Learning in educational settings most often emphasizes declarative and procedural knowledge. Studies of expertise, however, point to other, equally important components of learning, especially improvements produced by experience in the extraction of information: Perceptual learning. Here we describe research that combines principles of perceptual learning with computer technology to address persistent difficulties in mathematics learning. We report three experiments in which we developed and tested perceptual learning modules to address issues of structure extraction and fluency in relation to algebra and (...) fractions. PLMs focus students’ learning on recognizing and discriminating, or mapping key structures across different representations or transformations. Results showed significant and persisting learning gains for students using PLMs. PLM technology offers promise for addressing neglected components of learning: Pattern recognition, structural intuition, and fluency. Using PLMs as a complement to other modes of instruction may allow students to overcome chronic problems in learning. (shrink)

Aggleton & Brown have built a convincing case that hippocampus-related circuits may be involved in thalamic amnesia. It remains to be established, however, that their model represents a distinct neurological system, that the distinction between recall and familiarity captures the roles of these pathways in episodic memory, or that there are no other systems that contribute to the signs of amnesia associated with thalamic disease.

In lieu of an abstract, here is a brief excerpt of the content:Rhetoricians Identified:A Call to Interdisciplinary Action and How it Resonated in the Field of RhetoricChristine Isager and Sine Nørholm Just"I actually like this book a lot, but I am not sure how comfortable I am with liking it," wrote William Keith (1995, 488) in a review of the original 1993 edition of Steve Fuller's Philosophy, Rhetoric, and the End of Knowledge (PREK), in which rhetoric is invited to participate (...) in the interdisciplinary reconfiguration of Science and Technology Studies (STS). This hesitant enthusiasm aptly exemplifies how an interdisciplinary invitation is likely to make its addressees squirm as they watch their professional aims being defined and then redefined by a disciplinary outsider who points out a place for them in a novel disciplinary constellation. Moreover, and more specifically, Keith's comment exemplifies how PREK was received by rhetoricians. On the surface, the reviews were glowing. In Philosophy and Rhetoric as well as in Philosophy of the Social Sciences, Keith expressed certain doubts about Fuller's work, but still he described it as "important," "exceptional," "superb" (1996; 1995). In the Quarterly Journal of Speech, Kenneth S. Zagacki called PREK both "excellent" and "exciting" (1995), and he was backed by John Angus Campbell and Keith R. Benson a year later when the same journal included PREK in an omnibus review entitled "The Rhetorical Turn in Science Studies" (Campbell and Benson 1996). Like Alan Gross, who reviewed the book in College English together with a number of works on workplace writing (1994), Campbell and Benson placed PREK at the cutting edge of rhetorical theory.The initial excitement over PREK forms a sharp contrast to the quite negligible impact that the book has had on the field of rhetoric in the decade that has passed since it was first published. In this essay we will undertake a close reading of the book along with the five above-mentioned reviews, looking for an explanation of the peculiar fate that met Steve [End Page 248] Fuller's proposal in the rhetorical disciplinary context. Our conclusion is that on reading the book, rhetoricians felt so flattered by Fuller's confident handling of rhetoric that the task of introducing and applying rhetorical theory in STS seemed, on the whole, to have been done for them. Furthermore, Fuller's attempts to construct a rhetorical agency are subverted by his idiosyncratic, i.e., inimitable, professional approach, which is also reflected in his style of writing. At once presumptuous and colloquial, his rhetoric serves to impress and entertain, but it fails to engage his audience substantially and to enact the interpenetrative stance that was intended to be the hallmark of PREK and that continues to be the commendable chief concern of Steve Fuller and his fellow social epistemologists.Text-Intertext and IdentificationInterdisciplinary invitations or, rather, interdisciplinary inspirational works of science were originally described as a noteworthy rhetorical genre by Leah Ceccarelli (2001). Ceccarelli explores how claims to scientific unity have handled a primary constraint: their multiple audiences. Fuller explicitly positions PREK within the genre of interdisciplinary inspiration by asserting that "the success of this book... should be measured in terms of its ability to persuade philosophers, theoretical humanists and social scientists, STS practitioners, and rhetoricians of science to see each other as engaged in a common enterprise" (1993, xii-xiii). We will not, however, be examining PREK's ability to be strategically opaque (as Fuller puts it), polysemous(Ceccarelli's term), or otherwise adapted to address its multiple audiences. Instead, we focus solely on Fuller's address to rhetoricians and study how he identifies with this particular audience. Ceccarelli recognizes the importance of ethical appeal in interdisciplinary invitations by positing the establishment of both an authoritative and personal authorial persona as a generic criterion. We follow this lead and add a Burkean emphasis on identification.According to Kenneth Burke, identification is a prior condition for persuasion "precisely because there is division" (Burke 1969, 22). The speaker's success depends on his ability to imitate the ways of his audience and to create a common ground or perspective that makes collective action possible. Burke's work allows us to distinguish three rhetorical strategies of identification. The first strategy... (shrink)

Sound moves us. Nowhere is this more apparent than in our responses to genuine emotional vocalizations, be they heartfelt distress cries or raucous laughter. Here, we present perceptual ratings and a description of a freely available, large database of natural affective vocal sounds from human infants, adults and domestic animals, the Oxford Vocal (OxVoc) Sounds database. This database consists of 173 non-verbal sounds expressing a range of happy, sad, and neutral emotional states. Ratings are presented for the sounds on a (...) range of dimensions from a number of independent participant samples. Perceptions related to valence, including distress, vocalizer mood, and listener mood are presented in Study 1. Perceptions of the arousal of the sound, listener motivation to respond and valence (positive, negative) are presented in Study 2. Perceptions of the emotional content of the stimuli in both Study 1 and 2 were consistent with the predefined categories (e.g., laugh stimuli perceived as positive). While the adult vocalizations received more extreme valence ratings, rated motivation to respond to the sounds was highest for the infant sounds. The major advantages of this database are the inclusion of vocalizations from naturalistic situations, which represent genuine expressions of emotion, and the inclusion of vocalizations from animals and infants, providing comparison stimuli for use in cross-species and developmental studies. The associated website provides a detailed description of the physical properties of each sound stimulus along with cross-category descriptions. (shrink)

Recent research has begun to explore individual differences in statistical learning, and how those differences may be related to other cognitive abilities, particularly their effects on language learning. In this research, we explored a different type of relationship between language learning and statistical learning: the possibility that learning a new language may also influence statistical learning by changing the regularities to which learners are sensitive. We tested two groups of participants, Mandarin Learners and Naïve Controls, at two time points, 6 (...) months apart. At each time point, participants performed two different statistical learning tasks: an artificial tonal language statistical learning task and a visual statistical learning task. Only the Mandarin-learning group showed significant improvement on the linguistic task, whereas both groups improved equally on the visual task. These results support the view that there are multiple influences on statistical learning. Domain-relevant experiences may affect the regularities that learners can discover when presented with novel stimuli. (shrink)

Perhaps no other single moral issue today is as hotly contested, or as divisive, as sexuality. Offering a bold and hopeful vision of how Christians - and all people of goodwill - can view this explosive topic, ethicist Christine Gudorf proposes nothing less than a sweeping challenge to traditional Christian teaching on sexual roles, activities, and relationships. Deftly drawing on Scripture, natural law, historical and contemporary Catholic and Protestant theology, the social sciences, and, significantly, the lived experiences of today's (...) women and men, Gudorf presents a carefully crafted and systematic reconstruction of Christian sexual ethics. Her aim, above all, is to engender appreciation, not rejection and shame, of our bodies and our sexuality. Contending that body, sex, and pleasure are divine gifts revealing God's grace, Gudorf emphasizes the need to understand sexual desire as a positive good, a source of love and commitment. She further explores the relationship between sexuality and reproduction, arguing that "procreationism" - the assumption that the sole aim and ultimate end of sexuality must always be offspring - is unjust and oppressive. Written with insight, clarity, and compassion, Body, Sex, and Pleasure is a provocative and compelling call to all women and men to reject the damaging influence of body/soul dualism - and, ultimately, to do justice to the Incarnation, the central revelations of Scripture, and human dignity.

The personal writings of First World War nurses and VADs (volunteers) provide the historian with a range of insights into the war and women's nursing roles within it. This paper offers a number of methodological perspectives on these writings. In particular, it emphasises two elements of engagement with texts that can act as important influences on subsequent historical writings: authorial intention and scholarly interpretation. In considering the interplay of these two elements, the paper emphasises the motivations both of those who (...) produced primary sources and of those who later used them to ‘serve’ particular historical interpretations. The paper examines letters, diaries and semi‐fictional writings, considering the influences of gender, class and professional background on the ways in which their authors wrote. It then briefly considers the uses to which historians have put these original writings. The paper offers insights into the ways in which complex personal writings can be interpreted and concludes that the writings of First World War nurses and volunteers offer a rich and varied set of perspectives on both the war itself and the nature of wartime nursing work.

Graphical AbstractMuch contemporary behavioral science stops short of considering the ethical implications of its own findings. This generates a contradiction between methods and discoveries, and hinders translation between updated scientific evidence for animal sentience and corresponding political and legal changes. A recent and particularly illustrative example in rodents is described here.

This article draws on data from various sources for 190 developed and developing nations and uses them to examine gender regimes, or forms of patriarchal structures, at the regional level. I argue for multiple, rather than single, measures of gender inequality and illustrate that using many inequality measures exposes a wider range of outcomes within the Global South than the North, also suggesting the inefficacy of this geographic dichotomy. Then I re-examine the outcomes with nations grouped into seven regions, showing (...) that each region has different variables that define their gender inequalities. Finally, I link gendered social institutions and implicitly gendered political-economic structures to gender-inequitable outcomes in six regions to reveal three different gender regimes across the regions.

This article argues that the condition of women in Third World societies cannot be separated from the colonial experience since the power relationships that were established during the colonial era between Europe and its territories, and between women and men, have not varied significantly and are still recreated through contemporary mechanisms. For example, development projects promoted by Western countries to modernize the Third World have, in the long run, better served their own interests than those of their intended beneficiaries. As (...) a result and contrary to expectations, growth and prosperity still elude the Third World. We also show that during the current international economic crisis, women's unpaid or underpaid labor has become the basis of new development programs and policies and is crucial to the recent phase of capitalist development. We discuss how the structural position and status of women and colonies closely resemble each other and have served as the foundations of the capital accumulation process and the development of industrial nations. The concept of women as a last colony thus becomes a compelling metaphor of liberation and leads us to stress the need for a worldwide process of gender decolonization, entailing the reformulation of power relations between women and men.

The women's silence in response to the message of the “young man” at the tomb is a feature found only in Mark. Its omission by Matthew and Luke suggests that they found this element in the narrative problematic. Yet Mark's text has played a significant role in the Easter liturgy of the ancient church and beyond. The reception history of the narrative reveals both harmonization and discord.

Although robust sex differences are abundant in men and women’s mating psychology, there is a considerable degree of overlap between the two as well. In an effort to understand where and when this overlap exists, the current study provides an exploration of within-sex variation in women’s mate preferences. We hypothesized that women’s intelligence, given an environment where women can use that intelligence to attain educational and career opportunities, would be: (1) positively related to their willingness to engage in short-term sexual (...) relationships, (2) negatively related to their desire for qualities in a partner that indicated wealth and status, and (3) negatively related to their endorsement of traditional gender roles in romantic relationships. These predictions were supported. Results suggest that intelligence may be one important individual difference influencing women’s mate preferences. (shrink)

This article explores the meanings of social class for American women who have experienced downward mobility after divorce. These women experienced social class as a process of negotiation, and subjective elements often predominated over objective criteria. However, serious changes in their material reality subsequently forced redefinition of class identity. While divorced women sometimes identify with other women in the same situation, this identification is often mitigated by the effects of stigma and cognitive processes of differentiation, inhibiting the development of a (...) collective group identity. Theoretically, the study showed that social class identity needs to be seen as changing over time, at times existing in a state of conflict between subjective identification and objective economic status, rather than as a neatly resolved or static social identity.

Feminists look critically at any infliction of pain on others, usually requiring that it be consensual, and often both consensual and for the benefit of the person afflicted. Most torture of women is not recognized under official definitions of torture because it is not performed by or with the consent of (government) officials. Women are, however, also victims of torture under official definitions as military or civilian prisoners or as members of defeated populations in war, and are more often subjected (...) to sexual torture, which until recently has not been understood either as torture or even a war crime. Rape, especially serial gang rape, it is argued, should be understood as torture, as the essence of torture is the use of severe pain to obscure or obliterate the victim's sense of agency. (shrink)

Because critics of liberation theology have failed to note the existence of alternative contexts for doing theology, they do not recognize alternative ways of testing theological truth.

Though it is often taken for granted that feminists necessarily must condemn the exclusion of women from the Roman Catholic priesthood, the author demonstrates that the "politics of difference," if pursued consistently, reopens this question. International feminist arguments for honoring gender differences, the teachings of John Paul II concerning women, and Catholic social justice teachings, taken jointly, suggest that the current Catholic exclusion of women from the priesthood is unjust not because the reservation of a social role to a single (...) sex is inherently unacceptable, but because of the asymmetry in power between the roles accorded men and women in the governance of the Catholic Church. To be just, sex-specific reservation of roles must meet the criteria of balance, proportion, power, and particularity. (shrink)

THIS ESSAY EXAMINES GLOBAL WATER PRIVATIZATION EFFORTS IN LIGHT of the environmental teachings of both Islam and Christianity, proposing that although environmental ethics is more developed within Christianity, Islam offers more ethical sources for thinking about water due to the arid climate in which Islam developed. Furthermore, this essay advocates full-cost pricing as necessary to attain closed loop water recycling, maintains that full-cost pricing does not further disadvantage the poor, and argues that full-cost pricing more easily fits Muslim and Christian (...) moral imperatives than present water policies do.

Many male traits are well explained by sexual selection theory as adaptations to mating competition and mate choice, whereas no unifying theory explains traits expressed more in females. Anne Campbell's “staying alive” theory proposed that human females produce stronger self-protective reactions than males to aggressive threats because self-protection tends to have higher fitness value for females than males. We examined whether Campbell's theory has more general applicability by considering whether human females respond with greater self-protectiveness than males to other threats (...) beyond aggression. We searched the literature for physiological, behavioral, and emotional responses to major physical and social threats, and found consistent support for females' responding with greater self-protectiveness than males. Females mount stronger immune responses to many pathogens; experience a lower threshold to detect, and lesser tolerance of, pain; awaken more frequently at night; express greater concern about physically dangerous stimuli; exert more effort to avoid social conflicts; exhibit a personality style more focused on life's dangers; react to threats with greater fear, disgust, and sadness; and develop more threat-based clinical conditions than males. Our findings suggest that in relation to threat, human females have relatively heightened protective reactions compared to males. The pervasiveness of this result across multiple domains suggests that general mechanisms might exist underlying females' unique adaptations. An understanding of such processes would enhance knowledge of female health and well-being. (shrink)
