Mismatch negativity measures of gap detection

Renee Desjardins, Laurel Trainor


The feasibility of using event related potentials to measure temporal resolution in adults was examined. Gap detection threshold was measured using a mismatch negativity measure with a right frontal focus. The measured threshold of around 4 ms is in agreement with the behavioral literature. Although a P3a following the MMN, perhaps indicating inadvertent capture of attention, a clear MMN could be measured, suggesting that MMN may be a good method for measuring thresholds in nonlinguistic infants.
