Data analysis of 134 twin pairs from the Colorado Reading Project found that approximately 40 percent of the deficit observed in disabled readers is because of genetic factors, 35 percent because of environmental influences shared by twin pairs, and 25 percent because of environmental factors unique to the individual and/or error variance.…

The prereading and reading performance of 370 predominantly Hispanic, bilingual school children was followed for 6 years. A 5-test Screening Index misclassified many failing readers but accurately identified children who eventually read well. Predictor tests administered at beginning of first grade showed significant correlations with reading at…

This study examined the development of phonological and reading skills in 171 students from the beginning of first grade (Time 1) to the end of second grade (Time 4). The study found that reader group membership (nondisabled, reading disabled, or poor reading) at Time 4 could be very accurately predicted from students' Time 1 scores. (Author/DB)

This study examined possible early predictors of reading problems in at-risk children (ages 53 to 77 months). Results indicated that early measures of language awareness are good predictors of later reading performance but that different measures are good predictors for different children. (Author/DB)

Language abilities from age 2-5 were studied in 4 children with early language delays. Deficits became milder and more selective, with normal or nearly normal speech/language proficiency by age 60 months. But at 3-year follow up, 3 of the 4 cases were severely reading disabled. (Author/JDD)

The study found that primary grade children with reading impairments (n=24) or learning disabilities (n=8) demonstrated a marked deficit in ability to discriminate patterned pairs of tones on the Seashore Rhythm Test compared to controls (n=26). Results suggest use of the test to detect young children with potential reading problems. (Author/DB)

The accuracy of SEARCH for identifying children at risk for developing learning disabilities was evaluated with 1,107 kindergarten children. Children identified as at risk were of average intelligence. SEARCH scores were significantly correlated with sequential and simultaneous information processing skills. SEARCH predicted adequacy of…
