汉语儿童英语口语词汇与阅读学习的关系

以120名四、五年级小学儿童为被试,探讨汉语儿童英语口语词汇与阅读学习的关系,并检验了英语语音意识在其中的中介作用。结果表明:(1)汉语儿童的英语口语词汇与阅读学习之间存在密切关系。控制一般认知能力和母语口语词汇的影响后,英语口语词汇对阅读学习仍具有显著的预测作用。其中,英语口语词汇产生对于英语单词认读的预测作用更重要,英语口语词汇理解则对英语单词理解的预测作用更重要。(2)英语口语词汇产生既可以直接作用于英语单词认读、理解和假词拼读,也部分通过英语语音意识的中介间接作用于英语阅读;英语口语词汇理解对英语单词理解也具有直接作用,并部分地通过英语语音意识的中介发挥间接作用     

A One-to-One Bias and Fast Mapping Support Preschoolers' Learning About Faces and Voices

A multimodal person representation contains information about what a person looks like and what a person sounds like. However, little is known about how children form these face-voice mappings. Here, we explored the possibility that two cognitive tools that guide word learning, a one-to-one mapping bias and fast mapping, also guide children's learning about faces and voices. We taught 4- and 5-year-olds mappings between three individual faces and voices, then presented them with new faces and voices. In Experiment 1, we found that children rapidly learned face-voice mappings from just a few exposures, and furthermore spontaneously mapped novel faces to novel voices using a one-to-one mapping bias (that each face can produce only one voice). In Experiment 2, we found that children's face-voice representations are abstract, generalizing to novel tokens of a person. In Experiment 3, we found that children retained in memory the face-voice mappings that they had generated via inference (i.e., they showed evidence of fast mapping), and used these newly formed representations to generate further mappings between new faces and voices. These findings suggest that preschoolers' rapid learning about faces and voices may be aided by biases that are similar to those that support word learning.

Why children learn color and size words so differently: evidence from adults' learning of artificial terms.

An adult simulation study examined why children's learning of color and size terms follow different developmental patterns, one in which word comprehension precedes success in nonlinguistic matching tasks versus one in which matching precedes word comprehension. In 4 experiments, adults learned artificial labels for values on novel dimensions. Training mimicked that characteristic for children learning either color words or size words. The results suggest that the learning trajectories arise from the different frames in which different dimensions are trained: Using a comparison (size-like) training regimen helps learners pick out the relevant dimension, and using a categorization (color-like) training regimen helps the learner correctly comprehend and produce dimension terms. The results indicate that the training regimen, not the meanings of the terms or the specific dimensions, determines the pattern of learning.     

Individuation and reference in memory: Proper names and definite descriptions

A theory is presented which assumes that individuals are represented by unique nodes in memory. To test the theory, simple facts were predicated of an individual person. Some facts referred to him by proper name, and other facts by his profession. In a before condition, subjects learned that the profession and name referred to the same individual before learning the facts, while in an after condition, they learned the identity after learning the facts. Subsequent to learning the facts and identities, subjects verified sentences based on what they had learned. Verification latencies indicated that in the before condition, one memory node was created to represent the individual, but two nodes were set up in the after condition. Assymmetries between proper names and professions indicate that the two types of referring expressions are treated differently in long-term memory.     

Young children's use of syntactic cues to learn proper names and count nouns

In 6 experiments, 144 toddlers were tested in groups ranging in mean age from 20 to 37 months. In all experiments, children learned a novel label for a doll or a stuffed animal. The label was modeled syntactically as either a count noun (e.g., "This is a ZAV") or a proper name (e.g., "This is ZAV"). The object was then moved to a new location in front of the child, and a second identical-looking object was placed nearby. The children's task was to choose 1 of the 2 objects as a referent for the novel word. By 24 months, both girls (Experiment 2) and boys (Experiment 5) were significantly more likely to select the labeled object if they heard a proper name than if they heard a count noun. At 20 months, neither girls (Experiments 1 and 6) nor boys (Experiment 1) demonstrated this effect. By their 2nd birthdays, children can use syntactic information to distinguish appropriately between labels for individual objects and those for object categories.     

Pre-existing Background Knowledge Influences Socioeconomic Differences in Preschoolers’ Word Learning and Comprehension

The goal of the current study is to explore the influence of knowledge on socioeconomic discrepancies in word learning and comprehension. After establishing socioeconomic differences in background knowledge (Study 1), the authors presented children with a storybook that incorporates this knowledge (Study 2). Results indicated that middle-income children learned significantly more words and comprehended the story better than lower-income children. By contrast, Study 3 presented children with a novel category and found that children performed equally in their word learning and comprehension. This suggests that socioeconomic differences in vocabulary and comprehension skills may be partially explained by differences in extant knowledge.     

Gavagai Is as Gavagai Does: Learning Nouns and Verbs From Cross‐Situational Statistics

Learning to map words onto their referents is difficult, because there are multiple possibilities for forming these mappings. Cross‐situational learning studies have shown that word‐object mappings can be learned across multiple situations, as can verbs when presented in a syntactic context. However, these previous studies have presented either nouns or verbs in ambiguous contexts and thus bypass much of the complexity of multiple grammatical categories in speech. We show that noun word learning in adults is robust when objects are moving, and that verbs can also be learned from similar scenes without additional syntactic information. Furthermore, we show that both nouns and verbs can be acquired simultaneously, thus resolving category‐level as well as individual word‐level ambiguity. However, nouns were learned more quickly than verbs, and we discuss this in light of previous studies investigating the noun advantage in word learning.     

小学低年级儿童阅读流畅性的发展轨迹及其对阅读理解的预测作用

对149名小学一年级儿童的阅读流畅性进行历时三年五次的追踪测试,采用潜变量增长模型探索了儿童阅读流畅性的发展轨迹,并在控制相关变量后,考察了阅读流畅性的起始水平和发展速度对阅读理解的预测作用。结果发现：（1）小学低年级儿童字词阅读流畅性呈非线性发展,其中一年级快速发展,二、三年级时进一步发展,但发展速度变缓,起始水平低的儿童其后发展速度快,表现出补偿模式;句子阅读流畅性呈线性发展,儿童个体之间的差异随时间逐渐增大,表现出马太效应;（2）控制一般认知能力、家庭社会经济地位及相关语言认知技能后,字词阅读流畅性的起始水平和发展速度均可预测儿童三年级时阅读理解水平,而句子阅读流畅性的起始水平不能预测,但发展速度有显著预测作用。结果说明字词阅读流畅性和句子阅读流畅性有不同的发展轨迹和发展模式,在小学低年级阶段,相比句子阅读流畅性,儿童字词阅读流畅性的起始水平对阅读理解有预测作用,且两者的发展速度均对阅读理解有预测作用。     

Metacognitive errors contribute to the difficulty in remembering proper names

While prior research has shown that proper names are more challenging to learn and remember than other types of information (e.g., occupations), little research has explored the role of metacognitive factors in proper name learning. Thus in four experiments participants learned, made predictions, and were tested on their memory for common nouns (i.e., occupations) and proper nouns (i.e., names). Results showed that memory predictions were consistently overconfident for names, whereas the discrepancy between predictions and performance was smaller for occupations. With experience, participants were able to modify predictions and, critically, Experiment 4 showed that improvements in the accuracy of memory predictions led participants to allocate more study time to names and thus improved memory for names. Such data suggest that theories of proper name learning should make provisions for deficits in metacognitive awareness.     

Lexical‐processing efficiency leverages novel word learning in infants and toddlers

Children who rapidly recognize and interpret familiar words typically have accelerated lexical growth, providing indirect evidence that lexical processing efficiency (LPE) is related to word‐learning ability. Here we directly tested whether children with better LPE are better able to learn novel words. In Experiment 1, 17‐ and 30‐month‐olds were tested on an LPE task and on a simple word‐learning task. The 17‐month‐olds’ LPE scores predicted word learning in a regression model, and only those with relatively good LPE showed evidence of learning. The 30‐month‐olds learned novel words quite well regardless of LPE, but in a more difficult word‐learning task (Experiment 2), their LPE predicted word‐learning ability. These findings suggest that LPE supports word‐learning processes, especially when learning is difficult.     

Children and adults represent proper names as referring to unique individuals

Adults represent proper names (e.g. ‘Katharine Hepburn’) as referring to unique individuals (i.e. Katharine Hepburn), and studies of children’s proper name learning have been taken to show that children represent proper names in like manner. However, almost all of these studies leave open the possibility that children represent proper names as referring to restricted kinds of highly similar animals. We provide direct evidence against this possibility: both adults and 3‐year‐old children presented with a novel word for a toy animal (e.g. ‘daxy’) assumed that the animal continued to be referred to with the word, despite a change in the animal’s appearance and location, and despite the introduction at the old location of an animal identical in appearance to the original animal at the time the word was introduced. Participants presented with a simple artifact (e.g. a bottle) did not interpret the word as a proper name, consistent with previous work.     

Towards a unitary account of access dysphasia: A single case study

Abstract

We report the case of a patient, H.E.C., with a profound verbal comprehension impairment. His comprehension impairment involved both common names (animal and inanimate items) and proper names. Within the proper name category, his comprehension of country and famous peoples' names was better than his comprehension of common forenames. By using matching to sample techniques, H.E.C.'s impairment was found to be affected by presentation rate and by semantic relatedness, but not by word frequency. An analysis of his responses showed marked inconsistency and serial position effects (i.e. a decrement of performance on subsequent presentations of the same items). H.E.C.'s comprehension deficit was interpreted in terms of an “access” impairment within the word-meaning system. A unitary account of this impairment in terms of a deficit that delays the return, following activation, of the set of representations underlying a word, to a “ready state” is proposed.     

汉语儿童词语结构意识在阅读理解中的预测作用

以382名小学一、三、五年级学生为被试,进行为期一年的追踪研究,通过分层回归,探索了词语结构意识在儿童阅读理解中作用的发展性变化。结果发现：（1）在控制了性别、瑞文推理、汉字识别、口语词汇以及快速命名和语音意识之后,在三年级T2、五年级和五年级T2发现了词语结构意识对同期阅读理解有独特解释作用,而在一年级、一年级T2和三年级均未发现词语结构意识对同期阅读理解的独特贡献;（2）在控制了性别、瑞文推理、自回归效应以及其他相关变量的作用后,三年级和五年级时的词语结构意识分别对一年后的阅读理解具有独特的预测作用。结果表明,在小学低年级阶段,词语结构意识在阅读理解中的作用还未显现,在小学中高年级阶段,词语结构意识对儿童阅读理解有显著的预测作用。     

Two-year-olds learn novel nouns,verbs, and conventional actions from massed or distributed exposures

Two-year-old children were taught either 6 novel nouns, 6 novel verbs, or 6 novel actions over 1 month. In each condition, children were exposed to some items in massed presentations (on a single day) and some in distributed presentations (over the 2 weeks). Children's comprehension and production was tested at 3 intervals after training. In comprehension, children learned all types of items in all training conditions at all retention intervals. For production, the main findings were that (a) production was better for nonverbal actions than for either word type, (b) children produced more new nouns than verbs, (c) production of words was better following distributed than massed exposure, and (d) time to testing (immediate, 1 day, 1 week) did not affect retention. A follow-up study showed that the most important timing variable was the number of different days of exposure, with more days facilitating production. Results are discussed in terms of 2 key issues: (a) the domain-generality versus domain-specificity of processes of word learning and (b) the relative ease with which children learn nouns versus verbs.     

The name game: acceptability,bonus information and group size

Our previous research demonstrated the effectiveness of the name game when learning the names of group members. In three experiments we conclude our study of the name game by demonstrating that it is very acceptable to participants and successful with larger groups. Experiment 1 compared the simple and elaborate name games. In the latter, participants learned a word provided by each person in addition to their full name. This ‘bonus’ information was very well learned without detriment to the name learning. Participants rated both versions of the name game as a good use of time and worth playing again although the elaborate name game was rated as more fun. Experiments 2 and 3 used the name game with groups of around 25, finding very good recall of full names. The role of retrieval in the effectiveness of the name game was again demonstrated to be essential. Copyright © 2004 John Wiley & Sons, Ltd.     

Comparisons of models of associative recall

We tested three mathematical models of associative recall that differ in the assumed structure of the memory trace (direct or indirect connections between parts) and the interdependence of the connections (independent or correlated). The three models compared are the “horizontal” model with direct, independent connections, the “schema” model with indirect, independent connections, and the “fragment” model with indirect, correlated connections. In Experiment 1, subjects studied quartets of minimally related words and then recalled, using one or two words of each quartet as cues. The horizontal and schema models predicted the data very well, but the fragment model did poorly. In Experiment 2, related word quintets were learned, and recall cues contained one, two, or three words of a quintet. Only the schema model adequately fit these data. Experiment 3 directly tested the fragment model, using sequential tests of unrelated word quartets. Even an augmented fragment model with extra recall failure parameters was decisively rejected by these data. Both the horizontal and schema models gave satisfactory qualitative accounts, although poor quantitative fits. A means of deriving the models through a spreading activation semantic network of preexperimental knowledge is suggested, and related models are discussed.     

The Influence of Learning Style and Cognitive Ability on Recall of Names and Faces in an Older Population

The present study examined whether, for older adults, a verbal or imagery cognitive style is associated with recall of names and faces learned in an experimental condition. Cognitive abilities that are represented in current models of face recognition and name recall were also examined. Those abilities included picture naming, verbal fluency (i.e., naming items within a given category), vocabulary comprehension, visual memory, and the learning of unassociated word pairs. Fifty older adults attempted to learn first and last names of 20 student actors and actresses pictured on videotapes (40 names total). On average, participants learned the most first names, followed by last names, and the fewest full names. The greater the number of responses on a questionnaire associated with an imagery cognitive style, the more the names of faces were correctly identified by participants. There was no significant relationship between a verbal cognitive style and the number of names and faces recalled. As for cognitive abilities, all of the abilities measured—with the exception of vocabulary comprehension—were significantly associated with the number of names and faces learned. A regression analysis indicated that the best predictor of successful name-face learning was the participants' ability to learn and recall 5 unrelated word pairs. When that cognitive measure was deleted from the regression analysis, delayed visual memory and verbal fluency were the next best predictors of the older adults' ability to learn names and faces.     

Naming and categorization in young children: IV: listener behavior training and transfer of function

Following pretraining with everyday objects, 14 children aged from 1 to 4 years were trained, for each of three pairs of different arbitrary wooden shapes (Set 1), to select one stimulus in response to the spoken word /zog/, and the other to /vek/. When given a test for the corresponding tacts ("zog" and "vek"), 10 children passed, showing that they had learned common names for the stimuli, and 4 failed. All children were trained to clap to one stimulus of Pair 1 and wave to the other. All those who named showed either transfer of the novel functions to the remaining two pairs of stimuli in Test 1, or novel function comprehension for all three pairs in Test 2, or both. Three of these children next participated in, and passed, category match-to-sample tests. In contrast, all 4 children who had learned only listener behavior failed both the category transfer and category match-to-sample tests. When 3 of them were next trained to name the stimuli, they passed the category transfer and (for the 2 subjects tested) category match-to-sample tests. Three children were next trained on the common listener relations with another set of arbitrary stimuli (Set 2); all succeeded on the tact and category tests with the Set 2 stimuli. Taken together with the findings from the other studies in the series, the present experiment shows that (a) common listener training also establishes the corresponding names in some but not all children, and (b) only children who learn common names categorize; all those who learn only listener behavior fail. This is good evidence in support of the naming account of categorization.     

That's More Like It: Multiple Exemplars Facilitate Word Learning

Previous research indicates learning words facilitates categorisation. The current study explores how categorisation affects word learning. In the current study, we investigated whether learning about a category facilitates retention of newly learned words by presenting 2‐year‐old children with multiple referent selection trials to the same object category. In Experiment 1, children either encountered the same exemplar repeatedly or encountered multiple exemplars across trials. All children did very well on the initial task; however, only children who encountered multiple exemplars retained these mappings after a short delay. Experiment 2 replicated and extended this finding by exploring the effect of within‐category variability on children's word retention. Children encountered either narrow or broad exemplars across trials. Again, all children did very well on the initial task; however, only children who encountered narrow exemplars retained mappings after a short delay. Overall, these data offer strong evidence that providing children with the opportunity to compare across exemplars during fast mapping facilitates retention. Copyright © 2013 John Wiley & Sons, Ltd.
