We report two training studies designed to investigate the relation between phonological awareness, sound‐to‐letter mapping knowledge, and printed word learning in novice five‐year‐old readers. Effects of visual memory and of teaching methods are also explored. In our first study, novice five‐year‐old readers able to segment initial phonemes and with good knowledge of mappings between sounds and letters learned words more easily from repeated exposure to texts. Results suggested that visual memory influenced word learning in non‐segmenting but not in segmenting children. Spelling regularity did not affect ease of learning. Nouns were easier to learn than function words. In the second study, although phonological awareness and sound‐to‐letter mapping knowledge still exerted a significant influence, all novice five‐year‐olds were able to learn words more easily if these were taught out‐of‐context singly on flashcards. Results support the view that mental representations of printed words are more easily formed by beginners who are able to match at least some of the phonological segments detected in the spoken word to letters in the printed word. 相似文献

A sample of 131 10–14‐year‐old Dutch children with reading and spelling difficulties received a treatment for dyslexia. The treatment was computer‐based and focused on learning to recognise and use the phonological and morphological structure of Dutch words. The treatment consisted of several modules, each addressing specific links between phonological concepts and the writing system. A process‐oriented evaluation of this treatment showed a time course of effects that was specifically related to the timing of treatment components. The children showed a cascade of improvements that corresponded to the presentation order of the treatment modules. These findings indicate that the computerised treatment based on inferential algorithms provides an effective tool in the remediation of dyslexia. 相似文献

This article reports two experiments in which the artificial orthography paradigm was used to investigate the mechanisms underlying learning to read. In each experiment, participants were taught the meanings and pronunications of words written in an unfamiliar orthography, and the statistical structure of the mapping between written and spoken forms (O-P) was manipulated independently of the mapping between written forms and their meanings (O-S). Our results support three main conclusions. First, the statistical structure of O-P and O-S mappings determined how easily each of those mappings was learned, suggesting that the learning of both mappings engages a common statistical learning mechanism. Second, learning to read is a cooperative process, in that learning in any particular component of the reading system is influenced by knowledge stored in the rest of the system. Finally, knowledge of sublexical regularities can be acquired as the result of exposure to words embodying those regularities. 相似文献

Three experiments investigated the effects of rime consistency on reading and spelling among developing readers ranging in
age from 7 to 11 years. Experiment 1 found that children read words with inconsistent feedforward mappings between orthography
and phonology (O → P) less accurately than consistent words. OP consistency interacted with chronological age, word frequency
and age-of-acquisition (AoA). The effect of OP consistency on reading was larger for younger children than for older children
and OP consistency had an effect for low frequency words and late-acquired words only. Experiment 2 found an effect of feedforward
consistency between phonology and orthography (P → O) on children’s spelling but no interaction between PO consistency and
AoA. Experiment 3 showed that the effects of feedforward consistency are independent of feedback consistency. Our results
challenge models of reading and spelling that assume feedforward consistency effects are influenced by the frequency of exposure
to words only and we suggest that interactions between consistency and AoA depends on the ratio of consistent to inconsistent
OP mappings. 相似文献

Abstract Seven primary school children with behaviour difficulties showed low levels of on‐task writing behaviour, high levels of off‐task disruptive behaviour and a low number of words written during regular classroom story writing sessions. Introduction of self‐recording of work behaviours during story writing for the whole class of 34 children was associated with increased on‐task, decreased off‐task disruptive behaviour and an increased number of words written for target children. There was also an increased number of words written by six other children for whom story writing data was collected. Introduction of say‐do correspondence training for five of the target children showed further increases in independent story writing behaviour and reductions in off‐task behaviours that disrupted the written language sessions. 相似文献

Visual information influences speech perception in both infants and adults. It is still unknown whether lexical representations are multisensory. To address this question, we exposed 18‐month‐old infants (n = 32) and adults (n = 32) to new word–object pairings: Participants either heard the acoustic form of the words or saw the talking face in silence. They were then tested on recognition in the same or the other modality. Both 18‐month‐old infants and adults learned the lexical mappings when the words were presented auditorily and recognized the mapping at test when the word was presented in either modality, but only adults learned new words in a visual‐only presentation. These results suggest developmental changes in the sensory format of lexical representations. 相似文献

This study examined how colored educational tools improve children’s numerosity (“number sense”) and/or mathematics. We tested children 6–10 years (n = 3,236) who had been exposed to colored numbers from the educational tools Numicon (Oxford University Press, 2018) or Numberjacks (Ellis, 2006), which map colors to magnitudes or Arabic numerals, respectively. In a free association task pairing numbers with colors, a subset of children spontaneously provided colors matching one of these schemas. These children, who had internalized Numicon (colored magnitude), showed significantly better numerosity but not mathematics compared to peers. There was no similar benefit from internalizing Numberjacks (colored numerals). These data support a model in which colored number tools provide benefits at different levels of numerical cognition, according to their different levels of cross-modal mappings. 相似文献

Trait Understanding or Evaluative Reasoning? An Analysis of Children''s Behavioral Predictions 总被引：3，自引：0，他引：3
This study tested the hypothesis that in predicting the future behavior of an actor, older children rely on trait inferences, whereas younger children rely on global, evaluative inferences. Vignettes depicting actors engaging in trait-relevant behaviors were presented to 5- and 6-year-olds (N = 67) and 9- and 10-year-olds (N = 71). For each actor, children made predictions of future behavior, evaluated the goodness and badness of the actor, and rated each actor on a relevant trait. A mediational analysis found that the behavioral predictions of older children were mediated solely by trait ratings, whereas those of younger children were mediated by evaluative ratings. Furthermore, unlike older children, younger children made trait-like predictions only when they made an evaluation of the actor. These results suggest that young children utilize evaluative reasoning when making behavioral predictions, and therefore rely on an inferential process that is distinct from that of older children. 相似文献

Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. The current study hypothesizes that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. In this study of 71 ninth graders, it is shown that students with MLD have significantly poorer ANS precision than students in all other mathematics achievement groups (low, typically, and high achieving), as measured by psychophysical assessments of ANS acuity (w) and of the mappings between ANS representations and number words (cv). This relation persists even when controlling for domain-general abilities. Furthermore, this ANS precision does not differentiate low-achieving from typically achieving students, suggesting an ANS deficit that is specific to MLD. 相似文献

Competence in early mathematics is crucial for later school success. Although research indicates that early mathematics curricula improve children's mathematics skill, such curricula's impacts on oral language and early literacy skills are not known. This project is the first to investigate the effects of an intensive pre-kindergarten mathematics curriculum, Building Blocks, on the oral language and letter recognition of children participating in a large-scale cluster randomized trial project. Results showed no evidence that children who were taught mathematics using the curriculum performed differently than control children who received the typical district mathematics instruction on measures of letter recognition, and on two of the oral language (story retell) subtests, sentence length and inferential reasoning (emotive content). However, children in the Building Blocks group outperformed children in the control group on four oral language subtests: ability to recall key words, use of complex utterances, willingness to reproduce narratives independently, and inferential reasoning (practical content). 相似文献

Reading relies on a left‐lateralized network of brain areas that include the pre‐lexical processing regions of the ventral stream. Specifically, a region in the left lateral occipitotemporal sulcus (OTS) is consistently more activated for visual presentations of words than for other categories of stimuli. This region undergoes dramatic changes at the functional and structural levels when children learn to read, but little is known about the effects of early cerebral constraints on reading skills. Using anatomical magnetic resonance imaging, we investigated whether the sulcal pattern of the lateral OTS—a stable brain feature—was associated with oral reading skills. The sulcal pattern of the left but not the right lateral OTS was associated with the number of words correctly read in 3 min. This study is the first to evidence that reading is affected by early cerebral constraints, such as the sulcal morphology of the left lateral OTS. 相似文献

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N = 50) found that 5‐ to 6‐year‐olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This bias occurred despite children acknowledging the expert model's superior capability. Experiment 2 (N = 50) demonstrated a shift in 7‐ to 8‐year‐olds toward copying the expert. Children aged 9–10 years did not copy according to a model bias. The findings of a follow‐up study (N = 30) confirmed that, instead, they prioritized their own—partially flawed—causal understanding of the puzzle box. 相似文献

Early in development, many word‐learning phenomena generalize to symbolic gestures. The current study explored whether children avoid lexical overlap in the gestural modality, as they do in the verbal modality, within the context of ambiguous reference. Eighteen‐month‐olds’ interpretations of words and symbolic gestures in a symbol‐disambiguation task (Experiment 1) and a symbol‐learning task (Experiment 2) were investigated. In Experiment 1 (N = 32), children avoided verbal lexical overlap, mapping novel words to unnamed objects; children failed to display this pattern with symbolic gestures. In Experiment 2 (N = 32), 18‐month‐olds mapped both novel words and novel symbolic gestures onto their referents. Implications of these findings for the specialized nature of word learning and the development of lexical overlap avoidance are discussed. 相似文献

Some previous studies of visual word recognition have reported an interaction between visual field and word length (measured by number of letters), such that recognition is affected more by word length for words presented in the left than for words presented in the right visual field. However, when manipulating serial position of letters in words to measure length effects, there are also reports of symmetrical word length effects in the two visual fields. Here we report two experiments, presenting four‐ and seven‐letter words, suggesting that the serial position and length effects in the hemispheres are separable and task dependent. For tasks that rely more heavily on letter‐level processing such as letter search (Experiment 1), performance in both hemifields showed similar effects of serial position; however, when comparing four‐ and seven‐letter words, an effect of word length was evident only in the left visual field, in line with the well‐established interaction between word length and hemifield. An interaction between word length and hemifield was confirmed for the same stimuli when they were employed in a lexical decision task, which forced whole‐word processing (Experiment 2). We conclude that the effects of serial position and number of letters in the two visual fields are separable, and are selectively affected by task type. 相似文献

The research question here was whether whole‐word shape cues might facilitate reading in dyslexia following reports of how normal‐reading children benefit from using this cue when learning to read. We predicted that adults with dyslexia would tend to rely more on orthographic rather than other cues when reading, and therefore would be more affected by word shape manipulations. This prediction was tested in a lexical decision task on words with a flat or a non‐flat outline (i.e. without or with letters with ascending/descending features). We found that readers with dyslexia were significantly faster when reading non‐flat compared with flat words, while typical readers did not benefit from whole‐word shape cues. The interaction of participants' group and word shape was not modulated by word frequency; that is word outline shape facilitated reading for both rare and frequent words. Our results suggest that enhanced sensitivity to orthographic cues is developed in some cases of dyslexia when normal, phonology‐based word recognition processing is not exploited. 相似文献

We report a training study that assesses whether teaching the pronunciation and meaning of spoken words improves Chinese children’s subsequent attempts to learn to read the words. Teaching the pronunciations of words helps children to learn to read those same words, and teaching the pronunciations and meanings improves learning still further. These results provide evidence that both phonological and semantic knowledge are causal influences on learning to read words aloud in Chinese. It appears that learning to read words in Chinese may entail a greater reliance on mappings from orthography to semantics than learning to read words in alphabetic orthographies. 相似文献

Children who read poorly have difficulty naming objects, and their errors usually bear a semantic or a phonetic resemblance
to the correct words. Excessive semantic and phonetic naming errors could both be due to underlying phonological deficiencies
in poor readers. When children cannot name an object because its name is not represented well in long-term memory or cannot
be processed well, semantic information as well as partially available phonological information may be used in selecting an
alternative response. This hypothesis was tested by looking for the joint influence of semantics and phonology in the naming
errors of third-grade children. The same children were asked to name a set of pictured objects, repeat the object names after
being spoken by the examiner, and recognize the objects from their spoken names. A separate group of children produced associative
responses to the same pictures. First, it was found that, compared with skilled readers, less-skilled readers who named objects
without any time pressure had a deficit that could not be attributed to repetition difficulty or limited vocabulary. Second,
the naming errors showed a semantic relationship to the correct words that was as strong as that of the associative responses.
Third, the naming errors also showed a phonetic relationship to the correct words, whereas the associative responses did not.
Finding a joint semantic and phonetic effect in the naming errors of children suggests that the errors may be attributable
to phonological deficiencies. 相似文献

A significant gap in emerging literacy intervention with preschoolers relates to a skill that is crucial to later reading comprehension–the ability to engage in inferencing. This article presents a theoretical rationale for fostering inferential language during book sharing with preschool children, and provides research‐based ideas for how this can be best accomplished. It is suggested that, at the preschool level, children can be supported in their ability to make inferences about stories read aloud to them by having adults ask both literal and inferential questions that, first and foremost, relate to the causal structure of stories. Additionally, questions focused on informational and evaluative inferences serve to further enhance story comprehension. A rubric for connecting such questions to the elements of story grammar is offered, and a specific example from a published preschool level storybook is provided. © 2008 Wiley Periodicals, Inc. 相似文献
