摘要: 采用视空间定位的短时记忆任务,研究记忆负载的增加对空间位置信息和时间顺序信息的记忆成绩的影响。结果表明,在记忆负载较低时,位置记忆和顺序记忆的成绩相同;当记忆负载逐渐增大时,位置记忆的成绩逐渐上升,而顺序记忆的成绩先上升后下降,两者出现显著性的差异。在这个过程中,短时记忆的加工发生相应的变化,体现了短时记忆加工资源的有限性。

Abstract: Short-term memory(STM) on visuo-spatial location has been studied from subspan to supraspan. The results showed that memory load had different effects on the memory of spatial location and the memory of time order information. For the memory of spatial location, better performance was observed with higher memory load. The memory of bine order information, however, increased first and then decreased when memory load increased. These results suggested that STM processing may change with different levels of memory load, and the resources of STM processing may be capacity-limited.
