This study investigated memory from interrupted visual searches. Participants conducted a change detection search task on polygons overlaid on scenes. Search was interrupted by various disruptions, including unfilled delay, passive viewing of other scenes, and additional search on new displays. Results showed that performance was unaffected by short intervals of unfilled delay or passive viewing, but it was impaired by additional search tasks. Across delays, memory for the spatial layout of the polygons was retained for future use, but memory for polygon shapes, background scene, and absolute polygon locations was not. The authors suggest that spatial memory aids interrupted visual searches, but the use of this memory is easily disrupted by additional searches.  相似文献

How have Jews in Germany, stranded or returned there after World War II, related to Israel and to Germany, and how have their attitudes evolved since then? For decades, most Jews had no plans to stay in Germany, and their identification with and commitment to Israel, certainly in the first two decades, was extraordinary. However, over time their distance and even hostility to the German environment began to lessen, especially as West Germany developed ever closer ties with Israel. To a considerable degree, Germans themselves first reinitiated contacts with Jews and Jewish issues via Israel. In recent years, coinciding with the influx of Russian Jews and the policies of the Netanyahu and Sharon governments, there has been renewed emphasis on Diaspora and its values and a more positive reappraisal of the history of Jews in Germany. Nonetheless, basic ambivalences remain in place.  相似文献

科学不确定性的类型、来源及影响   总被引:8,自引:0,他引:8  
徐凌 《哲学动态》2006,1(3):48-53
随着科学认识对象的日益复杂,以及科技和社会的相互影响日益加强,科学认识能力的历史局限性凸显了出来,使得在知识的生产、应用,以及利用知识进行决策的过程中,显示了种种不确知或不知道(not-knowing),这就是科学技术的不确定性。沃克(W.E.W allker)认为,不确定性是“任何对难以达到的完全决定论的偏离”[1]。范·阿塞尔特(M.B.A.Van Asselt)认为,不确定性是“整套的信念或者疑惑,它们来自对过去和现在状况的有限的知识,以及预测未来事件”[2]。不确定性在现代科技中普遍存在,并意味着风险,以至于吉登斯(Anthony G iddens)和贝克(Ulric…  相似文献

This research is designed to assess the links between interpersonal behaviors and relationship development. A measure of friendship, labeled 'communion', was developed that focused exclusively on the characteristics of the relationship itself. It was hypothesized that greater use by both parties of behaviors promoting the interests of the other, 'beneficence', and of behaviors respecting the rights of the other, 'restraint', would result in greater communion between the roommates by the end of their first 6 months together. Both dimensions of behavior proved to be related to communion, although beneficence by both parties was relatively stronger than restraint. These findings were discussed in terms of other types of relationships where there is less freedom of involvement and greater hierarchy.  相似文献

巴黎外方传教会档案材料显示,巴黎外方传教会的形成是十七世纪罗马为了落实天主教远东本土化政策和力排葡萄牙远东保教权而采取的一系列努力行动的结果。虽然巴黎外方传教会在传教经费来源上与法国政府具有一定的资助关系,但就其本质而言,它首先是一个在组织上直属于罗马的传教团体(Association),而非宗教修会(Congrégation),其主要目的是协助传信部建立远东土著教会,因此巴黎外方传教会入华对天主教中国本土化过程曾经产生过推动作用。  相似文献

The NEO Five-Factor Inventory is the shortened version of the Revised NEO Personality Inventory. The aim of this study was to examine the reliability and validity of the Japanese version of the shortened version in the general population of Japan. This version was translated into Japanese and then administered to 2,051 adults in a rural town in Akita Prefecture. A total of 1,664 (81.1%) individuals gave valid answers. Internal reliability, assessed by Cronbach alpha for subscales, ranged from .60 to .77. The scales were only weakly correlated both with each other and with age. In a multiple regression analysis, only the Neuroticism scale score was a significant predictor of scores on the General Health Questionnaire. Factor analysis supported the theoretical structure of personality. Overall, the Japanese version showed good reliability and validity in this sample of the general population of Japan.  相似文献
