Mismatch negativity (MMN) is a pre-attentive event-related potential measure of echoic memory. However, recent studies suggest attention-related modulation of MMN. This study investigates duration-elicited MMN in healthy subjects (n = 12) who were performing a visual discrimination task and, subsequently, an auditory discrimination task in a series of increasing task difficulty. MMN amplitude was found to be maximal at centro-frontal electrode sites without hemispheric differences. Comparison of both attend conditions (visual vs. auditory), revealed larger MMN amplitudes at Fz in the visual task without differences across task difficulty. However, significantly smaller MMN in the most demanding auditory condition supports the notion of limited processing capacity whose resources are modulated by attention in response to task requirements.
