The work investigates oscillatory error correlates using the method of Common spatial pattern (CSP). The fast and slow errors as well as correct responses are scrutinized. Correlates were researched in four frequency bands: 4-7 Hz (theta waves), 8-13 Hz (alpha band), 14-16 Hz (beta waves), 17-25 Hz (beta waves). A hypothesis is put forward concerning the nature of the fast erroneous responses, as well as the reinforcement of the correct ones. Hypothesis finds partial evidence. Correlates were found in theta band and beta band. Statistical evaluation of the significance was performed. The correlates in the alpha band did not demonstrate the statistical significance.
