移动窗口条件下阅读过程中字词识别特点的研究

采用“移动窗口”技术对中文阅读过程中的字词识别进形了初步的探讨。被试是８名大学生,阅读材料为８篇科学文章。结果发现,在移动窗口条件下,词的注视时间受词频、词中字数等词本身特性,词在理解文章中的重要性以及句子界限效应、文章难度等来自阅读理解的高级过程的影响。移动窗口技术可以在一定程度上较真实地探讨阅读中字词的连续加工过程。     

插图在说明文阅读理解中的作用

研究的目的在于揭示插图对说明文阅读理解的影响。实验中使用移动窗口技术对阅读过程中插图的作用进行探讨,并考察空间想象能力在其中的作用。结果表明：１．插图可以改进说明文的阅读理解,提高阅读速度;２．插图可以帮助读者建立文章所描述物体的参照表征,在建立参照表征的过程中,插图有利于重要概念的理解和有关参照表征信息的整合;３．插图有助于空间想象能力低的读者理解重要概念以及整合有关信息。     

成年熟练读者的汉字读音加工过程

本研究对成年熟练读者的汉字读音过程作了初步探讨。被试为大学生,实验材料以形声字为主,研究方法使用命名潜伏期法。实验一研究了不同字形、不同字频的单个汉字的读音,发现被试读汉字有直接提取、声旁及类似推理三种加工方式。高频字的读音以提取为主;中频字读音时,声旁和类似推理的作用增加;低频字读音时提取基本不起作用。实验二中发现,声旁的发音一致性对低频字的读音影响很大。激活熟悉的类似字,以确定刺激字的读音,是低频字读音的一个重要方式。     

High fatigue and its associations with health and work related factors among female medical personnel at 54 hospitals in Zhuhai,China

The present study aimed to investigate the prevalence of fatigue and determine factors associated with fatigue in female medical personnel. Based on a cross-sectional study, a total of 1608 female medical personnel at 54 hospitals in Zhuhai, China were recruited by a multistage stratified cluster sampling method. The Symptoms Checklist-90-Revised and Chalder Fatigue Scale were used to assess psychiatric symptoms and fatigue, respectively. Data regarding demographic, health, and work related variables were also collected. Multivariate logistic regression model was constructed to determine the influencing factors of fatigue. Approximately 83% of participants had experienced fatigue in the past week. The risk of fatigue was higher in aged 30–39 years old than older or younger participants; Longer sleeping time predicted a lower prevalence of fatigue (OR = .35), while tense physician-patient relationship predicted a higher prevalence of fatigue (OR = 1.77). Depression (OR = 1.76) and anxiety (OR = 1.96) were found related to fatigue. Additionally, fatigue was associated with marital status, occupation, health related factors (exercise, regular diet, and health status), and work related factors (hospital rank and turnover intention). These study findings might facilitate development and implementation of targeted interventions and preventive measures.     

Vocabulary growth rate from preschool to school‐age years is reflected in the connectivity of the arcuate fasciculus in 14‐year‐old children

The acquisition of language involves the functional specialization of several cortical regions. Connectivity between these brain regions may also change with the development of language. Various studies have demonstrated that the arcuate fasciculus was essential for language function. Vocabulary learning is one of the most important skills in language acquisition. In the present longitudinal study, we explored the influence of vocabulary development on the anatomical properties of the arcuate fasciculus. Seventy‐nine Chinese children participated in this study. Between age 4 and age 10, they were administered the same vocabulary task repeatedly. Following a previous study, children's vocabulary developmental trajectories were clustered into three subgroups (consistently good, catch‐up, consistently poor). At age 14, diffusion tensor imaging data were collected. Using ROI‐based tractography, the anterior, posterior and direct segments of the bilateral arcuate fasciculus were delineated in each child's native space. Group comparisons showed a significantly reduced fractional anisotropy in the left arcuate fasciculus of children in the consistently poor group, in particular in the posterior and direct segments of the arcuate fasciculus. No group differences were observed in the right hemisphere, nor in the left anterior segment. Further regression analyses showed that the rate of vocabulary development, rather than the initial vocabulary size, was a specific predictor of the left arcuate fasciculus connectivity.     

Positive affect as a moderator of liking effects on trust and attraction

Attitude similarity effects on attraction appear to be mediated sequentially by positive affect, inferred attraction, and trust. That is, the first two supposedly distal mediators influence each other in building trust, a mediator proximal to attraction. However, the correlational nature of data reported heretofore precludes definitive conclusions about sequential dependency between the two distal mediators. In the research reported, therefore, the authors manipulated positive affect in the participants (Time 1) and liking of the partner for them (Time 2), and measured trust before attraction. As predicted, liking effects on trust and attraction were stronger when positive affect in the participants was high than when it was low. Importantly, the interaction effect in trust fully mediated the interaction effect in attraction.     

移植免疫学的新突破与器官移植

现代器官移植是建立在移植免疫学基础上,移植免疫学基础研究的每一个进展都推动了器官移植的发展。９０年代以来,Ｓｔａｒｚｌ提出了移植排斥的“双向移植排斥理论”,反映了在临床应用免疫抑制药物的情况下,移植排斥的特点,是移植免疫学发展史上的一个重要理论地临床器官移植耐受的诱导具有重要的指导作用。     

移动窗口条件下语音、字形信息在汉语阅读中的作用

采用移动窗口方法,初步探讨了音音、字形在汉语阅读中的作用。结果发现：在错词经一、二个字上,被度的阅读反应时加长;同音错词和形似错词同时引起反应时的增加;同音词引起的反应时增加效应消失得较早、较彻底,这表明：Ｔ上的汉语阅读理解过程中,（１）对语音和这形的加工是比较好时的;（２）语音和字形在正常阅读的字词识别早期同样起作用;（３）在在发现错误一,语音引导错误恢复的能力强于字形。     

The antinomy of science and democracy in modern China

Up to now Chinese academia has been addicted to inviting the twin goddesses of democracy and science, but has regrettably ignored the innate incongruity between them, which has led to the rise of scientism. May 4th pioneers first introduced this value system, but tension between these values subsequently led to a prevailing preference for science over freedom. The early Marxists defined freedom as obedience to social laws formulated in Marxist ‘science’, while Maoism finalized the Sinicization of Marxism with a belief in iron‐bound social laws and in human beings as mere political means, mercilessly suppressing any expression of free will.
