Project II: Reading and Language Processes

Principal Investigator: R.K. Olson

Co-Investigators: D. Compton & J.M. Keenan

Goals of Project II: The objectives of this project are to measure component processes and knowledge in reading and related language skills, and to assess genetic and environmental etiologies of group deficits in these processes. In addition, the etiologies of covariation among these measures, and between these measures and the measures of cognitive abilities and academic achievement administered in Project I, as well as with measures of ADHD administered in Project III. Behavior genetic analyses are also used to validate subtypes and/or dimensions of individual differences among children with reading deficits. In collaboration with investigators from research projects I and IV, QTL analyses are used to assess genetic linkage for deficits in different reading and language skills.
