FORGETTING AND REMEMBERING DURING COMPETITIVE MEMORY RETRIEVAL

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。情节提取通常涉及在来自相互竞争的记忆的干扰中选择目标。为了探索面对竞争的提取过程中的神经生物学机制，以及有助于抑制选择性-对抗竞争者的机制，我们使用功能磁共振成像来研究提取诱导的遗忘(Anderson，Bjork，&Bjork，1994)。参与者(n=13)最初研究了线索？联想单词对，学习了每个线索的多个联想。随后，参与者对一些线索的部分伙伴进行了提取练习。最后，对所有项目进行线索回忆测试。行为数据复制了提取诱导的遗忘效应：没有练习过的线索(竞争者)的未经练习的同伴比没有练习的线索(基线项目)的未经练习的同伴更不可能被回忆起？？抑制竞争记忆的行为证据。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Episodic retrieval often involves selection of a target amidst interference from competing memories. To explore the neurobiological mechanisms recruited during retrieval in the face of competition and the mechanisms that contribute to the suppression of selected-against competitors, we used fMRI to study retrieval-induced forgetting (Anderson, Bjork, & Bjork, 1994). Participants (n=13) initially studied cue¿associate word pairs, learning multiple associates for each cue. Subsequently, participants performed retrieval practice for some of the associates of some of the cues. Finally, a cued recall test was administered for all items. Behavioral data replicated the retrieval-induced forgetting effect: unpracticed associates of a practiced cue (competitors) were less likely to be recalled than unpracticed associates of an unpracticed cue (baseline items)¿behavioral evidence for suppression of competing memories.
