Poor readers have lower academic achievement and increased anxiety, including reading anxiety, which may perpetuate lower academic achievement. We explored reading anxiety in university students, investigating whether the association between reading ability and academic achievement is mediated by reading anxiety (independent of general anxiety). Participants were students (n = 169, 69% female, age = 20.70) at an Australian university who completed an online reading assessment (decoding skills, phonological awareness, orthographical knowledge and comprehension), and a survey examining reading anxiety, trait anxiety and self-reported reading history. Academic achievement was based on university grades. Two reading anxiety factors (social and non-social) were identified; both factors were distinct from trait anxiety. Reading ability was negatively correlated with reading anxiety and positively correlated with academic achievement. Reading anxiety was not correlated with academic achievement and it did not mediate the relationship between reading ability and academic achievement as expected. As this was the first study to explore reading anxiety in adults, further research is required to determine the impact reading anxiety may have on university students beyond academic achievement.

Research has shown that children with dyslexia and children with a low socioeconomic status (SES) fall behind in terms of literacy acquisition, but a question remains regarding the cumulative effect of dyslexia and SES on linguistic, cognitive and reading skills. To examine the impact of cognition and environment on literacy development, we returned to the data set of 1,441 elementary school children (223 dyslexic readers and 1,241 typical readers) from low and medium-high SES backgrounds within Palestinian society in Israel who had participated in the development study of a comprehensive battery of tests in oral and written Arabic. The findings of this retrospective study reveal that, across grade levels, dyslexic readers from a low SES background showed similar performance to those from a medium-high SES background on most linguistic, cognitive and reading measures. As for typical readers, SES contributed to individual differences in all linguistic, cognitive and reading indices, with the exception of RAN. Finally, a cumulative effect of dyslexia and SES was found in relation to morphology, vocabulary, listening comprehension and text-reading accuracy.

Perceiving and producing English phonemic vowel length contrasts is challenging for non-native speakers. According to multi-time resolution models, endogenous slow/fast rhythms contribute, respectively, in the right/left hemispheres, to long/short acoustic cue processing. This study introduced a perceptual training method implementing dichotic stimulation to improve /i:/-/ɪ/ processing by promoting hemispheric complementarity. Twenty non-dyslexic and 20 dyslexic French adults received 1 hr-training over 3 days. Productions were evaluated with pre-/post-tests. Training enhanced vowel duration contrast in word production by /i:/ lengthening and /ɪ/ shortening in both groups. Adults with dyslexia compensated fewer /i:/ lengthening by /ɪ/ shortening than did non-dyslexic adults. Transfer from perceptual training to production seems possible for foreign-language learning even in dyslexic adults. The extent to which dichotic presentation contributed to training effectiveness cannot be evaluated here, but the triggering of lengthening and shortening mechanisms suggests that lateralized complementary skills have been enhanced by dichotic stimulation.

The goal of this paper is to observe revision during handwritten text production of French students with and without dyslexia. Subjects with typical language development automate spelling during childhood and adolescence, progressively with experience, this enables them—according to capacity theory applied to written text production (McCutchen, Educational Psychology Review, 8, 1996, 299)—to allocate more cognitive resources to higher-level processes (Bereiter & Scardamalia, The psychology of written composition. Hillsdale: Lawrence Erlbaum, 1987). A lack of automation in spelling could result in poor compositional performance (Fayol & Miret, Psychologie Française, 50, 2005, 391). Moreover, Morken and Helland (Dyslexia, 19, 2013, 131) have shown that young children with dyslexia, engaged in a sentence dictation task, revise their text as much as control children, however their revisions are of lower quality. If students with dyslexia have not totally automated spelling (Mazur-Palandre, Développements (Revue Interdisciplinaire du développement Cognitif Normal et Pathologique), 18, 2016, 177), what is the impact on higher-level processes, such as revision? Our goal is to examine if students with dyslexia and control students proofread their texts in the same way. Results show that they display some similarity but students with dyslexia seem to have a deficit in the error detection mechanism (Horowitz & Breznitz, International Journal of Disability, Development and Education, 58, 2011, 33) and revisions are less efficient. We discuss these results by considering previous studies we conducted on spelling, speech and neuropsychological assessments of our dyslexic participants.

Expository paragraph writing is difficult to learn and teach. For many students, particularly those with learning disabilities, it is difficult to manage the multiple, simultaneous complex processes required for success. And for their teachers, writing is the content area in which they feel least prepared to teach. This intervention applied the concept of reverse engineering to instructional design to teach expository paragraph writing using a color-cued graphic organizer. The study evaluated the effects of using a systematic color code to highlight the alignment of where ideas originate in a graphic organizer to their development into a sentence within a well-organized expository paragraph. Using a single case research design, with a pre- and post-intervention assessments, students (n = 5) with dyslexia improved their expository paragraph knowledge and skills. Percentage of non-overlapping data and Tau analyses indicate a large to very large effect of the 2-week intervention. Results, suggestions for further research, and implications for practice are discussed.

Reading and spelling skills are important to communicate in today's literate society, however, the underlying processes of spelling skills are under-researched compared to reading skills. Our goals were to (a) study how the component skills of phonological, orthographic and morphological awareness are different in adults with and without reading difficulties, and (b) characterize the relationship between the component skills and reading and spelling performance in both skilled and poor readers. Participants (N = 37, N = 15 with reading impairments and N = 22 skilled readers) took part in the study where they completed several literacy-based measures. We performed a series of mixed ANOVAs to study the between-group differences in performance and the relationship between different literacy outcomes, respectively. We found evidence for poor phonological and morphological awareness in the poor readers compared to the skilled readers. We also found differential relationships between the component skills and reading and spelling behavior. Specifically, sound awareness was significantly related to reading and spelling measures in the skilled readers, whereas morphological and sound awareness played an important role in the same skills in the poor readers. We discuss these findings in the context of potential remediation strategies for adults with persistent literacy impairments.

Accelerated reader (AR) is a computerized reading program commonly used in schools. The program aims to enhance students' reading achievement and encourage students to read more through goal setting and frequent reading practice. A meta-analytic review of the AR was conducted to analyse its effectiveness as an evidence-based intervention for improving student reading achievement, attitude, and motivation. This study investigated potential moderating variables, including publication type, participant, and study characteristics that impact student reading outcomes. A total of 44 studies from peer-reviewed journal articles and dissertations met the inclusion criteria. Participants included 16,653 students enrolled in elementary, middle, and high school. Hedges' g effect sizes measures suggest pretest–posttest one-group AR studies have moderate effects (g = 0.541) while comparison group AR studies have marginal effects (g = 0.278). A meta-regression model of six potential categorical moderators of comparison group studies indicted no significant moderators. Implications and the need for further research regarding evidence-based and culturally appropriate reading interventions are discussed.

Children with dyslexia, compared with typically reading peers, are at increased risk of internalising (e.g., anxiety) and externalising (e.g., aggression) mental health concerns; why this is the case is largely unknown. Our aim was to explore the socio-emotional experience of growing up with dyslexia from both child and parent perspectives. In so doing, we aimed to gain a better understanding of self-esteem and mental health in the context of dyslexia. One-to-one semi-structured interviews with 17 children with reading difficulties (aged 9–14 years; 16 with a diagnosis of dyslexia) and their mothers (interviewed separately) were analysed using Braun and Clarke's reflexive thematic analysis approach with a neurodiversity lens. We developed three themes to address the research aim: (1) Different in a good/bad way; (2) Exhausted and overwhelmed; and (3) It takes a community: Family school connections. Children discussed having “worries” and experiencing school-related stress and embarrassment. Mothers perceived children's internalising and externalising behaviour (meltdowns), school refusal, and homework resistance as emotional responses to children's school struggles due to poor “person-environment fit.” Our analysis highlights the particular importance of parent support, friendship, and school-connectedness for the wellbeing of children with dyslexia.

In many countries, intervention costs are not covered by public health care. A critical basis for deciding whether an intervention is covered or not is to analyse the relation between benefits and costs of the intervention, and to quantify the consequential costs. In this study, a cost-utility analysis was computed to investigate the costs of individualized dyslexia intervention while quantifying the benefit in terms of health-related quality of life in a sample of 36 individuals with dyslexia. In addition, educational outcomes and costs of untreated dyslexia for the society were estimated using information for class repetition, school success, and unemployment rates from previous studies and official statistics. A significant increase in quality of life with medium effect sizes was found across all quality-of-life measures. Increases in quality of life were domain-specific, thus occurring specifically in those domains that are affected by learning disorders. The cost-utility ratio was 9,782 Euros per quality adjusted life years (QALYs), which is in line with similar therapy forms, such as speech therapy. The loss of productivity for untreated dyslexia in the German population was estimated for class repetition and reduced income due to lower school degrees. The cost-utility analysis and the calculation of consequential costs suggest that the dyslexia intervention is cost-effective.
