Behavioural treatment of urinary incontinence and encopresis in children with learning disabilities: transfer of stimulus control.

Urinary and faecal incontinence present a considerable problem in people with learning disabilities, despite the general effectiveness of behavioural techniques in continence training. Children with learning disabilities and obsessional behaviour may be particularly resistant to toilet training, even where relatively cognitively able, and often despite a substantial degree of control over their eliminatory functions. Their resistance may be more appropriately regarded as a challenging behaviour and their incontinence better explained by factors other than a simple failure to learn. A 'stimulus-control' hypothesis proposes that the child's nappy (diaper)/potty/underwear has developed strong stimulus control over the elimination response. This report describes three case studies in which treatment-resistant children, aged between 8 and 12 years, with mild or moderate learning disabilities, were successfully treated for nappy-dependent nocturnal encopresis or diurnal urinary incontinence. The children were routine case referrals for whom previous attempts to train bowel or bladder control had failed. Behavioural techniques, such as 'shaping' (gradually increasing the proximity to the toilet), 'fading' (reducing the presence of the nappy), and rewards for eliminating, effected successful transfer of stimulus control over elimination from nappy to toilet. Treatment times varied, depending on the degree of the child's obsession and resistance to change.

Neuropsychological stability and prognosis of subgroups of children with learning disabilities.

A sample of 74 Finnish children with mild learning disabilities (LD) and 57 controls was followed from the third grade (Study 1) to the sixth grade (Study 2). In the initial study, the sample had been grouped into five valid subgroups (Normal, General Language, Visuo-Motor, General Deficiency, Naming) utilizing a cluster analysis. In both studies a battery of 12 neuropsychological, reading, and writing tests was administered, and teacher ratings were obtained. The results indicated that the general neuropsychological profiles of the subgroups were maintained, but some changes, consistent with the progress in reading, were noted. The developmental rate of some neuropsychological functions from Study 1 to Study 2 in the subgroups of children with learning disabilities more closely approached that of the Normal subgroup. At follow-up, 64% of the original LD sample continued to have marked reading and/or writing problems. The Naming subgroup had a more unfavorable prognosis than the other subgroups, especially in reading, and the General Deficiency subgroup in writing (spelling), respectively. Some possibilities for using the results to improve remedial teaching are discussed.

Involving users with learning difficulties in health improvement: lessons from inclusive learning disability research.

In this paper the author considers the lessons to be drawn from what is termed "inclusive" learning disability research for user involvement around health improvement. Inclusive learning disability research refers to research where people with learning difficulties (intellectual disability) are involved as active participants, as opposed to passive subjects. There is by now a considerable body of such research, developed over the past 25 years. From the review, the author draws attention to areas which can inform practice in involvement of users in a way that adds value.

Conductive hearing loss in autistic, learning-disabled, and normal children.

Katz (1978) has suggested that mild, fluctuating conductive hearing loss due to middle-ear anomalies may account for the language and attention problems of learning-disabled children. His position was extended here to include autism. Normal, learning-disabled, and autistic children received repeated impedance measures over 5 weeks. A repeated-measures ANOVA of central tendency and variability values led to the conclusions that (1) fluctuating, negative middle-ear pressure greater than normal characterizes both autistic and learning-disabled children, (2) the negative pressure is greater in autistic than in learning-disabled children, and (3) the condition is typically bilateral for autistic children.

The utility of math difficulties, internalized psychopathology, and visual-spatial deficits to identify children with the nonverbal learning disability syndrome: evidence for a visualspatial disability.

This study examined the criteria currently employed to identify children with the nonverbal learning disability syndrome (NVLD). The most widely accepted definition of NVLD relies on deficits in visual-spatial-organizational, tactile-perceptual, psychomotor, and nonverbal problem-solving skills. These deficits are believed to coexist with strengths in rote verbal learning, phoneme-grapheme matching, verbal output, and verbal classification. The combination of these assets and deficits has been hypothesized to lead to psychosocial and academic problems, including difficulties with mathematics and increased rates of psychopathology. This study compared performance of three groups of children: those with NVLD, those with verbal learning disabilities (VLD), and controls. The results show that the criteria currently employed to identify children with NVLD may not adequately differentiate them. In contrast to previous findings, the study reveals that children with NVLD can demonstrate good math abilities when performing certain types of math tasks, especially those that draw on their robust verbal skills. Also in contrast to most previous findings, in this study children with NVLD (and normal controls) demonstrated lower rates of psychopathology than children with VLD. Finally, for children with NVLD it appears that their visual-perceptual deficits may include a primary deficit in locating objects in space. Based in part on the findings of this study, it may be helpful for diagnostic and treatment purposes to reserve the term Nonverbal Learning Disability for children whose visual-spatial deficits are primary and severe enough to affect academic performance in subjects such as written mathematics. Given the integral nature of social relations in children's lives, a separate category (e.g., social processing disorder) could be created for children whose social skills deficits are primary and impair their social interactions. A broader nonverbal learning model or syndrome, as conceptualized by Rourke (1995), could be retained for describing a broader constellation of assets and deficits across disease types.

An evaluation of the efficacy of training people with learning disabilities in a virtual environment.

PURPOSE: To evaluate the efficacy of using a virtual kitchen for vocational training of people with learning disabilities. METHOD: Twenty four catering students with learning disabilities participated in the study. Half the students were currently being trained in the kitchen on which the virtual kitchen was modelled but the remaining students were unfamiliar with this kitchen. Students were first pre-tested on four food preparation tasks and identification of 12 hazards in their own training kitchens. They were subsequently trained on one food preparation task and three hazards in their own training kitchens, one food preparation task and three hazards in the virtual kitchen, and one food preparation task and three hazards in specially designed workbooks. They were then retested in their own training kitchens on all the food preparation tasks and all the hazards. RESULTS: Virtual training was found to be as beneficial as real training and more beneficial than workbook and no training in the food preparation tasks. However, virtual, real and workbook training were found to be equally beneficial in the hazard identification task. Students who were unfamiliar with the kitchen on which the virtual kitchen was modelled benefited from virtual training to the same extent as students who were familiar with the kitchen. CONCLUSIONS: Vocational students with learning disabilities were able to use the virtual environment and were motivated to learn using this training method. Depending on the task being trained, virtual training had a more beneficial effect on real task performance than workbook training, even when the virtual kitchen was not modelled on the real training kitchen.

How tutors assist adults with learning disabilities to use virtual environments.

PURPOSE: To describe strategies used by tutors teaching adults with learning disabilities to use desktop virtual environments and to investigate their effectiveness by examining changes over time in tutor and learner behaviour. METHOD: Twenty adults with learning disabilities spent 12 sessions with one of four non-disabled tutors learning to use desktop virtual environments designed to teach independent living skills. Sessions were recorded on videotape, categories of behaviour were described and tapes analysed for frequency of tutor behaviours and goals achieved by learners. RESULTS: Tutor strategies were described in terms of whether they aimed to help the learner master the interaction devices or to navigate and achieve goals in the virtual environments and how directive they were. There were some differences between tutors but this did not relate to whether tutors were experienced users themselves of the environments or were initially unfamiliar with them. Goal achievement was maintained at a constant level while help with the interaction devices and specific information about the environment decreased over repeated sessions. Rates of non-specific information did not change. CONCLUSIONS: Pretraining with the interaction devices would free both tutor and learner to concentrate on achieving goals in the environments. Much of the specific help given by the tutor could be incorporated into the software.

The learning-disabled juvenile delinquent: a case for early intervention of perceptually handicapped children.

The relationship between learning disabilities and juvenile delinquency is examined from an historical perspective as well as from the author's investigations. The majority of studies suggest that learning disabilities occur with significant frequency in delinquent populations. Perceptual disorders can be a significant cause of academic underachievement and poor social adaptation among youthful offenders. Preliminary results of an investigation of the learning-disabled delinquent confirm that the perceptually handicapped child is at high risk for developing these behavioral problems. As one of the first professionals who may be involved in the evaluation and treatment of the perceptually handicapped child, the occupational therapist is a key person in effecting early intervention. Early intervention is considered of prime importance as one preventive measure of juvenile delinquency.

Self-perceptions of first- and second-grade children with learning disabilities.

The present study addressed the question of the effects of developmental positive bias and repeated experiences of failure on the self-perception of mainstreamed first-and second-grade Israeli children with learning disabilities. The self-perceptions of 44 children with learning disabilities and their 36 nondisabled classmates were assessed. In addition, teachers' evaluations and objective measures of cognitive performance and social acceptance were gathered. The children with learning disabilities were found to have a greater positive bias and lower self-perception in the cognitive competence domain than their normally achieving peers. Self-perceptions of peer acceptance among children with learning disabilities are similar to their normally achieving peers' self-perceptions, in spite of their significantly lower sociometric ratings and teacher evaluations in the social domain. These findings are analyzed in the context of the globality-specificity dimension of self-perceptions at the age level studied. The obtained pattern of self-perceptions is discussed in the light of the interrelationships between cognitive deficit and experimental factors among mainstreamed first- and second-grade children.

An exploratory investigation into the usability and usefulness of training people with learning disabilities in a virtual environment.

PURPOSE: Two studies sought to answer the following questions. Are people with learning disabilities capable of using a virtual environment? Are they motivated to learn using this training method? Do they show any benefit from using a virtual environment? Does any benefit transfer to improved real world performance? METHOD: In the first study, 30 students with learning disabilities were sequentially allocated to an active or a passive experimental group. Active participants explored a virtual bungalow searching for a toy car. Passive participants watched the exploration undertaken by the preceding active participant and searched for the toy car. All participants then performed spatial and object recognition tests of their knowledge of the virtual environment. In the second study, the errors of 45 participants on a real steadiness tester task were noted before they were randomly allocated to three groups-a real training group, a virtual training group and a no training group. After training, the participants performed a second test trial on the real steadiness tester. RESULTS: The students were capable of using a virtual environment and were motivated to use this training method. Active exploration of a virtual environment was found to enhance their memory of the spatial layout of the bungalow but not their memory of the virtual objects. In the second study, virtual training was found to transfer to real task performance. CONCLUSIONS: These two laboratory-based studies provide answers to four important questions concerning virtual training of people with learning disabilities. Hopefully, the findings will encourage this training aid to be used more widely.

Research utilization and attitudes towards research among learning disability nurses in Northern Ireland.

Research utilization and attitudes towards research among learning disability nurses in Northern Ireland The current emphasis on evidence-based practice has focused attention once again on the research activities of health professionals in general and their research utilization in particular. While there has been a limited number of studies on research utilization in the United Kingdom, these have tended to concentrate on general nurses and midwives. Little is known about the research activities, research utilization and the attitudes to research of learning disability nurses. This paper reports on data from a survey of a convenience sample of 87 nurses from three learning disability hospitals in Northern Ireland. The results show that while these nurses generally held positive attitudes to research, a substantial minority (18.3%) believed that 'research is not relevant to the day to day work in nursing'. Only a quarter of the sample reported using research 'frequently/all the time' in their practice. The extent of research utilization among these disability nurses must be considerably improved if evidence-based practice is to become a reality in their field of nursing.

Visual and auditory selective attention and reflection-impulsivity in normal and learning-disabled boys at two age levels.

Selective attention to visual and auditory stimuli and reflection-impulsivity were studied in normal and learning-disabled 8- and 12-year-old boys. Multivariate analyses, followed by univariate and paired-comparison tests, indicated that the normal children increased in selective attention efficiency with age to both visual and auditory stimuli. Learning-disabled children increased in selective attention efficiency with age to auditory, but not to visual, stimuli. Both groups increased with age in reflection as measured by Kagan's Matching Familiar Figures Test (MFF). The 8-year-old learning-disabled children were more impulsive than the 8-year-old normals on MFF error scores, but not on MFF latency scores. No difference occurred between the 12-year-old learning-disabled and normal children on either MFF error or MFF latency scores. Correlations between the selective attention scores and MFF error and latency scores were not significant.

Classroom behavior of children and adolescents with learning disabilities: a meta-analysis.

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed.

Taurodontism and learning disabilities in patients with Klinefelter syndrome.

PURPOSE: The purpose of this descriptive clinical study was to determine the prevalence rates of taurodontism and learning disabilities in a sample of patients with Klinefelter syndrome. METHODS: Questionnaires and dental radiographs of Klinefelter syndrome patients were obtained and analyzed using previously published methods. Prevalence rates were determined for taurodontism and learning disabilities in the sample population and compared to the general population. Statistical analyses included a Fisher's exact 2-sided test to compare the prevalence rates to that found in the general population and subsequent determination of the positive predictive value. RESULTS: Taurodontism was found in 75% of the 24 participants. Eighty-three percent of the participants reported having a learning disability. These rates are significantly higher than the general population, as reported in the literature. CONCLUSIONS: The positive predictive value for Klinefelter syndrome, given a male patient with taurodontism and a learning disability, is 84%. In this case, the dentist should recommend karyotyping to the patient, parent, or physician. This demonstrates how important it is for dentists to understand and assist physicians in the diagnosis of genetic disorders.

The diagnostic value of cerebellar-vestibular tests in detecting learning disabilities, dyslexia, and attention deficit disorder.

Neurological and optokinetic measures of cerebellar-vestibular (CV) dysfunctioning were shown to be of significant diagnostic value in differentiating between learning disabled subjects and controls matched for chronological age, sex, handedness, IQ, and background (ns = 35). Although traditionally used electronystagmographic positional and caloric parameters were not similarly discriminating, quantitative measures of vertical nystagmus in various eyes-closed positions appeared to have diagnostic potential and were related significantly to such CV-determined neurological signs as positive monopedal Romberg. As a substantial majority of learning disabled (82.9%) evidenced ADD-like symptoms and since learning disabled subsamples with and without Attention Deficit Disorder (ADD) shared similar coexisting symptoms and CV signs, it appeared probable that learning disabilities and ADD were reflections of the same underlying CV determinants.

Self-concept and IQ as predictors of remedial success in children with learning disabilities.

Twenty-five children with learning disabilities (LD) in the auditory-linguistic realm participated in the present study over two academic years. The purpose of the experiment was to test whether IQ and self-concept were significant predictors of learning ability. IQ was found to have no relationship to the children's learning ability, whereas self-concept predicted patterns of successful achievement in spelling, arithmetic, and written language, but not in visual word recognition. The results were interpreted as support for the "specificity" presumption in LD, but also as support for the importance of self-concept as possibly a primary cause of academic underachievement. The paper develops a remedial model of LD that accounts both for the interplay of self-concept and cognition in learning and for the fundamental implications of the specificity principle.
