Thinking about Mutual Influences and Connections across Cultures Relates to More Positive Intergroup Attitudes: An Examination of Polyculturalism

Polyculturalism is an ideology focusing on the many ways that racial and ethnic groups have interacted, exchanged ideas, and influenced each other's cultures throughout history and into the present. In this paper, we first briefly review the introduction of and research on polyculturalism by historians. Then we summarize numerous studies with racially and ethnic diverse college students and adult community members in the United States, which have found that greater endorsement of polyculturalism is significantly associated with more positive racial/ethnic intergroup attitudes (less support for social inequality, greater interest in, appreciation for, and comfort with diversity and differences, greater interest in intergroup contact, and greater support for liberal immigration and affirmative action policies) and lower sexual prejudice (lower affective prejudice toward gay men and lesbians, traditional heterosexism, and denial of discrimination against homosexuals, and more positive attitudes toward gay men and lesbians). We conclude by discussing several future directions of this work.     

Serotonin transporter polymorphism interacts with childhood adversity to predict aspects of impulsivity

The serotonin transporter polymorphism has been linked--often in interaction with environmental adversity--to a variety of outcomes, including affective disorders. This polymorphism is widely viewed as relating to anxiety traits. A different view is that it relates instead to impulsivity (vs. control) in reacting to emotions. In a test of the latter view, 303 students were genotyped on this polymorphism and completed self-reports bearing on impulsive reactions to emotions (including both negative and positive emotions in separate measures), impulsive tendencies that do not stem from emotions, and childhood adversity. The impulsivity measures reflected three latent variables: pervasive influence of feelings, feelings (including positive feelings) triggering action, and failure to carry through on intentions (with no mention of emotion). Interactions between genotype and adversity emerged for both emotion-related aspects of impulsivity. Theoretical implications of the findings are discussed.     

Social Dominance Orientation Relates to Believing Men Should Dominate Sexually, Sexual Self-Efficacy, and Taking Free Female Condoms Among Undergraduate Women and Men

Gendered-based power affects heterosexual relationships, with beliefs in the U.S. prescribing that men dominate women sexually. We draw on social dominance theory to examine whether women??s and men??s level of support for group-based hierarchy (i.e., social dominance orientation; SDO) helps explain gender-based power beliefs and dynamics in heterosexual relationships. We conducted a laboratory study at a Northeastern U.S. university among 357 women and 126 men undergraduates who reported being heterosexual and sexually active, testing three sets of hypotheses. First, as hypothesized, women endorsed SDO and the belief that men should dominate sexually less than men did. Second, as hypothesized, among women and men, SDO was positively correlated with the belief that men should dominate sexually, and negatively correlated with sexual self-efficacy (confidence in sexual situations) and number of female condoms (a woman-controlled source of protection) taken. Third, structural equation modeling, controlling for age, family income, number of sexual partners in the past month, and perceived HIV/AIDS risk, supported the hypothesis that among women and men, the belief that men should dominate sexually mediates SDO??s association with sexual self-efficacy. The hypothesis that the belief that men should dominate sexually mediates SDO??s association with number of female condoms taken was supported for women only. The hypothesis that sexual self-efficacy mediates SDO??s association with number of female condoms taken was not supported. Results suggest SDO influences power beliefs and dynamics in heterosexual relationships. Although female condoms are an important woman-controlled source of protection, power-related beliefs may pose a challenge to their use.     

Do People Comprehend Legal Language in Wills?

This study assessed the ability of laypeople to understand a document that most have read and signed: a last will and testament. We focused on concepts that are frequently included in wills, examined whether understanding can be enhanced by psycholinguistic revisions, and assessed comprehension as a function of age. Participants ages 32 to 89 years read will‐related concepts in (i) their traditional format, (ii) a version revised to increase readability, or (iii) a version in which, in addition to those changes, we explained archaic and legal terms. Results showed that increasing the readability and explaining terms enhanced participants' abilities to apply will‐related concepts to novel fact patterns and to explain their reasoning. We found no age‐related effects on comprehension, consistent with well‐documented findings that processing at the situation level of text comprehension is preserved in older adults. We discuss the implications of these findings and suggest ideas for further research. Copyright © 2012 John Wiley & Sons, Ltd.     

Approach/avoidance in dreams

The influential threat simulation theory (TST) asserts that dreaming yields adaptive advantage by providing a virtual environment in which threat-avoidance may be safely rehearsed. We have previously found the incidence of biologically threatening dreams to be around 20%, with successful threat avoidance occurring in approximately one-fifth of such dreams. TST asserts that threat avoidance is over-represented relative to other possible dream contents. To begin assessing this issue, we contrasted the incidence of 'avoidance' dreams with that of their opposite: 'approach' dreams. Because TST states that the threat-avoidance function is only fully activated in ecologically valid (biologically threatening) contexts, we also performed this contrast for populations living in both high- and low-threat environments. We find that 'approach' dreams are significantly more prevalent across both contexts. We suggest these results are more consistent with the view that dreaming is generated by reward-seeking systems than by fear-conditioning systems, although reward-seeking is clearly not the only factor determining the content of dreams.     

Biological and psychological factors associated with memory function in fibromyalgia syndrome.

Fibromyalgia is a stress-related disorder characterized by chronic pain, memory impairment, and neuroendocrine aberrations. With the hypothesis that biological and psychological symptoms may underlie the cognitive problems, the relative influences of neuroendocrine function and psychological factors on declarative memory were examined among 50 women with fibromyalgia. This within-group analysis controlled for age, education, pain, and relevant medications. Neuroendocrine function and depression had significant independent associations with memory function. Higher log-transformed mean salivary cortisol levels were associated with better performance on both immediate and delayed visual recall and with delayed verbal recall. Depressive symptoms were negatively associated with verbal recall. These findings suggest that a basic disorder of endocrine stress responses may contribute to the cognitive symptoms experienced by fibromyalgia patients.     

CODEPENDENCY, LOSS OF SELF, AND POWER

The feminist critique that codependency and loss of self are related to power was tested in a sample of 122 college women and men in committed relationships. Participants completed two codependency measures, a loss of self scale, and three indices of power: perceived power, use of specific influence strategies, and decision making. Among both women and men, codependency and loss of self were positively related to the use of indirect strategies and negatively related to perceived power, and loss of self was negatively related to use of the direct strategies. Among women alone, codependency was also negatively related to use of direct strategies and loss of self negatively related to decision making. These correlational data provide support for a feminist critique of codependency as related to power; however, gender similarities suggest that the relations between power, loss of self, and codependency hold for college men as well as college women.
