Racial stereotypes and interracial attraction: phenotypic prototypicality and perceived attractiveness of Asians

What does it take to find a member of a different race attractive? In this research, we suggest that for Whites, attraction to Asians may be based, in part, on stereotypes and variations in Asians' racial appearance. Study 1 reveals that Asians are stereotyped as being more feminine and less masculine than other racial groups-characteristics considered appealing for women but not for men to possess. Study 2 examines how variation in racial appearance, phenotypic prototypicality (PP), shapes the degree to which Asians are gender stereotyped and how PP relates to perceptions of attractiveness. Higher PP Asian men are perceived as being less masculine and less physically attractive than lower PP Asian men. These findings inform theory on how within-group variation in racial appearance affects stereotyping and other social outcomes.     

Searching for Happiness: The Importance of Social Capital

After four decades of research, scholars of happiness continue to debate its causes. While it is generally agreed that a combination of internal and external factors play a role, predicting happiness well remains a challenge. Recent research has proposed that social capital may be a vital factor that has been overlooked. This paper attempts to address that omission. According to Coleman’s (1988) seminal work, three dimensions of social capital exist: (1) trust and obligations, (2) information channels, and (3) norms and sanctions. Using bootstrap hierarchical regression on data from the Canadian General Social Survey of Social Engagement Cycle 17 (2003), we identified blocks of social capital variables described by Coleman, as well as an additional factor of belongingness. Even after controlling for major demographic and individual characteristics, the majority of these blocks show significant relationships with happiness. Our findings support social capital as an important piece in predicting happiness.     

Property rights and the resolution of social conflict

It has long been argued that ownership depends upon social groups' establishing and adhering to rights such as the right to use and to exclude others from using one's own property. The authors consider the application of such rights in the interactions of young peers and siblings, and the extent to which parents support their children in establishing and maintaining the entitlement of owners. They show that children, but not their parents, give priority to ownership in settling property disputes, and argue that diverging models of children's relationships account for these differing perspectives of children and parents.     

Immune stress in late pregnant rats decreases length of gestation and fecundity, and alters later cognitive and affective behaviour of surviving pre-adolescent offspring

Immune challenge during pregnancy is associated with preterm birth and poor perinatal development. The mechanisms of these effects are not known. 5α-Pregnan-3α-ol-20-one (3α,5α-THP), the neuroactive metabolite of progesterone, is critical for neurodevelopment and stress responses, and can influence cognition and affective behaviours. To develop an immune challenge model of preterm birth, pregnant Long-Evans rat dams were administered lipopolysaccharide [LPS; 30?μg/kg/ml, intraperitoneal (IP)], interleukin-1β (IL-1β; 1?μg/rat, IP) or vehicle (0.9% saline, IP) daily on gestational days 17-21. Compared to control treatment, prenatal LPS or IL-1β reduced gestational length and the number of viable pups born. At 28-30 days of age, male and female offspring of mothers exposed to prenatal IL-1β had reduced cognitive performance in the object recognition task compared to controls. In females, but not males, prenatal IL-1β reduced anxiety-like behaviour, indicated by entries to the centre of an open field. In the hippocampus, progesterone turnover to its 5α-reduced metabolites was lower in prenatally exposed IL-1β female, but not in male offspring. IL-1β-exposed males and females had reduced oestradiol content in hippocampus, medial prefrontal cortex and diencephalon compared to controls. Thus, immune stress during late pregnancy reduced gestational length and negatively impacted birth outcomes, hippocampal function and central neurosteroid formation in the offspring.     

Genetic Counseling in a Busy Pediatric Metabolic Practice

Patients with inborn errors of metabolism and their families require unique clinical care including management of acute illnesses, screening for long term complications, discussion of the etiology of the condition, connections to social supports, and clarification of the recurrence risks and prenatal testing and treatment options. Our multidisciplinary pediatric metabolic clinic combines the skills of metabolic geneticists, pediatric dieticians, social workers, clinical pharmacists, nurses and genetic counselors to provide optimal and well-rounded care for our patients and their families. Given the inherited nature of most inborn errors of metabolism and the necessary long-term management for these disorders, the genetic counselor’s role in this clinic setting is integral in providing ongoing support and education for patients and their families. This includes coping with the disease burden, helping patients and families adapt to a condition in the family and ensuring adequate understanding of the genetic risks and the available prenatal diagnostic and reproductive choices. Our clinic provides services to a large geographic area with many isolated populations where unique metabolic diseases are highly prevalent secondary to a founder effect. In this paper, we share our experience in providing longitudinal care to children with complex medical needs due to metabolic disorders and highlight the role of the genetic counselor in this clinic setting.     

Breast and Ovarian Cancer: The Forgotten Paternal Contribution

Five to 10% of all cases of breast and ovarian cancer are attributed to a heritable genetic predisposition. Transmission of BRCA1 and BRCA2 mutations is equally likely through maternal or paternal lineage; however, fewer referrals to cancer genetics clinics appear to be made for a paternal, than maternal, family history of breast and/or ovarian cancer. To examine this potential bias, a retrospective review of 315 patient and family charts was conducted by one familial cancer clinic in Toronto, Canada. Referral letters, risk estimates, and family histories were analyzed to identify significant differences between patients referred with maternal and paternal family histories. It was determined that patients are approximately five times more likely to be referred with a maternal family history of breast and/or ovarian cancer as compared to those with a paternal family history (p = <.0001). Individuals with a paternal family history were found to have a different, and higher, pattern of risk estimates (p = .00064). No significant difference was seen between the type of referrals sent by general practitioners, oncologists, and gynecologists. Recommendations to increase the awareness of paternal family history in assessing cancer risk are provided.     

Personality Traits Associated with Genetic Counselor Compassion Fatigue: The Roles of Dispositional Optimism and Locus of Control

Compassion fatigue (CMF) arises as a consequence of secondary exposure to distress and can be elevated in some health practitioners. Locus of control and dispositional optimism are aspects of personality known to influence coping style. To investigate whether these personality traits influence CMF risk, we surveyed 355 genetic counselors about their CMF, locus of control orientation, and degree of dispositional optimism. Approximately half of respondents reported they experience CMF; 26.6% had considered leaving their job due to CMF symptoms. Mixed-method analyses revealed that genetic counselors having an external locus of control and low optimism were at highest risk for CMF. Those at highest risk experienced moderate-to-high burnout, low-to-moderate compassion satisfaction, and tended to rely on religion/spirituality when coping with stress. CMF risk was not influenced by years in practice, number of genetic counselor colleagues in the workplace, or completion of graduate training in this area. Recommendations for practice and education are outlined.     

Effects of role model deservingness on overcoming performance deficits induced by stereotype threat

Previous research has shown that exposure to successful role models can restore performance that had been impaired by stereotype threat, and that some role models are more effective than others. The present research examined the effects of role model deservingness on women's mathematics test performance after being placed under stereotype threat. In Experiment 1, a woman who attained success by herself (deserved) proved a more effective role model than an equally likable and successful woman whose success was handed to her (not deserved). In Experiment 2, women role models proved more effective at combating stereotype threat when their successes were attributable to internal‐stable (deserved) than external‐unstable (not deserved) causes, an effect that was partially mediated by reduction in extra‐task thinking. The results are seen as having implications for theories of stereotype threat and causal attribution. Copyright © 2010 John Wiley & Sons, Ltd.     

Can 15-month-old infants understand pretence? An investigation using the 'violation-of-expectation' paradigm

Productive tests are unsuitable for measuring infants' earliest understanding of pretence, because performance demands may render infants unable to produce the actions required to pass the test. Recently, Onishi, Baillargeon and Leslie (2007) used the violation-of-expectation (VOE) paradigm as a measure of infants' understanding of others' pretence that is free from such performance demands. They found that 15-month-old infants looked longer at an Unexpected event in which an actor pretended to pour into one cup but pretended to drink from another cup, compared to pretending to pour and drink with the same cup. On this basis, they argued that 15-month-old infants expect others' pretence to be consistent, demonstrating their understanding of others' pretence. However, infants may have responded to expectations they had about familiar action sequences, rather than to pretence per se. To test this hypothesis, the current study firstly replicated Onishi et al.'s results in a sample of 28 typically developing 15-month-old infants, and then added a condition using closely matched real versions of their pretend VOE tasks. It was found that infants looked longer at unexpected events, whether or not the events were real or pretend. It was concluded that 15-month-old infants may look longer at pretend events due to violations of expectations they have about familiar action sequences, rather than because they understand others' pretence behaviour.     

Spending time: The impact of hours worked on work–family conflict

Scholars have long assumed that as workers spend more time at work fewer hours are available for their non-work lives leading to negative effects in both domains, and most studies examining the impact of work hours on work and life domains have supported this viewpoint. However, the majority of these studies have used one-dimensional measures of work–family conflict (WFC) and family–work conflict (FWC) on homogenous samples which included primarily married managers and professionals with children. Further, despite calls to examine non-linear relationships between work hours and WFC and FWC, few studies have done so. This study uses multi-dimensional measures to examine the linear and non-linear (quadratic) effects of work hours on WFC and FWC in a heterogeneous sample and examines the moderating effects of several work and family characteristics on these relationships. The findings indicate that whereas work hours have a linear relationship with WFC, the relationship between work hours and FWC is curvilinear. Managerial support was found to moderate the relationship between work hours and one dimension of FWC. Number of children moderated the relationships between work hours and WFC and another dimension of FWC.
