摘要
本研究探讨了工作记忆负荷对任务切换的影响。在实验中采用双任务范式,设置了低、中、高三种工作记忆负荷条件。结果发现,在三种工作记忆负荷条件下均存在明显的切换损失现象,但在不同的负荷条件下切换损失量没有显著差异。这表明任务切换过程中不存在与工作记忆相关的切换特异性过程,从而为竞争学说以及多执行中枢说提供了新的证据。
The objective of present study was to investigate the relationship of working memory and task switching. 18 college students performed task switching tasks under three different working memory loads. The results showed that there was no significant interaction between task switching and working memory. The study provides new evidence in favor of the competitive view on the mechanisms of task switching, it is also in line with the theories which assume multiple executive processes.
