在相隔数秒的单词之间可以观察到一种邻接效应，即时间上相近发生的刺激变得相互关联。对邻接效应的传统解释是，项目表示在短期记忆缓冲区（可容纳少量整数项目的有限容量存储）中处于活动状态时会相互关联。参与者学习并自由回忆了 48 个单词列表。会议结束时，参与者对所有列表中的所有项目进行了令人惊讶的最终免费回忆测试。除了附近序列位置处呈现的项目之间的标准邻接效应之外，我们还同时观察到不同列表中呈现的项目之间的邻接效应。后一种连续性效果延伸到多个列表或数百秒，远远超出了可归因于保存少量整数项目的缓冲区的范围。
A contiguity effect-the finding that stimuli that occur close together in time become associated to each other-is observed between words that are separated by several seconds. The traditional account of contiguity effects is that item representations become associated to each other while active in a short-term memory buffer-a limited-capacity store that can hold a small, integral number of items. Participants studied and free recalled 48 lists of words. At the end of the session, participants were given a surprise final free recall test on all of the items from all of the lists. In addition to a standard contiguity effect between items presented at nearby serial positions, we simultaneously observed a contiguity effect between items presented in different lists. This latter contiguity effect extended over several lists, or several hundred seconds, well beyond the range that can be attributed to a buffer holding a small, integral number of items.
