published here for the first time. The five studies in the second part, devoted to Adomnán, discuss his life of Saint Columba (the Vita Columbae) and his guide to (...) the Holy Places (De locis sanctis). One essay ('The Bible as Map'), published posthumously, compares his presentation of a major theme, the earthly and heavenly Jerusalem, with the approach adopted by Bede. The third section consists of two essays on the lives of Thomas Becket that were composed shortly after his death. They examine, in the context of patristic exegesis, the biblical images invoked in the texts in order to show how the saint's biographers understood the complex relationship between hagiography and history. With the exception of the Jarrow Lecture on Bede and the essays on Becket, the studies in both parts were published originally in edited books, some of them now hard to come by. (shrink)

The book argues that the category of mother is distinct from the category of woman and that many of the problems mothers face-socially, economically, politically, culturally, and psychologically-are specific to women's work and identity as mothers. Indeed, mothers, arguably more so than women in general, remain disempowered despite forty years of feminism. Mothers, thus, need a feminism of their own, one that positions mothers' concerns as the starting point for a theory and politic of empowerment. O'Reilly terms this new (...) mode of feminism matricentic feminism and the book explores how it is represented and experienced in theory, activism, and practice. The chapter on maternal theory examines the central theoretical concepts of maternal scholarship to include Adrienne Rich's distinction between mothering and motherhood, Sara Ruddick's model of maternal thinking and practice and Patricia Hill Collins' concept of othermothering while the chapter on activism considers the 21st century motherhood movement. Feminist mothering is likewise examined as the specific practice of matricentric feminism and this chapter discusses varies theories and strategies on and for maternal empowerment. Matricentric feminism is also examined in relation to the larger field of Feminist Theory and Women's Studies; here O'Reilly persuasively shows how matricentric feminism has been marginalized in feminist scholarship and considers the reasons for such exclusion and how such may be challenged and changed.

This volume of essays retrieves the largely unresearched thought and the original ideas of ancient women philosophers and carves out a space for them in the canon. The broad focus includes women thinkers in ancient Indian, Chinese, and Arabic philosophy as well as in the Greek and Roman philosophical traditions.

This paper is a response to and discussion of Maddalena Bonelli’s “Women philosophers in antiquity: Open questions and some results.” It also aims to advance the general discussion of the issues Bonelli raises. In it I contextualise Bonelli’s discussion, and take up three of her questions: What is the status of the work of restoring ancient women to the philosophical canon? What criteria ought we to use to decide who counts as a philosopher? What sort of philosophy did women practice (...) in antiquity, and in what ways might the restoration of ancient women thinkers to the canon change the way we conceive of ancient philosophy itself? I consider the way in which Bonelli’s paper advances the discussion of each question, raise some worries about the discussions, and provide suggestions for how we might think about these issues further. I maintain that the reshaping of the philosophical canon that takes place when we integrate ancient women involves a reshaping of the discipline, and of our methods for accessing it. This is a result I argue we ought to embrace rather than resist. I conclude with a summary of the main contributions of Bonelli’s paper. (shrink)

This article appeals to Thomas Aquinas in order to offer a construal of the nature of reason arguably preferable to that prominent in the Enlightenment. Thomas’s account neither espouses the notion that reason is devoid of any appetitive influence nor so conflates reason and will as to suggest that thinking becomes essentially a form of willing. His view does respect that the activity of willing is of fundamental import for the life of reason. Since the ultimate object of the will (...) is union with God, it follows that the virtue that specifically promotes the attainment of this end—the virtue of religion—has particular import because it aims at rectifying the will and is the most excellent among the moral virtues. In brief, this virtue promotes the optimal intellectual and moral flourishing of individuals as well as the realization of justice in society. (shrink)

Research consent processes must provide potential participants with the necessary information to help them decide if they wish to join a study. On the Oxford ‘A’ Research Ethics Committee we’ve found that current research proposals mostly provide adequate detail (even if not in an easily comprehensible format), but often fail to support decision making, a view supported by published evidence. In a previous paper, we described how consent might be structured, and here we develop the concept of an Information and (...) Decision Aid (IDA) that can support decision making and be used to guide the dialogue between researcher and potential participant. Our proposal requires limited changes to current processes or paperwork and would provide an easily accessible document for others that the potential participant might approach for advice. It could later be integrated with the Informed Consent Form to ensure all matters of concern to the individual participant have been addressed before consent is formally signed off. (shrink)

This paper examines the investigations carried out between 1798 and 1834 to determine whether, and how, magnetism affected the rate at which marine chronometers gained or lost time. There were persistent claims that chronometers systematically altered rate between those determined on land and those at sea, and magnetism was thought by some to be the most likely cause. Others disputed any rate difference at all. The experiments carried out to determine the influence of magnetism and those carried out to determine (...) if there was a difference between land and sea rates of chronometers will be considered. The data will be re-analysed in an attempt to extract additional information to clarify the answers to these questions. The influence these experiments had on certain navigational practices will be discussed briefly. (shrink)

John Calvin claims that the foundation of Scripture is the oracles and visions revealed to the patriarchs, transmitted through countless generations by an oral tradition that faithfully preserved these oracles. The oral tradition of the patriarchs also contains practices not found in written Scripture that are applicable to the church of Calvin day.

With a few exceptions, Thomists have by and large failed to engage with the historical and hermeneutical turns in philosophy and theology. This article offers an account of what the beginnings of a Thomistic engagement with recent hermeneutical philosophy might look like. In order to develop such an account, the author turns to arguably the most important contemporary hermeneutical philosopher, namely Hans-Georg Gadamer, as a dialogue partner. Despite claims to the contrary, this article argues that Gadamer does not successfully deal (...) with the specter of relativism. It goes on to show how that the thought of Thomas Aquinas can ably deal with this specter. There are two central elements in the argument put forward. Firstly, the author argues that the human being exists in between God as First Efficient Cause of all that exists and God as Final Cause of all that exists. This existence between God as First Efficient Cause of all that exists and God as Final Cause of all that exists furnishes the connatural context in which human knowing and willing unfolds. Secondly, he considers the dynamics of “interinvolvement” between intellect and will. The upshot of these arguments is a construal of reason that is at once capable of universal truth and hermeneutical in nature. Indeed, the universal range of reason and its hermeneutical dimension are in no way opposed to each other: they are rather dual aspects of one and the same reality. (shrink)
