Levels of phonological representation in skilled reading and in learning to read

This paper refers to and discusses empiricalevidence supporting the general idea that bothskilled reading and learning to read capitalizeon underlying phonological representations.These representations must be specified interms of degree of abstractness, unitsrepresented and degree of conscious access tothese units. In skilled reading, pre-lexicalrepresentations, at different levels ofphonological structure, are unconsciously,mandatorily and automatically activated, inconnection with correspondent orthographicrepresentations. This process is distinct fromthe intentional and controlled phonologicaldecoding assumed by the classic dual-routemodel. Learning to read may be described as theprogression from conscious phonologicaldecoding, in which phoneme awareness plays acritical role, to the unconscious mapping oforthographic and phonological segments.Phonological dyslexia is related to someanomaly in speech perception capacities, makingit difficult both to develop efficientconscious segmentation abilities andgrapho-phonological decoding. It is suggestedthat this conscious speech segmentation deficitis caused by a lack of appropriate segmentationat the unconscious, perceptual level.

Assessing individual differences in young children

Cognitive styles characterize individuals' personalities as well as their social and cognitive functioning. An assessment of cognitive styles provides an appraisal which extends the assessment of mental performance beyond the levelsof achievement to patterns of cognitive functioning and thus can present another dimension of individual differences in children as the basis for planning and evaluating early childhood programs.     

Developmental and individual differences in Chinese writing

The goal of the present study was to examine the generalizability of a model of the underlying dimensions of written composition across writing systems (Chinese Mandarin vs. English) and level of writing skill. A five-factor model of writing originally developed from analyses of 1st and 4th grade English writing samples was applied to Chinese writing samples obtained from 4th and 7th grade students. Confirmatory factor analysis was used to compare the fits of alternative models of written composition. The results suggest that the five-factor model of written composition generalizes to Chinese writing samples and applies to both less skilled (Grade 4) and more skilled (Grade 7) writing, with differences in factor means between grades that vary in magnitude across factors.     

Developmental change and individual differences in children's multiplication

Age-related change and patterns of individual differences in children's knowledge and skill in multiplication were investigated for students in Grades 4 and 6 (approximately ages 9 and 11, respectively) by examining multiple measures of computational skill, conceptual knowledge, and working memory. Regression analyses revealed that indexes reflecting probability of retrieval and special problem characteristics overshadow other, more general indexes (problem size and frequency of presentation) in predicting solution latencies. Some improvement in the use of conceptual knowledge was evident between Grades 4 and 6, but this change was neither strong nor uniform across tasks. Finally, patterns of individual differences across tasks differed as a function of grade level. The findings have implications for understanding developmental change and individual differences in mathematical cognition.     

Assessment of three-and-a-half-year-old children's emerging phonological awareness in a computer animation context

Four computer-animated tasks were created to analyze the underlying structure of emerging phonological awareness at 3.5 years of age and to explore the factors that influence children's (N = 91) performance on the tasks. Our findings indicated that already at this young age, children are able to master tasks demanding identification, blending, and continuation of phonological units when the tasks are presented in a motivating assessment context. In line with earlier research, children showed higher mastery in dealing with words and syllables than in dealing with phonemes. Targets in the initial position of a word were easier for children to identify than those in the final position. Our analysis provided support for two major dimensions of emerging phonological awareness based on the cognitive operations of the tasks: identification and blending of phonological units.     

A metacognitive view of individual differences in self-regulated learning

Metacognition's roles in self-regulation of cognitive tactics and strategies is explored in relation to five sites where individual difference factors are likely to be observed and affect performance: domain knowledge, knowledge of tactics and strategies, performance of tactics and strategies, regulation of tactics and strategies, and global dispositions. Though the current literature is sparse, tentative hypotheses about kinds of individual differences and their impact are proposed. Directions for future research are noted concerning the need for more sophisticated metacognitively-based models of SRL as a complex collection of individual differences, and some suggestions are made about methodologies for investigating complex, metacognitively regulated approaches to learning.     

Dyslexia in adults: Evidence for deficits in non-word reading and in the phonological representation of lexical items

Difficulties in reading and language skills which persist from childhood into adult life are the concerns of this article. The aims were twofold: (1) to find measures of adult reading processes that validate adults’ retrospective reports of difficulties in learning to read during the school years, and (2) to search for indications of basic deficits in phonological processing that may point toward underlying causes of reading difficulties. Adults who reported a history of difficulties in learning to read (n=102) were distinctly disabled in phonological coding in reading, compared to adults without similar histories (n=56). They were less disabled in the comprehension of written passages, and the comprehension disability was explained by the phonological difficulties. A number of indications were found that adults with poor phonological coding skills in reading (i.e., dyslexia) have basic deficits in phonological representations of spoken words, even when semantic word knowledge, phonemic awareness, educational level, and daily reading habits are taken into account. It is suggested that dyslexics possess less distinct phonological representations of spoken words. This research was supported by a grant from the Danish Research Council to the first author.     

The National Literacy Strategy and individual differences

This is a discussion paper reflecting on the National Literacy Strategy (NLS) after one year of operation. It is argued that, despite claims that it has already had an effect on KS2 SAT (Standardised Assessment Test) performance, it is too soon to make such a judgement. Questions are raised about whether it is wise to use a non‐professional group of assistants to provide the Additional Literacy Support for at risk children in Key Stage 2 or the Key Stage 1 Intervention Programme. It is argued that those children who show atypical development need the most qualified and highly skilled teachers. Finally, it is argued that once the NLS becomes established it will be necessary for all teachers to engage with the research literature so that they teach from a position of professional understanding of the processes involved in reading and writing development.     

From individual differences to dynamic pathways of development

A fruitful way to build upon French-language research on development of analogical and propositional processes in logical reasoning tasks is to use dynamic systems tools to describe and analyze relevant developmental pathways. Issues to address include (1) the characteristics of developmental transitions, such as hysteresis; (2) the nature of growth processes, such as hierarchical development or predator-prey interactions; and (3) the construction of effective scales for measuring change in logical reasoning.     

Explaining individual differences in reading: Theory and evidence

This review focuses on the topic of re-teaching within a formative cycle of instruction, in regular classroom settings. Although re-teaching is assumed integral to effective teaching, learning, and formative assessment, effective re-teaching is but scantly described in pedagogical literature and has been neglected in empirical research. Teachers and school systems seeking to improve student achievement, especially for lower-achieving students, would be well-served by more information and evidence about effective re-teaching. Accordingly, this review follows a defined and replicable protocol, using four questions to explore the extent and detail of existing information about re-teaching and use this information as the basis for suggestions of approaches and strategies for effective re-teaching. The importance of effective re-teaching for students with learning difficulties is emphasised and the potential benefits of effective re-teaching on academic self-concept and motivation for students, and on teacher effectiveness, are discussed. Collecting evidence from practice and the need to quantify the effectiveness of re-teaching are proposed as key aspects of future research and development.     

Understanding individual differences in word recognition skills of ESL children

This paper focuses on the extent to which the development of ESL (English as a Second Language) word recognition skills mimics similar trajectories in same-aged EL1 (English as a First Language) children, and the extent to which phonological processing skills and rapid naming can be used to predict word recognition performance in ESL children. Two cohorts of Grade 1 ESL and EL1 primary-level children were followed for two consecutive years. Results indicated that vocabulary knowledge, a measure of language proficiency, and nonverbal intelligence were not significant predictors of word recognition in either group. Yet, by considering individual differences in phonological awareness and rapid naming, it was possible to predict substantial amounts of variance on word recognition performance six months and one year later in both language groups. Commonality analyses indicated that phonological awareness and rapid naming contributed unique variance to word recognition performance. Moreover, the profiles of not at-risk children in the EL1 and ESL groups were similar on all but the oral language measure, where EL1 children had the advantage. In addition, EL1 and ESL profiles of children who had word-recognition difficulty were similar, with low performance on rapid naming and phonological awareness. Results indicate that these measures are reliable indicators of potential reading disability among ESL children.     

Examining the linguistic coding differences hypothesis to explain individual differences in foreign language learning

In this paper, it is suggested that foreign language learning problems result from difficulties with native language learning and hypothesized that difficulties with phonological processing may be the locus of foreign language learning difficulties for some poor foreign language learners. Evidence is described that supports these positions. It is argued that conceptualizing foreign language learning problems as alanguage problem allows researchers to more clearly specify deficits related to the learning of a foreign language. Research evidence which shows that good and poor foreign language learners exhibit significantly different levels of native language skill and phonological processing is summarized. Finally, potential challenges to my hypotheses as an explanation for foreign language learning problems are reviewed.
