The author contends that, while visual defects should not be confused with defects in visual perception, the identification and treatment of visual problems is an important element in the diagnosis and remediation of learning disabilities. (Author)

Comparison of community children referred for learning disability evaluation (CR, n=17) with children not-referred in community general education (CGE, n=161), community special education (CSE, n=30), or from outpatient hospital referrals (HR). CR group performance was equivalent to that of CSE and HR groups. Results suggest conceptualizing…

This study found that 331 Toronto (Ontario, Canada) adolescent and adult subjects with learning disabilities could be grouped into three subtypes: (1) arithmetic disability, (2) reading disability, and (3) reading and arithmetic disabilities. Each group differed significantly from the others on tests of reading, spelling, memory, and other…

This study compared students diagnosed with learning disabilities (n=2,053) and students without learning disabilities (n=2,200) on the Learning Disability Index (LDI). Subsamples of specific reading and math disabilities permitted further assessment. Analysis indicated the LDI resulted in a correct diagnostic decision only 55 to 64 percent of the…

Evaluation of the relationship between hyperactivity and learning difficulties in 1,593 Australian elementary students indicated twice as many males as females with learning difficulties; 11% of the sample were hyperactive; 41% of the subjects with learning difficulties were also hyperactive; and 3.2% of all subjects had both hyperactivity and…

The problem of choosing educational and psychological tests to identify students with learning disabilities is discussed within a cost-efficiency framework. An efficiency index for estimating the classification accuracy of tests is presented and the use of expert judgment and the cost-effectiveness ratio is demonstrated with a numerical example.…

Self-reported reading ability of parents of 174 reading-disabled children and of 182 controls was used to estimate the probability that a child will become reading disabled. Using Bayesian inverse probability analysis, it was found that the risk for reading disability is increased substantially if either parent has had difficulty in learning to…

The article posits that emotionally disturbed (ED) children routinely are diagnosed as learning disabled (LD), a situation deriving from diagnostic problems and inadequacies of definitions. Among suggestions made for special educators are knowing ED and LD definitions, and becoming assertive as evaluation team members. (MC)

Data from reports of the federally funded Child Service Demonstration Centers (CSDCs) are said to show that only three CSDCs adhered to all criteria in the federal definition of learning disabilities. The author suggests that LD should be adopted as a generic term for all mild handicaps. (CL)

The investigation explored the use of R. Cattell's ability traits (fluid and crystallized intelligence, visualization, and fluency) as a method of comparing 45 normal, learning disabled (LD), or educable mentally retarded (EMR) children (ages 7 to 9). (Author/PHR)

This article addresses the proposal of Shaw and others (1995) to replace the current federal definition of learning disabilities with an operationalized version proposed by the National Joint Committee on Learning Disabilities in the reauthorization of the Individuals with Disabilities Education Act. Comparison of Shaw's recommendations with…

Concurrent validity of the Kaufman Brief Intelligence Test (K-BIT) with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was evaluated. Both measures were administered to 65 children (ages 6-7). Results suggest caution against using the K-BIT exclusively for placement and diagnostic purposes with young children with reading…

E. Burns' (1984) attempt to explain the below average mean IQ scores reported for samples of learning dsabled (LD) students through the use of the bivariate normal probability distribution was examined. Alternative explanations which focus on issues related to the referral, identification, and placement of children are presented.(Author)

This study investigated the incidence of learning disabilities in 105 children (ages 6-18) with neurofibromatosis Type 1 (NF-1). Results found that nearly 70% of the subjects were academically deficient and 42% met the criteria for learning disabilities. A low incidence of visuospatial-constructional deficits was also found. (Author/CR)

Students (n=210) in learning disabilities research centers were administered the Wechsler Intelligence Scale for Children-Revised and the Woodcock-Johnson Psychoeducational Battery-Revised. A model considering the reliability of each measure identified learning disabilities three times more often than a regression analysis model. The regression…
