Objective: We hypothesized that mental arithmetic is a complex of sequential information processing. In order to test the hypothesis, event-related potentials (ERPs) were measured during 3 mental tasks. Methods: Fifteen normal human subjects performed the following tasks; (1) subjects added up every...
