Language Stimuli Screening in Children

This study will determine baseline language skills in children 4 to 8 years old. The data will be used to design studies using functional magnetic resonance imaging (fMRI) to identify what areas of the brain in children are involved in understanding language. This information is important for children who require brain surgery to control seizures. Healthy normal volunteers between the ages of 4 and 8 years who have an IQ of 70 or more; who have no history of neurologic, psychiatric or language disorder; who are performing at or above grade level, and who are native English speakers may be eligible for this study. Participants will be asked to do the following: * name pictures or read words that appear on a computer screen * listen to stories and answer questions about them * match pictures to a spoken word The children's responses will be recorded.
