A study that followed 1,008 children from prekindergarten through grade seven or eight for 13 years found that defining reading comprehension disability in terms of a discrepancy between group-administered tests of listening and reading comprehension provided a fairly accurate estimate of the stability, gender ratio, and prevalence of the…

Two cohorts of preschool children (n=238) were followed to determine whether tests of phonological awareness, orthographic processing, and serial-naming speed, added to a preschool battery, would improve prediction of reading. The major predictors of first-grade reading and spelling were preschool letter-naming and sentence memory for both…

Students (ages 6-10, n=144), grouped by age and reading ability, were administered tasks with a demonstrated relationship to reading. The concept of dyslexia was supported only for the older group, for whom dyslexia appeared to be either a phonological deficit or a developmental lag. (Author/DB)

Three-hundred kindergarten children were screened with a test battery in order to identify children at high-risk of experiencing learning disabilities. (Author/DB)

WPPS (Weschsler Preschool Primary Scale of Intelligence) and screening test scores of 72 children at risk for learning disability at age five were examined three years later. At follow-up there were 32 poor and 40 good readers. Both groups had average intelligence at age five and had received similar special help. (Author/CL)

In a follow-up of 208 boys, the 16 who scored low on a prekindergarten screening battery, but were satisfactory readers four years later, were compared with 13 others low on both prekindergarten and reading measures. Fourteen of the good readers, but only one poor reader, were classified by criteria consisting mainly of biographical variables.…

Scores on the Holbrook Screening Battery, administered at age four, correctly predicted 89 percent of good readers and 75 percent of poor readers in a sample of 116 eighth graders. Characteristics differentiating good and poor readers included birth history, family history of learning disability, speech delay, and socioeconomic status. (Author/DB)

Among four-year groups of children in a school system (266 girls, 284 boys), 4 percent had a reading disability and 2.7 percent were "slow learners." Reading disabled boys tended to be later born in their families. Lower reading scores were associated with hot birth month temperatures for all socioeconomic groups. (Author/CL)

Twenty-two seventh and eighth grade students poor in mathematical computation but with average reading comprehension (low math group) were compared with two matched groups: low reading group and no difference group. It was concluded that children with a disability in mathematical computation may be at risk for impulsive and possibly antisocial…
