初中生英语词汇记忆策略的研究

通过对134名初中三年级学生英语词汇记忆策略的问卷调查以及记忆不同难度的词汇时所使用的策略的分析,发现初三学生以使用机械的、一般性的记忆策略为主;优生比差生更善于选用具体的词汇记忆策略;词汇记忆难度增大时,选择和使用多种策略的频率与人数有所增加。     

初中生英语词汇学习策略与英语成绩的相关研究

词汇是语言学习的基本单位。本研究使用《初中生词汇学习策略问卷》对江西省某中学99名初二学生的英语词汇策略使用现状进行了调查,并探讨了其与英语成绩的关系。结果表明,学生普遍持词汇最好是一遍一遍记的学习观念。在三种一级学习策略中,初中生较多地使用认知策略,尤其是其中的重复策略,这与其学习观念有关。英语学习成绩与词汇学习策略正相关,而且,成绩好的学生比成绩落后的学生有更好的学习策略。     

初一学生英语单词记忆策略的训练研究

在初一学生英语单词学习中引入关键词和概念归类策略训练,探讨了记忆策略的训练效果和自我效能对英语单词记忆的影响。结果发现：两种策略训练都能显著提高初一学生英语单词扇一效果相近;关键词策略训练可显著提高低自我效能被试的自我效能感;记忆自我效能对英语单词记忆行为有显著影响,高自我效能被试在训练后英语单词记忆成绩更好。     

情绪调节对大学生英语词汇记忆的影响

采用3(情绪调节策略:认知重评、表达抑制、无策略)×3(英语词汇性质:积极、中性、消极)的混合实验设计,考察在诱发负性情绪条件下,采用不同情绪调节策略对大学生记忆不同性质英语词汇的影响。结果表明:两自变量对英语词汇的再认和回忆主效应均显著,交互作用也显著,使用情绪调节策略被试的词汇再认和回忆成绩优于无策略组,但使用认知重评和表达抑制两种策略的被试在再认和回忆成绩上无显著差异;认知重评和无策略组对中性词汇的回忆成绩均优于积极和消极词汇。结果说明情绪调节对大学生的英语词汇记忆成绩有不同影响。     

词汇学习中“快速映射”现象的机制

词汇学习对于语言获得及有关认知能力发展有重要意义.通过考察儿童词汇的快速增长,研究者提出词汇学习涉及一个"快速映射"(fast mapping)过程.最近20多年,大量研究者考察了快速映射机制.一类研究者认为儿童依靠一些认知偏向来猜测新单词的意义;另一类研究者认为词汇频率、言语最末位置等语言环境因素影响该过程.最新研究趋向(如生成联合模型和词汇学习的贝叶斯推理模式)认为这两类因素都很重要,但对它们的作用时间和比重等仍有争议.     

儿童策略的"利用缺陷"研究

“利用缺陷”是策略发展的一个关键阶段,该文从它的定义、存在证据、产生原因、发展过程等方面分析了策略“利用缺陷”的研究现状,并着重从记忆容量、知识基础、元记忆等发展性因素,智力、归因等个体性因素和训练条件等外部因素探讨了策略“利用缺陷”产生的原因,并对未来研究提出了展望。     

新课程背景下高中英语词汇教学的有效性策略探析

词汇是语言的基本要素之一,离开了词汇,语言就失去了实际意义.词汇量是影响语言交际的根本因素,词汇教学是中学英语教学中的重要环节.本文旨在从探讨目前高中英语词汇教学过程中存在的问题及成因入手,建构新课程背景下英语词汇教学的有效性策略,以提高学生的词汇能力,为培养学生的英语综合运用能力夯实基础.     

词汇决定任务评析

词汇决定任务是字词识别研究中使用最多的任务之一。为了更好地利用它,本文对该任务作了详细地分析,一方面承认可以用词汇决定任务来研究词汇通达过程,另一方面又指出,它会受到策略因素的影响,研究者必须加以重视。     

学习成绩差与成绩好学生短时记忆特点的比较研究

本研究比较了小学１、３、５年级学习成绩好／差学生在图片、数字、词汇记忆上的特点。结果表明：（１）在图片记忆上,两组儿童的成绩没有差异。１、３年级优差生间的差异主要在数字与具体词汇记忆中;５年级两组学生的差异主要在数字与抽象词汇记忆中。（２）从提示／非提示及击中虚假刺激的结果看,两组儿童在记忆上的差异部分地是由于策略运用上的差异。经过提示,学习不良儿童在数字和词汇记忆上的成绩有了提高。     

学习判断及其准确性

学习判断是元认知判断的一种重要形式,是对未来记忆成绩的预测。产生机制及其准确性是学习判断研究的核心问题。研究者从不同的角度提出了多种理论,试图说明学习判断的机制与准确性。Koriat的线索模型总结了以往的研究发现,加深了人们对学习判断的理解,但该模型也面临着新的挑战。文章指出了已有研究中存在的问题及未来研究的方向。     

Alphabetic and nonalphabetic L1 effects in English word identification: a comparison of Korean and Chinese English L2 learners

Different writing systems in the world select different units of spoken language for mapping. Do these writing system differences influence how first language (L1) literacy experiences affect cognitive processes in learning to read a second language (L2)? Two groups of college students who were learning to read English as a second language (ESL) were examined for their relative reliance on phonological and orthographic processing in English word identification: Korean students with an alphabetic L1 literacy background, and Chinese students with a nonalphabetic L1 literacy background. In a semantic category judgment task, Korean ESL learners made more false positive errors in judging stimuli that were homophones to category exemplars than they did in judging spelling controls. However, there were no significant differences in responses to stimuli in these two conditions for Chinese ESL learners. Chinese ESL learners, on the other hand, made more accurate responses to stimuli that were less similar in spelling to category exemplars than those that were more similar. Chinese ESL learners may rely less on phonological information and more on orthographic information in identifying English words than their Korean counterparts. Further evidence supporting this argument came from a phoneme deletion task in which Chinese subjects performed more poorly overall than their Korean counterparts and made more errors that were phonologically incorrect but orthographically acceptable. We suggest that cross-writing system differences in L1s and L1 reading skills transfer could be responsible for these ESL performance differences.     

注意和记忆对孤独症儿童词汇发展滞后的影响

孤独症语言障碍的表现之一是词汇发展滞后, 可能与其注意和记忆损伤有关。当前研究结果表明, 孤独症儿童在学习词汇时难以利用社会注意提供的有效信息, 且其注意易受到无关刺激干扰, 这可能导致其形成的物体-词汇的联结不稳定, 影响其进一步将这种联结整合到心理词典并保存在记忆中。未来研究应探究联合注意影响孤独症儿童词汇学习的发展轨迹和机制, 儿童的词汇知识对其词汇记忆的影响, 并关注自然场景中孤独症儿童的词汇学习过程和个体差异。     

编码方式对陌生字形记忆的影响

采用学习-再认范式,分别以韩字、英文假词为实验材料,考察了编码方式对陌生字形记忆的影响。在学习阶段,通过随机呈现整体和部分探测刺激,引导被试分别以整体编码和部分编码方式学习陌生字形,并在学习结束后一小时进行再认记忆测试。结果发现,无论以韩字还是以英文假词为材料,部分编码条件的记忆成绩均显著好于整体编码。该结果说明部分编码相比于整体编码能促进陌生字形记忆,并且这种优势效应具有跨文字系统的一致性。     

Contrasting contributions of phonological short‐term memory and long‐term knowledge to vocabulary learning in a foreign language

The contributions of phonological short‐term memory and existing foreign vocabulary knowledge to the learning of new words in a second language were compared in a sample of 40 Greek children studying English at school. The children's speed of learning new English words in a paired‐associate learning task was strongly influenced by their current English vocabulary, but was independent of phonological memory skill, indexed by nonword repetition ability. However, phonological memory performance was closely linked to English vocabulary scores. The findings suggest that in learners with considerable familiarity with a second language, foreign vocabulary acquisition is mediated largely by use of existing knowledge representations.

Improving Migrant Students' Spelling of English and Spanish Words with Error Correction

We examined the effects of error correction on spelling accuracy of culturally and linguistically diverse students enrolled in summer Migrant Education. In an error correction strategy, students spelled a word, viewed a correct model, and corrected specific errors. In a traditional strategy, students wrote words three times each while viewing a correct model. Words were presented in Spanish or English. Results showed that students with and without learning disabilities, whose primary language was English, correctly spelled more English words in the error correction condition than the traditional. Students whose primary language was Spanish correctly spelled Spanish words equally well in both conditions, possibly because of the phonetic nature of the Spanish language.     

Lexical configuration and lexical engagement: When adults learn new words

People know thousands of words in their native language, and each of these words must be learned at some time in the person’s lifetime. A large number of these words will be learned when the person is an adult, reflecting the fact that the mental lexicon is continuously changing. We explore how new words get added to the mental lexicon, and provide empirical support for a theoretical distinction between what we call lexical configuration and lexical engagement. Lexical configuration is the set of factual knowledge associated with a word (e.g., the word’s sound, spelling, meaning, or syntactic role). Almost all previous research on word learning has focused on this aspect. However, it is also critical to understand the process by which a word becomes capable of lexical engagement—the ways in which a lexical entry dynamically interacts with other lexical entries, and with sublexical representations. For example, lexical entries compete with each other during word recognition (inhibition within the lexical level), and they also support the activation of their constituents (top-down lexical-phonemic facilitation, and lexically-based perceptual learning). We systematically vary the learning conditions for new words, and use separate measures of lexical configuration and engagement. Several surprising dissociations in behavior demonstrate the importance of the theoretical distinction between configuration and engagement.     

Common patterns of prediction of literacy development in different alphabetic orthographies

Previous studies have shown that phoneme awareness, letter-sound knowledge, rapid automatized naming (RAN), and verbal memory span are reliable correlates of learning to read in English. However, the extent to which these different predictors have the same relative importance in different languages remains uncertain. In this article, we present the results from a 10-month longitudinal study that began just before or soon after the start of formal literacy instruction in four languages (English, Spanish, Slovak, and Czech). Longitudinal path analyses showed that phoneme awareness, letter-sound knowledge, and RAN (but not verbal memory span) measured at the onset of literacy instruction were reliable predictors, with similar relative importance, of later reading and spelling skills across the four languages. These data support the suggestion that in all alphabetic orthographies, phoneme awareness, letter-sound knowledge, and RAN may tap cognitive processes that are important for learning to read.     

Cross-modal working memory binding and L1-L2 word learning

The ability to create temporary binding representations of information from different sources in working memory has recently been found to relate to the development of monolingual word recognition in children. The current study explored this possible relationship in an adult word-learning context. We assessed whether the relationship between cross-modal working memory binding and lexical development would be observed in the learning of associations between unfamiliar spoken words and their semantic referents, and whether it would vary across experimental conditions in first- and second-language word learning. A group of English monolinguals were recruited to learn 24 spoken disyllable Mandarin Chinese words in association with either familiar or novel objects as semantic referents. They also took a working memory task in which their ability to temporarily bind auditory-verbal and visual information was measured. Participants’ performance on this task was uniquely linked to their learning and retention of words for both novel objects and for familiar objects. This suggests that, at least for spoken language, cross-modal working memory binding might play a similar role in second language-like (i.e., learning new words for familiar objects) and in more native-like situations (i.e., learning new words for novel objects). Our findings provide new evidence for the role of cross-modal working memory binding in L1 word learning and further indicate that early stages of picture-based word learning in L2 might rely on similar cognitive processes as in L1.     

Strategy development and learning to spell new words: generalization of a process

The authors used microgenetic methods in 2 experiments to examine children's and adults' progress from initial attempts at spelling nonwords to later direct memory retrieval of the spellings. Participants repeatedly spelled nonwords presented in computerized, dictated-word spelling tests over several weeks. Following each spelling, participants provided retrospective strategy reports. Half of the children showed a gradual shift from spelling words with effortful backup strategies to fast retrieval; half of the children continued using backup strategies that were fast and effective for them. Relatively more adults shifted from backup strategies to retrieval, but otherwise their patterns of spelling development were quite similar to those of the children. This research provides support for the generalizability of the overlapping waves model to nonalgorithmic domains. It also demonstrates parallels between children and adults in learning to spell new words.
