在不同注意定向条件下是否出现返回抑制的知觉优先

DOES PRIORITY OF PERCEPTION WITHIN INHIBITION OF RETURN EXIST UNDER DIFFERENT ATTENTIONAL ORIENTING

返回抑制中的知觉优先是指相对于非线索化位置，线索化位置的刺激被优先知觉到的现象。研究采用时序判断方法对不同注意定向下返回抑制的知觉优先现象进行了两个实验。实验1采用连续线索化的安排，发现当注意从线索化位置移开后知觉优先仍然存在；实验2采用同时呈现双线索（分配注意条件）的安排发现知觉优先也存在。这些结果证明知觉优先不是在特定的注意定向条件下才出现的，而是具有更大的普遍性，因而支持返回抑制的反应性观点。

Priority of Pereephon (POP) within inhibihon of return (IOR) means that astimulus in the cued position will be perceived earlier than that in the uncued positionin contrast to the RT data. The aim of this study was to find if POP existed underdifferent attentional orienting. Two experiments were carried out by method oftemporal order judgements (TOJs) within IOR paradigm. College students were servedas subects. Experiment 1 showed that POP existed at locations being cued successi-vely; experiment 2 showed that POP also existed when attention was distributed bydouble cueing. It was concluded that POP could exist at different conditions of visualorienting within IOR, not only under focused attention. These results implied that POPwas a relatively general phenomenon in nature and could be considered as strongsupport for the response-related view on IOK
