The role of the ventral and dorsal pathways in reading Chinese characters and English words

Previous literature in alphabetic languages suggests that the occipital-temporal region (the ventral pathway) is specialized for automatic parallel word recognition, whereas the parietal region (the dorsal pathway) is specialized for serial letter-by-letter reading ( [Cohen et al., 2008] and [Ho et al., 2002] ). However, few studies have directly examined the role of the ventral and dorsal pathways in Chinese reading compared to English reading. To investigate this issue, we adopted the degraded word processing paradigm used by Cohen et al. (2008) and compared brain regions involved in the processing of degraded Chinese characters and English words during lexical decision, using functional magnetic resonance imaging (fMRI). The degraded characters/words were created by inserting blank spaces between radicals of Chinese characters or syllables of English polysyllabic words. Generally, the current study replicated the effects of Cohen et al. (2008), showing that in Chinese – like in alphabetic languages – character spacing modulates both ventral (bilateral cuneus, left middle occipital gyrus) and dorsal (left superior parietal lobule and middle frontal gyrus) pathways. In addition, the current study showed greater activation in bilateral cuneus and right lingual gyrus for Chinese versus English when comparing spaced to normal stimuli, suggesting that Chinese character recognition relies more on ventral visual-spatial processing than English word recognition. Interestingly, bilateral cuneus showed monotonic patterns in response to increasing spacing, while the rest of the regions of interest showed non-monotonic patterns, indicating different profiles for these regions in visual-spatial processing.     

Rater Wealth Predicts Perceptions of Outgroup Competence

National income has a pervasive influence on the perception of ingroup stereotypes, with high status and wealthy targets perceived as more competent. In two studies we investigated the degree to which economic wealth of raters related to perceptions of outgroup competence. Raters’ economic wealth predicted trait ratings when (1) raters in 48 other cultures rated Americans’ competence and (2) Mexican Americans rated Anglo Americans’ competence. Rater wealth also predicted ratings of interpersonal warmth on the culture level. In conclusion, raters’ economic wealth, either nationally or individually, is significantly associated with perception of outgroup members, supporting the notion that ingroup conditions or stereotypes function as frames of reference in evaluating outgroup traits.     

汉字认知过程中整字对部件的影响

英文研究中,"字优效应"是单词促进字母加工的一个重要依据。但中文研究中还存在一些争议。本研究通过两个实验考查了汉字的部件认知中,汉字整体对局部(部件)的影响。实验刺激材料分为三种,即左右结构或上下结构的真字、假字与部件字。目标部件为既能够放置于三种字符的左侧,又能放置于右侧(上部或下部)的汉字部件。实验一采用Reicher-Wheeler实验任务,先呈现刺激材料350ms,掩蔽后再呈现需要判断的目标部件,被试对目标部件进行按键反应。实验二中采用部件判断实验任务,先呈现需要判断的目标部件,再呈现刺激材料,被试对刺激材料中是否包含目标部件进行按键反应。记录反应时与正确率。27位健康女性大学生参与本实验。结果显示:(1)不论是Reicher-Wheeler实验任务还是部件判断实验任务,均显示部件字的部件认知判断速度最快。真字与假字相比,无"字优效应"。真字与部件字相比,存在着"字劣效应"。这些结果表明,汉字整字对汉字部件认知加工起到抑制作用;(2)两个实验任务均表现出汉字结构方式效应,即对左右结构的汉字的部件认知比上下结构的汉字更快;(3)部件的空间位置对部件识别存在影响。实验一中对下部件分辨最困难,分辨时间最长;实验二中发现对左部件的反应最快。字符结构方式效应与部件空间位置效应既存在于真字中,也存在于假字中。     

儿童家庭读写活动、早期读写水平与小学一年级语文课成绩的关系

从读写萌发的观点出发,探讨6至7岁儿童的家庭读写活动、早期读写水平与其在校语文成绩的关系。研究结果显示:在控制儿童的非言语智力和父母的教育水平等变量后,(1)只有儿童的非正式家庭读写活动能够显著预测其口头词汇;(2)只有儿童的正式家庭读写活动能够显著预测其识字量;(3)只有儿童入学时的识字量能够显著预测他们一年级时的语文成绩和平时语文课表现;(4)儿童的口头词汇和家庭读写活动均无法预测其在校的语文课成绩。     

Submission, inhibition and sexuality: Masochistic character and psychic change in Austen's Mansfi eld Park

Mansfield Park is Austen's most controversial novel. 'Squarely taking on such issues as class, gender, sexuality, religion, education, theatricality, and colonialism, Mansfield Park now appears to occupy a more critical place in Austen's canon and in literary and cultural history generally than that perennial favorite, Pride and prejudice' (Johnson, 1998, p. xiii). Austen's heroine, Fanny Price has generated heated controversy because of the provocative contradictions in her character, which this paper argues tally with the psychoanalytic understanding of moral masochism within the masochistic character. As a child neglected at home and then sent to a frightening new environment, in which she was lowest and last, Fanny Price needed the love and protection even of those who mistreated her. She needed to control and influence them with submission and the inhibition of her aggressive impulses and through a vigilant scrupulousness. Austen created a plot in which she also dramatized the seeds of change that lie within the submissive character, within the repressed and inhibited psychosexual desire linked to the father which can drive the reemergence of wishes for love and satisfaction in situations of relative safety.     

Using the Implicit Association Test does not rule out an impact of conscious propositional knowledge on evaluative conditioning

Implicit measures such as the Implicit Association Test (IAT) have recently become popular as tools in research on evaluative conditioning. The reason is that these measures are thought to be impervious to changes in valence that are due to conscious propositional knowledge about the relation between the conditioned stimulus (CS) and the unconditioned stimulus (US). I present data that raise doubts about the validity of this assumption. In two experiments, attitudes towards CSs as measured by the IAT were in line with instructed CS-US contingencies even though the CSs and USs were never actually paired. The results therefore suggest that IAT effects can be biassed by conscious propositional knowledge.     

Practical Wisdom: Aristotle meets Positive Psychology

The strengths and virtues identified by positive psychology are treated as logically independent, and it is recommended that people identify their “signature” strengths and cultivate them, because more of a strength is better [Peterson and Seligman: 2004, Character Strengths and Virtues: A Handbook and Classification (Oxford University Press, New York); Seligman: 2002, Authentic Happiness (Free Press, New York)]. The present paper contrasts that view with the Aristotelian view that virtues are interdependent, that happiness (eudaimonia) requires all the virtues, and that more of a virtue is not always better than less. We argue that practical wisdom is the master virtue essential to solving problems of specificity, relevance, and conflict that inevitably arise whenever character strengths must be translated into action in concrete situations. We also argue that practical wisdom is becoming increasingly difficult to nurture and display in modern society, so that attention must be paid to reshaping social institutions to encourage the use of practical wisdom rather than inhibiting it.     

Convergence of Character Strengths in American and Japanese Young Adults

We investigated cultural influences on the distribution of character strengths, gender differences in character strengths, and the relationship of happiness to character strengths. Young adults from the United States (n=1099) and Japan (n=308) completed the English or Japanese versions of the Values in Action Inventory of Strengths. American and Japanese showed similar distributions of the 24 strengths measured: Higher strengths included love, humor and kindness, and lesser strengths included prudence, self-regulation, and modesty. Gender differences across cultures were also similar: Females were more likely than males to report strengths of love and kindness, whereas males were more likely to report bravery and creativity. In both samples, associations with happiness were found for zest, hope, curiosity and gratitude. The present study is a first step in an international study of character strengths, and we discuss the ubiquity and variation of character across culture.     

高、低频汉字形音义激活的时间进程

采用基于字形的启动范畴判断任务,通过变化SOA和不同的启动类型,考察高、低频汉字形音义激活的相对时间进程。结果表明,高频汉字形音义激活的时间顺序为字形—字义—字音;低频汉字字形的激活在先,字音、字义的激活时间未能分开。这说明汉字的书面使用频率是影响汉字形、音、义激活时间进程的重要因素。本研究进一步支持了汉字形—音、形—义连接强度受汉字使用频率影响的观点。     

中文阅读过程中字形快速启动的眼动研究

以字形相似的汉字为启动字,探讨字形信息激活在汉字识别中的时间进程。实验1采用命名任务考察三种启动时间条件下是否存在字形启动效应,结果发现当启动时间为35ms时,出现稳定的字形启动效应。实验2采用眼动记录法考察阅读过程中的快速启动,结果在三种启动时间条件下均未发现显著的启动效应。
