Variables influencing phonemic discrimination performance in normal and learning-disabled children.

Twenty-five learning-disabled and 25 normal first-grade-age children took a phonemic discrimination test that manipulated word-pairs systematically according to degree of phonetic difference, position of phoneme contrast, and lexical familiarity. Results indicated that (1) the significantly lower performance of the learning-disabled to children as a group was due to the impaired performance by a small subgroup, (2) all three stimulus variables had significant effects on performance, (3) all combinations of stimulus variables interacted significantly, and (4) discrimination performance did not correlate with measures of receptive vocabulary or reading achievement for either group.

Developmental psychiatry--insights from learning disability.

BACKGROUND: The Blake Marsh lecture, an annual lecture on learning disability, was endowed in 1963 in memory of Dr Blake Marsh, the former medical superintendent of Bromham House Colony in Bedford. The first lecture was given in 1967. AIMS: To review the speciality of the psychiatry of learning disability and how it is currently practised in the UK. METHOD: Clinical, service, research and educational issues in learning disability psychiatry are reviewed and illustrated. RESULTS: Key issues which emerge in all four areas include the importance of communication skills, consultation with users and carers, professional education and partnership. CONCLUSIONS: The psychiatry of learning disability is a complex, varied and stimulating branch of psychiatry with a strong developmental focus.

Effectiveness of aides in a perceptual motor training program for children with learning disabilities.

A program for children with learning disabilities associated with perceptual deficits was designed that included elements of gross and fine motor coordination, visual and somatosensory perceptual training, dance, art, music and language. The effectiveness of nonprofessional "perceptual-aides," who were trained in this program, was evaluated. Twenty-eight children with learning disabilities associated with perceptual deficits were treated by occupational, physical, recreational and language therapists; and 27 similarly involved children were treated by two aides, under supervision, after training by therapists. Treatment in both groups was for four hours weekly over a four to seven month period. There was significant improvement in motor skills, visual and somatosensory perception, language and educational skills in the two programs. Although there was no significant difference between the two groups, there was a slight advantage to the aide program. The cost of the aide program was 10 percent higher than the therapist program during the first year, but 22 percent lower than the therapist program during the second year.

Nationwide survey of postsecondary education services for students with learning disabilities.

Postsecondary services for students with learning disabilities vary a great deal from campus to campus, and published guides to postsecondary education services are often inaccurate and incomplete. A nationwide survey was conducted to investigate student service provisions in 2-year colleges and 4-year colleges and universities. The purpose of the study was to identify and catalog postsecondary education service goals and options for students with learning disabilities, and to determine differences between the goals service providers have for these students and services actually provided. The findings and their implications for service providers at both high school and college levels are discussed.

The relationship between occupational therapy and physical therapy test scores in children with learning disabilities.

Twenty-seven children with learning disabilities associated with perceptual deficits were studied in order to determine what relationship might exist between occupational therapy and physical therapy test scores. Intercorrelations were computed and multivariate models were developed for the occupational therapy test items. Numerous positive relationships were demonstrated between the two groups of test items, consistent with previous clinical and experimental data. One test, however, did not duplicate the other, and both are essential in the evaluation of the learning-disabled child with perceptual deficits. Negative correlations also emerged, which might have been caused by compensation for deficits.

A Canadian perspective on learning disabilities.

Canadian practice and research with children and adults with learning disabilities are described and analyzed. After an examination of the historical basis for current practice, the societal and cultural factors affecting education of children with learning disabilities, services for adults, and research are discussed. It was found that policy and legislation regarding special education vary considerably from province to province, and identification practices and service delivery models vary even within provinces. The fact that Canada has two official languages (English and French), a large multicultural community, and a Native population with special needs often arising from poverty has an impact on the education of children with learning disabilities and on sample description in research. Although school-age children are relatively well served, services for preschool children and adults with learning disabilities are minimal. The positive features of Canadian service delivery are that most programs are publicly funded, decision making tends to be nonadversarial and collaborative, and the needs of the whole child are typically considered.

Syntactic decoding times of learning disabled children.

Syntactic decoding reaction times of 20 learning disabled children comprising two groups of subjects (mean age of 8 and 13 yr., respectively) were compared to the responses of normal controls matched for age and sex. An analysis of variance procedure showed that the learning disabled children and their normal peers did not differ significantly in responses to the experimental stimuli. This held true regardless of linguistic complexity, suggesting that delays in processing elementary syntactic constructions are not a concomitant of learning disabilities.

An hypothesis regarding the commonality of right-hemisphere involvement in learning disability, attentional disorder, and childhood major depressive disorder.

Learning disability, attentional disorder, and childhood major depression are frequent clinical diagnoses for children who show behavioral disturbances and impaired school performance. We suggest that all three of these conditions may be associated with dysfunction of the right cerebral hemisphere. Anatomical disturbance of right-hemisphere function is often associated with learning disability or attentional deficits. The physiological disturbance of right-hemisphere function by a major depressive episode may produce or exacerbate learning disability or attentional disorder.

The effects of hemispatial and asymmetrically focused attention on dichotic listening with normal and learning-disabled children.

The effects of hemispatial and focused attention were examined with 50 normal and learning-disabled children to determine the extent of these two attentional strategies influenced perceptual laterality as reflected by the dichotic listening right-ear advantage (REA). Twenty-five normal children (8 females, 17 males, mean age 9.10 yr) matched with 25 learning-disabled children (8 females, 17 males, mean age 10.1 yr) were administered a dichotic consonant-vowel (CV) and consonant-vowel-consonant (CVC) syllable task. The two types of stimuli were compared across focused attention (free report, focused left, focused right) and hemispatial (central, left hemispace, right hemispace) conditions implemented independently and in systematic combinations. A four-factorial analysis of variance (groups x stimuli x conditions x ears) resulted in a significant REA for normal children across all attentional conditions whereas learning-disabled did not produce a consistent REA across all attentional conditions, and in several instances, produced equivalent left and right hemisphere processing. Right hemispatial orientation increased the magnitude of the REA (i.e., left hemisphere processing) for both groups, whereas left hemispatial orientation increased the magnitude of the left ear report (i.e., right hemisphere processing) only in learning-disabled subjects. Focused attention to the right ear also increased left hemisphere efficiency for both groups of children; however, focused attention to the left ear produced symmetrical functioning by learning-disabled subjects. Congruent combinations of focused attention and hemispatial orientation were not found to enhance the REA beyond its magnitude when each strategy was assessed independently. When focused attention and hemispatial conditions were employed in opposing directions, normal children were more susceptible to the "rightward" direction regardless of the strategy whereas learning-disabled subjects were more susceptible to the "verbal" nature of the strategy. Higher overall processing performance was exhibited for CVC stimuli when compared to CV stimuli. These findings lend support to the hypothesis that hemispatial and asymmetrically focused attention strategies interact with structural mechanisms in producing the observed REA in dichotic listening and do so differentially for normal and learning-disabled children.

American Academy of Pediatrics Committee on Children with Disabilities: American Association for Pediatric Ophthalmology and Strabismus, and American Academy of Ophthalmology: Learning disabilities, dyslexia, and vision.

Dyslexia and other related learning disabilities are serious problems. The American Academy of Pediatrics, through its Committee on Children with Disabilities and the Section on Ophthalmology, the American Academy of Ophthalmology, and the American Association for Pediatric Ophthalmology and Strabismus strongly support the need for early diagnosis and educational remediation. There is no known eye or visual cause for dyslexia and learning disabilities, and no effective visual treatment. Multidisciplinary evaluation and management must be based on proven procedures demonstrated by valid research.

Salivary testosterone in children with and without learning disabilities.

Previous studies have indicated that the sex steroids have organizational effects upon neural tissue and that abnormal secretion during development may lead to functional anomalies. In this study, we explore the possibility of prepubertal steroid hormone involvement in the etiology of learning disabilities. Salivary testosterone levels in 264 children without learning disabilities (133 males, 131 females) were measured and compared to that in 32 children with learning disabilities (25 males, 7 females). The presence of learning disabilities was significantly associated with higher salivary testosterone. Data from equivalent samples of learning-disabled and control subjects also were compared separately because of disparities in sample size and variable distribution in the total group analysis. A 32-member sample of nonlearning-disabled children was created by randomly selecting individuals who exactly matched the age, race, and sex characteristics of the learning-disabled group. The matched analysis further substantiated the association between testosterone secretion and learning disabilities. Thus, it is possible that some learning disabilities may be associated in part with abnormal testosterone levels.

Attitudes of general practitioners to caring for people with learning disability.

BACKGROUND: The views of general practitioners on their increasing role in caring for people with learning disability in the community are not known. AIM: A study was carried out to assess the views of general practitioners with regard to providing routine care, organizing health promotion and specific health checks for people with learning disability and the role of specialists. METHOD: A postal questionnaire was sent to all 242 general practitioners in Gwent, south Wales. Participants had to mark their level of agreement with 20 attitude statements regarding learning disability. RESULTS: A total of 126 general practitioners (52%) responded. Respondents generally agreed that general practitioners were responsible for the medical care of people with learning disability. Respondents tended to be opposed to providing regular structured health promotion for people with learning disability, such as annual health checks and assessing hearing and eyesight. Specialist services were generally valued by respondents. CONCLUSION: General practitioners largely accepted their role as primary health care providers for people with learning disability. In contrast, their role as providers of health promotion for this patient group was not generally accepted. Further research into the appropriateness and opportunity costs of health screening for people with learning disability is needed.

Mathematics education and students with learning disabilities: introduction to the special series.

The prevalence of students with mathematics learning disabilities has triggered an interest among special education researchers and practitioners in developing an understanding of the needs of this group of students, and in identifying effective instructional programming to foster their mathematical performance during the school years and into adulthood. Research into the characteristics of students with mathematics learning disabilities is being approached from different perspectives, including developmental, neurological and neuropsychological, and educational. This diversity helps us develop a broader understanding of students' learning needs and difficulties. Special education assessment practices encompass a variety of approaches, including norm-referenced, criterion-referenced, and nonstandardized procedures, depending on the specific assessment questions professionals seek to answer. Students' mathematical knowledge and conceptual understanding must be examined to determine their strengths and weaknesses, curriculum-based progress, and use of cognitive strategies to arrive at mathematical solutions. Research findings have identified empirically validated interventions for teaching mathematics curricula to students with mathematics learning disabilities. Research studies have been grounded in behavioral theory and cognitive psychology, with an emergent interest in the constructivist approach. Although research studies have focused primarily on computational performance, more work is being conducted in the areas of story-problem solving and technology. These areas as well as other math curricular skills require further study. Additionally, the needs of adults with math LD have spurred educators to examine the elementary and secondary math curricula and determine ways to infuse them with life skills instruction accordingly. As the field of mathematics special education continues to evolve, special educators must remain cognizant of the developments in and influences on the field of mathematics education. Reform efforts have shaped the field significantly since the 1950s, contributing to the curriculum offered in mathematics textbooks and the pedagogical practices taught in higher education courses. Mathematics educators continue to search for a better understanding of how children learn mathematics; this process is shaped by the prevailing theoretical orientations and research methodologies. This special series in mathematics special education provides readers with information about the characteristics of students with mathematics learning disabilities, assessment procedures, mathematics programming, teacher preparation, and future directions for the field. The series originated as a result of discussions with Dr. Lee Wiederholt and Dr. Judith K. Voress, who saw a need for the compilation of recent research and best practices in mathematics special education. I thank them for their support of and thoughtful insights about the development of this series. I also appreciate the support of Dr. George Hynd and his editorial assistant, Kathryn Black, in finalizing the details for publication. Finally, I am most appreciative of the authors' contributions to this series; their work continues to significantly influence the development of the field of mathematics special education and programming for students with mathematics learning disabilities.

Learning disabled boys' performance and self-assessments on physical fitness tests.

30 learning disabled boys drawn from a segregated private school for learning disabled children and 22 from a public school mainstream program and 22 nondisabled boys performed two physical fitness tests, sit-ups and shuttle run in one of two conditions. While normal achievers performed significantly better on one of the tests, there were no differences between the two samples of learning disabled youngsters. However, students' comparisons of their performance with classmates' indicated that learning disabled youngsters in the private school ranked themselves more favorably than those in mainstream classrooms.

Dysrationalia: a new specific learning disability.

The concept of selective deficit is the foundation of most conceptual definitions of learning disability. Such definitions have tended to implicate the construct of intelligence in the conceptualization of learning disability and have led to the use of IQ test scores to operationalize the notion of aptitude-achievement discrepancy. The learning disabilities field is only beginning to grapple with the implications of its reliance on the concept of psychometrically defined intelligence. For example, discrepancy-based definitions of learning disabilities guarantee that such disabilities will become more or less prevalent depending on the comprehensiveness of the set of skills assessed on IQ tests. Unlike the vernacular concept of intelligence--which is quite broad--psychometric operationalizations reflect only a thin slice of the mental domain that might be considered cognitive. Thus, it is possible that we have not exhausted the potential set of discrepancy-based disabilities. As a demonstration proof, a new discrepancy-based disability category is proposed and defended in this paper. The disability is one that may force more careful consideration of the role that intelligence plays in conceptual and operational definitions of learning disabilities.

Podiatric disorders among children with Down syndrome and learning disability.

This study investigated podiatric pathology in seven- to 14-year-old children with Down syndrome (DS) and non-Down syndrome learning-disabled and non-learning-disabled age-matched controls. Several conditions, including pes planus, fissures, split toenails, increased plantar flexed first ray and a wide hallucal cleft were found to be more common in the DS group. Pes cavus and foot rigidity were more common in the non-DS learning-disabled group. In all groups the majority of children wore laced shoes, which were most ill-fitting among children with a learning disability. Approximately one-third in each group had abnormal foot-pressure prints. Greater care and professional awareness of podiatric pathology in children with learning disability is recommended.

A naturalistic study of the use of vigabatrin, lamotrigine and gabapentin in adults with learning disabilities.

Epilepsy is a common condition in people with learning disabilities with many patients continuing to suffer from seizures despite antiepileptic drug (AED) treatment. Although the advent of newer AEDs offers hope for better treatment, there is a need to compare the efficacy of each new AED in adults with both drug-resistant epilepsy and learning disabilities. This retrospective casenote study involves the analysis of the outcome for those adults with learning disabilities treated with either vigabatrin, lamotrigine or gabapentin. The information obtained from the casenote analysis was used to both compare the efficacies of the three drugs and also the side-effects and drop-out rates, including reasons for drop-out. The total number of patients involved was 51 who underwent 71 treatment episodes. All three AEDs had similar efficacies. Although vigabatrin was found to be associated with a higher incidence of behaviour problems, behaviour problems occurred with the other drugs as well. Lamotrigine caused increased seizures in 24% of patients, especially when prescribed at a higher dose. Gabapentin appeared to be associated with fewer serious side-effects.

Psychiatric symptoms in adults with learning disability and challenging behaviour.

BACKGROUND: In people with learning disability one of the most frequent reasons for psychiatric referral is challenging behaviour. AIMS: To determine what proportion of people with challenging behaviour actually have psychiatric symptoms. METHOD: Using an instrument specifically designed for use by informants, a sample of 320 people with administratively defined learning disability, with and without challenging behaviour, was surveyed for the presence of psychiatric symptoms. RESULTS: Increasing severity of challenging behaviour was associated with increased prevalence of psychiatric symptoms, depression showing the most marked association. Anxiety symptoms were associated with the presence of self-injurious behaviour. CONCLUSIONS: There is clearly the potential for reducing challenging behaviour by improved identification and treatment of coexisting psychiatric disorders. The possibility of modifying diagnostic criteria for depression in people with learning disability, by including aspects of challenging behaviour, merits attention.
