Tartalmi leírás:
The N1 and P2 event-related potentials (ERPs) are attenuated when the eliciting sounds coincide with our own actions. Although this ERP attenuation could be caused by central processes, it may also reflect a peripheral mechanism: the co-activation of the stapedius muscle with the task-relevant effector, which reduces signal transmission efficiency in the middle ear, reducing the effective intensity of concurrently presented tones, which, in turn, elicit lower-amplitude auditory ERPs. Because stapedius muscle contraction attenuates frequencies below 2 kHz, no attenuation should occur at frequencies above 2 kHz. A self-induced tone paradigm was administered with 0.5, 2.0, and 8.0 kHz pure tones. Self-induced tones elicited attenuated N1 and P2 ERPs, but the magnitude of attenuation was not affected by tone-frequency. This result does not support the hypothesis that ERP attenuation to self-induced tones are caused by stapedius muscle contractions.
