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.

Key words: visuo-spatial location, short-term memory(STW), supraspan, STM processing, resources of STM processing
