Pointing to the way ahead. Health education for people with learning disabilities.

People with learning disabilities have a right to health education, and nurses working with them have ample opportunities to fulfil this role. Health education must cater for individual clients' needs, and be presented in a style and language they can easily understand. Effective communication partly depends on being able to emphasize with clients; it is important to appreciate that clients are responsible for their actions.

Word identification performance in the presence of competing speech and noise in learning disabled adults.

Eight learning disabled (LD) adults and eight control subjects identified monosyllabic words presented simultaneously in the presence of speech spectrum noise and three types of linguistic maskers. The performance of LD subjects was poorer than that of the control subjects under each masking condition. Word identification was poorest in the presence of speech noise for both groups. No difference in performance was seen as a function of the linguistic content of the competing speech maskers. These results suggest that LD subjects present greater susceptibility to acoustic masking relative to control subjects and may support the view that auditory-language deficits observed in LD individuals may be secondary to an underlying acoustic-phonetic disorder rather than a central phonologic disorder. LD college students may experience S/N ratios in the classroom that perpetuate or exacerbate their listening problems.

Storage-retrieval processes of normal and learning-disabled children: a stages-of-learning analysis of picture-word effects.

Previous research comparing acquisition performance of learning-disabled and normally achieving children has led to the suggestion that the locus of memory differences lies in either the storage or retrieval components of recall. In this paper we report a free-recall experiment in which a new stages-of-learning model was used to examine the effects of a picture-word manipulation on storage and retrieval differences between nondisabled and disabled grade 2 and 6 children. Although the results of this experiment were consistent with the idea that disabled students are poorer at memory tasks than nondisabled students, the stages-of-learning analysis provided information regarding the precise locus of the deficiencies. Specifically, although disabled and nondisabled children benefited from the presentation of information in pictorial format, normally achieving children were consistently better than their learning-disabled counterparts at storing and learning to retrieve both pictures and words. From a developmental standpoint, the most important finding was that while differences between learning-disabled and normally achieving students at storage remained age invariant, differences in learning to retrieve increased with age. As it turned out, however, differences between disabled and nondisabled children were absent when it came to retaining traces once they had been stored in memory and in retrieval performance between the time a trace was stored and retrieval learning was complete. These results are consistent with previous research in which it has been shown that the ability to learn how to reliably retrieve information that has been stored in memory develops more slowly for disabled than nondisabled children.

Sleeping and dreams in learning-disabled boys.

Ten learning-disabled (LD) boys were compared with eight control boys. The boys with learning difficulties reported shorter sleep latency but more frequent awakenings, longer nocturnal sleep, and increased complaints of daytime sleepiness than the controls. The dreams of the LD boys were less bizarre than those of the controls, and the LD boys used fewer words to describe their dreams. The findings may reflect a functional relation between experienced sleep-related difficulties, some components of dreams, and learning disabilities in school children.

Cortical dysfunction as an aetiological factor in learning disability.

This study examines the relationship between learning disability, EEG changes, and events in the life history of the individual child which could cause cortical damage or dysfunction. One hundred children with learning disability were compared with 100 age- and sex-matched normal children identified by random selection. Each child underwent routine EEG studies. Abnormalities were detected in 71 of the learning-disabled group and in 29 of the controls. The incidence of abnormal pregnancy was 31% in children with learning disability and 10% in controls. Neonatal complications occurred in 29 learning-disabled children as opposed to 13 controls. Seventeen learning-disabled children had experienced seizures and 5 had a history of meningitis; comparable figures in the control series were 7 and 2 respectively. Nine learning-disabled children had a history of severe illness as opposed to 3 children in the control series. The results of this study indicate that a significant relationship exists between learning disability and a variety of circumstances associated with insults to the immature brain. These insults may account for the cortical dysfunction suggested by psychometric and EEG studies.

Learning disabilities and vocational rehabilitation.

Students with learning disabilities have received services in special education programs for many years. Unfortunately, many of these students continue to need services after they exit high schools. Vocational rehabilitation has begun to provide services for young adults with learning disabilities; however, there continues to be a discrepancy between the number of adults with learning disabilities who need vocational rehabilitation services and those who are receiving them. This article describes the definitions and eligibility criteria used by vocational rehabilitation agencies to serve adults with learning disabilities. By understanding the vocational rehabilitation system, teachers, it is hoped, will be better able to access these services for their students with learning disabilities.

Psychological and family problems associated with learning disabilities: assessment and intervention.

Learning disabilities not only interfere with academic tasks; they interfere also with all stages of psychosocial development as well as with peer and family interactions. It is not uncommon, therefore, for children and adolescents with learning disabilities to have psychological, peer, and family problems. These secondary difficulties must be recognized, correctly diagnosed, and treated.

Postsecondary education for students with learning disabilities.

Increasingly, students with learning disabilities are attending community colleges and traditional 4-year colleges and universities. This article presents the results of a review of the literature on services available or recommended for students with learning disabilities. The results suggest that postsecondary institutions have begun to provide a wide array of services to these students. There is little empirical evidence, however, on the effectiveness of those services. An agenda for future research is also discussed.

Semantic and visual memory codes in learning disabled readers.

Two experiments investigated whether learning disabled readers' impaired recall is due to multiple coding deficiencies. In Experiment 1, learning disabled and skilled readers viewed nonsense pictures without names or with either relevant or irrelevant names with respect to the distinctive characteristics of the picture. Both types of names improved recall of nondisabled readers, while learning disabled readers exhibited better recall for unnamed pictures. No significant difference in recall was found between name training (relevant, irrelevant) conditions within reading groups. In Experiment 2, both reading groups participated in recall training for complex visual forms labeled with unrelated words, hierarchically related words, or without labels. A subsequent reproduction transfer task showed a facilitation in performance in skilled readers due to labeling, with learning disabled readers exhibiting better reproduction for unnamed pictures. Measures of output organization (clustering) indicated that recall is related to the development of superordinate categories. The results suggest that learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes.

Nursing students with learning disabilities: guidelines for fostering success.

Learning disabilities can be devastating for the nursing student, interfering with academic performance and with success on the NCLEX-RN. Within the past five to ten years, college educators are seeing an increasing number of students with learning disabilities diagnosed in the 1970s, who are now ready for higher education. This phenomenon is becoming apparent as well in schools of nursing in the United States. This article describes the problem, gives characteristics by which the student with a learning disability can be identified, and suggests methods for assisting the student to achieve success in school and on the national licensing examination following graduation.

Auditory, visual, and multisensory nonverbal social perception in adolescents with and without learning disabilities.

Adolescents with and without learning disabilities (14, 16, and 18 years old) were tested to determine whether they differed in auditory, visual, and/or multisensory (combined auditory/visual) social perception abilities. Differences between the two groups in growth of auditory, visual, and multisensory social-perception abilities were also measured. Results of the data analyses revealed that adolescents with learning disabilities were not as adept at understanding nonverbal social information regardless of whether the information was visual or multisensory in nature. Further, nonverbal social-perception ability for both visual and multisensory information improved with increasing age for both populations. Finally, adolescents with learning disabilities continued to demonstrate comparatively poorer social-perception abilities through the 18-year level.

Information processed from brief visual displays by learning-disabled boys.

The spans of apprehension of learning-disabled and normal boys were compared by means of a forced-choice letter-recognition task involving tachistoscopic exposures of letter displays. This task provides an estimate of the span that is relatively insensitive to memory or motivational influences. In Experiment 1, the spans of learning-disabled and normal boys were compared under 4 information conditions: with no noise letters present or with 2, 4, or 8 noise letters present. Experiments 2-4 examined 3 possible interpretations of the deficit in the span of apprehension observed for learning-disabled boys in Experiment 1. In Experiment 2, the possibility that the noise letters were more distracting for learning-disabled boys was examined by varying the amount of physical similarity and redundancy between the signal and noise letters. In Experiment 3, the possibility that the visual afterimage of the letter displays faded more rapidly for the learning-disabled boys was examined. In Experiment 4, the possibility that the learning-disabled boys were slower to pick up information from the decaying afterimages was examined. The results of these three experiments indicated that the decreased spans of apprehension observed for the learning-disabled boys in Experiment 1 resulted either from greater distractiveness or from the slower pickup of information, or both. The implications for visual training are discussed.

The relationship between learning disability, emotional disorders, and neuropsychology; some results and observations.

Emotional disorders may precede learning disabilities, follow learning disabilities, or occur at the same time. This paper discusses evidence supporting each of these hypotheses, focussing on the possibility that both learning disabilities and emotional disorders, or at least some subforms of them, may have a common origin in neurological dysfunction. A model of interaction of the many factors involved in both the development and the persistence across age for both learning disabilities and emotional disorders is presented and avenues of research are discussed. Data from a 15-year follow-up study which illustrate some of these complex relationships are presented.

Signs of neurobehavioral dysfunction in a sample of learning disabled children: stability and concurrent validity.

Of 270 learning disabled children with average intelligence and significant delays in reading comprehension a sample of 37 were evaluated for signs of neurobehavioral dysfunction. All such signs--primitive reflexes, equilibrium reactions, and postrotary nystagmus--were reliably assessed. A subsample of 19 children was compared with developmentally normal and mentally retarded samples for the occurrence of tonic neck reflexes and equilibrium reactions. The learning disabled children consistently showed deviancies like those of the retarded children; both of these groups differed from the normal children on most measures. These deviant responses persisted over a 9-mo. period for the learning disabled group. Compared with norms, the total learning disabled sample displayed hyponystagmus, and this depressed nystagmus persisted for 11 mo. Results are discussed in relation to the lack of correlation among the various signs of neurobehavioral dysfunction in the learning disabled children.

The relationship between visual-perceptual motor abilities and clumsiness in children with and without learning disabilities.

One visual-perceptual test, four visual-motor tests, and a test of motor impairment were administered to 22 children with learning disabilities and 22 children without learning disabilities, aged 5 to 8 years. The children with learning disabilities were divided into two groups--"clumsy" and "nonclumsy"--based on their scores on the motor impairment test. It was hypothesized that the clumsy children with learning disabilities would score significantly lower on visual-perceptual and visual-motor tests than the nonclumsy children with learning disabilities who, in turn, would score significantly lower than the children without learning disabilities. It was further hypothesized that there would be a significant correlation between the degree of clumsiness and the degree of visual-perceptual and visual-motor deficit. Analysis of the data indicated that, as expected, the clumsy children with learning disabilities scored significantly lower than the children without learning disabilities (the control group). There was no significant difference between the clumsy and nonclumsy children with learning disabilities or between the nonclumsy children with learning disabilities and the control group. Degree of clumsiness significantly correlated with scores on four of five tests. Results are discussed in terms of subtypes of learning disabilities and sample size.

A childhood learning disability that predisposes those afflicted to adolescent and adult depression and suicide risk.

A particular subtype of learning disability (nonverbal learning disability) is described. This subtype of individuals with learning disability is seen to be at particular risk for depression and suicide. The origins of the study of this subtype of learning disability, its incidence in various forms of neurological disease, disorder, and dysfunction, and its behavioral and socioemotional manifestations (including its association with significant internalized forms of psychopathology) are described. A case history of a young woman who manifests this disability and who has attempted suicide on three occasions is also presented.
