This research is designed to examine the accuracy with which a change in the moment of detection of a duration deviance is
reflected in the Mismatch Negativity (MMN) peak latency. MMNs were recorded using the oddball paradigm on healthy adults. Different
standard stimulus durations are used and deviants are 50% shorter or longer. Beside the temporal resolution of the MMN latency as a
function of the theoretical moment of deviance direction, standard duration as well as deviance directions effects on MMN amplitude
and latency are also examined.
