他人知识状态觉知对幼儿名词学习的影响

本研究采用两个实验考察了他人知识状态觉知对不同语言能力幼儿名词习得的影响。参加实验的被试是来自上海市三所幼儿园的89名3～4岁幼儿。实验一发现,高语言能力幼儿在确定和不确定两种实验条件下的名词习得有显著差异,确定条件下的得分高于不确定条件。一般语言能力幼儿未表现出上述区别;实验二进一步发现高语言能力幼儿能忽视表面的语气线索所表达的迟疑,影响他们词语学习的是对他人知识状态的深层觉知。     

学习考察德国紧急救援应急管理体系

德国的紧急救援应急体系结构合理,网络密集,分工明确,责任清晰,法制健全,管理先进,技术精良.特别是他们以人为本,尊重生命,未雨绸缪,防患于未然的理念;全民参与,平战结合,组织志愿者,从娃娃抓起的组织机构;合理分工,严谨、科学的态度更值得我们称道.为我们做好灾难应急救援工作提供了可以学习的经验和模式.     

文本阅读中概念提取的研究进展

文章对文本阅读中概念提取的研究进行了系统的介绍,虽然研究者得出了不同的结论,但都力图揭示文本阅读中概念提取的信息加工机制。文章在此基础上对影响文本阅读中概念提取的因素进行初步分析．发现文本类型、文本中心确定方式和抑制是主要因素。其中,文本中心确定方式是最主要的影响因素。     

汉语短时识别中的偏好效应

使用2-AFC任务,对汉语短时识别中的偏好效应进行研究。结果表明：汉语识别中存在偏好效应;偏好效应受词频变化的影响,高频时有更大的偏好效应;本实验的偏好效应不受启动词加工水平的影响,说明它是在一种纯的内隐记忆条件下产生的。     

职前教师与在职教师在算术应用题上真实性思考的研究

采用由7道真实性算术应用题构成的测试材料研究了117名职前教师和72名在职教师,首先要求被试解答这些题目,然后评定学生的不同答案。结果表明：1）职前教师与在职教师表现出真实性思考的多重性。2）我国职前教师被试的真实性思考的人数比例为87．5％,高于国外研究所报告的比例。3）在职教师的真实性思考、真实性解答的人数比例都高于职前教师,但没有达到显著性差异;不确定的真实性解答的人数比例极显著地高于职前教师;常规性解答的人数比例显著地低于职前教师。在评定学生解答时、在职教师更愿意接受“不确定”这样一个解题的逻辑性结果,职前教师对常规性解答的态度更为宽容。     

多义词意义间的联系程度对词汇判断时间的影响

采用词汇判断法,考察双字多义词各意义间的联系程度对词汇判断时间的影响,同时考察,意义间联系程度不同的多义词与单义词的词汇判断时间的关系。实验结果表明:汉语中双字多义词意义间联系程度的高低没有对多义词词汇判断的时间产生影响。在低频词的条件下,双字多义词,不管其意义间联系程度的高低,词汇判断的时间都快于单义词的判断时间,这表明汉语词汇识别中,存在低频多义词的识别优势效应。     

数学应用题中语言成分模型的构建—— 多元随机效应项目反应理论模型的运用

数学应用题中的语言成分可能对被试问题解决过程产生复杂影响。通常, 这种影响对所有被试并非完全一致, 而是具体数学题目特征与特定被试的认知特性之间交互作用的结果。本研究采用多元随机效应项目反应理论模型的建模方法, 分析了数学应用题中语言成分对问题解决过程的影响。该方法的优势在于它不仅分析了语言成分对数学问题解决过程的平均效应, 同时给出了相应的随机效应, 揭示了相应成分对不同个体问题解决过程的具体影响程度。结果表明, 较难的项目倾向于单词更多, 命题密度更高, 要求对图/表信息进行编码和转译, 或者根据问题表述生成数学公式。项目命题密度影响效应存在着显著的个别差异。项目命题密度对能力较低的被试的影响高于对能力较高的被试的影响。     

“上下意象图式”对汉语成语感情色彩加工的影响

通过两个实验,考察了＂上下意象图式＂对汉语成语感情色彩加工的影响。实验一发现,成语感情色彩加工存在＂隐喻一致效应＂,褒义的成语呈现在屏幕上方加工得更快,贬义的成语呈现在屏幕下方加工得更快、更准。实验二消除了具体空间信息的影响,发现仅有抽象符号水平的联结,＂上＂、＂下＂概念不能影响汉语成语感情色彩的加工。研究结果支持隐喻理论和具身认知观。     

The vocational well-being of workers with childhood onset of disability: Life satisfaction and perceived workplace discrimination

Workers with disabilities are understudied, and workers with childhood onset of disability have been excluded from many of the studies on disability and work that do exist. This research compares the effects of childhood and adult onset of disability in a nationally representative sample of workers with disabilities. Educational disruptions due to disability status in childhood are negatively associated with life satisfaction and positively associated with perceived discrimination. Although age is associated with increased life satisfaction and decreased perceptions of discrimination for workers with adult disability onset, age is unrelated to these outcomes for workers with childhood disability onset. Receiving workplace accommodations is positively associated with satisfaction and negatively associated with discrimination for both groups, however, these relationships are stronger in magnitude for the childhood disability onset group. Organizational environments, both in education and in the workplace, play a critical role in the vocational well-being of workers with childhood disability onset.     

Phonological priming and cohort effects in toddlers

Adult word recognition is influenced by prior exposure to phonologically or semantically related words (cup primes cat or plate) compared to unrelated words (door), suggesting that words are organised in the adult lexicon based on their phonological and semantic properties and that word recognition implicates not just the heard word, but also related words. We investigate the phonological organisation of the toddler lexicon with two experiments using a picture priming technique. Twenty-four month olds showed inhibition of target recognition in related primed trials compared to unrelated primed trials (Experiment 1) and also in related primed trials compared to unprimed trials (Experiment 2). Further analysis of children’s responding found that this inhibition effect was modulated by the cohort and neighbourhood size of the words tested. Overall, the results indicate a lexical basis for the reported effects and suggest that the phonological properties provide an organisational basis for words in the toddler lexicon.
