This study explored the contribution of perceived loudness cues to mismatch negativity produced in response to a 125 ms duration deviant tone among a regular sequence of 50 ms standard tones. Each individual was required to adjust the intensity of a 125 ms tone until it matched the perceived loudness of a 50 ms tone. The mismatch negativity produced to the duration deviant presented at the same intensity as the standard was contrasted with that produced to the same deviant at each individual's perceived loudness equivalence. Despite a detectable difference in perceived loudness (∼1.3 dB), adjusting the intensity of the deviant tone did not significantly reduce mismatch negativity amplitude to the duration deviant. Results are discussed with reference to temporal window of integration.
