Evidence from twin studies points to substantial environmental influences on intelligence, but the specifics of this influence are unclear. This study examined one developmental process that potentially causes intelligence differences: learning to read. In 1,890 twin pairs tested at 7, 9, 10, 12, and 16 years, a cross-lagged…

In an exploration of the comprehension process of the beginning reader, 16 first and second grade students were each asked to listen to two stories--one a narrative account and the other an expository passage-- and then immediately to retell them. Recall protocols were compared by propositional analysis for text-related superordinate and…

Children in grades 1-3 were asked to retell and explain a series of riddles. Ability to recall riddles was not predictive of ability to explain them. Three cognitive factors seemed to determine level of riddle competence. Implications concern the relationship of riddle competence to reading ability and metalinguistic facility. (CHK)

Presented is a report on a cross-sectional and longitudinal study concerned with the course of intellectual development in 210 children (6-12 years old) educationally designated as brain damaged (learning disabled and/or behavior problems) and assigned to special school placement. The report is divided into four sections which focus on…

For the past 100 years we have been acting as if education in school was of words, by words, and for words, but in fact verbal literacy was preceded by visual literacy when humans communicated with body language before they had speech. American educators have been concentrating efforts on the left hemisphere of the brain in which the verbal…
