We report an eye-movement study that demonstrates differences in regularity effects between adult developmental dyslexic and
control non-impaired readers, in contrast to findings from a large number of word recognition studies (see G. Brown, 1997). For low frequency words, controls showed an advantage for Regular items, in which grapheme-to-phoneme strategies could
be employed, compared with Irregular Consistent and Inconsistent items, in which rime comparisons or whole word recognition
strategies would be advantageous. We propose that in sentential contexts, dyslexic readers do not generate sufficient phonological
cues in the parafovea in order to demonstrate the regularity effects typical of unimpaired readers (e.g., S. Sereno & K. Rayner,
2000). These findings suggest that phonological strategies are sensitive to task demands, and underline the impact of methodology
on the conclusions that are drawn about dyslexic reading ability.

The phonological-core variable-orthographic differences (PCVOD) model [van der Leij, & Morfidi (2006). Journal of Learning Disabilities, 39, 74–90] has been proposed as an explanation for the heterogeneity among dyslexic readers in their profiles of reading-related
subskills. The predictions of this model were investigated in a sample of 72 Dutch secondary school students (dyslexics and
controls). First, the PCVOD assumption was confirmed that phonological processing and orthographic competence are independent
contributors to the prediction of reading fluency and spelling. Among the phonological processing tasks, phonological recoding
explained substantial unique variance, but not phonemic awareness or rapid serial naming. Next, the dyslexic readers were
divided into two subgroups based on high (ORTH+) and low levels (ORTH−) of orthographic competence. Both subgroups performed below controls on all measures tapping phonological processing, reading
and spelling but the ORTH+ group performed as well as non-disabled controls on Dutch and English orthographic choice. As predicted by the model, there
were no differences between the subgroups on the tasks that depend on phonological processing, with or without reading. There
were differences on Dutch word reading fluency and spelling. Furthermore, the ORTH+ subgroup outperformed ORTH− on tasks demanding speeded word processing such as ‘flashed’ presentation. This finding was independent of lexicality (words
or pseudowords), language (Dutch or English) or response mode (lexical decision or typing), but restricted to silent reading.
This supports the view that the ORTH+ subgroup is better at identifying larger orthographic units. There was no indication of differences between the subgroups
in reading experience. Our data, therefore, support the PCVOD model.

The study uses an orthographic judgment task to evaluate the efficiency of the lexical reading route in Italian dyslexic children.
It has been suggested that Italian dyslexic children rely prevalently on the sub-word-level routine for reading. However,
it is not easy to test the lexical reading route in Italian directly because of the lack of critical items (irregular words),
so visual lexical decision tasks and the comprehension/detection of pseudo-homophones are often used. While the former may
also be solved on the basis of visual familiarity or phonological re-codification, the latter also involves conceptual and
syntactic skills. Eleven dyslexic children participated in the study, performing an orthographic judgment task on stimuli
with two phonologically plausible spellings, of which only one was orthographically correct. Their performance was compared
with those of 11 proficient readers. The dyslexic children showed selective impairment in detecting phonologically plausible
errors, but their performance was normal when required to judge errors inserted in words with regular orthography, i.e., devoid
of orthographic ambiguity, and for which a sub-word-level reading procedure is sufficient to guarantee a good performance.
Overall, data are coherent with a diagnosis of surface dyslexia, with most children showing defective orthographic lexical
processing.

Despite an extensive literature linking individual differences in phonological processing to reading ability, some adults
show normal text comprehension abilities despite poor pseudoword reading (Jackson & Doellinger (2002). Journal of Educational Psychology, 94, 64–78). This study was undertaken to investigate differences between these individuals, termed resilient readers, and proficient
readers in performance and degree of lateralization on a variety of single word processing tasks. Participants completed seven
divided visual field tasks investigating various aspects of reading. Resilient readers performed less accurately on basic
word recognition tasks, but not on the tasks involving semantic access. Resilient readers did not differ from proficient readers
on reaction time or lateralization on any of the experimental tasks. These findings are consistent with the hypothesis that
skilled phonological decoding is not necessary for reading for meaning in a college population. It is proposed that higher-level
semantic information and general world knowledge may allow some readers to compensate for deficiencies in lower-level word
recognition processes.

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the
normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic
children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a
“surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition.
The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a
battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal
readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results
revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children
remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness
and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic
naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics.
A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception
word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over
one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit
Hypothesis. 相似文献

Our spelling training software recodes words into multisensory representations comprising visual and auditory codes. These
codes represent information about letters and syllables of a word. An enhanced version, developed for this study, contains
an additional phonological code and an improved word selection controller relying on a phoneme-based student model. We investigated
the spelling behavior of children by means of learning curves based on log-file data of the previous and the enhanced software
version. First, we compared the learning progress of children with dyslexia working either with the previous software (n = 28) or the adapted version (n = 37). Second, we investigated the spelling behavior of children with dyslexia (n = 37) and matched children without dyslexia (n = 25). To gain deeper insight into which factors are relevant for acquiring spelling skills, we analyzed the influence of
cognitive abilities, such as attention functions and verbal memory skills, on the learning behavior. All investigations of
the learning process are based on learning curve analyses of the collected log-file data. The results evidenced that those
children with dyslexia benefit significantly from the additional phonological cue and the corresponding phoneme-based student
model. Actually, children with dyslexia improve their spelling skills to the same extent as children without dyslexia and
were able to memorize phoneme to grapheme correspondence when given the correct support and adequate training. In addition,
children with low attention functions benefit from the structured learning environment. Generally, our data showed that memory
sources are supportive cognitive functions for acquiring spelling skills and for using the information cues of a multi-modal
learning environment. 相似文献

This study was intended to help clarify the nature of dyslexia in Spanish. A sample of 30 children, 8 to 16 years old, participated
in this study. Dyslexic children were compared to two control groups, a chronological age-matched control group and a reading
level-matched control group. Measures included nonword and pseudohomophone reading (phonological procedure), homophone choice
(orthographic procedure), and phonological awareness tasks (syllabic, intrasyllabic, and phonemic level). For each task, accuracy
(error percentage) and performance time were measured. Results showed a deficit in the dyslexic group on all the tasks, which
was more evident when time was considered. With the results consistent with studies in other transparent orthographies such
as Italian and German, speed problems seem to be more evident and relevant than accuracy problems in Spanish dyslexic children.

The authors analyzed self-reported SAT scores and actual SAT scores for five different samples of college students (N = 650). Students overestimated their actual SAT scores by an average of 25 points (SD = 81, d = 0.31), with 10% under-reporting, 51% reporting accurately, and 39% over-reporting, indicating a systematic bias towards
over-reporting. The amount of over-reporting was greater for lower-scoring than higher-scoring students, was greater for upper
division than lower division students, and was equivalent for men and women. There was a strong correlation between self-reported
and actual SAT scores (r = 0.82), indicating high validity of students’ memories of their scores. Results replicate previous findings (Kuncel, Credé,
& Thomas, 2005) and are consistent with a motivated distortion hypothesis. Caution is suggested in using self-reported SAT scores in psychological
research.

In the present study, conducted with French-speaking children, we examined the reliability (group study) and the prevalence
(multiple-case study) of dyslexics’ phonological deficits in reading and reading-related skills in comparison with Reading
Level (RL) controls. All dyslexics with no comorbidity problem schooled in a special institution for children with severe
reading deficits were included in the study (N = 15; Chronological Age [CA]: 111 ± 8 months; RL: 80 ± 3 months). For the group study, the 15 dyslexics were matched pairwise
on reading level, non-verbal IQ, and gender to 15 younger RL controls (CA: 85 ± 4 months). For the multiple-case study, the
RL control group included 86 average readers (CA: 83 ± 4 months; RL: 85 ± 5 months). To assess the relative efficiency of
the sublexical (or phonological) and lexical reading procedures, we relied on two comparisons: pseudowords vs. high-frequency
regular words (the comparison mainly used in languages with a shallow orthography); and pseudowords vs. high-frequency irregular
words (the comparison mainly used with English-speaking dyslexics), pseudowords and irregular words being either short or
long. The dyslexics’ skills in the domains supposed to explain their reading deficit were also examined: phonemic awareness,
phonological short-term memory and rapid naming. In the group study, the dyslexics lagged behind the RL controls only when
they were required to read long pseudowords. The results of the multiple-case study indicated that the prevalence of this
deficit was high (the accuracy scores of all but two of the 15 dyslexics being more than 1 SD below the RL control mean),
and that deficits in phonemic awareness were more prevalent (seven cases) than deficits in phonological memory (one case)
and in rapid naming (two cases). Three unexpected results were observed in the group study: the difference between regular
words and pseudowords (to the detriment of pseudowords) was not greater for the dyslexics; the difference between irregular
words and pseudowords (to the benefit of pseudowords) was more significant for the RL controls; and there were no significant
differences between the groups in reading-related skills. To explain these results, the severity of the dyslexics’ reading
deficit and the remediation they have benefited from must be taken into account. In addition, the fact that the outcomes of
the comparison between pseudoword vs. regular or irregular word reading were not the same will make it possible to understand
some discrepancies between studies carried out either in English or in a language with a shallower orthography (French, for
instance).

The lexical quality hypothesis assumes that skilled readers rely on high quality lexical representations that afford autonomous
lexical retrieval and reduce the need to rely on top-down context. This experiment investigated this hypothesis by comparing
the performance of adults classified on reading comprehension and spelling performance. ‘Lexical experts’, defined by above
average performance on both measures, were compared with individuals who are good readers/poor spellers, poor readers/good
spellers, or poor on both measures. Sentences finishing with a homograph (e.g., She danced all night at the ball) were followed by a probe word and participants had to decide whether it had occurred in the sentence. Critical probe words
were related to either the sentence-congruous or the sentence-incongruous meaning of the homograph (e.g., waltz vs. throw). Lexical experts showed less interference from related probes than the other groups. When the sentences were presented at
fast rates, poorer spellers showed interference for sentence-congruous but not sentence-incongruous probes. However, at slower
presentation rates, all groups showed equivalent interference for both types of probes. The results support the lexical quality
hypothesis by showing that high quality lexical representations, indexed by better spelling, are associated with reduced reliance
on sentence context.

Previous studies with English-speaking families in the North American context demonstrated that home literacy practices have
positive influences on children’s literacy acquisition. The present study expands previous studies by examining how home literacy
practices are related to growth trajectories of emergent literacy skills (i.e., vocabulary, letter-name knowledge, and phonological awareness) and conventional literacy
skills (i.e., word reading, pseudoword reading, and spelling), and by using data from Korean children and families (N = 192). The study revealed two dimensions of home literacy practices, home reading and parent teaching. Frequent reading
at home was positively associated with children’s emergent literacy skills as well as conventional literacy skills in Korean.
However, children whose parents reported more frequent teaching tended to have low scores in their phonological awareness,
vocabulary, word reading and pseudoword reading after accounting for home reading. These results suggest a bidirectional relationship
between home literacy practices, parent teaching in particular, and children’s literacy skills such that parents adjust their
teaching in response to their child’s literacy acquisition. Furthermore, cultural variation in views on parent teaching may
explain these results.

This paper reports the findings of an investigation aimed at gaining a clearer understanding of the nature of vocabulary difficulties
associated with dyslexia and associated risk status. Three studies were conducted to examine preschoolers’ access and mastery
of syntactic- and phonological-based processes believed to support word learning. Results are reported for 82 participants
whose (reading) risk status was assessed from a composite of measures known to be related to reading development. As expected,
risk status correlated positively with participants’ ability to recall the phonological form of novel nouns. No relationship
was found between risk status and participants’ use of syntactic form-class cues in interpreting the noun class of novel names
in isolation. However, the ability to use form-class cues was impaired for at-risk participants on a task that required them
to learn both the phonological form and noun class. Findings are discussed in relation to the suggestion that limitations
in processing resources such as working memory rather than in the availability of language structures may be at the root of
the reported poor performance by at-risk children on vocabulary and other linguistic measures.

Current models of self-regulated learning emphasize the pervasive need for metacognitive monitoring skills at all phases of
the learning process (Winne and Hadwin in Studying as self-regulated learning. In D. J. Hacker, J. Dunlosky, & A. C. Graesser
(Eds.), Metacognition in educational theory and practice (pp. 227–304). Mahwah, NJ: Erlbaum, 1998). In this investigation, we examined the impact of teaching 5th grade students how to self-monitor their comprehension and
make confidence judgments. One treatment class (N = 21) engaged in process-oriented comprehension monitoring training while the other (N = 24) engaged in both comprehension monitoring training and response-oriented monitoring accuracy training. Findings revealed
that students in both treatment classes improved their calibration accuracy and showed higher confidence on test performance
than students in two comparison classes (N = 47, N = 26) after 2 weeks of instruction. However, students in the monitoring accuracy training class also showed significant gains
in overconfidence in comparison to those in the other three classes. Implications for integrating comprehension-monitoring
training at the elementary school level are discussed.

This paper consists of three studies. The first study aimed to identify sub-types of students with learning disabilities in reading. Based on the dual-route model of reading, words may be read using either a lexical (words are recognized as wholes) or a sub-lexical (words are recognized through grapheme-phoneme correspondence) procedure. Castles and Coltheart (1993) provided evidence for the existence of these two mechanisms in English reading. They suggested that deficits in one and/or the other mechanism would lead to different patterns of reading disability. Surface dyslexia results from an impairment of the lexical procedure with an intact phonological route to reading. Phonological dyslexia results from a deficit in the grapheme-phoneme transformation mechanism. A higher percentage of surface dyslexia was identified in the present study. The aim of the second study was to analyze reading errors to support the existence of surface and phonological dyslexic patterns in Chinese reading. The results showed that students with surface dyslexic pattern made more phonological errors, whereas students with phonological dyslexic pattern made more semantic errors. These two studies indicate that students with learning disabilities could have different strengths and weaknesses and could have different preferences for recognizing Chinese characters and different responses to instructional methods. The third study was designed to test the effects of different teaching methods and different kinds of Chinese characters on students with learning disabilities. In general, the analytic method was found more effective for students with surface dyslexic pattern and the whole-word method for those with the phonological dyslexic pattern. The findings of this study showed the importance of identifying the strengths of the different sub-types of readers and the need to choose appropriate instructional methods accordingly. 相似文献

Outcomes of two training programs aimed at improving reading speed for 39 German-speaking poor readers in grades 2 and 4 were
evaluated. During a 6-week training period, a specific target for children in a computer group was to improve reading of word-initial consonant clusters by practice in associating an orthographic unit with a corresponding
phonological unit. Children in a paired reading group read books with an adult tutor. The results showed that, in reading words in which the computer-trained sublexical items
were included, both groups exhibited similar improvement. A post hoc analysis suggested that computer training was associated
with better reading skills with respect to the trained sublexical items; however, this improvement did not show large generalization
effects to the words with the sublexical items. The paired reading group showed a more rapid gain in global word reading fluency
than the computer group. Neither of the groups improved their pseudoword reading.

In this study we explore the development of phonological and lexical reading in dyslexic children. We tested a group of 14
Italian children who have been diagnosed with dyslexia and whose reading age is end of grade 1. We compared this group with
a group of 70 typically developing children who have been tested for reading at the end of grade 1. For each dyslexic child
we also selected a participant who was attending the same grade, was close in age, and showed typical reading development
when tested with a narrative passage reading task (Cornoldi, Colpo, & Gruppo MT, 1981) for correctness and reading speed. Children in this group are “same grade controls.” We used a reading task consisting of
40 three syllables words. A qualitative and quantitative method of coding children’s naming allowed us to distinguish several
components of their reading performance: the grapheme and word recognition, the size of orthographic units involved in the
aloud orthography–phonology conversion, the reading process used to recognize words. The comparison of the dyslexic group
with the reading age and the same grade control groups reveals different trends of delayed reading processes. Considering
dyslexic children’s chronological age, lexical reading is greatly delayed. Considering dyslexic children’s reading age, the
type of reading process that is more deeply delayed is phonological reading. The rate of fragmented phonological reading (i.e.,
a type of syllabized phonological reading) is much higher in dyslexic children compared to the reading age group, suggesting
that some factors undermine the possibility of internalizing the orthography–phonology conversion and the blending processes. 相似文献

Four experiments examined whether motor programming in handwriting production can be modulated by the syllable structure of
the word to be written. This study manipulated the number of syllables. The items, words and pseudo-words, had 2, 3 or 4 syllables.
French adults copied them three times. We measured the latencies between the visual presentation and the first production
(L1), the first and second production (L2), and the second and third production (L3). The results show an effect of the number
of syllables in L1 for pseudo-words but not for words and on L2 and L3 for all the items (Experiments 1 and 2). Experiment
3 ruled out an interpretation of the latencies for pseudo-words in terms of reading time with a delayed copying task. Experiment
4 replicated the previous results and assessed the effect of varying the temporal interval between the second and third trials.
The results of the four experiments confirm the role of the syllable in word writing. The number of syllables of a word modulates
the time course of handwriting production.

This study examined (1) the potential influence of oral language characteristics of two languages that bilingual children
acquire on their PA and (2) the relationship of PA in L1 with PA and literacy skills in L2, using data from Korean–English
bilingual children. Thirty three Korean–English bilingual children, composed of two subsamples from two different locations/bilingual
programs, participated in the study. The findings showed that the sample of bilingual children from two bilingual programs
differed in their mean performances on intrasyllabic phonological awareness in Korean (i.e., rime awareness and body awareness).
Furthermore, children’s Korean rime awareness, but not body awareness, was positively related to their phonological awareness
and literacy skills in English. Finally, these children’s phonological awareness in Korean made a positive contribution to
English decoding skills even after controlling for their English sight word reading skills. The results are discussed in light
of interlingual influence on bilingual children’s phonological awareness.
