Z Zhang · Yingyong xinlixue · 2009
Three main hypotheses of task switching mechanism, task-set reconfiguration,task-repetition benefits and cue-repetition benefits,are summarized.Task-set reconfiguration hypothesis considers task switch as a top-down executive control process based on the intention of individual behavior.On the contrary,task-repetition benefits hypothesis and cue-repetition benefits hypothesis both regard it as a bottom-up auto- matic control process initiated by the external stimulus. Therefore,the crucial difference among the three viewpoints is whether task switch involves executive control processes.The argument in the field is analyzed, and the relevant research is also suggested.
