摘　　要：工作记忆是一个容量有限的系统或机制,在言语认知活动中具有重要的作用.本研究以秦巴山区健康成人为被试,通过言语流畅性、句子理解、数字工作记忆广度实验,比较了他们的言语流畅性和句子理解状况,进一步探索言语认知与工作记忆广度的关系.研究发现:(1)在言语流畅性中,高工作记忆广度被试的言语流畅性好于低工作记忆广度被试.(2)在句子理解中,工作记忆广度的主效应显著,高工作记忆广度被试的句子理解水平好于低工作记忆广度被试;工作记忆广度与难度、句式和句图一致性之间没有交互作用.Working memory is a system or mechanism with limited capacity,and plays an important role in verbal agnitivel activities.Healthy adults with different working memory span in Qin-Ba Mountain Areas take part in the experiments.Their verbal fluency,sentence understanding and numberic working memory are researched and their verbal fluency and sentence understanding are compared,further,the relationship between speech cognition and working memory span are explored.It find that,（1） In verbal fluency,verbal fluency of the subjects with higher working memory span are better than that of the lower.（2） In sentence understanding,the main effect of working memory span is significant,sentence understanding level of the subjects with the higher working memory span are better than that of the lower;there are no interaction between working memory span and the difficult level of sentence,sentence patterns,and sentence-picture consistency.
