摘　　要：研究共选取66名本科生,采用修正的阅读广度实验范式,探讨微观标记类型、位置及识记数量对被试短时记忆信息提取的影响。实验1发现:标记类型和位置主效应在正确率上均显著。实验2发现:(1)基于被试:正确率上,标记类型和识记数量主效应均显著;反应时上,仅标记类型和识记数量主效应显著;(2)基于项目:标记类型、识记数量以及二者交互作用均显著;当要求识记词的数量≥7个时,标记类型差异显著。This study aimed to explore the influence on the information extraction from short-term memory caused by the different types and positions of text micro-signal. 66 undergraduates were chose to test by the modified reading span paradigm. The results showed that： （1） According to the analysis of partici- pants, main effects of the types of micro-signal and the number of words kept in the short-term memory were significant in accuracy rate. But the main effect of micro-signal and the number of words kept in the short-term memory was only significant in the accuracy rate. （2） According to the analysis of items, main effects of the types of micro-signal, the number of words and the interaction of these two variables were all significant. The difference between two types of micro-signal was significant when the number of words which asked participants to remember was more than 7. However, there was no difference among three positions of micro-signal during the sentence reading.
