Sonar operators listen to and interpret complex auditory signals for thousands of hours over a period of years. They develop an expertise in tone discrimination that could be expected to influence how they process auditory information, which would change their task-related brain electrical activity. The evidence thus far suggests that the brain electrical activity of experts is different from that of novices. Experts may be of different ages and several studies have shown that ERPs change with aging. Therefore, the affect of sonar experience and age on auditory ERPs was investigated. The results reported, concerning age and ERPs, support and extend the results of previous studies. Although other experience-related ERP studies found that various components and distributions were related to task experience their results were not supported.
