In order to compare processing across operations, we recorded event‐related potentials ( ERP s) elicited by both problems and solutions in addition, subtraction, multiplication, and division conditions in a delayed answer verification task. Amplitudes of an early negativity, P 300, and late positive component ( LPC ) elicited by solutions were sensitive to the correctness of the presented answers within operations and differed across operations only for incorrect solutions. The early negativity resembled an N 270 rather than an N 400. The amplitude of an N 300 elicited by problem presentations also differed across operations. Our results indicate that ERP s are sensitive to differences in processing across arithmetic operations in an answer verification task both during presentation of the problems, when production/retrieval processes occur, and during comparison of incorrect presented solutions with expected solutions.
