摘　　要：采用线索-靶子范式,比较了单线索和双线索条件下年轻人和老年人返回抑制时间进程的发展趋势。实验1采用单线索化程序和觉察任务,SOA分为9种水平;实验2采用双线索化程序和觉察任务,SOA分为10种水平。结果显示:线索化阶段的注意分配和年龄对返回抑制的时程发展产生影响。(1)在单线索条件下,老年人返回抑制的出现时间比年轻人晚约200ms,消失的时间比年轻人早约1000ms。(2)在双线索条件下,老年人返回抑制的出现时间比年轻人晚约100ms,消失的时间比年轻人早约500ms。The research explored the effects of distribution of attention and age in cueing process on the timing development of IOR. Experiment one takes the forms of single cue procedure and detection task and SOA is divided into nine levels. Experiment two takes the forms of double cue procedure and detection task and SOA is divided into 10 levels. The time course and its age effect have been discussed. The results show that： （1） Under the condition of exogenous attention, IOR of the old adults emerges around lOOms later and disappears around 500ms earlier than the young adults; （2） Under the condition of endogenous attention, IOR of the elderly emerges around 200ms later and disappears around 1000ms earlier than the young adults.
