Rapid Naming Components and Their Relationship With Phonological Awareness,Orthographic Knowledge,Speed of Processing,and Different Reading Outcomes

This study examines (a) how rapid automatized naming (RAN) speed components—articulation time and pause time—predict reading accuracy and reading fluency in Grades 2 and 3, and (b) how RAN components are related to measures of phonological awareness, orthographic knowledge, and speed of processing. Forty-eight children were administered RAN tasks in Grades 1, 2, and 3. Results indicated that pause time was highly correlated with both reading accuracy and reading fluency measures and shared more of its predictive variance with orthographic knowledge than with phonological awareness or speed of processing. In contrast, articulation time was only weakly correlated with the reading measures and was rather independent from any processing skill at any point of measurement.     

Rapid Naming and Phonemic Awareness: Contributions to Reading,Spelling, and Orthographic Knowledge

The double-deficit hypothesis suggests that deficient skills on two dimensions, rapid naming and phonemic awareness, are associated with poor reading. We studied the reading, spelling, and orthographic skills of Grade 3 children who met our criteria for double asset (DA), single phonological deficit (PD), single naming speed deficit (NSD), and double deficit (DD) groups. Analyses of variance revealed main effects of each factor, oftentimes modified by significant interactions, on the varied achievement measures. All deficit groups performed below the DA children. Compared to children with NSD, children with PD (a) were less accurate decoders, (b) were faster readers, (c) had weaker spelling dictation, and (d) had comparably poor spelling recognition scores. Children with DD showed a mixed pattern of stronger, equal, or weaker skills compared to younger reading level controls.     

Development of Bilingual Phonological Awareness in Spanish-Speaking English Language Learners: The Roles of Vocabulary,Letter Knowledge,and Prior Phonological Awareness

Theories concerning the development of phonological awareness place special emphasis on lexical and orthographic knowledge. Given the large degree of variability in preschool classrooms that house Spanish-speaking English language learners (ELL), this study controlled for classroom effects by removing classroom means and covariances based on 158 children from 40 classrooms. Path analyses of the child-level covariance matrices tested the extent to which vocabulary and letter knowledge in each language predicted growth in English and Spanish phonological awareness of 130 preschool-age, Spanish-speaking ELLs. Results supported cross-linguistic effects of prior phonological awareness and Spanish vocabulary in the development of bilingual phonological awareness. Implications for theory, instruction, and research methods are discussed.     

Brain Activity During Performance of Naming Tasks: Comparison Between Dyslexic and Regular Readers

This research was aimed at contributing to the current understanding of the underlying factors of naming speed and the causes of naming speed deficits. Forty regular readers and 40 dyslexic university students participated in the study. Electrophysiological (Event-Related Potentials [ERPs]) and behavioral measures were employed. Behavioral baseline tasks assessed general ability, reading skills, reading-related cognitive abilities, and standard Rapid Automatized Naming (RAN) and Rapid Alternating Stimulus tests. ERP tasks included letter and object naming tasks adapted for electrophysiological research presentation. The dyslexics were significantly slower and less accurate than the controls on most of the baseline measures. On all the naming tasks, the peak ERP latencies were elicited later, reaction times were longer, and the P300 latency width was wider among the dyslexics as compared to the regular readers. On the choice reaction time naming tasks, accuracy for both groups was almost perfect. When naming presentation time was controlled by the experiment, the dyslexics were significantly less accurate than the controls. Our data indicated that effective naming speed was related to an earlier P200 latency peak among regular readers and to an earlier P300 latency peak and narrower area component activation in the dyslexic group. The results from this study suggest that effective RAN speed among regular readers might be a result of efficient processing of RAN information at the input stage of stimulis perception and evaluation as well as of updating and processing the information in short-term memory among dyslexics.     

Cross-Language Transfer of Phonological Awareness and Letter Knowledge: Causal Evidence and Nature of Transfer

Using a randomized control trial, this study examined the causal evidence of cross-language transfer of phonological awareness and letter knowledge (names and sounds) using data from multilingual 1st-grade children (N = 322) in Kenya. Children in the treatment condition received an 8-week instruction on phonological awareness and letter knowledge in Kiswahili. The comparison group received business-as-usual classroom instruction. Children in the treatment condition showed greater improvement in phonological awareness and letter-sound knowledge in Kiswahili and English (positive transfer; effect sizes from .37 to .95), whereas a negative effect was found in letter-name knowledge (interference; effect size, g = .27). No effects were found in reading, nor did the results vary by moderators (e.g., Kiswahili vocabulary). Path analyses revealed divergent patterns of results for different outcomes. Results provide causal evidence for cross-language transfer of phonological awareness and letter knowledge and offer important theoretical and practical implications.     

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.     

Phonological Awareness and Rapid Automatized Naming as Longitudinal Predictors of Reading in Five Alphabetic Orthographies with Varying Degrees of Consistency

ABSTRACT

Although phonological awareness (PA) and rapid automatized naming (RAN) are confirmed as early predictors of reading in a large number of orthographies, it is as yet unclear whether the predictive patterns are universal or language specific. This was examined in a longitudinal study across Grades 1 and 2 with 1,120 children acquiring one of five alphabetic orthographies with different degrees of orthographic complexity (English, French, German, Dutch, and Greek). Path analyses revealed that a universal model could not be confirmed. When we specified the best-fitting model separately for each language, RAN was a consistent predictor of reading fluency in all orthographies, whereas the association between PA and reading was complex and mostly interactive. We conclude that RAN taps into a language-universal cognitive mechanism that is involved in reading alphabetic orthographies (independent of complexity), whereas the PA–reading relationship depends on many factors like task characteristics, developmental status, and orthographic complexity.

Phonological Awareness and Rapid Naming Skills of Children with Reading Disabilities and Children with Reading Disabilities Who Are At Risk for Mathematics Difficulties

Limited research has examined the skills of children with a reading disability (RD) and children with RD and a mathematics disability (MD). Even less research has examined the phonological awareness (PA) and rapid automatized naming (RAN) skills in these two groups of children and how these skills relate to reading and math achievement. Additionally, various classification criteria are frequently implemented to classify children with MD. The purpose of this study, therefore, was to examine the PA and RAN skills in children who met different criteria for RD only and children with RD who are at risk for mathematics difficulties (MDR). Participants were 114 second‐ or third‐grade students with RD from public elementary schools in three large metropolitan areas. Students were classified as at risk for mathematics difficulties utilizing a 25th‐percentile cutoff and a 15th‐percentile cutoff as assessed by the KeyMath‐Revised Test ( Connolly, 1988 ). A series of PA and RAN measures were administered along with a range of reading and mathematics measures. Hierarchical regression analyses indicated that children with RD only evidenced a different pattern of results compared to children with RD + MDR. Additionally, using a more stringent criterion to classify children at risk for mathematics difficulties resulted in a differential pattern of results when compared to a less stringent classification criterion.     

The Association of Rapid Temporal Perception With Orthographic and Phonological Processing in Children and Adults With Reading Impairment

Adults and children with reading impairment (N = 67) were administered a rapid auditory task, a rapid visual task, and a battery of orthographic and phonological tasks. Our results support a differential development model of reading disability that argues that deficits in rapid auditory ability in children are primarily associated with problems in phonological processing, whereas deficits in rapid visual ability in children are primarily associated with problems in orthographic processing (Farmer & Klein, 1995). In contrast to the children, the adults showed a strong relation between rapid auditory ability and both orthographic and phonological processing. These results suggest that continued deficits in auditory ability may have a pervasive and negative impact on word processing in general. In addition, adults did not exhibit a relation between rapid visual ability and orthographic-processing problems. Orthographic-processing deficits may result from a reading delay condition that can be overcome with increased reading exposure (Harm & Seidenberg, 1999).

语音和字形信息对汉语语义加工的影响

通过对汉语句尾歧义字的行为实验研究,探讨汉字字形、语音、语义之间的关系。选择与中心末尾字(如"雨")同音("语")、形似("两")以及无关控制("哥")的干扰末尾字,让被试判断句子是否语义正确。行为数据表明,形似组和同音组有显著的不同:形似组的反应时长于同音组,正确率也低于同音组。行为实验的结果说明,在汉语句尾歧义字的实验模式中,人们对于形的加工要比同音字困难,在对末尾字不匹配句的语义判断中字形的干扰作用大于语音的干扰作用,而这与对英语的研究结果是相反的。     

The Contribution of Visual Sensitivity,Phonological Processing,and Nonverbal IQ to Children's Reading

It has been suggested that the differences observed for dyslexic readers compared to normal readers on tasks measuring visual sensitivity may simply be the result of differences between the two groups in general cognitive ability and/or attentional engagement. One common way to accommodate this proposal is to match normal and dyslexic readers on IQ. However, an explicit test of this suggestion is to take normal and dyslexic readers who differ on IQ—where IQ would be expected to explain reading ability—and determine if visual sensitivity can still account for reading skill, even when IQ is taken into account. In this study we explored the relative contributions of nonverbal IQ, visual sensitivity as measured by sensitivity to the frequency doubling illusion, and phonological and irregular word reading to reading ability. Visual sensitivity explained a significant amount of variance in reading ability, over and above nonverbal IQ, accounting for 6% of the unique variance in reading ability. Moreover, visual sensitivity was related primarily to irregular word reading rather than to nonsense word decoding. This study demonstrates that low-level visual sensitivity plays an intrinsic role in reading aptitude, even when IQ differences between normal and dyslexic readers are contrived to maximize the contribution of IQ to reading skill. These results challenge the suggestion that impaired visual sensitivity may be epiphenomenal to poor reading skills.

Beginning Reading by Teaching in Rime Analogy: Effects on Phonological Skills,Letter-Sound Knowledge,Working Memory,and Word-Reading Strategies

Prereading kindergartners were assigned to groups that varied experience with (a) the rime analogy reading strategy; (b) the implicated prereading skills of rhyming, initial phoneme identity, and letter-sounds; or (c) a control group. Teaching in the rime analogy strategy and the prereading skills resulted in more reading than teaching in the rime analogy strategy or prereading skills alone. Many children developed the untaught abilities of medial and final phoneme identity and the letter recoding reading strategy. Children with high prereading skill levels read the most words, and the use of specific prereading skills varied across different reading word types. Working memory was unrelated to increases in prereading skills or reading. Children were able to generalize the rime analogy strategy to read words with unfamiliar rime spellings.

Phoneme Awareness,Visual-Verbal Paired-Associate Learning,and Rapid Automatized Naming as Predictors of Individual Differences in Reading Ability

This study examines the concurrent relationships between phoneme awareness, visual-verbal paired-associate learning, rapid automatized naming (RAN), and reading skills in 7- to 11-year-old children. Path analyses showed that visual-verbal paired-associate learning and RAN, but not phoneme awareness, were unique predictors of word recognition, whereas visual-verbal paired-associate learning, RAN, and phoneme awareness were predictors of nonword reading. These results suggest that visual-verbal paired-associate learning, RAN, and phoneme awareness tap related but far-from-identical processes and are important predictors of different aspects of reading skills in children.

Antecedents of Maternal Sensitivity During Distressing Tasks: Integrating Attachment,Social Information Processing,and Psychobiological Perspectives

Predictors of maternal sensitivity to infant distress were examined among 259 primiparous mothers. The Adult Attachment Interview, self‐reports of personality and emotional functioning, and measures of physiological, emotional, and cognitive responses to videotapes of crying infants were administered prenatally. Maternal sensitivity was observed during three distress‐eliciting tasks when infants were 6 months old. Coherence of mind was directly associated with higher maternal sensitivity to distress. Mothers' heightened emotional risk was indirectly associated with lower sensitivity via mothers' self‐focused and negative processing of infant cry cues. Likewise, high physiological arousal accompanied by poor physiological regulation in response to infant crying was indirectly associated with lower maternal sensitivity to distress through mothers' self‐focused and negative processing of infant cry cues.
