Computer-based reading and spelling practice for children with learning disabilities.

To examine the effects of computer-based reading and spelling practice on the development of reading and spelling skills, a pretest-training-posttest experiment was conducted in The Netherlands. Eleven girls and 17 boys with written language disorders (on the average, 9 years, 7 months old and performing 2 grades below age expectancy) practiced hard-to-read words under three conditions: reading from the computer screen, copying from the screen, and writing from memory after presentation on the screen. For all words, whole-word sound was available on call during practice. To assess learning effects, both a dictation and a read-aloud task were administered in which nonpracticed control words were also presented. During training, the computer kept record of several aspects of the pupils' learning behavior. It was found that copying words from the screen resulted in significantly fewer spelling errors on the posttest than writing words from memory, and that both forms of spelling practice led to fewer spelling errors than only reading words during practice. All three forms of practice improved to the same degree both the accuracy and fluency of reading the practiced words aloud. The way in which spelling and reading practice, in combination with speech feedback, support the development of phonological skills in children with written language disorders is highlighted in the discussion.     

Speaking to read: The effects of speech recognition technology on the reading and spelling performance of children with learning disabilities

In recent literature on persons with learning disabilities (LD), speech recognition has been discussed primarily as an assistive technology to help compensate for writing difficulties. However, prior research by the authors has suggested that in addition to helping persons to compensate for poor writing skills, speech recognition also may enhance reading and spelling; that is, what was designed as assistive technology appears to serve remedial functions as well. The present study was conducted to determine whether elementary and secondary students with LD who used the technology to write self-selected compositions and class assignments would demonstrate improvements in reading and spelling. Thirty-nine students with LD (ages 9 to 18) participated. Nineteen participants used speech recognition 50 minutes a week for sixteen weeks, and twenty students in a control group received general computer instruction. Results indicated that the speech recognition group showed significantly more improvement than the control group in word recognition (p<.0001), spelling (p<.002) and reading comprehension (p<.01). Pre- and posttests on five reading-related cognitive processing measures (phonological, orthographic, semantic processing, metacognitive reading strategies, and working memory) indicated that for the experimental group, only phonological processing improved significantly over the treatment period when compared to controls (p<.04). Further ANCOVA suggested that growth in phonological processing was associated with significant differences among conditions for all three academic measures: word recognition, spelling, and reading comprehension.

The adult outcomes of children with learning disabilities

The results of four follow-up studies of learning-disabled children are reviewed. A comparison of results among the studies and of analyses of individual variation within the studies suggest some factors associated with long-term outcomes. It is argued that in many cases learning disabilities are not a lifelong handicapping condition, especially if adequate treatment is provided during childhood.     

Comprehension of humor in children with nonverbal learning disabilities,reading disabilities,and without learning disabilities

The normal development of humor in children has been well documented with a predictable course that is tied to social, cognitive, and linguistic development in children. This study explored humor comprehension in children with nonverbal learning disabilities (NVLD). Children with NVLD were compared with children with reading disabilities and a comparison group of children with no learning disabilities to assess their comprehension of humor. The humor test was composed of a joke and cartoon section. No group differences in humor comprehension were found when the NVLD group was defined as having visual–spatial and visual reasoning deficits. However, when the NVLD group was divided into children with and without social perceptual difficulties as defined by a direct measure of social comprehension, significant group differences were found in the levels of humor comprehension. These results support the association of humor comprehension with social perception and lend tentative support to the hypothesis that children with NVLD may not be a homogenous group. Future study directions include further exploration into the nature of the association between humor comprehension and social perception as well as closer examination of the heterogeneity of NVLD.     

Metaphoric competence in children with learning disabilities

Metaphoric competence was examined in two groups of children with learning disabilities and one group of nondisabled peers ranging in age from 9-0 to 11-0 years. There were five girls and seven boys in each group. One group of students with learning disabilities had a history of spoken language impairment and the other group did not. Subjects were administered three verbal metaphor tasks (comprehension, preference, and completion) and a visual metaphor task, the Metaphor Triads Task (MTT). The three verbal metaphor tasks were administered in three contexts: (a) sentence, (b) story, and (c) story plus visual (pictorial) support. The group with a history of language impairment consistently performed more poorly on the metaphor tasks than the group without a history of language impairment, who, in turn, performed more poorly than the nondisabled children on all but the MTT. Context variations had no effect on children's performance. Theoretical and clinical implications will be discussed.     

Comparison of visual-spatial performance strategy training in children with Turner syndrome and learning disabilities.

This study examined the effects of a verbal mediation strategy on three groups of subjects who had visual-spatial deficits. Thirteen females with Turner syndrome, 13 females with nonverbal learning disabilities, and 14 males with nonverbal learning disabilities, who ranged in age from 7 to 14 years, were taught via a cognitive behavioral modification approach to verbally mediate a spatial matching task. Pretest and posttest performance differences on parallel forms of a visual-spatial orientation task were examined. All three groups showed significant improvement in visual-spatial task performance after the training. There were no significant differences in the degree of improvement among the three groups. The results suggest that children with Turner syndrome may benefit from problem-solving strategy training in a manner similar to children with nonverbal learning disabilities.     

Associations between academic and motor performance in a heterogeneous sample of children with learning disabilities

A heterogeneous sample of 137 school-aged children with learning disabilities (IQ > 80) attending special needs schools was examined on the Movement Assessment Battery for Children (MABC). The results show that compared to the available norm scores, 52.6% of the children tested performed below the 15th percentile on manual dexterity, 40.9% on ball skills, and 33.7% on balance skills. Furthermore, after controlling for IQ, significant small to moderate partial correlations were found between spelling and mathematics and the MABC total score, as well as small to moderate correlations between mathematics and balance, between reading and ball skills, and between spelling and manual dexterity. The present findings are compared with previously reported results obtained in more homogenous groups, and based on the resultant relationships between academic performance and motor development, recommendations for future motor intervention studies are made.     

Attention performance in young adults with learning disabilities

Attention acts as the mind's “gatekeeper” by regulating and prioritizing the stimuli processed by the central nervous system. It is essential for cognitive performance, memory, and behavior, and we know that even slight deficiencies in attention compromise learning. Basic neuroscience research further indicates that attention consists of (fairly) independent subcomponents, which rely on distinct neural structures, and serve different functions in everyday behavior. Disturbances of brain function, such as those suggested to be related to learning disabilities, may lead to different patterns of attention performance (i.e., some attention systems may work sufficiently well, while others are substantially impaired). The present experiment describes a pilot study that aimed to characterize the extent and range of individual variations in attention performance in persons classified as learning disabled. Specifically, we tested the hypothesis that attention is not uniformly impaired in these individuals. Rather, we expected some subcomponents to be more severely impaired than others, and substantial heterogeneity in the individual “deficit patterns.”The Test of Everyday Attention (TEA) was used to assess visual selective attention, attentional switching, sustained attention, and auditory–verbal working memory in students with nondyslexic learning disability (LD group) and matched controls. The group comparison revealed a significantly weaker performance in the LD group. Analysis of subtest-specific scaled scores further indicated great individual differences in the performance pattern. Thus, in each student with LD, we found normal performance in at least two subtests, while other subcomponents where severely impaired. The study supports the idea of differential attention deficits in the learning disabled, and suggests individual patterns of “strengths and weaknesses.” Taking the relationship of attention and learning into account, this finding is important with respect to the design of individual learning programs and the teaching techniques chosen for the acquisition of skills and knowledge.     

Conversational engagement of children with learning disabilities

This study was designed to characterize the conversational engagement techniques employed by children with and without learning disabilities while in a dyadic interaction. Engagement was defined and measured in terms of the degree to which utterances provided information and evidenced responsiveness to one's conversational partner. Sixty (30 with learning disabilities and 30 nondisabled) 9- to 13-year-old subjects participated. Analyses indicated that the subjects with learning disabilities (LD) could and did employ engagement-related techniques similar in levels of sophistication to those of their nondisabled peers, although they did so less consistently and frequently. Further, the relationship between affective measures and the engagement-related techniques used by the subjects with LD differed markedly from those of the nondisabled subjects. The results are interpreted from a motivational standpoint and suggest that future research should focus on the knowledge and application of engagement-related techniques of the children with LD, across settings and conversational partners.     

The prevalence of depressive symptoms in children with learning disabilities.

Learning difficulties have been considered to be a symptom of childhood depression by some authors, whereas others have examined depression as a cause of cognitive difficulties, including learning disabilities (LD). This study examined the prevalence of depressive symptoms in a sample of public school elementary children aged 8 through 11, 37 boys and 16 girls, identified as LD by state standards. Of the sample of 53 children, 35.85% scored in the depressed range on the Children's Depression Inventory. Comparison of the children's self-reports and parents' reports of depressive symptoms in their children was not significant. Implications of the results are discussed relative to the role of school personnel and the assessment process in recognizing depressive symptoms in students with LD.     

The inhibition of exogenous distracting information in children with learning disabilities

Several studies have shown that children with learning disabilities (LD) have difficulty in inhibiting irrelevant information, which generates endogenous interference from working memory. Other inhibition capacities have not yet been investigated, however. This article reports on an experiment examining the capacities of children with LD to inhibit exogenous interference, such as automatic, prepotent responses and distractor interference. Fifteen 11-year-old children with LD and 15 matched controls completed four tasks of inhibition, using the Stroop and Eriksen's flanker paradigms. To test the hypothesis that inhibition can be differentiated in terms of the type of material it acts on, each paradigm was used with numerical and nonnumerical stimuli. Our results showed that children with LD did not exhibit significantly larger interference effects than controls. Moreover, the pattern of results did not differ according to the type of material used. These findings indicate that children with LD do not show impairment in the inhibition of exogenous information--a finding that contradicts the material-specific inhibition hypothesis.
