Femininity and fertility in sisters with twin brothers: prenatal androgenization? Cross-sex socialization?

Are sisters of twin brothers behaviorally or physiologically masculinized? Prenatal exposure to their brothers' androgens and postnatal socialization experiences unique to girls growing up with twin brothers might influence their attitudes, pubertal development, and reproductive histories. To investigate, we studied age- and cohort-matched samples of Finnish sisters from same-sex and opposite-sex twin pairs. Using data from two ongoing longitudinal studies of consecutive birth cohorts of Finnish twins, we assessed pubertal development at ages 11 and 14 and endorsement of attitudes associated with femininity at age 16. We also studied fertility in Finnish women from same- and opposite-sex twin pairs born from 1958 through 1971, obtaining information on their child-bearing histories when they were ages 15 to 28. Results of each comparison were unambiguously negative: There was no evidence of differences between sisters from same- and opposite-sex twin pairs, and thus, no evidence of either androgenization or cross-sex socialization.     

Linguistic and nonlinguistic priming in aphasia

Studies of real-time processing in aphasia suggest that linguistic symptoms may be due to deficits in activation dynamics rather than loss of linguistic knowledge. To investigate the domain specificity of such processing deficits, we compared performance by Italian-speaking fluent aphasics, nonfluent aphasics, and normal controls in a linguistic priming task (grammatical gender) with their performance in a color-priming task that requires no verbal mediation. Normal or larger than normal color-priming effects were demonstrated in both aphasic groups. Gender priming did not reach significance in either group, even though the patients displayed above-chance sensitivity to gender class and gender agreement in their accuracy scores. The demonstration of spared gender knowledge despite impaired gender priming underscores the utility of on-line techniques in the study of aphasia. The demonstration of spared color priming suggests that priming deficits in aphasia are either (1) specific to speech and language or (2) specific only to those sensorimotor and attentional processes that language shares with other nonlinguistic systems.     

Atheism in religious clothing? Accounting for atheist interventions in the public sphere

In this paper I review several recent attempts to recast atheism in religious form in Canada, the US and the UK. First, several atheists have argued for the redefinition of atheism as a creed deserving of religious protections from the state. Second, various atheist ‘churches’ have gained publicity in recent years, in part due to their appropriation of the Protestant church format and the rhetoric of religious association. Both of these expressions of atheism stand in marked contradiction to older forms of atheism which emerged in response to (and rejection of) Christianity in the West, and they also stand in contrast to popular forms of atheism today, of the kind espoused by Christopher Hitchens and Richard Dawkins. As a result, the cases reviewed here represent the ways in which contemporary atheist movements constitute several different counterpublics, and they mark a significant change in the state’s acknowledgement of atheism as a positive form of belief.     

Individual‐ and group‐level effects of social identification on workplace bullying

A study of 494 employees nested in workgroups from 19 different organizations revealed group identification to be an important factor influencing work-related bullying at both the individual and the group level. Results show that the more employees identified with their group, the less likely they were victims of bullying, which is in line with previous social identity-based analyses of work stress. More importantly, the higher the average level of group identification in the organization, the lower the odds of being a victim versus not being a victim. The latter effect constituted a genuine context effect. These findings redress a neglect of the social bases of workplace bullying and suggest that bullying needs to be understood within a broader perspective of workgroup identities.     

Are all Socialists Anti-religious? Anti-religiosity and the Socialist Left in 21 Western European Countries (1990–2008)

The political situation in the Soviet Union during the twentieth century has led some to suggest that socialism is some kind of secular religion as opposed to ‘normal’ religion. In modern Europe, however, there have been vibrant Christian socialist movements. This article looks into the different attitudes of socialists towards religion and answers the question whether it is pressure of religious activity or pressure of religious identity that makes socialists resist religion. The results from a multilevel analysis of three waves of the European Values Study (1990–2008) in 21 Western European countries specifically point to an increase in anti-religiosity by socialists in countries marked by Catholic and Orthodox religious identities.     

Positive illusions about a partner’s personality and relationship quality

Previous studies have shown individuals to hold positive biases about their relationships. The present study examined positive illusions about a partner’s specific personality characteristics in relation to relationship quality and personality. Both partners of 120 heterosexual couples participated in the present study, making it possible to examine both partner and actor effects. Results showed that although, in general, individuals did not hold positive illusions about a partner’s specific personality characteristics, positive illusions were positively related to relationship quality. In addition, interesting relations emerged between positive illusions about a partner’s personality and both individuals’ personality and marital duration.     

Is an outgroup member in need a friend indeed? Personal and task‐oriented contact as predictors of intergroup prosocial behavior

Intergroup contact, particularly close personal contact, has been shown to improve intergroup relations, mainly by reducing negative attitudes and emotions toward outgroups. We argue that contact can also increase intergroup prosocial behavior. More specifically, we predict that different forms of contact will differentially impact on prosocial behavior directed at individual outgroup members and outgroups as a whole. Data of two studies (N₁ = 264, N₂ = 185), conducted with workgroups in two organizations, show that personal contact is a better predictor of prosocial behavior directed at individual outgroup members, whereas task‐oriented contact is a better predictor of prosocial behavior directed at an outgroup as a whole. Additionally, Study 2 provides evidence that empathy mediates the path from personal contact to individual‐directed prosocial behavior, whereas reward (but not cost) considerations mediate the path from task‐oriented contact to outgroup‐directed prosocial behavior. Implications for research on intergroup contact and prosocial behavior are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Gesture in the developing brain

Speakers convey meaning not only through words, but also through gestures. Although children are exposed to co-speech gestures from birth, we do not know how the developing brain comes to connect meaning conveyed in gesture with speech. We used functional magnetic resonance imaging (fMRI) to address this question and scanned 8- to 11-year-old children and adults listening to stories accompanied by hand movements, either meaningful co-speech gestures or meaningless self-adaptors. When listening to stories accompanied by both types of hand movement, both children and adults recruited inferior frontal, inferior parietal, and posterior temporal brain regions known to be involved in processing language not accompanied by hand movements. There were, however, age-related differences in activity in posterior superior temporal sulcus (STSp), inferior frontal gyrus, pars triangularis (IFGTr), and posterior middle temporal gyrus (MTGp) regions previously implicated in processing gesture. Both children and adults showed sensitivity to the meaning of hand movements in IFGTr and MTGp, but in different ways. Finally, we found that hand movement meaning modulates interactions between STSp and other posterior temporal and inferior parietal regions for adults, but not for children. These results shed light on the developing neural substrate for understanding meaning contributed by co-speech gesture.
