Perceived norms and social values to capture school culture in elementary and middle school

The current study was designed to gain insights into shifting school culture by examining perceived peer group norms and social values across elementary and middle school grades. Perceived norms were assessed by asking participants (N = 605) to estimate how many grade mates were academically engaged, disengaged, and antisocial. To capture social values, peer nominations were used to assess “coolness” associated with these behaviors. Perceived norms became gradually more negative from fall to spring and across grades four to eight. Whereas academic engagement was socially valued in elementary school, negative social and academic behaviors were valued in middle school. Additionally, improved social status was associated with increased academic engagement in fifth grade, disengagement in seventh and eighth grades, and antisocial behavior in sixth grade. The findings suggest that differences between elementary and middle school cultural norms and values may shed light on negative behavior changes associated with the transition to middle school.     

家庭社会经济地位与青少年未来规划的关系:外向性的调节作用及其性别差异

以山东省济南市、莱州市的935名初二和高一学生为被试, 进行为期一年半的追踪研究, 考察了家庭社会经济地位与青少年的教育规划和职业规划之间的关系, 检验了外向性在其中的调节作用及其性别差异。结果表明:(1)家庭社会经济地位能够显著正向地预测青少年T1和T2时的教育规划以及T1时的职业规划;(2)外向性水平越高, 青少年教育规划和职业规划水平越高, 但是这种预测作用不存在长期性;(3)外向性能够调节家庭社会经济地位与青少年教育规划之间关系, 且这种调节作用存在显著的性别差异;但在家庭社会经济地位与青少年职业规划之间不存调节作用。这表明, 外向性不仅能够直接保护青少年的未来规划, 而且能够抵抗低家庭社会经济地位对个体未来规划的不良影响, 但是这种压力抵抗效应在不同性别、不同未来规划的领域之中存在差异。     

Mapping self-reports of working memory deficits to executive dysfunction in Fragile X Mental Retardation 1 (FMR1) gene premutation carriers asymptomatic for FXTAS

Fragile X Syndrome is a neurodevelopmental disorder that is caused by the silencing of a single gene on the X chromosome, the Fragile X Mental Retardation 1 (FMR1) gene. In recent years, the premutation (“carrier”) status has received considerable attention and there is now an emerging consensus that despite intellectual functioning being within the average range premutation males present with subtle executive function impairments that include poor inhibitory control, working memory deficits, and poor planning skills. The ranges of these skills, although not nearly as severe as seen in the full mutation, nonetheless serve to differentiate males with the premutation from males in the unaffected population. In the present study we extend these findings to suggest that behavioral markers, specifically self-report on the Brown Attention-Deficit Disorder Rating Scales, may serve as a clinically useful indicator or “signature” of the Fragile X Premutation status. We discuss the possibility that this measure provides a means to identify those at greatest risk for developing the newly identified neurodegenerative disorder that affects some premutation males – Fragile X Tremor/Ataxia Syndrome (FXTAS).     

HOW TO CONFUSE ORGANISMS WITH MOUSETRAPS: MACHINE METAPHORS AND INTELLIGENT DESIGN

Why do design arguments—particularly those emphasizing machine metaphors such as “Organisms and/or their parts are machines”—continue to be so convincing to so many people after they have been repeatedly refuted? In this essay I review various interpretations and refutations of design arguments and make a distinction between rationally refuting such arguments (Refuting_R) and rendering them psychologically unconvincing (Refuting_P). Expanding on this distinction, I provide support from recent work on the cognitive power of metaphors and developmental psychological work indicating a basic human propensity toward attributing agency to natural events, to show that design arguments “make sense”unless one is cued to look more closely. As with visual illusions, such as the Müller‐Lyer arrow illusion, there is nothing wrong with a believer's cognitive apparatus any more than with their visual apparatus when they judge the lines in the illusion to be of unequal length. It takes training or a dissonance between design beliefs and other beliefs or experiences to play the role that a ruler does in the visual case. Unless people are cued to “look again” at what initially makes perfect sense, they are not inclined to apply more sophisticated evaluative procedures.

Social Dominance Orientation, Authoritarianism, and Support for Intergroup Violence Between the Middle East and America

Social dominance theory has generally posited that terror and intergroup violence can be explained in terms of social dominance struggles. Social dominance theorists have described terror mostly as a tool for maintaining intergroup hierarchies in society (Sidanius & Pratto, 1999). Although implications of the theory suggest that terror may also be used by lower status groups as a tool for the resistance of domination by higher status groups, this prediction heretofore has not been empirically demonstrated. Data from two samples, one in the United States and one in Lebanon, were collected regarding attitudes toward terrorism and intergroup violence. The results show that the American sample demonstrates the typical patterns of social dominance such that those who are higher in social dominance orientation tend to support greater violence toward the Middle East. However, the Lebanese sample shows the opposite pattern, such that those who are lower in social dominance orientation tend to support violence toward the West. These results suggest that (1) support for terrorism among Middle East citizens is a project of counterdominance, and, more broadly, that (2) the relationship between social dominance orientation and support for violence depends on the dynamics of the conflict and the status of the perpetrators.     

Tomboyism or Lesbianism? Beyond Sex/Gender/Sexual Conflation

To illuminate questions of sex/gender/sexual conflation the researcher focused on the relationship between reported tomboyism and lesbianism. Narratives of childhood and adolescence were collected from 32 women who were grouped into four gender/sexual status combinations: “lesbian/bisexual butch,” “straight butch,” “lesbian/bisexual femme,” and “straight femme.” The effects of participants’ sexual and gendered statuses on their retrospective accounts of two aspects of tomboyism—“choosing masculinity” and “rejecting femininity”—were examined. Chi square and qualitative analyses suggest that stage in the life cycle, gender, and sexual status influence distinct mergings and separations of sex, gender, and sexuality in women’s retrospective reports. The researcher concludes that attention to sex, gender, and sexuality as both distinct and connected clarifies the relationship between tomboyism and lesbianism.Part of this paper was presented at the Annual Meeting of the American Sociological Association in Atlanta, Georgia in 2003. Interview data for this study were originally collected for an unpublished dissertation (Carr, 2002).

Romantic competence behavior during problem solving among emerging adult dating couples: Development of an observational coding system

This study examined the hypothesis that romantic competence (RC) skills would be demonstrated behaviorally during dating couple problem solving interactions. A coding system was developed for RC behavior, and its validity was examined through its association with relationship satisfaction and negative affect expressed. A total of 106 emerging adult dating couples in different‐sex relationships were assessed using the Romantic Competence Interview for Emerging Adults, and they participated in a dyadic problem‐solving interaction coded for RC behavior and negative affect. Men's behavioral RC was positively associated with both his and his partner's satisfaction. Behavioral RC was also more associated with satisfaction than was negative affect. Implications for the utility of teaching RC skills in young couples are discussed.
