摘　　要：以工作记忆广度、提取速度作为因变量指标,探讨了聋人及听力正常人在工作记忆中的差异。研究结果表明:(1)聋人的言语工作记忆广度小于听力正常人,而其视空工作记忆广度又显著大于听力正常人;(2)任务难度对工作记忆广度有着显著的影响,但它对聋人及听力正常人在工作记忆中的差异影响不大。(3)聋人在任务中的提取速度慢于听力正常人。Using working memory span and retrieval speed as the dependent variables, the author compared the differences of deaf and normal subjects in working memory. The results shows that: (1) the deaf group's verbal working memory span is smaller than that of normal group, but their visual-space working memory span is apparently bigger; (2) the difficulty of the task has a distinct influence on the working memory span, but it has no significant influence on the differences of the two groups; (3) the deaf's retrieval speed is slower than that of normal subjects.
