Phonemic Processes in Children's Listening and Reading Comprehension

Two experiments were conducted to investigate the role of phonemic activation in children's listening and reading comprehension. Phonemically confusing stories were presented in a listening comprehension task to kindergarten and second-grade children and in a reading comprehension task to second-grade children only. Rhymes induced phonemic confusion more consistently than did alliteratives in both the listening and reading tasks at both grade levels, suggesting that rhyme is inherently more confusing than alliteration, and furthermore, that phonemic information is activated in similar ways when children listen and when they read silently. Children's reading skill was also assessed to examine a possible relationship between reading skill and phonemic sensitivity, but no significant interactions between children's reading skill and their sensitivity to phonemic confusion were found in the reading task. In the listening task, all groups showed phonemic confusion in gist recall scores, but prereaders were less likely than readers to exhibit susceptibility to phonemic confusion in verbatim recall scores.     

A developmental perspective on reading dysfunction: Accuracy and rate criteria in the subtyping of dyslexic children

Children referred with specific reading dysfunction were subtyped as accuracy disabled or rate disabled according to criteria developed from an information processing model of reading skill. Multiple measures of oral and written language development were compared for two subtyped samples matched on age, sex, and IQ. The two samples were comparable in reading fluency, reading comprehension, word knowledge, and word retrieval functions. Accuracy disabled readers demonstrated inferior decoding and spelling skills. The accuracy disabled sample proved deficient in their understanding of oral language structure and in their ability to associate unfamiliar pseudowords and novel symbols in a task designed to simulate some of the learning involved in initial reading acquisition. It was suggested that these two samples of disabled readers may be best described with respect to their relative standing along a theoretical continuum of normal reading development.     

Paired-associate learning, phoneme awareness, and learning to read

We report two studies examining the relations among three paired-associate learning (PAL) tasks (visual-visual, verbal-verbal, and visual-verbal), phoneme deletion, and single-word and nonword reading ability. Correlations between the PAL tasks and reading were strongest for the visual-verbal task. Path analyses showed that both phoneme deletion and visual-verbal PAL were unique predictors of a composite measure of single-word reading and of irregular word reading. However, for nonword reading, phoneme deletion was the only unique predictor (and visual-verbal PAL was not a significant predictor). These results are consistent with the view that learning visual (orthography) to phonological mappings is an important skill for developing word recognition skills in reading and that individual differences in this ability can be tapped experimentally by a PAL task.     

How orthographic transparency affects morphological processing in young readers with and without reading disability

This study investigates how orthographic modifications to the stems of complex words affect morphological processing in proficient young Spanish readers and children with reading deficits. In a definition task all children, irrespective of their reading skill, were worse at defining derived words that had an orthographic alteration of the base stem than words with no orthographic alteration. In a go/no‐go lexical decision task, an interaction between base frequency and orthographic alteration was found: base frequency affected derived words with no orthographic alteration more than words with alterations, irrespective of reading skill. Overall, results show that all children benefit from a high frequency base, skilled children outperform children with reading deficits and morphological processing is affected by orthographic alterations similarly in proficient and impaired readers.     

Visual word recognition without central attention: Evidence for greater automaticity with greater reading ability

The present study examined individual differences in the automaticity of visual word recognition. Specifically, we examined whether people can recognize words while central attention is devoted to another task and how this ability depends on reading skill. A lexical-decision Task 2 was combined with either an auditory or visual Task 1. Regardless of the Task 1 modality, Task 2 word recognition proceeded in parallel with Task 1 central operations for individuals with high Nelson-Denny reading scores, but not for individuals with low reading scores. We conclude that greater lexical skill leads to greater automaticity, allowing better readers to more efficiently perform lexical processes in parallel with other attention-demanding tasks.

Individual differences in skilled adult readers reveal dissociable patterns of neural activity associated with component processes of reading

We used fMRI to examine patterns of brain activity associated with component processes of visual word recognition and their relationships to individual differences in reading skill. We manipulated both the judgments adults made on written stimuli and the characteristics of the stimuli. Phonological processing led to activation in left inferior frontal and temporal regions whereas semantic processing was associated with bilateral middle frontal activation. Individual differences in reading subskills were reflected in differences in the degree to which cortical regions were engaged during reading. Variation in sight word reading efficiency was associated with degree of activation in visual cortex. Increased phonological decoding skill was associated with greater activation in left temporo-parietal cortex. Greater reading comprehension ability was associated with decreased activation in anterior cingulate and temporal regions. Notably, associations between reading ability and neural activation indicate that brain/behavior relationships among skilled readers differ from patterns associated with dyslexia and reading development.

Generating inferences from written and spoken language: A comparison of children with visual impairment and children with sight

The two experiments reported here investigated the ability of sighted children and children with visual impairment to comprehend text and, in particular, to draw inferences both while reading and while listening. Children were assigned into ‘comprehension skill’ groups, depending on the degree to which their reading comprehension skill was in line with that predicted by their decoding skill. They then read (either print or Braille) and listened to a series of novel short stories. These were followed by a series of questions, which required either the generation of inferences, or an answer that could be taken literally from the text. The results suggest that children with and without sight are comparable in their ability to draw inferences, and that children with visual impairment show an advantage for literal questions under auditory presentation.     

Development of letter-specific processing: the effect of reading ability

During development, perceptual processing is tuned to inputs in the environment such that certain frequently encountered classes of stimuli are processed more effectively than similar comparison stimuli. Letters represent a class of stimuli that are encountered frequently in the environment, at least in literate cultures. Thus, the present study examined the development of letter-specific processing in children 6-19 years old by comparing the difference between performance on a letter-matching task and an unfamiliar non-letter-matching task in different subject groups. Results revealed an increase in letter-specific processing with development. Moreover, comparisons of letter-specific processing in groups of subjects matched either in age or reading ability indicate that the emergence of letter-specific processing is linked to increased reading skill, rather than increased age per se. Findings support theories of perceptual expertise, which suggest that skilled processing drives the specialization of perceptual mechanisms for certain classes of stimuli.     

Semantic interference in picture naming during dual-task performance does not vary with reading ability

Previous dual-task studies examining the locus of semantic interference of distractor words in picture naming have obtained diverging results. In these studies, participants manually responded to tones and named pictures while ignoring distractor words (picture–word interference, PWI) with varying stimulus onset asynchrony (SOA) between tone and PWI stimulus. Whereas some studies observed no semantic interference at short SOAs, other studies observed effects of similar magnitude at short and long SOAs. The absence of semantic interference in some studies may perhaps be due to better reading skill of participants in these than in the other studies. According to such a reading-ability account, participants’ reading skill should be predictive of the magnitude of their interference effect at short SOAs. To test this account, we conducted a dual-task study with tone discrimination and PWI tasks and measured participants’ reading ability. The semantic interference effect was of similar magnitude at both short and long SOAs. Participants’ reading ability was predictive of their naming speed but not of their semantic interference effect, contrary to the reading ability account. We conclude that the magnitude of semantic interference in picture naming during dual-task performance does not depend on reading skill.     

Evidence for a difference in syntactic knowledge between skilled and less skilled adult readers

In two experiments, we investigated the relationship between reading ability and linguistic knowledge in adults. The results from Experiment 1 showed that good comprehenders performed more accurately than average comprehenders in a syntactic-judgment task that required them to decide whether pairs of words served the same grammatical function in sentences. By contrast, the reader groups performed similarly when required to make semantic judgments about whether pairs of words were related in meaning. In Experiment 2, individuals were classified according to comprehension level and reading speed. Good comprehenders again performed more accurately than average comprehenders in the syntactic task but not the semantic task. We argued that differences in form-class knowledge could be associated with corresponding differences in syntacticprocessing efficiency, and thus with variation in reading-comprehension skill generally.     

Visual spatial skill: a consequence of learning to read?

Does learning to read influence one’s visual skill? In Study 1, kindergartners from Hong Kong, Korea, Israel, and Spain were tested on word reading and a task of visual spatial skill. Chinese and Korean kindergartners significantly outperformed Israeli and Spanish readers on the visual task. Moreover, in all cultures except Korea, good readers scored significantly higher on the visual task than did less good readers. In Study 2, we followed 215 Hong Kong Chinese kindergartners across 1 year, with word reading and visual skills tested twice. In this study, word reading at Time 1 by itself predicted 13% of unique variance in visual skill at Time 2. Together, these results underscore the potential importance of the process of learning to read for shaping one’s visual spatial skill development.     

Cognitive predictors of single-digit and procedural calculation skills and their covariation with reading skill

This study examined the extent to which children's cognitive abilities in kindergarten and their mothers' education predict their single-digit and procedural calculation skills and the covariance of these with reading skill in Grade 4. In kindergarten, we assessed children's (N=178) basic number skills, linguistic skills, and visual attention. In Grade 4, we assessed their calculation and reading skills. Data on children's cognitive ability at 5 years of age and their mothers' level of education were also collected. The results showed that both of the core components of calculation, single-digit and procedural calculation, as well as their covariance with reading, were predicted by unique cognitive factors. Fluency in single-digit calculation and text reading shared an underlying cognitive process, that is, the ability to fluently retrieve verbal or visual-verbal associations from long-term memory. In contrast, procedural calculation was predicted not only by single-digit calculation but also by mother's education and conceptual knowledge of numbers. Overall, the results suggest that a multicomponential approach, including a hierarchical relation among various components, is fruitful when trying to understand the development of mathematical skill and its covariation with reading.     

When children write nonwords to dictation

Skill in written spelling of simple, monosyllabic nonwords was investigated in 9- to 11-year-old English children. Two aspects of their spellings were of interest: first, could they spell these nonwords so that they sounded correct (nonword spelling accuracy), and second, did their spellings show evidence of biasing from words heard earlier in the test sequence? Nonword spelling was poorer for children of this age than for tested adults. Nevertheless, significant biasing occurred in these children's spellings, though not to the same extent as in adults' nonword spellings, and significant correlations emerged between reading age, nonword spelling skill, susceptibility to biasing, and real word spelling skill. Children with a reading age greater than 11 years showed biasing from word spellings that was within range of that reported for adults, and, for these more skilled readers, word spelling accuracy correlated significantly with both susceptibility to biasing and with nonword spelling accuracy. These children were not as accurate as tested adults at spelling nonwords. Children with a reading age below 11 years were poorer at nonword spelling and showed no overall biasing, yet they also showed a significant correlation between word spelling skill and nonword biasing. Together with evidence from the same task from adults with specific spelling disorders, these results suggest that word knowledge had a direct (biasing) and an indirect (general word spelling knowledge) effect on the performance of the nonword spelling task. But although skill in word spelling may be a necessary prerequisite for nonword spelling, it need not always be sufficient.     

Chicken or egg? Untangling the relationship between orthographic processing skill and reading accuracy

There is increasing evidence of a relationship between orthographic processing skill, or the ability to form, store and access word representations, and reading ability. Empirical research to date has not, however, clarified the direction of this relationship. We examined this question in a three-year longitudinal study of children from Grades 1 to 3. We included standard measures of orthographic processing skill, at both the lexical and sublexical level, and word reading accuracy, as well as controls of vocabulary, non-verbal reasoning, and phonological awareness. In all analyses, word reading predicted progress in acquiring orthographic processing skill, regardless of grade level or orthographic processing measure. In contrast, orthographic processing skill did not predict progress in word reading. Our results suggest that, between Grades 1 and 3, children acquire orthographic processing skill through their reading and that this ability, as characterized by the most common tasks used to date, does not play an independent role in supporting reading acquisition.     

KNOWING ABOUT READING BEFORE READING: PRESCHOOL CHILDREN'S CONCEPTS OF READING

This paper reports findings from an investigation of preschool children's concepts about reading. Three tasks related to several basic ideas about reading were presented to 60 preschool children, ranging in age from three to five years. The first task assessed children's ability to identify oral and silent reading. The number of children who correctly identified both forms of reading increased with age, with almost all five‐year‐olds giving accurate responses. The second task was aimed at establishing children's perceptions of their own reading ability. Only four of the 60 children incorrectly evaluated their own reading ability. The third task investigated children's ability to recognize what it is on a page that is read. Three‐year‐olds were, on the whole, quite unaware of the salient information in books. Even among the five‐year‐olds, who performed significantly better than three‐ and four‐year‐olds on this task, some children's responses indicated an ambiguity about the role of print in reading. Suggestions for adults who guide young children through their early experiences with print are drawn from the findings of this investigation.     

Effects of Self-Perception of Reading Skill on Absolute Accuracy of Metacomprehension Judgements

The objective of this study is to investigate the role of self-perception of reading skill as a critical cue for metacomprehension assessment. To achieve our objective, we inspected how self-perception of reading skill explains judgements of reading comprehension and their absolute accuracy. The study results supported our hypotheses: (1) self-perception of reading skill was predictive of metacomprehension predictions even when actual reading skill was controlled for; (2) the extent to which self-perception of reading skill deviated from actual reading skill accounted for the degree to which absolute accuracy of predictions was limited; and (3) more-skilled readers were less likely to overestimate their general reading skill and their reading performance in specific texts than less-skilled readers. However, (4) self-perception of reading skill was more highly related to postdictions than predictions of test performance, which was counter to expectations. We conclude that self-perception of reading skill influences metacomprehension assessments and their absolute accuracy.     

Rapid automatized naming in children referred for evaluation of heterogeneous learning problems: how specific are naming speed deficits to reading disability?

Because the Rapid Automatized Naming (RAN) test reliably predicts reading skill, it is typically viewed as a diagnostic indicator of risk for reading disability (RD). Since most of the work on naming speed has been undertaken within the framework of reading research, however, the extent to which poor RAN is specifically associated with RD or with learning impairment (LI) in general is uncertain. We tested the hypothesis that slow naming speed is specific to RD. Participants were 188 children (ages 7 to 11) referred for evaluation of learning problems. Receiver operating characteristic (ROC) analysis was used to evaluate the utility of the RAN task for classifying children in diagnostic groups. RAN was an excellent tool for detecting risk for learning problems in general, but it was much less effective at distinguishing LI children with and without RD from each other.     

Cognitive processes in children's reading and attention: The role of working memory,divided attention,and response inhibition

Children experiencing attention difficulties have documented cognitive deficits in working memory (WM), response inhibition and dual tasks. Recent evidence suggests however that these same cognitive processes are also closely associated with reading acquisition. This paper therefore explores whether these variables predicted attention difficulties or reading among 123 children with and without significant attention problems sampled from the school population. Children were screened using current WM and attention task measures. Three factors explained variance in WM and attention tasks. Response inhibition tasks loaded mainly with central executive measures, but a dual processing task loaded with the visual‐spatial WM measures. Phonological loop measures loaded independently of attention measures. After controls for age, IQ and attention‐group membership, phonological loop and ‘central processing’ measures both predicted reading ability. A ‘visual memory/dual‐task’ factor predicted attention group membership after controls for age, IQ and reading ability. Results thus suggest that some of the processes previously assumed to be predictive of attention problems may reflect processes involved in reading acquisition. Visual memory and dual‐task functioning are, however, purer indices of cognitive difficulty in children experiencing attention problems.
