Duration and pitch deviants
WebDec 30, 2005 · Two different deviants, a change in tone duration to 190 ms and a change in tone pitch to 300 Hz (with partials of 600 and 900 Hz), were presented in the same stimulus sequence with probabilities of 5% each. The deviants were otherwise identical to standards. Sound intensity was 56 dB SPL at the subject‘s head. WebDec 3, 2024 · As observed in previous studies, pitch-deviant tones impaired the discrimination of tone duration and triggered a sequence of event-related potentials (ERPs) reflecting a cycle of deviance detection, involuntary attentional distraction and reorientation (MMN, P3a, RON).
