| Research Abstract |
The purpose of this study is to evaluate the cognitive functions of children with mild developmental disorders at the biological level. In particular, event-related brain potentials (ERPs) were used for revealing the attentional function for unexpected changes in the environment. The results indicate that the ERP components reflecting the attentional capture for unexpected change can be used as an index for evaluating individuals' cognitive functions. Additionally, they show that children with ADHD have difficulty in focusing spatial attention on the to-be-attended zone of visual space, which permits irrelevant stimuli to induce greater distraction.
