摘　　要：为了验证工作记忆广度有限性的两种假设,即资源共享模型和记忆消退说,同时探讨存储负荷对工作记忆广度的影响,实验要求被试完成工作记忆广度任务.结果发现:存储负荷有显著的主效应,保持时间有显著的主效应,但保持时间的主效应表明工作记忆广度任务中信息的遗忘不是记忆的消退.In order to validate two hypotheses about the limitations of working memory span,namely,resource-sharing model and memory-trace decay hypothesis,and to investigate the effects of storage load on working memory span,the subjects were required to fulfill the task of working memory span.Two-way analyses of variance of the span data revealed that there were significant main effects of storage load and retention duration.But the significant main effect of retention duration proved that the forgetting of information was not the memory-trace decay in the working memory span task.
