Research Findings: I examined the long-term association between the lexical and acoustic features of maternal utterances during book reading and the language skills of infants and children. Maternal utterances were collected from 22 mother–child dyads in picture book–reading episodes when children were ages 6–12 months and 5 years. Two aspects of language input were studied: lexical features (the amount and diversity of vocabulary, and the proportion of isolated target words) and an acoustic feature (the acoustic space of vowels). Standardized language tests were used to assess receptive vocabulary and language production abilities at age 5. The results showed that greater diversity of vocabulary and the use of fewer isolated target words during book reading with infants were associated with enhanced language skills in children 4 years later. Regression analyses showed that the proportion of isolated target words was the most potent predictor of, and acoustic vowel space also accounted for, variance in language expression skills at age 5. Maternal utterances and mothers' education jointly accounted for more than 60% of the variance in language abilities. Practice or Policy: These findings suggest that lexical and acoustic inputs in picture book reading with infants have long-term associations with children's language development throughout early childhood.  相似文献

位移体空间运动的参照,由“处所词”充当,按语义特征可分为“起点”、“经过点”和“终点”等。由介词标引的处所词,部分可以位于动词前,部分可以位于动词后,但有些介词结构位于动词前和动词后时。表义上往往不同。表示“起点”的处所词可以用介词结构置于动词前,表示“终点”的都不能用介词结构置于动词前,而可以由趋向词标引用于动词后。处所宾语语序基本遵循“起点在动词前,终点在动词后”的时空像似性,体现了人类普遍的“终端焦点化”的认知倾向。  相似文献

Compliance and Comprehension in Very Young Toddlers   总被引:1,自引:0,他引:1  
We studied the relation of compliance with comprehension in 30 toddlers, 10 each at 12–13, 14–16, and 17–18 months of age. Requests, using preselected words, were made to children in the context of a naturalistic and pleasant play situation in a quasilaboratory setting. Detailed coding systems were used to define comprehension, compliance, and patterns of compliance-comprehension, noncompliance-comprehension, compliance-noncomprehension, and noncompliance-noncomprehension at each age period. Findings indicated significant shifts in the categories of compliance-comprehension and noncompliance-noncomprehension across the 3 ages, with the most striking change occurring between 14–16 and 17–18 months. Implications of the data are discussed.  相似文献

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages.  相似文献

Toddlers' acquisition of the Novel Name–Nameless Category (N3C) principle was examined to investigate the developmental lexical principles framework and the applicability of the specificity hypothesis to relations involving lexical principles. In Study 1, we assessed the ability of 32 children between the ages of 16 and 20 months to use the N3C principle (operationally defined as the ability to fast map). As predicted, only some of the children could fast map. This finding provided evidence for a crucial tenet of the developmental lexical principles framewor: Some lexical principles are not available at the start of language acquisition. Children who had acquired the N3C principle also had significantly larger vocabularies and were significantly more likely to demonstrate 2-category exhaustive sorting abilities than children who had not acquired the principle. The 2 groups of children did not differ in either age or object permanence abilities. The 16 children who could not fast map were followed longitudinally until they attained a vocabulary spurt; at that time, their ability to fast map was retested (Study 2). Results provided a longitudinal replication of the findings of Study 1. Implications of these findings for both the developmental lexical principles framework and the specificity hypothesis are discussed.  相似文献

Young Children's Understanding of the Causes of Anger and Sadness   总被引:3,自引:0,他引:3  
This study investigated kindergarten children's understanding of the causes of anger and sadness. Previous research has shown that before 6 or 7 years of age, children have difficulty distinguishing hypothetical situations designed to evoke anger from those designed to evoke sadness. In this project, 80 kindergarten children (ages 5-1 to 6-5, M = 5-10) predicted and explained protagonists' emotional responses to a variety of hypothetical events. The results showed that intentional harm was not the feature young children used to distinguish anger from sadness. Children predicted anger most often when they believed that protagonists could change undesirable situations and reinstate their goals and when children focused on the person or conditions that brought about undesirable situations. Children predicted sadness most often when they believed that goal reinstatement was impossible and focused on the losses that would ensue as a result.  相似文献

Grade two through six elementary school Dutch children were asked to perform a lexical decision task including 90 pseudowords constructed by changing one or two letters in a Dutch word. Subsequently, the children were asked about the meaning of pseudowords they had not crossed out and that they, apparently, had considered to be words. Multiple regression analyses on the lexical decision task showed that the older children were more hindered by the morphemic structure of a pseudoword than by its orthographic neighbors. The younger children, in contrast, were less hindered by the morphemic structure of a pseudoword and more hindered by its orthographic neighbors. Word length was a (small) predictor only for grade 6. Moreover, the answers of the children reflected that in their construction of meanings for the pseudowords they were hindered both by the morphemic structure and by the orthographic neighbors of the pseudowords.  相似文献

Mothers' and Children's Conceptualizations of Corporal Punishment   总被引:2,自引:1,他引:2  
Preschool ( M age = 4–11) and fifth-grade ( M age = 12–1) children and their mothers judged the acceptability of corporal punishment as a function of the type of transgression (dangerous, violation of social rule, or violation of moral precept) and discipline agent. Children of both ages and their mothers discriminated among different types of transgressions as a function of rule contingency, rule generalizability, and seriousness of the transgression. Social convention transgressions were judged to be more rule contingent, less generalizable (across settings), and less serious than prudential (dangerous) or moral violations, but overall children judged transgressions to be more generalizable than did their mothers. Preschool children showed broad acceptability for severe corporal punishment given any type of transgression, by any agent, whereas fifth graders were generally discriminating about limits of punishability, and their judgments appeared to be transitional between the broad acceptance shown by younger children and more focused acceptability shown by mothers. Mothers were proprietary with respect to agent and tended to focus on dangerous and moral violations as punishable. Findings suggest a developmental path from a single criterion for young children to consideration of multiple criteria for older children and adults. Judgments were also interpreted as reflecting social roles such as parents' responsibility to constrain children and children's expectations for constraint. Preschool children's broad acceptability of punishment despite their differentiation of classes of rules and of transgressions suggests that different constraints operate for judgments about rules or commands as opposed to sanctions. Implications for children's ability to identify and report abuse are also noted.  相似文献

This study examined how moral judgments are applied to events in other cultures. It was hypothesized that subjects make both universal and relativistic judgments, contingent on the types of beliefs held in the culture to which the moral judgments were applied. It was furthermore expected that subjects would be both relativists and universalists at all ages. 72 subjects (aged 11–9, 15–10, and 21–3 years) were asked to apply moral judgments which they had made about a familiar context to 2 types of cultures, 1 where different informational beliefs were held and 1 where different moral beliefs were held. The results confirmed the hypotheses. Most subjects, at all ages, contextualized their moral judgments when they applied them to cultures with different informational beliefs but made nonrelativistic judgments with respect to cultures with opposing moral beliefs. Furthermore, subjects justified their relativistic judgments on informational grounds and their nonrelativistic judgments on moral grounds. These findings demonstrated that nonrelativistic and relativistic thinking coexist throughout a wide age range and underscored the need to distinguish between moral and nonmoral relativism when studying developmental patterns in the moral domain.  相似文献

Children employ multiple cues to identify the referent of a novel word. Novel words are often embedded in sentences and children have been shown to use syntactic cues to differentiate between types of words (adjective vs. nouns) and between types of nouns (count vs. mass nouns). In this study, we show that children learning Malay (N = 67), a numeral classifier language, can use syntactic cues to perform even finer-grained disambiguation–between count nouns. The manipulation of congruence between lexical and syntactic cues reveals a clear developmental trajectory: while 5-year-olds use predominantly lexical cues, older children increasingly rely on syntactic cues, such that by 7 years of age, they disambiguate between objects referred to with count nouns using syntactic rather than lexical cues.  相似文献

The main point of our study was to examine the vocabulary knowledge of pupils in grades 3–6, and in particular the relative reading vocabulary disadvantage of hearing-impaired pupils. The achievements of 394 pupils with normal hearing and 106 pupils with a hearing impairment were examined on two vocabulary assessment tasks: a lexical decision task and a use decision task. The target words in both tasks represent the vocabulary children should have at the end of primary school. The results showed that most hearing pupils reached this norm, whereas most hearing-impaired pupils did not. In addition, results showed that hearing-impaired pupils not only knew fewer words, but that they also knew them less well. This lack of deeper knowledge remained even when matching hearing and hearing-impaired children on minimal word knowledge. Additionally, comparison of the two tasks demonstrated the efficacy of the lexical decision task as a measure of lexical semantic knowledge.  相似文献

In two studies of knowledge about the properties and processes of memory for the times of past events, 178 children from 5 through 13 years of age and 40 adults answered questions about how they would remember times on different scales, how temporal memory is affected by retention interval, and the usefulness of different methods. The adults showed quite accurate knowledge about the main properties of memory for time and the processes that underlie it. Different properties and processes were first understood at ages ranging from 8 years to 12 years or later. Knowledge of the roles of reconstruction and impressions of temporal distances appear well after children use them to remember the times of events.  相似文献

The purpose of the present study was to investigate developmental differences in lexical processing and sensitivity to the positional information of constituent morphemes with reference to Chinese word-reading ability. One hundred mainland Chinese children (50 s graders and 50 third graders) and 22 high school students were tested with a lexical decision task. The primary school children were also tested for Chinese character reading, morphological awareness, phonological awareness, and non-verbal intelligence. We found that although both primary school children and high school students performed worse in the reversed condition (i.e., the pseudo-words were created by reversing the order of the two characters in real Chinese words) than in the real (i.e., real Chinese compound words) and random conditions (i.e., the pseudo-words were constructed by randomly combining the characters in the reversed condition), the performances of high school students in the reversed condition were closer to their performances in the other two conditions. Correlational analyses conducted on the primary school children revealed that the responses of second- and third-grade children on the lexical decision task were moderately correlated with their Chinese character reading. We also found that, after controlling for age and non-verbal IQ, the reaction time difference between the real and reversed conditions significantly predicted Chinese character reading. The results were discussed by exploring the nature of the lexical decision task, the sensitivity of Chinese children to the positional information of morphemes inside compound words, and the association of such sensitivity with their word-reading performance.  相似文献

Repetition priming was used to examine whether children with dyslexia bias a lexical–semantic pathway when reading words aloud. For the dyslexic group (n = 18, age 9.4–11.8 years), but not for age‐matched controls (n = 18, age 9.2–12.4 years), reaction times when naming pictures were faster after naming the corresponding word. A reading age‐matched control group (n = 24, age 6.8–8.9 years) showed similar priming effects to the children with dyslexia. The magnitude of repetition priming was greater for children with dyslexia with poor nonword reading and slower picture naming. Assuming repetition priming of picture naming is contingent on accessing lexical phonology via semantics, the results suggest less‐skilled normal and disordered readers show a stronger bias towards a lexical– semantic pathway during word reading than skilled readers, and the severity of the phonological representations deficit modulates the strength of that bias in children with dyslexia.  相似文献

A comparison was made between prelingually deaf and hearing children matched on reading age (between 7:0 and 7:11 years) in order to examine possible differences in reading performance. The deaf children all had a severe or profound hearing loss and were receiving special education in either a school or a unit for the deaf. The experimental tasks used a lexical decision task involving the reading of single words. The employment of phonology in reading was investigated by comparing reading performance on regular and irregular words and by comparing reading of homophonic versus non–homophonic nonwords. Both tasks revealed that hearing participants were much more affected by regularity and homophony, suggesting a much greater reliance on assembled phonological recoding. These results are discussed in terms of deaf readers relying on lexical access for reading print.  相似文献

Studies conducted in recent years on oral andwritten language production show that the ageat which words are learned is the main variablethat influences lexical access in both hearingpeople and people who have suffered brainlesions. No studies have been done with deafpeople and, since they use sign language inaddition to oral language, differencesregarding hearing people might be found intheir lexical organization. The aim of thisstudy was to test which variables determine thelexical production of deaf people. For thispurpose, 40 deaf people between the ages of 13and 58 years were asked to write individuallythe names of 100 pictures. The regressionanalyses performed on a total of 4000 responsesshow that the main predictor variable ofperformance was also age of acquisition. It isconcluded that the organization of the lexicalsystem in deaf people is similar to that of hearing people, although the phonologicalrepresentations of deaf people may be moreinaccurate.  相似文献

Concept of word—the awareness of how words differ from nonwords or other linguistic properties—is important to learning to read Chinese because words in Chinese texts are not separated by space, and most characters can be productively compounded with other characters to form new words. The current study examined the effects of reader, word, and character attributes on Chinese children’s concept of word in text. A total of 164 fifth-grade Chinese children participated in this study. Concept of word was measured by children’s lexical decisions about words and nonwords embedded in strings of characters. Cross-classified multilevel logistic models showed that reader attributes, including reading comprehension, vocabulary knowledge, and morphological awareness, interacted with certain word or character attributes in predicting children’s lexical decisions about words or nonwords. This study sheds light on the complex relationships between reader, word, and character attributes in the formation of concept of word in Chinese.  相似文献

The lexical restructuring model (LRM) is a theory that attempts to explain the developmental origins of phonological awareness (PA). According to the LRM, various characteristics of words should be related to the extent to which words are segmentally represented in the lexicon. Segmental representations of words allow children to access the parts of words needed to complete PA tasks. This study examined the relations between various lexical characteristics of Spanish and English words and the PA skills of Spanish-speaking language-minority children. Participants came from two independent samples of Spanish-speaking preschool children (Sample 1 N = 553, Sample 2 N = 600). For children in both samples, only phonotactic probability was related to children’s likelihood to respond correctly to Spanish PA items. Age of acquisition and word frequency were related to children’s likelihood to respond correctly to English PA items for children in both samples. Phonological neighborhood density and phonotactic probability were also related to children’s likelihood to respond correctly to English PA items; however, these effects were sample-specific. Children’s Spanish vocabulary knowledge moderated the effects of Spanish age of acquisition and word frequency on responses to Spanish PA items. Children’s English vocabulary knowledge moderated the effects of English phonological neighborhood density and phonotactic probability on responses to English PA items. These findings have implications for the development of PA assessments to be used with language-minority children.  相似文献
