[A new reading chart for simultaneous determination of reading vision and reading speed].

BACKGROUND: Reading acuity as well as reading speed are good predictors of everyday visual function. As visual acuity tests are poor predictors of the real-world function, performance-based tests, e.g., reading speed measurements, can be used for the determination of visual function. Thus, a German reading chart was developed in order to evaluate reading acuity as well as reading speed. METHODS: Print size is defined as the height of a lower case x and progresses logarithmically from one phrase to another (factor: 1.25). Reading acuity is determined in LogRAD (Reading Acuity Determination). 32 short German phrases were created, comparable concerning grammatical difficulty as well as in number (n = 14), length and position of words. The reading speed parameters measured with a stop-watch in 160 persons (aged: Phi = 21a +/- 3.8a) were calculated in words per minute (w/min). Out of the 32 phrases the 24 most similar ones were selected statistically and used for the reading charts (Radner Reading Charts). With these reading charts a reading acuity score (LogRAD-score) can be calculated considering reading errors in words of different length. Reading speed can be determined at the same time. Reading acuity (LogRAD-Score) was measured in 32 normal eyes of 16 students and compared to the angular visual acuity (LogMAR). RESULTS: The mean reading speed of the test persons was 211.8 +/- 34.1 w/min. 24 phrases fulfilled the test item criteria for the reading chart: mean +/- 0.25 x SD. The reliability analyses yielded an overall Cronbach's alpha coefficient of 0.98! The mean visual acuity measured in 32 eyes was -0.115 +/- 0.097 LogMAR and the mean reading acuity score was +0.026 +/- 0.091 LogRAD. The mean difference was +0.104 +/- 0.066 and the correlation between LogMAR and LogRAD was good (r = 0.59). CONCLUSIONS: With these reading charts it is for the first time possible to simultaneously determine reading acuity as well as reading speed in German. The high reliability of the 24 phrases and the high correlation between LogMAR and LogRAD leads us to expect a good reproducibility of the reading acuity evaluations. For the "Radner Reading Charts" we have shown that print size is the main reason for changes of reading speed.

Repeated readings using audiotaped material enhances oral reading in children with reading difficulties.

The method of repeated readings using audiotaped material was implemented in the present study by having poor readers aged 9-13 years listen to and read audiotaped stories until the passages could be read fluently without the tape. A same-age control group with similar reading difficulties was given an alternative reading program that was similar to that received by the experimental group (with respect to creative writing, spelling, phonics, and vocabulary development), but which differed in terms of passage reading exercises (controls read from basal readers, whereas the experimental group did repeated readings of audiotaped material). Only students in the repeated readings of audiotaped material group showed a significant effect of treatment on oral reading, whereas controls showed significantly larger gains in word attack skills. There were no between-group differences in silent reading, a close comprehension test, or isolated word recognition. The pattern of findings suggested that repeated readings of audiotaped material enhances oral reading ability of students with reading difficulties, but the effects of treatment do not generalize to a wide range of reading measures.

Learning to read is much more than learning to read: a neuropsychologically based reading program.

Departing from the observation that illiterates significantly underscore in some neuropsychological tests, a learning-to-read method named NEUROALFA was developed. NEUROALFA is directed to reinforce these underscored abilities during the learning-to-read process. It was administered to a sample of 21 adult illiterates in Colima (Mexico). Results were compared with 2 control groups using more traditional procedures in learning to read. The NEUROPSI neuropsychological test battery was administered to all the participants before and after completing the learning-to-read training program. All 3 groups presented some improvement in the test scores. Gains, however, were significantly higher in the experimental group in Orientation in Time, Digits Backward, Visual Detection, Verbal Memory, Copy of a Semi-Complex Figure, Language Comprehension, Phonological Verbal Fluency, Similarities, Calculation Abilities, Sequences, and all the recall subtests, excluding Recognition. Performance in standard reading tests was also significantly higher in the experimental group. Correlations between pretest NEUROPSI scores and reading ability were low. However, correlations between posttest NEUROPSI scores and reading scores were higher and significant for several subtests. Results are interpreting as supporting the assumption that reinforcement of those abilities in which illiterates significantly underscore results in a significant improvement in neuropsychological test scores and strongly facilitates the learning-to-read process. The NEUROALFA method of teaching reading to adult illiterates is beginning to be used extensively in Mexico. To our knowledge, this is the first attempt to apply neuropsychological principles to social problems.

Eye fixations predict reading comprehension: the relationships between reading skill, reading speed, and visual inspection.

This experiment addressed the question of whether reading comprehension and speed could be predicted by eye fixations. From a sample of university students who completed tests of reading comprehension and vocabulary, we selected a group of highly skilled readers and a group of less skilled readers. These two groups then read sentences as their eye movements were monitored, with fixation locations and durations recorded. A discriminant function analysis showed that fixation duration was a successful predictor of reading comprehension, but that the number of fixations, regressive fixations, reading speed, and vocabulary were not reliable predictors. A multiple regression analysis revealed that reading speed was predicted by the number of fixations, the average fixation duration, and the duration of the final fixation upon the sentence, but there was no relationship with reading ability. Highly skilled readers are those who can extract information efficiently, but are not necessarily those who have fast overall reading rates.

Reading in Arabic orthography: the effect of vowels and context on reading accuracy of poor and skilled native Arabic readers in reading paragraphs, sentences, and isolated words.

This study investigated the effect of vowels and context on the reading accuracy of poor and skilled native Arabic readers in reading paragraphs, sentences, and words. Central to this study is the belief that reading theory today should consider additional variables, especially when explaining the reading process in Arabic orthography among poor and normal/skilled readers. This orthography has not been studied. Reading theory today is the sum of conclusions from studies conducted in Latin orthography. The subjects were 77 native Arabic speakers, 34 of them poor readers and 44 normal/skilled readers. The subjects had to read in Arabic 15 paragraphs, 60 sentences, and 210 words. There were three reading conditions: fully vowelized, partially vowelized, and unvowelized texts. The results showed that vowels and contexts were important variables to facilitate word recognition in poor and normal/skilled readers in Arabic orthography.

Psychological behaviorism's reading therapy program: parents as reading therapists for their children's reading disability.

The study presents data on the effectiveness of a parent-administered behavioral reading therapy program. Ten parents administered the therapy program to their second- to fourth-grade children with reading disability. All 10 children received 70 therapy sessions (30 minutes per session), with 5 of the 10 children receiving approximately 51 additional sessions, for a total of 121 sessions. Parents were able to administer the program effectively, and the children participated in an enthusiastic manner. Detailed records from the therapy sessions showed a high degree of mastery of the reading materials, and the children also showed significant and clinically meaningful improvements on standardized reading measures. Although the results must be viewed cautiously given the absence of a control group, the potential of the parent-administered reading therapy program for the remediation of reading disability seems good.

Dissociation of reading strategies: letter-by-letter reading in the native language and normal reading in the learned language. A case study.

In letter-by-letter reading, which is typically observed in Dejerine's (1892) "pure alexia," oral reading seems to be mediated by the naming of the constituent letters of the printed sequence: reading time rises abnormally as a function of the number of letters of the target item. We describe a patient with fluent aphasia who showed the unusual pattern of letter-by-letter reading together with surface dyslexia in her native language (French) and apparently normal reading in the second, learned language (English). Thus, letter-by-letter reading should be considered as a description of a symptom rather than the consequence of a unique type of functional impairment.

Irlen filters and reading strategies: effect of coloured filters on reading achievement, specific reading strategies, and perception of ability.

The effect of tinted nonoptical (Irlen) lenses was investigated with 29 lens-using subjects and a control group of 31 subjects. Assessment of reading four months after the initial screening showed a significant improvement in reading rate and comprehension but not in accuracy. A significant decrease in the number of pauses while reading was also noted for the lens users as well as increases in correlation between word repetition and reading rate and accuracy. The lens users also showed significantly improved scores on a scale of attitude towards school tasks.

Comparison of reading and listening-reading techniques for administration of PIAT Reading Comprehension subtest: justification for the bypass approach.

The Peabody Individual Achievement Test (PIAT) Reading Comprehension subtest was administered to a group of 23 learning disabled children in Grades 5 through 7 who had been classified by the clinical Lexical Paradigm as good readers or poor readers. Using standardized test administration, 14 poor readers scored substantially below the 9 good readers; however, when the child was allowed to listen and read silently while the test item was read aloud, poor readers showed marked improvement in performance compared to only moderate improvement shown by the good readers. This difference in improvement between the groups was significant and resulted in poor readers achieving performance similar to that of the good readers administered the test in the standard manner.

[Preserved implicit reading and the recovery of explicit reading in a pure alexic].

We described a 55-year-old, right-handed, university-educated Japanese man who showed pure alexia after an infarction in the territory of the left posterior cerebral artery. Damage to the corpus callosum was limited to the most caudal part of the splenium. In the early days of his illness, he demonstrated the inability to read aloud on either Kana (Japanese syllabograms) or Kanji (Japanese morphograms). In contrast, he could semantically categorize Kanji-words such as animals or non-animals. Subsequently, he gradually regained the ability of reading aloud Kanji as well as Kana. At that time, we further investigated the relation between his reading ability and the attributes of 881 Kanji characters including hieroglyphicity, concreteness, and familiarity. We found that he could more readily read Kanjis with higher hieroglyphicity, concreteness, and familiarity. The reading times for Kanji-words were significantly shorter than those of corresponding Kana-words. Moreover, he showed some difficulty to read Kana-words and Kana combinations without meaning when asked to perform repetitive opposing movements with his thumb and little finger inhibiting kinesthetic reading. The effect was not observed when he read Kanji-words. These results lead us to suggest the following: (1) the two components of reading, reading aloud and comprehension abilities, are dissociable in a pure alexic, especially in Kanji reading; and (2) recovery mechanisms underlying Kanji and Kana reading were different in our case. Namely, restitution of the direct connection through the residual splenium fibers between the visual word form processing area in the right hemisphere and the left angular gyrus was attributed to Kanji reading, and utilization of kinesthetic reading played an important role in Kana reading.

Detection of lung cancer on the chest radiograph: impact of previous films, clinical information, double reading, and dual reading.

To study the impact of clinical information, previous chest radiographs, double reading (one pair of observers read the films independently) and dual reading (one pair of observers read the films simultaneously) on the sensitivity, specificity and odds ratios of observers in the detection of early lung cancer on the chest radiograph. The study was performed in 3 sessions. In the first session, 14 observers reviewed the chest radiographs of 100 cases (30 with early lung cancer, 35 with no abnormalities, 35 with other cardiopulmonary diseases). Sensitivity, specificity, odds ratios and the effect of double reading were calculated. After 4 months, a second session was held in which 7 observers reviewed all cases with the provision of all information. The other 7 observers reviewed all cases without information again. To determine the effect of dual reading, in the third session, 4 pairs of observers reviewed all cases in which they disagreed in the first independent reading session. The effects of information, double reading and dual reading on sensitivity, specificity and odds ratio were calculated. The sensitivity of the observers in the first session ranged from 0.20 to 0.60 and the specificity from 0.87 to 0.95. In the second session, these parameters changed only slightly, independent from the availability of clinical information and previous films. With double reading the sensitivity increased and specificity decreased. With dual reading sensitivity increased and specificity remained unchanged. The odds ratios were improved with double reading by 4% and with the dual reading by 14%. Additional clinical information, previous chest radiographs, double reading and dual reading have little impact on the detection of early lung cancer on the chest radiograph.

Working memory and inferences: evidence from eye fixations during reading.

Eye fixations during reading were monitored to examine the relationship between individual differences in working memory capacity-as assessed by the reading span task-and inferences about predictable events. Context sentences predicting likely events, or non-predicting control sentences, were presented. They were followed by continuation sentences in which a target word represented an event to be inferred (inferential word) or an unlikely event (non-predictable word). A main effect of reading span showed that high working memory capacity was related to shorter gaze durations across sentence regions. More specific findings involved an interaction between context, target, and reading span on late processing measures and regions. Thus, for high- but not for low-span readers, the predicting condition, relative to the control condition, facilitated reanalysis of the continuation sentence that represented the inference concept. This effect was revealed by a reduction in regression-path reading time in the last region of the sentence, involving less time reading that region and fewer regressions from it. These results indicate that working memory facilitates elaborative inferences during reading, but that this occurs at late text-integration processes, rather than at early lexical-access processes.

Comparison of paragraph comprehension test scores with reading versus listening-reading and multiple-choice versus nominal recall administration techniques: justification for the bypass approach.

Eight groups of learning disabled children (N = 100), categorized by the clinical Lexical Paradigm as good readers or poor readers, were individually administered the Gilmore Oral Reading Test, Form D, by one of four input/retrieval methods: (1) the standardized method of administration in which the child reads each paragraph aloud and then answers five questions relating to the paragraph [read/recall method]; (2) the child reads each paragraph aloud and then for each question selects the correct answer from among three choices read by the examiner [read/choice method]; (3) the examiner reads each paragraph aloud and reads each of the five questions to the child to answer [listen/recall method]; and (4) the examiner reads each paragraph aloud and then for each question reads three multiple-choice answers from which the child selects the correct answer [listen/choice method]. The major difference in scores was between the groups tested by the recall versus the orally read multiple-choice methods. This study indicated that poor readers who listened to the material and were tested by orally read multiple-choice format could perform as well as good readers. The performance of good readers was not affected by listening or by the method of testing. The multiple-choice testing improved the performance of poor readers independent of the input method. This supports the arguments made previously that a "bypass approach" to education of poor readers in which testing is accomplished using an orally read multiple-choice format can enhance the child's school performance on reading-related tasks. Using a listening while reading input method may further enhance performance.

The reading Miscue Inventory. A promising approach to diagnosis of the reading-disabled.

Reading Miscue Inventory--RMI--opens avenues of dealing with the reading process in a scientific and process-oriented fashion which can lead to further refining of the theoretical base upon which reading is founded as well as providing diagnostic information for use by reading specialists. From such information, reading specialists are able to develop remediation on an individualized basis. Appropriate materials, procedures, and practices are developed from the qualitative analysis of miscues rather than from the information provided by standardized achievement or diagnostic reading tests. In sights are gained regarding a child's ability to use the complex process of reading. Remediation of disability, at the appropriate place in the process, is based on assumptions regarding the interrelationship of thought and language. Reading specialists are looking to psycholinguists for theoretical bases upon which to build models of the reading process. Qualitative miscue analysis is based upon recently proposed notions of the psycholinguistic nature of reading. Common concepts and understanding regarding reading and assessment of reading disability may facilitate learning disability teams in their diagnostic and remedial procedures. Until recently, these discussions have occurred mainly in reading-related research and in education circles, but learing disabilities teams are beginning to participate in the refining and clarifying of these notions of assessment and remediation. Regardless of the eventual outcome, the necessity for considering these views is basic to a fuller understanding of ways in which learning-disabled children may be helped.

Reading unspaced text: implications for theories of reading eye movements.

According to current theories of reading, the reader's saccades are guided primarily by spaces between words, clearly the most prominent visual feature in most modern texts. This belief was investigated by recording eye movements with unprecedented accuracy and precision while subjects read spaced and unspaced passages both silently and aloud. Modest increases in fixation durations and decreases in overall reading speed were observed when unspaced texts were read. However, subjects read unspaced texts with the same level of comprehension and percentage of regressions as they read spaced texts. The only global eye movement parameter that changed appreciably when spaces were removed was progressive (rightward) saccade length. Progressive saccades were shorter in unspaced texts. However, unspaced texts were denser and narrower because they were constructed so as to contain the same number of words/line as the spaced texts. This meant that unspaced texts contained more informational characters/degree of visual angle. The observed decrease in progressive saccade lengh tended to be proportional to this increase in text density. Therefore, the number of saccades/line of text remained approximately the same in both spaced and unspaced texts. Furthermore, a detailed examination of local eye movement properties, i.e. where within words the subjects fixated and how many times they fixated words of different lengths, suggested that the same oculomotor strategy was used for reading spaced and unspaced texts. This was true for both silent reading and reading aloud. Thus, a model that could explain reading spaced texts could also explain reading unspaced texts with only a change of a single global parameter, namely, saccade length. We conclude that the current tendency to emphasize spaces as guides to reading eye movements must be reconsidered. Words, not spaces, may serve as the perceptual units that guide the line of sight through the text.

Psychophysics of reading. XX. Linking letter recognition to reading speed in central and peripheral vision.

Our goal is to link spatial and temporal properties of letter recognition to reading speed for text viewed centrally or in peripheral vision. We propose that the size of the visual span - the number of letters recognizable in a glance - imposes a fundamental limit on reading speed, and that shrinkage of the visual span in peripheral vision accounts for slower peripheral reading. In Experiment 1, we estimated the size of the visual span in the lower visual field by measuring RSVP (rapid serial visual presentation) reading times as a function of word length. The size of the visual span decreased from at least 10 letters in central vision to 1.7 letters at 15 degrees eccentricity, in good agreement with the corresponding reduction of reading speed measured by Chung and coworkers (Chung, S. T. L., Mansfield, J. S., & Legge, G. E. (1998). Psychophysics of reading. XVIII. The effect of print size on reading speed in normal peripheral vision. Vision Research, 38, 2949-2962). In Exp. 2, we measured letter recognition for trigrams (random strings of three letters) as a function of their position on horizontal lines passing through fixation (central vision) or displaced downward into the lower visual field (5, 10 and 20 degrees ). We also varied trigram presentation time. We used these data to construct visual-span profiles of letter accuracy versus letter position. These profiles were used as input to a parameter-free model whose output was RSVP reading speed. A version of this model containing a simple lexical-matching rule accounted for RSVP reading speed in central vision. Failure of this version of the model in peripheral vision indicated that people rely more on lexical inference to support peripheral reading. We conclude that spatiotemporal characteristics of the visual span limit RSVP reading speed in central vision, and that shrinkage of the visual span results in slower reading in peripheral vision.

Psychophysics of reading. XVIII. The effect of print size on reading speed in normal peripheral vision.

Reading in peripheral vision is slow and requires large print, posing substantial difficulty for patients with central scotomata. The purpose of this study was to evaluate the effect of print size on reading speed at different eccentricities in normal peripheral vision. We hypothesized that reading speeds should remain invariant with eccentricity, as long as the print is appropriately scaled in size--the scaling hypothesis. The scaling hypothesis predicts that log-log plots of reading speed versus print size exhibit the same shape at all eccentricities, but shift along the print-size axis. Six normal observers read aloud single sentences (approximately 11 words in length) presented on a computer monitor, one word at a time, using rapid serial visual presentation (RSVP). We measured reading speeds (based on RSVP exposure durations yielding 80% correct) for eight print sizes at each of six retinal eccentricities, from 0 (foveal) to 20 deg in the inferior visual field. Consistent with the scaling hypothesis, plots of reading speed versus print size had the same shape at different eccentricities: reading speed increased with print size, up to a critical print size and was then constant at a maximum reading speed for larger print sizes. Also consistent with the scaling hypothesis, the plots shifted horizontally such that average values of the critical print size increased from 0.16 deg (fovea) to 2.22 deg (20 deg peripheral). Inconsistent with the scaling hypothesis, the plots also exhibited vertical shifts so that average values of the maximum reading speed decreased from 807 w.p.m. (fovea) to 135 w.p.m. (20 deg peripheral). Because the maximum reading speed is not invariant with eccentricity even when the print size was scaled, we reject the scaling hypothesis and conclude that print size is not the only factor limiting maximum reading speed in normal peripheral vision.

[Reading ability and need for reading aids, inadequate management of a nursing home population].

INTRODUCTION: In our society people are getting older and often become handicapped and immobile. Reading then is one of their main passtime and very important for their social integration and independence. PATIENTS AND METHODS: Seventy-seven (6 males, 71 females) randomly chosen elderly people (age ranged from 77 to 94 years, mean: 85.5 years) staying in nursing homes were examined concerning their reading ability of newspaper print with their own reading equipment. Exclusion criteria were extensive organic diseases and impaired mental ability, such as dementia. Relevant anamnestic data, including ophthalmologic, family and social history were ascertained by questionnaire. Special attention was given to visual acuity for near distance, reading ability, motivation and personal reading aids. Further questions dealt with general diseases, medication, social contacts inside and outside the nursing homes and the former occupation of the patient. If reading of newspaper print with individual glasses was impossible, the effect of magnification was evaluated and the magnification factor was determined (Zeiss reading charts). RESULTS: Thirty-eight people (45%) were unable to read with their own reading glasses. 91% of them regained reading ability by magnification, they had inadequate visual aids. 77% of this group had a magnification requirement of 1 to 3 times, 14% needed 10 to 25 times of magnification and 9% more than 25 times. Only one person had an electronic magnifying reading system (CCTV). CONCLUSION: Reading aids of elderly people very frequently are insufficient. Magnification can be helpful in most cases and various magnification systems are available. With this support elderly people could regain their quality of life, their independence and socialization. Nursing costs could also be reduced.
