Proportional reasoning involves thinking about parts and wholes (i.e., about fractional quantities). Yet, research on proportional reasoning and fraction learning has proceeded separately. This study assessed proportional reasoning and formal fraction knowledge in 8- to 10-year-olds. Participants (N = 52) saw combinations of cherry juice and water in displays that highlighted either part–whole or part–part relations. Their task was to indicate on a continuous rating scale how much each mixture would taste of cherries. Ratings suggested the use of a proportional integration rule for both kinds of displays, although more robustly and accurately for part–whole displays. The findings indicate that children may be more likely to scale proportional components when being presented with part–whole as compared with part–part displays. Crucially, ratings for part–whole problems correlated with fraction knowledge, even after controlling for age, suggesting that a sense of spatial proportions is associated with an understanding of fractional quantities. 相似文献

SEXIST DISCRIMINATION MAY ACCOUNT FOR WELL-KNOWN GENDER DIFFERENCES IN PSYCHIATRIC SYMPTOMS 总被引:3,自引:1,他引:2
It was hypothesized that women may have more depressive, anxious, and somatic symptoms than men because they experience a deleterious stressor that men do not: sexist treatment. A total of 255 students (180 females, 75 males) at a state university completed an anonymous questionnaire containing measures of these symptoms. Women were found to exhibit significantly greater symptoms than men on all of them. Further, women who experienced frequent sexism had significantly more symptoms than men on all symptom measures, whereas women who experienced little sexism did not differ from men on any symptom measure. These findings suggest that gender-specific stressors not only play a role in psychiatric symptoms among women but may account for well-known gender differences in those symptoms as well. 相似文献

The present study assessed the effects of drinking and behavioral ambiguity on perceptions of sexual aggression. Male participants, randomly assigned to 1 of 4 alcohol conditions (low, moderate, placebo, or control) viewed a videotaped interaction involving a couple meeting before a blind date. In the receptive condition, the female was friendly and excited. In the nonreceptive condition, she showed rigid posture and lacked enthusiasm. Participants then judged the acceptability of sexual aggression against the female and the attribution of the female's responsibility. Findings indicated a significant interaction such that in the receptive condition, higher alcohol doses elicited both greater acceptance of sexual aggression and greater attribution of female responsibility. There was no impact of alcohol dosage in the nonreceptive condition. 相似文献

The relationship between the openness to experience trait (OTE) and creativity has been well documented in previous research. Likewise, the global citizenship construct has theoretical overlap with both OTE and creativity. We hypothesised global citizenship would make a unique contribution to explaining variance in five types of creativity (self/everyday, scholarly, performance, mechanical/scientific and artistic), above and beyond the contribution of OTE. Participants were predominantly female, European American, traditionally aged college students (N = 407). Global citizenship prosocial outcomes explained unique variance in self/everyday (sr2 = .10), scholarly (sr2 = .03) and mechanical/scientific (sr2 = .03) creativity. Results are discussed in terms of dual processes theories of cognition. 相似文献

We explore how the choices available to individuals planning multi‐task work can facilitate the incubation of ideas and enhance creative performance. Using opportunistic assimilation theory, we hypothesize that two considerations can determine the effectiveness of incubation and creative performance. First, we argue that having the discretion to switch tasks when needed, as well as the timing of this discretionary switch between tasks (i.e., earlier versus later in the work process on the main task) is important. Second, the scope of the intervening task (i.e., in the same knowledge domain as the main task versus in a different domain) can lead to more effective incubation and creativity. Results of a laboratory study indicate that participants who made a discretionary switch to an intervening task later in their work process on the main task benefited significantly more in terms of creative performance than those who chose to switch earlier in their work process or chose not to switch tasks. Additionally, participants who worked on an in‐domain intervening task exhibited significantly higher creativity on the main task than those who worked on an out‐of‐domain intervening task. Furthermore, focus of attention on the main task partially mediated these results. 相似文献

African American adolescent girls are at increased risk of being exposed to community violence and being diagnosed with a sexually transmitted infection. Fewer studies, however, have examined the protective roles of natural mentorship and organizational religious involvement as potential moderators that could lessen the effects of violence exposure on health risk behavior. Data from 273 African American ninth grade girls were used to test hypothesized independent and moderated‐moderation models. Results suggest that natural mentorship and religious involvement were protective for girls who reported at least one mentor and moderate to high levels of religious involvement. Our findings may be relevant for community stakeholders and organizations that directly interact with religious institutions and community programs that focus on outreach to African American adolescent girls. 相似文献

Background and Objectives: Involvement in wartime combat often conveys a number of deleterious outcomes, including posttraumatic stress disorder (PTSD), depression, hostility, aggression, and suicidal ideation. Less studied is the effect of engagement in wartime atrocities, including witnessing and perpetrating abusive violence.Design and Methods: This study employed path analysis to examine the direct effects of involvement in wartime atrocities on hostility, aggression, depression, and suicidal ideation independent of combat exposure, as well as the indirect effects via guilt and PTSD symptom severity among 603 help-seeking male Vietnam War veterans.Results: Involvement in wartime atrocities was predictive of increased guilt, PTSD severity, hostility, aggression, depressive symptoms, and suicidal ideation after controlling for overall combat exposure. Combat-related guilt played a minor role in mediating the effect of atrocity involvement on depression and suicidal ideation. PTSD severity had a larger mediational effect. However, it still accounted for less than half of the total effect of involvement in wartime atrocities on hostility, aggression, and suicidal ideation.Conclusions: These findings highlight the heightened risk conveyed by involvement in wartime atrocities and suggest that the psychological sequelae experienced following atrocity involvement may extend well beyond guilt and PTSD. 相似文献
