成年熟练读者的汉字读音加工过程 总被引:6,自引:2,他引:4
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。 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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。 相似文献

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. 相似文献
