Motor skills, automaticity and developmental dyslexia: A review of the research literature

This paper reviews a body of prominent theoriesof automaticity in developmental dyslexia. Thefirst part of the review considers therelationship between dyslexia and rapidautomatic naming and fluency. Additionaltheoretical and empirical advances aresuggested to this already strong research base.In particular, there is a need is forexperimental work elucidating the nature ofnaming speed deficits and providing independentevidence of the automaticity of rapid naming.The second part of the review considersevidence for deficits in motor automaticity indyslexic children. Here, a more mixed patternof results is evident. It is concluded thatthere is currently clearer evidence forlanguage-based than motor-based automaticitydeficits. Future motor automaticity research islikely to require the routine screening of poorreaders for common co-occurring developmentaldifficulties, improved sampling and prospectivelongitudinal studies.     

Differential relationships between RAN performance,behaviour ratings,and executive function measures: Searching for a double dissociation

Abstract. In this study, we investigated the relationships between rapid naming of letters, digits and colours, and reading ability and executive function. We gave fifty-six grade three and four children rapid automatised naming tasks using letters and digits as stimuli, executive function measures including the Stroop task, a working memory task and the Trailmaking B task. The latter three tasks were used as measures of executive function. We also administered tests of verbal ability, reading and a behaviour checklist. The rapid naming of letters and digits was significantly correlated with reading, but not with executive function or behaviour ratings. The rapid naming of colours (from the Stroop task) was significantly correlated with the executive function tasks and the behaviour ratings but not with reading. We discuss the implications of this double dissociation for further studies of RAN.     

Rapid naming speed and reading across languages that vary in orthographic consistency

The objective of this study was to examine how rapid naming speed is related to reading ability across languages that vary in orthographic consistency. Forty English-speaking Canadian children, 40 Greek-speaking Cypriot children, and 40 Chinese-speaking Taiwanese children were administered RAN, reading accuracy, and reading fluency tasks in grade 4. The results revealed that across languages there were no statistically significant differences in the correlations between RAN and reading. However, a subsequent analysis of the RAN components—articulation and pause time—revealed that different RAN components may be responsible for the RAN-reading relationship across languages. Implications for existing theories relating RAN to reading are discussed.     

Rapid naming speed and Chinese character recognition

We examined the relationship between rapid naming speed (RAN) and Chinese character recognition accuracy and fluency. Sixty-three grade 2 and 54 grade 4 Taiwanese children were administered four RAN tasks (colors, digits, Zhu-Yin-Fu-Hao, characters), and two character recognition tasks. RAN tasks accounted for more reading variance in grade 4 than in grade 2, and graphological RAN tasks accounted for more reading variance than RAN Colors. After controlling for age, nonverbal intelligence, phonological sensitivity, short-term memory, and orthographic processing, RAN tasks were significant predictors of character recognition fluency in grade 2, and of both accuracy and fluency in grade 4.

荀子的制名原则和制名方法思想包括“同则同之,异则异之”原则;单名和兼名、“共名”、“别名”、“大共名”与“大别名”的分类方法;“遍举”之“共名”与“偏举”之“别名”明确名的逻辑方法;约定俗成的制名原则和“稽实定数”的制名原则。此思想包含有丰富的逻辑理论。但荀子继承了孔予的正名传统,其制名原则和制名方法等思想主要是为当时的社会政治、伦理秩序和儒家思想服务的。     

Theoretical links among naming speed,precise timing mechanisms and orthographic skill in dyslexia

In this paper, we review several lines of convergent research to discuss the relationship between developmental dyslexia and slow symbol naming speed. We describe the interactive development of orthographic and phonological codes, and we discuss the methodological problems that may have led to underestimating the importance of individual differences in orthographic processing in our account of reading disabilities. Symbol naming speed is typically subsumed under phonological processing, yet it contributes variance to reading, especially to reading fluency, independently of phonological awareness. We speculate that naming speed may reflect precise timing mechanisms necessary to the development of orthographic codes and to their integration with phonological codes. We argue that an understanding of this precise timing dimension is necessary to incorporate in our models of phonological, orthographic, and semantic processes in reading acquisition and reading failure.     

Comparing the phonological and double deficit hypotheses for developmental dyslexia

This study tested the predictions of thephonological and double deficit hypotheses byexperimentally examining speech perception,phoneme awareness, lexical retrieval (serialand discrete), articulatory speed, and verbalSTM in school age child (N = 35) and adolescent(N = 36) dyslexics, and both chronological age(CA) and reading age (RA) controls. Theresults confirmed the findings of previousstudies of a deficit in phoneme awareness indevelopmental dyslexia. At both age levels,dyslexics performed significantly more poorlythan both their CA and RA controls. Althoughdeficits in the other processes investigated,particularly in rapid serial naming, were alsoapparent, they were not as clear-cut as thedeficit in phoneme awareness. In general,definite evidence of a deficit in rapid serialnaming was limited to the more severelyimpaired dyslexics. Furthermore, although rapidserial naming contributed independent variationto various literacy skills, its contributionwas modest relative to the contribution ofphoneme awareness, regardless of whether theliteracy skill relied more or less heavily onphonological or orthographic coding skills. Further analyses suggested that variation inrapid serial skill is particularly importantfor fluent reading of text, whereas phonemeawareness is particularly important for thedevelopment of the ability to read byphonologically recoding letters or groups ofletters in words into their phonological codes.This explains the relatively strongcontribution of phoneme awareness to readingand spelling ability in general. In sum, thephonological hypothesis offers a moreparsimonious account of the present resultsthan the double deficit hypothesis.

Cognitive profiling in Chinese developmental dyslexia with attention-deficit/hyperactivity disorders

The cognitive profiles of children with Developmental Reading Disorder (RD) and Attention-Deficit/Hyperactivity Disorders (ADHD) have been extensively studied in alphabetic language communities. Deficits in phonological processing and rapid naming have been implicated as core features of RD although whether the latter is a deficit specific to RD remains controversial. Similar research aiming to explore the cognitive profiles of children with both RD and ADHD in non-alphabetic language communities is limited. The specificity of rapid naming deficit to RD among Chinese has yet to be studied. In the first study, 43 Chinese children with confirmed diagnoses of RD + ADHD were assessed on their cognitive abilities in relating to reading. In the second study, the specificity deficit hypothesis of rapid naming to RD but not ADHD was examined. A digit naming test was administered to the RD + ADHD group (43 subjects) and an ADHD only group (49 subjects). In regard to cognitive profiling, rapid naming and orthographic knowledge were found to be the most common deficits among the Chinese RD + ADHD group. This co-morbid group was also found to have a significant deficit performance on the rapid naming task than the ADHD only group. The present findings support the double dissociation hypothesis in cognitive deficit between RD and ADHD. The results of both studies are discussed with reference to the findings of the Western counterparts.     

Derivational morphology and spelling in dyslexia

This exploratory study aimed to evaluate the spelling of derived words by dyslexic adolescents and to verify whether this is associated with lack of vocabulary and/or morphological knowledge. A cross-sectional reading level-design was employed in order to determine differences in spelling, derivational morphology and vocabulary tasks between dyslexic students aged 13+ and age-matched and reading level matched control groups. The study confirmed a profound spelling impairment of dyslexic students in comparison with two control groups but this was not associated with poor vocabulary in relation with their age-peers. In contrast, they exhibited lower levels of morphological knowledge than age-matched controls but equivalent with the reading level controls. These results are interpreted in the light of current developmental models of spelling that support a reciprocal interaction between spelling and metamorphology.     

Letter Processing and the Formation of Memory Representations in Children with Naming Speed Deficits

The ability to recognize letter patterns within words as a single unit is important for fluent reading. This skill is based on previously established memory representations of common letter patterns. The ability to form these memory representations may be impaired in some poor readers, particularly readers with naming speed deficits (NSD). This study explored factors that influence letter processing and the subsequent formation of memory representations of letter strings in children with and without a NSD. Children were presented with a letter string, followed by a probe unit that was either a single letter, a two-letter cluster, or a repetition of the whole string. Children indicated whether or not the probe had been present in the preceding string. Two factors were manipulated: (a) amount of time to process the initial letter string, and (b) level of orthographic structure present in the letter string. Results indicated that overall, children with NSD performed less accurately than children without NSD. However, children with NSD showed no differential benefit in performance as a result of longer time to process a letter string. In addition, all readers were able to make use of the orthographic structure in a letter string to aid performance. Implications of results for establishing memory representations of letter strings are discussed.     

Academic motivation in children with dyslexia

The authors' purpose was to determine which form of therapeutic aid may influence academic approach and avoidance motivation in children with dyslexia. There were 165 children with dyslexia assessed with the use of ”I and my school” questionnaire. The authors considered the children's previous therapeutic experience and on its basis they were divided into three groups. Children receiving systematic therapeutic treatment display a significantly higher level of academic approach motivation as compared to those from the two other groups. Those children also manifest a lower level of academic avoidance motivation compared to those receiving no form of specialist treatment. Girls, regardless of their therapeutic experience, demonstrate a higher level of approach motivation; boys, on the other hand, display a higher level of avoidance motivation. The study shows that the quality of provided therapeutic aid affects emotional-motivational sphere of children with dyslexia. Systematic therapeutic aid increases academic approach motivation and reduces avoidance motivation.     

Observations on the temporal correlates of reading failure

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.

Immune disorders and dyslexia

The Geschwind-Behan-Galaburda hypothesis of cerebral lateralization postulates an association between immune disorders and learning disabilities. So far, the empirical evidence for such a relationship has been ambiguous. The present study is an attempt to investigate the hypothesis in a population where all the individuals were affected by immune disorders. Thus, 29 students in a special school for asthmatic children (total number of students in the school: 32) were investigated. A number of reading tests with special focus on word decoding were administered. The parents filled in a detailed questionnaire on the prevalence of reading difficulties and immune disorders among the other family members. The proportion of students with reading problems — especially phonological problems — was much higher than would be expected in a normal population. Among the family members we also found an elevated incidence of both reading problems and immune disorders. A cautious interpreptation of these findings leads to tentative and partial support of the Geschwind-Behan-Galaburda hypothesis.     

Persistence of phonological awareness deficits in older children with dyslexia

Three groups of children with dyslexia, with mean age 8, 13 and 17 years, together with three groups of normally achieving children matched for age and IQ with the dyslexic groups, undertook tests of sound categorization and phoneme deletion. The design allowed comparison not only across chronological age but also across reading age. The children with dyslexia performed significantly worse even than their reading age controls on both tasks. Indeed, overall performance of the 17 year old children with dyslexia was closest, but inferior, to that of the 8 year old controls. Since the sound categorization task was designed to minimize working memory load, the results extend previous findings on the phonological awareness deficits in dyslexia by dissociating the deficit from memory load and by showing that it persists at least into late adolescence.

Mixture growth models of RAN and RAS row by row: insight into the reading system at work over time

Children (n = 122) and adults (n = 200) with dyslexia completed rapid automatic naming (RAN) letters, rapid automatic switching (RAS) letters and numbers, executive function (inhibition, verbal fluency), and phonological working memory tasks. Typically developing 3rd (n = 117) and 5th (n = 103) graders completed the RAS task. Instead of analyzing RAN/RAS results the usual way (total time), growth mixture modeling assessed trajectories of successive times for naming 10 symbols in each of five rows. For all three samples and both RAN and RAS, two latent classes were identified. The “faster” class performed slowly on the first row and increased time by small increments on subsequent rows. The “slower” latent class performed more slowly on the first row, and children, but not adults, increased time by larger increments on subsequent rows. For children, both the initial row (automaticity index) and slope (sustained controlled processing index) of the trajectory differentiated the classes. For adults, only the initial row separated the classes. The longest time was on row 3 for RAN and row 4 for RAS. For the typically developing 5th graders, close in age to the children with dyslexia, the trajectories were flatter than for children with dyslexia and only the slower class (4%) showed the peak on row 4. For children with dyslexia, inhibition predicted RAN slope within the slower latent class and phonological working memory predicted RAS slope for both latent classes. For adults with dyslexia, inhibition and phonological working memory differentiated both latent classes on RAN intercept and RAS slope. Taken together, RAN, which may assess the phonological loop of working memory, and RAS, which may assess the central executive in working memory, may explain the timing deficit in dyslexia in sustaining coordinated orthographic-phonological processing over time.

朦胧诗命名的意义及其限度

1970年代末,朦胧诗以异端的呐喊给那个时代带来了难得的思想冲击力。朦胧诗的命名表达了当时诗歌的外在美学特征,暗示了当时诗歌创作环境的艰难,而且展示诗歌内容揭示了人内心的隐秘、直接指向心灵的品读的特质,命名在这些意义上很好地传达了它自身的涵义。但是当时代过往,朦胧本身的含混意指使得其之后的诗歌在某些方面难以逃越它的美学牢笼,成为新诗歌发展的桎梏。回到朦胧诗命名的现场,考察朦胧诗命名的内涵、直击命名活动本身,可以清晰地触摸诗歌发展的脉搏,有益于对当代诗歌发展的困境进行更好的思索和考量。
