To test if dreams contain remote or never-experienced motor skills, we collected during 6 weeks dream reports from 15 paraplegics and 15 healthy subjects. In 9/10 subjects with spinal cord injury and in 5/5 with congenital paraplegia, voluntary leg movements were reported during dream, including feelings of walking (46%), running (8.6%), dancing (8%), standing up (6.3%), bicycling (6.3%), and practicing sports (skiing, playing basketball, swimming). Paraplegia patients experienced walking dreams (38.2%) just as often as controls (28.7%). There was no correlation between the frequency of walking dreams and the duration of paraplegia. In contrast, patients were rarely paraplegic in dreams. Subjects who had never walked or stopped walking 4–64 years prior to this study still experience walking in their dreams, suggesting that a cerebral walking program, either genetic or more probably developed via mirror neurons (activated when observing others performing an action) is reactivated during sleep. 相似文献

Work–home interference (WHI) is a prevalent problem because most employees have substantial family responsibilities on top of their work demands. The present study hypothesized that high job demands in combination with low job resources contribute to WHI. The job demands–resources (JD-R) model was used as a theoretical framework. Using a sample of 230 medical residents and their partners, our results show that the combination of high job demands (i.e., work overload, emotional and cognitive demands) and low job resources (i.e., participation in decision making, supervisory coaching, feedback, and opportunities for development) was positively related to partner ratings of the employee's WHI. When job resources were high, most job demands were not related to WHI. These findings show that the JD-R model is a conceptual framework that can be fruitfully applied to the work–family interface, adding to our understanding of which particular job designs facilitate or prevent work–home interference. 相似文献

A Random Digit Dialing survey (n = 794) examined the interracial contact experiences and racial attitudes of White South Africans. The survey measured racial attitudes not only in terms of individuals' prejudice, but also in terms of their perceptions of group threat, perceived injustice, and support for various government policies designed to rectify the legacy of apartheid. The results indicated that the frequency and quality of interracial contact predicted Whites' support for both race compensatory and race preferential policies of redress, and these effects were partly mediated by perceived threat, sense of fairness, and racial prejudice. The research points to a potential rapprochement between the social psychological theories of intergroup contact and group positioning theories derived from the work of Blumer. It also highlights the value of adopting a more expansive and politically nuanced conception of the “consequences” of contact and desegregation. 相似文献

Terror management theory (TMT) proposes that people who are reminded of their mortality should be motivated to defend their cultural worldview. Studies 1 and 2 examined whether the TMT worldview defence‐buffering effect found in Western cultures could be generalized to Asians in Taiwan. No such effect was found in the present studies. This non‐significant result was robust when either a stronger distraction task was used (study 1) or when a subliminal manipulation of mortality salience was utilized (study 2). A meta‐analysis, including 24 TMT experiments in East Asia, was also conducted (study 3). The average effect size (d = 0.11, r = 0.055) of worldview defence among these experiments was not significantly different from zero. Study 4 found that mortality salience manipulation also did not change Taiwanese participants' view of reincarnation; however, it did make them more inclined to resign to fate, suggesting that they might be using this symbolic means to defend their anxiety of death. The issue of the generality of TMT to Asians was discussed. 相似文献

视觉选择的过程包含两种途径:眼跳行动和注意转移,两者对于视觉选择目标物的加工都有促进作用。鉴于此,视觉研究领域产生大量关于二者关联如何的实验研究,大部分研究者认为眼跳和注意转移存在密切联系。该文将关于两者关系的重要理论进行了综合阐述和简要比较,主要介绍五种理论假说:眼动准备假说、动前假说、顺序注意模型、视觉注意模型和竞争整合模型。 相似文献

研究使用图形面积判断任务取代典型的双属性决策框架, 考察了不同信息加工模式和信息呈现方式对吸引效应的影响。实验1比较了不同信息加工模式对吸引效应的影响, 结果发现, 当被试以直觉的信息加工方式进行面积比较判断时, 吸引效应不显著, 而以分析的信息加工方式判断时吸引效应明显存在, 后者效应强度显著大于前者。实验2通过调整图形排列顺序, 比较了刺激材料呈现方式对吸引效应的影响, 结果表明, 被试以直觉的信息加工方式进行判断时吸引效应依然存在, 但其表现要受信息呈现方式影响, 相对于将目标图形放置于诱引图形和竞争图形之间, 将诱引图形放置于目标图形和竞争图形之间而成为判断背景时, 吸引效应强度更大。研究提出了吸引效应形成的两阶段理论, 认为吸引效应产生的根源同时来自直觉的和分析的两个信息加工阶段, 研究也证实信息呈现方式对被试信息加工方式造成较大影响, 进而影响吸引效应强度。 相似文献

采用句-图匹配范式,以可预测对立意义的句子和图片为实验材料,考察汉语双重否定的加工方式以及句子的形式与语义对句子加工的影响,包括2个实验。研究发现:(1)双重否定是整体加工的;(2)在理解初期(250ms),否定反问句、双重否定祈使句与肯定祈使句的加工模式一致,都是直接表征事件的实际状态;(3)当句子形式与语义不一致时,读者更多地受到句子语义的影响。这表明,在双重否定加工机制的理论解释中,命题表征理论忽略语义,注重句子形式结构,而基于经验模拟理论的两步模拟假设则立足语义,忽略句子形式结构,两者都有一定的合理性,但也都存在一定的片面性。 相似文献
