时间顺序与时间距离对语言理解的影响:进一步的证据

探讨时间顺序和时间距离对语言理解的影响,包括2个实验.实验采用关系再认范式(relation-recognition paradigm)和句子-探测再认范式(sentence-probe-recognition paradigm).实验一探讨探讨在简单句条件下,时间顺序对不同频率事件理解的作用;实验二探讨在复句条件下时间顺序与时间距离对语言理解的影响.2个实验结果一致表明,在语言理解过程中,存在对将来取向(顺时序)的事件进行优先加工处理.时间距离对语言理解的影响取决于不同时距的事件能否整合成情景模型.     

Perceived relative distance on the ground affected by the selection of depth information

Our visual space does not appear to change when we scan or shift attention between locations. This appearance of stability implies that the depth information selection process is not crucial for constructing visual space. But we present evidence to the contrary. We focused on space perception in the intermediate distance, which depends on the integration of depth information on the ground. We propose a selection hypothesis that states that the integration process is influenced by where the depth information is selected. Specifically, the integration process inaccurately represents the ground when one samples depth information only from the far ground surface, instead of sequentially from the near to the far ground. To test this, observers matched the depth/length of a sagittal bar (test) to the width of a laterally oriented bar (reference) in three conditions in a full-cue environment that compelled the visual system to sample from different parts of the ground. These conditions had the lateral reference bar placed (1) adjacent to the test bar, (2) at the far ground, and (3) at the near ground. We found that the sagittal bar was perceived as shorter in conditions (1) and (2) than in Condition 3. This finding supports the selection hypothesis, since only Condition 3 led to more accurate ground surface integration/representation and less error in relative distance/depth perception. Also, we found that performances in all three conditions were similar in the dark, which has no depth information on the ground, indicating that the results cannot be attributed to asymmetric visual scanning but, rather, to differential information selection.     

自我控制行为中的情绪因素

对冲动行为的控制及失控(放任)会产生不同的情绪结果,并形成两种自我控制的两难:失控后可能产生的愉悦与内疚、成功自控后可能产生的自豪与遗憾。自控行为-情绪结果的联结,使个体能自发地基于预期情绪选择当前行为。情绪预测会受到情境、个体差异等的影响,并有一定的误差。     

海员安全意识初步研究

本研究采用自编的海员安全意识量表(SSCS)对367名海员的安全意识进行了问卷调查,结果显示：(1)绝大多数海员的安全意识较强;(2)不同年龄、工龄、海龄组海员的安全意识无显著差异;(3)甲板部海员的法制观念显著低于轮机部海员;(4)高级海员的责任感和合作性显著低于普通海员;(5)不同文化程度、来源与婚姻状况海员的安全意识没有显著差异。     

组织变革的多样性管理:一种系统性框架

组织的变革是组织发展的一个关键。但是研究表明,对于组织变革的管理相对比较薄弱．而在方法论上的一些探索有助于解决组织变革管理薄弱的问题。本文将简要阐述在组织变革管理中所应用的一些方法及其不足,并就系统观以及与组织变革管理相关的问题作一些讨论。在组织变革过程中系统性框架的应用将有助于解决组织多纬度变革的差异及其多纬度变革间的相互作用问题。因此．系统性框架对于理解和管理组织的变革是非常有作用的。     

文章标记效应的初步实验研究

探讨文章阅读过程中文章宏观标记与微观标记对文章不同类型信息保持的影响．包括两个实验。结果表明,文章宏观标记对文章主题信息的保持有显著的促进效应,而且,这种促进效应可以扩散到从属信息的保持上;文章微观标记对文章主题信息的保持无明显的促进效应,对被标记的文章具体信息的保持则有显著的促进效应。但不存在扩散效应。本研究结果初步表明,读者利用文章宏观标记建构文章主题的表征,并且以一种自上而下的方式指导文章信息的回忆;通过利用文章微观标记建构文章具体信息的表征,指导具体信息的回忆。     

人类基因组计划与博士生的时代意识

人类基因组计划（HGP）的成就表明,面对新世纪的挑战,作为肩负国家重任的高层次人才的博士生更要转变观念,增强时代意识,发展（科技）战略意识、科技前沿意识,创新意识,市场意识,协作意识。其中尤以发展（科技）战略意识最为重要,其影响深远,意义重大。     

三一教仪式研究

仪式对于宗教来说具有非常重要的意义,正是通过各种特殊的仪式,宗教形式本身的独特性才得以直观地表现出来,宗教组织才在形式上被有效地凸现出来,宗教所具有的社会功能和道德教化的价值才得以实现.因此,对于一种宗教形式的讨论,不能脱离对其独特的仪式的考察.作为一种民间宗教形式,三一教同样有其完整的宗教仪式.本文通过田野调研,对三一教的仪式(入教、会道、诞庆)作了详细的分析,并进而探讨其特征和意义.     

情绪加工老化效应的神经机制

行为学研究发现,老年人对消极情绪的辨别、注意和记忆都有所下降,而对积极情绪并未表现出类似的现象。情绪加工老化效应的神经影像学研究发现,老年人在情绪加工过程中边缘系统（尤其杏仁核）的激活强度低于年轻人,但额叶皮层区域的激活却有所增强。研究者对该结果提出了两种假说,一种是功能代偿假说,另一种是策略改变假说。功能代偿假说认为老年人额叶皮层区域的激活增强是为了弥补边缘系统功能的下降,反映了大脑功能的代偿;策略改变假说认为老年人主动使用了不同于年轻人的策略,情绪加工方式的不同导致了两组人群大脑活动的差异。未来这方面研究可以从研究层面、研究方法、研究问题等方面逐步完善     

Chinese character recognition in mirror reading: evidence from event-related potential

As is well known, mirror reading in language requires recognition of words and letters in mirror-reversed pattern compared with normal reading, and the cognitive mechanism underlying the mirror reading may involve two critical processes: visuospatial transformation and linguistic regulation. Chinese characters, different from English, are characterized by some unique features in orthography and spelling. Using ERP techniques, the present study investigated neural correlates underlying the mirror reading of Chinese characters, and whether the cognitive processes underlying the recognition of mirrored Chinese characters is different from those of alphabetic words. Twelve native Chinese speakers participated in the experiment, during which they were instructed to make an animal/nonanimal distinction. The stimuli varied with the word category (animal vs nonanimal) and presentation format (normal vs mirror-reversed). The data analyses focused on three aspects: the reaction times (RT) for Chinese words of normal and mirror-reversed formats, peak latencies, and peak amplitudes of ERP components elicited by mirror-reversed and normal Chinese words. The results from implicit reading provide evidence for a mirror-reversed effect. The behavioural data showed that mirror-reversed words were more difficult to identify than normal words, with RTs delayed for mirror-reversed words over normal words. Moreover, a clear N2 component, with maximal activity occurring at 200-250ms interval (N2), was more negative for mirror-reversed words than for normal words at posterior regions. However, there were no latency differences between normal and mirror-reversed words. The occipital N2 might be closely related to abstract word form representation. Larger N2 amplitude in response to mirror-reversed Chinese words is interpreted as reflecting visuospatial transformation in order to compensate for impaired word form analysis. The result of no N2 latency delay indicated that word form analysis and visuospatial transformation might be processed in parallel.
