8—12岁超常与常态儿童的检测时比较

研究者采用两种视觉检测时任务,比较了8至12岁超常和常态儿童的检测时发展变化特点。结果发现：随着年龄的增长,超常组和常态组儿童的检测时都呈现出逐步减小的趋势,并且对于不同任务的检测时,两组儿童的发展速度不同,但均未表现出性别差异;在不同的年龄段和检测时任务中,超常组儿童的检测时均显著地快于常态组儿童。通过对两组儿童的检测时发展速率的比较还发现,儿童的检测时发展基本上不受学校知识或经验的影响。另外,两组儿童的检测时和智力测验分数之间都有中等程度的负相关。     

Metaphorical mapping between raw–cooked food and strangeness–familiarity in Chinese culture

Previous research has demonstrated metaphorical mappings between physical coldness–warmth and social distance–closeness. Since the concepts of interpersonal warmth are frequently expressed in terms of food-related words in Chinese, the present study sought to explore whether the concept of raw–cooked food could be unconsciously and automatically mapped onto strangeness–familiarity. After rating the nutritive value of raw or cooked foods, participants were presented with morphing movies in which their acquaintances gradually transformed into strangers or strangers gradually morphed into acquaintances, and were asked to stop the movies when the combined images became predominantly target faces. The results demonstrated that unconscious and automatic metaphorical mappings between raw–cooked food and strangeness–familiarity exist. This study provides a foundation for testing whether Chinese people can think about interpersonal familiarity using mental representations of raw–cooked food and supports cognitive metaphor theory from a crosslinguistic perspective.     

再探汉字加工中语音、语义激活的相对时间进程

在Zhou和Marslen-Wilson（2000）基础之上,进一步探讨汉字加工中语音和语义信息激活的相对时间进程及其对汉字加工理论的含义。采用启动范式,用同一目标字与语义相关启动字、同音启动字以及无关控制启动字配对,变化同音启动字读音与其声旁的规则性,变化启动字与目标字呈现之间的时间间隔（SOA,57ms或200ms）,使用两种实验任务（真假字判断和命名）,考察语义、语音效应发生的时间先后与效应量的大小。真假字判断实验发现,不管SOA如何,语义启动效应都非常显著,而同音启动效应则随SOA的增长而逐渐加大,从不显著到显著;同音启动字读音规则性对启动效应没有明显影响。命名实验发现,语义启动、同音启动效应同时存在于长、短SOA条件中。长SOA时,两者在数值上没有显著差异;短SOA时,同音不规则字产生的启动效应等同于语义启动效应,而同音规则字产生的启动效应则大于语义启动效应。结合其它实验发现,这些结果说明,在熟练的汉字加工中,语音信息的激活并不比语义信息早,语音激活也不是语义激活的先决条件;但汉字各种信息激活的相对激活量和时间进程会随任务性质和材料性质而在一定范围内有所改变。     

SOA对Stroop启动效应的影响:行为和ERP研究

在Stroop启动范式中,启动刺激是灰色的色词,目标刺激是颜色块,被试的任务是命名颜色块的颜色。本研究通过行为实验和事件相关电位(ERP)实验的方法,研究SOA(Stimulus Onset Asynchrony)对Stroop启动效应的影响。当SOA为107ms时,在行为数据(反应时)和ERP数据(N300成分)上均表现出明显的启动效应;当SOA为1040ms时,行为上和ERP上的启动效应消失。该结果提示了在Stroop启动效应中,启动刺激对目标刺激的影响很可能是发生在对目标刺激的知觉加工晚期。

Specificity of face processing without awareness

The recognition memory for inverted faces is especially difficult when compared with that for non-face stimuli. This face inversion effect has often been used as a marker of face-specific holistic processing. However, whether face processing without awareness is still specific remains unknown. The present study addressed this issue by examining the face inversion effect with the technique of binocular rivalry. Results showed that invisible upright faces could break suppression faster than invisible inverted faces. Nevertheless, no difference was found for invisible upright houses and invisible inverted houses. This suggested that face processing without awareness is still specific. Some face-specific information can be processed by high-level brain areas even when that information is invisible.     

卦象在逻辑推理中的应用研究

<周易>不仅具有哲学的意义,同时也具有科学的价值.这是因为易卦中不仅有传统的易象逻辑形态而且有现代的数理逻辑形态.易卦若是除去神秘的象征意义,其卦象便是精良的推理工具.易卦是一种完备的二值逻辑体系,每一个卦象就是一组真值表.易卦中蕴含大量的逻辑信息,其逻辑价值有待开发.     

"脑死亡=死亡"生物医学定律的逻辑论证

心脏具有顽固自律性、可多次复苏性、功能可人工替代性、可多次置换性四大特点,因而已失去作为死亡判定权威器官的地位.而大脑由于具有统领性、损坏后不可恢复性、功能不可替代性、全脑不可置换性四大特点,已替代心脏成为死亡判定的靶器官."脑死亡=死亡"在相当长时期内都将是一个严格的科学定义.
