The theory has been misconstrued in four primary ways, which are often expressed as the claims of psychological reductionism, conceptual redundancy, biological reductionism, and hierarchy justification. This paper addresses these claims and suggests how social dominance theory builds on and moves beyond social identity theory and system justification theory. 相似文献

Structural Validation of the Hamilton Depression Rating Scale 总被引:1,自引:0,他引:1

Despite the prolific use of the Hamilton Depression Rating Scale (HDRS), there have been no prior studies using confirmatory factor analysis (CFA) to compare competing HDRS latent structures. The current study undertakes this task, examining CFAs on 397 older adults on the most stable latent models previously posited and a new rationally derived model by Cole and Motivala. CFAs were evaluated in their original first-order structure and in hierarchically related counterparts. All hierarchical models performed significantly better than their first-order counterparts. Moreover, the hierarchical Cole and Motivala model was significantly better on all comparative criteria than any of the other models. However, none of the tested models obtained sufficient fit with the data suggesting psychometric, scoring, or content limitations of the scale. 相似文献

We develop a general method for applying functional models to natural systems and cite recent progress in protein modeling
that demonstrates the power of this approach. Functional modeling constrains the range of acceptable structural models of
a system, reduces the difficulty of finding them, and improves their fidelity. However, functional models are distinctly different
from the structural models that are more commonly applied in science. In particular, structural and functional models ask
different questions and provide different kinds of answers. As we clarify these differences and articulate how to use these
models jointly, we extend our ability to do science and gain insight into the proper use of the terms organization, order, and emergence when describing systems in nature. 相似文献

- Using a sample of 43 7–8‐year olds and their parents, we examined the extent to which children's judgments about food products are influenced by the same factors as their parents'. The factors manipulated were healthiness of product, brand name familiarity, and use of licensed cartoon characters (children) or celebrity endorsers (parents). Brand name familiarity was a more important factor than familiar cartoon characters or celebrity endorsers on food product evaluations. Parents and girls but not boys rated healthy products higher than unhealthy ones (e.g., breakfast cereal vs. pastries). However, parents placed greater weight on healthiness when choosing products for themselves than when choosing for their children. Discussion focuses on the promotion of healthy eating habits in children.

Tinnitus distress can be reduced by means of cognitive-behavior therapy (CBT), and the treatment can be delivered in different ways. The most recent format is Internet-based self-help. The aim of this study was to compare this treatment (n = 26) with standard group-based CBT (n = 25) in a randomized controlled trial. Outcomes on self-report inventories measuring tinnitus distress were evaluated immediately after and 1 year after treatment. Results showed that both groups had improved, and there were few differences between them. The effect size for the Internet treatment was d = 0.73 (95% CI = 0.16–1.30) and for the group treatment was d = 0.64 (95% CI = 0.07–1.21). The Internet treatment consumed less therapist time and was 1.7 times as cost-effective as the group treatment. At pretreatment patients rated the Internet treatment as less credible than the group treatment. In conclusion, Internet treatment for tinnitus distress merits further investigation, as the outcomes achieved are promising. 相似文献

Using a 5‐year longitudinal study, we investigated the long‐term effects of courses with ethnic studies content and courses with Latino or Black professors on university students' intergroup attitudes. We found that these curricular variables significantly affected the intergroup attitudes of students beyond pre‐existing differences in attitudes and beyond other curriculum variables. As expected, we found differences between ethnic groups: White students showed movement toward other groups as a result of these curricular factors, whereas Latino and African American students showed both increased tolerance toward other groups and movement toward the in‐group. The results are discussed in terms of group status differences between the dominant White majority and the stigmatized Latino and Black minority groups. 相似文献

People may exhibit two kinds of modifications when demonstrating action for others: modifications to facilitate bottom-up, or sensory-based processing; and modifications to facilitate top-down, or knowledge-based processing. The current study examined actors' production of such modifications in action demonstrations for audiences that differed in their capacity for intentional reasoning. Actors' demonstrations of complex actions for a non-anthropomorphic computer system and for people (adult and toddler) were compared. Evidence was found for greater highlighting of top-down modifications in the demonstrations for the human audiences versus the computer audience. Conversely, participants highlighted simple perceptual modifications for the computer audience, producing more punctuated and wider ranging motions. This study suggests that people consider differences in their audiences when demonstrating action. 相似文献

In a 2004 article, we argued that bioethics commissions should be assessed in terms of their usefulness as public forums. A 2006 article by Summer Johnson argued that our perspective was not supported by the existing literature on presidential commissions, which had not previously identified commissions as public forums and that we did not properly account for the political functions of commissions as instruments of presidential power. Johnson also argued that there was nothing sufficiently unique about bioethics commissions to make the public forum perspective particularly applicable. We respond by arguing that analysis of commissions' work as public forums fits well within the literature on commissions, especially on their agenda-setting functions, and that the political functions of commissions are often compatible with their functioning as public forums. We also demonstrate how the origins and concerns of bioethics make public forum analysis particularly applicable to bioethics commissions. 相似文献

The authors addressed the interactions between control of bimanual multijoint coordination tasks and posture. Participants (N = 6) performed 8 coordination patterns that differed in degree of complexity by using their bilateral elbows and wrists under 3 scaled motion speeds while standing on 2 force plates. Results indicated that producing complex bimanual multijoint coordinative tasks affected postural sway, thus resulting in an increase of sway activity. Behavioral as well as mechanical factors accounted for the increased disturbance in postural sway. Those findings suggest that performing complex coordination tasks disrupts postural control in normal young adults. 相似文献
