Cognitive precursors of reading : A cross-linguistic perspective
In this paper, we survey current evidence on cognitive precursors of reading in different orthographies by reviewing studies with a cross-linguistic research design. Graphic symbol knowledge, phonological awareness, morphological awareness, and rapid automatized naming were found to be associated with reading acquisition in all orthographies investigated. However, apart from rapid naming, this association is mostly interactive, meaning that young children develop their symbol knowledge, and phonological and morphological awareness during reading development. Especially for phonological awareness, cross-linguistic evidence involving phonologically transparent orthographies, both alphabetic and non-alphabetic, suggests that it may be less of a hurdle than in the complex English orthography. Cross-linguistic research designs can be a useful methodological approach to test limits of reading theories that were initially developed for alphabetic orthographies
Acquisition of orthographic forms via complex spoken word training
This study used a novel word-training paradigm to examine the integration of spoken word knowledge when learning to read morphologically complex novel words. Australian primary school children including Grades 3–5 were taught the oral form of a set of novel morphologically complex words (e.g., (/vɪbɪŋ/, /vɪbd/, /vɪbz/), with a second set serving as untrained items. Following oral training, participants saw the printed form of the novel word stems for the first time (e.g., vib), embedded in sentences, while their eye movements were monitored. Half of the stems were spelled predictably and half were spelled unpredictably. Reading times were shorter for orally trained stems with predictable than unpredictable spellings and this difference was greater for trained than untrained items. These findings suggest that children were able to form robust orthographic expectations of the embedded morphemic stems during spoken word learning, which may have occurred automatically without any explicit control of the applied mappings, despite still being in the early stages of reading development. Following the sentence reading task, children completed a reading-aloud task where they were exposed to the novel orthographic forms for a second time. The findings are discussed in the context of theories of reading acquisition
Variations in the use of simple and context-sensitive grapheme-phoneme correspondences in English and German developing readers
Learning to read in most alphabetic orthographies requires not only the acquisition of simple grapheme-phoneme correspondences (GPCs) but also the acquisition of context-sensitive GPCs, where surrounding letters change a grapheme’s pronunciation. We aimed to explore the use and development of simple GPCs (e.g. a ➔ /æ/) and context-sensitive GPCs (e.g. [w]a ➔ /ɔ/, as in “swan” or a[l][d] ➔ /o:/, as in “bald”) in pseudoword reading. Across three experiments, English- and German-speaking children in grades 2–4 read aloud pseudowords, where vowel graphemes had different pronunciations according to different contexts (e.g. “hact”, “wact”, “hald”). First, we found that children use context-sensitive GPCs from grade 2 onwards, even when they are not explicitly taught. Second, we used a mathematical optimisation procedure to assess whether children’s vowel responses can be described by assuming that they rely on a mix of simple and context-sensitive GPCs. While the approach works well for German adults (Schmalz et al. in Journal of Cognitive Psychology, 26, 831–852, 2014), we found poor model fits for both German- and English-speaking children. Additional analyses using an entropy measure and data from a third experiment showed that children’s pseudoword reading responses are variable and likely affected by random noise. We found a decrease in entropy across grade and reading ability across all conditions in both languages. This suggests that GPC knowledge becomes increasingly refined across grades 2–4
Eye movements during reading
Written words are everywhere. Learning to read is one of the main tasks of our early school years, and the ability to read opens up a world of possibilities—we can absorb ourselves in stories, remind ourselves of important information, and learn new things. But few of us think about what we are actually doing as we read. Moving the eyes is essential for reading. For instance, to read this sentence, you probably began by looking at the first word before moving your eyes to each word in turn. All the while, you are working hard to recognize and understand each word. In this article, you will learn about why eye movements are a necessary part of reading, how they are measured, what they tell scientists about what is happening in the mind during reading, and how they change as children grow into adults
Sleep promotes the emergence of lexical competition in visual word recognition
Lexical competition processes are widely viewed as the hallmark of visual word recognition, but little is known about the factors that promote their emergence. This study examined for the first time whether sleep may play a role in inducing these effects. A group of 27 participants learned novel written words, such as banara, at 8 am and were tested on their learning at 8 pm the same day (AM group), while 29 participants learned the words at 8 pm and were tested at 8 am the following day (PM group). Both groups were retested after 24 hours. Using a semantic categorisation task, we showed that lexical competition effects, as indexed by slowed responses to existing neighbor words such as banana, emerged 12 hours later in the PM group who have had slept after learning but not in the AM group. After 24 hours the competition effects were evident in both groups. These findings have important implications for theories of orthographic learning and broader neurobiological models of memory consolidation
Phonics training for English-speaking poor readers (Review)
Background
The reading skills of 16% of children fall below the mean range for their age, and 5% of children have significant and severe reading problems. Phonics training is one of the most common reading treatments used with poor readers, particularly children.
Objectives
To measure the effect of phonics training and explore the impact of various factors, such as training duration and training group size, that might moderate the effect of phonics training on literacy‐related skills in English‐speaking poor readers.
Search methods
We searched CENTRAL, MEDLINE, Embase, 12 other databases, and three trials registers up to May 2018. We also searched reference lists of included studies and contacted experts in the field to identify additional studies.
Selection criteria
We included studies that used randomisation, quasi‐randomisation, or minimisation to allocate participants to a phonics intervention group (phonics training only or phonics training plus one other literacy‐related skill) or a control group (no training or non‐literacy training). Participants were English‐speaking poor readers with word reading one standard deviation below the appropriate level for their age (children, adolescents, and adults) or one grade or year below the appropriate level (children only), for no known reason. Participants had no known comorbid developmental disorder, or physical, neurological, or emotional problem.
Data collection and analysis
We used standard methodological procedures expected by Cochrane.
Main results
We included 14 studies with 923 participants in this review. Studies took place in Australia, Canada, the UK, and the USA. Six of the 14 included studies were funded by government agencies and one was funded by a university grant. The rest were funded by charitable foundations or trusts. Each study compared phonics training alone, or in conjunction with one other reading‐related skill, to either no training (i.e. treatment as usual) or alterative training (e.g. maths). Participants were English‐speaking children or adolescents, of low and middle socioeconomic status, whose reading was one year, one grade, or one standard deviation below the level expected for their age or grade for no known reason. Phonics training varied between studies in intensity (up to four hours per week), duration (up to seven months), training group size (individual and small groups), and delivery (human and computer). We measured the effect of phonics training on seven primary outcomes (mixed/regular word reading accuracy, non‐word reading accuracy, irregular word reading accuracy, mixed/regular word reading fluency, non‐word reading fluency, reading comprehension, and spelling). We judged all studies to be at low risk of bias for most risk criteria, and used the GRADE approach to assess the quality of the evidence.
There was low‐quality evidence that phonics training may have improved poor readers' accuracy for reading real and novel words that follow the letter‐sound rules (standardised mean difference (SMD) 0.51, 95% confidence interval (CI) 0.13 to 0.90; 11 studies, 701 participants), and their accuracy for reading words that did not follow these rules (SMD 0.67, 95% CI 0.26 to 1.07; 10 studies, 682 participants). There was moderate‐quality evidence that phonics training probably improved English‐speaking poor readers' fluency for reading words that followed the letter‐sounds rules (SMD 0.45, 95% CI 0.19 to 0.72; 4 studies, 224 participants), and non‐word reading fluency (SMD 0.39, 95% CI 0.10 to 0.68; 3 studies, 188 participants), as well as their accuracy for reading words that did not follow these rules (SMD 0.84, 95% CI 0.30 to 1.39; 4 studies, 294 participants). In addition, there was low‐quality evidence that phonics training may have improved poor readers' spelling (SMD 0.47, 95% CI –0.07 to 1.01; 3 studies, 158 participants), but only slightly improve their reading comprehension (SMD 0.28, 95% CI –0.07 to 0.62; 5 studies, 343 participants).
Authors' conclusions
Phonics training appears to be effective for improving literacy‐related skills, particularly reading fluency of words and non‐words, and accuracy of reading irregular words. More studies are needed to improve the precision of outcomes, including word and non‐word reading accuracy, reading comprehension, spelling, letter‐sound knowledge, and phonological output. More data are also needed to determine if phonics training in English‐speaking poor readers is moderated by factors such as training type, intensity, duration, group size, or administrator
An experimental comparison of additional training in phoneme awareness, letter-sound knowledge and decoding for struggling beginner readers
Background Despite evidence that synthetic phonics teaching has increased reading attainments, a sizable minority of children struggle to acquire phonics skills and teachers lack clear principles for deciding what types of additional support are most beneficial. Synthetic phonics teaches children to read using a decoding strategy to translate letters into sounds and blend them (e.g., c-a-t = “k - æ – t” = “cat”). To use a decoding strategy, children require letter-sound knowledge (LSK) and the ability to blend sound units (phonological awareness; PA). Training on PA has been shown to benefit struggling beginning readers. However, teachers in English primary schools do not routinely check PA. Instead, struggling beginner readers usually receive additional LSK support. Aims Until now, there has been no systematic comparison of the effectiveness of training on each component of the decoding process. Should additional support for struggling readers focus on improving PA, or on supplementary LSK and/or decoding instruction? We aim to increase understanding of the roles of LSK and PA in children's acquisition of phonics skills and uncover which types of additional training are most likely to be effective for struggling beginner readers. Sample and Method We will compare training on each of these components, using a carefully controlled experimental design. We will identify reception-age children at risk of reading difficulties (target n = 225) and randomly allocate them to either PA, LSK or decoding (DEC) training. We will test whether training type influences post-test performance on word reading and whether any effects depend on participants' pre-test PA and/or LSK. Results and Conclusions Two hundred and twenty-two participants completed the training. Planned analyses showed no effects of condition on word reading. However, exploratory analyses indicated that the advantage of trained over untrained words was significantly greater for the PA and DEC conditions. There was also a significantly greater improvement in PA for the DEC condition. Overall, our findings suggest a potential advantage of training that includes blending skills, particularly when decoding words that had been included in training. Future research is needed to develop a programme of training on blending skills combined with direct vocabulary instruction for struggling beginner readers
Does phonological overlap of cognate words modulate cognate acquisition and processing in developing and skilled readers?
Very few studies exist on the role of cross-language similarities in cognate word
acquisition. Here we sought to explore, for the first time, the interplay of orthography (O) and
phonology (P) during the early stages of cognate word acquisition, looking at children and
adults with the same level of foreign language proficiency, and by using two variants of the
word-association learning paradigm (auditory learning method vs. auditory + written method).
Eighty participants (forty children and forty adults, native speakers of European Portuguese
[EP]), learned a set of EP-Catalan cognate words and non-cognate words. Among the cognate
words, the degree of orthographic and phonological similarity was manipulated. Half of the
children and adult participants learned the new words via an L2 auditory and written-L1 word
association method, while the other half learned the same words only through an L2 auditoryL1
word association method. Both groups were tested in an auditory recognition task and a
go/no-go lexical decision task. Results revealed a disadvantage for children in comparison to
adults, which was reduced in the auditory learning method. Furthermore, there was an
advantage for cognates relative to non-cognates regardless of the age of participants.
Importantly, there were modulations in cognate word processing as a function of the degree of
O and P overlap which were restricted to children. The findings are discussed in light of the
most relevant bilingual models of word recognition.This research was conducted at the Psychology Research Centre (UID/PSI/01662/2013),

Reading Text Increases Binocular Disparity in Dyslexic Children
Children with developmental dyslexia show reading impairment compared to their peers, despite being matched on IQ, socio-economic background, and educational opportunities. The neurological and cognitive basis of dyslexia remains a highly debated topic. Proponents of the magnocellular theory, which postulates abnormalities in the M-stream of the visual pathway cause developmental dyslexia, claim that children with dyslexia have deficient binocular coordination, and this is the underlying cause of developmental dyslexia. We measured binocular coordination during reading and a non-linguistic scanning task in three participant groups: adults, typically developing children, and children with dyslexia. A significant increase in fixation disparity was observed for dyslexic children solely when reading. Our study casts serious doubts on the claims of the magnocellular theory. The exclusivity of increased fixation disparity in dyslexics during reading might be a result of the allocation of inadequate attentional and/or cognitive resources to the reading process, or suboptimal linguistic processing per se
