Little is known about the underlying causes and developmental patterns of stability and change in early reading abilities. In a longitudinal study of twins (n=4,291 pairs), individual differences in reading achievement assessed by teachers using U.K. National Curriculum (NC) criteria showed substantial heritabilities at ages 7, 9, and 10 years…

A sample of 80 first- and second-grade children selected to represent four levels of reading competence were tested in their recognition of semantic, syntactic, and lexical change in sentences previously decoded during prose reading. (JMB)

Investigates recall of toy preferences in the parents of 56 four-year-old children classified either as early readers or as nonreaders. Results indicated that early readers cannot be differentiated by IQ or family demographic information alone and that consistent toy preferences precede the acquisition of early reading skills.

At 30 months, children who were later considered dyslexic were deficient in length, sytactic complexity, and pronunciation of spoken language. At three years, children were deficit in receptive vocabulary and object-naming, and at five years, in phonemic awareness and letter-sound knowledge. These deficits were not found in normal reading children…

Infants' visual recognition memory (VRM) at seven months was associated with their general intelligence, language proficiency, reading and quantitative skills, and perceptual organization at six years. Infants' VRM, object permanence, and cross-modal transfer of perceptions at one year were related to their IQ and several outcomes at six years.…
