摘要: 摘要 有目的的遗忘需要耗费认知努力吗?定向遗忘研究中F线索引起的遗忘可能是被动衰减的结果,即选择性复述R(记住)项目使得F(忘记)项目得不到有效复述而被动衰减,这种加工不需要努力参与;也可能是F线索诱发的对记忆加工的主动抑制,而且这一抑制机制得到了大量脑认知研究的支持,主要反映在额叶一些区域的激活,体现对认知努力的需求;还存在一种可能性,即主动抑制机制和被动衰减均存在,但是二者的作用时间和空间不同。未来的研究需要进一步探索定向遗忘的认知机制,不断完善定向遗忘设计中的缺陷,考虑非认知因素的影响,对研究的理论争议进行整合并关注不同人群的定向遗忘特征。

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.
