Abstract
Timbre is a key and complex attribute of sound that might be pre-attentively coded in sensory memory, and the mismatch negativity (MMN) component of event-related potential (ERP) might be adopted to detect this process. The present study investigated the timbre MMN in an oddball paradigm, with piano tone as standard, and sine wave or trumpet tone as deviant separately. Both deviants evoked a MMN component in a streaming of piano tones. Statistical analysis indicated that MMN for pure tone was significantly larger in magnitude than that for trumpet tone. The results evinced that the involuntary processing of timbre variations was relate to not to the spectral complexity but to the discrepancy between the standard and deviant tone.
