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。     

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.     

双任务并存条件下的信息提取

将短时记忆再认与长时记忆范畴判断两类不同性质的信息提取任务相并列,探讨了双任务条件下的信息提取过程是如何进行的。实验结果表明,双任务并存时,ｎｏ反应的总平均反应时不等于两种任务单独进行时各自ｎｏ反应的平均反应时之和（减去一次视觉动作反应时后）,而是与其中一个较后完成的过程的ｎｏ反应平均反应时相近。因此推断双任务并存时,信息提取过程不是完成一个再进行另一个的系列加工过程,而是二者同时平行加工的过程。     

Hume's Internalist Epistemology in EHU 12

Much has been written about Kemp Smith's (1941) famous problem regarding the tension between Hume's naturalism and his scepticism. However, most commentators have focused their attention on the Treatise; those who address the Enquiry often take it to express essentially the same message as the Treatise. When Hume's scepticism in the Enquiry has been investigated in its own right, commentators have tended to focus on Hume's inductive scepticism in Sections 4 and 5. All in all, it seems that Section 12 has been unduly neglected. This paper seeks to address Kemp Smith's problem from the standpoint of Hume's treatment of scepticism in EHU 12, and finds an interesting internalist account that makes sense both of Hume's discussion in EHU 12, and his aims in the Enquiry as a whole. Moreover, it is one that is of substantive philosophical interest, having intriguing parallels to contemporary epistemological accounts.     

The development of morphological representations in young readers: a cross‐modal priming study

The way children organize words in their memory has intrigued many researchers in the past 20 years. Given the large number of morphologically complex words in many languages, the influence of morphemes on this organization is being increasingly examined. The aim of this study was to understand how morphemic information influences English‐speaking children's word recognition. Children in grades 3 and 5 were asked to complete a lexical decision priming task. Prime‐target pairs varied in semantic similarity, with low (e.g., belly‐bell), moderate (e.g., lately‐late), and high similarity relations (e.g., boldly‐bold). There were also word pairs similar in form only (e.g., spinach‐spin) and in semantics only (e.g., garbage‐trash). Primes were auditory and targets were presented visually. Analyses of children's lexical decision times revealed graded priming effects as a function of the convergence of form and meaning. These results indicate that developing readers do not necessarily need to lexicalize morphological units to facilitate word recognition. Their ability to process the morphological structure of words depends on their ability to develop connections between form and meaning.     

Estimating valence from the sound of a word: Computational,experimental, and cross-linguistic evidence

It is assumed linguistic symbols must be grounded in perceptual information to attain meaning, because the sound of a word in a language has an arbitrary relation with its referent. This paper demonstrates that a strong arbitrariness claim should be reconsidered. In a computational study, we showed that one phonological feature (nasals in the beginning of a word) predicted negative valence in three European languages (English, Dutch, and German) and positive valence in Chinese. In three experiments, we tested whether participants used this feature in estimating the valence of a word. In Experiment 1, Chinese and Dutch participants rated the valence of written valence-neutral words, with Chinese participants rating the nasal-first neutral-valence words more positive and the Dutch participants rating nasal-first neutral-valence words more negative. In Experiment 2, Chinese (and Dutch) participants rated the valence of Dutch (and Chinese) written valence-neutral words without being able to understand the meaning of these words. The patterns replicated the valence patterns from Experiment 1. When the written words from Experiment 2 were transformed into spoken words, results in Experiment 3 again showed that participants estimated the valence of words on the basis of the sound of the word. The computational study and psycholinguistic experiments indicated that language users can bootstrap meaning from the sound of a word.
