Event related potentials in children with learning disabilities. Visual event related potentials in specific Kanji writing disabilities

Event related potentials in two patients with learning disability in specific 'Kanji' writing were investigated using newly made tasks of familiar simple Kanji, unfamiliar complex Kanji and meaningless complex figures. These tasks are made with full consideration of their clinical neuropsycological symptoms. These patients showed different patterns of abnormalities in these tasks compared with control subjects. These findings suggested the different underlying mechanism of the same clinical symptoms and are helpful to consider strategy of their education and training.
