On the categorization of admired and disliked exemplars of admired and disliked racial groups

The present work examined the influence of affective fit in the racial categorization process. Study 1 tested whether famous exemplars of stigmatized and nonstigmatized racial groups are categorized by race at differential rates, depending on whether they are admired or disliked. Using an inverted-face paradigm, Study 2 examined whether racial categorization accuracy differs for admired and disliked exemplars of these groups. Study 3 examined the influence of collective self-esteem on Whites' tendency to differentially categorize admired and disliked Black and White exemplars. Last, Study 4 replicated the pattern of results found in the previous studies for White participants, making use of unknown exemplars about whom participants learned either positive or negative information prior to categorizing them. Taken together, the results suggested that phenotypically irrelevant affective information regarding exemplars and their social group memberships influences the racial categorization process. Implications for prejudice and stereotyping are discussed.     

Why do interracial interactions impair executive function? A resource depletion account

Three studies investigated the veracity of a resource depletion account of the impairment of inhibitory task performance after interracial contact. White individuals engaged in either an interracial or same-race interaction, then completed an ostensibly unrelated Stroop color-naming test. In each study, the self-regulatory demands of the interaction were either increased (Study 1) or decreased (Studies 2 and 3). Results revealed that increasing the self-regulatory demands of an interracial interaction led to greater Stroop interference compared with control, whereas reducing self-regulatory demands led to less Stroop interference. Manipulating self-regulatory demands did not affect Stroop performance after same-race interactions. Taken together, the present studies point to resource depletion as the likely mechanism underlying the impairment of cognitive functioning after interracial dyadic interactions.     

Extinction of conditioned odor potentiation of startle

Several recent studies with rats (Sprague-Dawley strain) have documented that an odor previously paired with shock potentiates the acoustic startle response, a phenomenon referred to as conditioned odor potentiation of startle (OPS). A surprising finding in these studies was that OPS did not extinguish even though the odor was present throughout the 25-min test session. Therefore, the present study more fully examined extinction of OPS. The results of Experiment 1, which employed both within-subject and between-group comparisons, showed that extinction of OPS occurred in adult rats only after several days of testing. Experiment 2 used the between-group procedure and found similar results with 23-day-old rats, the youngest age that exhibits the OPS effect. Experiment 2 also showed that giving rats 15 odor-shock pairings at 16 days of age, an age where they acquire the odor-shock association but cannot express it via OPS, does not increase subsequent resistance to extinction following odor-shock pairings at 23 days of age. Taken together, the results of this study show that (1) although OPS is somewhat resistant to extinction, it does extinguish with repeated tests and (2) suggests that there are no age differences in the rate of extinction of OPS.     

Got Pain? Racial Bias in Perceptions of Pain

In the days of slavery, White people assumed that Black people felt less pain than did White people. This belief was used to justify slavery; it was also used to justify the inhumane treatment of Black men and women in medical research. Today, White Americans continue to believe that Black people feel less pain than do White people although this belief has changed from its historical, explicitly racist form. Racial attitudes do not moderate the bias, suggesting that racial bias in perceptions of others' pain is not rooted (solely) in racial prejudice. Moreover, Black Americans too believe that Black people feel less pain than do White people, suggesting that the bias is no longer grounded in intergroup dynamics. Rather, contemporary forms of this bias stem from assumptions that Black people face more hardship and “thus” can withstand more pain and assumptions that Black people's bodies are not only different but also superhuman. Although this new instantiation of the pain perception bias is decidedly more “benevolent”, it can nonetheless lead to negative outcomes. Here, we consider how racial bias in perceptions of others' pain may affect racial disparities in health care and intergroup relations more generally. We also discuss potential avenues for interventions aimed at preventing this bias among children and reducing this bias among adults.     

Botswana school child parents: their personal and community relationships contexts for counselling

The study determined personal-socio-contextual influences that predicted the perceived quality of relationships with Batswana early teenage mothers. The participants were 86 Botswana high school students (mean age 18.97, SD = 1.76) with motherhood. They completed a numerical measure of adjustment to teenage motherhood in the context of family, school and community and also culture and social policy. A proportion of the teenagers (10%) participated in focus group discussion on the same aspects. The quantitative data were analysed to predict family, interpersonal, school and community interpersonal relationships from the teenage mothers' age, age of parents and living arrangements. The qualitative focus group discussion data were thematically analysed. Findings suggest that supportive living arrangements were instrumental to perceived quality of interpersonal relationships in the family and the school and community relationships. Gendered roles of the parents were social capital for family and school and community relationships with teenage-hood. Living arrangements and parental social discounting qualities reliably predicted teen mothers' social outcomes important for early parenthood counselling.     

A New Interpretation of the Weighted Kappa Coefficients

Reliability and agreement studies are of paramount importance. They do contribute to the quality of studies by providing information about the amount of error inherent to any diagnosis, score or measurement. Guidelines for reporting reliability and agreement studies were recently provided. While the use of the kappa-like family is advised for categorical and ordinal scales, no further guideline in the choice of a weighting scheme is given. In the present paper, a new simple and practical interpretation of the linear- and quadratic-weighted kappa coefficients is given. This will help researchers in motivating their choice of a weighting scheme.     

Nuclear Waste Facing the Test of Time: The Case of the French Deep Geological Repository Project

The purpose of this article is to consider the socio-anthropological issues raised by the deep geological repository project for high-level, long-lived nuclear waste. It is based on fieldwork at a candidate site for a deep storage project in eastern France, where an underground laboratory has been studying the feasibility of the project since 1999. A project of this nature, based on the possibility of very long containment (hundreds of thousands of years, if not longer), involves a singular form of time. By linking project performance to geology’s very long timescale, the project attempts “jump” in time, focusing on a far distant future, without understanding it in terms of generations. But these future generations remain measurements of time on the surface, where the issue of remembering or forgetting the repository comes to the fore. The nuclear waste geological storage project raises questions that neither politicians nor scientists, nor civil society, have ever confronted before. This project attempts to address a problem that exists on a very long timescale, which involves our responsibility toward generations in the far future.
