摘要
该实验操作探测数字在记忆集中的位置来研究短时记忆的提取机制。结果发现：用Ｓｔｅｒｎｂｅｒｇ范式研究短时记忆提取机制存在缺限：操作记忆集不能反映被试的搜索过程。该研究显示：短时记忆的提取不是以自始至终或平行扫描为前提。短时记忆的提取机制受记忆集大小的影响较大。记忆集小于３时，短时记忆的提取是系列自中断扫描；记忆集大于３时，短时记忆的提取以记忆项目的痕迹强度为依据。
In order to study the process of short-termmemory's retrieval, the matching position was used asthe independent variable. The result showed that selfterminated scanning might in fact be more efficient inthe retrieval of short-term memory in the memory setof less than three items. When the memory set was ofmore than three items, the retrieval of informationfrom short-term memory was based on the strength ofmemory track. This paper suggested that Sternbergparadigm couldn't be used in the retrieval of information from short-term store. The result was discussed interms of short-term store across a range of memoryset.
