Phonological and semantic processes influence beginning readers' ability to learn to read words

Neural correlates of reading aloud on the autism spectrum

Individuals with autism can show intact decoding (i.e., ability to recognize and pronounce written words accurately). However, reading comprehension (i.e., ability to infer meaning from written text) in autistic individuals is often lower than expected based on age or grade level. Having intact decoding skills despite potentially atypical reading comprehension suggests altered reading pathways in autism, particularly when processing semantics (i.e., word meaning). To test for neural differences in word processing between autistic and non-autistic younger adults, we examined behavioral and neural responses to reading aloud words and pronounceable nonsense words (pseudowords). Additionally, we manipulated word imageability, word frequency, and word and pseudoword spelling-sound consistency as probes for different components (i.e., orthography, phonology and semantics) of the reading system. Behaviorally, the autistic group had a greater reduction in reaction time as word imageability increased. Neurally, pseudoword consistency effects, a probe of spelling-sound mappings without semantics, were only observed in the autistic group, where increased consistency was associated with decreased activity in bilateral intraparietal sulcus. Also compared to the non-autistic group, the autistic group showed greater effects of word consistency, where increasing word consistency was associated with increasing activation in the bilateral posterior superior temporal gyrus and ventral occipitotemporal cortex. Finally, the autistic group showed stronger effects of pseudoword consistency than the non-autistic group, that is increasing pseudoword consistency was associated with decreasing activation in the left ventral occipitotemporal cortex. Together, these results point to differences in how neural resources are used for reading, with more bilateral areas recruited during spelling-sound decoding in autistics to achieve comparable performance to non-autistics.

Modeling Complex Word Reading: Examining Influences at the Level of the Word and Child on Mono- and Polymorphemic Word Reading

Purpose

The probability of a child reading a word correctly is influenced by both child skills and properties of the word. The purpose of this study was to investigate child-level skills (set for variability and vocabulary), word-level properties (concreteness), word structure (mono- vs. polymorphemic), and interactions between these properties and word structure within a comprehensive item-level model of complex word reading. This study is unique in that it purposely sampled both mono- and polymorphemic polysyllabic words.

Method

A sample of African American (n = 69) and Hispanic (n =6) students in grades 2-5 (n =75) read a set of mono- and polymorphemic polysyllabic words (J=54). Item-level responses were modeled using cross-classified generalized random-effects models allowing variance to be partitioned between child and word while controlling for other important child factors and word features.

Results

Set for variability and the interaction between concreteness and word structure (i.e., mono- vs. polymorphemic) were significant predictors. Higher probabilities of reading poly- over monomorphemic words were identified at lower levels of concreteness with the opposite at higher levels of concreteness.

Conclusions

Results indicate important predictors at both the child- and word-level and support the importance of morphological structure for reading abstract polysyllabic words.

Semantics impacts response to phonics through spelling intervention in children with dyslexia

We examined the response to a phonics through spelling intervention in 52 children with dyslexia by analyzing their phonological, morphological, and orthographical spelling errors both before and after the intervention whereas their spelling errors before the intervention were compared with those of 105 typically developing spellers. A possible compensatory role of semantics on the intervention effects was also investigated. Results showed that before the intervention, children with dyslexia and the typically developing children both made most morphological errors, followed by orthographic and phonological errors. Within each category, children with dyslexia made more errors than the typically developing children, with differences being largest for phonological errors. Children with dyslexia with better developed semantic representations turned out to make less phonological, morphological, and orthographic errors compared with children with dyslexia with less developed semantic representations. The intervention for children with dyslexia led to a reduction of all error types, mostly of the orthographic errors. In addition, semantics was related to the decline in phonological, morphological, and orthographic spelling errors. This study implicates that semantic stimulation could benefit the spelling development of children at risk for or with dyslexia.

Individual differences in learning the regularities between orthography, phonology and semantics predict early reading skills

Statistical views of literacy development maintain that proficient reading requires the assimilation of myriad statistical regularities present in the writing system. Indeed, previous studies have tied statistical learning (SL) abilities to reading skills, establishing the existence of a link between the two. However, some issues are currently left unanswered, including questions regarding the underlying bases for these associations as well as the types of statistical regularities actually assimilated by developing readers. Here we present an alternative approach to study the role of SL in literacy development, focusing on individual differences among beginning readers. Instead of using an artificial task to estimate SL abilities, our approach identifies individual differences in children's reliance on statistical regularities as reflected by actual reading behavior. We specifically focus on individuals' reliance on regularities in the mapping between print and speech versus associations between print and meaning in a word naming task. We present data from 399 children, showing that those whose oral naming performance is impacted more by print-speech regularities and less by associations between print and meaning have better reading skills. These findings suggest that a key route by which SL mechanisms impact developing reading abilities is via their role in the assimilation of sub-lexical regularities between printed and spoken language -and more generally, in detecting regularities that are more reliable than others. We discuss the implications of our findings to both SL and reading theories.

Examining the role of imageability and regularity in word reading accuracy and learning efficiency among first and second graders at risk for reading disabilities

This study explored word reading accuracy and word learning efficiency in first- and second-grade students (N = 125). In two experiments, students participated in a short training exposing them to words that varied on orthographic regularity and imageability. In Experiment 1 the form of word feedback was manipulated (phonemic vs. whole word), whereas in Experiment 2 pretraining exposure was manipulated (training on meaning vs. imageability). Crossed random effects models were used to explore child- and item-level predictors related to number of exposures to mastery, posttest word reading performance, and maintenance performance after 1 week. Results from Experiment 1 indicate that imageability plays a role in irregular word learning. Results from Experiment 2 suggest that students who received imageability training required fewer exposures to reach mastery. There was a significant interaction between initial word reading skill and condition, with students with low word reading skills requiring fewer exposures for mastery if they were in the imageability condition. Overall, these findings suggest that word imageability significantly affects both word reading accuracy and rate of word learning.

Hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading.

What Is the Influence of Morphological Knowledge in the Early Stages of Reading Acquisition Among Low SES Children? A Graphical Modeling Approach

Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding), before reading comprehension can be reliably assessed. We assessed listening comprehension, receptive vocabulary, phoneme awareness, morphological awareness as well as decoding, word reading and non-verbal IQ in 703 French first-graders from low-SES families after 3 months of formal schooling (November). Awareness of derivational morphology was assessed using three oral tasks: Relationship Judgment (e.g., do these words belong to the same family or not? heat-heater … ham-hammer); Lexical Sentence Completion [e.g., Someone who runs is a …? (runner)]; and Non-lexical Sentence Completion [e.g., Someone who lums is a…? (lummer)]. The tasks differ on implicit/explicit demands and also tap different kinds of morphological knowledge. The Judgement task measures the phonological and semantic properties of the morphological relationship and the Sentence Completion tasks measure knowledge of morphological production rules. Data were processed using a graphical modeling approach which offers key information about how skills known to be involved in learning to read are organized in memory. This modeling approach was therefore useful in revealing a potential network which expresses the conditional dependence structure between skills, after which recursive structural equation modeling was applied to test specific hypotheses. Six main conclusions can be drawn from these analyses about low SES reading acquisition: (1) listening comprehension is at the heart of the reading acquisition process; (2) word reading depends directly on phonemic awareness and indirectly on listening comprehension; (3) decoding depends on word reading; (4) Morphological awareness and vocabulary have an indirect influence on word reading via both listening comprehension and phoneme awareness; (5) the components of morphological awareness assessed by our tasks have independent relationships with listening comprehension; and (6) neither phonemic nor morphological awareness influence vocabulary directly. The implications of these results with regard to early reading acquisition among low SES groups are discussed.

Phonemic feature involvement in lexical access in grades 3 and 5: Evidence from visual and auditory lexical decision tasks

Numerous studies have evidenced the involvement of the phonological code during visual word recognition not only in skilled adult readers but also in child readers. Moreover, in skilled adult readers, visual word processing has been shown to be sensitive to phonetic details such as phonemic features (e.g., manner of articulation, place of articulation, voicing and nasality in French) which are typically involved in phonological lexicon access during speech processing. In contrast, it is not known whether and when visual word recognition is affected by phonemic features during learning to read. The present study investigates this issue in third and fifth graders. A lexical decision task was performed in visual and auditory modalities. Targets were French words (e.g., piano [piano]) and pseudowords created from target words. Mismatching was on the first phoneme. There were one-feature phoneme mismatch pseudowords (e.g., tiano) and multiple-feature phoneme mismatch pseudowords (e.g., liano). The pseudowords were used as a marker of the sensitivity to phonemic features in phonological lexicon access. Phonemic feature effects were found in visual and auditory lexical decision tasks in both grades, indicating that phonological lexicon access involves phonemic features in print processing as in speech processing. In contrast, the absence of difference between both grades seems to indicate that this effect is independent of age or, more precisely, of phonological development and reading performance.

Growth of Word and Pseudoword Reading Efficiency in Alphabetic Orthographies: Impact of Consistency

Word and pseudoword reading are related abilities fundamental to reading development in alphabetic orthographies. They are respectively assumed to index children's orthographic representations of words, which are in turn acquired through the underlying "self-teaching mechanism" of alphabetic pseudoword decoding. Little is known about concurrent growth trajectories of these skills in the early grades among children learning different alphabetic orthographies. In the present study, between- and within-group latent growth models of word and pseudoword reading efficiency were tested on data spanning Grades 1 and 2 from learners of the inconsistent English and consistent Czech and Slovak orthographies. Several language-general patterns emerged. Significant growth was observed for both skills in all languages. Growth was faster for word than pseudoword reading efficiency, and strong lexicality effects that increased over time were obtained across languages. Language-specific patterns were also found. In line with predictions about the costs of learning lower-consistency orthographies, readers of English experienced relatively slower growth on both reading skills. However, their lag was smaller, and evident only at the latter two time points for word reading. In contrast, on pseudoword reading, the English group performed considerably less well than their Czech and Slovak peers at every time point. Thus, weaker decoding skills were the main contributor to the larger lexicality effects of the English group. These findings are considered within the frame of recent theorizing about the effect of orthographic consistency on decoding as a self-teaching mechanism in alphabetic reading acquisition.

The role of phonological awareness and letter-sound knowledge in the reading development of children with intellectual disabilities

Our study investigated if phonological awareness and letter-sound knowledge were predictors of reading progress in children with intellectual disabilities (ID) with unspecified etiology. An academic achievement test was administered to 129 children with mild or moderate ID when they were 6-8 years old, as well as one and two school years later. Findings indicated that phonological awareness and letter-sound knowledge at 6-8 years of age predicted progress in word and non-word reading after one school year and two school years after controlling for IQ, age, expressive vocabulary, spoken language, and type of placement. Phonological awareness and letter-sound knowledge at 6-8 years of age also predicted progress in reading comprehension after one school year and two school years. These findings suggest that training phonological awareness skills combined with explicit phonics instruction is important to foster reading progress in children with mild and moderate ID with unspecified etiology.

The interface between spoken and written language: developmental disorders

We review current knowledge about reading development and the origins of difficulties in learning to read. We distinguish between the processes involved in learning to decode print, and the processes involved in reading for meaning (reading comprehension). At a cognitive level, difficulties in learning to read appear to be predominantly caused by deficits in underlying oral language skills. The development of decoding skills appears to depend critically upon phonological language skills, and variations in phoneme awareness, letter-sound knowledge and rapid automatized naming each appear to be causally related to problems in learning to read. Reading comprehension difficulties in contrast appear to be critically dependent on a range of oral language comprehension skills (including vocabulary knowledge and grammatical, morphological and pragmatic skills).

Phonological Segmentation Assessment Is Not Enough

Despite extensive research on phonological awareness and reading, there has been little effort to study practical questions that would assist practitioners regarding the choice and interpretation of the phonological awareness tests available to them. This study examined the relationship between decoding (real and pseudowords) and three phonological awareness tests (segmentation, blending, and manipulation) taken from the Comprehensive Test of Phonological Processing (CTOPP) with an unselected population of first grade ( n = 67) and second grade ( n = 49) students. Segmentation displayed the weakest correlation with reading and accounted for no statistical variance in reading beyond what was found in the blending test. It also failed to account for a substantial amount of variance in reading that is captured by the manipulation test. Despite its popularity in educational contexts, phonological segmentation may be less useful than phonological manipulation or blending in assessing the phonological substrates of reading at these grade levels.

Form-meaning links in the development of visual word recognition

Learning to read takes time and it requires explicit instruction. Three decades of research has taught us a good deal about how children learn about the links between orthography and phonology during word reading development. However, we have learned less about the links that children build between orthographic form and meaning. This is surprising given that the goal of reading development must be for children to develop an orthographic system that allows meanings to be accessed quickly, reliably and efficiently from orthography. This review considers whether meaning-related information is used when children read words aloud, and asks what we know about how and when children make connections between form and meaning during the course of reading development.

Beginning readers activate semantics from sub-word orthography

Two experiments assessed whether 7-year-old children activate semantic information from sub-word orthography. Children made category decisions to visually-presented words, some of which contained an embedded word (e.g., hip in ship). In Experiment 1 children were slower and less accurate to classify words if they contained an embedded word related in meaning to the category (e.g., slower to reject ship as a 'body part' than an 'animal'), especially when the embedded word was higher in frequency than the carrier word. This demonstrates that young children activate semantic information from sub-word orthographic representations, and that they do so from the relatively early stages of learning to read. Experiment 2 replicated this effect. Furthermore, we observed semantic interference regardless of whether the embedded word shared its pronunciation with the carrier (e.g., the hip in ship) or not (e.g., the crow in crown), and regardless of its position within the carrier, suggesting that interference was not dependent on phonological mediation. These findings show that by 7-years-of age, children have begun to establish an orthographic system that is capable of activating sub-word orthographic patterns, strong enough to connect with meaning, when reading words silently.

Learning to Read Words

The ease with which we process the written word belies its complexities and makes it easy to forget that it is a highly skilled behaviour and one that takes time to master. In this paper, I argue that our ability to read words has its roots in our capacity for language. Good progress has been made towards understanding how children discover the systematic relationship between speech sounds and the letters used to represents those sounds, very early in reading development. However, we understand much less about how beginning readers become skilled readers. To understand this, I argue that it is important to view the visual word recognition system within the context of a broader language system, one that incorporates a rich network of semantic and episodic knowledge.

The Development of Phonological Awareness by Braille Users: A Review of the Research

This article presents a review of research on the development of phonological awareness by braille readers. The review determined that the relationship between phonological awareness and braille is uncertain because of the lack of commonality among the studies, the extent of contradictory findings, and the small number of studies involving beginning braille readers.

Phonological awareness and the use of phonological similarity in letter-sound learning

The effects of the phonological similarity between a letter sound and the sound in a spoken word, and phonological awareness on letter-sound learning were examined. Two groups of 41 kindergartners were taught four letter sounds. First, both groups had to learn the associations between four symbols and four familiar words. Next, both groups were taught the letter sounds that were paired to these same symbols. Each letter sound corresponded to the first sound of the word that was previously associated with that symbol in the phonological similarity group, whereas such a relation was absent in the other group. In addition, measures of vocabulary, letter knowledge, and phonological awareness were administered. Phonological similarity facilitated letter-sound learning. Individual differences in phonological awareness had a strong effect on letter-sound learning even after current letter knowledge was controlled. Unexpectedly, the effects of phonological awareness and the ability to use phonological similarity on letter-sound learning were found to be independent.

Which children benefit from letter names in learning letter sounds?

Typical U.S. children use their knowledge of letters' names to help learn the letters' sounds. They perform better on letter sound tests with letters that have their sounds at the beginnings of their names, such as v, than with letters that have their sounds at the ends of their names, such as m, and letters that do not have their sounds in their names, such as h. We found this same pattern among children with speech sound disorders, children with language impairments as well as speech sound disorders, and children who later developed serious reading problems. Even children who scored at chance on rhyming and sound matching tasks performed better on the letter sound task with letters such as v than with letters such as m and h. Our results suggest that a wide range of children use the names of letters to help learn the sounds and that phonological awareness, as conventionally measured, is not required in order to do so.

The influence of semantic processing on phonological decisions in children and adults: a magnetoencephalography (MEG) study

PURPOSE

To examine the behavioral effects and neural activation patterns associated with implicit semantic processing influences on phonological judgments during reading in children and adults.

METHOD

Whole-head magnetoencephalography (MEG) recordings were obtained from 2 groups, children (9-13 years) and adults, performing a homophone judgment task. The stimuli consisted of pairs of sequentially presented written words that were either homophones, synonym foils, or unrelated control words.

RESULTS

The difference in the time taken to respond to synonym pairs relative to control pairs of stimuli, called the semantic interference effect (SIE), was, on average, 24 ms for adults and 86 ms for children. Source analysis of the MEG data using minimum-norm estimation (MNE) yielded less activation in the adults for the synonym condition compared with the control condition in right anterior temporal and inferior frontal cortex 300-500 ms after the onset of the 2nd word in a pair, suggestive of semantic priming as well as inhibition of the SIE. A similar priming effect was observed for the children in left-anterior temporal cortex.

CONCLUSION

The observed group differences in the magnitude of the SIE and brain activation patterns may reflect developmental differences in the effects of semantic information on phonological decisions during word processing.

Longitudinal case-studies of developmental dyslexia in Norwegian

This study examined retrospectively the preschool cognitive and linguistic profiles and emergent literacy skills in four Norwegian dyslexic children. The aim was to identify prognostic indicators that were associated with the reading impairments observed in an earlier study of these children. In comparison to a control group of at-risk children who were normal readers at age 10, three of the four dyslexic children exhibited either stagnation or a decline in speech accuracy in the presence of a vocabulary growth spurt at age 2-3 years. Skills in phonological awareness seemed to vary inconsistently with both early speech development and emergent literacy across the four cases. Delayed development in emergent literacy turned out to be the most potent prognostic indicator of later reading disorders. The study was guided by lexical restructuring theories of dyslexia.

Becoming a fluent and automatic reader in the early elementary school years

The goals of this study were to (a) develop an empirically based model regarding the development of fluent and automatic reading in the early elementary school years and (b) determine whether fluent text-reading skills provided benefits for reading comprehension beyond those accounted for by fluent word decoding. First-, second-, and third-grade children completed a series of reading tasks targeting word and nonword processing, text reading, spelling knowledge, autonomous reading, and reading comprehension. Structural equation modeling was carried out to evaluate how these skills operated together to produce fluent text reading and good comprehension. Evidence supported a simple reading fluency model for the early elementary school years suggesting that fluent word and text reading operate together with autonomous reading to produce good comprehension.

Developmental dyslexia in Norwegian: evidence from single-case studies

This study provides detailed descriptions of the reading impairments in four 10-year-old Norwegian children with dyslexia. In all four cases reading comprehension was well in advance of the children's slow and inaccurate word-recognition skills. Phonological decoding (as assessed by pseudohomophone and nonword reading) appeared relatively unimpaired in three of the dyslexic cases, both in terms of speed and accuracy. However, reading errors showed that these children had particular difficulties with both phoneme length and phoneme quality awareness in reading. A 'phonemic identification deficit' account for developmental dyslexia in Norwegian children is suggested.

Automatic and controlled processing of acoustic and phonetic contrasts

Changes in the temporal properties of the speech signal provide important cues for phoneme identification. An impairment or inability to detect such changes may adversely affect one's ability to understand spoken speech. The difference in meaning between the Finnish words tuli (fire) and tuuli (wind), for example, lies in the difference between the duration of the vowel /u/. Detecting changes in the temporal properties of the speech signal, therefore, is critical for distinguishing between phonemes and identifying words. In the current study, we tested whether detection of changes in speech sounds, in native Finnish speakers, would vary as a function of the position within the word that the informational changes occurred (beginning, middle, or end) by evaluating how length contrasts in segments of three-syllable Finnish pseudo-words and their acoustic correlates were discriminated. We recorded a combination of cortical components of event-related brain potentials (MMN, N2b, P3b) along with behavioral measures of the perception of the same sounds. It was found that speech sounds were not processed differently than non-speech sounds in the early stages of auditory processing indexed by MMN. Differences occurred only in later stages associated with controlled processes. The effects of position and attention on speech and non-speech stimuli are discussed.

Developmental Dyslexia and Specific Language Impairment: Same or Different?

Developmental dyslexia and specific language impairment (SLI) were for many years treated as distinct disorders but are now often regarded as different manifestations of the same underlying problem, differing only in severity or developmental stage. The merging of these categories has been motivated by the reconceptualization of dyslexia as a language disorder in which phonological processing is deficient. The authors argue that this focus underestimates the independent influence of semantic and syntactic deficits, which are widespread in SLI and which affect reading comprehension and impair attainment of fluent reading in adolescence. The authors suggest that 2 dimensions of impairment are needed to conceptualize the relationship between these disorders and to capture phenotypic features that are important for identifying neurobiologically and etiologically coherent subgroups.

Development of phonological and orthographic processing in reading aloud, in silent reading, and in spelling: a four-year longitudinal study

The development of phonological and orthographic processing was studied from the middle of Grade 1 to the end of Grade 4 (age 6; 6-10 years) using the effects of regularity and of lexicality in reading aloud and in spelling tasks, and using the effect of pseudohomophony in a silent reading task. In all the tasks, signs of reliance on phonological processing were found even when indicators of reliance on orthographic processing appeared. Multiple regression analyses were conducted to determine which early skills predict later reading achievement. Pseudoword and irregular word scores were used as measures for phonological and orthographic skills, respectively. Only middle of Grade 1 phonological reading skills accounted for independent variance in end of Grade 4 orthographic skills. Conversely, from the middle to the end of Grade 1, and from the end of Grade 1 to the end of Grade 4, both orthographic and phonological skills accounted for independent variance in later orthographic skills. In the prediction of phonological skills, only the unique contribution of earlier phonological skills was significant. Thus, phonological and orthographic processing appear to be reciprocally related, rather than independent components of written word recognition. However, very early reliance on the phonological procedure seems to be the bootstrapping mechanism for reading acquisition.

Word, nonword, and visual paired associate learning in Dutch dyslexic children

Verbal and non-verbal learning were investigated in 21 8-11-year-old dyslexic children and chronological-age controls, and in 21 7-9-year-old reading-age controls. Tasks involved the paired associate learning of words, nonwords, or symbols with pictures. Both learning and retention of associations were examined. Results indicated that dyslexic children had difficulty with verbal learning of both words and nonwords. In addition, analysis of the errors made during nonword learning showed that both phonological errors and general learning errors were distributed similarly for the reading groups. This suggests that nonword learning in dyslexics is slower, but not qualitatively different from normal readers. Furthermore, no differences were found between the dyslexics and age-matched normal readers on non-verbal learning. Long-term retention of the learned visual-verbal associations (both words and nonwords) was not impaired in dyslexic children as compared to normal readers. Finally, phonological awareness ability was assessed. Dyslexics performed worse than age-matched normal readers, but similar to reading-age controls.

Relating print and speech: the effects of letter names and word position on reading and spelling performance

From an early age, children can go beyond rote memorization to form links between print and speech that are based on letter names in the initial positions of words (Treiman & Rodriguez, 1999; Treiman, Sotak, & Bowman, 2001). For example, children's knowledge of the name of the letter t helps them learn that the novel word TM is pronounced as team. Four experiments were carried out to determine whether letter names at the ends of words are equally useful. Four- and five-year-olds derived little benefit from such information in reading (Experiments 1 and 3) or spelling (Experiment 2), although adults did (Experiment 4). For young children, word-final information appears to have less influence on reading and spelling performance than does word-initial information. The results help delineate the circumstances under which children can go beyond a logographic approach in learning about print.

Predicability (ease of predication) as semantic substrate of imageability in reading and retrieval

It was proposed by Jones (1985) that the apparent influence of a word's imageability upon the probability of the word being read correctly by a deep dyslexic person could be understood in terms of an underlying semantic variable, ease of predication (also termed predicability). In a recent critique, de Mornay Davies and Funnell (2000) claim to have identified a number of problems with the ease of predication proposal. It is shown here, however, that it is the critique itself which is fundamentally flawed. In contrast, the predicability approach continues to identify correctly the semantic substrate of apparent effects of imageability upon reading and memory retrieval.

Phoneme awareness is a better predictor of early reading skill than onset-rime awareness

We present the results of a short-term longitudinal study. Children in the early stages of learning to read (5 and 6 year olds) were administered three different tasks (deletion, oddity, and detection) tapping awareness of four phonological units (initial phoneme, final phoneme, onset, and rime). Measures of phoneme awareness were the best concurrent and longitudinal predictors of reading skill with onset-rime skills making no additional predictive contribution once phonemic skills were accounted for. The findings are related to recent controversy over the role of large versus small phonological units as predictors of children's reading skills.

The roles of letter names and letter sounds in connecting print and speech

Three experiments were carried out to examine the cues that are used in learning to read and spell new words. In a reading task (Experiment 1), even preschoolers who could not read simple real words were able to benefit from print-sound relationships that were based on letter names. They found it easier to learn that the made-up word TM was pronounced as 'team" (name condition) than that TM was pronounced as "tame" (sound condition) or as "wide" (visual condition). The letter-name strategy persisted among college students (Experiment 2). In a spelling task (Experiment 3), prereaders and novice readers again did better in the name condition than in the sound condition. The ability to use relationships based on letter sounds emerged later than the ability to use relationships based on letter names. However, sound-based relationships were used to a greater extent in spelling than in reading.
