三个实验采用操作广度测量和Nelson-Denny阅读能力评估，考察了策略使用对工作记忆广度成绩的影响以及工作记忆广度成绩与高级认知功能之间的相关性。参与者完成了两个版本的操作跨度测量的前/后测设计。在每项研究中，一半的参与者在后测之前接受了策略指导。在研究1中，工作记忆广度分数增加的结果，使用排练策略。在研究2中，三种不同的策略（排练。图像和语义）进行了比较。低跨度。尤其是从排练策略中受益。此外，工作记忆广度得分和Nelson-Denny阅读能力综合得分之间的关系得到加强，这表明，策略的使用，除非控制，可以掩盖“真正的”工作记忆广度和阅读能力得分之间的关系。在研究3中，控制了使用研究2中描述的策略所花费的时间。虽然没有特定的跨度组受益于使用任何一种策略，WM跨度分数获得而参与者使用的排练策略，再次。更能预测阅读能力。在WM跨度的评估过程中，战略使用的变化控制的重要性进行了讨论。(C)2003年爱思唯尔公司All rights reserved.
Three experiments examined how strategy use influences working memory (WM) span performance and the correlation between WM span scores and higher cognitive function, using the operation span measure and the Nelson-Denny assessment of reading ability. Participants completed two versions of the operation span measure in a pre-/posttest design. In each study, half of the participants received strategy instructions prior to post-test. In Study 1, WM span scores increased as result of using a rehearsal strategy. In Study 2, three different strategies (rehearsal. imagery, and semantic) were compared. Low spans. in particular, benefited from using a rehearsal strategy. Also, the relationship between WM span scores and Nelson-Denny reading ability composite scores was enhanced, suggesting that strategy use, unless controlled for, can mask the "true" relationship between WM span and reading ability scores. In Study 3, time spent using the strategies described in Study 2 was controlled. Although no particular span group benefited from using any one strategy, WM span scores obtained while participants used the rehearsal strategy was, again. more predictive of reading ability. The importance of controlling for variation in strategy use during assessments of WM span is discussed. (C) 2003 Elsevier Inc. All rights reserved.
