汉、英工作记忆的加工和储存对中学生英语阅读理解的影响

本研究采用"视空间和言语交替"任务范式分离言语工作记忆的加工和储存两个成分,分别探讨了英语工作记忆的加工和储存成分对我国中学生英语阅读理解的作用及其途径,以及汉语工作记忆的加工和储存成分对中学生英语阅读理解是否具有跨语言影响。98名初中二年级学生完成了一般认知能力、英语阅读理解、汉语和英语工作记忆任务。结果表明:(1)英语工作记忆的加工和储存成分对英语阅读理解均有显著的独立预测作用;(2)英语工作记忆的储存成分对英语阅读理解的作用部分是由加工成分引起的;(3)汉语工作记忆的加工成分对英语阅读理解没有显著的直接预测作用,但却以英语工作记忆的加工成分为中介间接作用于英语阅读理解;汉语工作记忆的储存成分对英语阅读理解没有显著的预测作用。可见,言语工作记忆是一个多成分系统,加工和储存两个成分是相对分离的,并且它们具有不同的跨语言特性,加工存在跨语言一般性,而储存则具有语言特异性。     

惯用语理解的多种心理机制：不同的证据

惯用语的理解机制一直是心理语言学研究的热点问题。来自语言学和神经生理学的证据都表明,对惯用语的加工存在多样化趋势,而且加工策略和手段会随个体卷入社会生活的程度而变化。惯用语的加工受加工者自身的隐喻知识以及惯用语本身性质的影响。另外,惯用语加工激活的脑区表明句法和语义分析在惯用语理解中均发挥重要作用,惯用语并没有词汇化,但是不能使用统一的加工模型来整合惯用语的理解机制。惯用语自身性质的多样化导致惯用语理解的多种心理机制。     

抑制控制与高级认知功能的关系

近年来抑制控制与高级认知功能关系的研究受到了越来越多的重视。大量实证研究表明, 抑制控制是解释工作记忆、阅读理解、液态智力等高级认知功能个体差异的一个重要机制。脑成像研究表明, 抑制控制与工作记忆和液态智力等高级认知功能都激活了前额叶和顶叶等共同脑区。同时, 认知发展和认知老化, 以及认知干预领域的研究都一致表明, 抑制控制与高级认知功能关系密切。未来研究应注意抑制控制的定义和测量问题, 以及脑机制和训练干预等方面的问题。     

英语学习不良儿童语音能力与阅读理解的关系

探讨了英语学习不良儿童语音能力的发展状况,分析了这些儿童在英语学习中语音能力,句法意识及阅读理解能力间的关系。结果发现,除了在假词拼读能力上存在缺陷外,英语学习不良儿童在其他语音能力--英语语音意识、听觉言语工作记忆及视觉言语工作记忆上均不存在发展滞后现象;在对儿童的阅读理解能力进行预测时,假词拼读、语音意识、句法意识和听觉工作记忆是较好的预测效标。     

The relationship between morphological awareness and reading comprehension in Spanish‐speaking children

In the last decades, a series of studies has explored the role of morphological awareness on reading comprehension. Path analysis studies performed in English have shown that morphological awareness benefits reading comprehension both directly and indirectly, through word decoding. This issue has seldom been explored in Spanish. The aim of this study was to replicate in Spanish the results previously found in English. We used path analysis to assess three alternative models of the relationship between morphological awareness, word decoding and reading comprehension in 4th grade Spanish‐speaking children. Contrary to English, we found that morphological awareness benefits reading comprehension only directly. We conclude that in Spanish, in which accurate and fluent pronunciation of written words can be achieved through grapheme‐to‐phoneme conversion rules, morphological awareness does not help the correct pronunciation of words. Thus, morphological awareness is not relevant for word decoding in Spanish but is related to reading comprehension since this type of morphological knowledge provides access to the semantic and syntactic information of new words.     

小学儿童词汇知识与阅读理解的关系：交叉滞后研究

对小学1、3、5年级共399名学生进行为期1年的追踪测查, 使用交叉滞后模型检验小学低、中、高年级儿童词汇知识与阅读理解的关系。在控制了语音意识、语素意识、一般认知能力和自回归效应之后, 结果发现：在小学低年级, 词汇知识与阅读理解之间未发现显著的纵向预测关系; 在中年级, 词汇知识和阅读理解存在显著的双向预测关系; 在高年级, T1的阅读理解能够显著预测T2的词汇知识, 而T1的词汇知识对T2阅读理解的预测作用不显著。研究结果表明词汇知识与阅读理解的关系在小学不同年级段存在不同的模式, 这一发现支持了阅读发展阶段论, 并对阅读三角理论进行了一定的补充。     

Socioeconomic background,nonverbal IQ and school absence affects the development of vocabulary and reading comprehension in children living in severe poverty

Few studies have examined how socioeconomic status (SES) affects two essential parts of human development, namely vocabulary and reading comprehension, in children facing severe poverty. The Roma population is the largest minority group in Europe, the majority of whom live in severe poverty. This study compared the development of 322 Roma children with the development of 178 non‐Roma children, between the ages of 7 and 10 years, living in Romania. The Roma children had poorer initial vocabulary and reading comprehension skills as well as slower growth rates for both compared to the non‐Roma children. Importantly, SES had a direct influence on growth in both reading comprehension and vocabulary. The effect of SES was partly mediated by school absence and nonverbal IQ. This is a powerful finding since it suggests that poverty may have detrimental effects not only on reading but also on the development of verbal abilities.     

社会观点采择与故事阅读的关系——字词认知的调节作用

以161名小学四年级（10岁）儿童为对象,探讨社会观点采择与故事阅读理解之间的关系。要求被试完成故事阅读理解测验,社会观点采择测验和字词认知测验。采用分层回归进行数据分析,结果发现：（1）被试的社会观点采择能力对阅读理解总分、直接理解、直接推论、诠释整合具有显著的预测作用,对检视评价的预测作用不显著;（2）字词认知调节社会观点采择对故事阅读理解成绩的预测作用。社会观点采择对故事阅读理解成绩的影响随着字词认知能力的减弱而增高。对于字词认知能力较低的儿童,社会观点采择在故事阅读理解中发挥更强的预测作用。     

重读对口语理解中时间选择性注意分配的影响

采用事件相关电位（ERP）技术来研究重读如何影响口语加工中早期的选择性注意分配。并进一步研究重读的这种注意调控作用是否受声调的影响。实验以单个句子为实验材料,结果发现重读比不重读条件下的关键词更早的引起一个早期负波（N1）,并且引起更大的N400。在两个时间窗口重读的效应都不受声调的调控。这些结果表明,在自然的口语理解过程中,重读能够快速的调控早期选择性注意的分配,并影响接下来的语义加工的深度。     

Metacognition and proofreading: the roles of aging,motivation, and interest

The current study examined younger and older adults’ error detection accuracy, prediction calibration, and postdiction calibration on a proofreading task, to determine if age-related differences would be present in this type of common error detection task. Participants were given text passages, and were first asked to predict the percentage of errors they would detect in the passage. They then read the passage and circled errors (which varied in complexity and locality), and made postdictions regarding their performance, before repeating this with another passage and answering a comprehension test of both passages. There were no age-related differences in error detection accuracy, text comprehension, or metacognitive calibration, though participants in both age groups were overconfident overall in their metacognitive judgments. Both groups gave similar ratings of motivation to complete the task. The older adults rated the passages as more interesting than younger adults did, although this level of interest did not appear to influence error-detection performance. The age equivalence in both proofreading ability and calibration suggests that the ability to proofread text passages and the associated metacognitive monitoring used in judging one’s own performance are maintained in aging. These age-related similarities persisted when younger adults completed the proofreading tasks on a computer screen, rather than with paper and pencil. The findings provide novel insights regarding the influence that cognitive aging may have on metacognitive accuracy and text processing in an everyday task.
