First-grade children's reading, writing, and spelling competencies in 2 different instructional contexts for teaching phonics were examined. Reading, writing, and spelling abilities were measured at the beginning, middle, and end of 1st grade. Children were randomly assigned to 1 of 2 treatments designed to teach grapheme-phoneme correspondences, blending, and segmenting. In 1 treatment, children generated spellings for words, and in the other treatment, phonics instruction was embedded in literature. The spelling treatment was significantly better for spelling phonetically regular real and pseudowords, reading phonetically regular pseudowords, and written story length. It was also more beneficial for low-ability children's reading of connected text. There were no treatment effects on reading uncontrolled words in text. At the end of 5th grade, spelling-context children had significantly higher comprehension than did literature-context children. Discussion focuses on phonological processing while spelling and the effects of the instructional press of context-embedded and context-reduced instructional approaches in 1st grade.

Phonetic-cue reading involves reading words by storing and retrieving associations between some of the letters in spellings and sounds in pronunciations. Cipher reading involves processing all of the letter–sound relations in spellings. These two types of reading were compared experimentally. Novice beginning readers in kindergarten were assigned either to a group that was taught to decode—the cipher readers—or to a group that practiced isolated letter–sound relations—–the phonetic-cue readers. On posttests, cipher readers learned to read 15 similarly spelled words almost perfectly, whereas cue readers learned less than half of the words. Cipher readers also spelled better than cue readers. Errors indicated that cue readers were processing partial letter-sound cues in words. Results indicated that phonetic-cue reading is another way besides visual memory and decoding to read words. Results documented the importance of beginning readers' advancing beyond cue reading to cipher reading. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

The purpose of this study was to investigate the impact of speaking rate variations in the linguistic input provided to children during a novel word learning task. Thirty-two school-age children participated in this investigation, including 16 children with specific language impairment (SLI) and 16 normal language (NL) controls matched on mental age (MA). The younger half of the NL group also served as a vocabulary level comparison for the older half of the children with SLI. No significant rate effects were found for comprehension of novel words, with all children performing at relatively high levels of accuracy. The group with SLI demonstrated the same recognition accuracy pattern as MA matched controls for target labels versus phonetically similar/dissimilar foils only for words trained at slow rate. Rate effects were most pronounced for items with the highest difficulty level, namely production of novel words. Children with SLI produced significantly fewer words that had been presented at fast rate during training than NL children matched on mental age or vocabulary level. Individual differences and production error patterns on fast rate items were examined. The finding that variations in speaking rate had a disproportionate impact upon word learning for children with SLI was interpreted within a framework of limited processing capacity.  相似文献

An effective method for building meaning vocabulary in primary grades.   总被引:2,自引:0,他引:2  
Teaching vocabulary to primary grade children is essential. Previous studies of teaching vocabulary (word meanings) using story books in the primary grades reported gains of 20%-25% of word meanings taught. The present studies concern possible influences on word meaning acquisition during instruction (Study 1) and increasing the percentage and number of word meanings acquired (Study 2). Both studies were conducted in a working-class school with approximately 50% English-language learners. The regular classroom teachers worked with their whole classes in these studies. In Study 1, average gains of 12% of word meanings were obtained using repeated reading. Adding word explanations added a 10% gain for a total gain of 22%. Pretesting had no effect on gains. In Study 2, results showed learning of 41% of word meanings taught. At this rate of learning word meanings taught, it would be possible for children to learn 400 word meanings a year if 1,000 word meanings were taught. The feasibility of teaching vocabulary to primary grade children is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Researchers have attempted to understand the cognitive processing used in spelling by looking at children's spelling errors. The authors examined 2 other types of data—children's self-reported verbal protocols and on-line measures of spelling latencies. Elementary school children spelled 3 types of common 4-letter words, consonant–consonant–vowel–consonant, consonant–vowel–consonant–consonant, and consonant–vowel–consonant–silent e. Correctly and incorrectly spelled words were analyzed as a function of word type, verbal report, and keystroke latencies. Different typing patterns emerged for strategic and automatic reports and for different word types. Children seemed to use a relatively sequential read-out from long-term memory when directly retrieving a spelling, whereas they used a consonant pair strategy for final consonant clusters when sounding out words. Implications for spelling instruction are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Conducted 2 experiments, one with 12 6th graders considered to be good readers and one with 12 junior high and high school students who had normal IQs but were 2 yrs behind on standardized reading scores. Ss read passages of text which had been mutilated by changing the shape of the words and/or the initial, medial, or final letter of words. When the shape had been maintained by replacing letters with letters that shared distinctive features and were visually confusable with them, less reading time was taken and fewer errors were made than when the shape had been altered by replacing letters with letters that were not visually confusable with them. In addition, mutilations to the beginning of a word were considerably more disruptive than mutilations to the middle or end of a word. Good readers and poor readers showed highly similar data patterns. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

38 undergraduates learned to read words spelled with novel letters under phonics or whole-word conditions. Training was carried through several overlearning trials, and vocalization latency of word recognition responses was measured. On initial overlearning trials, vocalizations of phonics Ss were faster than those of whole-word Ss. At no stage of overlearning were whole-word Ss faster than phonics Ss. Vocalization latencies declined as overlearning progressed at approximately equal rates for phonics and whole-word Ss but did not reach fully automated speeds. Correlations of vocalization latencies from overlearning trials and a baseline task indicated that whole-word instruction resulted in word recognition mechanisms similar to fully automated mechanisms but that phonics instruction did not.

Participants' eye movements were recorded as they read sentences with words containing transposed adjacent letters. Transpositions were either external (e.g., problme, rpoblem) or internal (e.g., porblem, probelm) and at either the beginning (e.g., rpoblem, porblem) or end (e.g., problme, probelm) of words. The results showed disruption for words with transposed letters compared to the normal baseline condition, and the greatest disruption was observed for word-initial transpositions. In Experiment 1, transpositions within low frequency words led to longer reading times than when letters were transposed within high frequency words. Experiment 2 demonstrated that the position of word-initial letters is most critical even when parafoveal preview of words to the right of fixation is unavailable. The findings have important implications for the roles of different letter positions in word recognition and the effects of parafoveal preview on word recognition processes.

In 2 experiments, the authors examined whether spellings improve students' memory for pronunciations and meanings of new vocabulary words. Lower socioeconomic status minority 2nd graders (M = 7 years 7 months; n = 20) and 5th graders (M = 10 years 11 months; n = 32) were taught 2 sets of unfamiliar nouns and their meanings over several learning trials. The words were defined, depicted, and embedded in sentences. During study periods, students were shown written forms of 1 set but not the other set. Spellings were not present during word recall. Results of analyses of variance showed that spellings enhanced memory for pronunciations and meanings compared to no spellings (ps  相似文献

The mnemonic value of spellings in a paired-associate sound learning task was examined in 4 experiments. 120 1st and 2nd graders were taught 4 CVC nonsense sounds as oral responses. The stimuli were geometric figures or numbers of alphabet letters corresponding to initial consonant sounds. Various types of adjunct aids or activities occurred during study and feedback periods as the learning trials progressed. Visual spellings or misspellings of the CVC sounds were shown, or Ss imagined visual spellings, or they listened to oral spellings or to sounds broken into phonetic segments, or they rehearsed the sounds. Spellings were not present during test trials when sounds were recalled. In all experiments, sound learning was fastest when correct spellings were seen or imagined. The preferred interpretation is that spellings are effective because they provide readers with orthographic images useful for symbolizing and storing sounds in memory. Spelling-aided sound learning scores were highly correlated with Ss' knowledge of printed words, indicating that this representational process may be used by beginning readers to store printed words in lexical memory.

Subsyllabic awareness was investigated with a word synthesis task. Children from kindergarten, 1st grade, and 2nd grade attempted to blend auditorily presented CCVC word segments (where C?=?consonant and V?=?vowel) to produce words. Subsyllabic segmentation and presentation rate of the word segments were varied, and the dependent measure was percentage correct in each condition. Several posttests were administered to measure the children's preexisting ability to recognize visually presented consonants, consonant clusters, rimes, and words. Second graders performed better than 1st graders, who in turn performed better than kindergarteners. Performance of all children was best on words that were segmented between onset and rime and poorest for words that were segmented into individual phonemes. Performance for word segrnents that were presented at the fast rate was better than for those presented at the slow rate. The authors suggest that preliterate children are able to manipulate suprasegmental units such as onset and rime, and that those units should be emphasized in early reading instruction.

In this study, 1.5-year-olds were taught a novel word. Some children were familiarized with the word's phonological form before learning the word's meaning. Fidelity of phonological encoding was tested in a picture-fixation task using correctly pronounced and mispronounced stimuli. Only children with additional exposure in familiarization showed reduced recognition performance given slight mispronunciations relative to correct pronunciations; children with fewer exposures did not. Mathematical modeling of vocabulary exposure indicated that children may hear thousands of words frequently enough for accurate encoding. The results provide evidence compatible with partial failure of phonological encoding at 19 months of age, demonstrate that this limitation in learning does not always hinder word recognition, and show the value of infants' word-form encoding in early lexical development.

The authors investigated whether the meaning of visually presented words is activated faster for early-acquired words than for late-acquired words. They addressed the issue using the semantic Simon paradigm. In this paradigm, participants are instructed to decide whether a stimulus word is printed in uppercase or lowercase letters. However, they have to respond with a verbal label ("living" or "nonliving") that is either congruent with the meaning of the word (e.g., saying "living" to the stimulus DOG) or incongruent (e.g., saying "nonliving" to the stimulus dog). Results showed a significant congruency effect that was stronger for early-acquired words than for late-acquired words. The authors conclude that the age of acquisition is an important variable in the activation of the meaning of visually presented words.

Two experiments were conducted to examine the importance of inhibitory abilities and semantic context to spoken word recognition in older and young adults. In Experiment 1, identification scores were obtained in 3 contexts: single words, low-predictability sentences, and high-predictability sentences. Additionally, identification performance was examined as a function of neighborhood density (number of items phonetically similar to a target word). Older adults had greater difficulty than young adults recognizing words with many neighbors (hard words). However, older adults also exhibited greater benefits as a result of adding contextual information. Individual differences in inhibitory abilities contributed significantly to recognition performance for lexically hard words but not for lexically easy words. The roles of inhibitory abilities and linguistic knowledge in explaining age-related impairments in spoken word recognition are discussed.

Eye movements were monitored as subjects read sentences containing high- or low-predictable target words. The extent to which target words were predictable from prior context was varied: Half of the target words were predictable, and the other half were unpredictable. In addition, the length of the target word varied: The target words were short (4–6 letters), medium (7–9 letters), or long (10–12 letters). Length and predictability both yielded strong effects on the probability of skipping the target words and on the amount of time readers fixated the target words (when they were not skipped). However, there was no interaction in any of the measures examined for either skipping or fixation time. The results demonstrate that word predictability (due to contextual constraint) and word length have strong and independent influences on word skipping and fixation durations. Furthermore, because the long words extended beyond the word identification span, the data indicate that skipping can occur on the basis of partial information in relation to word identity.

In the present study, we investigated critical factors in letter-sound acquisition (i.e., letter-name knowledge and phonological awareness) with data from 653 English-speaking kindergartners in the beginning of the year. We examined (a) the contribution of phonological awareness to facilitating letter-sound acquisition from letter names and (b) the probabilities of letter-sound acquisition as a function of letter characteristics (i.e., consonant–vowel letters, vowel–consonant letters, letters with no sound cues, and vowel letters). The results show that letter-name knowledge had a large impact on letter-sound acquisition. Phonological awareness had a larger effect on letter-sound knowledge when letter names were known than when letter names were unknown. Furthermore, students were more likely to know the sounds of consonant–vowel letters (e.g., b and d) than vowel–consonant letters (e.g., l and m) and letters with no sound cues (e.g., h and y) when the letter name was known and phonological awareness was accounted for. Sounds were least likely to be known for letters with no sound cues, but reliable differences from other groups of letters depended on students' levels of phonological awareness and letter-name knowledge.

To examine the relationship between knowledge of word meanings and semantic processes, 27 4th-grade children were taught 104 words over a 5-mo period. Following instruction, Ss performed tasks designed to require semantic processes ranging from single word semantic decisions to simple sentence verification and memory for connected text. On all these tasks, instructed Ss performed at a significantly higher level than controls matched on pre-instruction vocabulary knowledge and comprehension. Thus, instructed Ss gave evidence both of learning word meanings taught by the program and of being able to process instructed words more efficiently in tasks more reflective of comprehension. Implications for vocabulary instruction and the role of individual word meanings in comprehension are discussed. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Studied how 2 components of phonemic awareness, recognition of phoneme identity across words and recognition of phonemic segmentation within words, influence acquisition of the alphabetic principle in preliterate children. Evidence favored training in phoneme identity over segmentation as a component of initial reading instruction because it was easier to implement and its relationship to alphabetic insight was stronger. The study also found that identity can be equally easily taught using word-initial and word-final phonemes, a phoneme in a consonant cluster does not present special problems, vowels are as amenable to training as consonants, and stops are more problematic than continuants. Once alphabetic insight is established for some letters, following identity and letter–sound instruction, it generalizes to other letters without the need for further phonemic awareness training. Implications for the initial reading curriculum are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Many models of spoken word recognition posit the existence of lexical and sublexical representations, with excitatory and inhibitory mechanisms used to affect the activation levels of such representations. Bottom-up evidence provides excitatory input, and inhibition from phonetically similar representations leads to lexical competition. In such a system, long words should produce stronger lexical activation than short words, for 2 reasons: Long words provide more bottom-up evidence than short words, and short words are subject to greater inhibition due to the existence of more similar words. Four experiments provide evidence for this view. In addition, reaction-time-based partitioning of the data shows that long words generate greater activation that is available both earlier and for a longer time than is the case for short words. As a result, lexical influences on phoneme identification are extremely robust for long words but are quite fragile and condition-dependent for short words. Models of word recognition must consider words of all lengths to capture the true dynamics of lexical activation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Three experiments were conducted within the framework of the Neighborhood Activation Model of spoken-word recognition to study how the structural organization of the mental lexicon may contribute to age-related declines in spoken-language processing. Experiment 1 showed that the number and frequency of words that are phonetically similar to a target word had differential effects on perceptual identification in older and younger adults, with older adults being particularly disadvantaged in identifying hard words (words phonetically similar to many other high-frequency words). Experiment 2 showed that age-related deficits in the ability to identify hard words remained under conditions in which performance for a set of easy words (items phonetically similar to relatively few other low-frequency words) was the same for older and younger adults. In Experiment 3, reducing the resources available for identification by changing from single to multiple talkers reduced word recognition more among older than younger adults. Diminished cognitive resources, impaired inhibitory control, and increased general slowing are discussed as explanations for the results.
