基于神经学方法的运用,情绪、情绪调节研究发现事件相关电位的晚正成分LPP与情绪刺激的自动化加工、有意控制加工之间有着紧密的联系。LPP源于枕叶和后顶叶皮层,由蓝斑——去甲肾上腺素系统对情绪刺激进行反应时产生,反映了注意对情绪刺激的持续偏向和加工。由于个体生活经历、年龄发展及基因的不同,LPP存在个体差异性。情绪调节的ERP研究发现,LPP的时程可作为情绪调节的替代指标。在此基础上,提出ERP在较完整理解情绪加工和调节这一应用领域中的未来发展方向。  相似文献

韵律特征对语法建构的影响是心理语言学和认知神经科学的重要研究内容。韵律信息不仅可以帮助口语理解,而且文本阅读时也要借助韵律特征。为了揭示韵律加工的时间进程和脑机制,研究者使用事件相关电位(ERP)技术取得了一些重要的研究成果。首先,总结了韵律特征和语法结构相互作用过程中可能出现的六个ERP成分:右前负波(RAN)、早期负波(EN)、失配性负波(MMN)、中止正移波(CPS)、P600和P800。其次,针对目前研究韵律加工的特异性成分的不一致、实验任务不符合正常阅读习惯的缺陷、缺乏系统整合性分析这三个问题与争论进行了讨论。最后提出,只有充分考虑包括测试点、被试完成的任务等因素的影响,才能促进语言脑机制研究的进展。  相似文献

隐喻语言理解的语用和心理语言学阐释   总被引:4,自引:0,他引:4  
语言学家对隐喻语言的理解有不同的解释。语用学家认为,隐喻语言违反了话语交际准则,对隐喻语言的理解包含对语用含意的一系列推导,其理解是间接的。心理语言学家认为,隐喻是人们对日常知识和经验概念化的一种手段,反映了人们较为普遍的思维和认知方式,对隐喻语言理解并不需要特殊的认知过程。从多学科、多角度对隐喻语言进行研究讨论,将使我们对隐喻语言理解获得更深更全面的认识。  相似文献

This study compared how lexical quality (vocabulary and decoding) and executive control (working memory and inhibition) predict reading comprehension directly as well as indirectly, via syntactic integration, in monolingual and bilingual fourth grade children. The participants were 76 monolingual and 102 bilingual children (mean age 10 years, SD = 5 months) learning to read Dutch in the Netherlands. Bilingual children showed lower Dutch vocabulary, syntactic integration and reading comprehension skills, but better decoding skills than their monolingual peers. There were no differences in working memory or inhibition. Multigroup path analysis showed relatively invariant connections between predictors and reading comprehension for monolingual and bilingual readers. For both groups, there was a direct effect of lexical quality on reading comprehension. In addition, lexical quality and executive control indirectly influenced reading comprehension via syntactic integration. The groups differed in that inhibition more strongly predicted syntactic integration for bilingual than for monolingual children. For a subgroup of bilingual children, for whom home language vocabulary data were available (n = 56), there was an additional positive effect of home language vocabulary on second language reading comprehension. Together, the results suggest that similar processes underlie reading comprehension in first and second language readers, but that syntactic integration requires more executive control in second language reading. Moreover, bilingual readers additionally benefit from first language vocabulary to arrive at second language reading comprehension.  相似文献

Electrophysiology studies have identified two event‐related potentials that are modulated by predictive processes during language comprehension: the N400 and a frontal positivity. The N400 is smaller when words are presented within highly restrictive sentences, indicating reduced lexical retrieval costs. Violations of strong predictions generate larger frontal positivities, possibly reflecting inhibitory processes. More skilled comprehenders may exhibit enhanced predictive processing, but this possibility has seldom been investigated with event‐related potentials (ERPs). We analyzed the association between predictability ERP modulations and reading comprehension abilities. Twenty‐four undergraduate students were exposed to strongly and weakly constraining sentences, ending with an expected or unexpected final word. Their comprehension skills were assessed with a cloze task. Better comprehenders showed smaller N400s for expected words, and larger posterior positivities for unexpected endings, in strongly constraining contexts. These effects correlated with reading comprehension scores. The results suggest that better comprehenders take more advantage of predictions to reduce retrieval costs, and allocate more resources to postlexical integration processes.  相似文献

We examined theoretical issues concerning the development of reading fluency and language proficiency in 390 English Language Learners (ELLs,) and 149 monolingual, English-as-a-first language (EL1) students. The extent to which performance on these constructs in Grade 5 (i.e., concurrent predictors) contributes to reading comprehension in the presence of Grade 2 autoregressors was also addressed. Students were assessed on cognitive, language, word reading, and reading fluency skills in Grades 2 and 5. In Grade 2, regardless of language group, word and text reading fluency formed a single factor, but by Grade 5 word and text reading fluency formed two distinct factors, the latter being more aligned with language comprehension. In both groups a substantial proportion of the variance in Grade 5 reading comprehension was accounted for uniquely by Grade 2 phonological awareness and vocabulary. Grade 5 text reading fluency contributed uniquely in the presence of the autoregressors. By Grade 5 syntactic skills and listening comprehension emerged as additional language proficiency components predicting reading comprehension in ELL but not in EL1. Results suggest that predictors of reading comprehension are similar but not identical in ELL and EL1. The findings point to a more nuanced and dynamic framework for understanding the building blocks that contribute to reading comprehension in ELLs and EL1s in upper elementary school. They underscore the importance of considering constructs such as vocabulary, whose role is stable, and other components of language proficiency and reading fluency whose role becomes pivotal as their nature changes.  相似文献

Language comprehension is crucial to reading. However, theoretical models and recent research raise questions about what constitutes this multifaceted domain. We present two related studies examining the dimensionality of language comprehension and relations to reading comprehension in the upper elementary grades. Studies 1 (Grade 6; N = 148) and 2 (Grade 3–5; = 311) contrasted factor models of language comprehension using item level indicators of morphological awareness and vocabulary (Studies 1 and 2) and syntactic awareness (Study 2). In both studies, a bifactor model—including general language comprehension and specific factors for each language component—best fit the data, and general language comprehension was the strongest predictor of reading comprehension. In Study 2, the morphology-specific factor also uniquely predicted reading comprehension above and beyond general language comprehension. Results suggest the value of modeling the common proficiency underlying performance on tasks designed to tap theoretically distinct language comprehension skills.  相似文献

There has been a considerable suggestion in the literature that syntactic adaptation of a text would simplify it. This empirical study determined that the complexity of the syntax does not significantly affect the level of reading comprehension. While a complete conceptual and lexical analysis may be necessary for reading comprehension, a thorough syntactic analysis is not. This should be true for both expert and novice readers in a particular professional field, herein computer science. Using American (L1 or E1, English as a native language) and Dutch (L2 or E2, English as a second, nonnative language) computer science and humanities majors reading in EST (English for Science and Technology), it was found that there were no significant differences between subgroups reading an authentic (in original, unadapted form) computer science text and those reading a syntactically adapted text either in comprehension or in time across the four groups of subjects. These results indicate that syntactic simplification of an EST text is not a real simplification. Hence, technical writers and EST teachers might give priority to other more conceptual ways of rewriting texts.  相似文献

This study explored whether children's second language (L2) vocabulary, syntactic awareness, and reading comprehension contributed to the growth of each other. A total of 184 Chinese primary school children (91 girls) aged 8–10 years old in Hong Kong participated in the pre-test of this study. Among them, 88 were in Grade 3 and 96 were in Grade 4. One year later, 178 of these children also participated in the post-test. These children learned English as an L2 at school. They completed a series of English language tasks. The results from a cross-lagged panel model show that vocabulary predicted the growth of syntactic awareness and reading comprehension. Syntactic awareness predicted the growth of vocabulary and reading comprehension. Reading comprehension facilitated the growth of vocabulary, and it also predicted the growth of syntactic awareness in Grade 4 students but not in Grade 3 students. Implications for teaching children an L2 are discussed.  相似文献

Hearing loss during the critical period for language acquisition restricts spoken language input. This input limitation, in turn, may hamper syntactic development. This study examined the comprehension, production, and repetition of Wh-questions in deaf or hard-of-hearing (DHH) children. The participants were 11 orally trained Hebrew-speaking children aged 9.1-12.4 with moderate-to-profound hearing loss from birth, who consistently used hearing aids or cochlear implants and who had difficulties understanding relative clauses. Experiment 1 tested the comprehension of Wh-questions using a picture selection task, comparing subject with object questions and who- with which-questions; Experiment 2 tested the production of subject and object who-questions using an elicitation task; and Experiment 3 tested the repetition of Wh-questions and other structures derived by Wh-movement. All the DHH participants showed difficulty in the comprehension, production, and repetition of object questions, and their performance was significantly below that of hearing children. In contrast, they repeated embedded sentences without movement well, indicating that their deficit is in syntactic movement rather than embedding or the CP node in the syntactic tree. The results provide additional evidence that DHH children have difficulties with Wh-movement and emphasize that Wh-questions, which are crucial for communication, can be severely impaired in these children.  相似文献

Direct instruction reading programs have been found to be a successful way to teach reading to many, but not all, students with learning disabilities. This study investigated whether reading improvement for students with learning disabilities receiving reading instruction through a direct instruction reading program might be related to their language abilities. The reading progress of 26 students (19 male, 7 female), 7 to 10 years old, was measured over 2 years. In addition, phonological and syntactic abilities were assessed. The results indicated that phonological ability was related to progress in word attack skills and that syntactic ability was related to improvement in comprehension skills. These results have implications for the reading instruction of students with learning disabilities.  相似文献
