Mathematics and learning disabilities

Between 5% and 8% of school-age children have some form of memory or cognitive deficit that interferes with their ability to learn concepts or procedures in one or more mathematical domains. A review of the arithmetical competencies of these children is provided, along with discussion of underlying memory and cognitive deficits and potential neural correlates. The deficits are discussed in terms of three subtypes of mathematics learning disability and in terms of a more general framework for linking research in mathematical cognition to research in learning disabilities.     

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.     

The sociopsychometrics of learning disabilities

The Boston University (BU) case illustrates how the psychometrics of ability differences interact with the concept of learning disability and with the sociopolitics of schooling and society. It also illustrates that learning disabilities advocacy will not be on a sound footing as long as the field refuses to rid itself of its IQ fetishism, refuses to jettison its fixation on aptitude-achievement discrepancy, and fails to free clinical practice from the pseudoscientific neurology that plagued the field in the 1970s. A more inclusive definition of learning disability--one that abandons discrepancy notions--and a more self-critical attitude toward its own claims would advance the field of learning disabilities and help to rid it of distractions such as the BU case.     

Success despite specific learning disabilities

Abstract

Proactive coping is known to be a key resource for life success by adults who have specific learning disabilities. This paper describes two programs that were trialled as part of doctoral research. These were a coping program and a teacher feedback intervention designed to increase proactive coping for adolescent students with specific learning disabilities. The coping program focused on use of proactive coping strategies, optimistic thinking and assertiveness, and was designed according to best practice for access by students who have specific learning disabilities. The teacher feedback intervention involved teacher feedback to individual students that focused on expectation of use of effort, and strategy in preference to negative rumination on poor ability.     

Familial patterns of learning disabilities

Extended families of 12 young adults (9 LD, 3 non-LD) were given a battery of tests and questionnaires, and 131 persons, ranging in age from 6 to 85, were classified as LD or non-LD on the basis of subtest scores 1 SD below the mean or less on subtests of the PIAT and WRAT achievement tests. Pedigree analysis indicated that LD was strongly familial, with the most probable mode involving a major gene effect, but the type of disability (reading/ math) was not directly inherited. Autoimmune disorders were significantly correlated (P<.005) with LD, especially in families in which LD remained a major handicap into adulthood, a trait that also varied between families. In two of the LD families, adults showed little evidence of the reading/spelling deficits they had shown when tested as children, while adults in other families failed to make gains in reading and spelling.     

Cognitive abilities and learning disabilities

Summary The greater discrepancy between spatial vs sequential/conceptual WISC subtest results in learning-disabled children is instrumental to the idea that these children might profit relatively more from an imagery based strategy in organizing and recalling noun pairs and triplets than from a verbal strategy. The results from the present studies with concrete nouns show that this is not the case. Another result is that learning-disabled children’s recall performance is also lower when strategy instructed (except in the first experiment) than normal children’s performance. Suggestions as to which strategy aspects could be responsible are given. This paper is based upon a presentation at the 30th Annual Conference of The Orton Society in Indianapolis, November 1979.     

Imagery deficits in nonverbal learning disabilities

This study reports the observations gathered from 11 children referred to consulting services because of learning difficulties at school and diagnosed with nonverbal learning disabilities (NVLD). These children had an average verbal IQ, but a WISC-R performance IQ lower than the verbal IQ by at least 15 points and experienced difficulties especially in mathematics and drawing. The children completed a battery of four tasks requiring visuospatial working memory and visual imagery: a memory task composed of pictures and their positions (Pictures task), a task that required them to memorize the positions filled in a matrix (Passive Matrix task), a task that required them to imagine a pathway along a matrix (Active Matrix task) and a task that required them to learn groups made up of three words, using a visual interactive imagery strategy (TV task). In comparison to a control group of 49 children, children with NVLD scored lower in all the tasks, showing deficits in the use of visuospatial working memory and visual imagery. By contrasting subgroups of children of different ages in the control group, it was possible to show that some tasks did not show a clear developmental trend. Thus the deficits shown by the children with NVLD cannot simply be attributed to a developmental delay of these children, but seem to reflect a more severe disability.     

The social construction of learning disabilities

Underpinning the technical gaze that dominates learning disabilities theory and practice is the assumption that learning disabilities are a pathology that resides in the heads of individual students, with the corollary that remedial efforts also focus on what goes on in the heads of students classified as learning disabled. This article begins with a critique of the ideology of individualism that situates individual success and failure in the heads of individuals as a means of introducing an alternative perspective--social constructivism--that locates learning and learning problems in the context of human relations and activity. Extended examples are used to illustrate how the performative aspects of learning disabilities emerge in the context of human relationships. The primary argument developed here is that one cannot be learning disabled on one's own. It takes a complex system of interactions performed in just the right way, at the right time, on the stage we call school to make a learning disability. The article concludes with a brief consideration of the instructional implications of a social constructivist stance.     

Nonverbal learning disabilities and remedial interventions

Adolescents with nonverbal learning disabilities who enroll in private, special secondary schools consistently present a pattern of behaviors which prevents achievement of their potentials in academic areas and impedes their abilities to interact effectively with others. With weaknesses in the fine graphomotor skills for writing and poor organization at all levels, they produce limited written output and often fail to complete academic assignments. Their response to pressure to produce is to become less productive. These students perceive social situations inaccurately; they are not successful in their interactions, especially with peers. They have learned to resolve difficult situations by employing their relatively strong verbal skills to enlist parents and other adults in intervening for them. They have not developed the skills to intervene for themselves. Effective remedial interventions include training the students in skills for planning and organizing, for studying, for written expression, and in social cognition and interpersonal communication. Students gain positive feelings of personal effectiveness through a process—at first verbally mediated, ultimately verbally self-directed—in which they are encouraged to plan, risk, and act on their own behalfs to resolve matters of personal concern.
