The sensitivity of event-related potentials (ERPs) to the processes of recollection and familiarity has been explored extensively, and ERPs have been used subsequently to infer the contributions these processes make to memory judgments under a range of different circumstances. It has also been shown that event-related fields (ERFs, the magnetic counterparts of ERPs) are sensitive to memory retrieval processes. The links between ERFs, recollection and familiarity are, however, established only weakly. In this experiment, the sensitivity of ERFs to these processes was investigated in a paradigm used previously with ERPs. An early frontally distributed modulation varied with memory confidence in a way that aligns it with the process of familiarity, while a later parietally distributed modulation tracked subjective claims of recollection in a way that aligns it with this process. These data points strengthen the argument for employing ERFs to assess the contributions these processes can make to memory judgments, as well as for investigating the nature of the processes themselves.
事件相关电位（ERP）对回忆和熟悉过程的敏感性已得到广泛研究，随后ERP被用于推断这些过程在一系列不同情况下对记忆判断的贡献。研究还表明，事件相关场（ERF，ERP的磁对应物）对记忆检索过程敏感。然而，ERF与回忆和熟悉之间的联系仅得到微弱的确立。在本实验中，采用先前用于ERP的范式研究了ERF对这些过程的敏感性。一种早期的额叶分布调制随记忆信心而变化，其方式与熟悉过程一致，而一种后期的顶叶分布调制以与回忆过程一致的方式跟踪主观回忆声明。这些数据点强化了采用ERF来评估这些过程对记忆判断的贡献以及研究这些过程本身性质的论据。
