我们提出的上下文维护和检索(CMR)模型的记忆搜索,一个广义版本的时间上下文模型(TCM)的,它提出了记忆搜索是由一个内部维护的上下文表示组成的刺激相关和源相关的功能。在CMR模型中,组织效应(在回忆序列中相关项目聚集的趋势)是由于活跃的上下文元素和所研究材料的特征之间的关联而产生的。语义聚类是由于长期存在的上下文到项目的关联,而时间聚类和源聚类都是由于在研究过程中形成的关联。对三种组织形式的行为调查提供了约束CMR模型的数据,揭示了组织因素之间的相互作用。最后,我们讨论了CMR对我们理解广泛的情景记忆现象的影响,并提出了该理论可以指导我们探索记忆搜索的神经相关因素的方法。
We present the Context Maintenance and Retrieval (CMR) model of memory search, a generalized version of the temporal context model (TCM) of, which proposes that memory search is driven by an internally maintained context representation composed of stimulus-related and source-related features. In the CMR model, organizational effects (the tendency for related items to cluster during the recall sequence) arise as a consequence of associations between active context elements and features of the studied material. Semantic clustering is due to longstanding context-to-item associations, whereas temporal clustering and source clustering are both due to associations formed during the study episode. A behavioral investigation of the three forms of organization provides data to constrain the CMR model, revealing interactions between the organizational factors. Finally, we discuss the implications of CMR for our understanding of a broad class of episodic memory phenomena, and suggest ways in which this theory may guide our exploration of the neural correlates of memory search.
