摘　　要：目的考察工作记忆负荷对返回抑制影响的年龄效应。方法将基本返回抑制范式和工作记忆任务的结合,以大学生和老年人为被试。结果在中等工作记忆负荷水平条件下,老年组返回抑制消失;在高工作记忆负荷水平条件下,年轻组返回抑制消失。结论空间工作记忆负荷水平和年龄影响返回抑制。空间工作记忆负荷的增加对老年组返回抑制影响更大。Objective This study aimed to investigate the impact of spatial working memory load and age on returning suppress. Methods The spatial working memory was used to test the basic paradigm of returning suppress in this study. To include the effect of age, 22 college students and 22 elderly people were tested. Results With a medium level of working memory load, the returning suppress of the elderly group disappeared; with a high level of working memory load, the returning suppress of the student group disappeared. Conclusion The level of spatial working memory load and age affect returning suppress. The influence of spatial working memory load on the returning suppress is greater to the elderly group.
