Little research has investigated males?? reactions to non-objectified media images of women, including those that depict women in instrumental activities like playing a sport. Using a survey methodology, this study examined U.S. adolescent boys?? open-ended responses to images of performance athletes, sexualized athletes, and sexualized models. Participants were 104 adolescent boys from California (ages 12?C17, primarily European-American). They remarked on the performance athletes?? physical competence and focused on the athletic context depicted in the photograph. In contrast, participants focused on the physical appearance and attractiveness of the sexualized athletes and sexualized models. Overall, findings suggest that performance images of women evoke instrumental evaluations of women from male viewers, while sexualized images induce objectified appraisals.  相似文献

This study tests the ability of classroom emotional climate to moderate anxious solitary children's risk for peer exclusion over a 3-year period from 3rd through 5th grade. Six hundred eighty-eight children completed peer nominations for anxious solitude and peer exclusion in the fall and spring semesters of each grade, and observations of classroom emotional climate were conducted at the same time points. Results revealed a positive relation between anxious solitude and peer exclusion in the fall semester of each grade. However, in classrooms with supportive versus unsupportive emotional climates, this relation demonstrated a different pattern of change from fall to spring semesters. In classrooms with supportive emotional climates, children with high versus low levels of anxious solitude experienced relative elevation in fall peer exclusion, but this disappeared by the spring, such that spring peer exclusion levels were equalized among children who differed in anxious solitude. This result is consistent with hypotheses guided by the Child × Environment model. However, in classrooms with unsupportive emotional climates, results did not conform to expectations that children with high anxious solitude would experience stable or increased peer exclusion over time.  相似文献

In this paper we examine how English and Mandarin speakers think about time, and we test how the patterns of thinking in the two groups relate to patterns in linguistic and cultural experience. In Mandarin, vertical spatial metaphors are used more frequently to talk about time than they are in English; English relies primarily on horizontal terms. We present results from two tasks comparing English and Mandarin speakers' temporal reasoning. The tasks measure how people spatialize time in three-dimensional space, including the sagittal (front/back), transverse (left/right), and vertical (up/down) axes. Results of Experiment 1 show that people automatically create spatial representations in the course of temporal reasoning, and these implicit spatializations differ in accordance with patterns in language, even in a non-linguistic task. Both groups showed evidence of a left-to-right representation of time, in accordance with writing direction, but only Mandarin speakers showed a vertical top-to-bottom pattern for time (congruent with vertical spatiotemporal metaphors in Mandarin). Results of Experiment 2 confirm and extend these findings, showing that bilinguals' representations of time depend on both long-term and proximal aspects of language experience. Participants who were more proficient in Mandarin were more likely to arrange time vertically (an effect of previous language experience). Further, bilinguals were more likely to arrange time vertically when they were tested in Mandarin than when they were tested in English (an effect of immediate linguistic context).  相似文献

Epidemiologically, disasters represent multiple forms of possible exposures, including exposure type (eg, natural versus human-made), intensity, and duration. It has been suggested that the consequences of human-made disasters (eg, terrorist incidents) may be more severe than those of natural disasters; recent evidence suggests that there may be a high prevalence of posttraumatic stress disorder (PTSD) among both direct survivors of such attacks and in the general population. Several studies after the September 11, 2001, terrorist attacks found that the prevalence of PTSD was higher in New York City than it was in the rest of the US and that there was a substantial burden of PTSD among persons who were not directly affected by the attacks. This raises important questions about the meaning of "exposure" to a disaster. Using data from an assessment of PTSD in the first 6 months after September 11th we considered the nature of the PTSD experienced by persons who were not directly affected by the September 11th attacks. These data suggest that persons in the general population may have clinically important posttraumatic stress symptomatology after a mass terrorist incident. Future research should consider mechanisms through which persons in the general population may be at risk for PTSD after such incidents.  相似文献

The present study investigated whether the relationship between mathematics participation and mathematics achievement is reciprocal for boys and girls. In Years 1, 2, 4 and 6 (US grades 7, 8, 10 and 12), we administered mathematics achievement tests to a cohort of 1,495 Flemish students and collected data on the number of classroom hours allocated to mathematics. A cross-lagged panel design was used to analyze the data. Evidence was found for a reciprocal relationship between mathematics participation and mathematics achievement, particularly in Years 4 and 6 (US grades 10 and 12). The results suggest that boys’ better performance in mathematics is related to their higher participation in math, whereas other factors—in addition to gender differences in math achievement—play a role in explaining why boys participate more in mathematics than girls.  相似文献

Pairs of laboratory rats were rewarded with sugar solution for cooperating by means of synchronized shuttling in a rectangular chamber. Learning and performance were compared in males and females of three strains--S3, Charles River, and Wistar--ordered in terms of decreasing levels of aggressiveness. In addition, same-sex pairs of each strain were housed either together or individually. When housed together, males and females of all strains eventually cooperated at comparable levels, with rates of acquisition across strains inversely related to their aggressiveness. Individual housing, in contrast, was associated with severe deficits in males of the S3 and CR strains linked to violent fighting and prolonged freezing by animals who had previously been defeated. All other individually housed groups, including males of the Wistar strain and females of all strains, were able to cooperate, including S3 females whose violent fighting was not associated with immobility by defeated animals. In general, the majority of groups were able to cooperate despite differences in aggressiveness associated with sex, strain, and housing. Possible processes in this accommodation are discussed.  相似文献

During the COVID-19 pandemic, pregnant women, especially those from socioeconomically disadvantaged and marginalized groups, experienced unprecedented stress. Prenatal stress and social determinants of health (SDoH) such as lower education and lack of a relationship partner are known to contribute to earlier birth. However, whether SDoH and stress independently contribute or whether the harmful impact of SDoH is mediated by stress is unknown. Moreover, the contributions of these factors has not been investigated in the context of a communal health crisis such as the COVID-19 pandemic. To examine these processes, we used a longitudinal cohort of 2473 women pregnant during the COVID-19 pandemic who reported a live birth. We compared structural equation models predicting gestational age at birth from SDoH (race/ethnicity, education, financial security, health insurance, relationship status, and lifetime abuse) and from prenatal maternal stress related and unrelated to the COVID-19 pandemic. Results indicate that the association of SDoH with earlier birth was partially mediated by prenatal stress. These findings help uncover mechanisms explaining health disparities in the U.S. and highlight the need to address both SDoH and the stress that these factors produce in under-resourced and marginalized communities.  相似文献

Modern technologies can aid working processes as well as provide individuals with an opportunity to connect and form interpersonal relationships. However, they can also create a context for displaced aggression. In this study, we examine whether people experiencing work stressors may engage in online antisocial behavioral as a means of venting their negative emotions. Specifically, we investigate whether experiencing stressors at work fuels anger in the private context and whether this anger triggers subsequent displaced aggression in the form of antisocial online behavior (AOB) throughout the evening. Additionally, we examine the crossover of anger to AOB in couples in their private context. We conducted a diary study amongst 95 dual-earner couples, twice a day, during five consecutive working days. Results confirmed that men’s daily work stressors spilled over to their private context in the form of anger after work and AOB throughout the evening. No crossover effects were found from their partner. For women, a crossover effect was found of their partner’s work stressors and anger on their own AOB. These results demonstrate gender differences in displaced online aggression.  相似文献

We examined the relationship between meditation experience, psychological mindfulness, quiet ego characteristics, and self-reported physical health in a diverse sample of adults with a range of Buddhist experience (N = 117) gathered from a web-based survey administered to Buddhist practitioners around the world between August 1, 2007 and January 31, 2008. Practicing meditation on a regular basis and greater experience with Buddhism was related to higher psychological mindfulness scores. Psychological mindfulness was correlated with a latent variable called “quiet ego characteristics” that reflected measures based on Bauer and Wayment’s (Transcending self-interest: psychological explorations of the quiet ego. American Psychological Association, Washington, DC, pp 7–19, 2008) conceptual and multidimensional definition of a “quiet ego”: wisdom, altruism, sense of interdependence with all living things, need for structure (reversed), anger/verbal aggression (reversed), and negative affectivity (reversed). In turn, quiet ego characteristics were positively related to self-reported health. Our findings provide continuing support for the key role psychological mindfulness may play in psychological and physical well-being.  相似文献
