It is inevitably that human memory would store some disgusting or unwanted information; the information may have negative effects on people’s social adaptability and psychological states. People usually limit the time they spend on thinking about unwanted experiences, a process that begins during encoding, but continues when later reminded by some cues. This study summarizes the electrophysiological components and rhythmic characteristics during the process of motivated forgetting, aiming to reveal the specific electrophysiological indicators of forgetting. And we find that the process of forgetting mainly embodied some changes such as the increase of N2 amplitude, the enhanced power of alpha band, the reduction of theta power and its synchronicity, and the decline of synchronicity between alpha and beta band. While those changes can further successfully predict the occurrence of motivated forgetting. Therefore, the forgetting can be reflected by specific electrophysiological mechanism. And the following researchers may speculate the corresponding cognitive process through the electrophysiological phenomenon.
