本研究支持言语短时记忆的激活模型，包括语义的保留过程的贡献。事件相关脑电位被用来探测激活的水平的语义表征的一系列单词在延迟间隔后，他们的介绍。在两个任务中比较激活水平：（1）短时记忆任务，涉及延迟间隔后回忆阶段的语义判断;（2）非记忆控制任务。在短时记忆任务中，延迟间隔期间的语义激活水平较高，表明增强的语义表征激活参与了言语信息的短时存储。这一结果意味着，激活的长期记忆提供了一个代表性的基础，语义口头短期记忆，因此支持的理论，假设短期和长期存储是不分开的。
The present study supports activation models of verbal short-term memory that include a semantic contribution to the retention process. Event-related brain potentials were used to probe the level of activation of semantic representations of a series of words in a delay interval following their presentation. The levels of activation were compared in two tasks: (1) a short-term memory task that involved a semantic judgment in the recall phase following the delay interval, and (2) a nonmemory control task. The level of semantic activation during the delay interval was higher in the short-term memory task, indicating that enhanced activation of semantic representations is involved in the short-term storage of verbal information. This result implies that activated long-term memory provides a representational basis for semantic verbal short-term memory, and hence supports theories that postulate that short- and long-term stores are not separate.
