This study is an attempt to contribute data concerning the cognitive functioning and development of intellectually gifted children, at the threshold of formal operational stage. It ascribes to the theory of the operational development of intelligence according to Piaget. “Gifted”, children and “average” children of an equivalent mental age (12 years and 6 months) were compared. A second group of gifted children of the same chronological age as the average children completed this study. Longeot's “Échelle de Développement de la Pensée Logique” was used for all the subjects. The results reveal dissynchronical aspects within the genesis of gifted children. They are discussed taking into account the task characteristics (type of reasoning they require) and functional specificities of compared subjects.  相似文献

A common way of studying developmental disorders is to adopt a static neuropsychological deficit approach, in which the brain is characterized in terms of a normal brain with some parts or ‘modules’ impaired. In this paper we outline a neuroconstructivist approach in which developmental disorders are viewed as alternative developmental trajectories in the emergence of representations within neural networks. As a concrete instantiation of the assumptions underlying this general approach, we present a number of simulations in an artificial neural network model. The representations that emerge under different architectural, input and developmental timing conditions are then analysed within a multi‐dimensional state space. We explore alternative developmental trajectories in these simulations, demonstrating how initial differences in the same parameter can lead to very different outcomes, and conversely how different starting states can sometimes result in similar end states (phenotypes). We conclude that the assumptions of the neuroconstructivist approach are likely to be more appropriate for analysing developmental deviations in complex dynamic neural networks, such as the human brain.  相似文献

The aim of this study was to examine the effects of intergroup contact, personality, and demographic characteristics on the intergroup attitudes of police officers, medical doctors and nurses (N=421; 274 females, 147 males). Following the contact hypothesis, intergroup contact in and of itself was not expected to be sufficient for reducing intergroup prejudice, especially in unequal contacts between professionals and their clients. It was argued that the quality of contact required for the improvement of intergroup attitudes is not equal status or emotional closeness of the participants, but rather that of individuation and familiarity of the outgroup member. The results showed that both level of authoritarianism and individuation of an outgroup member affected intergroup attitudes across all types of contact. For authoritarianism, this result did not hold separately for males, but the individuation effect was very stable; those who knew an outgroup member only superficially held more negative intergroup attitudes than those who knew him or her well, even in unequal and non‐voluntary contacts, and even when controlling for authoritarianism, gender, education and professional field. The effect was non‐significant in voluntary contacts. No differences in intergroup attitudes were found between males and females or between the professional groups among males after controlling for authoritarianism.

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception of mathematical knowledge, in particular mathematical growth.  相似文献

This article examines the contribution to ecumenical dialogue of Ion Bria, an important Romanian theological and ecumenical personality. The value of his approaches is demonstrated by the fact that many contemporary authors start their research from his ideas, such as the concept of the “liturgy after the liturgy,” of which he was a significant proponent, and which are still relevant to ecumenical dialogue. At the time they were first proposed, they shifted ecumenical dialogue. Bria was also a good and careful observer of ecumenical and pan‐Orthodox reality. He presented with objectivity the reality from his home space and made valuable comparisons between his spirituality and other confessional approaches, offering new topics of dialogue and creating bridges between churches.  相似文献

In this critical, feminist account of the management of intersex conditions under 2006’s controversial “Disorders of Sex Development” (DSD) treatment model, I argue that like the “Optimal Gender of Rearing” (OGR) treatment model it replaced, DSD aims at securing a cisgendered future for the intersex patient, referring to a normalized trajectory of development across the lifespan in which multiple sexed, gendered, and sexual characteristics remain in “coherent” alignment. I argue this by critically analyzing two ways that intersex management has changed between OGR and DSD: 1) regarding sex‐assignment recommendations for three patient populations and, 2) with the prenatal treatment of pregnant individuals at risk of conceiving a fetus with congenital adrenal hyperplasia with the steroid hormone dexamethasone. I conclude that like OGR before it, DSD also unjustifiably presumes that typical genitalia are necessary for cisgendered development. However, unlike OGR, it appeals to the empirically inadequate, theoretically suspect, and biologically determinist model of gender development known as brain‐organization theory. Given this, I conclude that the treatment of intersex people under DSD continues to be driven by problematically heterosexist and transphobic assumptions regarding the value and normalcy of cisgendered life, while practically and discursively constituting it as such.  相似文献

This article argues that environmental ethics can deemphasize environmental problem‐solving in preference for a more exemplarist mode. This mode will renarrate what we admire in those we have long admired, in order to make them resonate with contemporary ethical needs. First, I outline a method problem that arose for me in ethnographic fieldwork, a problem that I call, far too reductively, “solution thinking.” Second, I relate that method problem to movements against “quandary ethics” in ethical theory more broadly. Third, I discuss some interpretive work I am engaged in about Henry David Thoreau and how it bears on the methodological issues my fieldwork raised. I argue that some of the most important icons of right relation to environment, especially Francis of Assisi and Thoreau, should be envisioned as far more politically invested than they usually are. They demonstrate to scholars of religious ethics that an exemplarist ethic focused on character need not neglect politics.  相似文献

John H. Evans's recent book Morals Not Knowledge is a timely argument to recognize broader social and cultural factors that might impact what U.S. religious publics think about the relationship between science and religion and their attitudes toward science and/or religion. While Evans's focus is primarily on what can be classed as moral issues, this response argues that there are other factors that sit within neither the older epistemic conflict model approach nor a moral conflict model approach that also merit further investigation. There is a significant need for further research that examines the social, psychological, (geo)political, and broader cultural factors shaping people's social identities in relation to science and religion debates. When undertaking such research, we need to be wary of creating a binary between scholarly and public space discourse. Social scientific research in this field should be led by public perceptions, attitudes, and views, not by concepts or frameworks that we project onto them.  相似文献
