Symbolic arithmetic is fundamental to science, technology and economics, but its acquisition by children typically requires years of effort, instruction and drill1,2. When adults perform mental arithmetic, they activate nonsymbolic, approximate number representations3,4, and their performance suffers if this nonsymbolic system is impaired5. Nonsymbolic number representations also allow adults, children, and even infants to add or subtract pairs of dot arrays and to compare the resulting sum or difference to a third array, provided that only approximate accuracy is required6–10. Here (...) we report that young children, who have mastered verbal counting and are on the threshold of arithmetic instruction, can build on their nonsymbolic number system to perform symbolic addition and subtraction11–15. Children across a broad socio-economic spectrum solved symbolic problems involving approximate addition or subtraction of large numbers, both in a laboratory test and in a school setting. Aspects of symbolic arithmetic therefore lie within the reach of children who have learned no algorithms for manipulating numerical symbols. Our findings help to delimit the sources of children’s difficulties learning symbolic arithmetic, and they suggest ways to enhance children’s engagement with formal mathematics. We presented children with approximate symbolic arithmetic problems in a format that parallels previous tests of non-symbolic arithmetic in preschool children8,9. In the first experiment, five- to six-year-old children were given problems such as ‘‘If you had twenty-four stickers and I gave you twenty-seven more, would you have more or less than thirty-five stickers?’’. Children performed well above chance (65.0%, t1952.77, P 5 0.012) without resorting to guessing or comparison strategies that could serve as alternatives to arithmetic. Children who have been taught no symbolic arithmetic therefore have some ability to perform symbolic addition problems. The children’s performance nevertheless fell short of performance on non-symbolic arithmetic tasks using equivalent addition problems with numbers presented as arrays of dots and with the addition operation conveyed by successive motions of the dots into a box (71.3% correct, F1,345 4.26, P 5 0.047)8..

Several hundred thousand intellectually talented 12-to 13-year-olds have been tested nationwide over the past 16 years with the mathematics and verbal sections of the Scholastic Aptitude Test (SAT). Although no sex differences in verbal ability have been found, there have been consistent sex differences favoring males in mathematical reasoning ability, as measured by the mathematics section of the SAT (SAT-M). These differences are most pronounced at the highest levels of mathematical reasoning, they are stable over time, and they are observed (...) in other countries as well. The sex difference in mathematical reasoning ability can predict subsequent sex differences in achievement in mathematics and science and is therefore of practical importance. To date a primarily environmental explanation for the difference in ability has not received support from the numerous studies conducted over many years by the staff of Study of Mathematically Precocious Youth (SMPY) and others. We have studied some of the classical environmental hypotheses: attitudes toward mathematics, perceived usefulness of mathematics, confidence, expectations/ encouragement from parents and others, sex-typing, and differential course-taking. In addition, several physiological correlates of extremely high mathematical reasoning ability have been identified (left-handedness, allergies, myopia, and perhaps bilateral representation of cognitive functions and prenatal hormonal exposure). It is therefore proposed that the sex difference in SAT-M scores among intellectually talented students, which may be related to greater male variability, results from both environmental and biological factors.

Can rational agents coordinate in simultaneous interactions? According to standard game theory they cannot, even if there is a uniquely best way of doing so. To solve this problem we propose an argument in favor of ‘belief-less reasoning’, a mode of inference that leads to converge on the optimal solution ignoring the beliefs of the other players. We argue that belief-less reasoning is supported by a commonsensical Principle of Relevant Information that every theory of rational decision must satisfy. We show (...) that this principle can be used to justify (some versions of) team reasoning, as well as other schemes of practical reasoning that do not involve sophisticated meta-representation.

Abstract What sense are we to make of the promise of love against the contingency of human life? I discuss two replies to this question: (1) the suggestion that marriage, based on the probable success of this kind of relationship, is a more or less worthwhile endeavour (cf. Moller and Landau), and (2) Martha Nussbaum's Aristotelian proposal that we only live life fully if we embrace aspects of life, such as loving relationships, that are vulnerable to fortune. I show that (...) both responses, in different ways, depend on the presupposition that the sense of our promises to love is dependent on our ability to make predictions. The philosophers I discuss assume an epistemological standpoint from which we may attempt to judge whether it is in our general interest to love. I argue that embracing such a perspective by itself leads our attention away from the kind of personal and moral engagement in other people of which our promises to love are expressive. From the perspective of love, the attempt to calculate the risks and gains of loving itself appears as a moral failure to be present to the reality of other people. (shrink)

This study aims to analyze what drives and prevents the purchasing of eco-friendly products across different consumer groups and develops a conceptual model embracing the positive altruistic, positive ego-centric, and negative ego-centric antecedents of eco-friendly product purchase intention and behavior. We empirically validate the conceptual model for green and non-green consumers. Data are analyzed using structural equation modeling and multi-group analysis of the two groups. The results confirm the relevance of the determining factors in the model and show significant differences (...) in eco-friendly product purchasing patterns between green and non-green consumers. Altruistic motives are more important for green than for non-green consumers. Negative ego-centric motives affect the purchase intentions of non-green consumers more than the intentions of green consumers, whereas the impact of negative motives on behavior is stronger for green than for non-green consumers. The first contribution of this paper is the development and testing of a parsimonious model of eco-friendly products purchasing that embraces both positive and negative antecedents, which have been theoretically suggested in the past but have rarely been empirically tested together. The second contribution of this study is that it develops insight into the specific antecedents of eco-friendly products purchasing for green and non-green consumers to assess potential similarities and differences in eco-friendly products purchasing process, the hypothesized antecedents, their impact on eco-friendly products purchase intention and behavior, and the intention–behavior relation.

In most countries in the global north, social differences in health status and disease prevalence and outcomes are persistent and growing. This is also the case in the welfare states of Scandinavia. In Denmark, the empirical point of departure for this article, income inequality is relatively low and social mobility is generally considered to be high. One of the ideals of the Danish welfare state is that all citizens have free and open access to the tax-funded health-care system. All Danish (...) citizens can register at a general practice, which serves as the gatekeeper for more specialized health-care... (shrink)

One of the standard examples in contemporary moral psychology originates in the works of social psychologist Jonathan Haidt. He treats people's responses to the story of Julie and Mark, two siblings who decide to have casual, consensual, protected sex, as facts of human morality, providing evidence for his social intuitionist approach to moral judgements. We argue that Haidt's description of the facts of the story and the reactions of the respondents as ‘morally dumbfounded’ presupposes a view about moral reasoning that (...) is more substantial than he acknowledges. Drawing on the philosophical work by Iris Murdoch and Cora Diamond, we explore how different descriptions of human morality, sexuality, and family relations engage us in evaluations about distinctive features of human life and language that go deeper than Haidt envisages. Thus, we show the need to attend to the concepts used to describe the facts of human moral psychology and the pictures of morality these concepts reveal about the researcher's own understanding of moral experience. This points to the particular responsibility any researcher into human moral psychology has for ensuring that the descriptions they offer are attuned to the complexities of the lives of those they form theories about and that these do not appear conceptually confounding.

What does a lover mean when he says, ‘You're the most beautiful girl in the world’?

In order to articulate an account of erotic love that does not attempt to transcend its personal features, Robert Solomon and Martha Nussbaum lean on the speeches by Aristophanes and Alcibiades in Plato’s Symposium. This leads them to downplay the sense in which love is not only for another person, but also for the good. Drawing on a distinction between relative and absolute senses of speaking about the good, I mediate between two features of love that at first may seem (...) irreconcilable. The first is the sense in which love is deeply personal in character. The second is the sense in which we in love come to articulate ethical demands. With the help of the Diotimian ascent of love that Socrates presents in his speech, I submit that these two can come together in the realization that our personally conditioned responses in love are transformed to accommodate demands that carry an unconditional meaning.

Negative conditional stimulus valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person was paired with an aversive US, while another was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the CS− (...) poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS−. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding. (shrink)

Are there reasons for loving? How can I promise to love someone? Is there such a thing as unconditional love? Am I responsible for loving or for failing to love someone? Can there be love without idealization? -/- This work sets out to show that many of the questions we raise when philosophizing about love are expressive of confusions about what we talk about when we talk about love. Addressing questions pertaining to philosophical discussions about emotions, personal identity and the (...) meaning of language and morality, the author shows how these confusions can be dissolved by carefully attending to our different conversations about love. Her investigations show that many of the challenges we face when reflecting on love do not have the kind of scientific or strictly philosophical character that would allow us to settle them once and for all. They are moral in character and gain their significance from the questions they raise about the place love has in our own lives. The kind of reflection on the meaning of love suggested in this work does not depend on any new discoveries about the phenomena of love. It is available to anyone who is prepared to reflect on our ways of speaking and to question our preconceptions of love and of philosophy. Through such reflection our understanding of love may continually deepen. (shrink)

Among the beliefs Wittgenstein holds that cannot be taken to be true or false, but rather appear to him as certain, are "all human beings have parents" (On Certainty §240): "I believe that I have forebears and that every human being has them" (OC §240) and "I have a father and a mother" (OC §282). I ask what moral questions are entailed in thinking of the changes that our current Western conceptual landscape has undergone in relation to parenthood and family (...) life in the light of the growing rights and recognition of sexual and gendered minorities. What is changing when we start to think of sentences such as "Everyone has a father and a mother" as not expressing an indubitable truth, a fundamental fact of our existence, but as constituting an oppressive social norm? What has already changed in our ways of conceiving of ourselves when we stop regarding such ways of expressing ourselves as a necessary aspect of our natural history but start thinking of them as one possibility among others in finding good and meaningful forms of life? What aspects remain unquestionable in Wittgenstein's beliefs throughout these changes, and what aspects of our family ties would we do best not to let slide? (shrink)

Questa ricerca, attraverso alcune letture incrociate di Michel Foucault e di Claude Lévi-Strauss, mette in luce l’attualità di due grandi pensatori che pongono al centro delle loro teorie il tema della distanza, dell’altro da sé e del ritorno a sé per comprendere il ruolo del soggetto nella civiltà occidentale. Al di là delle rilevanti differenze che li contraddistinguono, Foucault e Lévi-Strauss percorrono due cammini teorici volti a decostruire il rapporto tra verità e soggetto nella civiltà occidentale adottando una prospettiva della (...) distanza e dell’allontanamento da sé, quali tecniche per comprendere se stessi. Da una parte il concetto foucaultiano di eterotopia, in quanto «spazio assolutamente altro», permette di comprendere i meccanismi attraverso i quali ci si proietta in un altrove senza luogo preciso per localizzare se stessi. Il campo dell’etnologia, sarà dunque letto attraverso la lente foucaultiana, quale «eterotopologia», o scienza eterotopica, per eccellenza. Dall’altra, questo concetto sarà analizzato alla luce di quello che Lévi-Strauss ha definito nel saggio sui Tre umanesimi una «tecnica dello straniamento», ovvero un metodo che permette di pensare se stessi grazie al confronto con l’Altro, con culture di altri luoghi ed altri tempi: per conoscere il soggetto che è l’uomo, non si può non prescindere da un lavoro di continui raffronti e paragoni tra diverse società nel tempo e nello spazio.

This is the first book to unpack the legal and ethical issues surrounding unauthorised intimate examinations during labour. The book uses feminist, socio-legal and philosophical tools to explore the issues of power, vulnerability and autonomy. The collection challenges the perception that the law adequately addresses different manifestations of unauthorised medical touch through the lens of women's experiences of unauthorised vaginal examinations during labour. The book unearths several broader themes that are of huge significance to lawyers and healthcare professionals such as (...) the legal status of women and their bodies. The book raises questions about women's experiences during childbirth in hospital settings. It explores the status of women's bodies during labour and childbirth where too easily they become objectified, and it raises important issues around consent. The book highlights links to the law on sexual offences and women's loss of power under the medical gaze. The book includes contributions from leading feminist philosophers, medical professionals, and academics in medicine and law, and offers pioneering analysis relevant to lawyers and healthcare professionals with an interest in medical law and ethics; feminist theory; criminal law; tort law; and human rights law.

When it comes to the relationship between art and nature, research on Adorno’s aesthetics usually centres on his discussion of Kant and Hegel. While this reflects Adorno’s own position – his comprehension of this relationship is to a large extent developed through a critical re-reading of both the Kantian and the Hegelian position – I argue that we are able to gain important insights into Adorno’s aesthetics and the central art–nature relation by reading his ideas in the light of Schelling’s (...) conception of this relationship. The article focuses on the similarities between Schelling’s notion of nature’s productivity and Adorno’s understanding of natural beauty. It concludes with a discussion on Adorno’s re-evaluation of the reconciliatory power of the exemplary unity of the artwork in conjunction with Schelling’s comparison between artwork and organism, as well as his concept of the construction of nature.

Recent work on workplace narratives as a site for the discursive construction of professional identities has focused on speakers who can be considered experienced and knowledgeable experts in their fields. The present study, in contrast, explores two types of workplace narratives — reflective and relational narratives — produced by a group of professionals who are non-experts: in this case, novice language teachers. Specifically, the article illustrates how the moral stance that a novice constructs within a narrative may be formulated in (...) uncertain terms, may be destabilized by the primary narrator, or may be subject to revision by other participants. Finally, the study highlights the relationship between the narrative dimensions of moral stance and tellership, and suggests that participant structure, participants' role relationships, and institutional power asymmetry are especially relevant factors to consider in any further analyses of novices' workplace narratives.

The social intuitionist approach to moral judgments advanced by social psychologist Jonathan Haidt presupposes that it is possible to provide an explanation of the human moral sense without normative implications. By contrast, Iris Murdoch’s philosophical work on moral psychology suggests that every description of morality necessarily involves evaluative features that reveal the thinker’s own moral attitudes and implicit philosophical pictures. In the light of this, we contend that Haidt’s treatment of the story about Julie and Mark, two siblings who decide (...) to have casual, protected, and in his view harmless sex, provides a too simplistic picture of what is involved in understanding human morality. Despite his aim to explain the roots of moral judgments, he fails to provide a deeper understanding of morality in two different respects. First, he does so by suggesting that his story contains all the relevant information needed to take a moral stand on it, and by rejecting as irrelevant the wider human context in which questions about sexual and family relations arise. Second, he simplifies the responses of the people who are subject to his experiment by disregarding their various reasons for disapproving and by equating understanding human morality with explaining an impersonal psychological process.

Engaging with the philosophical writings of Iris Murdoch, we submit that there are difficulties associated with providing a good description of morality that are intimately connected with difficulties in understanding other human beings. We suggest three senses in which moral philosophical reflection needs to account for our understanding of others: (1) the failure to understand someone is not merely an intellectual failure, but also engages us morally; (2) the moral question of understanding is not limited to the extent to which (...) we understand a particular person, but also presents itself in how we picture difficulties in understanding people; and (3) “philosophical pictures of morality” fundamentally shape the conceptual framework we use to investigate morality, as well as the analysis of morality we find illuminative and satisfactory. Exploring the implications of these claims, we ask what it means to think of others as the same, or as different, from ourselves. We then consider the ethical significance of finding, or not finding, our feet in our encounters with others, dwelling on how the metaphor of movement reveals one way in which we are never at peace in the exploration of morality.

Dieser Band lotet vor dem Hintergrund einer krisenhaften Gegenwart das Verhältnis von Verletzbarkeit und Institutionen aus. Im Fokus stehen dabei die Fragen, wie Dimensionen der Verletzbarkeit durch Anrufungen und soziale, politische, kulturelle Praktiken (doing vulnerability) institutionell hergestellt und perpetuiert werden, in welchen Bedeutungszusammenhängen sie verankert und verstetigt sind und wie Anrufungen der Verletzbarkeit schließlich auch provoziert und subvertiert werden können. Institutionen werden dabei nicht als homogene Gebilde, sondern als Bündelung von Kräften verstanden, die es immer wieder neu zu entwerfen, zu (...) imaginieren, zu erstreiten und zu verteidigen gilt.

This paper examines Kahneman and Tversky’s standard explanation for preference reversal due to framing effects in the famous “Asian flu” case. It argues that, alongside with their “loss/no gain effect” account, an alternative interpretation, still consistent with the empirical data, amounts to a more reasonable psychological explanation for the preference reversal. Specifically, my hypothesis is that shifts in the baseline induce shifts in the agents’ classification of the same action as “doing harm” rather than “allowing harm to occur”, and that (...) people are risk-seeking when it comes to avoid causing extra deaths–doing harm–and risk-averse when it comes to preventing more deaths–by the means of allowing other deaths to occur as a side effect. I then survey the two most influential concurrent accounts in the moral literature, with respect to the relation between the loss/no gain and the doing/allowing distinction: Horowitz’s reductionist conclusion, which argues that the latter collapses into the former, and Kamm’s rebuttal, which claims instead that the two distinctions can be pulled apart. I eventually explain why my interpretation differs from both these positions. (shrink)
