The Contingent Negative Variation (CNV) and the Lateralized Readiness Potential (LRP)
can be used as indicators for premotor and motor preparation during the foreperiod, respectively.
This rationale can be applied in the study of mechanisms for error processing, that are active in response to both self generated
errors and errors committed by others. The Anterior Cingulates Cortex (ACC) and the motor cortex are involved in the
observation of errors. The error related negativity (ERN) is used as a measure of ACC activity, and the lateralized readiness
potential (LRP) is used as a measure of relative activation of the participant�s motor cortices.
