Studies of working memory demonstrate that some forms of information are retrieved by a content-addressable mechanism (McElree & Dosher, 1989; McElree, 1996, 1998), whereas others require a slower search-based mechanism (McElree & Dosher, 1993). Measures of the speed and accuracy of processing sentences with filler-gap dependencies demonstrate that the probability of maintaining a representation of a filler item decreases as additional material is processed, but that the speed with which a preserved representation is accessed is unaffected by the amount of interpolated material. These results suggest that basic binding operations in sentence comprehension are mediated by a content-addressable memory system.
对工作记忆的研究表明，某些形式的信息是通过内容可寻址机制检索的（麦克尔里和多舍尔，1989年；麦克尔里，1996年、1998年），而其他信息则需要较慢的基于搜索的机制（麦克尔里和多舍尔，1993年）。对带有填充语-空位依存关系的句子进行处理的速度和准确性的测量表明，随着更多材料的处理，保持填充语项目表征的概率会降低，但已保存表征的访问速度不受插入材料数量的影响。这些结果表明，句子理解中的基本绑定操作是由内容可寻址记忆系统介导的。
