摘　　要：采用线索-靶子范式的双线索实验程序,在简单觉察任务中,大范围操纵SOAs,考察中央视野和外周视野的IOR在时间进程特征上的差异,年轻人与老年人不同视野中IOR时间进程的异同。结果发现,中央视野IOR的量值小于外周视野,且消失得也更早,反映了中央和外周视野存在不同的注意调控机制;人和老年人在中央和外周视野上IOR的时间进程没有显著差异,提示在不同视野中IOR的消失时间不存在年龄差异。In this study, SOAs were manipulated on a large scale in a simple detection task with the cue-target paradigm in the double-cue procedure to explore the effect of the time course of IOR on the central and peripheral visual fields, as well as the age effect on them. One msuh showed that the magnitude of IOR in the central visual field was weaker than that in the peripheral fidd, which also disappeared earlier. This suggests that the two spatially separated attention systems modulate the two regions of the visual field.As the other result revealed, an insignificant difference of the time course of IOR in two regions of the visual field between the young and the old indicated that the offset of IOR was not affected by the age effect in each visual field.
