多重位置上的返回抑制:对注意动量说的检验

采用多重线索范式在返回抑制容量研究中鉴别注意动量说与抑制说. 实验一探讨了中央线索对返回抑制容量的作用，发现中央线索与线索数量的随机化均能独立增大返回抑制量. 实验二和三分别探讨了线索时间对序列和同时线索条件下的返回抑制容量的影响，发现随线索时间的增加，相隔序列线索条件下的返回抑制容量逐渐增加，而对相邻序列线索条件的影响较弱. 实验结果不支持注意动量说，倾向于支持抑制说.

INHIBITION OF RETURN AT MULTIPLE LOCATIONS: TESTING THE ATTENTIONAL MOMENTUM VIEW

Using the multiple-cuing paradigm，the present study tested the attentional momentum view at multiple locations，and explored the impact of exposure duration of peripheral cue on the capacity of inhibition of return (IOR). Experiment 1 aimed to investigate the influence of central cue on the capacity of IOR. The results indicated that both central cue and stochastic assignment of the number of peripheral cue can facilitate the strength and capacity of IOR. Thus，the fundamental paradigm of studying the capacity of IOR must be similar to what done by Danziger et al (1998). Determining the impact of exposure duration of cue on the capacity of IOR in successive and simultaneous cueing conditions are the goals for experiment 2 and 3，respectively. The analysis showed that the capacity of IOR increased gradually with the increment of exposure duration in nonadjacent condition，but is not for the adjacent condition. Attentional momentum view can not explain our results. Therefore，the results tend to support the role of inhibition in IOR.
