Irlen lenses & adults a small scale study of reading speed,accuracy, comprehension & self‐image

Abstract

This study investigated the effects of using Irlen coloured filters on reading speed, accuracy, comprehension and self‐image over 6 months of use. Three study groups were used (immediate lens use, delayed lens use and control), involving 33 subjects ranging in age from 18 years to 62 years. The experimental groups demonstrated significant improvements in reading accuracy and comprehension over the 6 months of the study, although there was a plateau effect for the second half of the 6 month study period. The experimental and control groups also improved significantly on scores of self‐esteem over the 6 months. It is suggested that the reported reduction in print and background distortions may allow attention to be directed to the processing of continuous text rather than to the identification of individual words, although improvement will be restricted if basic word attack skills ore not fully mastered.     

The effectiveness of Irlen filters for improving reading performance: a pilot study

The objectives of this pilot study were to investigate the effectiveness of Irlen filters for improving comfort and reading performance and to determine whether traditional optometric intervention would be effective in relieving the symptoms commonly reported by people seeking help through the use of Irlen filters. Thirty subjects were included in the study: 12 males and 18 females. The ages of the subjects ranged from 9 to 51 (mean = 23.6). They were randomly placed in either an Irlen filter treatment group (n = 11), a vision therapy treatment group (n = 11), or a control group (n = 8). Pre- and posttesting on all subjects included a vision evaluation, reading and intelligence testing, the Irlen scotopic sensitivity screening test, and a symptom questionnaire. Results revealed that subjects in both treatment groups were more comfortable after treatment, although only the vision therapy group showed improvement in vision functioning. The subjects in the Irlen filter group did not show any significant gains in reading rate, word recognition in context, or comprehension.     

Questioning the benefits that coloured overlays can have for reading in students with and without dyslexia

Visual stress (the experience of visual distortions and discomfort during prolonged reading) is frequently identified and alleviated with coloured overlays or lenses. Previous studies have associated visual stress with dyslexia and as a consequence, coloured overlays are widely distributed to children and adults with reading difficulty. However, this practice remains controversial. We investigated whether overlays have advantageous and reliable benefits for reading in undergraduate students with and without dyslexia. Both groups read jumbled text faster with a coloured overlay than without. The dyslexic group did not show greater gains than controls, despite reporting significantly more symptoms of visual stress. However, coloured overlays did not improve reading rate or comprehension of connected text. The improvement in reading speed with an overlay was not reliable and was significantly reduced at retesting for dyslexic students. These results question the value of coloured overlays as a tool for identifying visual stress and as a form of remediation for the reading difficulties associated with dyslexia.     

The effects of Irlen colored lenses on students' specific reading skills and their perception of ability: a 12-month validity study

Recent evidence suggests that a specific visual-perceptual dysfunction not normally assessed by eye examination should be considered as a significant cause of reading problems. The use of tinted nonoptical (Irlen) lenses to minimize this dysfunction has been hypothesized to result in significant improvement in reading and other visual-processing skills. The present study involved 44 subjects with reading disabilities (33 males, 11 females), aged between 9 years 1 month and 15 years 11 months, who had been provided with Irlen lenses. Assessment of subjects' perception of their own ability (Student's Perception of Ability Scale) 6 and 12 months after the fitting of Irlen lenses indicated a significant improvement in attitude to school and to basic academic skills. Subjects also demonstrated significant improvements in reading comprehension and reading accuracy, but not in rate of reading, when assessed using the Neale Analysis of Reading Ability at 3-, 6-, and 12-month intervals after lens fitting. Differences in the pattern of improvement are discussed in light of previous findings.     

The Use of Coloured Overlays to Improve Visual Processing ‐ A Preliminary Survey

Forty volunteers reporting consistent reading problems were divided into three groups on the basis of an assessment of degree of scotopic sensitivity. Four speeded visual processing tasks involving word matching and letter and number identification were administered to all subjects using three plastic overlays, one of a colour maximizing visual efficiency, one chosen at random and one with no colour. For subjects with high scotopic sensitivity, the use of optimal coloured overlays yielded significantly better results on some visual tasks than the other two overlays. Implications of these findings are discussed.     

Reading disabilities and the effects of colored filters

The efficacy of a controversial treatment, using colored filters to remediate reading disabilities, was measured empirically, with colored overlays placed over reading material on white paper. Irlen's (1983) method is to prescribe specific tinted filters as lenses that she claims filter specific light frequencies and remove a range of perceptual disorders that adversely affect reading and related learning performance. Irlen calls this condition "scotopic sensitivity" and claims it is a significant factor in a high percentage of people with learning disabilities. Ninety-two children with significant reading disabilities were classified as either scotopic or nonscotopic using the Irlen Differential Perceptual Schedule, and were randomly assigned to one of six treatment groups using colored or clear overlays. Reading performance (rate, accuracy, and comprehension) as measured by the Neale Analysis of Reading Ability (Neale, 1987) and the Formal Reading Inventory (Wiederholt, 1986) improved significantly when the scotopic children read with the preferred colored overlay filter compared to clear or different-colored overlay filters. Nonscotopic children showed no change.     

The Relation Between Morphological Awareness and Reading Comprehension: Evidence From Mediation and Longitudinal Models

We examined the role of a hypothesized factor in reading comprehension: morphological awareness, or the awareness of and ability to manipulate the smallest meaningful units or morphemes. In this longitudinal study, we measured English-speaking children’s morphological awareness, word reading skills, and reading comprehension at Grades 3 and 4, in addition to their phonological awareness, vocabulary, and nonverbal ability as control measures. Path analyses revealed that word reading skills partially mediated the relationship between morphological awareness and reading comprehension at each grade. Further, children’s early morphological awareness partially explained children’s gains in reading comprehension, and their early reading comprehension partially explained their gains in morphological awareness. These findings support the predictions of recent models of reading comprehension: that morphological awareness impacts reading comprehension both indirectly through word reading skills and directly through the language system and that morphological awareness underpins the development of reading comprehension (e.g., Perfetti, Landi, & Oakhill, 2005).     

Irlen Colored Filters in the Classroom: A 1‐Year Follow‐Up

Colored filters are used to treat Irlen syndrome (IS), a controversial disorder posited to be the cause of a substantial proportion of reading difficulties. Previously, we found that Irlen colored filters do not produce any short‐term alleviation of reading difficulties in schoolchildren aged 7–12. Here, we tested whether colored filters show benefits with longer‐term use, in a subset of the original sample. We measured reading rate with and without filters in 18 children diagnosed with IS, who had been using the filters for 1 year, and compared the progression of their reading ability across the year against 10 poor‐reader control children. The Irlen‐treatment group did not read any faster when using their colored filter, and showed no disproportionate gain in reading progress across the year compared to controls. We conclude that Irlen filters do not benefit reading, even after 1 year of use.     

Preventing a summer slide in reading – the effects of a summer school

ABSTRACT

Researchers have found that summer reading loss contributes to the reading achievement gap between low and high socioeconomic (SES) children. This study aimed to examine the effectiveness of a 3-week summer intervention in addressing this slide for 36 low SES children compared with another 36 children in a matched control group from one New Zealand school. The program involved one-to-one tutoring with explicit phonics instruction, high-frequency word-reading practice and application of these skills in reading age-appropriate texts. Results showed that although the mean reading comprehension slide was 5.8 months for both groups, the summer school group had higher word reading scores than the control group. The summer school participants showed improvements in phonological recoding ability, word reading, spelling and passage reading accuracy. These were not sufficient to stop the reading comprehension slide, but the program did make inroads. With further emphasis on comprehension strategies, the achievement gap may narrow.     

Minding morphology: How morphological awareness relates to reading for English language learners

This study explored subprocesses of reading for 157 fifth grade Spanish-speaking English language learners (ELLs) by examining whether morphological awareness made a unique contribution to reading comprehension beyond a strong covariate-phonological decoding. The role of word reading and reading vocabulary as mediators of this relationship was also explored. Results showed that fourth grade morphological awareness did not make a significant unique direct effect on fifth grade reading comprehension, controlling for phonological decoding, word reading, and reading vocabulary. Fourth grade morphological awareness did, though, make a unique moderate total contribution to fifth grade reading comprehension with reading vocabulary, but not word reading, mediating the relationship when controlling for phonological decoding. In contrast, phonological decoding made a nonsignificant total contribution to reading comprehension with neither word reading nor reading vocabulary mediating the relationship when controlling for morphological awareness. Alternative models were also explored, showing the importance of including both predictors in a model of ELL reading comprehension, primarily to include the support of phonological decoding to word reading and the support of morphological awareness to reading comprehension via reading vocabulary. Results highlighted the importance of morphological awareness in facilitating reading comprehension via improving reading vocabulary knowledge, and also the potential of interventions involving morphological instruction to support reading achievement for Spanish-speaking ELLs.     

The Effects of One versus Two Years of Intensive Reading Intervention Implemented with Late Elementary Struggling Readers

We examined the effectiveness of a researcher‐provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business‐as‐usual comparison condition (BAU). Students assigned to two years of intervention demonstrated significantly greater gains in reading fluency compared to students who received one year of intervention and the BAU group. Students in both the one‐ and two‐year groups demonstrated similar and significantly larger gains in word reading in comparison to the BAU group. There were no statistically significant differences between the three groups on standardized measures of reading comprehension. We discuss these results in the context of research with late elementary and secondary students targeting reading comprehension.     

Multisensory programs in the public schools: A brighter future for LD children

A longitudinal study followed the progress of a group of elementary SLD students as they were instructed using the Alphabetic Phonics (AP) curriculum. After a three year period, the AP curriculum produced positive results in reading comprehension for most SLD students, particularly those who began the program in first and second grade. Students in resource and self-contained settings made significant gains in reading comprehension, although the two types of students exhibited different patterns of progress. Students of different ability levels responded differently to the AP curriculum. Average and above average students made significant progress in reading comprehension, but below average students did not advance substantially in relation to their ability level. At the end of three years, classroom teachers had a significantly more positive view of students’ word attack, oral reading, and silent reading comprehension skills.     

Children's reading profiles on exiting the Reading Recovery programme: do they predict sustained progress?

The aim of this study was to identify reading profiles, which predict the literacy progress of Reading Recovery graduates. Reading Recovery is an intensive remediation for children after the first year of school. Children were assessed at exit from the programme and at 3‐month, 6‐month and 12‐month follow‐up points. Text Reading Level made unique contributions to word reading, spelling and writing at all time points and was consistently the best predictor of word reading. Phonological processing also made unique contributions to word reading and spelling. Reading comprehension was found to be the best predictor of National Curriculum sublevels for reading and writing, 12 months later. These findings indicate that levelled texts, as employed in Reading Recovery, provide a good indication of progress in word reading, spelling and writing after the programme has been discontinued, but also present a case for assessing other reading skills (e.g., phonological processing and reading comprehension) in order to help predict sustained progress in literacy.     

The effect of school entrance age on academic achievement and social-emotional adjustment of children: Follow-up study of fourth graders

One hundred and thirty-seven fourth-grade pupils participated in a follow-up study of the effect of school-entrance age on academic achievement and social-emotional functioning. The sample included 73 oldest pupils, born in the months of January to March, and 64 youngest pupils, born in October to December of the same calendar year. Results indicated that differences between the two groups in academic and social-emotional measures, found when the subjects were in first grade, persisted in part to the fourth grade. The youngest subjects continued to score lowest in mathematics and in oral and silent reading comprehension; they were slower readers; and they had higher trait anxiety scores. In addition, the differences between the groups in oral and silent reading comprehension performance were found to increase over the years.     

The relationship between motivation to read and reading comprehension in chilean elementary students

This study examined the role of reading motivation in reading comprehension achievement of 1070 Chilean third, fourth, and fifth-grade students enrolled in public and private schools. Students were assessed in Spanish reading comprehension and were administered the Motivation to Read Profile from Gambrell, Palmer, Codling and Mazzoni (1996), at the beginning and end of the school year. Results showed that motivation to read at the beginning of the school year was significantly associated with gains in reading comprehension skills. When disaggregating motivation into self-concept and value of reading, only self-concept of reading significantly predicted gains in reading comprehension. Moderation analyses showed that students that started the year with lower reading comprehension and higher motivation to read, had significantly better reading comprehension at the end of the school year, than their peers who started with lower reading motivation. The pedagogical implications are discussed.

     

An observation study of reading instruction provided to elementary students with learning disabilities in the resource room

This study documents the amount and quality of reading instruction provided to second‐ through fifth‐grade students with learning disabilities provided resource‐room services. Reading instruction provided by 10 special education resource‐room teachers was observed. Findings reveal that teachers and students were on task during instructional time that included phonological awareness, word study, comprehension, reading fluency, and vocabulary instruction of average to high average quality. Although class size was small overall, whole‐group instructional delivery was most common. Students made statistically significant gains in oral reading fluency but did not increase their standard scores on measures of comprehension or word reading. © 2010 Wiley Periodicals, Inc.     

Reading achievement, metacognition, reading self-concept and interest: A study of German students in grades 3 and 4

This study examined the reading achievement, metacognitive knowledge related to reading and memory, reading self-concept, and interest in reading of 140 German school students in Grades 3 and 4. The results indicated significant correlations between the metacognitive variables, motivational variables, and amongst metacognitive and motivational variables, as well as with reading achievement variables. The examination of good and poor readers showed significant differences in metacognitive knowledge of reading and memory, reading self-concept, interest in reading, and in teacher judgements of reading achievement between the groups. Differences between Grade 3 and 4 students were found in their word decoding skills, metacognitive knowledge about reading and memory, and teacher judgements of reading achievement. Results of the regression analysis indicated that reading achievement was predicted by grade level, word decoding, and teacher evaluations of reading achievement. The causal modelling indicated that motivation and metacognition affect reading comprehension in different ways. The findings are discussed in terms of future research and their educational implications.     

Language abilities, reading acquisition, and developmental dyslexia: a discussion of hypothetical and observed relationships.

Tests of a model of the expected relationships between language abilities and reading achievement measures from the beginning of kindergarten through third grade are discussed. At kindergarten, more global language abilities influenced early, wholistic measures of reading achievement, including letter and number naming. At Grade 1, these earlier accomplishments had a direct effect on word recognition, but a second direct effect was also apparent for word and pheneme segmentation measured in kindergarten. Comprehension at Grade 1 was influenced primarily by word recognition abilities at the same time. At Grade 2, comprehension influenced word recognition; at Grade 3, word recognition and comprehension were essentially independent. These findings are considered in the context of Frith's three-phase hypothesis of reading acquisition. A rationale for testing the potential of training in auditory segmentation to modulate the effects of developmental dyslexia is presented.     

Parental involvement in the development of children's reading skill: a five-year longitudinal study

This article presents the findings of the final phase of a 5-year longitudinal study with 168 middle- and upper middle-class children in which the complex relations among early home literacy experiences, subsequent receptive language and emergent literacy skills, and reading achievement were examined. Results showed that children's exposure to books was related to the development of vocabulary and listening comprehension skills, and that these language skills were directly related to children's reading in grade 3. In contrast, parent involvement in teaching children about reading and writing words was related to the development of early literacy skills. Early literacy skills directly predicted word reading at the end of grade 1 and indirectly predicted reading in grade 3. Word reading at the end of grade 1 predicted reading comprehension in grade 3. Thus, the various pathways that lead to fluent reading have their roots in different aspects of children's early experiences.     

The effects of dyad reading and text difficulty on third-graders’ reading achievement

This study replicated, with modifications, previous research of dyad reading using texts at various levels of difficulty (Morgan, 1997). The current project measured the effects of using above–grade-level texts on reading achievement and sought to determine the influences of dyad reading on both lead and assisted readers. Results indicate that weaker readers, using texts at two, three, and four grade levels above their instructional levels with the assistance of lead readers, outscored both proficient and less proficient students in the control group across multiple measures of reading achievement. However, the gains made by assisted readers were not significantly different relative to the various text levels. When all assessments were considered, assisted readers reading texts two grade levels above their instructional levels showed the most robust gains in oral reading fluency and comprehension. Lead readers also benefited from dyad reading and continued their respective reading developmental trajectories across measures.
