Research Goals. The research plan is to identify sources of reading-related difficulties in sentence comprehension that are most subject to individual differences, and to study their cognitive and neural underpinnings. The investigators are using an eyetracker to study comprehension on-line in adolescents with greater and lesser comprehension ability. fMRI is used to expose brain activity during reading. Finally computational modeling is being used to predict behavioral and neural patterns.

Current Status. The project was approved for funding on March 1, 2002 for three years. It was renewed for five years beginning 5/15/06.  Total costs for the second year are $435,743.
