Abstract: Abstract Does intentional forgetting require cognitive effort? In directed forgetting research, the forgetting of F items is the result of passive decay, that is, the selective rehearsal of R items make F items unable to obtain effective rehearsal and passively decay,this process does not require efforts; It may also be the active inhibition of memory processing induced by F-cue, which has been supported by a large number of brain cognitive studies, mainly reflected in the strong activation of prefrontal lobe,reflecting the need for cognitive efforts; There is also a possibility that both active suppression and passive decay exist, but the time and space of their occurrence are different. Future research needs to further explore the cognitive mechanism of directed forgetting, constantly avoid the defects in the design of directed forgetting, consider the influence of non-cognitive factors, integrate the theoretical controversies and pay attention to the forgetting characteristics of different groups.
