This study investigated whether a latent class of children with math difficulties (MD) or math learning disabilities (MLD) emerged within a heterogeneous sample of learners. A latent class analysis was computed on children (N = 447) in Grade 3 who were administered a battery of math, reading, and cognitive measures. The analysis yielded four…

The paper describes learning disability or reading disability in terms of deficiencies in processing information. An integrated view of intelligence as cognitive processing is offered followed by a demonstration of how tests of information processing have successfully revealed strengths and weakness of cognitive processes relating to reading.…

Chronometric methods of cognitive assessment of learning disabled students which measure speed of response to elementary cognitive tasks requiring minimal prior knowledge are discussed. Chronometric techniques known to correlate with IQ and other indexes of mental efficiency and scholastic proficiency are described. (Author/DB)

This document notes that arithmetic disabilities can occur with an otherwise normal intelligence level. Two models of explanation are given. The first emphasizes the conditions under which children learn mathematics, the second views the identification of a number of factors in the "structure of intelligence" that appear to be strongly…

Tasks involving several areas of cognitive functioning were given to 10 psychotic children and 30 normal children. Comparisons of performance were made between the two groups and also within the psychotic group. The dimension for differentiation was the psychotic children's varying degree of language facility. The psychotic children were…

It was hypothesized that there are significant differences in intellectual patterns between black and white populations which can be demonstrated on the Wechsler Adult Intelligence Scale (WAIS). A one-way analysis of variance was performed on the subjects' scores on the WAIS subtests and the Verbal, Peformance and Full Scale IQ using the ethnic…
