Aging, Memory, and Comprehension

There are changes in the ability to comprehend and remember information with aging. In general, older adults perform more poorly than younger adults at tasks that require knowledge of the information that was actually encountered. However, they can perform as well as or better than younger adults at tasks involving more global levels of understanding, such as in the use ofinformation in a situation model. This increased emphasis on situation models may serve to compensate for deficits at lower levels of processing and may be achieved through more focused selection of situation-defining information, increased dependence on schemas, and a broader generation and use of inferences.     

On Canonicity and Strong Completeness Conditions in Intermediate Propositional Logics

By using algebraic-categorical tools, we establish four criteria in order to disprove canonicity, strong completeness, w-canonicity and strong w-completeness, respectively, of an intermediate propositional logic. We then apply the second criterion in order to get the following result: all the logics defined by extra-intuitionistic one-variable schemata, except four of them, are not strongly complete. We also apply the fourth criterion in order to prove that the Gabbay-de Jongh logic D₁ is not strongly w-complete. This revised version was published online in June 2006 with corrections to the Cover Date.     

System and flexibility in law

Usually, rhetoric is supposed to provide a model of law which describes legal interactions as volitive, arbitrary, and void of any system. However, the Mainz School, founded by Theodor Viehweg, proves the contrary: without referring to any metaphysics, such as consensus or auditoire universel, it seeks to discover the systematic character and the more or less flexible structures of legal rhetoric.     

驾驶员视觉注意对危险识别的影响及作用机制

驾驶中, 有效的视觉注意模式是驾驶员搜索与识别潜在道路危险的先决条件。通过分析驾驶员视觉注意对危险识别的影响, 提出情境意识假设与心理负荷假设。情境意识假设认为, 情境意识的质量决定了驾驶员视觉注意模式的灵活性, 进而影响危险识别。心理负荷假设认为, 心理负荷水平提高, 驾驶员视觉注意趋于集中, 不利于危险识别。建议未来研究可以在比较不同驾驶员情境意识的认知兼容性, 应用汽车驾驶自动化技术降低心理负荷以及检测并区分情境意识与心理负荷的影响等方面加以深入。     

飞行员情境认知的模糊综合评判

借用环境科学中环境质量评价的概念和方法,建立了飞行员情境认知的多级模糊综合评判模型,并用该模型对飞行员的情境认知进行了综合评判。研究表明,用模糊综合评判方法评价飞行员的情境认知可以提供真实、全面的飞行认知信息,为飞行员的训练有效性及安全性提供可靠依据。     

普通高等医学院校人文医学教育的现状与思考

人文医学教育是高等医学教育的重要组成部分,也是医学发展、医学人才培养的内在要求。普通高等医学院校在这项工作中存在着不足,如课程体系不完善、课程结构不合理、人文气氛短缺等。因此,有必要采取一些措施予以完善,从而跟上国家高等医学教育改革的步伐,促进医学教育的进一步完善。     

儿童欺骗的情境依赖

采用竞争游戏的方式研究3～6岁儿童在外显和隐蔽情境里的欺骗。结果表明4、5岁儿童行为上的隐蔽欺骗和错误信念理解显著相关;3岁儿童语言上的外显欺骗（说谎）和错误信念理解显著相关;各年龄段儿童行为上的外显欺骗和错误信念理解没有显著相关。和Cartson（1998）的研究结果不一致的是,本研究中4、5、6岁儿童的隐蔽欺骗人数显著超过外显欺骗人数。结果提示,语言上的外显欺骗（说谎）不仅和儿童的执行功能有关,还可能和欺骗时的情境压力有关。     

Situation selection across adulthood: the role of arousal

In this study, we investigated age differences in situation selection to understand the role stimulus arousal plays in motivating age differences in this type of emotion regulation. Participants freely selected from a set of affective videos using information about the valence and arousal of each stimulus. There were age differences both in the valence and arousal of selected stimuli. Older adults selected more neutral and low-arousal stimuli while younger adults selected more negative and high-arousal stimuli. We consider these results in light of recent theoretical models and conclude that studies of age differences in emotion regulation must consider both valence and arousal.     

任务规律性对前瞻记忆的影响

采用混合实验设计,结合行为和眼动数据,探讨任务规律性对前瞻记忆的影响。行为结果显示规律已知条件下前瞻记忆成绩显著高于规律未知和无规律条件,规律未知条件下的前瞻记忆成绩在靶线索之后刺激上有高于无规律条件的趋势;眼动结果显示规律已知条件下的注视点最多,首次注视时间最长。结果说明:(1)任务规律性对前瞻记忆成绩具有促进作用;(2)任务规律性促进了对前瞻记忆任务的自动化加工;(3)在规律已知条件下前瞻记忆的加工过程呈现出动态交替的特点。     

不同心理一致感个体压力情境下的情绪特点研究

以46名大学生为被试,利用“九洞仪”创设实验室压力情境,考察不同心理一致感个体压力情境下的情绪反应及恢复特点。结果表明：（1）压力情境下,高、低心理一致感个体的情绪反应存在显著性差异。高心理一致感个体出现较多的积极情绪,低心理一致感个体则以消极情绪体验为主。（2）低心理一致感压力情境诱发出的消极情绪显著多于积极情绪,消极情绪的诱发量较大。（3）压力任务后,高心理一致感个体在情绪恢复量上显著多于低心理一致感个体,心理健康的自我康复力较大。（4）压力任务前后,低心理一致感个体的消极情绪诱发量显著高于恢复量,在消极情绪变化上表现出“诱发多,恢复少”的特点。
