Discourse Complexity of College Writers With and Without Disabilities
Authors: Gregg Noel , Coleman Chris , Stennett Robert B. , Davis Mark
Published: December 2007

The purpose of this study was to examine specific word- and sentence-level features most frequently used in the expository writing of four groups of college writers. Three groups were writers who demonstrated disabilities. Group 1 students ( n = 87) demonstrated learning disabilities (LD); Group 2 ( n = 50), attention-deficit/hyperactivity disorder (ADHD); and Group 3 ( n = 58), combined LD and ADHD. Group 4 consisted of writers with no history of a documented disability ( n = 92). Computer-based analysis and structural equation modeling were used to group specific linguistic features identified in the expository essays across all four groups. The frequency of linguistic features, not errors, was analyzed. Four communication dimensions (factors) were identified for the four groups of writers, but the factor loadings and correlations were significantly different across groups. Furthermore, the relationships of specific linguistic features were studied as to their impact on the verbosity, quality, and lexical complexity of students' expository essays. It is interesting to note that very high correlations were found between verbosity, quality, and lexical complexity, suggesting that these constructs are not as separate in their functioning as might be supposed. Implications for assessment and instruction are provided.
Writing and Reading
Authors: Berninger Virginia W. , Abbott Robert D. , Abbott Sylvia P. , Graham Steve , Richards Todd
Published: December 2007

Four approaches to the investigation of connections between language by hand and language by eye are described and illustrated with studies from a decade-long research program. In the first approach, multigroup structural equation modeling is applied to reading and writing measures given to typically developing writers to examine unidirectional and bidirectional relationships between specific components of the reading and writing systems. In the second approach, structural equation modeling is applied to a multivariate set of language measures given to children and adults with reading and writing disabilities to examine how the same set of language processes is orchestrated differently to accomplish specific reading or writing goals, and correlations between factors are evaluated to examine the level at which the language-by-hand system and the language-by-eye system communicate most easily. In the third approach, mode of instruction and mode of response are systematically varied in evaluating effectiveness of treating reading disability with and without a writing component. In the fourth approach, functional brain imaging is used to investigate residual spelling problems in students whose problems with word decoding have been remediated. The four approaches support a model in which language by hand and language by eye are separate systems that interact in predictable ways.
Using Semantics, Grammar, Phonology, and Rapid Naming Tasks to Predict Word Identification
Authors: Hammill Donald D. , Mather Nancy , Allen Elizabeth A. , Roberts Rhia
Published: December 2007

This study investigated the relative importance of semantic, grammatical, phonological, and rapid naming abilities in predicting word identification in a large, representative sample of children enrolled in first through sixth grade, using correlation, factor analysis, multiple regression, and predictive outcome analysis techniques. Composite measures of these abilities were found to correlate significantly with word identification, even after controlling for the effects of nonverbal intelligence. Factor analysis indicated that the spoken language composites and the word identification composite loaded on one factor, whereas the perceptual speed composites loaded on a second factor. Multiple regression analyses showed that among younger children in the early stages of learning to read and children whose word identifying skills were below average, the phonology and rapid naming composites accounted for the most variance in predicting word identification skills. Among older children and children who were proficient in word identification, the semantics composite accounted for the most variance. The most important analyses in this study (i.e., the calculations of the sensitivity indexes, the specificity indexes, and the positive predictive values) evaluated the practical value of using the composites to predict poor word identification skills in children. To be considered practically useful, all predictive outcome values had to be .75 or greater. None of the composites studied, including an application of the double-deficit hypothesis, met this criterion. The results from this study question the accuracy and utility of using any of the abilities studied to predict which students are at risk for or have poor word identification skills.
Sound-Symbol Learning in Children with Dyslexia
Authors: Gang Marjorie , Siegel Linda S.
Published: December 2007

This study evaluated the effect of sound-symbol association training on visual and phonological memory in children with a history of dyslexia. Pretests of phonological and visual memory, a sound-symbol training procedure, and phonological and visual memory posttests were administered to children with dyslexia, to children whose dyslexia had been compensated through remedial training, and to age- and reading level-matched comparison groups. Deficits in visual and phonological memory and memory for sound-symbol associations were demonstrated in the dyslexia group. For children with dyslexia and children whose dyslexia had been remediated, the sound-symbol training scores were significantly associated with word and pseudoword reading scores and were significantly lower than those of the comparison groups. Children with dyslexia and children whose dyslexia had been compensated showed significantly less facilitation of phonological memory following the training than did typical readers. Skilled readers showed some reduction in accuracy of visual memory following the training, which may be the result of interference of verbalization with a predominantly visual task. A parallel decrease was not observed in the children with dyslexia, possibly because these children did not use the verbal cues. Children with dyslexia and children whose dyslexia had been compensated seemed to have difficulty encoding the novel sounds in memory. As a result, they derived less phonological memory advantage and less visual memory interference from the training than did typical readers. Children in the compensated dyslexia group scored lower on sound-symbol training than their age peers. In other respects, the scores of these children were equivalent to those of the typically reading comparison groups. Children in the compensated dyslexia group exhibited higher phonological rehearsal, iconic memory, and associative memory scores than children in the dyslexia group. Implications for the remediation of dyslexia are discussed.
The Misconception of the Regression-Based Discrepancy Operationalization in the Definition and Research of Learning Disabilities
Authors: Van den Broeck Wim
Published: December 2007

In this article, I argue that the regression-based discrepancy method used in the diagnosis of learning disabilities is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. I mathematically demonstrate that the regression-based discrepancy method largely reflects achievement-specific determinants, thereby defeating its own object of describing aptitude-achievement discrepancies. The implications for research examining the role of intelligence in learning disabilities are outlined.
Misconceptions in Van den Broeck's Representation of Misconceptions About Learning Disability Research
Authors: Willson Victor L. , Reynolds Cecil R.
Published: December 2007

The methods and conclusions of Van den Broeck (in this issue) are evaluated from two perspectives: (a) statistical considerations and (b) theoretical models of IQ and achievement, specifically reading achievement. We consider the statistical model proposed by Van den Broeck for the regression-based discrepancy model (RDM) to be either irrelevant or conceptually inconsistent with current models of IQ and achievement. The resulting simulation produced exemplar cases that are not realistic in terms of practice. The theoretical representations of IQ and achievement were, in our understanding, inconsistent with contemporary models of either. We suggest that acceptable models support the use of the RDM as it has been proposed by us and by others as one component of the determination of the presence or absence of a learning disability.
Will the Real Discrepant Learning Disabilit Please Stand Up?
Authors: Van den Broeck Wim
Published: December 2007

Willson and Reynolds (in this issue) challenged my thesis that the regression-based discrepancy method (RDM) is not a valid tool to detect aptitude-achievement discrepancies. In this response, I show that the statistical and theoretical counterarguments of Willson and Reynolds are based on a misreading of the statistical models presented. Furthermore, I demonstrate that the regression adjustment, which is largest for lower correlations, is the direct source of the lack of validity of the RDM procedure. Nevertheless, RDM can be considered a valid method to measure an achievement component that is unrelated to intelligence.
The Incidence and Nature of Letter Orientation Errors in Reading Disability
Authors: Terepocki Megan , Kruk Richard S. , Willows Dale M.
Published: December 2007

Letter orientation confusions (reversals) in the reading and writing of 10-year-old children with and without reading disability were investigated to determine whether reading disability is associated with letter orientation errors and to identify the nature of the errors. In a variety of tasks measuring letter orientation confusions in reception (reversal detection and recognition) and production (controlled writing, copying), individuals with reading disability made more orientation confusions than average readers. Orientation errors were more frequent for reversible than for nonreversible items in tasks involving long-term memory processes. The results did not appear to be related to group differences in attention or speed of motor responding. Possible sources of orientation confusions, including deficient magnocellular system processing, mislabeling, and overreliance on visual strategies, are discussed.
Relationship of Rapid Automatized Naming and Phonological Awareness in Early Reading Development
Authors: Schatschneider Christopher , Carlson Coleen D. , Francis David J. , Foorman Barbara R. , Fletcher Jack M.
Published: December 2007

It is widely accepted that deficits in phonological awareness skills are related to reading difficulties. Recently, another source of reading difficulty has been identified that involves naming speed, and combined impairments in phonological skills and naming speed will produce more severe reading deficits than single deficits in either of these cognitive skills. The purpose of this study was to investigate the consequences of grouping children based on the presence or absence of deficits in these skills. We demonstrate that the greater severity of reading impairment found in children with a double deficit could be due in part to a statistical artifact caused by grouping children based on their performance on two correlated continuous variables. This artifact also makes it difficult to establish the relative impact of deficits in naming speed on reading ability independent of deficits in phonological awareness.
Lexical Access in College Students with Learning Disabilities
Authors: Rubin Scott S. , Johnson Clinton M.
Published: December 2007

The purpose of this study was to compare the semantic processing abilities of college students with learning disabilities (LD) to those of their peers without learning disabilities (NLD) who were matched for age, gender, and intelligence. Participants were compared on results from the Test of Adolescent/Adult Word Finding (TAWF) and from event-related potential (N400) sampling to the processing of semantically incongruous sentences. The LD and NLD groups did not significantly differ in accuracy on the TAWF; however, students with LD demonstrated a significantly greater number of delayed responses. The LD group's N400 responses were significantly delayed at the Pz electrode site. Effect size indicators also revealed somewhat reduced amplitudes at Fz and Cz locations. The significant delays of the students with LD on standardized testing and on N400 suggest an inefficiency in the semantic processing of these individuals, in both automatic and attention-based aspects of lexical access.
Sleep Disturbances in Adolescents with Symptoms of Attention-Deficit/Hyperactivity Disorder
Authors: Stein Daniel , Pat-Horenczyk Ruth , Blank Shulamit , Dagan Yaron , Barak Yoram , Gumpel Thomas P.
Published: December 2007

We evaluated 32 nonmedicated male adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) in childhood, 35 male adolescents similarly diagnosed who were receiving methylphenidate (MPH), and 77 control boys. Both ADHD groups completed self-report questionnaires assessing sleep disturbances; weekday and holiday sleep duration; and symptoms of ADHD, anxiety, and depression. Parents and teachers rated the severity of the participants' ADHD. The control group completed self-report questionnaires assessing sleep disturbances. We found that nonmedicated participants and controls did not differ in the severity of sleep disturbance. In contrast, the medicated participants demonstrated a significantly greater severity of sleep disturbance compared with the nonmedicated participants and reported elevated levels of symptoms of ADHD, anxiety, and depression. Specific analyses showed that depressive symptoms contributed significantly to the degree of sleep disturbance when controlling for ADHD diagnosis and MPH treatment. These findings suggest that among adolescents with ADHD symptoms, the severity of symptoms of depression may contribute to the degree of sleep disturbance in addition to the effect of their primary disorder and MPH treatment.
EEG Analysis of Children with Attention-Deficit/Hyperactivity Disorder and Comorbid Reading Disabilities
Authors: Clarke Adam R. , Barry Robert J. , McCarthy Rory , Selikowitz Mark
Published: December 2007

This study investigated electroencephalographic differences between two groups of children with attention-deficit/hyperactivity disorder, combined type, with reading disabilities (ADHD + RD) or without (ADHD) and typical control participants. Twenty participants were included in each group. All participants were between the ages of 8 and 12 years, and groups were matched on age and gender. The electroencephalographic (EEG) was recorded during an eyes-closed resting condition from 21 monopolar derivations, which were clustered into nine regions for analysis. The EEGs were Fourier-transformed to provide absolute and relative power estimates for the delta, theta, alpha, and beta bands. Ratio coefficients were also calculated for the theta/alpha and theta/beta ratios. Compared with controls, the clinical groups demonstrated the increased slow-wave and reduced fast-wave activity commonly reported in the ADHD literature. The ADHD + RD group had more relative theta, less relative alpha, and a higher theta/alpha ratio than the ADHD group. A number of hemispheric differences were also found in the delta and alpha bands. These results suggested that some of the EEG divergences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability that is independent of the EEG divergences found in ADHD.
Remedial Interventions for Children with Reading Disabilities
Authors: Gonzalez Maria del Rosario Ortiz , Garcia Espinel Ana I. , Guzman Rosquete Remedios
Published: December 2007

The effects of two types of phonological training in children with reading disabilities (RD) were examined. One of the programs (SP/LPA) trained children in speech discrimination, letter—sound correspondence, and phonemic awareness. The other program (LPA) trained children only in letter—sound correspondence and phonemic awareness. The effects of these programs were compared with a control group. Thirty-five children with RD were trained in small groups five times a week for 4 weeks. The results indicated that both experimental groups improved in phonemic awareness compared to the control group but that only the SP/LPA group scored higher than the control group in reading.
Goal Importance and Students at Risk of Having Language Difficulties
Authors: Sideridis Georgios D.
Published: December 2007

The purpose of this study was to compare the motivational determinants of students at risk of language difficulties (in reading and spelling) and students with high language skills. Teachers' evaluations in language and mathematics at the end of the academic year constituted the dependent variable. Motivational orientations were examined using the constructs that reflect the theory of planned behavior and goal importance. Participants were 202 elementary school students—22 at risk of language difficulties and 180 with high language skills—drawn from 30 elementary schools in northern Greece. The results indicated that the two groups differed significantly, with the at-risk students exhibiting significantly lower perceptions of goal importance, intention to achieve, belief strength, outcome evaluation, and normative beliefs, and eventually scoring lower in language and mathematics at the end of the academic year. A finer analysis of students' motivational orientations was conducted using covariance structural modeling (CSM) and EQS 5.7b. The planned behavior model with goal importance produced a comparative fit index (CFI) of 1.00 in language and mathematics for the at-risk group. The respective CFIs for the high language skills group were .97 and 1.00 in language and mathematics, respectively. Although model fit was excellent across samples, different weights and signs linking motivational orientations to achievement partly explained the observed differences in language and mathematics manifested in the two groups.
ADA-Based Accommodations in Higher Education
Authors: Gordon Michael , Lewandowski Lawrence , Murphy Kevin , Dempsey Kim
Published: December 2007

The expansion of the number of students requesting accommodations in postsecondary settings compels clinicians to become knowledgeable about the legal definitions and documentation requirements of the Americans with Disabilities Act (ADA). Because the law is relatively new, courts and regulatory agencies have only recently begun to clarify what constitutes a disability. In this study, 147 clinicians completed a questionnaire developed to assess their understanding of the law and the diagnostic approaches they used to justify claims of learning disability (LD), attention-deficit/hyperactivity disorder (ADHD), and psychiatric disability. Whereas the clinicians agreed on certain points (e.g., the right of institutions to formulate specific policies regarding documentation), they substantially disagreed on several fundamental issues. Clinician consensus was lowest on items that asked about the basic intent of the law, the metrics for assessing impairment, and the criteria for assessing ADHD in adulthood. Judged against the legislative history of the ADA and the body of regulatory rulings and legal decisions, many clinicians' responses showed a need for clarification regarding the distinction between special education law and the antidiscrimination intent of the ADA. The respondents also expressed a nearly uniform wish for more training in this fast-growing area of clinical practice.
A Synthesis of Research on Effective Interventions for Building Reading Fluency with Elementary Students with Learning Disabilities
Authors: Chard David J. , Vaughn Sharon , Tyler Brenda-Jean
Published: December 2007

Fluent reading, often defined as speed and accuracy, is an important skill for all readers to develop. Students with learning disabilities (LD) often struggle to read fluently, leading to difficulties in reading comprehension. Despite recent attention to reading fluency and ways to improve fluency, it is not clear which features of interventions that are designed to enhance fluency are beneficial for the most struggling readers. The purpose of this study is to synthesize research on interventions that are designed primarily to build reading fluency for students with LD. The search yielded 24 published and unpublished studies that reported findings on intervention features, including repeated reading with and without a model, sustained reading, number of repetitions, text difficulty, and specific improvement criteria. Our findings suggest that effective interventions for building fluency include an explicit model of fluent reading, multiple opportunities to repeatedly read familiar text independently and with corrective feedback, and established performance criteria for increasing text difficulty.
Exploring Hypotheses About Phonological Awareness, Memory, and Reading Achievement
Authors: Tractenberg Rochelle E.
Published: December 2007

Reading-related skills were tested in adults with and without reading disabilities (RD) and adults with profound hearing impairment (PHI) who did not differ on average Performance IQ. The RD group and the PHI group both demonstrated levels of phonological awareness lower than the control group's, but only the RD group also exhibited deficits in other skills, including verbal short-term memory, morphological awareness, speeded written naming, and reading comprehension. The average reading level of the PHI group was significantly higher than that of the RD group. Three control group members also demonstrated limited phonological awareness without other deficits in a pilot study, performing similarly to the PHI group. The results support other studies suggesting that processes dependent on memory, not solely phonological awareness, may contribute to determining reading achievement.
Separating Genuine Cases of Reading Disability From Reading Deficits Caused by Predominantly Inattentive ADHD Behavior
Authors: Aaron P.G. , Joshi R.M. , Palmer Hyyon , Smith Natasha , Kirby Edward
Published: December 2007

Conventional methods of differentiating reading disability (RD) caused by deficits in decoding skills or comprehension from poor reading performance caused by inconsistent attention associated with attention-deficit/hyperactivity disorder (ADHD) have produced equivocal results. This study presents a model of differential diagnosis of attentional problems and RD that differs from these conventional approaches. The new diagnostic procedure uses intraindividual differences seen in the performance of at-risk learners on tasks related to reading that vary in their sensitivity to the sustained attention required for successful performance. The hypothesis is that children with inconsistent attention would perform more poorly on tests that require sustained attention, such as listening comprehension, than on tests that are more tolerant of inattention, such as reading comprehension. Such differences would not be seen in the test scores of children who have only RD, because their performance is determined more by the difficulty level of the reading tests than by the degree of sensitivity of the task to attention. The validity of this new model was evaluated by determining the capability of the differences seen in the scores of tests that differ in their sensitivity to sustained attention to predict the degree of inconsistency in sustained attention as measured by a continuous performance test. The data obtained from 39 children who are at risk for RD suggest that this is a viable model.
The Use of Think-Aloud Protocols to Compare Inferencing Abilities in Average and Below-Average Readers
Authors: Laing Sandra P. , Kamhi Alan G.
Published: December 2007

In this study, we examined whether think-aloud procedures would uncover differences in the kinds of inferences generated by average and below-average readers. Participants were 40 third-grade children who were divided into groups of average and below-average readers. All participants completed measures of nonverbal IQ, reading, language, and working memory, and a story comprehension task that consisted of two conditions: listen through and think aloud. The major findings in this study were that (a) average readers generated significantly more explanatory inferences than below-average readers, and (b) comprehension performance as measured by story recall was significantly better for both groups in the think-aloud condition than in the listen-through condition. The discussion addresses the implications of these findings.
The Transition From High School to Postsecondary Education for Students with Learning Disabilities
Authors: Janiga Sandra J. , Costenbader Virginia
Published: December 2007

Federal legislation requires that students with disabilities receive services to assist them in the transition from high school to postsecondary life. Transition services must address students' understanding of their disability, learning strengths and weaknesses, career decision—making skills, and preparation for the increased demands of postsecondary education. This study surveyed coordinators of special services for students with disabilities at 74 colleges and universities in New York state. Respondents provided their perceptions of how well the students they served had been prepared by the transition services they had received in high school. Overall, little satisfaction with transition services was expressed. Respondents were most satisfied with high schools' provision of updated evaluations for students prior to enrollment in college, and they rated students' preparation for self-advocacy as the greatest weakness of current transition services.
One Size Still Does Not Fit All in Specific Learning Disability Assessment Across Ethnic Groups
Authors: Warner Tamara D. , Dede Duane E. , Garvan Cynthia W. , Conway Timothy W.
Published: December 2007

The use of IQ scores and discrepancy formulas for identifying specific learning disabilities (SLD) has been widely discredited by prominent researchers for more than a decade. Nevertheless, the overwhelming majority of state policies still specify the use of discrepancy formulas, including the simple difference method, which is psychometrically inferior to regression-based methods. This study compares the use of a minimum IQ cutoff score and a simple difference method versus a regression-based method for identifying SLD in a sample of African American and European American full-time college students ( N = 117). Replicating the findings from previous studies using typically achieving children, typically achieving adults, and school-age children with SLD, this study adds to the chorus of voices criticizing the use of outdated assessment practices that can have deleterious effects for individuals with SLD. The implications for legislative policy are discussed in the context of the historical overrepresentation of African Americans in all special education categories except SLD and the increased access to higher education that students with SLD have gained during the past decade.
The Role of Speed of Processing, Rapid Naming, and Phonological Awareness in Reading Achievement
Authors: Catts Hugh W. , Gillispie Matthew , Leonard Laurence B. , Kail Robert V. , Miller Carol A.
Published: December 2007

This study investigated the role of speed of processing, rapid naming, and phonological awareness in reading achievement. Measures of response time in motor, visual, lexical, grammatical, and phonological tasks were administered to 279 children in third grade. Measures of rapid object naming, phonological awareness, and reading achievement were given in second and fourth grades. Reading group comparisons indicated that poor readers were proportionally slower than good readers across response time measures and on the rapid object naming task. These results suggest that some poor readers have a general deficit in speed of processing and that their problems in rapid object naming are in part a reflection of this deficit. Hierarchical regression analyses further showed that when considered along with IQ and phonological awareness, speed of processing explained unique variance in reading achievement. This finding suggests that a speed of processing deficit may be an “extraphonological” factor in some reading disabilities.
Mathematical Problem-Solving Profiles of Students with Mathematics Disabilities With and Without Comorbid Reading Disabilities
Authors: Fuchs Lynn S. , Fuchs Douglas
Published: December 2007

The purpose of this study was to describe the mathematical problem-solving profiles of students with mathematics disabilities (MD) with and without comorbid reading disabilities (RD). The disability status of fourth-grade students was verified through testing ( n = 18 MD; n = 22 MD + RD). Then a hierarchy of mathematics problem-solving tasks was administered. The results demonstrated large deficits for both groups; however, the differences between students with MD and those with MD + RD were mediated by the level of problem solving (arithmetic story problems vs. complex story problems vs. real-world problem solving) and by performance dimension (operations vs. problem solving). On arithmetic story problems, the differences between the disability subtypes were similar for operations and problem solving. By contrast, on complex story problems and real-world problem solving, the differences between the subtypes were larger for problem solving than for operations.
Impaired Visual Attention in Children with Dyslexia
Authors: Heiervang Einar , Hugdahl Kenneth
Published: December 2007

Reading involves the correct and rapid identification of visual stimuli with letters and words. The processing of visual stimuli depends not only on the integrity of the peripheral and central visual system but also on the attentional systems involved. In the present study, a cue—target visual attention task was administered to a population-based sample of 25 children with dyslexia from 10 to 12 years of age. A control group matched for group size, age, and gender was obtained from the same general population. A two-stage screening process involved a spelling task of regular words followed by a battery of five single-word reading tasks. The cue—target task involved both a computer-controlled stimulus presentation and a computer-controlled measurement of reaction time. The data were analyzed by visual field, cue condition (valid, invalid, and no cue), and cue—target interval (CTI). The results showed a general pattern of slower responses in the dyslexia group compared to the control group. The dyslexia group also had longer reaction times in the short CTI condition (covert shift of attention) and in the long CTI condition (overt shift of attention). The findings may reflect a general attentional deficit to visual stimuli in dyslexia, possibly related to problems with the recruitment of necessary cognitive resources for the performance of complex reaction time tasks and for fluent reading.
The Play and Language Behavior of Mothers With and Without Dyslexia and Its Association to Their Toddlers' Language Development
Authors: Lyytinen Paula , Eklund Kenneth , Lyytinen Heikki
Published: December 2007

The play and language behavior of mothers with ( n = 49) and without ( n = 49) specific reading disabilities (RD) was investigated during play with their 14-month-old children. The contribution of maternal behavior to the language development of their children was examined. The children's receptive and expressive language skills were assessed longitudinally at 14, 18, and 30 months, using the MacArthur Communicative Development Inventories and the Reynell Developmental Language Scales. Children with and without familial risk for RD did not differ from each other in any play or language measures at these ages. No group differences were found for mothers' manifestations of nonsymbolic play and language. However, the typically reading (TR) mothers produced significantly more symbolic play and language in play interactions with their child than did the mothers with RD. The correspondence between mother—child symbolic play and maternal play-related language was also higher for the TR group than it was for the RD group. The mothers' symbolic play did not show any relation to their children's language development, but their expressions of symbolic language did show a relationship. The mothers' child-directed symbolic language contributed significantly toward the comprehension skills of 14- and 18-montholds in the RD group. This association, however, was lower at 30 months, at which point it was reliably present for the first time in the TR group.
Students with Learning Disabilities in Higher Education
Authors: Heiman Tali , Precel Karen
Published: December 2007

This study compared 191 college students with learning disabilities (LD) and 190 students without LD in four main areas: academic difficulties, learning strategies, functioning during examinations, and students' perception of factors that help or impede their academic success. Analysis of the personal data of students with and without LD revealed no significant differences between groups on grade point average, number of courses taken, and family status, but students with LD reported having more difficulties in humanities, social sciences, and foreign language than students without LD. Regarding academic strategies, students with LD devised unusual strategies and preferred additional oral explanations or visual explanations, whereas nondisabled students preferred more written examples. These differences indicated that students without LD used more written techniques than did students with LD. During examinations, the students with LD had difficulty concentrating and were concerned about lack of time. They experienced stress, were nervous, and felt more frustrated, helpless, or uncertain during examinations than students without LD. The implications for college students with LD are discussed.
Evidence for Unexpected Weaknesses in Learning in Children with Attention-Deficit/Hyperactivity Disorder Without Reading Disabilities
Authors: Cutting Laurie E. , Koth Christine W. , Mahone E. Mark , Denckla Martha B.
Published: December 2007

This study examined the mechanisms underlying verbal learning in children with and without attention-deficit/hyperactivity disorder (ADHD), none of whom had reading disabilities. Children with ADHD were compared to typically developing children on both process and product scores from the California Verbal Learning Test for Children. The findings indicated that children with ADHD initially learned the same number of words as controls but showed weaknesses recalling the words after delays, suggesting that children with ADHD are less efficient learners. Regardless of ADHD status, boys and girls performed differently. Boys used semantic clustering less frequently and recalled fewer words from the middle region of the list than girls; girls also outperformed boys in terms of overall performance, despite lower verbal IQ scores. These findings show that children with ADHD can exhibit unexpected weaknesses in learning even without a formal learning disability. Gender differences in verbal learning are also illustrated.
Comparing the Self-Concept of Students With and Without Learning Disabilities
Authors: Gans Amy M. , Kenny Maureen C. , Ghany Dave L.
Published: December 2007

This study compared self-concept in 50 middle school children with learning disabilities (LD) and 70 of their peers without LD. The students, primarily Hispanic, completed the Piers-Harris Children's Self-Concept Scale, and each obtained a score in six subdomains. Differences were found between the groups on the Intellectual and School Status and Behavior subscales, with students without LD scoring higher on both scales. There was no difference between groups on global self-concept. The limitations of this study are identified, and directions for future research are provided.
A Rapid Screening Measure for the Identification of Visuospatial Learning Disability in Schools
Authors: Cornoldi Cesare , Venneri Annalena , Marconato Fabio , Molin Adriana , Montinari Cinzia
Published: December 2007

Verbal and nonverbal forms of developmental learning disabilities have been reported. Whereas there are several instruments for evaluating children for the presence of verbal learning disabilities at school, no screening tool is available to identify children who have nonverbal learning disabilities. This study aimed at devising and validating a short screening questionnaire that can be used by teachers in primary schools to identify those children who need to be referred for clinical services because they have a visuospatial learning disability (VSLD). An 18-item Shortened Visuospatial Questionnaire (SVS) was derived from an earlier, longer version. Its validation procedure was twofold and was achieved by (a) verifying that children who had been identified with the SVS questionnaire as having a VSLD actually showed visuospatial deficits on psychometric evaluation and by (b) rating with the SVS a clinically identified population of children with VSLD. The results of the validation procedure showed that the SVS is a quick, reliable, and valid instrument that may be helpful in identifying children with VSLD in primary school.
Dyslexia and Dysgraphia
Authors: Mather David S.
Published: December 2007

A dual-task paradigm involving concurrent finger tapping and line orientation judgment was used to investigate brain processing differences in early adolescent good readers/poor spellers (dysgraphia), poor readers/poor spellers (dyslexia) and good readers/good spellers. Whereas all groups were similarly affected during the left-hand tapping condition, in the right-hand tapping condition the good spelling group displayed significantly less tapping disruption than both poor spelling groups, who did not differ significantly from each other. From these results, it can be inferred that individuals with dyslexia and dysgraphia share a left-hemisphere processing limitation that is not confined to written language. In light of other relevant research findings, I suggest that this limitation is due to the absence of a disembedding scanning mechanism for converting spatial arrays (e.g., spelling patterns) to temporal form—an impairment putatively caused by attempting to teach written language to children who are late in establishing left-hemisphere motor dominance.
Children at Risk for Learning Disorders: Multiple Perspectives
Authors: Al-Yagon Michal
Published: December 2007

This study examined the contribution of a multidimensional model of risk factors in explaining adaptive functioning among 5- to 6.5-year-old kindergartners with mild developmental delays who were considered at risk for developing learning disorders. Risk factors included (a) child characteristics, (b) maternal and familial ecological variables, and (c) the child's attachment style as perceived by the mother. The sample included 145 Israeli mother—child dyads: 70 mothers and their children at risk for developing learning disorders (51 boys, 19 girls) and 75 mothers and their typically developing children (46 boys, 29 girls) from the same general education kindergartens. Data were collected from children's self-reports, mothers' narratives, and teachers' ratings. Path analysis examined the multidimensional risk model for the two groups. The study indicated a high fit between the theoretical model and the empirical findings and showed a different pattern of relations between the model's components for the two populations studied.
Learning Disabilities and Bullying
Authors: Mishna Faye
Published: December 2007

Independently, learning disabilities (LD) and involvement in bullying each pose a risk for social, emotional, and behavioral problems. Based on the research to date and on the characteristics common to children with LD and children who are bullied, there is reason to believe that children with LD are at increased risk of victimization. However, there is little research on the relationship between LD and bullying. This article presents factors and characteristics that make children and youth with LD vulnerable to bullying. Risk factors and effects of bullying are reviewed. Implications for practice and research are discussed.

This replication study compared 86 petition students who received course substitutions for the college foreign language (FL) requirement with 40 nonpetition students who fulfilled the FL requirement by passing FL courses on cognitive and academic achievement measures and graduating grade point average. The results showed significant differences between the two groups, favoring the nonpetition group on one measure, the American College Testing (ACT) score, when IQ was used as a covariate; however, no significant group differences remained when ACT score was used as a covariate. More than half of the 126 petition and nonpetition students did not meet a minimum criterion for classification as learning disabled (LD), and more than half of both groups (54% and 63%, respectively) were not classified as LD before enrolling in college. Sixty percent of the petition students either had not taken an FL course in college or had achieved only grades of withdrawal before petitioning for substitution of the FL requirement. Implications addressed include petition students' persistence in fulfilling the FL requirement, students' use of instructional accommodations and services, criteria used to classify students as LD, use of the Modern Language Aptitude Test (MLAT), and why some students classified as LD pass FL courses and other students classified as LD do not.

Attention-deficit/hyperactivity disorder (ADHD) was previously believed to be a disorder of childhood, with symptoms attenuating at the onset of puberty. Follow-up studies, however, suggest that the majority of children with ADHD continue to manifest symptoms into adulthood. Although the inattention components associated with ADHD persist into adulthood, the nature of the hyperactivity component is less well understood. For example, according to criteria established by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, hyperactivity in adolescents and adults may be limited to subjective feelings of restlessness. Recent studies with adults with ADHD have also reported that mental restlessness is commonly reported by individuals with the disorder. To better understand this characteristic of ADHD, the Internal Restlessness Scale (IRS) was developed. The results of the IRS suggest that (a) college students with ADHD report significantly higher ratings of internal restlessness than college students without ADHD, and (b) the IRS appears to have adequate test—retest reliability and a four-factor structure. Implications and suggestions for future research are discussed.
Memory for Everyday Information in Students with Learning Disabilities

Published: December 2007

This study compared students with and without learning disabilities (LD) on their recall of academic information and information encountered in the students' everyday lives. The academic recall measures included a sentence listening span test, a rhyming words working memory test, and a visual matrix working memory task. Students' cued recall of all the tasks was also measured. The everyday working memory tasks included a dance episode event recall test; a library procedure recall test; and recall tests of commonly found objects, such as a coin, a telephone, and a McDonald's™ sign. Compared to students without LD, students with LD performed poorly on both the academic recall tasks and the everyday recall tasks. These results support the notion that some students with LD may have working memory problems that affect their performance on tasks other than reading. The results of the cued recall showed that the availability of cues significantly decreased the ability group differences on many of the academic and everyday tasks. This result replicates prior research findings that students with LD do not use retrieval strategies effectively and that some students with LD may have a production deficiency that affects their retrieval of previously encoded information.

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.
The Role of IQ in a Component Model of Reading

The purpose of this study was to test the role of visual processing speed and IQ in a model of reading. This study investigated whether the processes involved in reading differ between a group of children with and a group without reading disability. These two groups of children completed tests of reading comprehension, listening comprehension, decoding, processing speed, and intelligence. The results indicated that processing speed explains a significant amount of variance in reading comprehension over that accounted for by the simple view of reading. Also, IQ accounts for a significant amount of variance in reading over that accounted for by the simple view of reading and processing speed. Path analyses indicated that the effect of IQ on reading is partially mediated by decoding in the children with reading disability. The results point to the importance of the role of IQ in predicting reading comprehension.
