Detection of angry and happy faces is generally found to be easier and faster than that of faces expressing emotions other than anger or happiness. This can be explained by the threatening account and the feature account. Few empirical studies have explored the interaction between these two accounts which are seemingly, but not necessarily, mutually exclusive. The present studies hypothesised that prominent facial features are important in facilitating the detection process of both angry and happy expressions; yet the detection of happy faces was more facilitated by the prominent features than angry faces. Results confirmed the hypotheses and indicated that participants reacted faster to the emotional expressions with prominent features (in Study 1) and the detection of happy faces was more facilitated by the prominent feature than angry faces (in Study 2). The findings are compatible with evolutionary speculation which suggests that the angry expression is an alarming signal of potential threats to survival. Compared to the angry faces, the happy faces need more salient physical features to obtain a similar level of processing efficiency.  相似文献

The authors' purpose was to test the effect of asymmetric hand lifting on muscular activation patterns of 3 bilateral extensors. Eighteen male university students without back pain were volunteered. Each performed flexion–extension randomly with conditions of right lifting, left lifting, and nonlifting. Surface electromyography from bilateral thoracic, lumbar erector spinae, and hamstring was recorded. The cross-correlation and relative intensity in paired muscles of bilateral extensors was calculated in flexion as well as extension period. The results showed that the cross-correlation coefficient was decreased and the phase lag as well as the relative intensity of bilateral extensors was increased significantly in thoracic level. The phase lag as well as the relative intensity of bilateral extensors was increased significantly in lumbar level. It was concluded that asymmetric lifting has a significant effect on muscular activation of bilateral extensors in thorax level, which causes the ipsilateral extensor to activate larger and longer. Asymmetric lifting also has some effect on muscular activation of bilateral extensors in lumbar level but with less extent than in thorax level, which causes contralateral extensor to activate larger and longer. Asymmetric lifting seems to have no significant effect on muscular activation of bilateral hamstring.  相似文献

In this study the levels of experienced burnout of Finnish and Chinese university students are compared using School Burnout Inventory (SBI). This study is motivated by earlier studies, which suggest that the level of student burnout is different in the culturally distinct Finnish and Chinese university systems, but which are based on different research instruments for the two groups. The sample studied consisted of 3,035 Finnish students and 2,309 Chinese students. Because of the cross‐cultural nature of this study the level of structural equivalence of SBI between the cultural groups was examined and the effect of different response styles on the results was taken into account. Both standard and robust statistical methods were used for the analyses. The results showed that SBI with two extracted components is suitable for cross‐cultural analysis between Finnish and Chinese university students. Virtually no difference was found in experienced overall burnout between the Finnish and Chinese students, which means that both university systems contain factors causing similar levels of student burnout. This study also verified that controlling for the response styles is important in cross‐cultural studies as it was found to have a distinct effect on the results obtained from mean‐level comparisons.  相似文献

运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。  相似文献

顺从是儿童早期重要的社会化成就。传统理论关注父母控制策略对顺从的作用,但实证结果表明其解释率有限;当前理论更加关注积极养育行为在顺从发展中具有发展适宜性的作用机制。本研究采用追踪设计考察了84个家庭从儿童6个月到3岁时母亲的敏感性和鼓励自主两种积极养育行为与学步儿顺从发展的关系。结果表明:(1)1岁前母亲敏感性对学步儿2岁时的合作性顺从有正向预测作用,对2岁到3岁合作性顺从的变化没有预测作用;(2)1岁前母亲敏感性对学步儿2岁时的情境性顺从和2岁到3岁的情境性顺从的变化均有负向预测作用;(3)在2岁到3岁期间,母亲的鼓励自主与学步儿的合作性顺从水平有双向正向预测作用,但与情境性顺从不存在双向预测关系。  相似文献

We adopt a multilevel approach to investigate ethical ideology, moral leadership, and ethical climate in predicting service-oriented organizational citizenship behavior (OCB) and service sabotage. Data were collected from 36 food and beverage units in hotels in Taiwan. The sample comprised 504 employees and 36 supervisors. Results show that idealism is positively related with service-oriented OCB, but negatively related with service sabotage; relativism is the opposite. Moral leadership and ethical climate are both positively related with service-oriented OCB and negatively related with service sabotage. In addition, moral leadership moderates the relationship between relativism and service-oriented OCB. Ethical climate moderates the relationship between idealism and service-oriented OCB and service sabotage. The implications of this study for research and practice are discussed.  相似文献

本研究探讨了亲社会自主动机对青少年幸福感和亲社会行为的影响,并检验了基本心理需要满足的中介作用。研究1以293名青少年为研究对象,通过问卷法考察了亲社会自主动机、基本心理需要满足、幸福感和亲社会行为的关系;研究2以205名青少年为研究对象,通过实验法操纵亲社会自主动机(vs.受控动机),并考察其对基本心理需要满足、幸福感和亲社会行为的影响。研究结果表明,亲社会自主动机显著正向预测青少年的幸福感和亲社会行为,并且基本心理需要满足在亲社会自主动机对幸福感和亲社会行为的预测中都起到了中介作用;相反,亲社会受控动机则不利于青少年基本心理需要的满足,进而不能有效地提升其幸福感和亲社会行为。  相似文献

基于社会支持理论和社会认知理论,构建以自我效能感为中介变量的理论模型,通过对523名本科生新生问卷调查,检验本科生导师指导影响新生大学适应性的内在机制。回归分析结果显示,导师指导各维度对大学适应性均有显著正向作用;自我效能感在导师指导和大学适应性之间起完全中介作用。这提示高校管理者在具体实施中应该进一步细化和规范新生导师制,并关注学生自我效能感的激发。  相似文献

As genetics and genomics become part of mainstream Medicine, these advances have the potential to reduce or exacerbate health disparities. Gaps in effective communication (where all parties share the same meaning) are widely recognized as a major contributor to health disparities. The purpose of this study was to examine GC-patient communication in real time, to assess its effectiveness from the patient perspective, and then to pilot intervention strategies to improve the communication. We observed 64 English-, 35 Spanish- and 25 Chinese-speaking (n = 124) public hospital patients and 10 GCs in 170 GC appointments, and interviewed 49 patients who were offered testing using the audio recordings to stimulate recall and probe specific aspects of the communication. Data analyses were conducted using grounded theory methods and revealed a fundamental mismatch between the information provided by GCs and the information desired and meaningful to patients. Several components of the communication that contributed to this mismatch and often resulted in ineffective communication included: (1) too much information; (2) complex terminology and conceptually difficult presentation of information; (3) information perceived as not relevant by the patient; (4) unintentional inhibition of patient engagement and question-asking; (5) vague discussions of screening and prevention recommendations. Our findings indicate a need to transform the standard model of genetic counseling communication using evidence-based principles and strategies from other fields of Medicine. The high rates of limited health literacy in the US, increasing access of diverse populations to genetic services, and growing complexity of genetic information have created a perfect storm. If not directly addressed, this convergence is likely to exacerbate health disparities in the genomic age.  相似文献
