Little is known about the acoustic cues infants might use to selectively attend to one talker in the presence of background noise. This study examined the role of talker familiarity as a possible cue. Infants either heard their own mothers (maternal-voice condition) or a different infant's mother (novel-voice condition) repeating isolated words while a female distracter voice spoke fluently in the background. Subsequently, infants heard passages produced by the target voice containing either the familiarized, target words or novel words. Infants in the maternal-voice condition listened significantly longer to the passages containing familiar words; infants in the novel-voice condition showed no preference. These results suggest that infants are able to separate the simultaneous speech of two women when one of the voices is highly familiar to them. However, infants seem to find separating the simultaneous speech of two unfamiliar women extremely difficult. 相似文献

In this article the standard philosophical method involving intuition‐driven conceptual analysis is challenged in a new way. This orthodox approach to philosophy takes analysanda to be the specifications of the content of concepts in the form of sets of necessary and sufficient conditions. Here it is argued that there is no adequate account of what necessary and sufficient conditions are. So, the targets of applications of the standard philosophical method so understood are not sufficiently well understood for this method to be dependable. 相似文献

IntroductionThe mortality rate in Portuguese prisons is the highest of the European Community. Two thirds of these deaths concern individuals in preventive detention, who have not yet faced trial.ObjectiveOur objective is to examine the impact of different detention conditions on the anxiety and depression rates of inmates. We predict that the anxiety and depression rates would be higher for inmates in preventive detention.ResultsResults have shown that the depression rates of inmates in open detention were the lowest. Depression rates were highest among inmates in preventive detention.DiscussionThe results do not allow us to confirm our hypothesis regarding anxiety rates. Considering our results, inmates in preventive detention seem to represent the most vulnerable population of the prison in relation to the two other groups. 相似文献

This study maintains that postwar resilience should be defined by the proportion of recovery from war adversity and level of postwar symptoms. We hypothesize first that four resilience-promoting factors will predict this measure of resilience. Second, these associations will be mediated by sense of postwar danger. Third, war-afflicted older people will be comparable to younger people on these variables. The sample included 829 Israeli adults who experienced the 2006 second Lebanon war. Results that have generally supported these hypotheses have been discussed in terms of the definition of resilience, the role of sense of danger in postwar adjustment, and the resilience of older people to war. 相似文献

Does reasoning to a certain conclusion necessarily involve a normative belief in support of that conclusion? In many recent discussions of the nature of reasoning, such a normative belief condition is rejected. One main objection is that it requires too much conceptual sophistication and thereby excludes certain reasoners, such as small children. I argue that this objection is mistaken. Its advocates overestimate what is necessary for grasping the normative concepts required by the condition, while seriously underestimating the importance of such concepts for our most fundamental agential capacities. Underlying the objection is the observation that normative thoughts do not necessarily cross our minds during reasoning. I show that proponents of the normative belief condition can accommodate this observation by taking the required normative belief to guide the reasoning process and offer a novel account of what such guidance consists in. 相似文献

作为多媒体学习中一种重要的指导性教学设计形式, 线索能否引导学习者的注意并促进学习效果, 目前结论尚不一致。研究运用元分析技术, 分别以保持测验、迁移测验的成绩作为学习效果的结果变量, 以线索区的注视时间、注视次数作为注意引导的结果变量, 探讨多媒体环境中的线索对学习效果和注意引导的影响, 并通过调节效应检验考察线索效应的边界条件。采用严格标准进行文献检索和筛选后, 共获取43篇符合元分析的文献。在保持测验成绩和迁移测验成绩上, 分别生成了44个(3910人)和41个(3906人)独立效应量; 在对线索区的注视时间和注视次数上, 分别生成了14个(938人)和11个(816人)独立效应量。结果发现, 线索的加入显著提高了保持测验成绩(g = 0.53)和迁移测验成绩(g = 0.36), 同时也增加了学习者对线索区的注视时间(g = 0.50)和注视次数(g = 0.70)。调节效应分析发现:在保持测验成绩上, 静态学习材料、陈述性知识、理工科条件下的线索效应分别高于动态学习材料、程序性知识和文科; 在迁移测验成绩上, 时空线索、静态学习材料、陈述性知识条件下的线索效应分别高于物理线索、动态学习材料和程序性知识; 而在眼动指标上, 线索对注意的引导主要受线索类型的调节, 物理线索条件下学习者对线索区的注视时间和注视次数均高于时空线索。结论认为, 线索的加入确实促进了学习者对学习材料的识记和理解效果, 同时也引导了学习者的注意分配; 但线索效应一定程度上受线索类型、学习材料动态性、知识类型、学科属性等因素的调节。未来研究需进一步考察线索效应的其他边界条件。 相似文献

医患双方对医患关系认知差异性的调查分析 总被引:20,自引:4,他引:16
采取整群随机抽样方法,现场调查发现,医患双方对医患关系重要性的认知一致,而对其性质、发展趋势、法律适用,以及医患冲突的主要诱因、责任主体、主要解决方式的认知状况均存在着显著性差异。相互理解、交流和尊重是建立和谐医患关系的根本措施。 相似文献
